Abstract

The study focuses on the development of an antibacterial film derived from carboxymethyl cellulose (CMC) obtained from gebang leaves (Corypha utan), aiming to contribute to sustainable development in North Padang Lawas. The carboxymethyl cellulose was extracted from gebang leaves and utilized as a base material for film preparation. To enhance the film’s properties, carboxymethyl cellulose was combined with polyvinyl alcohol (PVA) and crosslinked with citric acid. The resulting films were evaluated for their antibacterial activity, specifically against Escherichia coli and Staphylococcus aureus. The films demonstrated significant antibacterial effects and improved water resistance with increased citric acid content. Additionally, the films exhibited a three-dimensional structure, porous network, and low toxicity, making them suitable for biomedical applications. This work underscores the potential of utilizing local plant resources for sustainable material development in North Padang Lawas, aligning with environmental and economic sustainability goals.Penelitian ini berfokus pada pengembangan film antibakteri yang berasal dari karboksimetil selulosa (CMC) yang diperoleh dari daun gebang (Corypha utan), dengan tujuan untuk berkontribusi pada pembangunan berkelanjutan di Padang Lawas Utara. Karboksimetil selulosa diekstraksi dari daun gebang dan digunakan sebagai bahan dasar untuk pembuatan film. Untuk meningkatkan sifat film, karboksimetil selulosa dikombinasikan dengan poli(vinil alkohol) (PVA) dan dilakukan penghubungan silang dengan asam sitrat. Film yang dihasilkan dievaluasi aktivitas antibakterinya, khususnya terhadap Escherichia coli dan Staphylococcus aureus. Film menunjukkan efek antibakteri yang signifikan dan ketahanan air yang meningkat dengan penambahan asam sitrat. Selain itu, film menunjukkan struktur tiga dimensi, jaringan berpori, dan toksisitas rendah, menjadikannya cocok untuk aplikasi biomedis. Pekerjaan ini menegaskan potensi pemanfaatan sumber daya tanaman lokal untuk pengembangan material yang berkelanjutan di Padang Lawas Utara, selaras dengan tujuan keberlanjutan lingkungan dan ekonomi.

Abstract

On the persentation of information which was presented by SMK SATRIA Jambi was still using the conventional method, This information was obtained from particular medias or straight to the scholl. With the result that infomation conveyed effective and efisition. Based on that case a web base information system program was designed. It is expected through this system, the ineffectiveness and the shortcoming in term of information system which exists can be minimized can be easly accessed by people who want to know the information which in SMK SATRIA Jambi as well as the new candidate of new students who will enroll at SMK SATRIA Jambi will make them easier by only filling the given form. The method used in the development of the system is the Waterfall method. While the system modeling tools used by the author is the Use Case Diagrams, Activity Diagrams and Class Diagrams. The programming language used in the design of the SMK Satria Jambi Website is using php and MySQL DBMS. With the programming language that can facilitate the development of the website at SMK Satria Jambi. Being able to facilitate the school in informing profile, achievements, and various other important activities of the school and overcome the old system.

Abstract

Abstract: The development of information technology encourages companies to adapt by implementing more effective and efficient systems, including in the management of employee data. This study aims to analyze and design a web-based employee data management information system at PTPN IV Regional II Gunung Bayu Plantation as a solution to administrative problems that were previously handled manually. The system development method used is the Waterfall model, which consists of the stages of requirements analysis, system design, implementation, testing, and maintenance. Data collection was carried out through direct observation, interviews with related parties, and analysis of documents related to the employee data management process.The results of the study indicate that the developed system is able to improve administrative efficiency, accelerate data processing, and minimize input errors and data duplication. Furthermore, this web-based system provides easier real-time access to information and supports transparency among organizational units. With a simple and responsive user interface, the system can be easily operated by the human resources department. Overall, the implementation of the web-based employee data management information system has proven to enhance administrative performance and support the application of good corporate governance principles.

Studi ini bertujuan untuk menganalisis dan merancang sistem informasi pengelolaan data karyawan berbasis web di PTPN IV Regional II Kebun Gunung Bayu sebagai solusi terhadap permasalahan administrasi yang sebelumnya ditangani secara manual. Metode pengembangan sistem yang digunakan adalah model Waterfall, yang terdiri dari tahapan analisis kebutuhan, desain sistem, implementasi, pengujian, dan pemeliharaan. Pengumpulan data dilakukan melalui observasi langsung, wawancara dengan pihak terkait, dan analisis dokumen yang berkaitan dengan proses pengelolaan data karyawan. Hasil penelitian menunjukkan bahwa sistem yang dikembangkan dapat meningkatkan efisiensi administrasi, mempercepat pengolahan data, dan meminimalkan kesalahan input dan duplikasi data. Lebih lanjut, sistem berbasis web ini memberikan akses informasi secara real-time yang lebih mudah dan mendukung transparansi antar unit organisasi. Dengan antarmuka pengguna yang sederhana dan responsif, sistem ini dapat dioperasikan dengan mudah oleh departemen sumber daya manusia. Secara keseluruhan, implementasi sistem informasi pengelolaan data karyawan berbasis web telah terbukti meningkatkan kinerja administrasi dan mendukung penerapan prinsip-prinsip tata kelola perusahaan yang baik.
