APPLICATION OF FISH FLOUR GRINDING MACHINE IN THE SAMATURU FARMER GROUP IN SEGERI DISTRICT, PANGKEP REGENCY

Bawasalo Village, Sigeri Subdistrict, South Sulawesi Province is geographically located on the coast with themain livelihoods of its people as freshwater fish aquaculture fishermen or catching and selling fish. The mainproblem faced by fishermen and fish entrepreneurs, because fish are a commodity that is rapidly decliningquality or rot that can only last a maximum of 5 hours and even faster at room temperature. The lack ofknowledge about the use of fish waste and the absence of application of technology in fish wastemanagement. This is why fish waste is only disposed of at sea or sold to collectors at a low price. Even thoughfish waste can be processed into fish flour which is very good as additional nutrition for livestock and fishfeed. Based on the analysis of the situation, some of the problems faced by the business group can bedescribed, namely: Utilization of fish is still limited as a product to be marketed directly (fresh fish), there isno knowledge of how to use leftover fish so that it is only disposed of and becomes a disturbing waste, there isno adequate tools for processing fish waste into useful processed products, especially for fish meal and fishfeed, the need for business development to increase their income besides fishing for fish. Especially when seaconditions are not possible, fishermen cannot go to sea and do not earn income, do not understand businessmanagement and bookkeeping. Besides, fishermen and fish entrepreneurs are still dependent on factory-madefeed, so farmers / fishermen must provide sufficient funds to animal feed costs. As we know that the price offactory production feed is increasingly expensive. The purpose of this PKM activity is the application of a fishwaste grinding machine into fish meal at UKM Partners. The method of solving the problem offered is tointroduce and demonstrate the fish meal grinding machine that drives an electric motor with the followingsteps. Conduct cooperation with related institutions of the Regional Government of Pangkep Regencyespecially the Industry and Trade Office of Pangkep Regency and the Head of Bawasalo Village, SigeriDistrict in the framework of family development fish farmers / fishermen. Conduct extension activities byintroducing appropriate technology to fish meal grinding machines that are driven by electric motors. Holddemonstrations / demonstrations and train partners to make and assemble high-quality, high-quality fish mealgrinding machines

Power Flow Analysis in N-1 Contingency Conditions Due to the Entry of Renewable Power Plants in the Sulselrabar System

Contingency analysis on a 150 kV network aims to see the network's reliability against interference. Contingency is a scheme for releasing one element of the generating unit or transmission line (N-1), which will affect the performance and reliability of the electric power system. Power flow analysis in an electric power system is an analysis that reveals the performance of an electric power system and the flow for certain conditions when the system is working. The analysis was carried out using the ETAP 16.00 software. The method used was the newton raphson to calculate the load flow in the N-1 contingency condition. From the results of the study, it can be seen that the power flow occurs in each channel of the 150 kV system in the South Sulawesi system. When conducting a contingency analysis of N-1 by removing the load on the middle lane of South Sulawesi, namely Maros and Sidrap, a voltage change occurs, increasing buses experiencing critical and marginal voltage conditions. This happens because of the sudden release of essential loads, so over or under voltage appears on the bus

Optimal Design of PSS on SMIB Using Particle Swarm Optimization

Dynamic disturbances in the power system are caused by sudden changes in load. This condition causes the stability of the generator to be disturbed, such as the emergence of oscillations in the generator in the form of oscillations of frequency and rotor angle. Power System Stabilizer (PSS) is an additional control that can increase generator stability. To get optimal PSS performance, proper tuning of PSS parameters is needed. Optimal performance of PSS can cause the frequency response and angle of the SMIB rotor to be stable. In this study, PSO is used for optimization of PSS parameters. PSS is able to provide stability so that overshoot oscillations can be suppressed, as well as faster settling time performance for the system to reach steady state conditions. To test the reliability of the SMIB, a case study of adding and subtracting loads was used

Dynamic performance comparison of DFIG and FCWECS during grid faults

Among several types, variable speed-based wind turbine generator (WTG) is the most popular type installed worldwide. This type of WTG is able to extract 5% more energy from wind speed compared to the fixed speed WTG. There are two kinds of variable speed based WTG; Doubly Fed Induction Generator (DFIG) and Full Converter Wind Energy Conversion System (FCWECS). DFIG and FCWECS are placed at the first and second topWTG installation worldwide since 2004. However, both of them are very sensitive to the grid dip fault and may violate the allowable margins identified by various international Fault Ride Through (FRT) codes. This paper aims to investigate the responses of DFIG and FCWECS during certain level of grid dips and compare their performanceunder such event. Results show some differences of the performance of DFIG and FCWECS during voltage sag event, however the voltage profile at the point of common coupling is much better in case of DFIG. Results also recommend that DFIG can be effective when connected to weak grids whilst FCWECS is preferably to be connected to strong grids

Modeling and implementing a load management system for a solar home system based on Fuzzy Logic

Solar Home System is one of the technologies for utilizing solar power at home. To optimize the performance of PLTS, it is necessary to regulate the use of electrical energy. In this research, an effort is made to control the load using fuzzy logic to regulate the power consumption used by the load so that energy can be utilized effectively. The fuzzy logic method works based on the input given so that the desired results can be as expected. To test the effectiveness of the fuzzy logic method, this study was tested with two types of loads: lighting and fan loads. For lighting loads, it uses two light sensor inputs, and for air conditioning, it uses two temperature sensor inputs and a PIR sensor. The test results show that in the experiment of setting the light load using fuzzy logic, the average power usage at the load is 11.31 watts. In contrast, without fuzzy logic, the average power usage value for the load is 14.29 watts. In the fan load control experiment using fuzzy logic, the energy consumption setting was obtained according to the room temperature input and the number of people in the room. The test results received power usage without using fuzzy logic, where the average fan power usage value is 4.32 Watts, while without fuzzy logic, the average power usage value is 2.97 Watts. For one sensor input, the average power usage value of the average fan is 3.02 Watts; without fuzzy logic, the average power usage value is 2.93 Watts for two sensor inputs.

Monitoring the Condition of the 20 kV Switching Substation in the Tual Rayon Saumlaki Area

A 20 kV cubicle is a set of electrical equipment installed in a distribution substation as a distributor, circuit breaker, connector, controller, and protection system for the 20 kV voltage power distribution. The frequent issue in these cubicles is corona discharge on electrical equipment, which is a phenomenon occurring when the air around conductors or conductive materials becomes ionized, resulting in the release of charges that can lead to insulation failure in the equipment. The consequences are severe as it can damage the equipment inside the cubicle and cause power losses. This research analyzes the influence of humidity, temperature, sound, and light conditions inside the cubicle to identify the symptoms of corona discharge in the 20 kV cubicle and its accessories. The goal is to create a tool that can address and anticipate the issues related to corona discharge caused by the effects of humidity, temperature, sound, and light
