Abstract

Rapid urbanization and climate change exacerbate the urban heat island (UHI) effect, which challenges environmental quality in tropical cities. However, empirical studies on microclimates in medium-sized cities are still limited. This study aims to analyze variations in air temperature and relative humidity in four types of land use (education, housing, terminals, markets) in Baruga District, Kendari, and identify the contributing factors. A quantitative and experimental field approach was used by measuring temperature and humidity at 30 points using data loggers. Measurements were taken during the day and afternoon for two weeks, then analyzed using descriptive statistics, One-Way ANOVA, and Tukey HSD test. The results showed significant temperature differences during the day (F(3, 116) = 4.21, p = 0.007), with the market area being the hottest (34.50°C) and the terminal being the coolest (32.18°C). Areas with large green spaces (education and residential) were cooler. There were no significant differences in the afternoon or in relative humidity. In conclusion, land use significantly affects the urban microclimate during the day. Impervious surfaces increase temperature, while vegetation plays a crucial role in UHI mitigation. This emphasizes the importance of integrating green spaces into tropical urban planning.

Abstract

The business world is an activity that includes the economy, including production, distribution, and other activities that aim to meet human needs and desires. Welding workshop services are one of the business sectors that continue to grow along with the increasing demand for security and aesthetics in buildings. The canopy functions as a protector from the heat of the sun and rain of a building. Therefore, it is important for welding workshop workers to have reliable skills and knowledge in making canopies. Community service activities aim to provide training and assistance on basic welding techniques on canopies that are useful for improving student competence. The method of activity carried out is a training technique with an allocation of theoretical and practical materials related to the basics of SMAW welding and welding on canopies which are attended by students of the Welding Engineering and Metal Fabrication Department, SMK Negeri 1 Bener Meriah. The results of the activity are as follows: can provide skills for vocational school students to enter the world of work related to the competence of operating SMAW welding machines correctly and can also connect plates on canopy construction using SMAW welding. The results of the material absorption of the student post-test showed a competence of 82%, this shows that students have gained welding skills on canopies and they hope that next year there will be a follow-up program.

Abstract

Data loggers play a crucial role in real-time data acquisition and monitoring across various engineering applications, particularly in renewable energy systems such as photovoltaic (PV) panels. However, existing monitoring systems are often limited by relatively high implementation costs and low flexibility in system development and integration. Therefore, this study aims to develop an Arduino-based data logger that is cost-effective, flexible, and capable of real-time monitoring with high temporal resolution for PV systems. The method employed in this research is a design-and-build approach, which includes hardware design, software development, sensor calibration, and direct implementation on a photovoltaic panel system. The developed system is capable of acquiring data with a one-second sampling interval, enabling enhanced monitoring of the dynamic behavior of PV panels. The parameters measured include the output voltage of the panel and the back surface temperature of the photovoltaic panel. The recorded data are automatically stored on an SD card, supporting long-term data storage and further analysis using software such as Microsoft Excel. The experimental results indicate that the system operates reliably and stably under real operating conditions. The measured voltage ranges from 18 to 20 Volts, while the back surface temperature of the photovoltaic panel varies between 28°C and 51°C.

Abstract

Penelitian ini bertujuan untuk merancang dan membangun sistem data logger pengukur suhu yang dapat digunakan dalam berbagai penelitian yang berkaitan dengan pengukuran temperatur secara akurat dan kontinu. Sistem ini dikembangkan menggunakan platform Arduino sebagai mikrokontroler open-source yang mudah diprogram dan fleksibel dalam integrasi perangkat. Untuk membaca suhu dari sensor termokopel tipe K, digunakan modul amplifier MAX31855 (Adafruit) yang mampu mengkonversi sinyal menjadi data digital dengan akurasi yang baik. Sistem dirancang memiliki delapan channel sehingga mampu melakukan pengukuran suhu secara simultan pada beberapa titik, yang sangat berguna dalam penelitian distribusi temperatur seperti pada studi perpindahan panas atau sistem termal. Selain itu, sistem dilengkapi dengan display OLED berukuran 0,96 inci yang memungkinkan pemantauan data secara real-time tanpa perangkat tambahan. Hasil pengujian menunjukkan bahwa seluruh channel berfungsi dengan baik dan stabil dalam membaca suhu. Data hasil pengukuran tidak hanya ditampilkan secara langsung, tetapi juga berhasil direkam secara real-time ke dalam SD Card, sehingga memudahkan penyimpanan dan analisis lebih lanjut. Dengan demikian, data logger ini memiliki potensi besar untuk diaplikasikan secara luas dalam kegiatan penelitian berbasis pengukuran suhu.

Abstract

The research to determine a effect of microwave power on the quality of red chilies with variations in microwave power during drying. The research parameters are Moisture content, rehydration ratio and specific energy consumption (SEC), changes in color, texture and aroma. The data analysis by analysis of Variance (ANOVA). The input level of microwave power has an effect drying red chilies, which is able reduce moisture water content ranging from 9-12% bb with and time 140-180 minutes. Rehydration ratio ranges from 1.42-1.82 for dried red chilies due to good microwave power treatment for chilies at 200 Watt power treatment. The amount of energy consumption for drying red chilies is smallest in the 300 Watt treatment, which is 466.91 kWhg-1. The characteristics of red chili from organoleptic test were obtained from most color researcher (4.49) in the 250 Watt treatment, the best aroma (4.61) in the 250 Watt treatment and the best texture (4.81) in the 200 Watt treatment, but overall acceptance was most preferred panelists in the 250 Watt power treatment with an acceptance level of (3.89). From this study, it was obtained that there was a variation in the influence of microwave power variations on the quality of red.
