Abstract

This paper describes an interdisciplinary research project to investigate the sustainability of off-grid Photovoltaic Energy Service (PVES) delivery in Indonesia. The paper describes results from the preliminary fieldwork undertaken in late 2002 and early 2003, more substantive fieldwork was carried out in 2005. The general objective of this research project is to understand how PVES can contribute to improving the life of rural Indonesian communities having no access to the electricity grid. It adopts an interdisciplinary approach that combines social and engineering perspectives to address sustainability issues. The I3A (Implementation, Accessibility, Availability, Acceptability) Sustainable PVES Delivery framework was developed to assess sustainability and was used to assess three off-grid PVES case studies in Lampung, West Java and Nusa Tenggara Timur (NTT) provinces. The overall objectives of the I3A framework are to acknowledge the interests of stakeholders, maximize equity, assure PVES continuity and institutionalize PVES by utilizing and enhancing pre-existing community resources to leave host communities with the capacity to meet evolving needs. A key conclusion is that, to be sustainable and equitable, off-grid PVES projects should be implemented in an institutional framework that provides sound project management and addresses PVES accessibility (financial, institutional and technological), availability (technical quality and continuity) and acceptability (social and ecological).

Abstract

The experimental investigation and simulation model approach were carried out to investigate the behavior of the fine particles to ad here on the layer of liquid on the wall in gas-solid two-phase flow. Polymethyl methacrylate having two different mean-diameters of 20 mm and of 50mm was used for measurement. By using continuous feeding sys tem, the fine particles were entrained and mixed with the air in the duct. Experiment for solid particle gas with two-phase flow in room temperature was carried out to make a clear turbulent effect for particle adhering behavior to wall side having a high-viscosity liquid layer. These phenomena were also investigated by the simulation model which represented the experimental condition for two-phase flow and using k- two equation models for turbulent flow. The experimental result showed that adhered particle quantity depends on particle feeding rate. The result of simulation model also showed the same tendency. The relation of the various particles feeding rate and capture rate were also described.

Abstract

Wind energy potential in Indonesia is about 450.000 MW. The Heritage Bogor Foundation (HBF) is trying to contribute the use of renewable energy by introducing wind energy technology. The project has been starting since 2003, to conduct a research and development of wind energy technology for water pumping/ irigation and village electricity. The designed windmill was made as simple as possible and used local materials to make it affordable. This paper described wind data collection in the targeted area, the development stages and the benefit analysis for villagers.

Abstract

Sumatera Selatan merupakan propinsi yang sangat padat akan sumber energi fosil yang terdiri dari minyak bumi, gas bumi dan batubara, disamping potensi sumber energi hidro yang mampu untuk pembangkitan listrik sampai 405 MW. Permintaaan akan energi listrik dari tahun ketahun terus meningkat dengan pertumbuhan sekitar 9 % setiap tahunnya. Oleh karena itu untuk memenuhi permintaan akan energi listrik maka diperlukan suatu perencanaan penyediaan pembangkit listrik yang memakai teknologi pembangkit listrik yang memanfaatkan sumber energi yang tersedia dan diprioritaskan memakai sumber energi fosil non-minyak. Pada tulisan ini akan dijelaskan jumlah potensi sumber energi fosil dan air di Sumatera Selatan, kebutuhan listrik serta strategi pemenuhan suplai listrik dengan pilihan teknologi pembangkit memakai sumber energi yang tersedia.

Abstract

Most of the existing coal fired power plants in Indonesia that have capacity of 400-600MW is designed using sub-bitumonous coal intake. This coal has a caloric value of 5,000 kcal/kg (a.r.). Considering the coal price of sub-bituminous tends to raise, some power plant have switched to use a low rank coal having a caloric value of 4,200 kcal/kg (a.r.). Indonesian Coal Index (ICI), in November, 2008 indicated that the coal having caloric value of 5,800; 5,000 and 4,200 kcal/kg (a.r.) are US$ 93, 68 and 41 per ton (FOB) respectively. Low rank coal utilization in the existing coal fired power plant that was designed for the sub-bituminous coal intake are reviewed both in technical and economic aspect and its impacts on the power plant performance.

Abstract

Solar drying provides an alternative to the use of fossil fuel. Solar drying system is one of the most promising applications of crop drying. However, there are problems associated with the intermittent natural of solar radiation and the low intensities of solar radiation. The problems can be remedied by the use of heat storage, auxiliary energy source, control system, larger surface collector and hybrid system. However, this will result in a high capital investment. Economic indicators such as cost ofmaintenance, payback period, internal rate of return can be used to calculate the economic of it application.This paper presents the experience in Malaysia on crop drying. We also present the performance of four solar assisted drying systems for crop drying using different collector types, (a) V-groove solar collector with cabinet dryer, (b) double-pass solar collector with porous media in the lower channel and a flat bed drying chamber, (c) Solar dehumidification system and (d) Photovoltaic-thermal solar drying system.

Abstract

Kesulitan mendapatkan minyak tanah dan gas menyebabkan banyak ibu rumah tangga beralih ke kayu bakar. Makalah ini menguraikan hasil penelitian alternatif bahan bakar yang lebih hemat, mudah didapat/dibuat, serta menampilkan hasil percobaan penggunaan bahan bakar tersebut dalam Tungku Hemat Energi (THE) untuk merebus air. Beberapa tungku hemat energi dibahas secara singkat. Bentuk THE S1 dan THE S2 mungil dan ringan sehingga mudah dibawa-bawa untuk promosi ke daerah yang jauh. Perhitungan produksi massal diberikan sebagai masukan dalam menghitung harga unit menyesuaikan kemampuan dan fasilitas di suatu industri lokal. Perhitungan pendanaan ini mencakup upaya penyebar-luasannya melalui pendidikan masyarakat dan training for trainers. Diharapkan THE hasil riset ini akan teraplikasikan dan menyebar dengan cepat menampilkan aksi nyata menghemat penggunaan kayu di alam agar pohon-pohon di sekitar hunian tidak cepat habis dan menghindarkan daerah yang luas agar tidak cepat menjadi tandus.

Abstract

Energi listrik di pabrik teh yang dievaluasi digunakan pada setiap proses produksi seperti pelayuan, penggilingan, fermentasi, pengeringan, sortasi hingga pengepakan. Dari hasil penelitian menunjukkan bahwa total konsumsi energi 1.702.975 kWh/tahun untuk memproduksi teh kering sebanyak 3.444.761 kg. Sumber energi berasal dari PLN dan PLTMH (Pembangkit Listrik Tenaga Mikro Hidro). Komposisi suplai energi dari PLN 29,56% dan PLTMH 70,4%. Biaya pembelian energi listrik dari PLN pada tahun 2007 rata-rata sebesar Rp. 1.232,12/kWh dan biaya energi PLTMH Rp. 264/kWh. Total biaya energi listrik (PLN + PLTMH) sebesar Rp. 458/kWh atau setara dengan Rp. 240/kg-teh. Konsumsi energi spesifik (KES) di pabrik teh yang dievaluasi tahun 2007 adalah sebesar 0,48 kWh/kg. Nilai ini lebih baik dari tahun 2005 (0,54 kWh/kg) dan tahun 2006 (0,52 kWh/kg). Jika dibandingkan dengan pabrik di luar negeri nilai KES pabrik yang ditinjau lebih baik daripada India (0,65 kWh/kg) dan Srilangka (0,52 kWh/kg) namun masih lebih tinggi dari Vietnam (0,41 kWh/kg). Nilai KES akan menjadi lebih baik yang berada pada kisaran 0,5 kWh/kg apabila pabrik dioperasikan pada kapasitas produksi minimal 225 ton per bulan.
