Abstract

Sumber daya lokal guna meningkatkan produksi ikan lele di lingkungan pedesaan dengan memanfaatkan ampas tahu sebagai pakan alternatif. Latar belakang penelitian ini muncul dari tantangan yang dihadapi oleh komunitas pedesaan, yang seringkali menghadapi kendala dalam meningkatkan ketahanan pangan dan ekonomi mereka. Kendala-kendala tersebut meliputi keterbatasan sumber daya, akses terbatas terhadap teknologi modern, dan perubahan iklim yang berdampak pada sektor pertanian. penggunaan ampas tahu sebagai bahan pakan juga membantu mengurangi dampak limbah yang biasanya dihasilkan selama produksi tahu. Hal ini merupakan langkah positif menuju pengelolaan lingkungan yang lebih berkelanjutan.

Abstract

In the world of the culinary industry, competition in the restaurant business is increasingly fierce. Wizzmie must continue to provide the best offers for consumers. People's buying interest in visiting restaurants is not only because of the delicious taste of food and drinks, but also because of the quality of service, comfortable atmosphere and attractive product sales. Researchers are interested in knowing the influence of Service Quality, Store Atmosphere and Visual Merchandising variables on consumer interest and repeat purchases at Wizzmie Rungkut branch. The focus of this research is customers of the Rungkut branch of Wizzmie Restaurant with 110 respondents using the purposive sampling method. Research data was obtained from distributing questionnaires using a Likert scale. The research results show that the Purchase Interest variable has a moderate influence on the dependent variable at 49%, as well as the Repeat Purchase variable at 44.7%. The GoF test result of 0.553 shows that the entire SEM-PLS model is in the high suitability category, so that the data is able to explain the relationship between the variables studied. The variables Service Quality and Visual Merchandising have a significant effect on Purchase Interest, and Purchase Interest has a significant influence on Repeat Purchases, while Store atmosphere has no influence on Purchase Interest.

Abstract

This study analyses the management of raw material inventory at PT Berkah Anugerah Inti Semesta using the Min-Max Stock method. This study aims to identify problems in inventory control that often result in overstocking and understocking, which affects operational efficiency and storage costs. The research methods include observation and interviews to collect data on the use and purchase of raw materials over a period of time. The results showed that the application of the Min-Max Stock method was able to reduce the risk of raw material shortages and significantly reduce storage costs. The determination of safety stock, minimum and maximum stock levels provides companies with clear guidance on how to maintain stock levels. These findings confirm the importance of an efficient inventory management strategy to improve smooth production and the company's competitiveness in the market. This research is expected to be a reference for other companies facing similar challenges, providing insights into effective inventory control practices.

Abstract

This study aims to analyze the quality control of Phonska fertilizer products at Phonska Warehouses II and III of PT Petrokimia Gresik using the Seven Tools and Failure Mode and Effects Analysis (FMEA) methods. Seven Tools are used to identify and map the root causes of production defects through Pareto diagrams, cause-and-effect diagrams, and control charts, while FMEA is used to measure and mitigate potential failures in the production process. The study was conducted during the period April to October 2024 with product defect data collected and analyzed. The results showed that the main defects were no coating oil (34%) followed by mesh (29%), caking (24%), and no color pigment (13%). The implementation of corrective steps based on Seven Tools and FMEA has proven effective in reducing product defects to increase production efficiency and the quality of Phonska fertilizer.

Abstract

PT XYZ is facingproduct quality challenges, especially visual defects in 25 kg pail tubes such as unmold tubes, jetting tubes, and IML on overlapping tubes with unmold tubes reached 55%. This study aims to analyze the main causes of defects in paint tube products at PT XYZ. The methods used are Six Sigma and FMEA with secondary data from the type of 25 kg tube defects in the last 3 months, involving 15 samples with 3 types of defects. The results show that material, mold, machine, and human factors contribute to defects. The Six Sigma value is 3.36, which is below standard. Recommendations for quality improvement are given to reduce the defect rate, with the highest RPN being 240 for unmold tubes.

Abstract

This research aims to minimize waste in the sickle production process at PT XYZ by applying Lean Manufacturing techniques, specifically Value Stream Mapping (VSM) and Value Stream Analysis Tools (VALSAT). The study began with direct observation and data collection of production activities to identify non-value-added activities (NNVA) and waste. Types of waste, including defects, excessive inventory, and waiting times, were identified and analyzed using the 5 Whys method to determine their root causes. Process Activity Mapping (PAM) was employed to classify activities into value-adding, non-value-adding, and necessary non-value-adding categories. Improvements were implemented, such as optimizing material transfers with forklifts, reducing waiting times, and strengthening quality control processes. As a result, non-value-adding activities were reduced from 9% to 0%, significantly enhancing production efficiency.

Abstract

This research investigates the effects of incentives, motivation, and leadership on sales improvement, considering employee performance as a mediating variable, within the context of CV. Sendy Leather. A quantitative research design was applied, employing the Partial Least Squares Structural Equation Modeling (PLS-SEM) method through SmartPLS 4 software. The study involved 44 participants from both the production and marketing departments. Findings reveal that incentives and leadership significantly impact employee performance, whereas motivation does not. Moreover, only performance demonstrates a significant direct effect on the improvement of sales. The direct influence of incentives, motivation, and leadership on sales was found to be statistically insignificant. Additionally, the mediation analysis indicates that employee performance does not significantly mediate the relationship between the independent variables and sales improvement. The values obtained from R-square, Q-square, F-square, and path coefficient assessments highlight that employee performance plays a central role in enhancing sales outcomes.
