Abstract

Indonesia should be able to provide inexpensive solar dryers due to the availability of sunlight all year round throughout the country. This study proposes a passive direct solar dryer as it is the simplest one to construct, with aluminum mesh sheets as a heat-absorbing material, and glass fiber as an insulating material. For the cost-effective transparent cover, this study proposes 0.8 mm clear polycarbonate (PC), 2 mm clear glass, and 2 mm clear acrylic. The experimental test results of the solar dryer model showed that the highest heat efficiency value for polycarbonate (PC) is 16%, whereas the heat efficiency value for glass and acrylic is 10% and 8%, respectively. Through these findings, the construction of solar dryers is simple and low cost by using glass fiber as insulation, aluminum mesh sheets as heat absorbers, and PC instead of thin glass as transparent covers.

Abstract

The increase in greenhouse gases in the form of CO2 gas as vehicle exhaust emissions contributes to climate change. Technological approaches and alternative fuels continue to reduce fuel consumption, but this is not enough. Another method is to use eco-drive behavior, one of which is related to replacing the air filter. This study is purposed to provide guidelines for motorized vehicles operating in selected areas in Lampung Province in the behavior of eco-driving. The results of the fuel consumption test using the full-to-full method found that at each filter distance (8,000 km, 12000, and 16,000 km), vehicles operating in Mesuji with the highest deficiency, followed by Tanjung Bintang and Krui areas. In line with eco-drive behavior, for vehicles operating in Mesuji, the air filter replacement period must be faster than the other two areas, followed by Tanjung Bintang and Krui.

Abstract

Renewable energy sources originating from solar are the most environmentally friendly energy because they do not cause any pollution. The utilization of solar energy can be in the form of a direct passive solar dryer for preserving agricultural and fishery products. Solar energy has limitations related to intermittent solar irradiation, so it is necessary to add Sensible Heat Storage (SHS) material to increase thermal efficiency. Pebble stones are an SHS material that is abundantly available in a variety of colors, and suitable for solar dryers with low-temperature requirements. The study aimed to find temperature conditions and thermal efficiency through experimental tests three times, twice with SHS material, respectively white and black pebble stones, and once without SHS material. The experimental test results found that the temperature of the drying chamber was more stable with the addition of SHS material, and the highest thermal efficiency was obtained from black pebble stones, namely 49%, and white pebble stones, 40%.

Abstract

The quality failure rate in the production process in the form of defective products, scrap products, rework, rejection, and waste is an indicator of a company's quality performance, especially with regard to cost quality.  Failure in the production process will increase the rate of defects, scrap, rework, rejection, and waste, which in turn will increase the cost of quality. This study uses the FMEA method to fight identified failures from gemba walk activities. Improvements made using the FMEA method with several recommendations for improvement solutions can reduce failures, this can be seen by comparing the RPN values. The RPN failure value in the extrusion process which affected the hollow or loose PP woven sacks decreased to 98 from 490, and which resulted in lighter sack weight decreased to 98 from 490. The decrease occurred due to the achievement of the process capability value (Cpk) which was as expected ie 1.36 for denier specifications and 1.33 for yarn bandwidth specifications. This Cpk achievement has an impact on a decrease of the occurrence (o) level. Meanwhile, the failure of the RPN value in the weaving process which had an impact on products returned by customers, decreased to 98 from 490. The decrease occurred because the weaving process operator was given the responsibility to carry out maintenance and cleanliness of the machine which resulted in a decrease of the occurrence (o) level.
