Abstract

Water security has become an increasingly critical issue in rapidly growing urban regions such as Medan City, where population expansion, uneven infrastructure development, and localized contamination events continue to threaten the availability and quality of safe water. This study evaluates the effectiveness of three eco-friendly water treatment technologies—Bio Sand Filter (BSF), biochar-based filtration, and Constructed Wetland micro-systems (CW-micro)—as sustainable solutions for strengthening water security across household and community scales. Field testing, laboratory analysis, and Multi-Criteria Analysis (MCA) were employed to assess each technology's performance using microbiological, physicochemical, economic, and environmental indicators. Results show that the BSF achieved the highest MCA score (0.86), demonstrating superior microbial removal efficiency (up to 97%) and economic suitability for low-income households due to its low-cost materials and simple operation. The biochar filtration system recorded a score of 0.79 and demonstrated strong removal of metal contaminants, particularly Fe and Mn, making it well-suited for areas affected by industrial pollution or groundwater quality degradation. The CW-micro system achieved a score of 0.74 and performed effectively in reducing BOD and TSS, highlighting its potential for community-scale treatment and integration with urban green infrastructure. Overall, the findings indicate that nature-based filtration technologies offer a practical and sustainable pathway to improving Medan City's water quality while promoting environmental resilience, lowering treatment costs, and enhancing community self-reliance. The study concludes that these eco-friendly technologies should be incorporated into local water management strategies, supported by Perumda Tirtanadi policies, and monitored through long-term spatial water quality assessments to achieve a more water-secure and sustainable urban future

Abstract

This research aims to analyze the learning performance of vocational high school students in Informatics subjects thru the integration of Generative AI (Gemini) with the K-Means Clustering algorithm, an approach that is still rarely applied in the Indonesian educational context. The research data includes 28 students, consisting of 8 males and 20 females, whose performance was analyzed based on assignment, quiz, and exam scores. The clustering results yielded three main performance groups: high, medium, and low clusters. Gemini integration helps accelerate the process of interpreting the clustering results and provides a deeper understanding of students' learning patterns. The research findings indicate that the combination of generative AI and cluster analysis can generate more accurate insights to support the implementation of adaptive learning and data-driven decision-making by teachers. Additionally, this study contributes to the development of learning analytics at the vocational education level, while also opening opportunities to implement more personalized learning strategies. Further research could expand the data scope, test other clustering algorithms, and develop an analytics dashboard to facilitate data utilization by educational institutions.

Abstract

The website of the Faculty of Computational Science and Digital Intelligence (FASANDI) at University of Pembangunan Panca Budi serves as a medium of information about the faculty profile, academics, tuition fees, facilities, and registration procedures. In order for this information to be easily accessible and understandable to users, a user experience (UX) evaluation needs to be conducted. The objective is to analyze the UX on the FASANDI UNPAB website using the Cognitive Walkthrough method with reference to usability principles. This method is used to assess how users, especially new users such as prospective students, complete key tasks on the website without external assistance. The evaluation was carried out by compiling task scenarios such as searching for study program information, viewing faculty profiles, and understanding the registration procedures linked to external portals. The analysis results show that the website has a fairly complete information structure, but several obstacles were found, such as suboptimal navigation consistency, poorly organized menu placement, and a lack of contextual clues to help users understand the flow of information access. In addition, several pages require visual rearrangement so that important elements are more easily visible.

Abstract

Macrame craft microbusiness is one of the creative economic sectors that has high potential in increasing community income. However, limited production resources such as the number of threads, working time, and availability of accessories often cause business actors to experience difficulties in determining the right production composition to obtain maximum profits. This study aims to analyze and formulate a Linear Programming model as a decision-making tool in maximizing the profits of macrame craft microbusinesses. The research method used is a quantitative approach by identifying decision variables, objective functions, and production constraints based on data on raw material capacity, processing duration, and profits for each type of product. The mathematical model solution is carried out using the Simplex method to obtain the optimal combination of product quantities. The results show that Type 1: Macrame Keychain is produced in a total of 40 Units, Type 2: Macrame Small Wall Hanging is produced in a total of 30 Units and Type 3: Macrame Plant Hanger is not produced. The goal of minimizing the total thread encourages production as much as possible from the product with the smallest (Type 1), up to the production/demand limit . After is met, take the product with the next smallest (Type 2). Since other constraints (nodes, clock, S) do not preclude this choice in this example, the greedy solution is optimal.

Abstract

Accurate door status detection and notification are essential for guaranteeing passenger safety and mitigating operational risks. Traditional car indicators, such as dashboard lights and basic whistles, offer little contextual information and frequently do not specify which door is ajar. Such constraints diminish the user's situational awareness, particularly when the driver is external to the car or in a cacophonous setting. This study presents an economical, embedded audio notification system for multiple doors, utilizing five normally closed push-button switches, an Arduino Uno microcontroller, a DFPlayer Mini MP3 playback module, an audio amplifier, and an 8-ohm speaker to deliver distinct voice notifications. MP3 messages in the Indonesian language are assigned to each door, facilitating unambiguous and contextually relevant feedback. The experimental findings demonstrate complete detection accuracy across 200 activation cycles. The device exhibits exceptional dependability, minimal power consumption, and straightforward integration, making it suitable for safety upgrades in aftermarket automobiles
