Judul: Techno-economic analysis of micro hydro at energy self-sufficient village of Kampung Lebakpicung, Hegarmanah, Cibeber, Lebak, Banten Province
Abstrak: Model of Energy Independent Village based on micro hydro has been implemented in Kampung Lebakpicung, Hegarmanah, Cibeber, Lebak, Banten Province. This area located directly adjacent to the National Park area of Halimun Salak Mountain. Three main issues have been proposed in the development of energy independent village based on micro hydro namely providing the electricity for local community, developing economic productive using the idle electricity as well as coserving the forest area near village through reforestration. All of three issues have been running well since 2 years ago and this program was strongly supported by local community. Institution based on the local community initiative has also been developed to take responsibility on the sustainability of micro hydro project. This institution has responsibility to run the operational of the micro hydro and to develop the utilization of idle electricity during day time for productive economic activity for local community. The objectives of this study were: 1) to analyze cost of electricity produced by micro hydro. The cost analysis includes kW of electricity could be generated and the price per kW which was based on the operational cost and maintenance cost, 2). to determine the energy cost must be spent by households before and after micro hydro project. Maintenance and operational cost was analyzed in order to consider the cost must be paid by each household. The study was focused on the collection of data i.e. social economic, potency of electricity, technical data of micro hydro. It was found that the potency of micro hydro power plant was 25-74 kW. The cost of electricity from micro hydro power plant was Rp 1.015/kWh. This price was higher than that price of electricity supplied by National Electricity Company with subsidy scheme of 450 Watt, i.e Rp. 415/kWh. The price of electricity that paid by the community was Rp. 239/kWh. If it was assumed that initial cost for installation of micro hydro power plant was under scheme of grant through CSR (Corporate Social Responsibility) of Natioanal Electriocity Company (PT PLN), it was resulted the (nett present value) NPV was Rp. 16.578.189,- at year of 20, payback period at year between 15 to 16. Net B/C was 1,1 and Gross B/C was 1,07 with IRR at 11 percent. BEP of electricity produced by micro hydro power plant was 162.744 kW/year. Utilization of the idle electricity produced by micro hydro power plant at Kampung Lebakpicung during day time could be considered by installing the small scale coffee processing unit.

Judul: . Analisis Ekonomi Pembangunan Pembangkit Listrik Tenaga Mikrohidro Cisaat Di Desa Puraseda, Kecamatan Leuwiliang, Kabupaten Bogor
Abstrak: Pendistribusian listrik kurang merata khususnya di Kabupaten Bogor. Masih banyaknya daerah terpencil yang belum terjamah oleh PLN khususnya di Kampung Cisaat Desa Puraseda Kecamatan Leuwiliang. PLN mewujudkan desa mandiri energi dengan membangun Pembangkit Listrik Tenaga Mikrohidro (PLTMH) yang didanai oleh anggaran CSR PLN. Hasil penelitian ini menunjukkan bahwa PLTMH pada prinsipnya memanfaatkan ketinggian dan jumlah debit air yang ada pada aliran air sungai. Kapasitas daya listrik yang dihasilkan yaitu sebesar 5,5 kW atau sebesar 5500 Watt. Masyarakat Kampung Cisaat mendapatkan keuntungan dengan adanya proyek PLTMH Cisaat. Biaya investasi tidak ditanggung masyarakat karena dana yang digunakan untuk pembangunan PLTMH Cisaat berasal dari Pemerintah Provinsi Jawa Barat atas sumbangsih PT. PLN sebesar Rp 193.504.000. Sehingga proyek PLTMH Cisaat dikatakan layak. Berdasarkan perhitungan pada skenario II diperoleh NPV sebesar Rp 14.388.589. NPV bernilai positif menunjukkan bahwa proyek pembangunan PLTMH Cisaat menguntungkan secara ekonomi. Pembangunan PLTMH Cisaat tentunya memberikan manfaat bagi masyarakat Kampung Cisaat. Masyarakat Kampung Cisaat tidak perlu membayar biaya pemasangan listrik dan pembangunan PLTMH tersebut dikarenakan mendapat dana hibah dari Pemerintah Provinsi Jawa Barat atas sumbangsih PT. PLN. Selain itu, keuntungan yang dirasakan masyarakat yang menggunakan PLTMH Cisaat yaitu tarif listrik yang lebih murah dibandingkan dengan listrik dari PLN. Manfaat sosial ekonomi dari keberadaan PLTMH Cisaat yang telah dirasakan masyarakat adalah meningkatkan pendapatan masyarakat, memperoleh pekerjaan sebagai operator PLTMH, dapat melakukan pengajian di malam hari, anak-anak dapat belajar di malam hari, mengurangi pengeluaran untuk membeli kayu bakar, dan mendapat hiburan dengan menonton televisi. Pembangunan PLTMH Cisaat menimbulkan beberapa dampak bagi masyarakat Cisaat. Indikator persepsi responden terhadap pembangunan PLTMH Cisaat mengenai dampak keberadaan PLTMH Cisaat mempengaruhi pada social capital.

Judul: Karakteristik Imago Jantan Ulat Sutera Liar Attacus atlas (Lepidoptera : Saturniidae)
Abstrak: This study aims to describe various morphometric parameters of male A. atlas moth, to found a correlation between the morphometric parameters and body weight on male moths, and to describe the reproductive system of male A. atlas moth. Male can distinguish from the female by comparing the antennae. The antennae of male is wider. There is a very strong correlation between the total body length and the body weight in linear equation Y = 0.875 X-1, 639 when Y is the weight in grams and X is the total body length in cm. Reproductive system of male A. atlas moth generally similer to B. mori reproductive system. Male A. atlas moth has reproductive system consists of a pair of testes, a pair of deferent duct with ampula ductus deferent, one spermatophore gland, one alba gland, one prostatica gland and one penis.
