Abstract

This research is a development study on the design of a laboratory scale paint specimen drying oven with a 100 Watt incandescent lamp heat source. This research focuses on the impact of adding aluminum foil insulators on the overall interior of the oven. The aim of the research is to determine the performance of the oven with the main indicators including the maximum temperature that can be achieved, the time required to reach the maximum temperature and the thermal efficiency of the oven. The research method used is testing by applying the principles of the First Law of Thermodynamics regarding Conservation of Energy. Tests were carried out in 11 varying temperature conditions, starting from room temperature of 300 Kelvin. From the test, input data is obtained in the form of electric current, voltage and electric power. Input data includes temperature, heating time and power required to heat the oven chamber. Two input and output data are used to calculate the thermal efficiency of the oven. The final test results were compared with the performance of the oven without an isolator and there was a change in performance. The final results of the research showed that the addition of the aluminum foil insulator was able to increase the maximum temperature of the oven to 330.13 K from 327.57 K before without the insulator. The heating time with the aluminum foil insulator was faster to 2785.6 seconds compared to 3150.56 seconds before without the insulator. . The average thermal efficiency with an aluminum foil insulator is 90.93% from 94.50% without an insulator. Key words:, Aluminum Foil, Insulator, Closed Oven

Abstract

Uji prestasi mesin adalah proses penting dalam pengembangan dan evaluasi mesin, baik itu mesin-mesin yang digunakan dalam kendaraan, peralatan industri, atau peralatan rumah tangga. Ini membantu menghindari kerugian besar yang mungkin terjadi karena kegagalan mesin di lapangan. Untuk mengetahui Perbadingan Prestasi Motor Bakar Dengan Menggunakan Bahan Bakar Pertalite Dan Gasohol E-15. Metode penelitian yang digunakan yaitu perbandingan prestasi motor bakar proses penelitian dilakukan dengan menggunakan motor bensin 4 langkah dimana putaran motor bakar tersebut pada kondisi idle. Kondisi beban dilakukan dengan 6x beban dimana pada setiap beban dan bahan bakar dilakukan 3x pengujian. Beban yang di uji 0 – 300 gram dengan interval 100 gram. Bahan bakar yang diugunakan adalah bahan bakar Pertalite dan. Adapun metode yang digunakan adalah metode statistic dan pengambilan data menggunakan data kualitatif. Prestasi motor bakar dengan menggunakan bahan bakar Pertalite dengan  nilai emisi termal ηth 31,152 %. Prestasi motor bakar dengan menggunakan Gasohol E-15 dengan nilai emisi termal ηth  39,9 %. Dan Perbadingan prestasi motor bakar dengan menggunakan bahan bakar pertalite dan Gasohol E-15 masing-masing memiliki nilai emisi termal yang berbeda. Motor bakar yang menggunakan Pertalite akan memiliki kinerja yang lebih baik dari segi efisiensi termal dibandingkan dengan yang menggunakan Gasohol E-15.

Abstract

Electric power distribution to consumers requires periodic preventive maintenance, including thermal inspection of electrical components. An efficient maintenance strategy can save an industry from potential hazards and devastating losses. Therefore, monitoring the temperature of electrical components is crucial to prevent excessive heat that can lead to fires. This research aims to analyze the detection of electrical component damage in consumer distribution networks using IR Thermography for consumer electric network maintenance. The method involves capturing thermal images of targeted hotspots in various components within the consumer distribution substation. The observed components include transformer 2500 kVA connections, connections in the Low Voltage Main Distribution Panle (LVMDP), connections in the Capacitor Bank, and the Panel Change Over Switch (COS). The acquired data is then processed using Smart View software for analysis, categorization, and recommendations. The results reveal the highest temperatures recorded were 91.0°C in the transformer 2500 kVA, specifically in Phase R, and 71.8°C in the LVMDP panel, in Phase T. These findings indicate that the main causes of temperature rise are load imbalance in the transformer and connection failure in the breaker junction.
