Abstract

Sapanang Village is a village located in Binamu District, Jeneponto Regency, South Sulawesi Province. One of the livelihoods of the people in Sapanang Village is derived from agricultural products, agricultural commodities that are often cultivated, one of which is corn. However, behind the large number of cultivated corn plants, it produces waste called corn cobs. Corn cobs are sometimes simply thrown away by the community, therefore the solution offered regarding the corn cob waste problem is to make corn cob briquettes which are an environmentally friendly solid alternative fuel. The service method used in this work program is to prepare the necessary tools and materials and then socialize how to make corncob briquettes to the public. From the socialization that has been carried out, it can be the answer to the problem regarding corn cob waste that is simply wasted which is used to become something useful, such as being processed into corn cob briquettes as an environmentally friendly, cost-effective and long-lasting fuel. The work program activities that have been implemented have been carried out well and received a positive response.

Abstract

The heating process is a technique for preserving and processing foodstuffs. One of the methods that can be used is ohmic heating method. Ohmic reactors system today on the less optimal of the ohmic reactor performance so that additional control system is required for the ohmic reactor. The purpose of this research is to produce a fuzzy expert control system in the ohmic reactor to optimalize the performance of the ohmic reactor. This research conducted by creating hardware and software. The test used a salt solution at a concentration of 1%, 2%, 3%, 4% as the test material. Heating is carried out at each solution concentration. The analysis result of the temperature response showed that the fuzzy expert control system in the ohmic reactor is operating well. This can be seen from the overshoot of the solution temperature only at a concentration of 4% of 2 ℃ for 4 seconds while in fuzzy showed an overshoot of 3 ℃ for 2 seconds. In addition, the setting time to reach the setting point was relatively small and the solution temperature was relatively stable. The fuzzy expert and fuzzy control systems have low steady state errors ranging from 1,1% and 2,2%. Meanwhile, the analysis results of the temperature response in the on-off control system do not meet the criteria for the success performance control due to overshoot, unstable solution temperature and large steady state errors in each solution concentrations. The used energy analysis found that the electrical energy used by fuzzy expert control system was 49169,2 Watt.s and fuzzy Sugeno was 45121,5 Watt.s.
