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.
