Pesantren Darul Bayan di bawah naungan pembinaan Yayasan Darul Bayan Pembangun Peradaban terletak daerah di Desa Cilayung Kecamatan Jatinangor Kabupaten Sumedang Jawa-Barat. Luas tanah yang dimiliki pesantren Darul Bayan sekitar 3000 (tiga ribu) meterpersegi, Di samping kegiatan kepesantrenan, Yayasan Darul Bayan Pembangun Peradaban membuat sekolah non formal (madrasah alquran) yaitu mulai dari tingkat SD sampai SMA, Jumlah santri kurang lebih ada 250 orang putra-putri, dua keluarga yang menetap, dan 20 orang guru. Pemenuhan energi listrik untuk kebutuhan sehari-hari di pesantren ini bersumber dari PLN dengan total daya sebesar 4400 VA. Biaya bulanan untuk penggunaan listrik rata-rata mencapai Rp 1.500.000 (satu setengah juta rupiah) tiap bulan. Biaya sebesar itu tentu sangat memberatkan, sebab tidak semua santri berkecukupan untuk membayar sumbangan pembinaan pendidikan (SPP) sebagai sumber biaya operasional bulanan. Oleh karena itu perlu ada upaya untuk meringankan biaya yang ditanggung pesantren. Masalah lain adalah keandalan listrik atau gangguan terputusnya saluran dan drop tegangan, serta sistem penerangan gerbang depan serta penerangan bilik di pesantren belum memadai. Untuk membantu meringankan biaya bulanan dan meningkatkan keandalan kelistrikan, maka dipasang Pembangkit Lisrik Tenaga Surya (PLTS). Sistem tersebut meliputi panel sel surya (gabungan beberapa modul sel surya), baterai, inverter, monitoring-kontroler, saklar, stop kontak, sensor photocell, dan pelengkap lainnya. Panel sel surya akan mengalirkan energi menuju baterai pada siang hari, pada malam hari lampu dapat dinyalakan secara otomatis maupun manual. Power House atau Pusat Daya PLTS akan dipasang di bangunan utama pondok pesantren, sehingga pemantauan PLTS akan lebih mudah.

Hydroelectric power plants often make use of tunnels to redirect the flow of water to the plant power house. Such tunnels are often flooded and can span considerable distances. Periodical inspections of such tunnels are highly desirable since a tunnel collapse will be catastrophic, disrupting the power plant operation. In many cases, the use of Unmanned Underwater Vehicles (UUVs) equipped with mechanical profiling sonars is a suitable and affordable way to gather data to generate 3D mapping of flooded tunnels. In this paper, we study the resolution of 3D tunnel maps generated by one or more mechanical profiling sonars working in tandem, considering synchronization and occlusion problems. The article derives the analytical equations to estimate the sampling of the underwater tunnels using mechanical profiling sonars (scanning sonars). Experiments in a simulated environment using up to four sensors simultaneously are presented. We also report experimental results obtained by a UUV inside a large power plant tunnel, together with a first map of this environment using a single sonar sensor.

Several fish species that spawn in lotic habitats have a larval-drift phase which is a major determinant of their reproductive success. The main objective of this study was to compare seasonal, diel, longitudinal, transverse, and vertical variations in rates of lake sturgeon (Acipenser fulvescens), Stizostedion spp., Catostomus spp., Moxostoma spp., quillback (Carpiodes cyprinus), and mooneye (Hiodon tergisus) larval drift in Des Prairies River (DPR) near Montreal (Quebec), which is one of the major lotic spawning habitats of the St. Lawrence River system. Larval sampling was conducted in the spring of 1994 and 1995 for the six taxa, and on a more restricted basis for lake sturgeon in 1996–1998, using drift nets set at several transects, stations, depths, and periods of the day, along a 19 km long section of river beginning ca. 2 km downstream from the DPR power house. For all taxa except lake sturgeon, peak larval drift occurred ca. 1 week earlier in 1995 than in 1994. The sequence was very similar between years, beginning with Stizostedion spp., followed by Catostomus spp., then lake sturgeon, quillback, and mooneye drifting simultaneously, and finally Moxostoma spp. Generally, for all taxa except quillback, whose multimodal drift pattern suggests intermittent, prolonged spawning, larval-drift profiles showed one major seasonal mode, which was observed simultaneously at all transects. For all taxa except quillback, drift rates peaked between 21:00 and 03:00 and were minimal during daylight hours. Lake sturgeon and Stizostedion spp. larval drift rates decreased radically from the most upstream to the most downstream transect, suggesting that both taxa spawn mostly in the vicinity of the DPR power house. More studies are required to explain this longitudinal decline in drift rates, particularly for lake sturgeon. The other taxa showed longitudinal variation in larval drift rates, suggesting that they spawn near the DPR power house and (or) in the Île de Pierre Rapids, ca. 12 km downstream. At all transects, larval drift rates for the six taxa were generally higher in the right half (Montreal) of the river, suggesting that eggs are deposited mostly in this part of the river at the two major spawning areas and that larvae tend to remain in the same general corridors during downstream migration. For all taxa, though to a lesser extent for lake sturgeon, nocturnal drift rates tend to be higher near the surface than at mid-depth and near the bottom, the reverse situation being observed for diurnal drift rates.

Comparative effects of effluents from six major industries viz. Diesel Power House, Hetaunda Iron and Steel, Hulas Wire, Himalaya Soap and Chemicals, Leather Industry, Shah Udyog and sub-metropolitan Sewage of Biratnagar on germination and seedling growth of rice and black gram were studied. Effluent of Himalaya Soap and Chemicals showed toxic lethal effect on both the test crops. On germination rice remained more sensitive and susceptible to the toxic effects of industrial effluents but black gram proved to be more tolerant. Effluents of Diesel power House and Shah Udyog remained toxic for seedling growth of black gram as their effects were significant while Leather Industry effluent showed toxic effect on rice for germination as well as seedling growth.

Abstrak - Air merupakan sumber daya alam yang sangat berpengaruh bagi berlangsungnya kehidupan mahluk hidup. Salah-satu pemanfaatan air adalah sebagai sumber energi Pembangkit Listrik Tenaga Mikro Hidro (PLTMH). Dengan adanya bangunan PLTMH, akan mempengaruhi ketersediaan debit air di sungai Cikandang bagi kebutuhan lahan pertanian. wilayah lahan pertanian yang terpengaruhi PLTMH berada diantara pintu pengambilan air sampai Power house. Hal ini perlu adanya imbangan neraca air antara ketersediaan debit air sungai Cikandang, kebutuhan debit air PLTMH dan kebutuhan debit air lahan pertanian. Dalam penelitian menganalisis imbangan neraca air antara ketersediaan dan kebutuhan, digunakan data curah hujan dari 2 stasion yaitu stasion Cirompang dan Pamegatan serta data klimatologi Garut dari stasion Legok Pulus. Dengan metode Mock untuk pengolahan data yang menghasilkan data debit andalan ketersediaan dan perhitungan kebutuhan debit irigasi dengan mengambil skema pola tanam sebagai acuan kebutuhan debit air. Dari hasil analisis didapat debit andalan setengah bulanan sungai Cikandang dengan rata-rata sebesar 25,86 m³/det, Kebutuhan debit air terkecil untuk lahan pertanian adalah 0,051 m³/det dan terbesar adalah 1,616 m³/det, dengan kebutuhan PLTMH sebesar 16 m³/det. Disimpulkan bahwa dengan adanya PLTMH, kebutuhan air bagi lahan pertanian tidak terpenuhi. Perlu adanya peninjauan kembali dalam pengelolaan air bagi kebutuhan PLTMH Cikandang 1.
