Abstract

Sate is one of the Indonesian specialties whose demand is increasing, so the need for skewers is also getting higher. For this reason, innovation is needed to be able to meet these needs. Because when using skewers in a traditional/manual production method, the quality of the skewers produced is not good and the production capacity is also low. Meanwhile, the existing skewer making machine still has some drawbacks. So in this study, a bamboo cutting machine was designed to increase the production of skewers with innovations to cover the shortcomings of existing machines. In this study, the skewer making machine was designed to have a slicing section, a shavings section (making skewers), and a sharpening section. The skewers produced have a diameter between 2.5 mm to 3 mm and a length of 210 mm with a production capacity of 3000 skewers per hour.

Abstract

A dehumidifier is a device for drying air by releasing moisture. A dehumidifier with a thermoelectric cooler has the advantage of being more compact and has the potential to be combined with an air heater. This study aimed to determine the effect of thermoelectric power and airflow on air temperature and relative humidity. The research method uses direct experiments with six pieces of thermoelectric as a coolant. The data taken are the cooler surface temperature, the air temperature that is dried, and the humidity of the air. The test results show that the dried air temperature can reach 25.6oC with 78% humidity in environmental conditions with an ambient air temperature of 31oC.

Abstract

Indonesia is one of the tropical countries where there are many entrepreneurs engaged in chili farming found in rural areas. Chili is a commodity plant that is in great demand throughout the world and in Indonesia, therefore without good processing or preservation, the quality of chili quickly rots and the price drops in the market. In the chili processing process, it is very dependent on sunlight, but due to the uncertain climate and drying using sunlight, it needs a long and unhygienic process, causing the chili processing process to be hampered. For this reason, the design of a drying system that utilizes heat from burning charcoal is specifically designed to speed up the drying process. This chili drying system utilizes heat from burning charcoal in the furnace and flows hot air into the system with the help of a blower whose speed is varied, namely 6000 Rpm, 4000 Rpm and 2000 Rpm, with variations in the testing capacity scale to determine the tamping power on an efficient rack when this dryer works. After testing the tool, it is known that in a drying time of 30 minutes, the variation is more effective with an even distribution of heat in the system with a maximum blower speed of 100 grams with a drying rate of 20% to 30%.
