Abstract

A coffee roasting machine is a machine that is used to roast coffee beans to ripen. The working principle of this machine is that the coffee beans are heated in a rotating roaster with a predetermined temperaturee, so that the heating can be evenly distributed. The process of roasting coffee beans can be adjusted to temperaturee, in which the heating element of the tool uses a Band Heater component. Band Heater is shaped like a tube with a function as a heater to heat a cylinder of a certain size which has advantages such as high operating temperature, fast heating, high heat efficiency, environmentally friendly, even and accurate heating, can adjust the automatic control system. The purpose of this study was to design a controlled coffee roasting machine using an electric heating system of the band Heater type with a capacity of 5 kg and to know the PID Rex-C100 temperaturee control on a coffee roasting machine with a capacity of 5 kg. This study show  temperature rise every 10 minutes during the roasting process, a graph of the difference in temperaturee every 10 minutes during the roasting process, data on the measurement of the heating system temperaturee, a graph of the relationship between the heater band temperaturee and heat flow, the comparison of the temperaturee bands. heater with roasting chamber, and graph of the required power band heater.

Abstract

Increasing heat transfer in condensation for low surface tension fluid is dominated by using extended area (fin). One of the extended area on pipe is integral fin tube. Designing of integral fin tube should be conducted due to generate optimal condition such as designing fin spacing. Fin spacing has significantly impacted to heat transfer enhancement. Whereas the material of pipe is copper since has higher heat conductivity than others and fluid working is methanol. To predict optimal geometry of integral fin tube is conducted by using mathematical simulation by dividing area into flooded and unflooded. The active area or unflooded area represents the heat transfer area adn enhancement. In this experiment is found that the optimum fin spasing is 1 mm

Abstract

Some problems that often occur with electric motorbike batteries include overcharge, overdischarge and overheat. To avoid these problems, it is necessary to regulate or monitor the battery, which is called a Battery Management System (BMS). The BMS in this research is focused on the use of PSDKU Kediri electric motors. With this BMS design, it is hoped that it can be used as a reference in battery system management so that the battery lasts longer. In this study, 112 batteries were used, consisting of 14 series and 8 parallel. The voltage sensor circuit is made to determine the battery cell voltage so that overvoltage and undervoltage protection can be carried out. Measurements can be made using a multimeter by adjusting the reading position on the voltage. The maximum voltage produced is around 57.7 volts with a charging time of 7 hours
