Abstract

Capsicum Annuum L. is one of the vegetable commodities that have high economic value in fulfilling Indonesia's domestic needs with an area of chili harvest of around 11,400 ha per month. One of the stages in the cultivation of chili plants is the process of transplanting after sowing, namely the condition of the seeds having 4-5 permanent leaves. The impact if it is not immediately transferred is that the plant does not have enough adaptation period in completing its vegetative growth so that the plant quickly ages and enters the generative stage. Digital image processing can be applied to the identification and calculation of permanent leaves of large chili plants with a deep learning approach. One method that can be used is You Only Look Once version 4, which is the development of a convolutional neural network in object detection in the form of boundary box prediction results with a CSPdarknet53 backbone. The YOLOv4 model is integrated with the Raspberry Pi 4 Model B mini computer and sends notifications via the Bot feature in the Telegram application. The image dataset used is 135 pieces with 1409 samples for permanent class and 1945 samples for the young class. This system was successfully implemented with the identification and calculation accuracy value of 92.85% and the inference time value for the detection of one plant was 11.88 seconds and for sending notifications was 25.29 seconds.

Abstract

In this final project, we describe the study of reconfiguring the distribution network at the LG-04 feeder at the Lancang Garam substation, Lhokseumawe, to improve the performance of the distribution system. The focus of the parameters considered includes continuity, voltage, and power loss. The reconfiguration is to change the initial network topology which is in the form of radial into a loop. After reconfiguration, the calculation of power flow, voltage drop, power loss, and short circuit calculation is also carried out which becomes a reference for whether or not the quality of the network is good. The results of the simulation of the existing conditions show that continuity is not good, after reconfiguration and fault testing, the network does not experience blackouts like the network before reconfiguration. The power loss generated in the network after reconfiguration is 0.507 kW or a decrease of ±84% from the previous form of the network.

Abstract

Energi listrik konsumen secara berkelanjutan maka peralatan sistem kelistrikan harus dijaga agar dapat beroperasi secara optimal, salah satunya peralatan kelistrikan adalah transformator. Kelangsungan operasional transformator sangat tergantung dari umur dan kualitas isolasinya, salah satunya kualitas minyak transformator. Sebagai insulasi dan juga pendingin, maka perlu dilakukan perawatan transformator agar dapat beroperasi dengan normal tanpa adanya gangguan. Salah satu cara untuk mengetahui kondisi transformator adalah dengan mengamati kondisi minyak transformator. Pengamatan kondisi transformator dilakukan dengan salah satu cara yaitu pengujian kandungan gas pada minyak transformator, dimana pada saat pengujian kandungan gas pada minyak transformator dilakukan juga pengujian suhu pada minyak tersebut. Setelah pengujian dilakukan maka dilakukan diagnosis kondisi minyak transformator sebagai salah satu cara yang paling efektif dalam memantau kondisi transformator.

Abstract

Abstract The distribution transformer is part of the distribution system, the transformer that is closest to the customer, if there is a problem with this transformer, the customer will immediately feel it. So to ensure the availability of electricity distribution, this transformer requires periodic maintenance and service. Detection of distribution transformers by detecting an imbalance of voltage and oil temperature in the transformer. To get the voltage and current values using the PZEM-004T sensor and for the transformer oil temperature value with a temperature of DS18B20 which will be forwarded to the LCD screen via the Arduino Uno platform. For the average value of the voltage obtained is 65V. this tool successfully reads the output of current, voltage and transformer oil temperature well with an average error of 0.74% at the maximum current reading in phase T. The system can provide information if there is a voltage imbalance, for voltage imbalance the largest error percentage is obtained. in Phase R of 6.31%. The voltage imbalance should not be more than 2.5% so that the voltage value that is read on the R phase exceeds the capacity of the voltage imbalance which causes a voltage imbalance disturbance in the T phase and the display of the value that is read on the LCD will appear the words "Not Normal Voltage" and marked with his life buzzer.

Abstract

In this era of globalization, science and technology has developed rapidly, especially in the industrial world. As for science and technology that is beneficial to industry, namely for components of the production process, one of which is Valve control. This technology is used to modify the fluid flow or pressure rate in a process system by using power for its operation. The application of this control valve is used to control a pressure rate or quantity, such as the amount of oxygen gas content (O₂) and carbon dioxide (CO₂) in fruit and vegetable plants. In the research that has been carried out on the carbon dioxide (CO₂) process using a porous fiber membrane contactor, the gas model is absorbed in a pure state at cold room temperature. In this study, it is still an obstacle when applied in the field because there are many factors that have not been taken into account, so in an effort to control the wasted gas, an electric gas valve control system device is needed which is designed to determine the value of wasted gas. This system is designed with valve components, servo motors, solenoid valves, Arduino uno, and relays, where all these components are built and programmed with Arduino uno microcontroller. The results of the test are carried out to determine the level of accuracy of each input to the control valve and to determine the value of the gas wasted at the degree of opening of the valve. The test results on the ten forms of angular movement are when the valve works and opens at a movement angle of 0° to the movement, the valve opens at 0%. When the valve works and opens at an angle of movement of 10° to rotation, the valve opens by 11.1%, and when the valve works and opens at an angle of movement of 20° to 80° to the movement, the valve opens by 22.2% to by 88.8%, then when the valve works and opens at an angle of movement of 90° to the movement, the valve opens by 100% or fully opens. The benefits of this research in the performance process of production technology in industry are to meet consumer demand by producing safe, minimally processed, additive-free, and stable quality food.
