Abstract

Into several stages, namely design, material selection and manufacture. The design uses solidworks 2013 software which includes frame design, tank design, Helical-Coil heat exchanger design and the stage of uniting components designed to be able to flow refrigerant heat to water. The stage of making the tool follows from the design that has been made, namely the frame using angle iron (L) with dimensions of 750mm x 390mm x 1500mm, the tank uses a stainless steel plate and the addition of PCM around the tank with a capacity of 60 liters and an overhaul of the compressor outlet flow that is routed to the Helical-Coil heat exchanger made of copper with a diameter of 6.35mm with APK dimensions 150mm x 300mm or half of the tank height. From the test results, ACWH can work well as evidenced by not using PCM, increasing water temperature with the addition of PCM reaching 60.25 oC within 7 hours of testing, while not using PCM water temperature reaching 60.17 oC within 10 hours.

Abstract

Plastic is a synthetic polymerization product material, plastic is very difficult to decompose where the degradation of the plastic itself usually takes decades by nature. According to the Ministry of Environment and Health and the Ministry of Industry, the amount of waste in 2016 reached 6.25 million tons per year. This makes plastic waste one of the causes of environmental pollution. Recycling plastic waste is a solution to the problem of plastic waste which is increasingly polluting the environment. Realizing the importance of plastic recycling. Then a recycling tool will be made or changing the shape of plastic to be more useful, such as recycling plastic into paving blocks. Recycling plastic waste into paving blocks is expected to be a solution to environmental pollution due to plastic waste. Therefore a paving block printing tool made from plastic and sand is designed and produced which can reach a temperature of 397 0C, the paving block printing machine can make paving blocks made from PVC (Polyvinyl Chloride) plastic waste or plastic pipes. This tool can melt as much as 1.2 kg of plastic waste, namely 1 (one) paving block made from plastic waste and sand. The resulting paving blocks are in the form of bricks with sizes according to SNI Number 03-0691-1998 with dimensions of 10 cm x 20 cm x 6 cm.
