Abstract

The design of several vehicles by changing the design of the vehicle body and household materials using composites has already been carried out in Indonesia using various methods and using natural materials that are easy to find. A unique motorcycle body design can give an attractive impression from the appearance of the motorcycle in use, seen from the new physical conditions with the image of a motorcycle that is easily engineered in such a way that it becomes an opportunity for motorcycle manufacturers to design motorcycle bodies with natural materials that can received potential market share. One of the natural materials that can be made or designed to be used as an alternative to composite raw materials as motor designs that are easy to find in the NTT region is one of them is palm fiber, whose use is still limited.

Abstract

Fish as a source of animal protein is a fishery commodity that is prone to quality deterioration and spoilage after the fish is caught, so it needs fast, precise and correct handling to keep its quality in the hands of consumers. There for it is necessary to have a process that extends the durability through drying. One drying alternative is to use a Solar Air Heater with an Ultra Violet (UV) Solar Dryer drying house by making a building made of transparent material that functions as an insulator so that the solar irradiation trapped in the building will increase its temperature. The accumulated heat is used to dry the fish. Sardines that have just been displayed are put into the drying chamber with various loads of 22.23 kg, 14.82 kg and 7.41 kg. The energy source for drying is from sunlight with the Solar Air Heater system. The results show that drying efficiency and thermal efficiency increase with the addition of drying load. The highest values ​​of drying efficiency and drying house efficiency occurred at the mass load of 22.23 kg of fish at 13.17% and 50.57% with the lowest specific energy consumption (KES) of 18947.421 kJ/kg. The average temperature and temperature difference both in the solar air heater and in the drying chamber increase with the addition of the drying load. This temperature increase increases the drying rate which can reduce the drying time.

Abstract

The research area located in Baliara Village, West Kabaena District, Bombana Regency, Southeast Sulawesi Province has the potential for laterite nickel minerals that are quite prospect for mining. This is supported by the exploration and modeling of ore bodies which is the initial stage for mining. Exploration activities include drilling activities at locations that are suspected to have prospective laterite nickel ore content and conducting sample analysis in the laboratory, to determine the estimated levels at the research site. Modeling of the ore body was carried out to determine the shape of the ore body of laterite nickel ore at the research site. The modeled ore body will be a reference in carrying out mining activities. Exploration activities begin with drilling at the research site. The number of boreholes taken is 105 boreholes with a distance between boreholes of approximately 50 meters. The depth of the borehole ranges from 4.2 meters to 32 meters from the surface. For laboratory sample tests, samples are taken every 1 meter depth from each borehole. Using the conventional method, namely polygon, the area of influence in the calculation of nickel lateri resources in the Charlie Block, the tonnase is around 1195594.9 tons. Using surpac software the tonnase magnitude on Block Charlie is 3279775.4 Tons.
