Penentuan Waktu Baku Optimal dan Analisis Beban Kerja Pada Bagian Produksi Udang PCDTO-IQF di PT. Indo American Seafoods

Abstract: Factors of labor, working time and workload affect the productivity of an industrial enterprise. Based on these issues, this study aims to establish standard times, worker workloads and the optimal number of workers in the PCDTO-IQF Shrimp production section at PT. Indo American Seafoods using the Stopwatch Time Study method. Research data are obtained directly by measuring the working time in the production department using a stopwatch instrument. The results of the study obtained the total standard time required for the production of PCDTO-IQF Shrimp of 17,089.83 seconds or 4.75 hours. The workload for the production process has 29 processes, there are 11 processes have a workload of more than 100% or normal workload, the rest have a normal workload. Based on these findings, it is recommended that companies increase the number of workers for excess workload and reduce or transfer labor in parts with low workload to other parts that require more manpower.

Keywords: Standard Time, Workload, Optimal Amount of Operator, Stopwatch Time Study, Workload Analysis.

Phytoremediation of several wastewater sources using Pistia stratiotes and Eichhornia crassipes in Indonesia

Abstract: Applying phytoremediation in water purification had a promising prospect for environmental pollution. Phytoremediation is an acceptable, low-cost, easy-to-use, and common wastewater treatment method. This study aims to analyze the potential of phytoremediation for treating a combination of various wastewater in laboratory under environmental control (room temperature, static condition). Pistia stratiotes and Eichhornia crassipes were used in this study and successfully reduced heavy metals i.e. Fe up to 89% and Mn up to 74%. Both of plants also successfully reduce other pollutants such as BOD up to 98%, COD up to 99%, phosphate up to 73%, ammonia up to 70%, nitrite up to 48%, and nitrate up to 91% after five weeks. Bioaccumulation factor informed that the heavy metals contamination in root is higher than shoot. The translocation factor showed that the value is up to 0.9, confirming that these plants are hyperaccumulators. The translocation factor value was less than 1 indicated the low mobility of metals in a different part of the plants. Statistical analysis also showed both plants' relationship in reducing pollutants. Therefore, this study indicated that Pistia stratiotes and Eichhornia crassipes are potential plants for phytoremediation.

Analisis Kepuasan Pelanggan dengan Menggunakan Metode 7P pada Kedai AA

Abstract : Kedai AA is one of the culinary businesses that is experiencing increasingly fierce competition, the competition that occurs is due to the increasing number of businesses that are similar to Kedai AA. In facing this competition, it is necessary to have a marketing mix to be able to encourage the level of customer satisfaction which is able to increase profits for each business. The goal to be achieved from this study is to find out and see how the relationship between the 7P independent variables has on customer satisfaction at the AA store. The approach used in this study is a quantitative approach by distributing questionnaires to customers at the AA shop using a Likert scale. In this study the population used was all customers at the AA Store with a sample of 110 respondents who were chosen deliberately and randomly with the criteria of being a customer of the AA Store. This study uses data testing methods through validity and reliability tests, and the SEM method is the method used to analyze data. The results obtained in this study are product variables have no relationship to customer satisfaction, price has an insignificant relationship, several other variables have a significant relationship, and all variables together have a relationship to customer satisfaction.

Keywords: satisfaction, marketing mix, measurement models, structural models

Eco Design, Internal Environment Management, Just in Time and Organizational Performance: Examining Moderating Role of Trust

Abstract: The prime objective of the present study is to examine the impact of Just in time production, internal environmental management, and eco-design on organizational performance. Furthermore, the moderating role of trust between internal environment management and organizational performance is examined as well. The data for the present study is collected from the customers of the textile industry through convenient sampling. The response rate was 74%. The collected data was analyzed through PLS-SEM. The findings of the study revealed that eco-design and internal environmental management significantly impact organizational performance. Whereas trust moderates positively the relationship between internal environment management and organizational performance. On the other hand, the impact of just-in-time production on organizational performance is not significant. The findings of the present study are helpful for practitioners and decision-makers of the textile industry dealing in the supply chain in developing a strategy to enhance organizational performance.
