Abstract

The purpose of the research are determine acceptance criteria the specimen based on ASME standard. The research used mild steel materials with hardness 220 HVN with sized 30 cm x 20 cm x 1.2 cm then  SMAW welding process position of 3G buttjoint with rooting electrode LB 52U diameter 2.6 mm used current 70 Amper and voltage 380 volt, for Filler used LB 5218 electrode 3.2 mm with current of 80 Amper and voltage of 380 volts. The welding process influenced by many factor which cause failure. The method for inspect result of weld used Non Destructive Test Penetrant Testing (NDT PT) and used ASME standard for acceptance criteria. The test results showed the discontinuity of porosity on the surface of the welded product in specimen 1 is the largest rounded 5 mm at 233 mm distance so that based on the acceptance criteria of AWS standard, the welding result is accepted and the specimen 2 there is discontinuity at 233 mm with the size of 8 mm so that Otherwise rejected. This rejected result can be improved by gouging the discontinuity and then welded.

Abstract

Hazardous and toxic waste (LB3) is one of the environmental impacts that must be managed in the Republic of Indonesia in accordance with Indonesian Law No. 32 / 2009 on the Protection and Environmental Management Article 58. B3 is the residue of a business and / or activities that contain hazardous and toxic. Hazardous and Toxic waste generated shall be reduced in accordance with Article 10 of Indonesian Regulation No. 101 / 2014 on the Management of Hazardous and Toxic Waste. One sector that has a real contribution in donating B3 waste generation is the energy sector. PT Pertamina, which is engaged in the energy sector undertake efforts to reduce hazardous waste generation on the activities of pumping the fuel at the Balongan Fuel Terminal. The case studies conducted in Balongan. Starter activities that were previously used accumulator pose as hazardous waste to be modified. Reduced waste generation by Fuel Terminal Balongan by modifying the diesel engine starter system method with compressed air.

Abstract

Generally, wind energy sources in Indonesia's coastal areas is one of the potential sources of renewable energy (renewable energy resources) which are abundant, environmentally friendly and renewable. Savonius wind turbines can produce relatively high torque even at low wind speeds. Because it is very well developed to produce electrical energy. To get a large electric power, a large turbine construction is also needed which also certainly requires a large cost. For this reason, it is necessary to develop the dimensions of this wind turbine construction which is known as aspect ratio (Ar). The Ar that has been researched is the blade section, and other values. While the arch depth or the length of the blade arc in U -type is still likely to be researched. Therefore, it is necessary to do research on the U-type blade arc to get greater power than before. In addition to the experimental method with a prototype of the U type Savonius wind turbine with a number of 2 blades, a software-based simulation method will be carried out to analyze the air flow on the wind turbine blade. Parameters varied only with the aspect ratio of the arc length and blade cross section width, other parameters follow the previous research. This analysis will be a comparative data with experimental methods. The expected simulation results obtain the best aspect ratio (Ar) blade in capturing wind energy.
