Abstract

Research aims to analyze the application of Six Sigma in order to support the improvement of fabrication process capabilities. The improvement of fabrication process capability is expected to have an impact on the overall reduction in production and logistics costs, which we called a supply chain costs. A case study at a fabrication company was carried out to calculate the capability of the fabrication process and make improvements by applying the Six Sigma method. In this case, product quality that produced from the fabrication process largely determines the supply chain costs incurred by the company. Minitab software is also used in processing and analyzing data. This research shows that improving the fabrication process capability has an impact on reducing product defects so that supply chain costs are lower. Research provides an illustration for the industry that continuous improvement with the aim of reducing the occurrence of product defects will not only have an impact on reducing production costs, but also on logistics costs. As the Six Sigma method implemented, the number of defective products has decreased from 8 pcs per 100 pcs Collar products to 0 pc from 100 pcs Collar products. Fabrication process capability of PT BMT reaches Cpk 5.94 with the sigma value 6 Sigma. The implementation of the Six Sigma method also has a positive impact on overall supply chain costs, with a reduction in supply chain costs of 7.6%. So that PT BMT has a fabrication process that is more effective and efficient.

Abstract

The purpose of the research is to analyze and find out the effect of integrated marketing and marketing relationship to the airlines customers’ loyalty using Structural Equation Modelling (SEM). The population of the research was airlines passengers of Soekarno Hatta Airport and sample was taken of 105 respondents. The data was collected using questionnaire, interview, documented study, studied variables by using Likert Scale. The questionnaire result was analyzed using Lisrel (statistics software). The result from hypothesis test is parsially the integrated marketing variable does not show significant effect to loyalty variable that can be seen from the score t = -0.99 < -1.96. Based on t score t = 8.27 > 1.96, relationship marketing is the variable that give strong and significant effect to loyalty variable. Simultaneously, independent variables, relationship marketing dan integrated marketing, give positive and significant effect to loyalty variable. Based on 11 criteria of GOF / Good on Fit model, the model in this research has shown good modeling which means the measurement model obtained from the data is in accordance with the research hypothesis due to 8 out of 11 criteria fullfilled

Abstract

The Independent Village in Marunda, which is located on the coast, has the potential as a potential shark producer to be developed. Markets that need to be open are wide enough, including the need for catering, and modern markets such as Makro, Transmart and others. To enter a wide market requires special attention, especially with product health and hygiene (hygenic) and product quarantine. The purpose of this activity is to improve the welfare of the community in Marunda village, Cilincing sub-district, North Jakarta through socialization on how to maintain product health and hygiene (hygenic) and product quarantine. This socialization was carried out offline at PT XYZ which was attended by the owners, employees and students of ITL Trisakti in the context of implementing MBKM. The results of the socialization are expected to be carried out to expand the market and increase the amount of production.

This study uses the AHP-TOPSI (Analytic Hierarchy Process – Technic for Order of Preference by Similarity to Ideal Solution) method where the Likert scale is used as a comparison. Problem solving is done by making research using qualitative research methodology with descriptive elaboration.  Data collection is done by giving or making questionnaires to get the weight of the assessment carried out by inferring with AHP and Likert from the data collected through questionnaires shared where the respondents came from respondents who have dedication and direct links as well as have the capability to provide vendor performance assessments. The results of the research that were tested from the level of consistency were divided into 5 criteria, namely, Price, Safety, Service, Reliability and Reputation and from the results of the qualitative calculation method by distributing questionnaires from 10 experts for Five existing vendors with adding quantitative approach in TOPSIS, V.2 out as priority vendors.

Abstract

This research presents a comprehensive framework for utilizing information technology (IT) to enhance the effectiveness of humanitarian logistics management. By employing value stream mapping, we conducted a thorough analysis of the current (AS-IS) business processes involved in humanitarian response. Through this analysis, we identified significant inefficiencies and bottlenecks that hinder the timely delivery of aid. Addressing these challenges, we propose a new (TO-BE) business process model that incorporates the implementation of a warehouse management system (WMS). This innovative approach is expected to significantly reduce lead times by 25%, thereby improving the overall efficiency and effectiveness of humanitarian operations.The proposed framework outlines the key steps and considerations for integrating IT solutions into humanitarian logistics, providing a valuable guide for organizations seeking to optimize their response capabilities and save lives.
