Abstract

The research describes the effect of weights on the calibration results of an analytical balance. This study aims to obtain the uncertainty value of the analytical balance test results by comparison with the standard E2 class weights. The study results can be used to determine the feasibility of the measuring instrument tested through the analysis of the performance value of the scales based on the Limit of Performance (LOP) parameter. The method used is a direct comparison method with E2 class weights. The calibration process carried out in this method includes the measurement of repeatability of readings, deviations from the nominal value indication, the effect of loading not at the centre of the pan, and hysteresis. The data analysis includes standard deviation values, minimum correction values, hysteresis, uncertainty, and LOP. The calibration results show that the reading power of the standard deviation of the load at ½ maximum capacity and full maximum capacity is 0.0042 grams. Deviations at measuring points 20, 40, 60, 80, 100, 120, 140, 160, 180, and 200 grams have a maximum correction value of 0.04995 grams with a maximum measurement uncertainty of 0.006378585 grams and a value of k=2.0 at 95% confidence level. In the performance table of the scales based on the LOP value, it is known that the performance of the scales is in the poor category, and it is more advisable to repair the tool.

Abstract

The most common problem in business and industry today is the optimal allocation of production resources, i.e. providing different levels of productivity in different tasks. The challenge of CV Bintang Jaya is how to optimize working hours according to the working hours of its employees. The purpose of this study is to determine the working time of employees in accordance with the work. The research method used is hungarian using the POM-QM application for Windows. Data are collected through observation, interviews, documentation and literature study. From this study, the best results are obtained based on the work. Employee 1 takes 17 minutes to perform the wood cutting operation, employee 2 takes 35 minutes to make a pattern, employee 3 takes 10 minutes to perform the smoothing operation, and employee 4 takes 10 minutes to perform the assembly operation.

Abstract

Libraries as institutions that manage documents and information services need to be handled professionally by following professional methods and standards. The performance of a library is reflected in its service to users. Therefore, the library needs to always improve the services provided to meet user expectations. To make it easier to measure performance, it is necessary to have an application that processes data and produces reports on the performance of library services. The purpose of this research is to produce an application to measure the performance of library services based on ISO 11620:2008. Applications are made using the Java programming language. From the results of performance measurement, the highest performance value on the user satisfaction indicator is 0.768 and the lowest is on the per capita library staff indicator. The total value of library service performance is 2,142 in the low category.

Abstract

PG. Madukismo is a company engaged in the processing of sugarcane into sugar. In the sugar production process, in terms of raw materials, there are still mixtures or components of sugarcane that are not needed and desired. This is caused by external and internal factors of the company which will certainly affect the quality of the products produced. The purpose of this study is to identify the quality of sugarcane by using Statistical Quality Control (SQC) analysis. This study uses the seven tools method for quality control with the results of the research showing the cause of dirty sugarcane is around 14.44% of the total received sugarcane  due to other components besides sugarcane that are needed such as dry leaves, roots, soil and etc. It was found that the types of quality problems that occurred in sugarcane received by the factory in 2021 were gross 1 (K1) with a percentage of 82.6%, gross 2 (K2) with a percentage of 6.5% and gross 3 (K3) with a percentage of 10.9%. The quality problem of sugarcane received by the factory is caused by human factors (workers), materials, methods, machines and the environment.
