Abstract

Thermoplastic polyurethane round belts are widely used for conveyors in various industries, particularly in the food and beverage industry, due to their flexible and abrasion-resistant characteristics. These belts are also popular in manufacturing industries because of their ease of joint. However, a common issue arises when the conveyor belt breaks during the production process. This problem can be attributed to the lack of parameters in the belt joining process at companies. Operators do not have a standard parameter for the joining process. When there is an improper joining operation of an operator, the conveyor belt could fail earlier than the expected operation time. Therefore, the conveyor belt failure results in the loss of production time. This downtime can reach up to 15 minutes, i.e. the time required for the belt joining process. Previous studies have identified temperature and heating time as factors that influence the strength of the joint, especially when using a heating plate. Therefore, this research aims to determine the optimal parameters by varying the temperature and length of heating time in the joining process. Additionally, the research explored the impact of different cutting forms on the durability of the round belt joint. The results of this study indicate that the optimal temperature and heating time combination is 100°C for 3 seconds, resulting in a joint strength of 25,274 MPa. Furthermore, the triangular joint shape proved to be the most durable, with a record of 10,021 cycles.

Abstract

Cassava must go through several manufacturing processes before it becomes chips on the market, including the process of stirring the dough. The stirring process is an important stage in various food industries. In the stirring process, the viscosity change in the dough is influenced by various factors, including the stirring process time and speed in stirring. Research on dough viscosity is important because it is directly related to the quality of the final product. The purpose of this study is to provide recommendations to users, both in the context of using horizontal mixers and the process of making similar products. The type of research used is quantitative research based on experimental methods that aim to test a hypothesis by collecting data that can be measured using statistics, mathematics, and computing. The independent variables in this study are rotation speed (20, 40, and 80 rpm) and stirring time (5 minutes, 10 minutes, and 15 minutes). From these independent variables calculations and data analysis, the optimal setting was obtained using a rotation speed of 80 rpm and a stirring time of 15 minutes with a dough viscosity of 1411.12 PaS. The rotation speed of 80 rpm has more even data or more consistent data compared to the rotation speed values of 20 rpm and 40 rpm.
