Abstract

Perusahaan baterai di Jakarta memproduksi baterai tipe AAA berbahan alkali pada lini perakitan, namun menghadapi tantangan tingkat cacat sebesar 6,9% dari total produksi 5.649.270 unit pada Januari hingga April 2025, melebihi batas maksimal 5%. Penelitian ini bertujuan mengidentifikasi penyebab cacat dan mengusulkan perbaikan menggunakan metode DMAIC Six Sigma. Data dikumpulkan melalui wawancara dan observasi, dianalisis dengan diagram sebab-akibat, FMEA, dan 5W+1H. Hasil menunjukkan DPMO sebesar 23.093 (tingkat sigma 3,49), dengan cacat dominan Low Voltage (4,17%). Penyebab utama meliputi kurangnya perawatan mesin, kelelahan operator, dan kualitas material rendah. Usulan perbaikan meliputi perawatan mesin rutin mingguan, pelatihan operator, dan pemeriksaan material. Implementasi usulan ini menurunkan tingkat cacat di bawah 5%, meningkatkan kualitas produk.

Abstract

Attendance recording is a crucial administrative activity in educational institutions because it is directly linked to discipline, reporting, and decision-making at the school level. However, manual attendance procedures are still widely used and often generate various problems, including delays in recapitulation, inconsistent data formats, potential duplicate records, and limited access to information required for periodic monitoring. In response to these issues, this study aims to design and evaluate a web-based online attendance application that supports a more systematic, measurable, and accountable attendance management process through login-based user authentication. The methodology includes a needs analysis involving key stakeholders administrators, homeroom teachers, subject teachers, and students which is then translated into a role-based system design. Subsequent stages comprise prototype development, functional testing to ensure feature compliance with specifications, and usability evaluation to assess ease of use and user acceptance. The developed application provides core functionalities such as role-based user management, daily attendance entry, input validation to minimize errors and prevent duplication, and change-history logging (audit trails) to strengthen data integrity and traceability. In addition, the system offers automated recapitulation and attendance trend visualization across daily, weekly, and monthly periods to make monitoring faster and more informative. The system is implemented as a web application using the Laravel framework and a responsive interface to ensure accessibility across multiple devices. Functional testing results indicate that the main features operate as intended, while usability evaluation suggests that the application is easy to use and improves work efficiency compared to manual procedures. Overall, the findings confirm that a web-based attendance system reinforced by data integrity mechanisms and periodic reporting can enhance monitoring effectiveness, accelerate recapitulation processes, and strengthen the accountability of attendance records in schools.

Abstract

Bina Insan Mandiri Islamic Vocational High School has more than 30 years of experience in assisting parents in educating their children through a curriculum that reflects the distinctive characteristics of a modern Islamic school. This activity was initiated in response to the school environment, which generates considerable organic waste from daily activities. The program aimed to provide insight into organic waste management. The target participants of this activity were students of Bina Insan Mandiri Vocational High School, with the objective of providing education and training on the importance of awareness in managing organic waste. The outcomes of this activity included the production of organic fertilizers in both liquid and solid forms for plant cultivation. The outputs of this program consisted of publications in a community service journal, publications in mass media, and a video uploaded to the LPPM UMB YouTube channel. The activity evaluation was conducted by distributing questionnaires to 28 participants. The results showed an expectation score of 4.1 and a performance score of 4.33 on a 5-point scale, indicating the activity was rated satisfactory.
