Sistem Informasi Berbasis Web untuk Pengelolaan Jadwal Pekerjaan di PT Temprina Media Grafika Surabaya
Get PDFPT Temprina Media Grafika Surabaya, one of the largest printing companies in Indonesia, faces challenges in managing job schedules manually. The current management methods, which rely on spreadsheets or instant messaging for communication, often lead to inefficiencies, recording errors, and a lack of information transparency. To address these issues, a web-based information system was developed to enhance job scheduling efficiency, facilitate inter-division communication, and streamline workflows.
The system was built using the CodeIgniter 3 framework with a Model-View- Controller (MVC) architecture to ensure structured and maintainable code management. A MySQL database was employed to securely and efficiently store and manage job-related data, while the system interface was designed responsively with Bootstrap to deliver an optimal user experience. Key features of the system include job schedule management, such as adding, editing, deleting (CRUD), and real-time job status tracking. Additionally, data validation mechanisms were implemented to minimize input errors, and system-based notifications were incorporated to remind users of scheduled tasks.
The development process followed several main stages: requirement analysis, system design, feature implementation, and testing. The requirement analysis phase involved direct observation at PT Temprina Media Grafika to understand workflow and challenges. System design was represented using use case and sequence diagrams to map user interactions with the system. The implementation phase included coding core modules, component integration, and database configuration. The system underwent functional testing to ensure features met specifications and was tested in a real work environment to validate its alignment with the company’s operational needs.
The development results demonstrated that the web-based information system effectively improved job scheduling efficiency, reduced errors caused by manual records, and provided faster and more transparent data access for employees and management. Additionally, the system enabled systematic storage of historical job data, which is valuable for future performance analysis and evaluation.
Further development could include implementing scheduling automation using specific algorithms or integrating third-party services, such as reminders via SMS or email. This would allow the system to evolve continuously, contributing significantly to the digitalization of work processes at PT Temprina Media Grafika

PERBANDINGAN KEMAMPUAN MEDIA KOMBINASI BIOCHAR, SILIKA DAN ZEOLIT SEBAGAI ADSORBEN DALAM FLUIDIZED BED REACTOR UNTUK PENGOLAHAN LIMBAH ELEKTROPLATING
No full textElectroplating waste contains hazardous heavy metals such as lead (Pb) and nickel (Ni), as well as suspended solids (TSS) that can pollute the environment. This study aims to analyze the effect of variations in the combination of adsorbent media (zeolite, zeolite + biochar, and zeolite + silica), flow rate (33 L/min and 55 L/ min), and contact time (30, 60, and 90 min) on the removal efficiency of Pb, Ni, and TSS using a Fluidized Bed Reactor (FBR). The acrylic reactor was operated with a media mass of 200 grams under batch conditions, and waste samples were taken from an electroplating industry in Gresik. The results showed that an increase in contact time was directly proportional to removal efficiency, with the highest performance at 90 minutes for Pb and Ni metals, while TSS was optimal at 60 minutes. Media variations showed significant differences: pure zeolite was most effective in reducing Ni (up to 90.5%), the zeolite+silica combination excelled in Pb removal (up to 99%), while the zeolite+biochar combination was more dominant in reducing TSS at low flow rates. Flow rate also had an effect, with 55 L/min increasing fluid distribution and adsorbent contact, especially for heavy metals. Overall, the combination of media in the FBR proved to be effective and environmentally friendly, and has the potential to be applied as an alternative technology for electroplating waste treatment in Indonesia
