Abstract

Solar Power Plants are one of the renewable energy sources that are widely developed because they are environmentally friendly and sustainable. However, the performance of photovoltaic systems is highly influenced by environmental conditions, component degradation, and the effectiveness of system management and maintenance. Therefore, a reliable and real-time monitoring system is essential to maintain the efficiency and reliability of solar power plants. The development of Internet of Things (IoT) technology provides an effective solution thru the integration of sensors, microcontrollers, communication networks, and cloud-based platforms, enabling real-time remote monitoring. This article presents a literature review on an IoT-based solar power plant monitoring system by analyzing various studies published between 2018 and 2024. The discussion focuses on the monitored parameters, system architecture, devices used, and communication methods and monitoring platforms. The study results indicate that the most commonly monitored parameters include voltage, current, power, module temperature, and environmental parameters such as solar radiation intensity and humidity. Additionally, the layered architecture of IoT systems has proven capable of enhancing flexibility, data accessibility, and decision-making effectiveness. Nevertheless, challenges such as dependence on internet network quality, sensor accuracy, and data security remain major concerns in the future development of IoT-based solar power monitoring systems.

Abstract

The increasing need for environmentally friendly energy sources encourages the development of renewable power systems, including Solar Power Plants (PLTS). Indonesia, with its abundant solar radiation, has great potential for implementing solar-based energy systems. This study focuses on the design and construction of a 500-watt off-grid PLTS system integrated with an Internet of Things (IoT)-based monitoring system to provide an alternative, eco-friendly power source. The novelty of this study lies in the implementation of real-time monitoring through a NodeMCU microcontroller connected to the Blynk application, enabling remote observation of system performance parameters such as voltage, current, and power output.The research employed an experimental approach consisting of system design, component assembly, and performance testing. The main components include polycrystalline solar panels, a silicon-controlled rectifier (SCR) as the solar charge controller, a 12V/35Ah battery, and a 500-watt inverter. The IoT-based monitoring system used the PZEM-004T sensor and DC voltage sensor connected to the NodeMCU ESP8266 microcontroller. The testing results show that the 500-watt PLTS system can stably supply a total load of 313 watts for 2.35 hours under optimal sunlight conditions. The inverter output voltage averaged 230 VAC, while IoT monitoring data corresponded with manual measurements, indicating reliable system accuracy. The PLTS system successfully demonstrated stable performance, easy maintenance, and remote monitoring capability, making it suitable as an alternative energy solution for areas not covered by the PLN grid.

Abstract

Abstract-- Dry organic waste has the potential to be utilized as maggot feed; however, it requires a specific particle size to ensure optimal consumption and nutrient absorption. The recommended feed size for maggots is approximately ±1 cm, making a shredding process necessary. This study aims to design, manufacture, and test a gravity-based dry organic waste shredding machine for maggot feed. The design innovation is achieved by positioning the electric motor and shaft vertically, allowing the material to utilize gravitational force for continuous shredding. The machine is designed using a 0.5 HP electric motor with a pulley and V-belt transmission system. Testing was conducted with waste mass variations of 500 g, 1000 g, and 1500 g. The observed parameters included shredded particle size, shredding time, yield, and actual shredding capacity. The results show that the machine is capable of producing an average particle size of 1 cm, with an average yield of 89.59% and an average shredding capacity of 171.84 g/min. These results indicate that the designed shredder is effective as a supporting tool for providing maggot feed from dry organic waste. Keywords: shredder machine, organic waste, maggot feed, gravity system

Abstract

This study aims to optimize the drilling process of 18 mm diameter holes in excavator cover brackets through a tool redesign. Previously, the hole drilling process required 58 minutes of cycle time, using two different tools for drilling and chamfering the hole entrance. This lengthy processing time can be reduced by redesigning the tool. In this study, the drilling and chamfering tools were integrated into a single tool. This integration eliminates repetitive tool changes during the machining process.The research employed an experimental approach by modifying the tool design and testing the drilling parameters on a CNC machine to ensure that product quality was maintained. The evaluation was conducted by analyzing process capability data (Cp and Cpk) using Minitab version 22 software. The results show that the redesigned tool successfully reduced the cycle time to 22 minutes, representing a 62% reduction, without compromising production quality. The Cpk values for hole diameter, depth, and chamfer remained above 1.33, indicating that the process after tool replacement remained highly capable and stable. It can be concluded that redesigning the tool is an effective solution for improving production efficiency without reducing product quality.
