Abstract

One agricultural commodity that has high economic value is the clove "Eugenia Aromatica". The many benefits obtained from cloves, making clove commodities sell well in the market due to of high demand. Therefore, the amount of clove production must be able to balance the market demand in order to keep price stability stable. However, post-harvest handling of cloves at the farm level is generally conventional. This has caused problems including long working time (ineffective), the risk of clove quality decreases, and causes discomfort to the skin of workers' hands due to friction of the clove flower for long time. Hence, it is necessary to conduct IbM – “Ipteks bagi Masyarakat” (Science and Technology for Communities) activities in utilizing clove flower separator machines for farmers in Bonto Village, Enrekang. The stages of the implementation of the IbM activities were observation to the farmer groups in Bonto Village, procurement of clove flower separators, conducting training to operate the clove separator mechine and counseling how to do mechine maintenance to farmers in Bonto Village. The results obtained from this community service activity are that clove farmers in Bonto village are able to work more effectively and efficiently in the process of separating clove flowers from their stems so that the production of cloves increases with good quality.

Abstract

The cement industry is one of the energy intensive industries, because it absorbs a large amount of energy, and the kiln is the heart of the thermal energy system which is used as a place for combustion and clinker formation, therefore efforts are needed to determine the effect of using rice husk fuel on additional energy needed for combustion in the kiln and knowing the magnitude of the effect of adding rice husks on coal savings. This research was conducted to collect operational data of kiln which was obtained from the Central Control Room (CCR) Unit of Tonasa IV Factory of PT. Semen Tonasa. Data is taken directly on a computer which functions to regulate the operation of all production processes at the Tonasa IV Factory. The results of the analysis show that the use of rice husks has a relatively small effect on the energy produced when compared to without using rice husks. The addition of rice husk fuel does not show a significant effect on coal savings, but using rice husks can provide a calorific value of 3300 kcal / kg. In 1 kg of rice husk contains a calorific value of 3210 kcal / kg while in 1 kg of coal contains a heating value of 4910 kcal / kg, it can be seen that 1 kg of rice husk can replace approximately 1.53 kg of coal.

Abstract

This study aims to make a prototype mechanism for opening and closing the gate on a hydropower dam using the Arduino Uno microcontroller. The research was conducted by making two gates (gate-1 and gate-2) which will open or close based on the water level of the dam. Gate-1 and gate-2 will close if the water level of the dam does not exceed the limit for immediate reduction. The test was carried out with variations in the conditions of water entering the dam, namely calm water conditions, heavy water conditions, and low water conditions. From the tests carried out, it was found that gate-1 always opens when the water level reaches 8 cm or more, while gate-2 opens when the water level starts to reach 11 cm. The length of time gate-1 and gate-2 open according to the water level of the dam.

Abstract

The limitation in energy provision has become quite a crucial issue. The oil reserves in Indonesia continue to decline, and a similar situation is occurring with coal reserves. Thus, a conventional and renewable energy source is needed that does not harm the environment, for example, solar energy. This research aims to harness solar energy that can still be converted into electrical energy, and it also aims to improve the power output of solar panels for better optimization. The research starts by planning the motor, battery capacity, and solar panel capacity. Field testing is conducted at Merdeka Field, Ujung Pandang State Polytechnic, and data is collected under two conditions: with the use of a sun tracker and without a sun tracker. The power output obtained from each solar panel is then calculated. Based on the research results, the testing using a sun tracker yielded a power output of 17,857 Watts with a horizontal position of 47° Northeast and a vertical position of 15° at 11:30 AM WITA (Central Indonesia Time). Meanwhile, during the testing without a sun tracker, it resulted in a power output of 16.2 Watts with a horizontal position of 0° North and a vertical position of 5° at 1:00 PM WITA, indicating an average increase of 43.03%.
