Abstract

Drug inventory planning is a crucial aspect in logistics management in first-level health care facilities, as the availability of the right type and quantity of drugs greatly affects the quality of service and patient safety. However, in practice, there are still various problems, such as the mismatch between the amount of stock and the real need for limitations in the use of historical data on drug transactions, and the lack of optimal systems in identifying drug use patterns in a structured and data-based manner. This condition has the potential to cause stockouts and overstock, which has an impact on delays in the delivery of therapy, wasted budgets, and increased risk of expired drugs. In addition, the lack of analysis of drug use combinations also hinders more accurate decision-making in inventory planning and control. Based on these problems, this study aims to apply the Multi-Level Association Rule Mining (MLARM) method in identifying combinations of drug use based on transaction data at health facilities. The results of the study showed that the MLARM method  was effective in identifying patterns of drug use associations at various levels of the hierarchy. At the drug class level, it was found that there was a relationship between hard drugs, over-the-counter drugs, and limited over-the-counter drugs which reflected the use of combinations between drug classes in health services. At the group level of therapy, the association involves analgesics, antibiotics, antihistamines, corticosteroids, and decongestants. Meanwhile, at the level of drug names, specific combinations were found, such as Mms with Kalk, Fe with Paracetamol, Ctm with Paracetamol, and Mefenamic Acid with Amoxicillin. This information can be used to support more optimal management of drug supplies and reduce the risk of stockout and overstock.

Abstract

This study introduces a novel integration of the Mamdani Fuzzy Inference System (FIS) with a web-based recruitment platform for Special Job Fair (BKK) institutions at vocational schools a context not previously addressed in the fuzzy decision-support literature. The current manual process at BKK Jaya Abadi SMKN 1 Bukateja relies on paper-based workflows, causing data loss risks, prolonged processing times, and subjective multi-criteria evaluation. The proposed system uses three input variables  psychotest, interview, and health scores processed through fuzzification, an 18-rule inference base, MAX aggregation, and centroid defuzzification to generate objective recruitment recommendations. Testing on 35 applicant records yielded MAPE = 4.29% and accuracy = 95.71%, outperforming both the manual assessment baseline (MAPE = 12.86%, accuracy = 87.14%) and a simple weighted sum alternative (MAPE = 8.42%, accuracy = 91.58%). A paired t-test (α = 0.05) confirmed that accuracy differences are statistically significant. According to Lewis (1982), the system falls in the "Very Good" accuracy category. The system significantly reduces subjective inconsistencies in candidate evaluation while maintaining transparency and alignment with expert judgment, offering a practical and interpretable approach to automating multi-criteria recruitment decisions in BKK environments.

Abstract

Waste bank data management at the Environmental Agency of Tegal City relied on Google Forms, spreadsheet recapitulation, and manual report compilation, causing data duplication, incomplete reports, inconsistent records, and delayed monitoring; of 187 registered waste bank units, only about 30% submitted monthly reports consistently, and recapitulation took one to two weeks. Previous waste bank information systems mainly supported single-unit operations such as transaction recording and internal reporting, leaving a gap in how a public authority could centrally verify and monitor data from many decentralized units. This study addressed that gap by developing BASMAN, a web-based Waste Bank Management Information System built using the Waterfall approach, integrating master data, operational data, monthly reports, report verification, monitoring, notifications, and data export in one centralized platform with role-based access for administrators and waste bank managers. Unlike prior systems that treated data submission and acceptance as a single step, BASMAN introduced a dedicated agency-level verification stage before report approval. Blackbox Testing confirmed all 35 scenarios passed successfully, and User Acceptance Testing yielded an average score of 4.21 (84.29% acceptance), categorized as highly feasible, demonstrating that BASMAN was both functionally sound and well accepted by its intended users.

Abstract

Good public transport services are determined not only by the operational performance of vehicles, but also by the quality of bus stop facilities that are safe, comfortable and easily accessible to the public. The method used in this study is an analysis of operational performance based on the Decision of the Director General of Land Transportation No. 271/HK.105/DRJD/96 through a survey conducted on board buses, using parameters including load factor, headway, journey time, and vehicle stopping time. In addition, the Importance Performance Analysis (IPA) and SWOT methods were used to evaluate the level of bus stop service based on user perceptions. Data processing was carried out using IBM SPSS software. The results of the study indicate that the operational performance of public transport is relatively good but not yet optimal. Vehicle stopping time and travel time between bus stops are relatively efficient; however, load factors and the distance between buses still show variation, indicating that service regularity is not yet fully consistent. The IPA analysis reveals that the importance score (MIS) is higher than the performance/satisfaction score (MSS), suggesting that bus stop services have not yet fully met user expectations

Abstract

Many small and medium-sized businesses still rely on manual procedures for recording sales transactions and monitoring inventory, creating challenges related to data accuracy, reporting efficiency, and stock control. At PT. ABC, transaction records and inventory updates are managed manually, which increases the risk of recording errors, delays in obtaining business information, and difficulties in monitoring product availability. Based on these conditions, this study aims to develop and evaluate a web-based Point of Sale (POS) system capable of supporting sales activities, inventory management, and operational reporting in an integrated environment. This research adopts a Research and Development (R&D) approach and applies the Waterfall software development model consisting of requirements analysis, system design, implementation, and testing stages. Data collection was conducted through direct observation, interviews with company stakeholders, and analysis of operational documents. The developed system was implemented using web technologies and evaluated through Black Box Testing to verify functional requirements, as well as User Acceptance Testing (UAT) to measure user acceptance and system suitability for operational activities. The evaluation results indicate that all primary system functions, including user authentication, sales transactions, inventory updates, purchase management, and reporting features, operated according to the specified requirements. Furthermore, the UAT assessment conducted with representatives of system users produced a score of 97.5%, indicating a very high level of acceptance and satisfaction. The findings demonstrate that the developed POS system is capable of improving transaction management, providing real-time inventory information, and supporting more accurate business reporting. This study contributes by providing a practical implementation of a web-based POS solution that integrates operational processes and supports decision-making activities within PT. ABC

Abstract

Inventory management at PT. Harmony Abadi Sejahtera was performed manually, resulting in data inconsistencies, delays in stock updates, recording errors, and difficulties in preparing inventory reports. These problems reduced the accuracy and efficiency of spare parts inventory control. This research aims to improve inventory management efficiency and accuracy through a structured stock management approach.A case study research design was employed using primary and secondary data obtained through observation, interviews, and inventory documentation. The research involved identifying inventory problems, analyzing operational requirements, implementing an inventory solution, and evaluating its performance. FIFO (First In, First Out) was applied to regulate stock issuance, while Reorder Point was used to support replenishment. Functional performance was evaluated using Black Box Testing, while effectiveness was assessed based on stock accuracy, recording consistency, and reporting efficiency.The evaluation showed a 100% success rate across tested inventory processes. The proposed approach improved stock recording structure and timeliness, supported FIFO-based stock issuance, and provided inventory information for replenishment decisions. It also reduced recording inconsistencies compared with manual procedures.The findings indicate that integrating FIFO and Reorder Point can improve inventory control and operational efficiency. Further quantitative evaluation of recording time, stock discrepancies, stockout frequency, and reporting time is recommended

Abstract

This study presents a conceptual design of an ESP32-based patient visitor counting system for healthcare registration units and its potential use as a practical learning medium for Medical Records and Health Information (RMIK) students. The Rational Unified Process (RUP) was used to structure the design into inception, elaboration, construction, and transition activities. The resulting conceptual outputs comprise a registration-area layout, system architecture, flowchart, wiring diagram, and 16×2 LCD display design. The proposed architecture uses an ESP32 microcontroller, two HC-SR04 ultrasonic sensors for sequential detection of inbound and outbound movement, a 16×2 I2C LCD for local display, and a buzzer for event feedback, with Wi-Fi connectivity reserved for future IoT-based monitoring. The study does not report experimental prototype performance; therefore, detection accuracy, counting error, response latency, detection distance, and inbound/outbound classification accuracy remain to be validated through physical implementation and repeated trials. The contribution is primarily an application-oriented conceptual architecture connecting automated visitor-flow monitoring in healthcare registration with technology-supported RMIK education
