Abstract

The transformer is one of the essential parts of an electric power system. The distribution transformer is a part of the electric power system which plays a vital role in providing electrical energy services to customers. The increasing population and the development of the times make the need for continuous electrical energy. One of the causes of insulation failure in transformers is overheating in the central part. The transformer requires a cooling system to control the heat energy generated. Transformer oil is an insulating and cooling medium for the central part of the transformer. At the time of operation, some disturbances cause the emergence of gases such as carbon dioxide, ethane, and ethylene. The purpose of this study was to design a device for detecting levels of carbon dioxide (CO2), ethane (C2H6), and ethylene (C2H4) dissolved in transformer oil by displaying the ppm (parts per million) value for each gas. Atmega328 microcontroller is used for system control and as a data processor. The data is in the form of a voltage that the ADC microcontroller feature will change. This information is used to calculate the ppm value for each gas. The concentration of this gas will be displayed on the LCD control panel. From the results of this study, the DS18B20 sensor used has an error of 0.00315%, the MG-811 sensor has an error of 10,022, the MQ-6 sensor has an error of 7,918, and the MQ-2 sensor has an error of 9,356. This is indicated by the LCD output, which receives data automatically.

Abstract

Eggplant (Solanum Melongena L) is a type of seasonal vegetable. Eggplants vary in shape and color from white to green to purple. Facts prove that eggplant plants face several threats to their survival and growth, including disease disturbances such as leaf beetles, fruit rot, mealybugs, etc. One way to treat and monitor eggplant plants is to install a camera to capture accurate and fast image data. The image captured by the camera will be digitally processed, which can be used by deep learning methods on object recognition and evaluation system in eggplant plants. Digital image processing can present the color accuracy of leaves, and fruit stems in eggplant plants for solutions and innovations. Digital image processing is the study of image processing techniques. Processed images are still images or images captured with a model camera. In this study, the images taken were of colored leaves attacked by eggplant rot and brown stem rot. The color model used in this study to transform images to color uses the red-green-blue color function. This study uses the YOLOv4 algorithm implemented on a mobile computing device such as Raspberry Pi 4 to select images of eggplant plants captured by a camera. The image data that has been processed will produce results in plant disease diagnoses based on the image captured by the camera. The results will be announced immediately or announced on the Telegram application. We can then detect diseases in eggplant plants and provide immediate preventative measures for diseased plants to maximize yield.

Abstract

Fish is a food in great demand at home and abroad, and apart from its delicious taste, fish is also prevalent because of its health benefits. High protein content and lower fat content compared to other animal protein sources. However, the quality of fish is effortless to decline and spoil. One of the efforts to preserve processed fish so that it can be stored for a more extended period is using preservation. The purpose of preserving fish is to keep fish as long as possible by eliminating the causes of spoilage. There are various types of fish preservation, one of which is drying. Fish drying is a process of reducing the water content in fish to inhibit spoilage. Several factors affect the drying fish’s operation: temperature and airflow velocity. Temperatures that are too large can cause case hardening where the outside of the fish is dry, but the inside is still wet. Then the temperature chosen in this study was 50°C and 60°C with consideration of nutritional standards for dried fish and airflow velocity of 1.5 - 2 m/s. According to SNI 2732.3: 2009, the maximum water content in dried fish is 40%. This system is supported by a type k thermocouple temperature sensor, load cell sensor, tubular heater, fan, solid state relay, keypad, I2C LCD, and Arduino mega. Two input variables must be controlled in a fish dryer: temperature and weight. At variable temperatures, the input is a type k thermocouple sensor. The output is an SSR that holds the tube heater so that the temperature of the fish dryer matches the setpoint temperature. The fuzzy logic method controls the temperature when drying fish does not exceed the set point temperature.

Abstract

Moringa trees are often planted as living fences and along rice fields or paddy fields, and they also function as green plants. In addition, Moringa leaves are also known as an efficacious medicinal plant by utilizing all parts of the Moringa plant, starting from the bark, seeds, and leaves to the roots and undergoing processing operations such as drying, wilting and enzymatic oxidation. The processing of Moringa goes is carried out with a drying process that aims to speed up the processing of Moringa leaves. Tests on drying Moringa leaves are carried out in 2 ways, namely drying without using controls and drying using fuzzy rules, then, from the two tests, a comparison will be made, and conclusions will be drawn. This drying was carried out to determine how much weight loss was in dried Moringa leaves using fuzzy control with a temperature of 60 °C. The overall test results for Moringa leaves were carried out with two tests. Namely, the same results will be obtained from 180-gram Moringa leaves at 60°C and 180-gram Moringa leaves at 50°C. Temperature and time with a decrease in the percentage of age by 50% using fuzzy control. This system is supported by a type k thermocouple temperature sensor, load cell sensor, tubular heater, fan, solid state relay, keypad, I2C LCD, and Arduino mega. Two input variables must be controlled in a fish dryer: temperature and weight. At variable temperatures, the input is a type k thermocouple sensor. The output is an SSR that controls the tube heater so that the temperature of the fish dryer matches the set-point temperature. The fuzzy logic method controls the temperature when drying fish does not exceed the set point temperature.

Abstract

The distribution network is an integral part of electricity distribution, both technically and non-technically, which is very vulnerable to disturbances. This disturbance should be resolved as soon as possible so that it does not interfere with the performance of the electricity distribution and also damage the distribution transformer. In overcoming this disturbance, it can be done by using a safety device and a voltage breaker in each load area. The protection system in the distribution network must work quickly and immediately isolate abnormal conditions to prevent further damage and minimize blackouts. This disturbance should be resolved as soon as possible so that it does not interfere with the performance of the electricity distribution and also damage the distribution transformer. . The effects of this disturbance are changed in voltage, current, temperature, and gas levels in the distribution transformer. So we need a tool that can monitor the condition of the transformer. NodeMCU ESP8266 is a microcontroller that can connect to the internet network, which is used as the central control. The PZEEM-004T sensor is applied as a current and voltage reader. For gas measurement, the MQ-4 sensor is used to measure CH4 gas levels; the MQ-7 sensor is used to measure CO gas levels, and the MQ-8 sensor is used to measure H2 gas levels. The test results found that due to the unbalanced load conditions, there was an increase in temperature in the transformer, which resulted in changes in gas levels. Where from the test, it was found that the lowest gas content was CH4 reaching 113 PPM, CO went 21PPM, and H2 reaching 158PPM.

Abstract

Traditional medicines are ingredients or ingredients in the form of plant ingredients, animal ingredients, mineral ingredients, galenic preparations, or mixtures of these materials, which have been used for generations for treatment and can be applied according to the norms in force in society. Bottle shark (Centrophorus atromarginatus) has good prospects as a producer of liver oil; this fish is easy to catch and occurs in relatively large quantities in Indonesian waters. The catch rate until now is only 39% of its sustainable potential. Bottled shark liver oil contains 90% squalene, Vitamin A, and Omega, which are very useful for the human body as a supplement for heart disease and stomach ulcers and increase stamina and brain intelligence. The rapid Development of technology certainly benefits the people who use it. One example of today's use of technology is applying a technology system for the fisheries sector. This tool works automatically to monitor the processing of bottled shark livers. That way, fishermen don't have to worry about cloudy weather or things that will take longer than processing the shark liver bottle. This Bottle Shark Liver Heater uses temperatures at 31˚, 32˚, 33˚, 34˚, and 35˚. With PID (Proportional Integral Derivative) control, the quality of the Bottle Shark liver can be maintained. This tool is supported by a DS18B20 temperature sensor, Arduino uno, Relay, Ceramic Heater element, DC Fan, LCD 16X12, Power Supply, and Switch. It is hoped that the community, with this automatic system device, can make it easier to manage Bottle Shark Liver Oil.
