Abstract

The fish farming system in Indonesia has been widely developed because of its great potential. A common problem in fish farming systems is a decrease in water quality, therefore water replacement must be carried out continuously. Apart from that, the water is also susceptible to contamination and causes suboptimal fish growth. This problem is also experienced by fish farmers in Borong Pa'la'la Village, Pattalassang District, Gowa Regency, who produce stunted Tilapia fish, thus Tilapia cultivation activities are not very popular with residents. Community service activities (PkM) from the Department of Electrical Engineering, Faculty of Engineering, Hasanuddin University, provide solutions for revitalizing Tilapia fish cultivation by utilizing the Recirculator Aquaculture System (RAS) which is integrated with the Internet of Things (IoT) and Solar Power Plants (PLTS). The aim of this activity is to increase the production of Tilapia fish cultivation both in terms of quantity produced and in terms of the quality of the fish produced. Apart from that, it is hoped that there will be an increase in the knowledge and interest of the youth in effective and sustainable Tilapia cultivation activities as well as the integration of technology into these cultivation activities. PkM activities are carried out in the form of socialization and training for residents, as well as building a RAS-IoT-PLTS system for Tilapia cultivation. Based on the results of quantitative analysis of pre-test (before training) and post-test (after training) measurements by training participants, an increase in the level of understanding of participants reached 77 – 85%, which was quite understanding to very understanding of the RAS-IoT-PLTS system as a whole, compared to conditions before training was carried out. This indicates that this activity has achieved the expected target.

Abstract

Hydroponics is a planting technique using water-based nutrient solutions, not through soil media, like conventional farming. This hydroponic system solves the problems arising from soil-based farming that requires plowing and weeding and is susceptible to pests, climate, and the need for large land areas. However, to produce quality soil, the hydroponic system requires monitoring of nutrients, temperature, humidity, water content, pH, and light. Developing a smart hydroponic system or a system based on Artificial Intelligence of Things (IoT) can guarantee these parameters online or in real-time monitoring. The next problem is the need for a continuous and reliable supply of electrical energy so that the built AIoT-based hydroponic system can work optimally. Disruption of electrical continuity will affect the crop yields from this system. Therefore, the Community Service (PkM) activity from the Department of Electrical Engineering, Hasanuddin University, conducted socialization of the use of solar cells (solar panels) in the AIoT-based smart hydroponic system, which is a solution to the problem of the continuity of electricity supply at the Samata Green House (SGH) Group, as a partner of the activity, which still fully uses electricity from PLN. Based on the results of quantitative analysis of pre-test (before socialization) and post-test (after socialization) measurements by activity participants, an increase in the level of understanding of participants was obtained, which was initially 11-55% "quite understanding" to "understanding" of the components of the Solar Power Plant (PLTS) system, as well as how to operate and maintain PLTS, to 100% of participants "quite understanding" to "very understanding" regarding these parameters. This indicates that this activity has achieved the expected targets.

Abstract

The Wae Tuoe Fishermen Group in Pinrang Regency is a coastal community located in Suppa District, Pinrang Regency, South Sulawesi Province, where the majority of the population relies on marine resources for their livelihood. The bagang is a structure made of wood or bamboo located in the middle of the sea, about 500 meters to 2 kilometers from the shore, used by fishermen to catch or store fish. The bagang has great potential but is not optimally utilized by fishermen as a source of livelihood and economic improvement. This is because the fish catch is maximized at night. The limited lighting, which could help optimize the fishing process, is due to the restricted availability of electricity from generators. The development of solar cell technology, which can generate and store electricity, is a new breakthrough in the use of renewable energy. The use of solar cells is expected to provide an energy source for lighting on the bagang, allowing fishermen to maximize their activities at night. The solar cell lighting system is designed to supply six light points with a capacity of 5 x 50 watts operating at night from 7:00 PM to 4:00 AM. The design of the PLTS, which consists of two solar panels with a capacity of 550 Wp, four 12 V batteries with a capacity of 100 Ah, and a 1000-watt inverter, is expected to provide electricity as a lighting source for the bagang during the night. After conducting counseling and training on solar power plant (PLTS) technology, 18 out of 20 members of the Wae Tuoe Fishermen Group gained knowledge about the utilization, design, installation process, usage, and maintenance of PLTS technology.

Abstract

The Community Service Program (PkM) conducted by the Department of Electrical Engineering aims to enhance the literacy and skills of students at SMKN 10 Makassar in understanding the concept of energy monitoring and the application of Internet of Things (IoT) technology as an innovative solution for energy management systems. The main problem identified in the school is the low awareness and understanding of energy efficiency, as well as the lack of monitoring tools capable of displaying real-time energy consumption data. Through socialization and training activities based on microcontroller technology, students were introduced to the working principles of current and voltage sensors, data transmission via the internet, and digital visualization of electrical energy consumption through IoT-based platforms. The activity evaluation was carried out using pre-test and post-test methods involving 25 students from the Electrical Engineering Department to measure comprehension improvement. The results showed a significant increase in two main aspects: understanding of the basic concepts of energy monitoring, which rose from 60% to 96%, and understanding of the integration of IoT in energy monitoring systems, which increased from 20% to 88%. These findings demonstrate that implementing IoT-based learning not only broadens students’ insights into energy efficiency but also strengthens their vocational competencies in electrical engineering through the application of intelligent technologies relevant to the needs of modern industry.

Abstract

Frequency regulation and active power loss management are crucial aspects of power system operations. Battery energy storage systems (BESS) have emerged as an innovative solution to enhance grid performance, especially in addressing frequency fluctuations and reducing power losses. This study explores the role of BESS in optimizing frequency regulation and managing active power losses in the power system through several BESS integration scenarios. In this study, a BESS with a capacity of 8.437 MW was used and analyzed using symmetric steady-state simulations in DigSILENT PowerFactory software. The simulations aim to test the effectiveness of BESS in frequency regulation and minimizing active power losses in the Sulbagsel system. The analysis results show that implementing BESS can respond effectively to both over-frequency and under-frequency conditions in the Sulbagsel system. In the discharge scenario, BESS can reduce the system's average frequency by 0.02 Hz and decrease active power losses by up to 1.09 MW. Conversely, in the charge scenario, active power losses increase by 1.22 MW when the BESS is installed on Bus Tonasa. This study provides valuable insights for developing BESS-based frequency regulation strategies that contribute to the stability and efficiency of the power system.
