Abstract

Nabila Rusip is one of the IKM built Disperindag Pangkalpinang City which makes the traditional food of the people of Bangka became popular and famous. This success is inseparable from the role of Local Government of Pangkalpinang City which continues to encourage Nabila Rusip business with the provision of appropriate technology in 2015 in processing fish raw materials for the manufacture of rusip. However, at this time the machine can not be operated again due to operator error in using the tool. The purpose of science and technology for the community of the business group of the russians is to repair the fish pressing machine for the manufacture of rusip which was received by the partner from the Industry and Trade Office of Pangkalpinang City. The implementation method starts from inventorying problems, the process of repair and manufacture of machinery, assembly, testing and lastly provides a brief training on how to operate and maintain the correct machine. The results of this activity obtained the fish machine can be re-operated, productivity Nabila Rusip increase and the sale proceeds to increase.

Abstract

Betel nut palm plant is one of the many benefits and efficacy, especially seeds. Areca nuts are widely used as the main raw material in the process of making drugs, cosmetics, slimming, snacks, sweets, and coffee. Betel nut processing into betel nut is still constrained by the tool is still modest, are still using wood beams repose knife to split betel nut into two parts. To overcome these problems needed betel nut splitter machine with a capacity of 250 kg / h. This engine design is expected to help farmers during the process of betel nut processing into dried betel nut. The working principle of betel nut splitter machine originated from an electric motor that produces rotation is forwarded to the reducer and to the cutting blade associated with two gears. Betel nut is inserted through the insertion funnel towards the rotor has 4 channels / trench, and rotor spinning and crashing betel nut rotating blades reversed so the rotor besidesbetel nut split into two parts. Shaft rotation speed at the eye-piece and carrier rotor shaft is 9.32 rpm, the rotation speed is obtained from the ratio gearbox and pulley on the engine splitter ratio. With the machine is expected to help farmers to cultivate betel nut, so the work is lighter, faster and may prevent accidents. Shaft rotation speed at the eye-piece and carrier rotor shaft is 9.32 rpm, the rotation speed is obtained from the ratio gearbox and pulley on the engine splitter ratio.

Abstract

This time the need of transport's mode for the disabled leg is not maximized. To fulfill these need, we need the necessary transportation tools, one of the tools is a bike. However, the existing bike cannot be used for patients with leg disabilities. The purpose of this research is to design an electric bike wake for the disabled leg with movers using hand paddles and electric system. Bikes are made to be able to provide a low risk of injury while driving and can be used on any terrain. This research will be focused on the design and make electric bike frame for the disabled leg with brushless motor drive and battery charging via PLN's electricity. The stages of the research is the first stage of drafting the bike according to the list of needs. The concept design electric bikes are made with size 1270 x 850 x 1226 mm and uses three wheels. For the movers using brushless DC motors 350 Watt / 48 V with battery accu used 12V / 7 Ah combined series of 4 pieces battery and for manual use paddle power hand. The second stage of is the process of making electric bike. The third stage of is the process of testing an electric bike. Tests performed include testing the strength of the frame, tilt test and movers’s test on the bike. From the results of Static test performed that by loading 70 kg on the bike showed the bike suffered no damage and passed the test. In testing of stability with position of the front wheel facing upwards, downwards and sideways with make a tilt angle of 100. The test results revealed bike was not damaged and will not tip so the bike passed the test. For the test movers electric bike, the speed of electric bicycles from testing up to 20Km / h on a straight road for 1 hour and charging time for 3.5 hours using a charge battery 48V / 2A through voltage PLN’s source.

Abstract

Trolley is a means of moving from one area to another. A very helpful manual tool for moving goods, in order to facilitate the movement of an item to the destination. However, these activities will be hampered if the luggage is a lot and heavy. So the trolley will be made slightly different from the general trolley, namely in the form of a trolley that can be paired as a bicycle holder. This tool has a main frame that can be called for a load, the frame itself uses low carbon steel material in the form of a hollow box, namely St37 steel with a length of 188 mm, width 15x15 mm and thickness of 1.3 mm. In this study, to complete the analysis of frame strength using Solidworks Software, using a static simulation feature so that the stress value that occurs can be known. Solidworks is able to improve and validate performance and reduce the need for prototypes or costly design changes at a later date. The results of this study indicate that the trolley using low carbon steel material with a predetermined size is able to withstand the load of 30 kg.

Abstract

The welding procedure looks very simple but in practice there are many problems that must be overcome where in repairing it requires various kinds of knowledge, electric arc current and welding defects greatly affect the strength of the weld joint. he conducted a study to determine the effect of electric arc current on low carbon steel St 37 on impact strength. The test method was carried out by the charpy method using five (5) variations of amperemeter 160,180,200,220,240 with plate dimensions: 200mm×100mm×10mm and using a single V seam, with a welding position of 1G (groove). GMAW welding method. specimen dimensions 55mm,×10mm,×10mm,. So it can be concluded that the lower the electric arc current, the higher the impact price, and vice versa, the higher the arc current, the lower the impact value. The results of the highest impact value on an electric arc current of 160 from the Capping weld with a value of 0.92778 (Joule/mm²), and the smallest value is found in the result of the Root Pass weld on an electric arc current of 240 with a value of 0.09875 (Joule/mm²) .
