Abstract

The industrial world is increasingly advanced, especially in the field of air conditioning technology, this is influenced by the development of information systems that are very fast and dynamic. Industries compete to use technology to make their operations more efficient. The cooling machine has made a lot of progress. Currently, various refrigeration machines are not only used to cool rooms and vehicles, but refrigeration machines are also needed to cool the products produced. One of the advances in cooling machine technology is the AKL5500AV chiller machine. This machine is used to cool PBL plastic products produced. The temperature generated by this cooling machine is unstable, so it affects the production results at PT. XXX. This test is carried out by analyzing temperature indicators and wind pressure indicators at different hours and different temperature conditions. To get maximum results, testing is carried out on the chiller machine. The purpose of this test is to see the performance of the chiller and find out the COP value of the chiller. The test results show that the Coefficient of performance (COP) and Performance factor (PF) values produced are not in accordance with the standards. Chiller's COP value was 3.04 and PF was 4.04. This is of course an input that in order to maintain the performance of the cooling machine, maintenance of the chiller machine must be maintained.

Abstract

Plastic is a polymer material (usually an organic material) that has a high molecular weight in solid form which, when heated slowly, becomes soft and can be shaped an shaped as desired. The aim of this research is to build a vacuum forming machine. This will enable us to package a variety of products used in the home and factory industries and design a vacuum forming machine to meet the needs of the household industry. The operating principle of thermoforming and vacuum forming is used by most small and medium business for various types of product packaging. Thermoforming is a forming process where the properties of plastic fil change to become soft and flexible after going through a heating process and then using preassure or suction which adjust the shape of the mold. The vacuum forming machine consists of 3x3 hollow iron, angle iron, pallet board, 1inch iron pipe, and 2inch iron pipe. The result of the manufacture of this vacuum forming machine include several temperature stages using acryolonitrile butadiene styrene (abs) plastic material 1.5mm, square wood is used for the mold, with a heating temprature of 60-90℃, Maximum test result were obtained at a temperature of 90°C with a vacuum time 120 second.

Abstract

This research was conducted to analyze the performance of the extruder machine on the production quantity and quality of bricks. Analysis shows that the engine transmission uses a type B belt with a belt circumference of 1063.622 mm, so the v belt used by the motorbike has a nominal belt number of 41 inches. From the results of the linear regression of red bricks before being burned with a correlation value of 98.7%, it can be categorized as very strong. The linear regression for red bricks before burning is 0.10 while alpha < 0.05 so it can be concluded that there is no significant influence on variables X and Y. The linear regression for red bricks after burning is 0.07 while alpha < 0.05 so It can be concluded that there is no significant influence on variables X and Y.
