Abstract

Post harvest handling and treatment of agricultural prodz~ct isextremely important in maintaining all of the possible qzralify of the prodzilrct. Most of the product needs to be handled and treated at low temperature. Duly. a cheap and easy-to-handle cooling facility is very important to be provitied nearer to producer's/ farmer's location. The objectives of the experiment were to design and evaluate the performance of an evaporative cooling system, uwd to develop a simulation model for predicting the performance and temperature distribution inside the storage room. Experimental data showed that the performance of the design was fairly good and acceptable. The cooling system could keep the temperature of product under ambient temperature, although the optimal temperaturecouldn't be reached. Performance of the design could be increased by improving the performance of nozzle, fan and the insulation system of the storage wall.

Abstract

The yield of "Gogorancah" or gora (dry seeding rice cultivatiorl)system is affected by the availability of soil moisture in the root zone during ils growing season. This paper is subjected to evaluate Jluctuation of soil water condition on gora system based on water balance analysis. Different planting schedule makes variation of the soil water fluctuation. Simulation for the best time seeding scheduling for "gora" was done by using 10 types of schedule and the result showed that yield of timeseeding in November 5-th was better yield than yield in October. Throuh field experiment which carried out for this study, it was proved that gora systeni save water at least as much as 250 mm/Ha/season or 2500 m3/Ha/season forthe land preparation water demand. The maximum water saving occured when gora syten~ is applied for November planting schedule which rice was cultivated as rainfed method, however, the yield is better than planting in October.Key word: gogorancah system, planting schedule, water saving.

Abstract

The objective of this research is tojind out the best temperature, lime and handling method for black tiger shrimp transportation with dry system. Anesthesis method was applied in this research by adopting gradual cooling ut the rate of 5"Cper hour. Anesthesis was done at various temperatures ( I Y, 17, and 15°C) and time (10, 15, and 20 minutes) with temperature in puckuge 17°C. The result showed that the survival rate of black tiger shrimp was affrcted by anesthesis temperature, but not by the time of cooling at the criticaltemperature. The optimum temperature for anesthesis was 15°C with the optimum length of time was I0 minutes. Meanwhile the optimum temperature for transportation was 17°C. gave the highest survival of the black tiger shrimp (Penaeus monodon Fab.).Key words : Black Tiger Shrimp, Dry Transportation System

Abstract

Banana is a potential commodity to gain foreign currency since its export has tended to increase yaer by year. Postharvest handling of banana is very important in order to maintain high quality of the products. Artificial ripening is one method applied to control the rate of ripening and in the other side to guarantee the uniformity of quality. Teperature in the ripening chamber plays an important role since it directly influences respiration rate of the products. This research is aimed to apply fuzzy control to regulate the temperature, which is set in order to get better quality of the product. Yhe objective of the fizzy control is to set the temperature into 4 (four) decreasing steps : 1) 24"C. 2)22.5"C 30 21.5 "C and 4) 24 "C each for 24 hours. Respiration rate during these periods are 0.0866 ml CO2/kg/h become 0.06054 ml CO2/kg/h or 3.1716 ml O2/kg/h/ become 0.7016 ml O2/kg/h.

Abstract

The research to evaluate perfornlance of grain cleaner APB-MI was conducted in the Research Institute for Maize and Other Cereals tit the beginning of 1998. Five engine circles were tested: 1200, 1350, 1500, I650 and 1800 rpm with three replications. Bisma variety was used us maize grrrin with 13% moisture content (wet basis) and for each replication the amount was 25 kg. The results showed that power transmission efficiency was at the average of 95.0% on the strainer and 94.2% on the blower. Fuel conszrtnptionwas at the rate of 0,81 //hour with average cleaning capacity of 598 kg/hour.

Abstract

This paper proposes a method for controlling groundwater level in order to maintain a certain desired height by using a simple fuzzy control system. The control signal is determined by evaluating the state of water surface height deviatioh from the desired height on a 4 quadrant phase plane. The control signal is then used to determine the number of drainage or irrigation pumps, which must be operated. Simulation using actual datafrom the jield shows that the proposed method is very effective to maintain the desired height of water surface. This method is very simple, therefore it can be easily implemented using a personal computer or a microcontrol/er, or up-loaded to a P LC (Programmable Logic Controller).
