Abstract

Milling was done to refine food materials to be powder with a certain sieve size in order to be more easily processed into other products. The purpose of coffee beans milling was to refine the beans into coffee powder with a certain sieve size in order to be easily brewed and gives the more optimal sensation of taste and aroma. This research was aimed to design, make, and evaluate the flat burr mill type of bean grinder on robusta cofee bean. The bean quality evaluated was the effective capacity of grinder mill, lost bean persentage, and economical analysis. The results showed the effective capacity of flatt burr type grinder was 5,00 kg/hr and the lost bean persentage was 1,112%. Based on economical analysis, the cost of robusta coffee bean milling was Rp.1.074,25/kg, break even point 2.748,9 kg/year, net present value (NPV) 16% was Rp.6.147,25 ,NPV 20% was Rp.5.397.751,98, and Internal Rate of Return (IRR) was 52.81%. Keywords : Coffee, flat burr mill, grinder, rotor, stator.

Abstract

Evaluation of the performance of irrigation system is one way to describe the circumstances and characteristics of an irrigation system. This study aims to evaluate the performance of operation and maintenance of Bandar Sidoras irrigation system. Some of the indicators used to determine the performance of the irrigation system were: functional performance and network infrastructure of irrigation, water sufficiency level, the level of accuracy of the provision of water, management of government institution, the availability of fund, human resources and farmer institutional performance. The results showed that the level of accuracy was very appropriate water supply, the management of government institution was very good, the farmer institution performance was very good each with the value of 4, functional performance and irrigation network infrastructure was well, the adequacy of water was sufficient, the availability of funding was adequate , and human resources were adequate each with the value of 3. in general, the performance of operation and maintenance of the Bandar Sidoras irrigation system categorized very well with a value of 3.36. Keywords: Evaluation of the performance, operation and maintenance, irrigation system, Bandar Sidoras

Abstract

agricultural waste. One of  utilization of the agricultural waste is tea waste that into briquettes as an alternative energy to replace fuel oil and gas, as well as a raw material for the manufacture of activated charcoal. That is why the author made a cast to simplify charcoal briquette printing making process. This study used literature study, cast making, instruments testing and parameters observation. Parameters measured were was capacity, moisture content, ash content, heating value, economic analysis, break even point, net present value, and internal rate of return. The results showed the capacity was 2,907kg tool / h, average water content was 2,6%, average ash content was 6,357%, average calorific value was 5740,70 cal / g, cost was Rp. 25.750,46 for the first year, Rp. 25.453,35 for the second year, Rp. 25.354,45 for the third year, Rp. 25.305,08 for the fourth year, and Rp. 25.275,53 for the fifth year, the break even point 952,89 kg /year for the first year, 513,71 kg /year for the second year, 367,52 kg / year for the third year, 367,52 kg / year for the fourth year and 250,86 kg / year for the fifth year, net present value of Rp. 1.135.273.634,79, internal rate of return was 12,74%, its mean that this equipment was worthy to used. keywords: printing tools, charcoal briquettes, tea waste.

Abstract

The process in making soya bean to be soya milk is an interesting thing to know. This research was held to design, to construct, to test, and to analyze economic value of soya bean milk maker. The parameter observed were effective capacity, yield percentage, organoleptic’s test and economic analysis.Based on this research, it was summerized that the effective capacity of this equipment was 6,18 kg/hour. Yield percentage was 64,4%. Basic cost from first year to fifth year were Rp 2.082/kg, Rp 1.920/kg, Rp 1.866,4/kg, Rp 1.839,26 dan Rp 1.823,12/kg. Break even point was 350,85 kg/year. Net present value with 8% rate was Rp 127.554.735,4 and internal rate of return was 34,4%. Keywords: Soya bean, milk, effective capacity, yield percentage, economic analysis

Abstract

Knowing water distribution in soil is important as one of the reason for irrigation. This research was purposed to study water distribution in Inceptisol soil planted with soybean at 100%, 80%, 60% field capacity and its effect on soybean plant’s production. The parameters observed were the characteristic of the soil physics, field capacity, evapotranspiration, water distribution, dry weight of soybean plant and pods weight.The results showed that Inceptisol soil had sandy clay loam texture. The highest porosity was found at 6-10 cm depth i.e. 63,06%. The lowest porosity was found at 0-5cm depth i.e. 54,23%. Water field capacity was 47,7%(dry basis). Soybean plant evapotranspiration at middle growth phase was 1,97 mm/day and the last growth phase was 1,58 mm/day. The highest water level was found at 6-10 cm depth i.e. 20,58-32,49% (dry basis). The lowest water level was found at  0-5 cm depth i.e. 20,34-26,63% (dry basis). The dry weight of soybean plant at the middle growth phase at 100% field capacity was 16,51 g, at the last growth phase was 14,89 g and pods weight was 13,20 g. The dry weight of soybean plant at the middle growth phase at 80% field capacity was 14,23 g, at the last growth phase was 11,77g and pods weight was 10,78 g. The dry weight of soybean plant at the middle growth phase at 60% field capacity was 13,12 g, at the last growth phase was 10,97 g and pods weight was 8,76g. Keywords: Evapotranspiration, Field Capacity, Inceptisol Soil, Soybean Plant, Water Distribution
