Abstract

The high price of chicken feed makes it difficult for farmers to develop their livestock business. This is also experienced by Mr. Pardamiyan Siregar, who has 50 chickens of various ages. Chicken is a type of livestock that relatively eats any kind of food, including grains, green vegetables, and household leftovers. It is easy to feed chickens, including the food scraps mentioned above, but it is not always available, and the amount is minimal. Therefore, this service partner must provide feed through ground corn and fine rice bran purchased at animal food stores. The cost that partners must incur is IDR 47,000 per day or IDR 1,410,000 per month. The partner wishes to reduce the feed cost by grinding the round corn purchased from the store. The desire is based on the price difference between round and ground corn. The price of round corn is only IDR 6,000/kg, while ground corn is IDR 8,000/kg so that the partner can save IDR 2,000/kg in feed costs. If the amount of ground corn given to livestock is 3 kg, then partners can save IDR 8,000 daily. The high cost of feed procurement and the promising profit prospects encourage partners to collaborate with the implementation team to find solutions to the problems faced by partners. According to the implementation team, the most appropriate solution to overcome partner problems is the provision of assistance with corn grinding machines. To achieve maximum success in helping partners, the program implementers arranged the following implementation steps: location surveys and interviews to explore the main problems, analyze the situation and conditions of the partner's business, determine solutions, prepare the implementation of machine manufacturing programs, machine grants, training, and program evaluation. The result of this service program is one unit of corn grinding machine with a capacity of 50 kg/hour. The machine uses a 1.5 hp electric motor drive with a grinder rotation of 180 rpm. The size of the corn grains produced ranges from 1 mm to 2 mm. This grain size allows it to be eaten by chickens (poultry) of all ages.

Abstract

Mechatronics, as an interdisciplinary field integrating mechanical, electrical, computer, and control engineering, provides innovative solutions for energy and environmental challenges in urban regions. This study conducts a systematic literature review and meta-analysis using open access datasets to evaluate solar energy potential, electricity reliability, and air quality in Medan, North Sumatra. Results show that the city has strong solar irradiance levels, averaging 5.75 kWh/m²/day, indicating substantial feasibility for photovoltaic deployment. Electricity reliability, assessed through SAIFI and SAIDI indicators, is more stable in Medan compared with other Indonesian cities, offering a favorable foundation for renewable integration. Air quality analysis reveals moderate conditions, with PM2.5 concentrations averaging 28 µg/m³, slightly above World Health Organization standards, yet lower than Jakarta and Pekanbaru. Across all dimensions, mechatronics applications, including smart grid automation, intelligent inverters, IoT-based environmental sensors, and robotics-assisted monitoring emerge as crucial tools to bridge research and implementation gaps. The study identifies limited adoption of techno-economic feasibility analysis, localized reliability assessments, and distributed sensor networks in Medan, which restricts practical deployment. Future research should emphasize mechatronic frameworks such as predictive control, cyber-physical systems, and stochastic modeling to improve resilience. Policy recommendations highlight the need for targeted incentives, pilot projects, and interdisciplinary collaboration. Overall, this work positions mechatronics as a key enabler for sustainable energy transition and environmental management in Medan, offering insights applicable to other rapidly urbanizing regions in Indonesia.
