Abstract

Drug inventory management plays a crucial role in pharmacy operations as it directly relates to drug availability, service accuracy, and the prevention of losses caused by expired medicines. However, many small-scale pharmacies still rely on manual recording, which is prone to stock discrepancies, delayed detection of near-expired drugs, and low administrative efficiency. To address these issues, this study developed a web-based drug inventory system implementing the First In First Out (FIFO) method combined with a Supply Chain Management (SCM) approach. The system was developed using the System Development Life Cycle (SDLC), which includes planning, requirements analysis, system design, implementation, and functional as well as user testing. The results demonstrate that the system successfully reduces potential stock recording errors by up to 75% compared to manual methods and improves transaction recording efficiency by an average of 40%. The SCM approach enables the system to automatically issue alerts when stock reaches a minimum threshold and to provide restock recommendations based on demand data. A User Acceptance Test (UAT) involving 10 respondents produced a satisfaction score of 86%, indicating that the system is effective, user-friendly, and beneficial for pharmacy operations. This study concludes that the integration of FIFO and SCM in a web-based drug inventory system improves data accuracy, enhances operational efficiency, and minimizes the risk of expired medicines. Nevertheless, the system still faces limitations related to data security, internet dependency, and its suitability primarily for small-scale pharmacies.

Abstract

The uneven distribution of electrical energy poses a formidable challenge to strategic infrastructure planning and equitable regional development, often hindering sustainable economic growth and exacerbating socio-economic disparities. This issue is particularly acute in a vast and geographically diverse region such as Sukabumi Regency. This study addresses this critical issue by applying the K-Means clustering algorithm to segment 47 sub-districts based on comprehensive electricity customer data from 2019 to 2023, aiming to uncover distinct patterns of energy consumption. The primary novelty of this research lies in (1) its granular application of cluster analysis to sub-district-level electricity customer data for regional energy planning in Indonesia, a previously underexplored area, and (2) the implementation of the results into an intuitive, Streamlit-based interactive web application. This tool serves as a powerful decision-making dashboard for stakeholders, enabling dynamic data exploration and geographical visualization. The methodology encompasses meticulous data collection from official sources, rigorous pre-processing involving data normalization, determining the optimal number of clusters using the well-established Elbow Method, and validating cluster quality with the robust Silhouette Coefficient. The results definitively indicate that three clusters representing Low, Medium, and High energy consumption tiers are the most optimal segmentation. This is substantiated by a strong Silhouette score of 0.6911, which confirms a cohesive and well separated cluster structure. The practical implications are significant, providing a data-driven framework for prioritizing infrastructure investments, enhancing resource allocation efficiency, and supporting the formulation of more targeted energy policies. Ultimately, this study offers a replicable model for other regions facing similar challenges, fostering more sustainable development pathways

Abstract

The application of Large Language Models in the medical domain is often hampered by issues of hallucination and limited up-to-date knowledge. Retrieval-Augmented Generation offers a solution for connecting LLM with factual data, but the quality of RAG output is highly dependent on the accuracy of the information retrieval process. This study aims to analyze the effect of chunk size and embedding model variations on retrieval quality in a medical chatbot system at the Nusa Putra Farmedika General Clinic. The method used is a comparative experiment by testing three chunk size variations (256, 512, and 1024 tokens) and comparing the performance of two embedding models, BGE Small and MiniLM-L6. The evaluation was conducted automatically using the RAGAS framework, focusing on the Context Recall and Context Precision metrics. These findings were implemented into a medical chatbot prototype as a form of functional validation. The results showed an inverse relationship between chunk size and retrieval quality, with a chunk size of 512 tokens producing the best level of information granularity. The BGE Small model proved to be slightly superior to MiniLM-L6 in capturing the semantics of clinical text. The most optimal configuration was achieved by combining the BGE Small model with a chunk size of 512, which produced the highest average score of 0.59, Context Recall of 0.45, and Context Precision of 0.74. This study recommends this configuration as a technical standard for the development of medical chatbot as a foundational step to improve context relevance and mitigate the potential for hallucinations.

Abstract

Effective project management highly depends on selecting the appropriate tools to support team productivity. This study focuses on comparing the performance of two popular project management platforms, Trello and Jira, which are widely used by software development teams. The issue addressed in this research concerns the differences in features and levels of flexibility that often make it difficult for organizations to determine the most efficient tool according to their needs. Therefore, this study aims to objectively evaluate the effectiveness of both platforms and provide recommendations for selecting project management tools that best suit organizational requirements. The benefit of this research is to provide information and references for project managers and software development teams in determining the most suitable project management platform. The method used is a comparative analysis based on the PIECES framework (Performance, Information, Economics, Control, Efficiency, and Service) with a quantitative approach through observation and questionnaire distribution to 30 respondents. The collected data were analyzed based on the six PIECES dimensions to measure the performance level of each platform. The results indicate that Trello achieved higher scores in the Performance (4.8), Economics (4.7), and Efficiency (4.6) dimensions, while Jira outperformed Trello in Information (4.9), Control (4.8), and Service (4.6). Overall, Jira obtained a higher average score of 4.35 compared to Trello's 4.16. In conclusion, Jira is more suitable for managing complex projects that require better control and information management, whereas Trello is more appropriate for small- to medium-scale projects that prioritize ease of use and operational efficiency.

Abstract

The authenticity of diplomas plays a crucial role in maintaining the integrity of the education system and ensuring that recognized academic competencies align with an individual's actual achievements. Diplomas are not merely administrative documents, but strategic instruments in job recruitment and professional qualification assessment. However, with increasing educational mobility, document misuse through diploma forgery is becoming increasingly prevalent, potentially undermining public trust in educational institutions. Currently, the verification process is still largely carried out manually through visual inspection of document elements such as layout and stamps. The reliance on the examiner's experience makes this method vulnerable to inconsistencies and human error, especially when dealing with fake diplomas with visual qualities that increasingly resemble genuine documents. Diploma forgery is a problem that impacts the credibility of educational institutions and the validity of academic data. Manual inspection is often inconsistent and time-consuming. This study develops a model for classifying genuine and fake diplomas using a Convolutional Neural Network (CNN) with a transfer learning scheme. The performance of the ResNet50, VGG16, and MobileNetV2 architectures is comparatively analyzed. Data preprocessing included resizing, normalization, and augmentation. Test results showed the ResNet50 architecture achieved optimal performance with 92.63% accuracy, 92.16% precision, 94.00% recall, and 93.07% F1-score. The system was implemented in a Streamlit-based web application to facilitate the verification process.

Abstract

Despite the importance of environmental control in specialty coffee production, predictive and data-driven systems that connect environmental conditions with coffee acidity remain limited, particularly in smallholder farming contexts. This study aims to design and implement a digital platform based on the Gradient Boosting algorithm to analyze the relationship between environmental factors (soil, topography, and climate) and coffee acidity (pH) levels in Bandung Regency. Through a machine learning approach, the developed model successfully captures complex non-linear relationships between environmental variables and coffee acidity, achieving a high level of accuracy (R² = 0.95) and reducing the RMSE from 0.077 to 0.040 within five learning iterations. The most influential environmental factor affecting coffee acidity was altitude (0.42), followed by soil pH (0.25) and rainfall (0.18). The predictive model was integrated into a web-based system (KopiAsa), allowing farmers to input environmental data and obtain real-time acidity predictions. This platform functions as a data-driven decision-support tool that enhances analysis efficiency, optimizes farm management, and strengthens the competitiveness of local coffee. The results accelerate the digital transformation of the agricultural sector by supporting precision agriculture and promoting more sustainable coffee production practices in Bandung Regency.

Abstract

The order consolidation process, specifically "sweeping orders," is a critical yet often overlooked upstream activity in Supply Chain Management (SCM). At PT Flexo Solusi Indonesia, reliance on manual spreadsheet-based tools resulted in significant data fragmentation, entry errors, and processing delays, which severely hindered downstream logistics coordination and decision-making. This study aims to address this gap by designing and implementing a web-based sweeping order system integrated with SCM principles. Unlike typical inventory-focused systems, this research conceptually shifts the focus to "pre-processing" data synchronization to ensure early-stage supply chain integrity. The system development followed the Waterfall model, supported by a qualitative case study involving in-depth observation and interviews. To ensure research rigor, the system underwent comprehensive black-box testing and workflow validation, specifically evaluating indicators such as data accuracy, process traceability, and the elimination of redundant entry tasks. The results demonstrate that the centralized system successfully enforces sequential workflow validation, thereby mitigating data inconsistency risks and enhancing information flow between the warehouse, production, and shipping divisions. This study concludes that digitalizing upstream order consolidation is a prerequisite for achieving broader supply chain agility. It contributes to existing SCM literature by providing empirical evidence that operational efficiency is contingent upon the accuracy of initial data processing, serving as a scalable digital transformation blueprint for manufacturing SMEs.
