Pengembangan Dan Tata Letak Fasilitas Pada Galangan Bengkalis Marine Fiber

Bengkalis regency is one of the regencies in Riau Province with the capital city of Bengkalis located on Bengkalis Island, separated from Sumatra Island. The total area of Bengkalis Regency generally work as fisherman. The need for fishing boats on the coast of Bengkalis Regency is very large, currently many fisherman have switched to using fiber boats. There are quite a lot of fiber boat users in Bengkalis Regency, especially in the Bengkalis Island area. Meanwhile, there are only two repair places for fiber ships, namely Bengkalis Marine Fiber and Laksamana Marine Fiber. Bengkalis Marine Fiber is the largest fiber shipyard on Bengkalis Island which accepts new shipbuilding and fiber ship repair for the Bengkalis Island area and it’s surroundings. However, due to the high demand for boat repairs by fisherman, sometimes shipyard owners are forced to refuse because they cannot fulfil it due to limited facilities at the shipyards such as the absence of a separate room between the shipyard and the workshop, the absence of facilities such as slipway dock, and the unorganized flow of material from the shipyard. And the unorganized flow of material from the shipyard. So it’s necessary to develop the layout and facilities at this shipyard in order to meet the needs of repairing fiber fishing boats on Bengkalis Island and its surrounding

Analisa Teknis Ekonomis Laminasi Lambung Kapal Kayu 3GT

The process of lamination of fishing boats using fiberglass, this lamination can reduce damage to wooden boats, besides that it can also extend the life of the ship. This study discusses technical and economic calculations for lamination of 3gt fishing boats with the aim of knowing investment costs, costs per trip, fishermen's income per year, and knowing the return on investment. In carrying out this research several stages were carried out, namely calculating the cost of building a ship then determining fixed costs and variable costs so that income was known then calculating profitability and payback period The results of the calculation of IRR and NPV obtained economic values as follows, From a comparison of typical inflows with initial investment capital with a discount rate of 6%, an NPV value of IDR 119,568,847 with an index of 0.1% is obtained. The results showed that based on the results of calculations using the IRR method with a discount factor rate of 7%, the ship is feasible to operate with an IRR value of 83.9% with an index of 13.99 (with a catch of 47 kg/trip). Because the current banking interest rate is 6% per year. Based on calculations in the 3rd year the occurrence of a Break Even Point (BEP) with a cash accum value of IDR 79,624,820,23

Rancang Bangun Dan Analisa Kondesor Alat Destilasi Serai Wangi Dengan Kapasitas 250Kg-300Kg/Proses

changes by using variations in water flow rate, temperature changes are The performance objective of this distillation machine is to produce a yield that is obtained in accordance with Indonesian National Standards (SNI). For this reason, the presence of a condenser can convert steam into water, resulting in a better oil yield than before. The data processing that I took used a table with variations in flow rate of 18 liters/minute, 15 liters/minute, 10 liters/minute, by knowing the tube temperature and shell temperature. in the output pipe. The results of the research show that the condenser design using 304 stainless steel material with shell dimensions of 50 cm, 120 cm high and 304 stainless steel spiral pipe material with a diameter of 0.5 inch produces temperature obtained. The best way is by using a flow variation of 18 liters/minute, a variation of 18 liters/minute experienced the highest temperature reduction from 99 C to 28 C. From the results of research that has been carried out using variations in water flow rate, the best temperature changes were obtained using a discharge variation of 18 liters/minute. The variation of 18 liters/minute experienced the highest temperature drop from 99 oC to 28 oC because the water in the citronella distillation condenser continuously circulated
