Abstract

The purpose of this research is to design and test the performance of a water heater unit that works based on the exhaust heat of the ½ PK Split Air Conditioner condenser which will be used as a power source to heat water with a capacity of 60 litres based on standard hot water temperature. for bathing at 40-45 oC according to the type of use SNI 03-7605-2005 concerning procedures for planning plumbing systems. It is hoped that this research can serve as a guideline for designing a water heater derived from an exhaust heat condenser using a Helical-Coil type heat exchanger. This research uses descriptive research with a quantitative approach. Descriptive research in this study is intended to obtain an overview and information regarding the utilization of an exhaust heat condenser with the addition of a water helical coil heat exchanger and the working process of an air conditioner water heater that utilizes condenser waste heat to produce hot water that can be used for bathing needs. From the test results, the water heater can work well as evidenced by an increase in water temperature reaching 44.40 C in 70 minutes. The energy value in the form of heat that can be utilized by adding a water heater is 1.14785 kJ/second, with a water heater efficiency of 76.23%. Thus the utilization of the air conditioner condenser wastes heat energy and is quite effective for heating water. To be able to save water use for household, business, industrial and other needs that use Air conditioners as air conditioning.

Abstract

PT. Teupin Lada adalah perusahaan swasta yang bergerak dalam bidang perkebunan sawit. Dan berkembang menjadi Pabrik Pengolahan Minyak Kelapa Sawit (PMKS). PT. Teupin Lada memiliki 100 karyawan. Permasalahan yang terdapat di PT. Teupin Lada masih ada karyawan yang tidak memperhatikan prosedur kerja, tidak menggunakan APD lengkap seperti tidak menggunakan helm proyek, sepatu safety, masker, kaca mata dan ear plug. Adapun tujuan penelitian ini menganalisis dan memberikan solusi terhadap risiko kecelakaan kerja pada perusahaan Pabrik Pengolahan Minyak Kelapa Sawit (PMKS) di PT. Teupin Lada sesuai Standard Operasional Prosedur (SOP). Metode yang dipergunakan adalah Hazard Identification And Risk Assessment (HIRA). Kesimpulan dalam penelitian ini adalah temuan risiko kecelakaan kerja pada proses produksi merupakan jumlah risiko kecelakaan kerja yang dimiliki oleh masing-masing proses produksi di PT. Teupin Lada. Jumlah kecelakaan kerja yang terjadi yaitu 10 risiko pada Boiler dengan level risiko Rendah 1, Sedang tidak ada, Tinggi 3, Ekstrim 1. Kemudian jumlah kecelakaan kerja yang terjadi yaitu 5 risiko pada Workshop Mekanik dengan level risiko Rendah tidak ada, Sedang 1, Tinggi 3, Ekstrim 1. Kata kunci : K3, HIRA, Risiko Kecelakaan Kerja.

Abstract

This study focuses on assessing a composite material that uses pearly leaf reinforcement and a polyester resin matrix as a construction material for energy-efficient automobile bodies. The traction strength test and impact resistance test of thorn panda leaf fiber are conducted to evaluate the difference in fiber direction, namely induced and random. This discovery is anticipated to be advantageous for the development of energy-efficient automobile bodywork. The highest traction force recorded is 2199.63 MPa in the random fiber direction, whereas the lowest traction strength is 2077.43 MPa in the fiber direction. The pulling force increases when the direction of the fiber aligns with the pulling manner, resulting in more force. The impact's greatest absorbent energy strength is 0.623 j in the direction of the fiber, while the least absorbent energy strength is 0.595 j in the direction of the random fiber.
