IMPLEMENTASI SISTEM INFORMASI GEREJA BERBASIS WEB UNTUK MENDUKUNG MANAJEMEN DAN PELAYANAN JEMAAT GKJ SEMARANG TIMUR
Full text linkThe Gereja Kristen Jawa (GKJ) Semarang Timur is located in the East Semarang area, with approximately 350 registered members, though average weekly worship attendance is only around 100 people. Member data is still recorded manually in printed books, while information on church activities, offerings, finances, inventory, and other updates is shared through WhatsApp groups or the printed Church Bulletin, which is only distributed during Sunday services. This limits access for members who are absent and makes data recording and retrieval inefficient. This study aims to design and develop a web-based information system to facilitate member data management, dissemination of worship information, and provide a platform for members to evaluate church services. The system includes features for member records (including transfers and deaths), event schedule management, evaluation forms, and regularly updated announcements. The system design follows the waterfall method, with data collected through observation, interviews, and literature review. Primary data was obtained from the GKJ Semarang Timur Church Council and administrative staff, while secondary data came from journals and books related to web-based information system development. The resulting website features a simple, user-friendly interface tailored to the church administration’s needs. The implementation of this system is expected to improve data search efficiency, expand the reach of church information, and serve as an effective communication medium between the church and its members. its congregation
PERANCANGAN SISTEM INFORMASI PERPUSTAKAAN BERBASIS WEBSITE
Full text linkThe school library functions as a learning resource center that supports the educational process and enhances students' literacy. However, in many schools, including SMP Negeri 7 Kota Sorong, library management is still conducted manually, resulting in slow services and difficulties in data recording. This study aims to design a web-based library information system to address these issues. The research method used is the Research and Development (R&D) method, which includes stages of needs analysis, system design, implementation, and testing. The results of the design show that the developed system is capable of managing book data, members, borrowing transactions, and activity reports efficiently. This system is expected to assist library staff in managing data and improving services for students

PENGUJIAN KEAMANAN DENGAN METODE PENETRATION TESTING EXECUTION STANDARD (PTES) UNTUK MENEMUKAN KERENTANAN MISCONFIGURATIONS PADA PERANGKAT JARINGAN
Full text linkThis study examines the security of the WiFi network at Universitas Pendidikan Ganesha using the Penetration Testing Execution Standard (PTES) method. The aim is to identify and analyze vulnerabilities caused by misconfigurations within the university's WiFi infrastructure. The PTES method is employed to conduct testing through phases including pre-engagement interactions, intelligence gathering, threat modeling, vulnerability analysis, exploitation, post-exploitation, and reporting. The testing results reveal several key vulnerabilities related to improper configurations, such as the use of vulnerable protocols and insecure settings. Further analysis exposes potential risks that could be exploited by unauthorized parties to access sensitive data or disrupt services. The study provides recommendations for configuration improvements and mitigation steps to enhance WiFi network security at the university. The findings are expected to serve as a foundation for developing more effective security policies and better protection for network infrastructure in academic environments.Penelitian ini mengkaji keamanan jaringan WIFI di Universitas Pendidikan Ganesha menggunakan metode Penetration Testing Execution Standard (PTES).

IDENTIFIKASI BAKTERI YANG TUMBUH PADA OLAHAN ABON IKAN CAKALANG (Katsuwonus pelamis L.) DARI UMKM KOTA BITUNG
Full text linkSkipjack Tuna (Katsuwonus pelamis L.) is a pelagic fish that dominates the waters of the Indian and Pacific Oceans. This fish has unique physical characteristics, including an aerodynamic body, a metallic blue or teal back, and transverse stripes that distinguish it from other species. In Indonesia, skipjack tuna is abundant in the waters of Manado and Maluku. This study aims to determine the types of bacteria present in processed skipjack tuna floss (abon cakalang) based on morphological and physiological characteristics through biochemical tests. This study employs a qualitative descriptive approach conducted in a laboratory setting. Data were gathered through direct observation of samples undergoing various tests and subsequently presented in a descriptive manner. Based on the identification data, 30 bacterial isolates were found in the processed skipjack tuna floss. The isolates were identified macroscopically and microscopically. The findings of the study reveal that the bacteria found in processed skipjack tuna floss, based on biochemical tests and profile matching, are suspected to belong to the Staphylococcus and Vibrio genera
SISTEM INFORMASI PENJUALAN TERINTEGRASI ANDROID: SOLUSI DIGITALISASI UMKM DALAM ERA EKONOMI DIGITAL (STUDI KASUS: KUGAR MINAMAS PANSELA)
Full text linkThis study shows how an Android-integrated sales information system can help MSMEs face challenges in the digital economy era and take advantage of growth opportunities. It also aims to improve sales efficiency in providing services to customers by designing a digitalization-based sales system with an Android model. Data collection, analysis, design, development, and testing comprise prototype method of system development. Based on the Paired Samples Test results, it is clear that H0 is rejected and H1 is accepted because the Sig value is 0.00, which means that the Sig value is less than 0.05. Based on hypothesis testing, therefore, the Sig value is less than 0.05. As demonstrated by a case study on Kugar Minamas Pansela, one of the solutions for the digitalization of MSMEs in a digital economy is the implementation of an integrated sales information system. The results of system testing show that average time before using the system is 7.42 minutes and the average time after using the system is 3.81 minutes. The results indicate that this system could be used to speed up Salt's sales and payment process with Android integration and become one of the solutions for the digitalization of MSMEs in the digital era
