Abstract

Many cases of death of chicks in farmers are caused by drastic changes in temperature which result in stress and death of chickens. In this study the authors made a chick coop design equipped with an LM35 sensor which functions to control the temperature of the chicks. The research object is Bangkok chicken aged 7-10 days which has a temperature requirement of 300oC. The test results show that the temperature stabilizer incubator for both the sensor test separately and the integration of the incubator control system as a whole works according to the program design, this is based on the test results that the lights and fans work according to the LM35 sensor reading input with 100% accuracy where as long as 3 days of testing the average temperature of the first, second and third days is below 300oC so that the output is in the form of lights on and the fan is off. On Day 3 all the chickens were healthy and growing well.

Abstract

This research investigates short-circuit problems in induction motor stators by constructing a motor with a changing winding and leaking flux data. The data is used to evaluate X, Y, and Z axes and map motor waves under normal and abnormal conditions. This study is expected to compare the effectiveness of the observation method from three different axes at the same motor condition to be further helpful in repairing induction motor damage caused by the circuit. From the results of the study, it shows that the harmonic value of the stator current will be more effective than the Y axis with a harmonic amplitude value of -38.8 dB, higher than the harmonic value of the current on the X axis with a difference of 33.89 dB and a difference of 0.32 dB from the Z axis. Suppose the disturbance is measured from the stray harmonic value. In that case, the flux will be more effective than the X axis with a harmonic amplitude value - 25.27 dB, higher than the harmonic value of the flux on the Y axis with a difference of 6.425 and a difference of 4.85 dB from the Z axis.

Abstract

Water quality and temperature are important parameters that need to be considered in fish farming. Inappropriate water quality and temperature parameters can inhibit fish growth, and can even cause fish death so that farmers experience economic losses for the pond. The focus of the problem in this research is that inappropriate water quality and temperature parameters can inhibit the growth of catfish or cause death, thereby economically harming the cultivation business. The process of monitoring water quality in catfish ponds which is carried out manually is considered less efficient because it does not provide real-time temperature control. This research aims to design and implement an Internet of Things (IoT)-based water quality monitoring system in catfish cultivation ponds, with a focus on real-time temperature regulation. This research is experimental research with the subject of catfish cultivation ponds. Data was collected through IoT-based system testing, and the results were analyzed using descriptive methods to evaluate the system's effectiveness in maintaining pool temperature in the range of 28°C–32°C. The research results show that the IoT-based catfish farm monitoring system with the ESP32 microcontroller and DS18B20 sensor functions well in monitoring water temperature in real-time. This system is capable of sending data wirelessly to a web or application-based monitoring platform, allowing users to monitor farm conditions anytime and anywhere. The implications of research on IoT-based catfish farm monitoring using an ESP32 microcontroller and DS18B20 sensors show the potential for transformation in aquaculture management , especially catfish farming.

Abstract

Arch flash is a disorder that often occurs in the electrical system of an industry or factory. In this research focusing on the analysis of the protection system by considering arc flash, it will be discussed in detail at the existing factory in East Java, namely PLTU Paiton unit 3 which is developing a unit with a capacity of 1x815 MW. The electrical system at PLTU Paiton unit 3 discusses only high and medium voltage systems. In order to support the continuity of the plant, to connect the Java-Bali electricity system, it is necessary to have a good protection coordination system to avoid black out due to one of the impacts caused by the arc of fire. After coordination of protection in the Paiton PLTU unit 3 system, arc analysis will be simulated with IEEE 1584-2002 standard calculations to find the  magnitude of energy incidents and determine the safety limits of workers and also personal protective equipment according to NFPA 70E standards. The results of the study after resetting the protection coordination of PLTU Paiton unit 3 using differential rele on the SWGR-3A bus incident value of arc energy and Flash Protection Boundary (FPB) value decreased which originally reached a level outside level 4 (>40cal / cm2) to level 3 (8.1-25cal / cm2), on the SWGR-3B bus the incidence energy value was at level 3 (8.1-25cal / / cm2) dropped to level 2 (4.1-8cal / cm2), for coal hand sys bus SWGR A the energy incident value from level 3 (8.1-25cal//cm2) drops to level 0 (0 -1.2cal/cm2), while for the coal hand sys SWGR B bus the energy incident value when existing conditions reach level 3 (8.1-25cal//cm2) drops to level 0 (0-1.2cal/cm2). After obtaining the energy level of the bus, then personal protective equipment can be determined.
