Metal stamping industry has Quick Die Change (QDC) as a form of Single Minutes Exchange of Dies (SMED) as an efficient production technique where the implementation depends on operator’s activities, clamping system, accessories type and position, etc. This QDC could apply to improve the process efficiency, control of inventory and reducing the cost. This research compared the traditional metal stamping process and QDC System (QDCS) of metal stamping. This research was using Focused Group Discussion (FGD), direct observation and experiments, conducted in a private metal stamping company in wider Jakarta region of Indonesia. It was observed that the QDCS significantly reduces setup time, storage space and the cost. The setup time and cost reduced to one third of the conventional and the requirement of storage decreased by 70%. In addition, QDCS reduces the waste significantly.
This research to design a smaller and easy to operate meatball maker machine. This design will simplify, speed up and minimize the energy expended in the meatball maker machine. Simulation of frame strength using Solidwork 2018. The simulation value of von Mises stress on the frame is with a maximum stress of 10,550,430.00 N/m2 and a minimum of 90,629 N/m2 with a yield strength of 250,000,000.00 N/m2. Displacement in the simulation of displacement is with a maximum value of 0.154 mm and a minimum of 0.000 mm. The value of the safety factor from the simulation results is 24. Static simulation results of the strength of the meatball printing machine frame using ASTM A36 Steel L 30 mm x 30 mm 3 mm thick with a load of 25 kg, the frame is able to withstand engine performance during operation.
Analysis of the design of this energy-efficient stove for distributing the results from the HHO (Hydrogen Hydrogen Oxygen) generator and turning this HHO into a fire. The purpose of this analysis is to determine the strength of the stove frame with the maximum load it can accommodate. This stove is made with a design and structure that is larger in scale with new innovations that combine metal materials and concrete materials where the two materials are combined to create a sturdy and strong stove structure, the structure of this stove is innovated from the stove in general. The result of the force diagram shows that the bending stress of the weld seam is smaller than the allowable stress of the material, namely: wb = 8, 03×10-3 180 N/mm2. Therefore the stove is safe to use.
One of the processed products derived from coconut that has great demand in the world of health and beauty industry is virgin coconut oil or known as VCO. Most VCO is processed manually using conventional methods with unhygienic plastic containers and placement in open spaces by the home industries. This research is to develop a VCO-fermented tank that was able to maintain hygiene and low temperature during the fermentation process by using SS403 and teak wood insulation as the main materials. This research carries on by comparing the fermentation process and results between the conventional method and the new VCO tank. 41% VCO is produced from raw coconut milk using a new VCO tank which is 5% higher than the conventional method. The VCO fermented tank produced more VCO and was able to maintain lower temperatures compared to the conventional method and also can be operated with less procedure order.
