Abstract

Kelompok Tani Minyak Serai Wangi Berkat Yakin merupakan kelompok tani penggerak diDesa Balai Batu Sandaran yang mengelola industri penyulingan minyak serai wangi. Pengolahan serai wangi harus memperhatikan aspek efisiensi dan efektifitas agar mampu memberikan keuntungan yang maksimal dan meningkatkan nilai tambah pada serai wangi. Tujuan penelitian adalah menentukan nilai tambah dan kelayakan finansial usaha minyak serai wangi pada Industri Minyak Serai Wangi Berkat Yakin Desa Balai Batu Sandaran. Analisis data dilakukan dengan Metode Hayami dan parameter kuantitatif dalam analisis kelayakan finansial ditunjukkan oleh indikator seperti: Benefit Cost Ratio (B/C),Internal Rate of Return (IRR), Net Present Value (NPV) dan Payback Periods (PBP). Hasil analisis nilai tambah yang diperoleh dari hasil pengolahan serai wangi dengan bahan baku 25.000kg menjadi minyak serai wangi sebanyak 400 kg adalah Rp.3.080/kg. Sedangkan rasio nilai tambah produk minyak serai wangi adalah sebesar 84%, artinya 84% dari nilai output (produk minyak serai wangi) merupakan nilai tambah yang diperoleh dari proses pengolahan serai wangi menjadi minyak serai wangi. Hasil perhitungan analisis kelayakan finansial industri minyak serai wangi didapatkan NPV Rp. 1.635.698.925,-  IRR 37,60%,B/C Ratio 1,45, dan PBP adalah 3 tahun 6,5 bulan. Ditinjau dari aspek ekonomi, usaha produksi minyak serai wangi dapat dikatakan layak dan menguntungkan.

Abstract

Based on research conducted, liquid smoke coming from the husk and coconut shell containing 58-70% Methyl Ester as biodiesel-forming compounds. Then conducted research for the manufacture of methyl esters of liquid smoke based on differences in their boiling points. The purpose of this research is the development of tools producing liquid smoke, liquid smoke processing into biodiesel, biodiesel testing with the diesel engine and the determination of the proper blending between biodiesel. The method used in this study is a phase of making tools, raw material preparation, testing tools  for liquid smoke production, purification, separation of methyl esters and methyl esters testing by blending in diesel engines. Obtained from research conducted work capacity device of liquid smoke 1:22 kg / hour with a yield of 32.17%. Performance test  by blending biodiesel B10, B20, B30, B40, B50 and B100 with a 6.5 HP engine capable of running a diesel engine with performance that is not much different, more smoke clear, odorless and lighter engine speed.

Abstract

The quality of rubber processed materials, that is produced by the farmer is generally low and can be seen from their colour,  pollutants levels, foul odour and the very cheap price. To improve the quality of the rubber should be done both in terms of its treatment and processing equipment. The main objective of this research is to enhance and improve the quality of farmer's rubber processed materials by using natural coagulant which liquid smoke to agglomerate the rubber, and designing of rubber grinding machine. The component of rubber grinding machine including hopper, regulating entry materials, three rollers, pulleys and belt, outlet, gears, engine, regulating the thickness and chassis. In this research, the thickness rubber after grinding is 3-5 mm accordance with Indonesian National Standard rubber. Processed material rubber produced is white and no pollutants. The coagulant used was liquid smoke with a concentration of 10 -20%, where this addition affects the agglomeration speed of rubber and smelled slightly of smoke. The average rate of Feed is 48.58 kg / h, a capacity of the machine is 37.40 kg/hr and cost of operation is Rp. 650 / kg.

Abstract

West Sumatra-Indonesia has potential to plant coconut due to the coastal location, sunshine level with average temperature 27oC. Coconut is a very productive plant.  Coconut dehusking is one of the process that takes a lot of time and energy. Most of the farmer still using human manual labour with the help of tools made of iron or wooden crowbar that is mounted standing vertically with the blade facing upward about 80 cm from the ground. To increase the number of coconut products, it is designed the coconut dehusker machine. The main component of the machine were two rollers that rotate each other in opposite directions with each roller embedded iron-shaped nails that work to tear the coconut husk. Each roller has a different rotational speed. This machine has dimensions of 98 cm x 51 cm x 95 cm. Roller length is 50 cm and diameter 4 inches. The power source of the machine is a 2 HP electric motor, the speed was reduced by using 2 speeds reducer with the ratio of 1:20 and 1:30 respectively. From the performance test of this machine can dehusk 100 coconuts per hour.  The operational basic cost of the machine equal to Rp 129.89 per coconut (about 1 cent) and Break Event Point is 12.387 coconut per year from the result of the performance test. From the economic analysis machine can be concluded that the use of this machine is better when compared to human labour which has limitation to duration and capacity.
