Abstract

Learning media is an important factor in the learning process. By using the right learning media, someone can easily understand what is being studied. Currently, augmented reality is a technology that is being developed in various fields, one of which is in the field of education. Augmented reality can be an alternative to effective and interactive learning media because augmented reality can combine 2D or 3D objects into a real environment. To learn about the internet of things devices, currently, students can only learn through books or do the hands-on practice. If an error occurs during practice, it can cause damage to the internet of things device. By utilizing augmented reality technology, a new learning media is created by combining 3D objects from internet of things devices into the real environment. This learning media application was tested using the Blackbox and Mean Opinion Score methods. Blackbox testing shows that all functions have been running properly by the functional requirements that have been defined. Testing using the Mean Opinion Score shows that the average student respondent's assessment of the application is stated to strongly agree as much as 60.3% and agree as much as 35.3%.

Abstract

In an organization, the development of a system cannot be done as a whole but is done in stages, This is caused by organizational needs that are always changing from time to time. Also, in an organization, there is a lot of data or information that is done together, where one data can be used by several fields and one data can also be used for many functions. Similar to SMK 1 Selong, the same data or information can be used by several midwives and can be used for many functions. To overcome these problems in this study carried out the design and construction of Service Oriented Architecture (SOA). SOA is software development with a service approach. In SOA the data needed for the development of a system is defined from the start to facilitate the development of a continuous system and can facilitate if there is a change in data because SOA provides the ease of integration of several different systems. In this research the SOA analysis and design process at SMK 1 Selong has been carried out and 9 services are obtained: student service, employee service, service teacher, service value, financial service, curriculum service, library service, service facilities and infrastructure, and service administrator. These services are implemented using web service technology with a codeigniter framework

Abstract

The Business processes of SMP Negri 10 Mataram keep changing due to the organization’s necessity, so the development of existing systems and applications is needed. For the complex cases, they need to integrate the systems and applications to deliver the effective and good quality of educational processes and activities. SMP Negeri 10 Mataram has several problems: until these time in every administrative section do their processes business or their task manually, that is not efficient especially in term of time for work, and more there are no relatable things between every section. By this research to resolve these problems, the administrative management system integration was developed by using the Service Oriented Architecture (SOA) method. Service-Oriented Architecture (SOA) is one of many ways to design data integration from several different systems. Service-Oriented Architecture (SOA) is a software development technology architecture with a service approach, allowing the relationship and exchange of data or information between every systems and application to be much easier. In this research, the SOA analysis and design process was conducted at SMP Negeri 10 Mataram and obtained six services, namely: service administrator, financial service, staffing service, student service, infrastructure services, library service.

Abstract

PT. Hidayat Energi Putratama is a 3 kilograms elpiji gas distribution agent that distributes elpiji gas to the base which then forms the base and will distribute to the retailer. Currently the calculation of distribution costs at PT. Hidayat Energi Putratama has not implemented an information system that can manage the calculation of distribution costs and the costs incurred are not optimal, so a system is needed to calculate distribution costs. The purpose of this research is to design an information system optimization of the distribution of 3 kilograms elpiji gas at PT. Hidayat Energi Putratama uses the least cost method that can perform calculations to help companies find out where the 3 kilograms elpiji gas should be distributed so that the costs incurred are kept to a minimum. From the results of research and calculations using the least cost method, the results obtained that the cost generated by the system is Rp. 1,120,600 less than the original cost incurred by the company of Rp. 1,500,000 so it can be said that the cost generated by using the least cost method is optimal. System testing is done by black box testing, theoretical calculations, and Mean Opinion Score (MOS) testing. The results of black box testing and theoretical calculations show that the system is running well and correctly. In the MOS test conducted on 30 respondents, the average result was 4.28 on a scale of 1 to 5. These results indicate that users are satisfied with the system built.

Abstract

The Government Office and Regional Development Agency (OTDA) have the main task of implementing regional autonomy by preparing the Regional Government Administration Report (LPPD). The preparation of LPPD for the NTB Province is still done manually, including the collection of data for each government affair and the calculation of government performance achievements found in various indicators, resulting in a lengthy data collection process for reporting. With the advancement of information technology, a solution can be provided to address the aforementioned issues by developing a web-based Local Government Administration Reporting Information System (SIPPDA) using the extreme programming development method. The system development is carried out using the Laravel framework. During the testing phase, unit testing is performed to verify the functionality of the system, and the results indicate that it runs smoothly without errors. User Acceptance Testing (UAT) is then conducted in three iterations with different numbers of respondents. In the first iteration, with 5 respondents, the acceptance rate is 73.71%. In the second iteration, with 8 respondents, the rate is 89.86%, and in the third iteration, with 5 respondents, the rate is 79.5%.

Abstract

The development of a web-based Scout Information System for Kwartir Cabang Mataram aims to improve the management of member data and activities through a REST API. The current data management process, relying on tools like Google Forms and Microsoft Excel, is inefficient and error-prone. To address these issues, the proposed system integrates all levels of scout organization within the Mataram City, from school-based scout units (gugus depan) to the city level scout organization (kwartir cabang), creating a centralized platform for real-time data access. Built using the Scrum method, the system is developed through iterative sprints and regularly improved based on stakeholder feedback. The REST API architecture enables seamless communication between the back-end and front-end components, ensuring system scalability, flexibility, and future integration with other platforms, including mobile applications. Black-box testing guarantees the functionality of the system’s endpoints. This system is expected to enhance operational efficiency and reduce administrative delays.

Abstract

Education is a crucial component in a country's development, and the quality of education is a key factor in determining national progress. In Indonesia, the Ministry of Education, Culture, Research, and Technology has implemented the Merdeka Curriculum, which provides students with greater flexibility to choose subjects based on their interests and talents. At SMAN 4 Mataram, the subject selection process starting in the second semester of grade 10 still faces challenges, such as students' difficulty in determining suitable majors and the lack of an integrated data management system. This study developed a decision support system based on the Profile Matching method to provide objective major recommendations by aligning students’ competencies with the criteria of each major. The system was developed using the Waterfall model to ensure a structured design process. Testing was carried out with White Box Testing to validate algorithm calculations, Black Box Testing to check system functionality, and User Acceptance Testing to assess user satisfaction. The results showed a very positive response from administrators (MOS 4.95 out of 5.00) and a positive response from students (MOS 4.00 out of 5.00). This research contributes a practical and flexible decision support solution specifically adapted to high schools implementing the Merdeka Curriculum. With this system, the major selection process is expected to become more efficient, integrated, and capable of providing recommendations that better align with students’ interests, talents, and academic potential. Key words: Education, Decision Support System (DSS), Majoring, Profile Matching, Waterfall.

Abstract

Mataram City's scouting administration information system currently relies on manual processing like Google Forms and Excel that encounter challenges at the Scout Unit level up to the District Council. These manual processing result in data mistakes, reporting delays, and challenges for the Regency Council to obtain real-time information. This project aims to create a website-based information system using the Scrum methodology in order to centrally digitalize members, scoutmasters, and scout activities data management. Using Next.js and TypeScript, the authors develop a front-end and data retrieval from API Endpoints. This application to enhance user productivity, facilitate cross-level reporting, and provide effective data visualization. These benefits are supported by the User Acceptance Testing results, which show an average feasibility score of 81.74% in the "good" category across functionality, reliability, usability, and efficiency aspects. This confirms that the digitalization of scout administration is both ready to be implemented and aligned with user expectations.
