Abstract

CTS is arranged in outer muscle problems. This infection is brought about by pressure of the middle nerve at the wrist. Occupational factors are work- related risk factors, such as working quickly, repetitive movements, work stress, work that uses a lot of wrists and vibrations. The motivation behind this study is to decide the impact of word related elements to CTS frequency on regulatory specialists. This study uses cross sectional design with 35 respondents as sample. To determine hand posture was carried out by observation and interpretation with RULA, measurement of repetitive motion use a stopwatch, and work stress use Stress Diagnosis Survey. Utilize the Phalen's Test and the Boston Carpal Tunnel Questionnaire to determine the incidence of CTS. The aftereffect of prescreening on managerial specialists uncovered that 40% laborers are positive for CTS. While the analysis uses binary logistic regression to determine the influence of occupational factors to CTS incident. Variables that influence CTS are repetitive motion of using mouse (p=0.005), repetitive motion of typing (p=0.027), and work stress (p=0.027). Therefore, it is necessary to give recommendations based on related variables (repetitive motion and work stress) in order to minimize the occurrence of CTS.

Abstract

Quality Management is one of the activities of a foundry manufacturing company in order to develop and continue to manage the business processes in it. One of the VS casting products has a production period of 1 month from the injection moulding process to the machining stage using CNC lathe and milling. In quantity, many products have quality levels that are not up to standard. Based on data from the beginning of the year in February 2023, observations were made for 1 month to recap the production results in the finishing department of the machining section. It was recorded that there were 40% defective products out of a total of 686 pcs. After making improvements using the DMAIC method, the finished good machining target has increased to 52%. Coupled with the help of Minitab statistical software in calculating the sigma value from 2.09 can change to 2.2 with an initial DPMO of 275,520 down to 261,662. The calculation is also equipped with a cause analysis using the 4M + 1E factor and the implementation of improvements to each cause. The writing of this paper also provides advice on using form control to anticipate the loss of quality in VS products.

Abstract

East Java Province has abundant potential in the fisheries sector, both production factors and geographical conditions of the sea. The production factor of capture fisheries in East Java in 2017-2022 tends to increase but contributes little to the GRDP of East Java. The variables used in this study are the number of fishermen and GRDP of districts/cities in East Java. The study aims to analyze the effect of the number of fishermen on GRDP in East Java and analyze the differences in each subsector. The research used a saturated sample technique, with panel data regression as the analysis test. The study is divided into two models, namely model I (marine fisheries) and model II (inland public waters). The results showed that in both models the number of fishermen had a significant positive effect on GRDP. This is because the increasing number of fishermen will increase the catch of fish and the income earned. The increased income will contribute to the economic growth of a region or what is referred to as GRDP. Marine fishermen tend to have more numbers than inland public water fishermen because a larger area will require more labor.

Abstract

In the past one year, the problem of critical defects is the most dominant problem. With a percentage of 46% of all problems. This study aims to determine the factors that cause the bottle to leak and to find an effort to reduce the level of leaky bottles in the blow molding department's bottle production process. The method used in this study is Six Sigma which includes five stages of analysis, namely DMAIC (Define, Measure, Analyze, Improve, and Control). The approach used to improve the process. Each stage of DMAIC is done by carefully analyzing and maintaining the process. The results of this study indicate that the factors causing leaky bottles analyzed with FTA are problematic valves, air settings are not normal, blow pins are not centered, loose switch limit bolts, no checking rules, new technicians, and no defective mouth product reference . While the effort that must be done is changing the valve, the central pressure is increased to 7.5-8 bar, setting the blow pin to the center, changing the limit switch bolt, making the rules at the beginning of shift shifts, holding regular training for technicians, and making leaky product references.
