Abstract

Indonesia is currently facing a food crisis exacerbated by climate change, which disrupts agricultural patterns and causes crop failures. These disruptions lead to increased food prices and reduced purchasing power, particularly affecting the lower-income population. One sustainable solution is home gardening, which can enhance food availability and reduce household expenses. However, not everyone has the knowledge or resources to start gardening. To address this gap, the PANENKU application was developed as a mobile-based platform aimed at educating users on how to grow essential food crops such as chilies, shallots, and ginger. PANENKU integrates interactive learning through simulation games that guide users step-by-step, from planting to harvesting. The application leverages the Waterfall development model for systematic design and includes features such as AR (Augmented Reality) experiences, informative articles, and a community forum. These elements foster engagement, support peer-to-peer learning, and enhance users gardening knowledge. By incorporating educational gameplay and expert interaction, PANENKU not only supports individual self-sufficiency but also promotes environmental sustainability and strengthens local economies. System testing using black box testing which tests four features shows that the features can run well and the System Usability Scale (SUS) shows a result of 86%. The results of this test show that the app is particularly beneficial for housewives and beginner gardeners, offering an innovative and accessible approach to addressing food security challenges in Indonesia. Ultimately, PANENKU aspires to be a positive, inclusive platform for agricultural education and community empowerment.

Abstract

The selection of a boarding house is an important decision that cannot be made arbitrarily because a boarding house is a place to rest after a day of activities outside, whether for work or studying. The border area differs slightly from other areas, adding complexity to the list of considerations in searching for a boarding house. To address the varying preferences, a Decision Support System (DSS) can be utilized, assisting individuals in making better decisions when selecting a boarding house. A DSS is designed to help decision-makers analyze and compare various alternatives based on predetermined criteria. This research was conducted to analyze the effectiveness of the SMART method and the SAW method commonly used in DSS in providing recommendations for the best boarding house according to user preferences. The results showed that both the SMART method and the SAW method produced similar and consistent results, with both placing "Kost & Kontrakan Senange" as the most recommended boarding house among the five boarding houses in the border area, with a final score using the SMART method of 0.775 and a preference value from the SAW method of 0.983.

Abstract

Urban disparities in maternal and child health remain a critical challenge in achieving the Sustainable Development Goals (SDGs). This study aims to map the disparity of health risks among infants and toddlers across 44 subdistricts in DKI Jakarta by analyzing three key indicators: prevalence of low birth weight (LBW), infant mortality, and undernutrition. Cross-sectional data from 2024 (n=176) were normalized using Min-Max scaling to minimize scale bias. The clustering process using the K-Means algorithm was conducted after determining the optimal number of clusters (k=5) through the Elbow method. Cluster validation employed three metrics—Silhouette Score (0.65), Davies-Bouldin Index (0.45), and Calinski-Harabasz Index (82.2)—demonstrating the model's consistency. Stability analysis through subsampling further confirmed the reliability of the results (standard deviation <0.1). Five risk patterns were identified: (1) two low-risk clusters (LBW <1.0%; undernutrition <2%), (2) two moderate-risk clusters (LBW 1.0–1.75%; infant mortality 0.5–3%), and (3) one high-risk cluster (LBW >1.75%; undernutrition >8%). The subdistricts of Jagakarsa and Kepulauan Seribu were identified as priority intervention hotspots due to high comorbidity risks. The findings indicate that the K-Means approach is effective in supporting evidence-based resource allocation policies, particularly in optimizing NICU services and nutrition supplementation programs in high-risk areas. This spatially based approach also facilitates more intuitive visualization for targeted and efficient planning of local health programs.

Abstract

Choosing the right raw material supplier is a crucial factor in maintaining quality and production continuity in the food industry. This study proposes a hybrid approach that combines the Respond to Criteria Weighting (RECA) method to objectively determine the weight of the criteria and the Utilities Theory Additives (UTA) method to evaluate alternatives based on partial utility functions. This approach is designed to accommodate the complexity of decision-maker preferences as well as the multi-criteria assessment dynamics that often occur in the supplier selection process. Case studies were conducted on several supplier alternatives by considering various criteria. The results of the ranking of alternative suppliers based on the combination of the RECA and UTA methods can be seen that the MB alternative obtained the highest score of 0.8578 as the first rank, followed in order by TM obtained a score of 0.8576 as the second rank, and AJ obtained a score of 0.8573 as the third rank. The results of the analysis show that the combination of the two methods is able to produce accurate, consistent, and relevant ratings to the strategic needs of the company. This approach makes a significant contribution to improving objectivity, transparency, and efficiency in decision-making, particularly in the food industry sector which relies heavily on supply chain reliability.

Abstract

The election of the Head of the Finance Division is an important decision that requires an objective and systematic evaluation of the existing candidates. This study proposes the application of a combination of Entropy and SMART (Simple Multi-Attribute Rating Technique) methods to support the decision-making process in the election of the Head of the Finance Division. The Entropy method is used to objectively determine the weight of the criteria, based on the distribution of candidate assessment data, while the SMART method is applied to assess each candidate based on predetermined criteria. The results of the ranking of candidates for the Head of the Finance Division are based on the final score obtained by each candidate. Based on these results, candidate A5: Eko Prabowo ranks highest with a score of 0.6667, followed by A7: Gita Susanti with a score of 0.6097. These results show that Eko Prabowo is the most superior candidate to be considered as the Head of the Finance Division, based on the assessment method used in this study. The combination of these two methods allows for more accurate, transparent and accountable decision-making, as it is based on objective and structured calculations.

Abstract

Providing vehicle loans is one of the important services in the financing sector that requires an objective and accurate evaluation process of prospective debtors. This research aims to develop a Decision Support System (SPK) that can assist in the selection process of providing vehicle credit by combining the G2M Weighting and Comprehensive Distance-Based Ranking methods. The G2M method is used to objectively determine the weight of criteria based on multi-assessment analysis, while the CDR method is used to conduct alternative rankings based on a comprehensive distance to ideal and non-ideal solutions. The results of the calculation using the comprehensive distance-based ranking method, Gita ranked first with a final value of -0.0098, showing that it has the closest distance to ideal conditions and the furthest from non-ideal conditions compared to other alternatives. In second place is Ahmad with a value of -0.0067, followed by Hadi in third place with a value of -0.0042. The final results show that the combination of these two methods is able to provide effective recommendations in identifying potential debtors who are most deserving of credit, taking into account all assessment criteria in a comprehensive and structured manner. This system is expected to improve decision-making accuracy, speed up the selection process, and minimize the risk of errors in vehicle lending.

Abstract

This study examines people's reactions to the Indonesian government's plan to adjust the VAT rate from 11% to 12%, which is scheduled to take effect in 2025. This policy triggered a variety of opinions among netizens, especially on the social networking service X. To explore public opinion, data was collected through web crawling techniques from October to December 2024, resulting in 1,871 records. Then the dataset was preprocessed by text cleaning, case folding, tokenization, stopword removal, and stemming, and the dataset was reduced to 1806. In addition, up to 1000 data will be manually labeled, negative, neutral, positive, by language experts to ensure that each sentence has the appropriate label. These data are used for testing and training, then up to 806 unlabeled data are used as final testing. At the word weighting stage, the Term Frequency-Inverse Document Frequency (TF-IDF) method is used to perform the process. In this study, three machine learning algorithms were used to compare the classification performance, namely Support Vector Machine (SVM), Random Forest, and Decision Tree. Based on the evaluation results, the SVM algorithm recorded the highest accuracy rate of 94%, followed by Random Forest with 93% and Decision Tree with 91%. The results showed a predominance of negative sentiments, indicating public dissatisfaction with the policy. This study proves that machine learning techniques can be effectively used to capture public perceptions through social media, which in turn can be a benchmark for the government to make decisions that will be enforced.

Abstract

The mentoring program at the University of Muhammadiyah Purwokerto (UMP) organized by the Institute for the Study and Practice of Islam (LPPI) was first implemented in the 2004/2005 academic year. This program aims to provide guidance in understanding and internalizing the values of Al Islam and Muhammadiyah (AIK) in daily life. However, until now, it  still uses a manual system in recording attendance, managing materials, and monitoring mentoring activities. This causes several problems, such as lack of efficiency in administration, difficulties in data reporting, and limited access for mentors and mentees. Therefore, a website-based information system is needed  to optimize mentoring management. This research aims to design a website-based application  that simplifies the mentoring administration process, improves the efficiency of attendance recording, and provides easier access for mentors, mentees, coaches, and  LPPI admins. The method used in the development of this system is prototyping, which consists of several stages, including gathering needs, making  initial prototyping, evaluation by users, and developing the system based on the feedback received. This system is built using website-based technology  using the PHP programming language  with the Laravel framework, MySQL is used as a database, for the interface display, Tailwind CSS is used. The results of the study show that this mentoring system can improve the efficiency of mentoring administration with an online attendance process, activity reporting in the form of a mentor logbook and activity evaluation. In addition, this system allows  LPPI admins to monitor the course of mentoring in real time, so that transparency in mentoring activities increases. The test with black-box testing stated that all the main functions could run well according to their functions, then for the test with SUS (System Usability Scale) it showed that the average value of the SUS test was 84.16 and was stated as very good. It is hoped that the mentoring process at UMP can run more effectively, efficiently, and structured.
