Abstract

The Blumbang micro hydro power plant is a power plant utilizing hydropower that supplies electricity to the Blumbang area. The resulting supply is very large, around 30 kWh. However, it cannot be fully used by the surrounding society. So, it is necessary to do a feasibility study to increase the power capacity to determine supply and demand. This research aims to determine the community's supply and demand, which will impact the potential that can be taken by society.The method used is field observations, supply and demand observations, analysis of differences in supply and demand. The results that the feasibility of increasing the power capacity. It supplies generated from PLTMH Blumbang ranges from 24-26 kWh of the electricity demand of micro hydro power plant, 6 kWh demand electricity of micro hydro power plant and PLN 16 kWh. The Blumbang society's electricity bill has decreased with the Blumbang micro hydro power plant.

Abstract

The development of technology for the use of natural resources as fuel is increasing. One of them is theresearch of third generation biodisel. This technology utilizes microalgae as an environmentallyfriendly raw material which is also a renewable energy source for oil. Biodiesel from microalgaeespecially Spirulina sp. is one of the energy sources that can replace conventional diesel fuel whichhas potential for high lipid content. This study aims to develop a microalgae cultivation technology in anairlift photobioreactor by adjusting the light intensity of the LED lamp to obtain an optimal growth rateand increase the biomass production of Spirulina sp. The research was conducted on an intermediatescale using an airlift type photobioreactor with varying light intensity, namely 1600 lux, 2200 lux, and3200 lux. Each treatment was carried out three times for 14 days. Measurement of biomass weight wascalculated using the gravimetric method, by taking samples every 7 days. Based on the data obtained,the application of different light intensities to the spirulina sp. cultivation system will have an effect onthe final result in harvesting day 14th, specifically the weight of the biomass produced. The averageyield of biomass on day 14th with the best results was obtained at light intensity of 1600 as much as 623mg / 100 ml.

Abstract

Salah satu permasalahan yang cukup berat di Kota Bandung adalah sampah plastik seperti di Kelurahan Pajajaran, Kecamatan Cicendo. Sampah tersebut sebagian besar belum dikelola dengan baik sehingga menimbulkan kerusakan lingkungan. Salah satu yang sulit diatasi adalah sampah plastik nonrecycleable seperti label kemasan botol air mineral, pembungkus makanan ringan, styrofoam dan lain-lain. Sampah-sampah ini kurang ekonomis untuk didaur ulang sehingga dibuang begitu saja ke Tempat Pembuangan Akhir atau dibakar di pekarangan. Di sisi lain, ada jenis sampah plastik yang mudah didaur ulang tapi nilainya kecil jika dijual tanpa dicacah terlebih dahulu, seperti yang dilakukan di bank sampah Astana Eyang. Permasalahan ini bisa diatasi dengan teknologi pirolisis untuk mengolah sampah plastik nonrecycleable menjadi minyak sintetis, yang bisa digunakan sebagai bahan bakar mesin pencacah plastik recycleable. Tujuan program ini adalah membantu masyarakat mengelola sampah menjadi produk yang bernilai tinggi dan menghasilkan manfaat yang besar bagi mereka. Metode pelaksanaan diawali dengan survei ke lokasi bersamaan dengan pembuatan alat di bengkel. Setelah itu dilakukan kegiatan sosialisasi dan diakhiri dengan serah terima dan pelatihan terhadap operatordan warga masyarakat sekitar. Adanya program ini diharapkan mampu mengatasi masalah sampah dan meningkatkan pendapatan warga, serta bisa mendorong penerapan teknologi yang sama di lokasi lain di Indonesia.
