Abstract

Sugar production in the country is increasingly unable to meet consumption needs, so sugar imports since the beginning of 1990 continue to increase from year to year. PG Jatitujuh is one of the activity units under the management of PT. RNI (Rajawali Nusantara Indonesia). PG Jatitujuh has a production capacity of ± 4000 TCD and has a land status of HGU is quite extensive, so that where sugar mills with the application of cultivation and milling management patterns in the same management is very potential in improving its efficiency. Evaporation is a process that aims to attach a solution consisting of volatile solvents and non-volatile solutes (Widjaja, 2010). So evaporation is the process of attachment or thickening of liquid solution by eliminating or reducing the moisture content so that a concentrated liquid solution obtained a higher concentration (Fadly, 2021). The research method conducted directly by interviewing field supervisors, foreman and workers at the sugar factory evaporation station, data analysis obtained by measuring the variable evaporation process at the station includes temperature, pressure, and evaporation process.

Abstract

Pipe dies roll is one of the important parts of a pipe roll bending machine that works as a bender or produces a radius of a metal pipe. The lost foam casting method or also called the Evaporative method is a casting method that uses Styrofoam as a more profitable pattern in small and medium industries because of the low initial capital costs with the same production capacity in other casting methods. so that this method is suitable to be implemented in the manufacture of small quantities of products and is able to form flexible and complex cast objects, one of which is in the manufacture of pipe roll dies. Keywords: Pipe dies roll, evaporative, casting

Abstract

This practical work report describes the process of making part bracket finish panel mounting type d74 using PUX 100 stamping press machine and the operating procedures of stamping press machine at PT Persada Selaras Indoensia. The aim is to know directly during the process of making part bracket finish panel mounting type d74, and to know how to operate the stamping press machine. The manufacturing process of bracket finish panel mounting type d74 consists of several stages starting from material checking using SPC440, product design checking, Stamping Press process with four stages of production process (blanking, forming, bending, & Pierching). In addition, this report discusses how to operate the stamping press starting from the machine inspection stage to the stamping press machine setting. Through this practical work report, it is hoped that readers can gain insight into the process of making bracket finish panel mounting type d74 parts and the company's contribution in maintaining product quality. Keywords : Stamping Press, SPC440, Production Process

Abstract

The metalworking process plays a crucial role in the production of machine components, particularly when using a lathe. Continuous innovation is essential to improve the quality of production outcomes. Various methods can be applied, such as selecting the appropriate cutting tool type, determining the depth of cut, and setting the correct spindle speed. The main issue lies in how variations in tool type, spindle speed, and cutting depth affect the surface texture and hardness of the work material during conventional turning operations. This study focuses on the design of a meat chopper blade and a direct examination of the stages involved in its manufacturing process using a manual lathe. The methodology employed to collect data in this research includes systematic observation of the subject to directly ensure the planned investigation, followed by interviews involving direct question-and-answer sessions with technicians and factory managers, as well as a literature review that requires gathering information from relevant books and online resources. The purpose of the meat chopper blade manufacturing procedure is to identify the material used, ensure the proper tools and machines are applied, and describe each stage of the blade-making process. The manufacturing process involves preparing the materials, carrying out cutting procedures, performing turning operations, conducting milling activities, executing drilling processes, applying hardening treatment, and completing finishing operations.In this study, the meat chopper blade is manufactured using ST 37 steel. The process begins with material selection, followed by manual turning, rough turning, finishing turning, center hole boring, deep turning, drilling on four sides, and surface turning. The process continues with blade shaping using a grinding machine to remove excess material, and concludes with the final finishing stage, which includes grinding and polishing.
