Abstract

Manta rays are charismatic species that symbolize the natural value of our ocean. The unique morphology and behavior of this species attracts people to witness its beauty. Manta ray watching tourism has become a popular recreation activity to view wildlife in their natural habitat. Numbers of manta ray tourists estimated more than double globally and generate USD 140 million across 23 countries with a number of hotpots locations including Maldives, Mozambique, Sudan, Hawai, and Indonesia. Manta ray watching tourism has brought different arguments in terms of its sustainability. Utilizing data collection of scientific articles and distribution of questionnaires to a number of stakeholders in Nusa Penida, Komodo, and Raja Ampat, this study provides a review of impacts of manta ray watching tourism to economy, ecology, and socio-cultural aspects. The results suggest that manta ray watching tourism would effectively support the economic viability, ecological sustainability, and social equity with good governance, law enforcement, best practices, and active engagement of multi-stakeholders.

Abstract

Manta rays (Mobula birostris and M. alfredi) are flagship species symbolized the high biodiversity of marine ecosystem. There are a number of manta ray aggregation in Indonesia, including Raja Ampat. Manta Sandy is a cleaning station of manta ray located in Dampier strait popular for manta ray watching tourism which visited by hundreds of tourist daily. It is highly important to identify the estimate population of manta ray in this area for species conservation and management considering the tourist volume. This paper analyzes the population dynamics of manta ray in manta sandy by utilization of mark-recapture method followed by pattern-matching approach from data set of 500 individuals that has been recorded by Conservation International Indonesia. Furthermore, this paper also assessed factors contribute to manta sightings. Photographic identification collected from camera traps during December 2017-February 2018 and July-August 2018 resulted in more than a hundred accumulative identified photo ID in addition to dozens of new individuals. In addition, factor of chlorophyll, temperature, and current are the main factors affecting the manta sightings. This study demonstrated manta sandy as one of the aggregation areas in Raja Ampat that play an important role both for ecology and economy value.

Age determination of Crustaceans by growth marks in gastric ossicles : State of the Art
Daniel J. Bucher

Southern Cross University, NSW, Australia


Abstract

In 2011 a team from Southern Cross University published the first description of concentric growth marks in the gastric ossicles of crabs and lobsters from a range of habitats and latitudes and concluded that the number of marks was consistent with the approximate ages of the animals. Subject to future validation we pointed to the potential of these marks to provide the first direct age determinations for decapods. Since then ossicular growth marks have been used to provide putative ages for a range of crab, shrimp and lobster species around the world. However, definitive validation is still lacking for most of those species. Fluorochrome stains such as calcein that bind with the cuticular minerals have the potential to be remobilized during pre-moult decalcification, so the search is on for a chitin-specific alternative. Comparisons of growth curves generated by direct ageing and tag-recapture indicate that, for some species, we can be quite confident of the annual nature of the growth marks, and for others it is clear that the number of marks is proportional to age, not merely size, but the relationship may not be one-to-one. Deep-water species from the Banda Sea as well as common shallow-water species may be suitable for testing the method in tropical waters.

Abstract

The research aims to study Rhizophora leaves extract to inhibit pathogens and protects on tiger prawn. The leaves of Rhizophora were chopped, dried, macerated and extracted in three different solvents, namely ethanol, water and see water. In vitro inhibitory tests were performed using disc diffusion and minimal inhibitory concentration methods.The in vivo test on tiger prawn was given by submersion, which then tested with V. harveyi and Saprolegnia sp. The observation and inspection covered clinical symptom, pathological anatomy, total vibrio count, survival rate, and Relative Percentage of Survival. The result showed mangroves leaves extract can inhibit Vibrio haveyi on tiger prawn, improve survival rate and relative persentage of survival. The best mangrove extract that can inhibit and protect the tiger prawn from pathogen infection is ethanol extract of Rhizophora mucronata 1,250-1,500 ppm, followed by water extract 1,500 ppm, and sea water extract 1,500 ppm.

Survey and analytical tools for assessing small-scale invertebrate fisheries
Steven W. Purcell

National Marine Science Centre, Southern Cross University, Australia


Abstract

Small-scale fisheries are prevalent in the tropical Indo-Pacific region and provide for millions of coastal livelihoods, yet many remain understudied in comparison to industrial-scale fisheries. In past decades, assessments of small-scale fisheries were based heavily on catch records and fishery-independent population surveys. Socioeconomic surveys of fishers offer a more cost-effective means to gain fishery-dependent data on catch composition, catch rates, fishing effort, ecological footprint of fisheries, fishing costs, and fisher incomes. The presentation draws on lessons from small-scale fisheries in the Pacific Islands. New survey, analytical and graphical tools offer approaches for understanding stock status, species at risk, drivers of overfishing, and for identifying opportunities for improving fishery performance and fisher livelihoods. Fishery assessments should go beyond counting women in fisheries and provide evidence for fishery management recommendations. Amidst the dreary prognoses for many small-scale fishery stocks, such approaches holds bright promise for better understanding and managing small-scale fisheries.

Abstract

The search for new antibiotics from a variety of sources that have the potential to produce bioactive metabolite compounds is essential to solve the increasing problem of microbial resistance. Recently, one of the most widely studied for new antimicrobial sources is marine derived fungi. The aims of this study were to isolate endophytic fungi of marine sponges collected from Sekotong Beach Lombok, Indonesia and determine their antimicrobial activity. Fungi isolation were conducted in yeast extract, peptone, and dextrose (YPD) agar medium and each pure fungi was fermented for 21 days in YPD broth medium. Culture media and mycelium were separated by filtration method. The culture media was extracted by liquid liquid extraction and mycelium was extracted by maceration method using ethyl acetate. The dried extracts then tested for their antibacterial activity against Escherichia coli ATCC8739, Staphylococcus aureus ATCC6538, and Candida albicans ATCC 10231 using paper disk diffusion method. Extracts which showed antimicrobial activity on 250 ug/disk content were determined their minimum inhibitory concentration (MIC) and minimum bactericidal or Fungicidal concentration (MBC or MFC). The results of this research were obtained 12 fungi isolates that were coded as FSKT1 until FSKT12. The lowest MIC and MBC value against E. coli was showed by mycelium extract of FSKT10 with concentration of 128 and 256 ug/mL, respectively. The lowest MIC and MBC value against S. aureus was showed by medium extract of FSKT9 with concentration of 64 ug/mL, respectively and against C. albicans with concentration of 128 and 512 ug/mL, respectively. The antimicrobial activity observed in this research indicates that the endophytyc fungi of the marine sponge could be considered as new sources of antibiotics.

Abstract

The cultivation of white shrimp Litopenaeus vannamei is one alternative for the development of shrimp farming. Poor water quality over time, especially in intensive ponds due to organic materials is a common problem. Alternative solution of water quality handling is through the provision of probiotics on aquaculture. The study was conducted from May to June 2018 at the Balai Benih Ikan Pantai (BBIP) Ghonebalano, Muna Regency, Southeast Sulawesi, Indonesia. Research to determine the doses of probiotics that occur for the growth and survival of white shrimp. The study used a Completed Randomized Design with four probiotic dosage levels: Control (without probiotics), Treatment I (10 ml per container), Treatment II (20 ml per container), and Treatment III (30 ml per container). The results showed that vannamei shrimp growth was 1.92 g (Control), 2.25 g (Treatment I), 2.60 g (Treatment II), and 2.05 g (Treatment III). While the survival of vannamei shrimp was 83.33% (Control), 86.11% (Treatment I), 93.06% (Treatment II), and 91.67% (Treatment III). Analysis of variance at 95% confidence interval (0.05) effect of treatment on growth showed application of probiotic with different dose did not give real effect to daily growth rate (Sig 0.05>0.188), but significant effect on absolute growth (Sig 0.05<0.001 ) and survival (Sig 0.05<0.024) vannamei shrimp L. vannamei.

Abstract

Aquaculture technology continues to growing rapidly through the application of environment-friendly intensive technology through the application of probiotics as biological control. One of the factors that can affect the growth and survival of white shrimp with the application of probiotics is stocking density. The study was conducted in May to June 2018 at the Balai Benih Ikan Pantai (BBIP) Ghonebalano, Ghonebalano Village, Duruka District, Muna Regency aiming to know the growth and survival of white shrimp L. vannamei with the application of probiotics in different stocking densities. The study used a complete randomized design with three treatment levels of density, i.e. treatment I (18 individuals per container), treatment II (24 individuals per container), and treatment III (30 individuals per container) with three replications. The results showed that the highest daily growth was obtained at treatment II of 5.88% per day, compared with treatment I (5.86% per day) and treatment III (5.74% per day). The highest absolute growth was obtained at treatment II (2.43 g per individuals) then treatment I (2.15 g per individuals) and lowest at treatment III (2.02 g per individuals). Survival in treatment I and II was 88.89%, while treatment III was 86.67%. Variance analysis at 95% confidence level (0.05) indicated that density of different stocking had no significant effect on daily growth rate, absolute growth and survival rate of vannamei shrimp with probiotic application.

Abstract

Coastlines and islands across Australia and Indonesia hold some of the highest marine biodiversity in the world. Among this native biodiversity are also many endemic species, found nowhere else in the world. Unfortunately, growing human population and consumption of natural resources threaten the marine environment through habitat destruction, pollution, overfishing and the introduction of non-native species. The last decades have seen a dramatic increase in species being moved to outside of their native ranges, intentionally for aquaculture or unintentionally attached to the hulls of vessels around the world. Once introduced to a new location, non-native species can compete with native species and alter local ecosystems, becoming invasive. In order to manage non-native species, it is important to first identify them and investigate their distribution, potential origin and impacts. Although the taxonomic identification of species is essential, once this is done and a reference DNA sequence generated, DNA barcoding is able to free taxonomists from the time-consuming identification of previously described species. Other DNA methods such as microsatellites and SNPs are further able to investigate the genetic structure and diversity of whole populations, inferring on the species potential origin and impact. Given the challenge presented by the hundreds of species in marine biodiversity hotspots, new metabarcoding techniques able to produce hundreds of sequences from environmental DNA (eDNA) are being implemented for the monitoring of human impacts on marine biodiversity. In this presentation we will give examples from Australia and Indonesia on how these molecular methods (DNA barcoding, population genetics, eDNA metabarcoding) have been applied to the investigation of non-native species such as the green mussel Perna viridis, sea squirts Didemnum sp. and the black sponge Terpios hoshinota.

Abstract

The Banda Sea experiences a strong upwelling between April and November associated with the seasonal strengthening of the trade winds. Data of surface wind, sea surface temperature (SST) and salinity in the period of 1990-2008 were used to further study the response of upwelling to the local and remote forcing in the Banda Sea. A local forcing (Ekman Pumping) during Southeast Monsoon plays role in contributing the upwelling intensity indicated by shallower thermocline and colder SST. In addition, this study exhibits that the upwelling strength is controlled remotely by El Nino Southern Oscillation (ENSO) where during El Nino (La Nina) periods in Southeast Monsoon, the upwelling decreases (increases) in the Banda Sea.

Abstract

Kelvin wave propagation along the southern coasts of Sumatra, Java, and Lesser Sunda Islands generated by the Madden-Julian Oscillation (MJO) phase 3 (April 28 - May 6, 2004) has been studied by using sea surface height anomaly (SSHA) data simulated by a 1/8 global version of the HYbrid Coordinate Ocean Model (HYCOM), satellite-observed outgoing longwave radiation (OLR) data, and zonal wind data. In order to investigate the influences of MJO known as the intraseasonal oscillation (30-90 days), analysis of the data was carried out after 10-100 days band-pass filtering.

The analysis results show that the intraseasonal oscillation SSHA along the coasts of Sumatra, Java, and Lesser Sunda Islands generally have a spectral peak at 91 days associated with the spectral peak of the MJO, except for Sunda Strait (61 days), southern coast of West Java (55 days), Sawu Sea (61 days), and Ombai Strait (100 days). Further analysis suggests that the MJO phase 3 generates Kelvin waves propagating eastward along the coasts of Sumatra, Java, and Lesser Sunda Islands with phase speed ranging from 2.56 to 3.85 m/s.

Abstract

Turtles is hard-headed animals and include as protected animal according to convention on international trade in endangered species I, so that all forms of the utilization of sea turtle must be have serious attention. The provision of protection status was not enough to recover or at least maintain population of sea turtles in Indonesia. That was become an obstacle to preserve sea turtles in North Halmahera especially in Meti Island. The aim of this research was to identification the species of sea turtle and spawning and hatching areas of sea turtle around Meti Island. This research used purposive sampling method according to information obtained from community, while data of the apendik and habitats of sea turtle taken directly on research area. The identification found 3 species of sea turtle in Meti Island, Chelonian mydas, Eretmochelys imbricata and Lepidocheys olivacea. There are two location of spawning and hatching of sea turtle, on meti Island coast and Pasir timbul Island, the part of Meti Island administration. Granular domination of the substrats at spawning and hatching location was medium sand , fine sand, and course sand. The slope of the coast at the location of spawning and hatchng are approximately 35 degree while the upper side had more than 40 degree at Pasir Timbul Island. Marine vegetation at the location of spawning and hatching area dominated by sea grass and sargassum, as the suitable area for rearing of sea turtle. Shore vegetation at two location on Meti Island consist of Hernandia nymphaeifolia, Scaevola taccada, Thespesia populnea, Pandanus sp, Guettarda speciosa, Terminalia catappa, Crinum asiaticum, Millettia pinnata, Cycas circinalis, Thuarea involute, Cardia subcordata while vegetation of Pasir Timbul Island consist of Ipomoea pes-caprae, Wedelia biflora, Spinifex littoreus, Scaevola taccada, Argusia argentea, Terminalia catappa, Pandanus sp, Hernandia nymphaeifolia, Cocos nucifera.

Abstract

Seagrass bed is one of the ecosystem that directly adjacent to coral reefs and serve several important ecological roles especially by protect the reef from sedimentation from land. With this reason, the status of seagrass beds were also monitored in Coral Reef Rehabilitation and Management Program (COREMAP), which one of the sites is in Ternate and its surroundings. In order to assess the latest status of seagrass beds, on July 2018 a study has been done on 10 locations in this area. Seagrasses species composition and their canopy cover data were gathered using transect method which placed perpendicular to shore line. There are eight seagrasses observed in this study, with most of the locations consist of 5-7 species. Thalassia hemprichii being the most common species by inhabiting all of the locations. Averages of canopy cover in seven locations were below 59.9% which make their status considered as less healthy, and three locations were below 29.9% which considered as poor. Overall, the status of seagrass beds in this area is less healthy with moderate canopy cover. This status has remain the same every year from 2015.

Abstract

Tidal bore is an infrequent natural phenomenon, it is usually happened close to the estuary. In Indonesia, it happens at Kampar river Riau province. Some factors that caused this phenomena are tides wave and water bottom topography. In this paper, we simulate propagation of tidal bore in Kampar river based on shallow water equations (SWE). We use staggered grid conservative scheme to discretize the SWE. Next, we apply bottom topography of kampar river and tides wave profile there into our scheme. Finally, we present numerical simulation that show how tidal bore propagate along the Kampar river.

Abstract

Tuna (family Scombridae, tribe Thunini) is one of the main seafood commodity in Indonesia. The Banda Sea is one of the important tuna fishing ground in which it belongs to fisheries management area (WPP) 714. More recently, some areas of the Banda Sea have been preserved for the yellowfin tuna conservation since 2015 because they are indicated as tunas spawning ground. Despite the issued MMAF ministers decree on the conservation area, not much information is available about tuna larvae distribution in the Banda Sea and its connection to the conservation area. This study aims to provide the information on the tuna larvae encompassing the spatial distribution and tuna larval development stage to support the background of the conservation area. Tuna larvae data were collected from several surveys that were done in the Banda Sea. In total there were 21 surveys over four decades. There were three types of gears used in collecting tuna larvae sample: Rectangular Midwater Trawl (RMT), Bongo Net (BN) and Isaacs Kidd Mid-water Trawl (IKMT). A total of 143 stations have been sampled from these surveys and tuna larvae were found in 57 stations. Body length (SL) of larvae tuna was 7.09+- 0.38 mm (mean +- SE). Overall, tuna larvae found in the Banda Sea were in the pre-flexion, flexion, and post-flexion stage. This study supports the hypothesis that tuna may spawn in the Banda Sea. Therefore, more studies on tuna larvae need to be conducted to clarify the Banda Sea is an important tuna conservation location.

Abstract

The Banda Sea is one of the global hotspot for marine diversity. Prior attempts of reviews were only done in narrative and/or descriptive basis, but no systematic one has been done previously. This study aims to establish the current understanding of this ecosystem by systematically reviewing the published literature and consulting with the experts to identify knowledge gaps, and compare the Banda Sea to other major seas in Indonesia. A total of 219 studies have been reviewed comprises of 73 studies focused in marine biology, followed by 60 on marine geosciences, 45 in physical oceanography, 22 in marine pollution, 10 in chemical oceanography and 13 on social economy. Coastal habitats were the most studied, with a focus on economically important species. High fragmentation on process studies and incomplete substantial time series were the main obstacle of our capacity in identifying trends, environmental thresholds or major drivers of biotic interactions. We also highlight a lack of knowledge on the ecological functioning of the Banda Sea, including studies on microbial communities. Current understanding of the complexity, connectivity, and dynamics of the ecosystem is critical for further advanced studies in management for this ecosystem and for similar semi-enclosed tropical seas in Indonesia.

Faculty of Marine Engineering,
Institut Teknologi Sepuluh Nopember


Abstract

Indonesia is one of the main fish producers in Southeast Asia. In recent years, aquaculture in Indonesia has seen a significant increase of total aquaculture production, especially fish. Increasing fish production requires the development of fish transportation technology. Live fish carrier is a special type of vessel for transportation of live fish, especially for fish whose prices increase when sold alive. Most often this vessel type is used in aquaculture for transporting the fish stock from farm to factory.

Live fish vessel designed to significantly enhance fish welfare, hygiene, quality and environmental aspects. This is a great advantage and will reduce stress among the fish. As such, this ensures fish of higher quality while also improving fish growth. A live fish carrier is equipped with tanks or wells filled with water for the storage of fish during transportation. The live fish carrier is often being called well-boat, as the tanks on the vessel is called wells.

Live fish carriers must have adequate performance in terms of stability, especially in damage conditions. Improving stability of the ships performance in damaged conditions can be done by reducing the permeability of the room that has a high probability of damage. Permeability is used in ship survivability and damaged stability calculations in ship design. The permeability of a compartment is a percentage of 0 to 100. Alternately, the permeability may be a coefficient from 0 to 1. The permeability of a space is the percentage of volume of the space which may be occupied by seawater if the space is flooded. The remaining volume [not filled with seawater] being occupied by machinery, cargo, accommodation spaces, etc.

Permeability reduction can be done by adding foam. Foam is one of the low density materials, in other words has a large volume with a small weight. one type of foam that can be used is Low-density polyethylene foam. Low-density polyethylene foam has numerous applications because of its many desirable properties including water-resistance, chemical resistance, energy-absorbance, buoyancy and cushioning characteristics.

Abstract

Given the significant threats against coral reefs, there is an urgent need to develop diagnostic tools that can simultaneously identify 1 those reefs at greatest risk of bleaching in response to elevated temperatures and 2 corals and reef sites featuring a marked capacity for resilience. However, progress in coral reef diagnostics has been thwarted by both logistical and biological issues. For one, no pristine control reefs exist on Earth; how, then, can we distinguish between healthy and sub-lethally stressed corals prior to physiological data acquired prior to the Industrial Revolution? This dilemma currently limits the utility of employing molecular biomarkers uncovered in aquarium experiments in one part of the world to make conjectures about the physiological status of conspecifics elsewhere; the experimental controls in such tank experiments were likely to have been affected by global climate change-related stressors (notably elevated temperatures and pCO2 levels). Given this issue, we instead used a coral health dataset obtained from the South Pacific to 1 model coral behavior in an endosymbiosis-tailored, statistically rigorous framework and 2 make predictions as to which colonies/reefs may be at most risk by exploring the hypothesis that variability in coral response, rather than the mean response of individual response variables measured, is a more useful metric for those interested in forecasting behavioral change in reef corals and other marine invertebrates.

Abstract

Based on the geographical conditions of Indonesia, especially the eastern region of Indonesia, a national sea transportation system is needed that can be a bridge for remote, isolated and undeveloped islands using pioneering sea transportation. The problem is when the pioneer ships carry out maintenance and repairs, where the pioneer ship population of 80% operates in the eastern part of Indonesia and 20% operates in the western region of Indonesia, while 70% of shipyards are located in Western Indonesia while the remaining 30% are located in Eastern Indonesia. The purpose of this study is to determine the appropriate type of shipyard. The method used in this study is to use the fishbone and SWOT methods and 11 locations in Indonesia are selected for surveys. Construction of shipyards for pioneer ships takes into account shipyard availability in the area of operation, the number and type of vessels operating. The study results show that the best shipyard location to support the operation of pioneer ships is located in the Bitung Region or in the Sorong Region with the type of shipyard in the form of a slip way.

Abstract

Maluku province is an archipelagic province consists of about six hundreds islands, has total area about 581,376 sq.km, where seas are 527,191 sq. km 90 percent and land 54,185 sq.km 10 percent. The villages at Maluku 40 percent are without electricity and it is impossible to provide at every remote small island a power supply because lack of infrastructure such as: jetties, transportation, communication.
Solar and wind penetration into existing diesel systems to meet the load of a remote island in Maluku province could be assessed.
Techno economical analysis to perform a design of an optimal hybrid solar- wind-diesel power plant to serve the loads of the villages at the remote islands. The hybrid plant with 20 percent of solar energy, 20 percent wind-energy penetration, and diesel generators was found to be the optimal plant and it becomes feasible for wind speeds in the order of 4 meter per second and more regardless of the diesel fuel cost. Utilizing this plant for electricity generation decreased the operational hours of the diesel generators by 10 percent in comparison with the diesel only situation. This led to a decrease of 20 percent in the diesel consumption. Consequently, 10 tons of greenhouse gas emissions can be avoided annually utilizing the proposed hybrid power plant for electricity generation in place of the existing diesel only system. Based on the obtained results, the studied village in particular at the remote islands of Maluku province in general are prospective candidates for deployment of the proposed hybrid solar wind diesel power plant for electricity generation.

Abstract

The current state of the Banda Sea with a long history as one of the important fishing ground in Indonesia is entering a new chapter. The government of Indonesia issued Ministerial Regulation Marine Affairs and Fisheries No 4 2015 stating a huge temporary closure area in the Banda Sea encompassing 126-132E, 4-6S or almost 130000 km2 of the total area during the period of October-December each year. The closure area is preserved as spawning and breeding ground of yellowfin tuna. This regulation leads to controversy since lack of the scientific basis behind it and prohibiting all fishing activities including non-tuna fishing vessels. Despite the regulation has been recognized since January 2015, the performance of this closure area has not yet been investigated. This study attempts to identify the amount of the fishing vessel operated in the Banda Sea by using VMS data during 2014-2017 period and its relation with the compliance in the closure area. Before the regulation was effective, the total number of fishing vessel operated in the Banda Sea was 249 in 2014. It decreased to 104 in 2015, 214 in 2016 just two years after the regulation was applied. The number of the vessel was increased significantly to 747 in 2017. A total of 44 fishing vessels were detected being operated in the closure area in 2014. However, it decreased significantly to 10 vessels in 2015 and 7 vessels in 2016. The increase in offenses occurred in 2017 when 32 vessels fished in the closure area. The study suggests an integrated management for monitoring and surveillance as the consequence of raise number of fishing vessels operated in the Banda Sea.

Abstract

Sea turtles was one of some sea protected animals according to government regulation no. 7 1999. Living turtle migrate along area the Pacific Ocean, the Indian Ocean and Southeast Asia Ocean including Sea of Halmahera. In Indonesia there are 6 of 7 species of sea turtle in the world and 3 of them are in The Meti Island, The green sea turtles Chelonian mydas, Hawksbill sea turtle Eretmochelys imbricata and Olive ridley sea turtle Lepidocheys olivacea. All kinds of turtles in Indonesia category in a protected animal, but until now the catching activity and subsequent the utilization of sea turtle still widely practiced by the community of The Meti Island. Therefore the aim of this research was to analyze the knowledge and community understanding of existence and the utilization of the sea turtle. The data was taken through observation of sea turtle existence and interview with The Meti Island community. Result showed as 66.27% of respondences know about the existence of sea turtle, 36.61% know about the impact of utilization to sustainability of sea turtle but 39.64% still catch and using sea turtle as a consumption and trade. This show the lack of awareness in community about sustainability of sea turtle around The Meti Island. The high level of utilization of sea turtle shows the weakness of the function of monitoring and supervision by regional government to against the utilization of an animal that should have to be protected.

Abstract

The paper aim to examine the rise of maritime customary institutional authority in Aceh named Panglima Laot. In its history, during the kingdom of Aceh Darussalam, in addition to moving in the field of sea law regulation, Panglima Laot also enrolled in mobilizing warfare, sea defense and tax collecting in the sea region. In modern era, the recognition of Panglima Laot institution gained legitimacy through law No. 11 of 2006 concerning the Aceh Government article 98-99 and 162 paragraph (2) letter (e) which was then elaborated into The Qanun (local regulation) of Aceh No. 9 of 2008 on the development of customary life and customs and Qanun No. 10 of 2008 concerning customary institution. Besides examining the revival of Panglima Laot as the ruling authority of traditional maritime domain, this study also examines concerning the intersection between the authority of Panglima Laot which was traditional marine defense authority and modern defense authority in maritime affairs in Aceh under Indonesian Navy authority.

Abstract

Indonesias development is currently focused on infrastructure development both nationally and locally. One important aspect of national development with development policies from the periphery. This means that national development today makes the village as the spearhead of development in improving the welfare of society in a sustainable manner. Development of sustainable welfare can be realized if supported by the community in protecting the environment. The aim of the study is to see the process of changing peoples views from traditional economy to modern economy, from the weak economy to a strong economy, from subsistence economy to market economy, from dependence on independence to the outer islands and the foremost in Riau Province. By being given authority, it is widely expected that there will be two development processes from the edge, namely the development of villages and villages to build. The direction of the village development policy and strategy is directed at meeting the village minimum service standards in accordance with its geographical conditions, overcoming and developing the economic efforts of the village community and the development of human resources. In order for the development and empowerment process in the outermost and foremost islands to run in accordance with policy objectives, it must be supported by a disruptive bureaucracy village institution supported by a disrupted society customary institution. This study uses a qualitative approach with interview data collection techniques, FGD, Role Play and Simulation (RPS) documentation with interactive data analysis. With this study, it is expected that there will be policies and become village and customary institutions to be strong in the development and empowerment of communities in the outermost and leading islands in Riau Province.

Abstract

Solid waste problem is a time bomb in urban and suburban community. In the other hand, there is a lot of energy has been invested in the material in solid waste that can be mined easily. The old paradigm of
waste management with only transport and disposal patterns is unsustainable. Solid waste should be segregated at source and recycled. The problem is that it is not easy to change the habit and attitude of community towards solid waste handling. Oppression to segregate solid waste can cause waste dumped in the river in unsupervised places. Trash banks will be the solution and is a soft approach to attract people to sort out their own waste. They will benefit from this activity both clean environment and economic benefit and at the same time save energy. After the community is accustomed to solid waste segregation, the regulation of compulsory sorting of garbage can be applied firmly and effectively. At that time, the trash bank did not need to buy garbage from the community but it could be operated as a recycling center.
