Abstract

This study aims to address management obstacles in the Plantation Crops Agribusiness (ATP) major at SMKS Bakti Agro Mandiri, where practices are currently conducted conventionally using physical logbooks. The primary issues identified include slow harvest data recapitulation, risks of inventory data loss, and suboptimal utilization of student gadgets for productive field activities. The system was developed using the Agile Software Development Life Cycle (SDLC) method, selected for its flexibility in accommodating iterative user requirement changes, with a relational database designed in MySQL via phpMyAdmin. The results demonstrate the creation of a mobile-friendly, web-based Garden Management Information System (Simagri). This system effectively integrates planning, inventory, and real-time harvest reporting functions. The study concludes that the implementation of Simagri significantly improves garden operational efficiency, minimizes the risk of losing planting history, and optimizes student smartphone usage as a transparent productivity instrument.

Abstract

The development of information technology has encouraged companies to implement fingerprint-based attendance systems to improve the effectiveness and accuracy of employee attendance recording. However, in its implementation, several problems are still found, such as system errors, delays in fingerprint reading, and technical disturbances that can affect user convenience. This study aims to evalUATe the fingerprint-based attendance information system at PT GIRVI MASS using the User Acceptance Testing (UAT) method and the PIECES Framework. The UAT method was used to measure the level of user acceptance toward the system, while the PIECES Framework was applied to analyze system quality based on the aspects of Performance, Information, Efficiency, and Service. This research used a quantitative method by distributing questionnaires with a Likert scale to 30 respondents who were employees of PT GIRVI MASS. The collected data were analyzed using the weighted mean method and UAT percentage calculations. The results showed that the system obtained a UAT percentage score of 82.6%, which falls into the “Very Good” category. The PIECES Framework analysis also indicated that the system was able to improve the attendance process to become more effective, efficient, and user-friendly. Nevertheless, several technical issues were still identified, especially related to system stability and error handling. Therefore, the company is advised to conduct regular maintenance and system development to further improve system quality in the future

Abstract

Inventory management at the Frisian Flag Distributor requires a system capable of determining procurement priorities accurately and objectively. Inaccurately determining which items should be prioritized often leads to problems such as overstock, understock, and the risk of losses due to expired goods. To address these issues, a decision support system using the MOORA (Multi-Objective Optimization on the Basis of Ratio Analysis) method with ROC (Rank Order Centroid) weighting was implemented. ROC weighting is used to determine the importance of each criterion based on priority order, while the MOORA method is used in the normalization process, calculating optimization values, and determining alternative rankings. The criteria used in the decision-making process include sales level, remaining stock, market demand, product price, and expiration date. Data processing results show that the combination of the MOORA and ROC methods can produce a systematic, measurable, and objective order of stock procurement priorities. The designed system can assist distributor management in making faster and more accurate decisions. The implementation of this method is expected to improve inventory management efficiency and minimize the risk of losses due to errors in determining procurement priorities.

Abstract

Skin diseases are among the most common health problems affecting the community. This study aims to develop a skin disease classification system based on symptoms using the K-Nearest Neighbor (KNN) algorithm and to provide treatment recommendations. The dataset used consists of 405 records containing disease symptoms, disease location, disease shape, disease name, and treatment recommendations. Text-based symptom data were transformed into numerical representations using the Term Frequency-Inverse Document Frequency (TF-IDF) method before the classification process was carried out using the KNN algorithm. The experiments were conducted using K values of 3, 5, and 7. The results showed that the best performance was achieved with K=7, obtaining an accuracy of 90.12%, a precision of 0.91, a recall of 0.93, and an F1-score of 0.91. Meanwhile, K=5 achieved an accuracy of 88.89%, and K=3 achieved an accuracy of 87.65%. Furthermore, the system was successfully implemented using Streamlit, allowing users to interactively classify skin diseases and obtain treatment recommendations based on the symptoms entered.

Abstract

Driver scheduling is an important process in public transportation operations because it is related to workload distribution, fleet readiness, and service quality. At Koperasi Pengangkutan Umum Medan (KPUM), driver scheduling priorities are still determined conventionally, making decisions potentially subjective and difficult to trace quantitatively. This study aims to develop a web-based Decision Support System (DSS) to determine driver scheduling priorities using the Weighted Product method. The assessment criteria consist of route mastery, discipline, work experience, working time, and health condition. Data were obtained through observation, interviews, and internal assessment of ten active drivers. The analysis process includes weight normalization, construction of compatibility ratings, S vector calculation, V vector calculation, and alternative ranking. The calculation results show that alternative A8, Binarto, obtains the highest preference value of 0.1311, followed by A5 with 0.1265 and A9 with 0.1234. Functional testing indicates that the login feature, data management, calculation process, and ranking display run according to the test scenarios. The proposed system can assist KPUM in preparing scheduling priorities in a faster, measurable, and more transparent manner.

Abstract

Southeast Aceh Regency is one of the regencies in Aceh Province that has many attractive natural tourism destinations, but information about these destinations is still very limited and not easily accessible to the general public. Information dissemination that is still carried out conventionally, such as through word of mouth, magazines, and flyers, causes tourism potential not to develop optimally. This study aims to design and build a Web-Based Nature Recreation Travel Package Information System in Southeast Aceh that can facilitate the public in accessing natural tourism information while making online travel package reservations. The development method used is the waterfall method which includes the stages of requirement, software design, implementation, integration, and maintenance. The system was built using PHP, HTML, CSS, Bootstrap framework, MySQL database, as well as Visual Studio Code and Sublime Text editors. The developed system features a home page with a list of tourist destinations, travel package pages, hotels, souvenirs, contacts, user login and registration, package ordering, payment proof upload, ticket printing, and an admin dashboard to manage all content. The results show that this web-based information system successfully presents comprehensive natural tourism destination information from Southeast Aceh and allows users to make online travel package reservations, thereby increasing accessibility for tourists and potentially improving the local economy.

Abstract

The selection of cleaning service foremen in government institutions is often subjective, leading to inconsistent performance evaluations. This study aims to design and implement a Decision Support System (DSS) using the ELECTRE method to objectively select the best foreman at the Indragiri Hilir Regent's Office. The system employs an outranking mechanism with concordance and discordance index analysis to systematically eliminate candidates failing to meet managerial thresholds. Five evaluation criteria were applied: leadership, discipline, responsibility, loyalty, and communication skills. The results show that the ELECTRE-based DSS successfully identified the most suitable candidate by eliminating alternatives with critical weaknesses, producing transparent and auditable recommendations. This system reduces cognitive bias in decision-making and provides a strategic instrument for improving public service standards within the regional secretariat. The findings confirm that ELECTRE is effective for operational staff selection where minimum competency thresholds are non-negotiable.

Abstract

The Free Nutritious Food Program (MBG) is one of the government’s efforts to improve the nutritional quality of the population, particularly for vulnerable groups such as toddlers, pregnant women, and breastfeeding mothers. However, the process of determining aid recipients often faces challenges due to the large number of potential recipients and the variety of criteria that must be considered, which can potentially lead to subjectivity in decision-making. This study aims to compare the Analytical Hierarchy Process (AHP) and Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) methods in determining recipients of the Free Nutritious Food program in Ujung Serdang Village. The data used consisted of 100 community members assessed based on five criteria: household income, number of dependents, nutritional status, housing conditions, and other assistance previously received. The AHP method was used to determine the priority weights of the criteria, while the MOORA method was used to rank the alternatives. The results showed that the “Nutritional Status” criterion had the highest weight at 0.488, followed by “Family Income” at 0.240, “Number of Dependents” at 0.136, “Housing Conditions” at 0.090, and “Other Assistance” at 0.046. The ranking results show that alternative A085 ranked first in both methods. The AHP method identified 60 viable alternatives and 40 non-viable ones, while the MOORA method identified 39 viable alternatives and 61 non-viable ones. The research results indicate that the MOORA method is more selective and objective in determining aid recipients; therefore, it is recommended to support a more targeted distribution process for the Free Nutritious Food program.
