Abstract

Indonesia is a tropical country with a relatively high air temperatures. Increasing the temperature of the air outside the building space will increase in temperature in the room due to the heat transfer. Increasing air temperatures will occur in the thermal discomfort in space, resulting in a decrease in the effectiveness of work in the room. Conditions the average room temperature in May-September, 2013 in Banda Aceh is 330C-350C between the hours 11:00-13:00 WIB. This temperature is outside the limits of thermal comfort standards. To improve work efficiency in a room, the air must be conditioned to meet the thermal comfort standard SNI mounting method as a simple means of heat exchangers. Especially in the room that do not use often like indoor halls, and other sports, for this case by using the air conditioning air conditioner is too large investment and operational costs. In this study assessed a replacement air conditioning system with cold air in the conditioned room.

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 perception, localization, and navigation of its environment are essential for autonomous mobile robots and vehicles. For that reason, a 2D Laser rangefinder sensor is used popularly in mobile robot applications to measure the origin of the robot to its surrounding objects. The measurement data generated by the sensor is transmitted to the controller, where the data is processed by one or multiple suitable algorithms in several steps to extract the desired information. Universal Hough Transform (UHT) is one of the appropriate and popular algorithms to extract the primitive geometry such as straight line, which later will be used in the further step of data processing. However, the UHT has high computational complexity and requires the so-called accumulator array, which is less suitable for real-time applications where a high speed and low complexity computation is highly demanded. In this study, an Accumulator-free Hough Transform (AfHT) is proposed to reduce the computational complexity and eliminate the need for the accumulator array. The proposed algorithm is validated using the measurement data from a 2D laser scanner and compared to the standard Hough Transform. As a result, the extracted value of AfHT shows a good agreement with that of UHT but with a significant reduction in the complexity of the computation and the need for computer memory.
