Promotion and provision of information on subsidized housing for low-income communities (MBR) is still carried out conventionally, such as throught brochures, banners or exhibitions. This method is considered less effective in reaching the wider community, especially the younger generation who are more familiar with digital technology. This research aims to design and create a web-based information system for sales promotion of subsidized housing at Mutiara Gerden Housing. This system is expected to increase the attractiveness and trust of potential buyers towards the products offered, as well as help developers in conveying information more quickly, widely and interactively. This research uses the waterfall method which includes problem identification, problem analysis, goal determination, literature study, data collection (observation, interviews, dan document study), system design including problem analysis, design, coding, and testing. System implementation is carried out after the design is completed, followed by testing using the black box method to ensure functionality and error handing. The programming lannguages used are HTML and PHP for web services, and MySQL as the database. System design also utilized the Unified Modeling Language (UML) with diagrams such as use case diagrams, and activity diagrams. The result of thir research is a web-based subsidized housing sales, promotion information system application thet helps promote houses in Mutiara Garden Housing. This application includes a login page for accesing the system, a product deatil page for complete information, a product booking page for unit reservations, and a home menu for a product overview. This system is expected to make it easir for employees to promote homes more effectively and efficiently.

This community service program was implemented to overcome the limited technical capacity of teachers and students at SMK Negeri Jambu in mastering the installation and programming of battery-based electric vehicles, which is a crucial skill in preparing competent human resources for the rapidly evolving green vehicle industry. The program specifically aimed to enhance participants’ knowledge and skills in several key areas, including the installation of electric motor control systems, management of battery energy, and maintenance of essential electric vehicle components. To achieve these goals, the activities were carried out using a blended method that integrated lectures, demonstrations, and direct hands-on practice, supported by continuous mentoring and systematic evaluation. In addition, QR Code–based learning resources were incorporated to provide participants with quick and efficient access to digital instructional materials, allowing for more flexible and independent learning. The evaluation results revealed significant progress in both the theoretical understanding and practical abilities of the participants. They were able to demonstrate improvements not only in operating and maintaining electric vehicle systems but also in identifying problems and performing troubleshooting independently. These findings suggest that the program effectively contributed to building sustainable competencies for teachers and students, equipping them with relevant skills aligned with the needs of the green automotive industry, while also promoting technological adaptation and innovation in vocational education.

The development of information technology in the Industrial Revolution 4.0 era requires the younger generation to possess digital literacy skills, one of which is computer programming. Programming is not only a technical skill but also helps in developing logical, systematic, and creative thinking. This study aims to describe the implementation and results of Java-based basic programming literacy training for 30 SMA 3 students. The students were selected based on their interests and recommendations from teachers. The training was held in a computer laboratory, utilizing a learning-by-doing approach with methods that included material delivery, demonstrations, and hands-on practice. Evaluation was conducted through both theory tests and simple programming tasks. The results indicated an average 30% increase in understanding of structured programming concepts compared to before the training. Additionally, 85% of the students were able to successfully complete tasks involving the creation of simple programs using variables, operators, branching, and loops. Beyond the technical skills, the training also had a positive impact on non-technical skills such as self-confidence, teamwork, and critical thinking. In conclusion, this training program successfully met its goal of enhancing students’ basic programming literacy and can serve as a practical learning model that aligns with the needs of the digital era, encouraging active participation in the digital world.

Training in creating animated characters using the Scratch application serves as an introduction to block-based programming fundamentals that are simple, easy to operate, interactive, and engaging. This training offers promising competency outcomes, as students can further develop their skills through animated stories, games, or presentations. Since 2018, the Ministry of Education and Culture has promoted the integration of informatics education into the 2013 curriculum, including computational thinking skills, which are essential for both current and future generations. The partner for this community service training activity is the students of MTs Pembangunan Nurul Islam, located in Sarimulya, Setu, South Tangerang. This initiative is a tangible step toward implementing informatics learning through the introduction of block-based programming fundamentals. The training involved stages of introduction, instruction, and guidance in using the application. Based on observations and discussions with the partner school, several issues were identified in learning Information and Communication Technology (ICT). One of the causes is students’ lack of awareness of the importance of learning programming fundamentals, coupled with the stigma that programming is difficult, uninteresting, and boring. To address both technical and management issues, the proposed solutions in this community service program include: first, facilitating and providing guidance on the use of the Scratch application for MTs students, with the hope that they will understand basic programming without fear or difficulty. Second, offering engaging, interactive, simple, and easy-to-understand lessons on basic programming using Scratch, by providing example projects such as creating animated characters. The training program was implemented smoothly, and all participating students enthusiastically followed each stage of the training. Their motivation was encouraged to become familiar with programming, increasing their interest, understanding, and confidence in basic programming skills. The ultimate goal is to foster students' interest, knowledge, and skills while boosting their self-confidence in ICT learning, particularly in basic programming.

This study aims to analyze the Public Relations (PR) communication strategy used by PT Gamelan Tour in building the company's positive image. This research applies the Two-Way Symmetric Communication theory developed by James E. Grunig and Todd Hunt, which emphasizes the importance of reciprocal communication between the company and the public. Through this approach, PT Gamelan Tour aims to listen to customer complaints, provide clear explanations,and resolve issues in a transparent and effective manner. Additionally, this study discusses various relevant communicationmanagementmodels,including thetwo-way symmetric model, which helps the company maintain mutually beneficial relationships with its customers. The research methodology uses a qualitative approach, collecting data through in-depth interviews with key stakeholders at PT Gamelan Tour, including Vania Nefrela Regar (Public Relations), Reva Agustina (Ticketing &Hotel), and the company's customers. This study adopts four steps of Public Relations strategy, which include: (1) defining the problem/facts to identify existing issues, (2) planning and programming to formulate effective communication strategies, (3) taking action and communicating to implement the planned strategies, and (4) evaluating the program to assess the success of its implementation and its impact on the company's image. The research findingsindicate that effective communication strategies, whether in the form of feedback, direct communication, or mutual understanding, can improve the company's image and strengthen relationships with customers.This studyalsohighlightstheimportanceofthoroughcommunication planning and consistent implementation to achieve the company's goals in building positive relationships with the public.

Production planning is one of the most important factors in improving business continuity. The preparation of production planning is related to the optimization of production for a particular business so that the business can operate efficiently and production activities achieve competitive prices. The preparation of production planning must consider several factors because every business has different goals that it wants to achieve. The Goal Programming method aims to minimize deviations from the targets set by the business, so that business goals can be achieved optimally. This research aims to optimize production in a company that can accomplish more than one goal.  The method used in this study is Systematic Literature Review (SLR), and this study identifies 5 previous journals. The source of information used in this study is articles from national journals published between 2018-2024. The results of this study show that Goal Programming is a very effective tool in production and distribution planning in various industrial sectors.
