Abstract

This paper discusses the development of a simple refrigeration system that utilizes a PSU (Power Supply Unit), Peltier TEC1-12706 module, axial fan, and heatsink. This system is designed to provide an efficient solution for cooling limited spaces or electronic devices at an affordable cost. The PSU is used as the main electrical power source, while the Peltier module functions as the main cooling element that utilizes the thermoelectric effect. An axial fan is integrated to improve heat transfer, increase cooling efficiency, and maintain operational temperatures at desired levels. Heatsinks are used as an addition to the heat absorption and distribution process, ensuring optimal system performance. This research involves experimental testing to measure the system's ability to reduce temperatures and maintain operational stability. The experimental results show that data was obtained from the 5th minute to the 30th minute. The average temperature was 18.54˚C in the 5th minute, 16˚C in the 10th minute, 14.88˚C in the 15th minute, 14.88˚C in the 10th minute. in the 20th minute it was 14.34˚C, in the 25th minute it was 14˚C, and in the 30th minute it was 13.78˚C and obtained a maximum COP value of 0.702 and actual COP 0.212. This research contributes to the development of efficient and affordable cooling technology by utilizing components that are easy to access and apply.

Abstract

Indonesia merupakan salah satu negara yang terkenal akan kerajinan tangan, yang berbahan baku dari bambu. Namun, proses pengolahan bambu mayoritas masih dilakukan secara manual yaitu dibelah dan disayat dengan menggunakan pisau tangan, sehingga pada penelitian ini akan dilakukan upaya untuk menciptakan mesin penyayat bambu guna mempermudah industri rumah tangga yang bergerak di kerajinan bambu. Mesin penyayat bambu adalah suatu alat bantu yang berfungsi untuk mengerjakan benda kerja dengan prinsip menyayat. Penelitian ini bertujuan untuk merancang mesin penyayat bambu berkekuatan ¼ horsepower yang dapat digunakan secara efektif dalam industri rumah tangga. Adapun metode yang dilakukan untuk merancang mesin penyayat bambu ini yaitu studi literatur dan analisis kebutuhan, kriteria desain, perancangan konsep, pemodelan dan simulasi, desain detail, pembuatan prototype, dan proses manufaktur. Hasil perancangan menunjukkan bahwa poros 1 memiliki kecepatan 466,67 RPM dan torsi 24,67 Nm, poros 2 dan 3 memiliki kecepatan 311,1 RPM dan torsi 37,01 Nm, serta poros 4 memiliki kecepatan 311,1 RPM dan torsi 37,01 Nm. Sistem gear telah dirancang sebesar 1,5. Simulasi pada rangka menunjukkan tegangan Von Misses maksimal 6,161.194 N/m2, displacement maksimal 0,031 mm, serta safety factor 5,148. Mesin penyayat bambu ini di desain agar dapat menghasilkan sayatan bambu dengan ketebalan sesuai keinginan dan hasil yang cukup banyak dalam waktu yang cukup cepat. Hasil penelitian ini diharapkan dapat memberikan kontribusi dalam pengembangan mesin industri rumah tangga yang efektif dan dapat meningkatkan produktivitas serta kualitas produksi bambu.

Abstract

Heat exchanger is a device used to transfer heat between two fluid systems at different temperatures. In this research, the heat exchanger used is in the form of a shell and tube which studies the mechanism of heat transfer between hot water and cold water both in contra flow. The purpose of this research is to analyze the relationship of heat transfer coefficient with changes in flow regime in shell and tube contra flow heat exchanger. This research was carried out by measuring the inlet and outlet water temperatures for the counter flow configuration, then analyzing the effectiveness calculation using the LMTD method. As a result, the inlet and outlet water temperature values for the counter flow configuration are obtained, then the effectiveness of the heat exchanger is assessed using the LMTD formula where the effectiveness of the heat exchanger for counter flow. The purpose of the research is to understand the heat exchanger system and analyze the performance of the shell and tube heat exchanger.
