Abstract

The fuel price increase with the increase of the number of transportation due to the increasing numbers of the population. Indonesia with more than 200 million people in need of transportation fuels in the form of gasoline and diesel in large quantities. Currently the main source of transportation fuels derived from petroleum. Premium production in Indonesia is about 62 million barrels and production of about 87 million barrels of diesel fuel. The product does not include the use for other needs, such as lubricating oil, kerosene, avgas, as well as other materials. This is particularly worrying given the oil reserves are dwindling. One of the alternative energy for transportation fuels is biodiesel as a substitute for diesel fuel.The castor oil has potential to be used as biodiesel. Fusel oil is a sugar mill waste containing alcohol. The reaction between castor oil and fusel oil with natural zeolite catalyst klinoptilolite be referred to as alcoholysis reactions that produce esters. Castor oil and fusel oil mixed with zeolite powder klinoptilolite that previously had been heated in a separate place until it reached its boiling temperature. Three neck flask fitted with a thermometer, hoses trailer makers, heater, and the agitator on 100 rpm with 100 oC of temperature. Snapshot taken at intervals of 30 minutes each. Conversion reaction calculated by analyzing the levels of glycerol bottom layer by means asetin. Alcoholysis fusel oil and castor oil with natural zeolite catalyst klinoptilolite produce esters that are approaching the properties of diesel oil with a calorific value of 19 119 Btu/lb. Optimum conversion of 57 % was obtained in alcohol - oil ratio of 9.29 mgek/mgek and the addition of a catalyst as much as 2.56% of the weight of oil.

Abstract

This activity aims to provide guidance, training, and mentoring to help resolve problems faced by partners, including high operational costs of fish farming because of the high cost of factory-made pellets, limited understanding and knowledge of fish farming techniques, and limited access to business capital in groups of freshwater fish farming in village of Jerukagung Srumbung Magelang. In this activity, the use of semi-intensive farming technology was introduced and the introduction of mixer and fish pellet feed making machines technology were able to produce pellets independently for groups of fish farmers. Semi-intensive system farming techniques are proven to be able to increase productivity at a low cost to replace the conventional methods that have been done so far. The service program was completed in eight months, divided into three stages consisting of competency enhancement, technology development, and partnership development. The use of semi-intensive farming technology by applying good pond water maintenance techniques, selecting the right seeds, and optimal feeding techniques has been shown to increase fish production. High feed costs during the enlargement process which can reach 75% of the total cost can be replaced using pellet feed has made by group using local raw materials that are easily available in the surrounding area or environment, so as to reduce feed costs by up to 25%.
