Judul: Formulasi kebijakan sistem pengolahan sampah perkotaan berkelanjutan
Abstrak: Solid waste is still considered as worthless goods, so that it is still causing many problems. The purpose of this study is to formulate a sustainable urban waste management policy. The study was conducted in DKI Jakarta. The research is devided into four stages of analyses which include the availability and needed of land for a solid waste treatment, waste treatment technology optimization analysis of environmentally friendly, multi-criteria evaluation and policy analysis. Indonesia has many waste management policy, but not synergize together and not yet operational. Solid Waste management in DKI Jakarta has led to efforts to minimize waste, and waste reduction programs integrated between recycling, composting, combustion (incineration) and waste disposal system with a system of sanitary landfills, and will be pursued to zero waste program. DKI Jakarta needs to improve management efficiency and improved quality of service to the community, one with separation of regulator and operator functions, but managed by one institution to improve its performance and to cover the financing gap, ideally to cooperate with the private sector. The result of regression analysis shows a significant effect of economic growth in waste generation and characteristics. Increased in prosperity will increase the amount of inorganic waste, and lower amount of organic waste. Increased inorganic waste will increase the calorie content which is more beneficial if done with incinerator waste to energy (WTE), while providing the understanding that the waste is a resource that can be utilized as an energy alternative to electricity. Production of electricity from WTE incinerator is influenced by the calorie content, and type of waste. WTE incinerators have the advantage in processing speed and the required land area, but WTE incinerator required high initial investment. The result of CBA analysis shows that WTE incinerator is more expensive, but it is the most cost effective in the long term (25 years). The variables have a very strong influence on the cost of processing waste is waste transportation costs. In the context of environmental, sanitary landfill waste treatment system, which is placed far away from services area, can lead to a much larger greenhouse gases and generate leachate. The existence of designated land use and changes that are uncontrolled by DKI Jakarta complicate the placement of garbage processing unit. WTE technology or HRC which indoor system is more acceptable to local communities, compared to the open SLF. Incinerator technology is more efficient for processing large scale with a capacity of more than 500 tons / day, with the optimal point on the capacity of 3000 tons / day, which is supported by segregation. Organic waste treatment system is most optimal at high-rate composting system (HRC). WTE processing unit and HRC, should be placed in administrative of DKI. The sensitivity analysis shows that if the government would buy in a good price the electricity production and energy from solid waste, will raise the level of feasibility WTE incinerator system. Implementation of WTE incinerator technology, need to involve the private sector.

Abstrak: The rapid increase in population growth rate of Indonesia brings benefits to growth and development of the city became the center of economic activity, industrial, social and cultural consequences of the increasing social costs. One of the impacts that occur because of increasing population and consumption patterns of society is the increasing amount of waste that is a byproduct of human activity. Trash does not always lead to adverse impacts to humans, even garbage can be used as a valuable economic commodity. Recycling activities both through the reuse, recycling and composting by the community is beneficial because it can suppress the accumulation of garbage in the environment, and also economically beneficial to society itself. Besides the production of compost from organic waste derived from natural resources to be useful in restoring the natural nutrients are broken down can be used in aquaculture, especially in forest nursery plants, especially forestry and agricultural crops in general. Analysis of the participation rate in its waste management used Spearman Correlation Test. Financial feasibility analysis of Elegant Quality compost plant can be seen from the criteria of NPV (Net Present Value), Net B/C (Net Benefit/Cost), and IRR (Internal Rate of Return). Value of economic benefits by the city garbage scavengers obtained from the estimated volume of waste dauran materials obtained by scavengers multiplied by the value of selling. Primary data were collected through interviews using questionnaires and field observations. While secondary data obtained from literature studies that collect data that has become the archives for the manager, through the tracing information from the related institutions .. Community participation in district level Ciracas in waste management were categorized as high with the percentage (71.67%), this suggests a positive outlook, because the future of education levels tend to increase recycling and composting activities provide economic benefits and have a good opportunity to developed. The economic advantages of recycling activities on average Rp 892,259.41 per ton of inorganic waste. Business dauran waste materials will provide the average income of Rp 31229.08 / day. Composting business has a value of B/C 5, while the value of business acquired IRR of 44.47% lovely compost, compost operations conducted by the present value of benefits to be implemented because it provides an additional benefit or profit of Rp 24,480,229.42. The majority of landfill waste in East Jakarta came from residential 5300 m³/day (78.91%) and the market with a volume of 580 m³/day (8.64%). Amount of landfill waste is served that is equal to 83.43%, the remaining 16.57% of waste is not transported. Handling waste in the form of recycling (4-3R) in East Jakarta at 354 m³/day will be reduced at least 5.27% per day from the garbage of 6716 m³/day. While handling in the form of composting for 46 m³/day will reduce at least 0.68% per day from the garbage of 6716 m³/day. Citizen participation and scavengers in waste reuse of waste will reduce operational costs and can reduce the burden of cleaning service in transporting waste from TPS to TPA. And use of waste as compost made by the community have ability to

Judul: Pendugaan Karakter Sirip Kumpai pada Ikan Mas (Crypinus carpio L.)
Abstrak: Ikan mas kumpai (Cyprinus carpio var flavipinnis) adalah salah satu ras ikan mas yang sudah dikenal umum di Indonesia. Ikan ini biasanya dipelihara orang sebagai ikan hias di pekarangan rumah. Cirinya yang sangat menonjol dibandingkan ras ikan mas yang lain adalah sirip-siripnya yang panjang menjumbai. Steffens (dalam Kirpiohnikov, 1981) menyebutkan menyebutkan bahwa tipe sirip kumpai pada ikan mas merupakan hasil mutasi gen yang sederhana yang kemudian akan diwariskan kepada keturunanya.
