Abstract

Passive design is a way to save energy through the passive use of solar energy, that is, without converting solar energy into electrical energy. the passive design relies more on the ability of engineers how the design of the building itself can "anticipate" external climate problems. In Indonesia as a tropical region, cooling systems and lighting systems are the largest contributors to building energy consumption, accounting for 24.7% and 16% respectively of the total building energy consumption. The purpose of this research is to do storage modeling using the passive energy method. The procedure is carried out with a combination of energy calculations around storage and CAD. CAD software is used to create 3D solid surface drawings and shapes. Then draw several options for the air openings that will be used. The results showed that based on the month of observation, the value of heat energy that occurred in the storage of dry harvested grain and rice with passive energy buildings was lower and heat energy was higher in June. Therefore, the solution for choosing the type of opening in January is required an opening percentage of 25% and for June, an opening with a percentage of 50% is required).

Abstract

The research is aimed at the manufacture of flaywheel for hammer mill machines using the method of drilling, milling and turning, which aims to keep the engine rotation stable on the machine due to excess load and is a mass that rotates and is used as a storage of energy inside the machine. This research focuses on drilling, milling, and turning processes on low-carbon steels. (ST 40 Steel). The Flywheel is a component that is a plate that because of its weight can withstand drastic speed changes so that the rotation movement of the machinery shaft becomes more smooth. The drilling, milling and turning methods are machining methods that are widely used in the manufacturing industry. From the results of the research using the methods of drilling, milling and turning the following are on the process of making flywheel i.e. with the time of the drilling process of the production of sepie holes 62.82 minutes, the milling process of smoothing 2 surfaces of the work object 242.06 hours and the turning of the profile of 2 surface work object 117.6 hours with a total production time of about 15 days. Therefore, the results of this research provide useful guidance for the industry to optimize the drilling, milling and turning processes in flywheel manufacturing.
