Abstract

The amount of agricultural lands has been converted into residential land and industrial land since a lot of farmland in the mountains has been opened. Groundwater and river has been used to irrigate the agricultural lands. Farmers in the mountainous areas typically use his physical effort to get water from river to agricultural land. This causes inefficiency of working for farmers thus the agricultural productivity is not optimal. Owing the fact that agricultural land is far from the electricity resources (PLN) therefore a small capital farmer must use pump to irrigate their agricultural lands. Hence, farmers have to spend big amount of money to buy fuel to drive the agricultural pump engine. Thus, it is necessary to have a specific research on the availability of wind energy in order to mobilize the agricultural pump engine in the mountainous area. In this case, the authors have calculated and analyzed the potential of wind energy to drive the pump in the village of Sare, Aceh Besar. From the analysis it has been obtained that the average wind speed of 6,41 m/s with the diameter of rotor turbine about 3 meter result in 1005,26 watt of wind turbine power. This power can be used to power a 20 m head static pump, requiring 650 watt to provide irrigation for 19 hectare of agricultural land 7 hrs/day. HOMER and Epanet 2.2 software are used to conduct simulation for power system generation. The result of HOMER simulation shows the lowest NPC value of US$ 10.028 with the cost of energy (CoE) of USD 0.717 kWh. The system could produce electricity power in a year of 3.452 kWh and the working length of the generating power system is 15 years

Abstract

Fisheries as one of the pillars of the local economy in Aceh Province that had been optimally utilized. Catches especially during the harvest tends to be sold by the fishermen to other areas due to lack of knowledge of post-harvest handling. One of the post-harvest processing is the preservation of a cooling system is usually done with the use of cold storage box (cold box) at the Fish Landing Places (TPI). This study aims to get the length of storage time of fish that can maintain a temperature of 0°C to 5°C, by using the 3 kinds of cold storage box is made of wood material, fiber and styrofoam. From the results of testing two methods: the method of fish in the middle of the ice around it and the traditional methods used by the community found that containers with wood coated styrofoam insulation to maintain temperature of 2°C, while the  isolation box storage timber, fiber and styrofoam fish temperature exceeds 2.5°C. Wooden storage box covered with styrofoam has the most room temperature lower than the usualbox used by the community. This box is the ideal storage box, the construction is very simple.  The box is fully insulated by wood and styrofoam.

Abstract

The function of solar collector is to increase the air that consist of absorber, air duct and glass cover. One of the factors that affect the collector output temperature increased is depend on high temperature absorber. An absorber serves to absorb heat from the sun, and heats flowing air in the air duct above the absorber. The heating of the air pass/route is greatly influenced by the flow patterns inside the collector. In this study the authors examined the use of variations absorber on solar collector. There were four variations of The absorber; iron sand, gram iron sand, asphalt hotmix, and iron sand asphalt. The research method is intended to determine the value of heat transfer by radiation, conduction and convection. Dimension of solar collector was used 300 cm x 80 cm. The best variation of absorber was gram iron sand type at the most optimum intensity of sun at 12 a.m-2 p.m.

Abstract

This research aims to produce an effective heat sink with thermoelectric which is a semi conductor devices having several pairs of type P (positive) and N (negative) S content. Type P has a lower energy level while type N had a higher energy level. This tool, equipped with a heat sink as the heater, is mounted on a chamber to create a heat exchanger for a portable cooler box. Three types of thermoelectric modules were used with different fin types to find out the their effects on the temperature, T, and the rate of heat transfer, Q, inside the cooler box. The results shows that with the blood volume of 250 cc, the blood temperature can be decreased from 29 oC to 5.8 oC within 145 minutes. The ideal temperature for the blood storage ranges from 1 oC to 6 oC. Among the three types of fins that were tested, the most effective heat transfer was given by fin type no. 3, the cylindrical-shaped fins. The heat transfer obtained is 12.83 W/m2 oC. The lowest heat transfer was given by fin type no. 2, which is a slot type, with heat transfer rate of 3.85 W/m2 oC.

Abstract

Aceh is one of the biggest milkfish (chanos-chanos Forsskal)-producing provinces in Indonesia and the production is increasing year by year. However, beyond that prospect, there are disadvantages of the milkfish which are able to be putrid easily and are not able to be kept for a long time. In addition, at the time of great harvest and the fish production is plenitude and less of the fish is in use that the price of the fish decreases sharply. The population of Aceh generally like to consume fresh and dried milkfish especially the people in the rural and highland. Based on the result of the previous research, the drying method which is done by putting the fish under direct sunlight is inefective as the sunlight is not perpetually present as expected. Even the quality of the product is low as the fish is contaminated by flies. In addition it requires large drying areas to produce large quantity fish. In this research, it is conducted eksperimental analysis and drying characteristic of the milkfish in the drying process by using drying equipment with gas fuel. The drying equipment used is the shelf type which is located in Thermal Engineering Laboratory, Mechanical Engineering, Engineering Faculty, Syiah Kuala University. The equipment consists of burning room, drying room and chimney. The weight of  milkfish model is 200 grams, 250 grams, and 300 grams. Based on the test result on the milkfish weighted 200 grams after the drying process, it can be seen that the content of protein 18,97 %,fat 3,75%, water 19,20% with the total drying process of six hour.
