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: Dampak Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) terhadap Sosial, Ekonomi, dan Lingkungan di Kampung Lebakpicung, Cibeber, Lebak, Banten
Abstrak: Peningkatan jumlah penduduk memicu peningkatan kebutuhan energi, tidak terkecuali energi listrik. Energi listrik tidak hanya dibutuhkan dalam beban besar, tetapi juga dalam beban kecil yaitu lingkup rumah tangga. Energi listrik tersebut seringkali belum dapat didistribusikan secara merata di Indonesia karena keterbatasan pasokan dan sulitnya akses distribusi. Kendala-kendala tersebut dapat diatasi dengan memanfaatkan sumber energi lokal yang tersedia di daerahdaerah yang belum mendapatkan pasokan listrik dari negara. Pembangunan Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) merupakan salah satu alternatif dalam memenuhi kebutuhan energi listrik di Kampung Lebakpicung. Dampak langsung dan tidak langsung dari keberadaan PLTMH dapat mempengaruhi kondisi sosial, ekonomi, dan lingkungan di Kampung Lebakpicung. Identifikasi dampak PLTMH terhadap kondisi sosial masyarakat dilihat melalui persepsi masyarakat terhadap PLTMH, perubahan pola nafkah, dan pranata sosial. Identifikasi dampak PLTMH terhadap kondisi ekonomi masyarakat dilihat melalui perubahan konsumsi energi, perubahan pendapatan bersih, dan hubungan antara pendapatan dengan biaya listrik. Identifikasi dampak PLTMH terhadap kondisi lingkungan yaitu dilihat melalui upaya reboisasi lahan kritis di sekitar hulu sungai Ciambulawung. Data yang diperoleh pada penelitian dianalisis secara deskriptif kualitatif dan kuantitatif dengan menggunakan program Microsoft Office Excel 2007 dan SPSS 16. Penelitian ini dilakukan di Kampung Lebakpicung, Desa Hegarmanah, Kecamatan Cibeber, Kabupaten Lebak, Provinsi Banten. Pemilihan lokasi dilakukan secara sengaja (purposive) dengan alasan Kampung Lebakpicung merupakan Model Desa Mandiri Berbasis Mikro Hidro di sekitar Taman Nasional Gunung Halimun-Salak (TNGHS). Pengambilan data primer dilakukan pada bulan Mei 2011. Pembangunan PLTMH memberikan berbagai manfaat kepada masyarakat, terutama listrik untuk penerangan. Dampak langsung adanya PLTMH hanya dirasakan oleh responden yang memiliki mata pecaharian sebagai tukang bangunan dan pemilik warung. Pembangunan PLTMH memberikan dampak terhadap kelembagaan agama, kelembagaan adat, dan kelembagaan formal di Kampung Lebakpicung. Koperasi “Bangkit Maju Bersama” merupakan kelembagaan formal yang terbentuk setelah adanya PLTMH. Setelah pembangunan PLTMH (tahun 2011), telah terjadi penghematan pada total konsumsi energi di Kampung Lebakpicung yaitu sebesar Rp 1.212.068/bulan dan telah terjadi surplus pada total pendapatan bersih di Kampung Lebakpicung yaitu sebesar Rp 5.963.985,023/bulan. Setelah pembangunan PLTMH (tahun 2011) diketahui terdapat hubungan antara pendapatan dengan biaya listrik. Surplus pendapatan akan cenderung diiringi juga oleh peningkatan biaya listrik. Kegiatan yang dilakukan setelah pembangunan PLTMH yaitu penanaman 1.000 pohon di lahan TNGHS dan 8.000 pohon di lahan masyarakat.

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.
