Abstract

Pemanfaatan air sebagai bahan bakar menggunakan teknologi HHO generator dan elektrolisa air membutuhkan peralatan yang komplek dan mahal. Alternatif lain adalah menggunakan kit pemecah air dengan memanfaatkan panas gas buang yang selanjutnya diberi nama Otoinfus. Penelitian ini bertujuan menguji pengaruh dari penggunaan Otoinfus pada motor bakar bensin terhadap laju konsumsi bahan bakar, emisi gas buang, torsi dan daya. Penelitian diawali dengan persiapan alat ukur konsumsi bahan bakar yang berfungsi untuk mangamati penurunan bahan bakar. Selanjutnya pemasangan Otoinfus, uji konsumsi bahan bakar, pembebanan pada berbagai kecepatan putar, uji emisi gas buang, dan pengukuran konsumsi air. Hasil penelitian menunjukkan penurunan konsumsi bahan bakar bervariasi berdasarkan putaran mesin dan penurunan signifikan (sebesar 20,46%) terjadi pada putaran mesin 3600 rpm. Penurunan senyawa gas buang signifikan terjadi pada gas O2 yaitu sebesar 63,99% dan minimum pada NOx yaitu sebesar 7, 14%. Penggunaan Otoinfus juga terbukti dapat meningkatkan torsi dan daya maksimum terjadi pada kecepatan putar motor bensin 2100 rpm yaitu sebesar 34,18% dan 33,93%  sedangkan pada kecepatan putar motor bensin 2400 rpm pemasangan Otoinfus tidak berpengaruh terhadap perubahan torsi dan daya.

Abstract

Water resources availability is a key that must be met in the paddy field extension due to water is needed for thegrowth of paddy. This study was to evaluate the potential of irrigation area for paddy field extension in TulangBawang, Lampung. The study began with the preparation phase, followed by field coordination, mobilizationteams, survey and investigation of the potential for irrigation area, processing and analysis of data field. Theresults showed that potential location of water resources in Tulang Bawang river and Pidada river with instantaneousdischarge ranged 1180-3775470 liters/ sec. Those water resources are located above the candidate sites and willbe used to irrigate candidates area varied from 74.39 to 1381.71 hectares. Driest month occurs in August about85.5 mm/month of rainfall while wet months in January about 353.33 mm/month of rainfall with annual rainfallranges from 2372 to 2539 mm/year.Keywords: irrigation, Tulang Bawang, paddy field extention

Abstract

Grain (Oryza sativa L) drying process is generally still done traditionally by direct sunlight. The drying process has several disadvantages such as it can only be done when sunlight is available, a longer drying time, a large area, requirement. An alternative that could be done to dry the grain in addition to using traditional drying was to use a grain dryer machines with do Wargi Mekar Farmer at Kerawang. There are several fuels that are used as heat sources for rice drying machines, one of them is firewood. This study aimed to measure the actual capacity of the wood-fired grain dryer, and also to analyzed the efficiency of drying and specific energy consumption to dry the grain. The research method used is descriptive analysis research method, namely data collection, data processing and data analysis. Research resulted that grain drying using a grain dryer as much as 761 kg.hr-1 . The yield of dry grain is 89.77%, and the value of weight loss is 10.33%. The moisture content of the material after drying is 13.06% wet basis. The drying efficiency in the process was 17.19% and the specific energy consumption was 15,318.24 KJ / Kg water vapor. Keywords: efficiency energy, grain drying, specific energy consumption

Abstract

Beberapa kelemahan mesin penyangrai William Eddison W600i antara lain  tekanan gas bahan bakar tidak terkontrol, dan sistem pengeluaran asap (exhaust) yang tidak optimal menghisap asap dan kulit sekam kopi pada ruang penyangrai. Permasalahan tersebut berimplikasi pada biji kopi sangrai yang masih mengandung asap (smoky). Penelitian ini bertujuan melakukan modifikasi dan uji kinerja terhadap mesin penyangrai William Eddison W600i. Metode yang digunakan pada penelitian ini dilakukan melalui pendekatan rekayasa untuk memodifikasi exhaust fan mesin penyangrai biji kopi. Data hasil pengujian mesin dianalisis secara deskriptif. Hasil penelitian menunjukkan rata-rata suhu pada ruang penyangrai sebelum modifikasi sebesar 217,11oC, kadar air 2,42%, laju penyangraian 0,09%/menit, efisiensi penyangraian sebesar 18,55, kulit sekam sisa penyangraian 4,6g, konsumsi bahan bakar 0,5 kg/jam. Sedangkan rata-rata suhu pada ruang penyangrai sesudah modifikasi sebesar 212,11oC, kadar air 2,44%, laju penyangraian 0,08%/menit, efisiensi penyangraian sebesar 18,36, kulit sekam sisa penyangraian 3,4g, konsumsi bahan bakar 0,5 kg/jam. Kata kunci : biji kopi, mesin penyangrai, modifikasi mesin

Abstract

Spinach chips is one of the snack products with the main ingredients of fried spinach using flour. The quality of spinach chips is influenced by the amount of oil contained in spinach chips. The use of spinner machine is proven to reduce or eliminate the oil content quickly and improve the quality of the product but the spinner machine available on the market can not be used to drain the oil contained in spinach chips because the rotational speed in the setting of more than 400 rpm can cause damage to spinach chips . This study aims to modify the spinner by lowering the speed of rotation and do the financial feasibility analysis of spinach chips production. The method used in this research is through the approach of engineering design and financial feasibility. The design approach consists of problems identification, formulation of modification concept, functional and performance test while some parameters calculated in financial feasibility analysis are: cost of production (HPP), net present value (NPV), benefit cost ratio (BCR), internal rate of return (IRR), and payback period (PBP). The results showed a decrease in rotational speed from 532.50 rpm to 258.18 rpm was proven to be able to remove the oil content on spinach chips and avoid the damage of spinach chips from 50% to no broken spinach chips. At production capacity of spinach chips 150 kg / month obtained cost of production amounted to Rp. 43,087 / kg. When spinach chips sold at market price Rp.50,000 / kg obtained NPV of Rp. 15,088,782/ month, BCR of 1.10, IRR of 12% and capital will return in the eigth month.
