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

The need for a simple solution to derive the total heat loss coefficient, UL , is unquestioned as this reduces time to compute the performance of investigated system, especially in atmosphere when practicality is highly needed. This paper describes a simulation and comparison of several ways to obtained UL The assumptions used and the method are described briefly. The analysis of the result shows that the derived equation (10) applied for solar box cooker type HS is the simplest. The long field test has proved its simplicity and people can understand it easily in practice. This numerical experiment is provided for the readers to validate this simple equation as it can be a tool for the scientist who needs to transfer their knowledge to a wider education level in the context to popularize the application of renewable energy.

Abstract

Firewood in almost all rural areas uses firewood for cooking. Smoke exposure from firewood seriously affects the children's growth and the health of women, increasing woman burden and poverty. Its greenhouse gas (GHG) emissions contribute to global climate change. This is one of the greatest challenges of humanity. The CDM (Clean Development Mechanism) Solar Cooker Project in Sabang Islands and Badar city in South East Aceh was arranged to lay down a better energy path scenario for the future. Solar concentrator cookers "K14" and heat retaining containers named "Wonder box" will be transferred to the people. This project avoids 3.5 tonnes CO2 emissions per year per K14 and applies for a renewable crediting CER (carbon emission reduction) for 7 years period. The CER verification is described. Some views as a societal research finding within the CDM Solar Cooker Project Aceh 1 are described briefly.

Abstract

Electrification ratio of NTT is 28.7 % in 2008. Technical and economical assessments to investigate the possibilities to implement wind farm in East Nusa Tenggara (NTT) province is directed to contribute in the effort to raise the electricity ratio in this province. Some areas are having yearly average wind speed greater than 5 m/sec and the wind power density greater than 300 Watt/m2 . Wind farm is proposed to reduce local dependency to Diesel Power Plant (DPP) and to exerting an effort to reduce CO2 emission. The result of survey, Wind Energy Conversion (WEC) selection and simulation to get wind farmconfiguration for Oelbubuk, in South Central Timor (TTS) Regency in NTT is described. The evaluation of three different WEC having capacity greater than 250kW per unit and its formation are described. The assessment of electricity facilities of DPP in SOE city, its load profile in 2008 and the possible of interconnection to wind farm are described.
