Abstract

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.

Abstract

The electrical energy of solar power plants which integrated into the networks depends on the intensity of solar radiation. However, some solar power plant areas there are still present trees and buildings around it that can partially cover the surface area of ​​the solar panel (partial shading). This study aims to investigate the effects of solar radiation variability due to several partial shading conditions on the 1 Wp solar cell output power. Based on observations from 10:00 to 14:00, the open-circuit voltage and short circuit current in solar cells decreases with increasing intensity of partial shading. The greater the partial shading of the solar cell, the lower the power output will be. The half partial shading effect of the total solar cell area resulted in a power reduction of 88.2%. A quarter of shading causes a decrease in the output power of solar cells by 75.6% compared to the power output under normal conditions. In addition, the increase in the temperature of solar cells resulted in a significant decrease in the open-circuit voltage.

Abstract

The greenhouse system works by utilizing solar thermal energy. It has a deficiency because it depends on weather to get maximum solar thermal energy. This deficiency can interfere with the drying process of plantation products, especially gaplek. Therefore, biomass furnace is added to overcome the dependence of solar thermal energy. The result of the proposed hybrid dryer system can control the temperature below 60℃. Moreover, the humidity can reach a minimum point of 60% while the temperature is 57℃. Those results show the system can give nomerous dry air to the dryer room because the greenhouse system is equipped with an exhaust fan. Thus, gaplek can appropriately dry according to the desired grade. Then, the cost of operating the proposed hybrid drying system is inexpensive, which is Rp 158.194,65 per year.
