Abstract

Digital transformation has become essential for improving service efficiency across various sectors, including micro, small, and medium enterprises (MSMEs) in the catering industry. Manual reservation processes often cause service delays, inaccurate data recording, and decreased customer satisfaction. This study aims to develop a web-based catering reservation system to automate bookings, streamline service management, and improve interactions between service providers and customers. The system was developed using the Agile Software Development methodology with the Scrum framework, which supports iterative, adaptive development and active user involvement. A User-Centered Design (UCD) approach was also adopted to ensure usability and alignment with user needs. The development process involved requirement analysis, system and interface design using UML, implementation with Laravel and MySQL, and evaluation through Black Box Testing and User Acceptance Testing (UAT). The system provides core features such as menu ordering, transaction management, payment confirmation, and report generation, all presented in a responsive and accessible interface. Results show that the system improves service efficiency and enhances user satisfaction, particularly in terms of system navigation, clarity of information, and ease of use. However, the study has limitations, including its application within a single MSME environment and the absence of advanced features like automated notifications or integrated digital payments. These contextual constraints limit the generalizability of findings. In conclusion, the developed system contributes to the digitalization of catering services and offers promising potential for broader application. Future research should explore scalability across various MSME types and enhance system capabilities to meet wider operational demands.

Abstract

Service teachers play a crucial role in Islamic boarding schools by imparting the knowledge and values they acquired during their studies. At Al-Kamil Islamic Boarding School, the selection of these service teachers is conducted annually to ensure only the most competent and ethically grounded candidates are chosen. Traditionally, this selection has been performed manually, which introduces several challenges, including subjectivity, inefficiency, and inconsistencies in evaluation. These limitations can compromise the fairness and transparency of the process, potentially leading to biased outcomes and reduced institutional credibility. To address these issues, this study proposes the implementation of a web-based Decision Support System (DSS) utilizing the Weighted Product (WP) method to support the teacher selection process. The WP method is particularly effective in multi-criteria decision-making, as it applies multiplicative weights to criterion scores, enabling a comprehensive and balanced evaluation of each candidate. In this application, 14 candidates are assessed based on eight criteria: morality, academic performance, craftsmanship, Quran memorization, achievements, understanding of classical Islamic texts, language skills, and computer literacy. The system calculates a preference score for each candidate using vector S and vector V normalization processes. The top three candidates identified are Arizkia Aulia (V = 0.07377), Zaskia Faliza (V = 0.07279), and Zulfa Nisa (V = 0.07231). The integration of this WP-based DSS enhances the objectivity, fairness, and efficiency of decision-making. Furthermore, it provides a replicable and scalable framework for educational institutions seeking to implement structured and data-driven staff selection processes.

Abstract

Indonesia continues to report high maternal and infant mortality rates, underscoring the urgent need for effective community-based health information systems, particularly in rural areas served by Posyandu (Integrated Health Service Posts). Despite their crucial role in primary healthcare delivery, many Posyandu still rely on manual data recording, resulting in fragmented documentation, delayed health risk detection, and inefficient decision-making processes. This study adopts a design research approach, utilizing the User-Centered Design (UCD) methodology to develop a web-based health monitoring system tailored for non-technical users, specifically Posyandu cadres in Dukuh Village, Boyolali Regency. The UCD process involved four iterative stages: understanding the user context, specifying user requirements, designing high-fidelity interface prototypes using Figma, and conducting usability evaluation through the System Usability Scale (SUS). The developed prototype includes key features such as digital patient data entry, real-time health examination input, visual health monitoring graphs, and automatic report generation by category and period. Usability testing was conducted with five Posyandu cadres who participated in defined usage scenarios and completed the SUS questionnaire. The resulting average SUS score was 84, categorized as “Excellent,” indicating that the system is intuitive, accessible, and efficient for users with limited technological experience. These findings demonstrate that the UCD approach effectively aligns system functionality with user needs, enhancing usability and supporting timely, data-driven health service decisions. This model offers significant potential for scalability and adaptation in other Posyandu settings, contributing to more integrated and responsive public health interventions at the village level.

Abstract

The rapid advancement of digital technologies has significantly impacted various sectors, including property management. However, boarding house management still relies heavily on manual processes, resulting in inefficiencies such as inaccurate tenant data, delayed payments, and difficulties in monitoring room occupancy. This study aims to design and develop a web-based room management information system for Pak Yadi Boarding House, aimed at automating and streamlining key administrative tasks. Using the Waterfall development model, the study follows five phases: requirements analysis, system design, implementation, testing, and maintenance. Data collection was performed through literature review, observation, and interviews with the boarding house owner. The system was implemented using the Laravel framework and MySQL, with system architecture designed using UML diagrams. Testing was conducted using the Black Box method, with user acceptance testing involving one administrator and ten tenants. Key features tested include room data entry, tenant registration, payment invoicing, and complaint management. Results showed that all features performed as intended, and 90% of users expressed satisfaction with the system’s functionality and interface. The system successfully reduced administrative workload, minimized data entry errors, and enhanced operational efficiency. This research demonstrates that web-based systems can improve boarding house management and offers a scalable model for similar small-scale accommodations. Future research could explore integrating mobile access and cloud storage to enhance flexibility and remote management capabilities.

Abstract

Parallax mapping is a visual rendering technique that creates the illusion of three-dimensional (3D) depth in two-dimensional (2D) game environments by shifting background layers relative to camera movement. While widely supported in advanced game engines such as Unity and Godot, its application in RPG Maker MV/MZ—a platform favored by indie developers for its accessibility—has not been adequately explored in existing game development literature. This study addresses that gap by introducing a custom five-layer parallax mapping pipeline optimized for RPG Maker’s PIXI.js-based renderer, which is not natively designed to support complex depth effects.The proposed system introduces performance-conscious features, including grouped texture loading, dynamic layer visibility (adaptive culling), and a logarithmic depth-scaling method that enhances realism without overwhelming system resources. To evaluate its effectiveness, the study adopts a sequential explanatory mixed-methods approach consisting of two phases: quantitative benchmarking across three hardware tiers (low-end, mid-range, and high-end), and qualitative feedback collection from 20 participants comprising both players and developers. Findings reveal that the system consistently achieves over 46 frames per second (FPS) on low-end devices while improving perceived depth and spatial realism by 38%. Additionally, 85% of users expressed a preference for the parallax-enhanced visuals due to increased immersion and aesthetic quality. These results demonstrate that cinematic visual depth is achievable in RPG Maker with proper optimization, offering practical guidance for developers working under technical constraints.

Abstract

Student learning achievement is a crucial element in the education sector, shaped by a variety of internal and external factors. Accurately predicting student achievement remains a significant challenge for educators and researchers, especially considering the psychological impacts of bullying. This study aims to construct a predictive model using linear regression to examine the influence of bullying levels, social support, and mental health on student achievement at SMPN 4 Pasarkemis, Tangerang Regency. A review of previous studies highlights the psychological toll bullying can have on academic performance, with many focusing on predictive models or statistical methods like linear regression to quantify these impacts. The model was developed using Python on the Google Colab platform, utilizing the pandas, statsmodels, and seaborn libraries for statistical analysis and visualization of variable relationships. Employing a quantitative, associative research design, the study involved 533 student respondents. The findings reveal that social support has the strongest positive influence on academic achievement, while higher levels of bullying and poorer mental health correlate with decreased performance. Notably, among the various forms of bullying analyzed, cyberbullying emerged as having the most significant negative impact on academic achievement. Although the model explains approximately 5.5 percent of the variation in student learning achievement, the majority of influencing factors lie beyond the scope of this analysis. The model offers potential for further development into a web-based predictive information system to assist educators in the early identification of students at academic risk.

Abstract

Extracurricular activities are an important part of the holistic development of students which includes the formation of character, interests, talents, and social skills. However, many educational institutions still manage these activities manually through spreadsheets and printed documents, resulting in data duplication, information delays, and low transparency. This research aims to design and develop a web-based extracurricular information system to support the administration, monitoring, and evaluation of activities in an efficient and structured manner. The development of the system uses the Waterfall model chosen for its sequential and well-documented workflow, suitable for systems with predefined needs from the outset. The development stages include needs analysis, system design using UML, implementation with Laravel 9 and MySQL, as well as testing through the Black Box method and direct evaluation by the end user. The results of the Black Box test show that all system features are working according to specifications. Additionally, feedback from users shows a high level of satisfaction with the ease of use, navigation, and relevance of the features provided. This system successfully overcomes administrative challenges in managing extracurricular activities and is able to improve operational efficiency and user engagement. With the support of features such as automatic periodic assessments, PDF reports, notifications to parents, as well as a multilingual interface, the system has the potential to be more widely adopted by educational institutions that have similar contexts.

Abstract

Accurate and efficient data transmission is increasingly essential due to the growing reliance on digital communication, particularly for multimedia content such as images. Orthogonal Frequency Division Multiplexing (OFDM) provides high bandwidth efficiency and strong noise resilience by transmitting data over multiple orthogonal subcarriers. Despite its advantages, limited studies have explored how modulation schemes influence frequency-domain characteristics during image transmission under different noise conditions. This study addresses that gap by evaluating digital image transmission through OFDM using Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK) modulation. The objective is to compare spectral performance across various signal-to-noise ratio (SNR) levels. A grayscale image is converted into a binary stream, modulated using BPSK and QPSK, and processed through an OFDM system with 512 subcarriers and a 25% cyclic prefix. The signals are transmitted through an Additive White Gaussian Noise (AWGN) channel at SNR values of 0 dB, 5 dB, and 10 dB. Power Spectral Density (PSD) is measured using the Welch method with a Hamming window, 50% overlap, and 1024-point Fast Fourier Transform (FFT). The results show that increasing SNR improves spectral sharpness, reduces the noise floor, and enhances symmetry. BPSK offers better performance in noisy conditions, while QPSK is more efficient in high-SNR environments. These findings provide practical insight for optimizing modulation choices in OFDM-based image transmission systems where spectral efficiency and noise robustness must be balanced.

Abstract

The furniture industry often struggles with setting accurate selling prices due to the lack of structured and precise cost calculation systems. Many furniture entrepreneurs still rely on traditional methods that base prices on market trends, without accounting for underlying production costs. This often leads to prices that are too low, eroding profit margins, or too high, making it difficult to stay competitive. This study introduces a novel Cost of Goods Manufactured (COGM) calculation system, integrated with the Bill of Materials (BOM) method, to advance current pricing systems in the furniture industry. By incorporating key cost elements such as raw materials, labor, and the impact of waste and rework, the system enhances the accuracy of COGM calculations. Additionally, it offers greater transparency by providing a detailed breakdown of each cost component, allowing entrepreneurs to better understand their production expenses. The implementation of this system led to a 15% improvement in pricing accuracy, significantly reducing pricing errors and optimizing production costs. Furthermore, businesses reported a 20% increase in competitiveness due to more informed pricing strategies. This research demonstrates that integrating COGM with BOM not only improves production efficiency but also strengthens pricing strategies, contributing to long-term profitability. It highlights the role of cost transparency in driving sustainable growth, particularly for small and medium-sized furniture enterprises.

Abstract

This study aims to design and implement a website-based ordering and management system specifically for water apple commodities in Betokan Village, Demak. Farmers in this area previously relied on manual stock and transaction recording, which led to frequent issues such as data inaccuracy, difficulties in inventory tracking, and inefficiencies in sales operations. To address these challenges, a digital system was developed using the Waterfall method, comprising five stages: requirements analysis, system design, implementation, testing, and maintenance. The platform was built using the PHP programming language with the Laravel framework and a MySQL database. The system includes key features such as real-time stock updates, online ordering, transaction recording, and automated report generation. Evaluation of the system was conducted using black-box testing on eight core functions, of which 87.5% passed as expected. Post-implementation results showed a 60% reduction in inventory-related errors and a notable decrease in administrative workload. The system was also piloted with a sample group of local users, and feedback indicated increased efficiency in stock monitoring and transaction processing. This research contributes significantly to the digital transformation of local agricultural communities by offering a practical, scalable solution that improves business operations and customer service. Moreover, it enhances the ability of rural farmers to enter the digital market ecosystem and expand their market reach. The system demonstrates how localized digital tools can bridge gaps in rural agribusiness, increase productivity, and promote economic resilience through technology adoption.
