General Background Catfish cultivation is a major freshwater aquaculture activity widely practiced in Indonesia, particularly in urban areas with limited land availability. Specific Background The bucket-based aquaculture system (budidamber) provides a compact solution, yet requires frequent water quality monitoring and maintenance. Knowledge Gap Manual water control often leads to delayed maintenance due to farmers’ time constraints, reducing water quality and affecting fish survival. Aims This study aims to design and implement a semi-automatic IoT-based system for monitoring and controlling water quality in bucket catfish cultivation. Results The system utilizes ESP32, temperature sensor DS18B20, ultrasonic sensor, and Telegram-based control, achieving an average water temperature of 28.9°C within the acceptable standard range and enabling automated water drainage with an average delay of 11 seconds and deviation of 4%. Novelty The integration of real-time monitoring, automated drainage scheduling, and remote control via Telegram provides a practical semi-automatic solution for small-scale aquaculture. Implications This system supports efficient time management for farmers and improves water quality control, contributing to sustainable small-scale aquaculture practices in limited-space environments. Keywords: Internet of Things, Budidamber, Water Quality Monitoring, ESP32, Aquaculture System Key Findings Highlights Remote monitoring system maintains stable water conditions within standard limits Automated drainage operates with minor delay under real conditions Integrated messaging control simplifies operational management for farmers

Abstract

General Background The increasing demand for electrical energy requires alternative solutions to support power generation, especially in remote areas. Specific Background Permanent magnet generators provide a practical approach by converting mechanical energy into electrical energy without requiring external excitation. Knowledge Gap However, the influence of varying magnet quantities in modified generators from used equipment has not been clearly explored. Aims This study aims to design and test a generator from a used water pump with variations of 8, 10, and 12 neodymium magnets on the rotor. Results Experimental results show that the generator with 12 magnets produces the highest output, reaching 51.7 V at 1500 rpm, 68.0 V at 2000 rpm, and 82.9 V at 2500 rpm, while lower magnet variations produce significantly smaller voltages and currents. Novelty The study introduces a modification approach using a used water pump combined with varying magnet configurations to optimize electrical output. Implications The findings indicate that increasing the number of magnets significantly improves generator performance, offering a simple and low-cost solution for small-scale electricity generation in areas with limited access to conventional power sources. Keywords: Permanent Magnet Generator, Electrical Energy, Neodymium Magnet, Rotor Modification, Voltage Output Key Findings Highlights Highest output achieved at maximum rotation speed with largest magnet configuration Smaller configurations generate minimal electrical output under load Output characteristics differ significantly between load and no-load conditions

Abstract

A generator is a device or engine that generates electrical energy from the presence of mechanical energy obtained from a prime mover in the form of a diesel engine as the prime mover which then drives an AC generator or alternator, causing an electrical voltage. The aim of this research is that the generator can supply electricity needs at the Sumur Welut site by changing or modifying diameter of the wire on the alternator. This analysis includes the Stator and Rotor on the Alternator generator so that it can produce the electricity needed. From the test results, the load generated after being modified can supply power at the site but the fuel consumption is more wasteful, namely 0.9 liters / minute and also the generator temperature increases to 88.2 C. So that the radiator planning is done by changing the surface area of ​​the radiator from 2915 cm2 to 8077 cm2. Or change the radiator fan, which originally changed the wind speed of 4.7 m / s to 13 m / s. Keywords: Generator, Alternator, Load Testing, Radiator, Cost.

Abstract

Indonesia is a tropical country, which gets a lot of sunshine every year. Harvesting energy from solar heat is an alternative solution to obtain renewable and environmentally friendly electrical energy. The purpose of this research is to design and test the temperature and flow of the working fluid of a solar collector for energy harvesting. The method used is true experiment research by making a solar collector prototype. Measurement of the temperature and pressure of the working fluid is carried out by varying the power of the heating lamp as a substitute for sunlight in the test. The experimental results show that the greater the heat energy received by the solar collector, the higher the temperature of the working fluid and the resulting pressure during the same test. The highest temperature recorded for the liquid coming out of the solar collector reaches 63.6 oC with a maximum pressure difference of 19.6 Pascals. The results of this test will be followed by testing the flow rate of the working fluid to determine the power potential of the working fluid for harvesting energy. Highlights: Efficiency Enhancement: Optimizing solar collector design for increased heat energy absorption and efficient energy conversion. Temperature-Pressure Correlation: Investigating the relationship between heat energy, working fluid temperature, and pressure for better energy yield. Flow Rate Analysis: Assessing working fluid flow to gauge energy potential and inform effective energy harvesting strategies. Keywords: solar collector, temperature, fluid pressure, energy harvesting
