Abstract

Pengukuran suhu merupakan salah satu hal yang terpenting dalam mengukur kinerja suatu proses pindah panas. Pengukuran suhu biasanya dijumpai di lapangan menggunakan termometer air raksa atau sensor suhu yang memiliki display digital dan dicatat manual. Pengukuran suhu dengan menggunakan cara ini mulai ditinggalkan karena untuk mengetahui kinerja suatu mesin dibutuhkan data yang banyak agar dapat diperoleh kinerja mesin yang akurat. Data logger adalah alat yang sering dijumpai dalam pengukuran suhu baik di laboratorium-laboratium teknik di kampus maupun industri. Data logger merupakan alat ukur suhu yang termutakhir hari ini. Hanya saja data logger yang tersedia di pasaran masih mahal sehingga butuh biaya lebih untuk membelinya. Arduino merupakan mikrokontroler dengan harga yang terjangkau dan dapat disambungkan dengan berbagai sensor dan dapat dirancang layaknya seperti data logger. Metode yang digunakan pada penelitian adalah rancang bangun dengan mengembangkan termokopel data logger. Hasil penelitian menunjukkan bahwa 12 channel termokopel tipe-K dengan penguat sinyal Max6675 dapat berfungsi dan data dapat dikumpulkan ke Micro SD.

Abstract

Rising energy demand and environmental concerns are driving efforts to find alternative energy sources. Photovoltaic (PV)-based power generation is a clean energy solution that continues to be developed for reliable energy supply. This study aimed to analyze global horizontal irradiance (GHI) and evaluate the performance of a PV-based power generation model in Southeast Sulawesi, Indonesia (latitude: -4.002°, longitude: 122.6°). The study was conducted from March to May 2024 using a commercial PV panel with a rated maximum power of 50 Wp. Instantaneous values of GHI, voltage, and electric current were recorded simultaneously. GHI data were closely related to the clearness index (Kt) and the diffuse fraction of solar irradiance. The highest hourly average GHI was observed in March, reaching 1.08 kW/m², while values in April and May ranged from 0.97 to 0.99 kW/m². The system achieved a daily average maximum power output of 34.53 watts and an instantaneous peak of 49.03 watts. The maximum daily efficiency, 12.48%, was recorded in May. Power conversion performance was found to correlate strongly with GHI and Kt values, with greater stability in these parameters leading to more effective energy harvesting. Additionally, solar energy was available for more than 8 hours per day under clear sky conditions during the transitional season. These empirical results provide new insights into PV performance in the region. However, long-term data collection and incorporation of temperature effects, especially in the dry season, will provide power reliability assessment and extend system usability in off-grid applications in the region.

Abstract

A temperature monitoring system is essential in research, especially in the field of energy conversion in the Mechanical Engineering Study Program. One of the most commonly used systems is a data logger; however, its high cost often limits accessibility. An alternative hardware that can function as a data logger is the Arduino microcontroller. This study aims to design and develop a 10-channel temperature data logger system based on a microcontroller using the CJMCU MAX31856 amplifier module. The system integrates a type-K thermocouple sensor, DS3231 RTC module, SD Card module, and OLED display. The research applies both hardware and software design methods, covering component selection, hardware assembly, programming, and functional testing with calibration. The system was tested in a laboratory for three days to monitor the room temperature. The results showed that data from all channels overlapped closely, although minor measurement errors occasionally occurred. Linear regression analysis yielded an R² of 0.99, indicating high accuracy compared with an Autonic temperature controller. Further testing on copper pipes exposed to hot-water heat transfer showed a temperature increase trend, with readings ranging from 27 °C to 39 °C. The system proves reliable, accurate, and cost-efficient for laboratory energy research applications.
