Abstract

A stability test chamber simulates specific environmental conditions and tests a product or material in the manufacturing stage. The tested product or material is then analyzed about its shelf-life estimation related to the state and durability of the product for a certain period. The main parameter that must control accurately is temperature. Programmable Logic Controller (PLC) as an industrial computer control system has been widely used. In this paper, the temperature control system was designed based on PLC and supervisory control and data acquisition (SCADA). The PLC and SCADA would indirectly control the heater. The PLC was feeded from the temperature sensor for real-time temperature inside the test chamber. Received temperature value, compared to the temperature set point. The validation and verification of controlled temperature inside the chamber were also investigated. The system was designed on a miniaturized chamber using commercial PLC and SCADA, Stepper motor, slide regulator, heater, and the temperature sensor PT100. The temperature test point for validation and verification was performed at 35 °C, 45 °C, and 55 °C. The result showed that The PT100 successfully had an excellent response to the temperature test point. The correction value for temperature is as high as 0.6 °C with a deviation of 1 %.

Abstract

Untuk  pembersihan  lahan  dari  tumbuhan  rumput  yang  merimba  disekitar  lahan maka diperlu dilakukan pemotongan rumput. Maka penulis disini membuat protype alat pemotong rumput menggunakan control Arduino. Pemotong rumput Arduino ini  menggunakan  motor DC untuk menggerakan  mata pisau. Kecepatan  motor dc untuk  pemotong  rumput  ini  diatur  oleh  Driver  L298N  yang  deprogram menggunakan Arduino uno yang dapat diatur kecepatannya menggunakan keypad. Metode  dan  prosedur  yang  digunakan  yaitu,  Pengamatan  lapangan,  Perencanaan, Pengumpulan  bahan,  pembuatan  portotype,  pembuatan  program  Arduino  dan melakukan  percobaan.  Hasil  pengujian  dari  penelitian  ini  menunjukan  bahwa prototype ini bekerja sesuai rancangannya, dimana jika manusia menggunakan alat ini  maka  akan  lebih  mudah  mengatur  kecepatan  pemotong  rumput  itu  sendiri dengan menekan keypad dengan otomatis akan muncul di LCD dengan batas PWM nys 225.

Abstract

Abstract− During the Covid-19 pandemic, measuring human body temperature became an important thing as an action to detect early symptoms of Covid-19, in addition as an effort to reduce direct contact and implement social distancing protocols, a study was conducted on temperature measurement which, if an abnormal measuring device will automatically issue the text displayed on the LCD screen and as an early warning. Therefore, this study aims to make an Arduino-based automatic body temperature measuring device that functions like a firing thermometer and the output will be displayed on the LCD screen. In this study, a tool has been designed that can be used to determine the value of human body temperature in a short time and produce an accurate reading value. Using an infrared sensor with the MLX90614 series combined with Arduino Nano and a 16x2 i2c LCD display is the method used to make a body thermometer without physical contact. The research method used is to analyze the results of temperature check data using this tool in several rooms such as air-conditioned rooms, indoors and in open spaces. Keywords: Arduino Nano, MLX90614, infrared, temperature sensor

Abstract

Solar energy, as a renewable energy source, holds significant potential in Indonesia due to its equatorial location, which ensures sunlight throughout the year. However, high temperatures and excessive solar radiation can reduce the efficiency of photovoltaic (PV) modules. The purpose of this study is to design an effective cooling system to improve the efficiency of PV and to develop an IoT-based monitoring system to monitor the system's performance in real-time. This cooling method utilizes a water spray nozzle and DS1820 sensors to monitor both the panel surface temperature and the water temperature. Test results show that PV systems with the cooling system produce an average output voltage of 15.15 V, a current of 2.61 A, and a power of 39.54 W, with a power efficiency of 17.17%. In contrast, PV systems without cooling only produce an average output voltage of 13.52 V, a current of 1.6 A, and a power of 21.63 W, with a power efficiency of 9.38%. The implementation of the cooling system improves power efficiency by 82.89%. The difference in power output between the PV with the cooling system and without the cooling system is 17.91 W.
