Abstract

In the retail industry, service quality is the main consideration and the quality and completeness of the products offered. The recent conditions that result in declining sales turnover at most of the retail industries in Surabaya prompted this research to be carried out. In this study, an analysis of the service quality in one of the retail industries in Surabaya will be carried out. The method used is the integration between servqual and Kano models. Both methods are used because they are proven to show good results in previous research. The results obtained from this study are that several service attributes need to be improved because of the negative satisfactions value result. Those attributes are the availability of items location instruction. Item price should be matched with the price tag, standard pricing, safety parking, safety shopping, good salesperson, and careful cashier.

Abstract

Project management is a process of activities to manage organizational resources owned by the company to achieve certain goals. The Terbangi Besar-Kayu Agung Lampung toll road construction project is a project that must be completed in a short time. This study has a purpose to evaluate the performance of the construction project of the Terbangi Besar-Kayu Agung Lampung toll road using the PERT and CPM methods with a toll road length of 189.2 km (117.6 miles). Based on the results obtained by using these two methods, the project completion time which was originally 238 days can be completed in just 119. There are several alternative proposals. The alternative proposal by adding work shifts that have crashed 32 times has an optimal cost of IDR 39,154,229,627.03 and an optimal time of 119 days. While the alternative of increasing the capacity of the equipment produces an optimal time of 189 days and an optimal cost of IDR 39,205,747,076.44 with the crashing process reaching 12 times of crashing. The Toll Road Development Project Planning is scheduled to have a normal time to work for 238 days at a total cost of IDR 39,349,097,164.38.

Abstract

The current competition in the food industry encourage companies to be able to produce products that are diverse, in a good quality, and in a timely manner to meet the company's production targets. PT XYZ is a food company in Indonesia. To be able to meet production targets, companies must adjust their production capacity by utilizing their workforce. However, the problem is that there are so many variables involved in the system so that the problem becomes more complex and hard to solve. Therefore in this study, a dynamic system approach is used to be able to see the interactions between variables in the system using Vensim software. Based on the research that has been done, the values ??of E1 < 6% and E2 < 2.5% indicated that the data used in this research is valid in other words the model used has represented the real system conditions. From the research, the best result is to gradually increase the installed capacity so that there is no over production occured. Using this scenario, the availability of raw materials for is 5901 boxes.

Abstract

PT. XYZ is a company operating in the food industry, with its main product being instant noodles. In its production process, not all products produced meet the quality standards set by the company. This indicates the presence of defective products, often due to errors in factors such as machinery or human resources, among others. Initial observations reveal that there are still many defects in their products. Quality control at PT. XYZ is done manually by the owner, who supervises each production cycle. Defects in PT. XYZ's products are categorized into three types: torn noodle packaging, crushed noodles, and torn seasoning packaging. Therefore, improvements are needed in the production of instant noodles by PT. XYZ. This research aims to improve the quality of production in the company and to explain the approach to analyzing the defect rate of instant noodles using Six Sigma and Kaizen. The results obtained using the Six Sigma method in the DMAIC analysis (Define, Measure, Analyze, Improve, Control), showed that product quality testing during the instant noodle production process resulted in 3238 failures. The Defects Per Million Opportunities (DPMO) value was 41172.88, which, when converted to a sigma level, was 3.23, indicating that the sigma level was at the industry average in Indonesia. This suggests that there is a potential for 41172.88 defects per one million productions, showing an inconsistent pattern of DPMO and sigma achievement. This indicates that the production process has not been managed accurately and requires improvement, particularly in the quest for zero defects.
