ABSTRACTBiodiesel production was examined withScenedesmus obliquusin a recirculatory aquaculture system with fish pond discharge and poultry litter to couple with waste treatment. Lipid productivity of 14,400 liter ha−1year−1was projected with 11 cultivation cycles per year. The fuel properties of the biodiesel produced adhered to Indian and international standards.

This research was conducted for the purpose to overcome Indonesia waste problem. The samples are classified into garden waste, paper waste, wood, food waste, and MSW with objective to identify which type of waste give out more syngas since there is waste separation in Indonesia. All samples were treated by plasma gasification without pre-treatment (drying). Arc plasma torch used in this experiment was made by National Nuclear Energy Agency (BATAN) and used Argon as the gas source. Then the torch was connected to self-designed gasification chamber and gas washing system before injected into a gas bas for composition analysis. Another objective is to identify factors that may affect the gasification efficiency and the experiment shows that moisture content is not really affecting the efficiency but the duration of the process. The mass reduction of each samples were recorded, then the gas produced from the gasification process were analyzed. The result shows that food has the highest mass percentage reduced and producing the highest amount of hydrogen amongst other samples. However, treating MSW also produce considerably high amount of hydrogen. In conclusion, MSW direct treatment (without separation) using plasma gasification is feasible since it still produces desirable quality of syngas.

On 16 October 1996, a malfunction at the Swan Hills Special Waste Treatment Center (SHSWTC) in Alberta, Canada, released an undetermined quantity of persistent organic pollutants (POPs) into the atmosphere, including polychlorinated biphenyls, dioxins, and furans. The circumstances of exposure are detailed in Part 1, Background and Policy Issues. An ecologically based, staged health risk assessment was conducted in two parts with two levels of government as sponsors. The first, called the Swan Hills Study, is described in Part 2. A subsequent evaluation, described here in Part 3, was undertaken by Health Canada and focused exclusively on Aboriginal residents in three communities living near the lake, downwind, and downstream of the SHSWTC of the area. It was designed to isolate effects on members living a more traditional Aboriginal lifestyle. Aboriginal communities place great cultural emphasis on access to traditional lands and derive both cultural and health benefits from “country foods” such as venison (deer meat) and local fish. The suspicion of contamination of traditional lands and the food supply made risk management exceptionally difficult in this situation. The conclusion of both the Swan Hills and Lesser Slave Lake studies was that although POPs had entered the ecosystem, no effect could be demonstrated on human exposure or health outcome attributable to the incident. However, the value of this case study is in the detail of the process, not the ultimate dimensions of risk. The findings of the Lesser Slave Lake Study have not been published previously and are incomplete.

Blue Economy

Tantangan pengembangan ekonomi biru di Lombok adalah menurunnya habitat terutama rumput laut, terumbu karang dan bakau, karena tingginya tekanan ekonomi yang menyebabkan orang terlibat dalam eksploitasi sumber daya  perikanan. Tujuan riset adalah mereview penerapan konsep “Ekonomi Biru” pada usaha perikanan budidaya  di Kabupaten Lombok Timur. Data dan informasi dikumpulkan melalui penelusuran dokumen, laporan riset dan publikasi ilmiah terkait topik kajian. Dokumen-dokumen tersebut dianalisis secara konten (content analysis) dan direview dari aspek sosial dan ekonomi yang dijelaskan secara kualitatif. Hasil review menunjukkan bahwa 6 (enam) usaha perikanan dapat memberikan efek berganda yaitu budidaya  lobster, budi daya  rumput laut, pengolahan kepiting, pengolahan limbah kepala ikan, dan tambak garam mempunyai peluang menciptakan efek berganda, artinya keenam usaha tersebut dapat menciptakan alternatif mata pencaharian yang bisa berdampak pada peningkatan ekonomi rumah tangga. Title: Prospects of the Implementation of Blue Economy Concept on An opportunity Fisheries Bussiness in East Lombok DistrictThe challenge of developing a blue economy in Lombok is the decline of habitats, especially seaweed, coral reefs and mangroves, due to the high economic pressure that causes people to be involved in exploitation of fisheries resources. The aim of the research is to review the application of the concept of “Blue Economy” in aquaculture businesses in East Lombok District. Data and information were collected through documents investigation, research reports and scientific publications related to the topic of the study. These documents were analyzed using content analysis and reviewed from the social and economic aspects qualitatively described. The result shows that the review indicates that 6 (six) fisheries businesses can provide multiple effects namely lobster aquaculture, seaweed farming, crab processing, fish head waste treatment, and salt farming have the opportunity to create multiple effects, meaning that the six businesses can create alternative livelihoods that can has an impact on improving the household economy.
