Abstract

Relay is a tool that helps the protection system on the electric power network to check electrical equipment from disturbances that can damage the equipment, such as short circuit faults. Relays are divided into several types, one of which is the Over Current Relay (OCR). The OCR has the function of an electric power equipment function from short-circuit faults of phases. OCR has several different characteristics, such as the IEC inverse standard and the ANSI inverse standard. Each OCR characteristic has a difference in the basic formula and the resulting output curve. In IEC standard characteristics, the output of the relay is in the form of an L curve, that is, the greater the setting time, the greater the setting current in the relay. The substation has several transformers, each of which has two OCR relays, namely an OCR relay on the high voltage section (150kV) and an OCR relay on the middle low section (20kV). ETAP software is an application that can determine the coordination and output value of the work relay, making it easier to simulate relay work. However, if the relay simulation does not work according to the provisions, the settings on the relay can be changed to get the appropriate value. The Particle Swarm Optimization (PSO) method is one method that can improve the setting value on the relay so that it can work according to the provisions set by PT. PLN (Persero). In this study, the relay working simulation uses ETAP software and uses the PSO resetting relay method. The result of the travel time between the 150kV and 20kV sides of transformer 5 before using the PSO method is 3.05s on the 150kV side and 2.72s on the 20kV side, while before using the PSO method it is 3.4 on the 150kV side and 3.02s on the 20kV side. The time intervals before using and before using PSO were 0.33s and 0.38s. Based on the Manual of Conductor Protection and Control Maintenance, the delay between relays is 300-800 milliseconds. Therefore, the delay interval on the transformer relay 5 has worked well with using the PSO method or not according to the existing protection guidelines. Keywords — Relay, Over Current Relay, time setting, current setting, delay time, ETAP , particle swarm optimization.

Abstract

Internet of Thing (IoT) is a concept where an object has the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. IoT really helps technological developments, especially in terms of monitoring. In this study, an IoT based automatic monitoring system for catfish that designed focus on the quality of its water. The variables that are controlled in this system are temperature and turbidity of water in the fish tank. Temperature control occurs when the temperature sensor detects a temperature lower than ideal temperature, then the system will turn on the heater until the temperature back to ideal. Water turbidity control occurs when the turbidity sensor detects that the water turbidity exceeds the normal limit, then the system will open the solenoid valve so that water will be discharged. The values of water temperature and turbidity will be displayed realtime on the LCD and Blynk.Keywords— catfish cultivation, internet of things, automatic, temperature, turbidity, monitoring

Abstract

Recording is all kinds of recording activities such as identification activities, genealogy records, production and reproduction records, as well as health records. This activity is the basis for the fattening process on cattle farms. One of the important measurement criteria in animals is weight. Weight measurements must be accurate and also require an adequate monitoring system so that the recording results are easy to monitor. Accurate and easy-to-monitor recording results will make maintenance management optimal so as to make optimal growth of cattle as well. However, the current traditional breeder recording equipment used monitoring system is still not optimal. Therefore, the purpose of this research is to design a Monitoring System for Cattle Body Weight Recording Devices Based on the Internet of Things. The system is equipped with realtime data transmission which is stored in a database and displayed on the website. The database is created using services from firebase. With IoT monitoring, cattle weight measurement values, RFID tag data, measurement time, and age can be accessed via a website that aims to make it easier for users to view realtime data and recapitulate measurement data. The results of the research conducted, the system runs according to design. In the test of sending heavy data, RFID tag data, time and date into firebase the success rate is 100% and website functionality also has 100% success. The data obtained from testing the delay in sending data to firebase obtained an average delay of 0.97 seconds. the highest delay value is 1.36 seconds and the lowest value is 0.72 seconds. The throughput on the system is 1990 bits/sec. Keywords : Recording, Weight, Monitoring, Internet of Things, firebase

Abstract

In 2021, the trend for beef production in indonesia is likely to decline, not in line with the increase in the cattle population. According to the Directorate General of Livestock and Animal Health, Indonesia's beef production was 437,783.23 tons, a decrease of 3.44 percent compared to 2020 of 453,418 tons (Qodriyatun, 2022). The reduced supply of beef in Indonesia is due to the weak synchronization between reproduction management and butchering. The reason is that 78% of national beef production comes from smallholder farms (Zakiah, et al, 2017). In the recording studio, the people are still getting less attention. Recording is all types of recording activities such as assistance activities, genealogical records, production and reproduction records, maintenance management records and livestock health records in certain populations. The Internet of Things (IoT) can be applied to various aspects, especially as a system for recording, storing, sorting and processing data. This application can be used in the system for recording body weight of cattle. For this reason, a system for recording body weight based on the internet of things was designed. The internet of things based body weight recording system uses 2 Load Cell sensors to weigh the body weight of the cow and an RFID sensor to read the identity of the cow, besides that the sensor system has a website as a user interface. It is hoped that this application can increase the efficiency of the process of recording body weight of cattle and produce an intelligent tool system. Keywords: IoT, Recording, Load Cell, RFID

Abstract

During the Covid-19 pandemic, caring for ornamental plants was one of the activities that many people liked, resulting in a drastic increase in demand for ornamental plants. However, the process of caring for plants that can bring out their uniqueness is very difficult. The puring plant (Codiaeum Variegatum) is an ornamental plant that is unique in its leaves, the puring plant grows in tropical climates, and requires sufficient water. The benefit of croton plants is that they can degrade the pollutants around them. To optimize the care of croton plants, a device is needed that can meet the water needs of croton plants. The research begins with designing device designs and control systems. Followed by assembling the prototype device and testing it according to the characteristics of the croton plant. Furthermore, data collection and analysis were carried out using the Mamdani method of fuzzy logic control. The fuzzy logic control will regulate the soil moisture needed by croton plants, with a setpoint of 30%RH which is the ideal humidity for croton plants. The test results show that the device can function according to the design that has been made.Keywords: Croton Plant, Fuzzy Logic Control, Mamdani Method, Soil moisture

Abstract

A dam is a building used as a barrier to retaining river water flow to form a reservoir with water reserves. Some of the uses of dams include irrigation, power generation, and flood control facilities. Most dams also have a section called a water gate, which functions to remove unwanted water gradually or continuously. Dams have different water levels every time due to climate and rainfall, This will affect the water discharge in the dam. The water level in the dam can be utilized to produce potential energy which will later be used for electricity generation. The water flow also affects the productivity of the electrical power that can be generated. Therefore, this research will design an open-close regulating weir water gate of a Merangin Dam miniature using a water level sensor and an Arduino microcontroller. The test is carried out using three water level sensors, each water level sensor has three states so in this research there will be 27 states to openclose the water gate system. Based on the test results, the HY-SRF05 water level sensor has an error range of 0,02% to 21,72% where the measured water level has a higher error when the water level is lower. The test of the YF-S201water flow sensor obtained results where the water level in the dam affects the water flow in the penstock, the higher the water level of the miniature dam, the greater the water discharge in the penstock. Water flow sensor measurements obtained the highest water discharge value of 5,43 liters/minute with an error of 6,77% at a water level of 25 cm in the dam. The test results show that the system of opening and closing the regulating weir water gate can work with the desired conditions and results.Key Words: Dam, Regulating Weir, Water Gate
