Abstract

Accurate inventory recording is a crucial aspect of maintaining warehouse operational efficiency. XYZ Institution is a government agency that operates two distinct types of warehouses: the Central Supply Warehouse and the Environmental Chemical Warehouse. Historically, manual inventory recording in both warehouses has resulted in discrepancies between system data and actual field conditions, with an average data accuracy of only 67% in the Central Supply Warehouse and 44% in the Environmental Chemical Warehouse. This study aims to develop an inventory management application based on AppSheet using the Waterfall method, which includes the stages of design, implementation, and Black Box testing to verify the application's functionality. The application users consist of an admin, who acts as the warehouse supervisor, and end users, namely staff of the Central Supply Warehouse and the Environmental Chemical Warehouse, each with workflows tailored to their respective operational requirements. The test results indicate that the application successfully meets the designed system requirements and is ready for operational use. It is expected that the implementation of this application will serve as an initial step toward the broader digitalization of logistics systems within government institutions

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a strategic role in Indonesia’s economy, including in the garment industry. The subject of this study is MSME X, located in Cimahi City, which specializes in the production of knitted clothing. This research aims to identify production problems, analyze the causes of defects, and design improvement strategies using the Six Sigma method with the DMAIC (Define, Measure, Analyze, Improve, Control) approach. In the Define stage, the main problems are identified through the Critical to Quality (CTQ) approach, which reveals three major types of defects: button defects (39%), stitching defects (32%), and fabric or pattern defects (29%). Next, the Measure stage is conducted to assess process performance using quality indicators. The calculation results show a Defects per Million Opportunities (DPMO) value of 10,968.95 and a Sigma Level of 3.79, indicating room for improvement. The Analyze stage utilizes Pareto and Fishbone diagrams to identify root causes. The Improve stage applies Failure Mode and Effect Analysis (FMEA) to determine improvement priorities. The Control stage involves the use of Statistical Process Control (SPC), regular inspections, and an incentive system. This approach is expected to reduce defect rates and sustainably improve production efficiency.

Abstract

The research objective is to analyze the Technology Acceptance Model (TAM) in measuring QR Code-based object-oriented programming learning multimedia in supporting vocational school students' learning on problem-based object-oriented programming (PBO) material. The TAM model variables used consist of Perceived Usefulness (PU), Perceived Ease of User (PEU), and User Acceptance of IT (UA-IT). The research respondents consisted of 35 students of SMK Negeri 1 Cimahi. The research stages consisted of familiarizing respondents with the use of multimedia, distributing TAM questionnaires, and testing the TAM model using SmartPLS software. The research results show that the average value of the user response questionnaire for QR Code-based PBO learning multimedia is 84.95% in the "Very Good" category. Based on the analysis of the relationship between TAM variables using PLS, it is known that the perceived ease of user variable has a positive influence on the acceptance of QR Code-based PBO learning multimedia, the perceived usage variable has a positive influence on the acceptance of QR Code-based PBO learning multimedia, and the variable perceived ease of use and perceived use. together they have a positive influence on the acceptance of QR Code-based PBO learning multimedia. This research is expected to provide an explanation regarding the use of TAM analysis in learning multimedia
