Abstract

The housing unit reservation system is still manual, with prospective buyers making reservations directly at the location offline, which often causes inefficiency, recording errors, and delays in information to prospective buyers. Therefore, this study aims to develop a Laravel and Livewire-based Housing Reservation Management System with a WhatsApp Gateway for Bumi Coprayan Indah Housing. This system is designed to enable prospective buyers to make housing unit reservations online, manage reservation data more efficiently, and receive automatic notifications via WhatsApp. The research method used is the Waterfall-based software development method, with the Laravel 10 framework, and the stages are requirements analysis, system design, implementation, and testing using the Black-Box Testing method and User Acceptance Testing (UAT). The test results indicate that the developed system functions well according to the predefined specifications. Based on these results, user satisfaction ranges from 76% to 80.4%, with the highest score for the house search feature (80.4%) and the lowest for the efficiency of the booking process (76%). This indicates that the system has been well accepted by users. The implementation of this system has a positive impact on reservation efficiency, reduces recording errors, and facilitates communication between property developers and prospective buyers. This system is expected to be an innovative solution for digitizing the housing reservation process in a more modern and structured manner.

Abstract: Rapid technological developments have had a significant impact on various sectors, including education, where Human Computer Interaction (HCI) plays a role in increasing the effectiveness of technology-based learning. However, there are still challenges in the implementation of HCI, such as interface design, infrastructure, and user engagement. This study aims to evaluate the application of HCI in education by reviewing technologies such as chatbots, e-learning, Augmented Reality (AR), Virtual Reality (VR), Artificial Intelligence (AI), and the use of PowerPoint to support learning. Using the Systematic Literature Review (SLR) method based on journals published in 2020-2024 from Google Scholar, the results of the study show that chatbots increase communication efficiency and access to information, while AR and VR-based learning media help understand concepts, especially for students with special needs. The e-learning system designed with HCI principles provides an interactive and user-friendly learning experience, although there are still obstacles such as limited infrastructure and lack of training for educators. In addition, the use of AI in learning media has great potential in increasing engagement and quality of learning. Therefore, this study emphasizes the importance of user-oriented interface design, strengthening technological infrastructure, and collaboration between stakeholders to support more optimal implementation of IMK in the world of education.Keyword: human and computer interaction (HCI); artificial intelligence (AI); augmented reality (AR); education. Abstrak: Perkembangan teknologi yang pesat telah memberikan dampak signifikan di berbagai sektor, termasuk pendidikan, di mana Interaksi Manusia dan Komputer (IMK) berperan dalam meningkatkan efektivitas pembelajaran berbasis teknologi.

Abstract

Kendal Regency has significant potential in community forest plantations, which contribute to the regional economy. However, the mapping of leading commodities based on productivity has not been conducted optimally. This study aims to map leading community forest plantation commodities using the K-Means Clustering algorithm. The novelty of this study lies in the application of the K-Means Clustering algorithm by integrating land area and production volume as the basis for mapping leading commodities at the regency level. Secondary data from the Central Bureau of Statistics of Kendal Regency for the 2019–2023 period, covering seven community forest plantation commodities, were used. The research stages included data preprocessing using Min-Max normalization, clustering into three clusters using the K-Means algorithm, and cluster evaluation employing the Within-Cluster Sum of Squares (WCSS). The results show that the K-Means algorithm successfully grouped the commodities into three clusters based on their productivity characteristics. Sugarcane formed a distinct cluster as the leading commodity due to its highest productivity despite its relatively small cultivation area. These findings provide data-driven insights to support decision-making for the development of community forest plantations in Kendal Regency

Abstract

Prepaid internet bills at Pulsaku Cell were still recorded manually, and customers were often notified late. To address this, the study built TAPENDIT, a web application that accepts payments through the Midtrans payment gateway. The application was developed with PHP and the Laravel framework, stores its data in MySQL, and sends bill notifications by email automatically. Development followed the Waterfall model, with system requirements gathered through direct observation of the manual billing process, interviews with the business owner, and questionnaires. A User Acceptance Test (UAT) involving 50 of 128 customers produced an average score of 78.1%, with the highest score for the email notification feature (83.6%). These findings indicate that TAPENDIT is acceptable to customers and has the potential to speed up payments and reduce the administrative recording workload.
