Abstract

One of the metal welding processes required by the manufacturing industry is gas arc welding (GMAW). The welding process that is capable of transmitting large amounts of heat at high speeds is gas electric welding or GMAW (Gas Metal Arc Welding). The design mechanism for the movement of the X and Y axes in the development of GMAW welding holders uses the stages of finding ideas, studying literature, identifying problems, designing, making tools and testing machines. The purpose of this study was to design a mechanism for moving the X and Y axes in the development of an automatic GMAW torch holder machine and to calculate the machine elements in the development of an automatic GMAW torch holder machine. The process of designing and constructing the movement of the X and Y axes in the development of an automatic GMAW welding torch holder machine is carried out with a design procedure that is used as a reference in solving problems. The track shaft uses chrome steel with a diameter of 25 mm and a length of 800 mm, Linear bearings use type SCS25UU with an inner diameter of 25 mm, Linear rail shafts use aluminum alloy material with a diameter of 25 mm which is used to support the end of the track shaft, Ballscrew uses the SFU 2005 type with a size of 3/4 inch which is equipped with a ballscrew nut and also a nut housing, Bearing block uses a UCP type with a diameter of 20 mm, Flexible coupling measuring 5 mm to 10 mm is used to connect the drive screw with the stepper motor, The stepper motor is used as the main power to drive the drive screw type Nema 17 (17HD48002H-22B) with the specifications Step Angle: 1.8o, Rated Current: 1.5 Ampere, Voltage : 2.7V.

Abstract

The vehicle's suspension system have function to reduce vibrations from the shock between the wheels and the road. Previous research discussed the simulation of spring loading with material variations. This research focuses on the design and analysis of springs that will be used in Electric Motorbikes (SEMOLI). Spring analysis between cast stainless steels and carbon stainless steels is done by calculating displacement transmissibility. The analytical method used is the SDOF harmonic method to determine the system response. The results of the analysis are considered for the selection of springs by determining the displacement transmissibility and the response of the suspension system. The results of the analysis of the characteristics of cast stainless steels and carbon stainless steels for active springs 6, 7, and 8 at speeds of 10 km/hour, 20 km/hour, 40 km/hour, 80 km/hour showed a decrease in displacement transmissibility. Characteristics for stainless steel material at steady state condition with active spring 6 is 0.3 second, while 7 and 8 are 0.25 second. The characteristics of overshoot for cast stainless steel material with active spring 6 are 55.3%, 7 are 52.7% and 8 are 50.3%. Stainless steel material has the characteristics of overshoot on active spring 6 is 55.8%, active spring 7 is 53.3%, and active spring 8 is 51 From the characteristic analysis, the best material obtained is cast stainless steel with a smaller displacement value dan good respon.

Abstract

Bondan Hamlet is a hamlet in Kampung Laut District, Cilacap. One of the community's problems is the lack of clean water and the PLN electricity network. In 2020, a desalination facility named Sidesi Mas will be built in Bondan Hamlet with a capacity of 240 liters/hour and using the reverse osmosis principle. The energy source for desalination uses a solar power plant (PLTS). Desalination management requires economic analysis, especially in determining the selling price of desalinated water. The cost of producing desalinated water can be calculated using the Cost of energy (CoE) value of the PLTS or the costs incurred to produce electrical energy per 1 kWh. To get the PLTS CoE, this article discusses a simulation to analyze the performance of PLTS desalination systems with Homer software. Homer performs analytical calculations based on a location input, solar energy potential, capacity, and costs of PLTS components as well as electrical load data. The simulation results show that PLTS energy production is 535 kWh/year, the CoE value is IDR 21,975/kWh and the production cost for producing clean water is IDR 183.13/liter.
