Kampung Agrowidya adalah salah satu kampung percontohan untuk wisata agro berbasis pertanian dan perikanan. Kampung Agrowidya yang terletak di Rajabasa Jaya memiliki sistem bertanam hidroponik dan budidaya ikan tawar pada kolam terpal. Namun, kondisi pencahayaan Kampung Agrowidya khususnya pada malam hari masih sangat minim. Berdasarkan fakta ini dan hasil audiensi dengan masyarakat, maka dilakukan upaya pemenuhan kebutuhan pencahayaan jalan umum di Kampung Agrowidya dengan memanfaatkan tenaga surya. Tahapan kegiatan dimulai dengan pengukuran dan analisis tingkat iluminansi dan dimensi jalan. Hasil analisis menunjukkan bahwa kondisi pencahayaan di jalan utama Kampung Agrowidya masih berada di bawah batas yang direkomendasikan SNI 7391:2008. Dilanjutkan pemodelan menggunakan DIALux dengan tiga jenis lampu LED Philips BRP130, BRP052, dan BRP042. Hasil opsi pemodelan yang paling sesuai dan memenuhi SNI 7391:2008 adalah lampu LED Philips BRP130 dengan tinggi tiang 5 meter dan sudut kemiringan 15o dengan menggunakan suplai listrik dari solar panel 210 Wp dan media penyimpanan energi 140 Ah. Penyuluhan tentang penenarangan jalan umum tenaga surya dilakukan untuk membentuk kader masyarakat yang mampu memanfaatkan energi terbarukan khususnya energi surya. Hasil kegiatan pengabdian pada masyarakat ini memberikan hasil berupa instalasi penerangan jalan umum tenaga surya dan peningkatan pemahaman masyarakat Kampung Agrowidya tentang manfaat penerangan jalan umum tenaga surya.
Generally, the supply of heat energy is abundant in this world especially from direct solar radiation or combustion process activity. However, this energy is mostly wasted and discharged to the environment without recovery and re-utilization process. There is a potential utilization this heat to be converted to electricity using thermoelectric generator (TEGs). This technology device has an ability to convert heat to electricity by difference temperature from both surfaces. This device could prevent thermal loss to environment and optimize the system to generate electricity for small and micro scale power generation. This research conducts a literature review about identifying several potential object application or equipment as heat sources from solar energy or combustion activity combine with thermoelectric generator at low grade temperature that has been worked by previous researcher for past 5 years. Current status and working principal of thermoelectric generator is presented briefly. Several parameters such as working temperature range, potential output power, and efficiency system are described and presented. Then, some implementation challenge and opportunity development combination TEGs with each object applications are discussed and analyzed to produce recommendation for further research
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
