Abstract

Trunan is one of the biggest tahu industrial centers in Magelang. Nevertheless, the number of tahu manufacturer in this neighborhood is decreasing as the result of the unreachable price of the raw material and the lack of sawdust, which is used as the fuel. On the other side, the industry also causes environmental problem since the liquid wastes, as the side effect of tahu producing process, commonly is simply littered to the waters. As the result, the waters become polluted as well as the groundwater which is indicated by the dirtiness of the waters and stinky smell. To help solving the above problem, we hold a research with objective to make use of tahu liquid wastes as an alternative fuel. Based on some researches, liquid wastes of tahu liquid wastes as an alternative fuel. Based on some researches, liquid wastes of tahu contain methane more than 50% that makes it possible to become the raw material of biogas energy. The method used in this research is engineering method (design activity) which is not routine, thus there will be new contribution either for the process and the product/protptype. The result of the research shows that to produce 1500 liter of biogas that fulfills the average need of a household it takes 100 kg of soybean per day. Hence, for each cooking process of tahu which needs 30.000 kg of soybean produces 283,8 m3 of liquid wastes per day, which then produce 442,650 liter of biogas. Afterward, to steam 100 kg of soybean it takes 3,93 m3 of biogas, while it takes 20 kg of sawdust. Every 100 kg of soybean takes energy which costs Rp. 40.000 for 3 times cooking process and each process takes 0,2 m3 of sawdust which costs Rp. 12.500. Therefore, the efficiency reach 61,1%. Moreover, beside used as fuel to cook, biogas can also be used for other need like lights.

Abstract

Micro-Hydro Power Plants (PLTMH) have been built in some countries in Indonesia as alternative ways to generate electricity for any regions which have no electricity from PLN. Electric energy generated by PLTMH are commonly used for loads such as electric motors, lamps, heaters, etc. This consumpsion will result in some power components appear, these are active power, reactive power and harmonics so the efficiency will be poor and finally the amount of power that used by the people will be smaller. In this research a device called current compensator is installed in parallel connection to the system to recovery reactive and harmonic power component. This compensator will inject current components that force the generator only supply active power compenent. This condition will increase the efficiency. The core of a current compensator is power converter that is implemented by high speed static switches. They are controlled automatically to adapt the real condition. Analysis and laboratory experimental works are done to validate.

Abstract

MOCAL is descendant product from cassava, which apply principal modification of cassava cell by microbe fermentation. MOCAL can substitute wheat flour in many foods, namely, noodles, bread, cakes, and other cakes at varying levels of substitution. The increase of wheat flour price encourages food processors looking for cheaper substitute materials, namely, MOCAL. In response to these trends, the Central Java government plans to develop 51 industrial clusters of MOCAL with plasma core model. Supports the plan, efforts should be made to improve the productivity of cassava farming. Because of the lack of high quality seeds, farm productivity of cassava in Central Java has not been optimal. Cassava breeding centers of government has released several high yielding varieties of cassava, but the propagation activities have not grown well. This paper provides an overview of the basic technology on seed propagation of cassava and institutional guidelines of cassava seed production. To support MOCAL industry, cassava seed supply should fulfill the six rights, namely the right varieties, the right quality, right quantity, right time, right place, and the right price. To produce high quality seeds, the seed propagation should follow the standard procedures of good cassava seed production, ranging from stage of selection and preparation of breeder seed, land preparation, planting, crop maintenance, harvesting, and post harvest handling. To fulfill the needs of seeds with a uniform quality in large amounts, the seed production units should apply the method of rapid seed multiplication, and developed in the institutional group of farmers. To ensure a sustainable supply of seeds as needed, there should be an inter-regional seed network. The development of seed production units should be a part of MOCAL Industrial Cluster Development Program, and all stakeholders should take a role in these affairs.
