Abstract

An expert system is a computer-based system that can match or mimic the ability of an expert to solve a problem. This system is designed to mimic the expertise of an expert to answer questions and solve problems in the fields of health or medicine, business, economics and so on. The important role of an expert can be replaced by a computer program whose working principle is to provide solutions as done by the expert. Certainty Factor is a method that defines a measure of certainty of facts or rules to describe an expert's belief in the problem at hand. This system is web-based, so that later this system can be accessed by the wider community online via the internet anywhere and anytime. In dealing with a problem, answers are often found that do not have full certainty.1 This research aims to find out what factors cause the appearance of stomach acid disease through the Certainty Factor method.

Abstract

Penelitian ini bertujuan untuk memodelkan dan membangun Sistem Informasi Absensi Karyawan berbasis web pada Badan Pusat Statistik Provinsi Sumatera Utara (BPS Provsu). Absensi karyawan merupakan aspek kritis dalam menentukan kedisiplinan dan kinerja pegawai, sehingga diperlukan pendekatan teknologi informasi untuk mencatat absensi secara real-time dan efisien. Saat ini, BPS Provsu masih menggunakan metode manual untuk absensi, yang rentan terhadap kesalahan dan kurang efektif. Oleh karena itu, pengembangan sistem informasi absensi berbasis web menjadi solusi yang relevan dan mendesak. Metode pengembangan yang digunakan adalah metode waterfall, yang merupakan model terurut dan sistematik terdiri dari tahapan pengumpulan dan analisis kebutuhan, perancangan sistem, implementasi, pengujian, dan penerapan. Dalam aplikasinya, terdapat dua peran utama, yaitu User (karyawan) dan Admin. User melakukan absensi melalui aplikasi setelah login, dan memiliki akses untuk mengajukan izin absensi secara online. Admin bertanggung jawab untuk memonitor aplikasi, mengelola data karyawan, absensi, jabatan, dan keterangan izin, serta memastikan validitas data yang masuk. Hasil penelitian menunjukkan bahwa aplikasi ini memberikan kemudahan bagi karyawan dalam melakukan absensi dan mengajukan izin, serta meminimalisir kesalahan pencatatan data. Website sebagai bagian dari sistem informasi memberikan informasi yang mudah diakses oleh pengguna yang ingin mengajukan absensi izin atau sakit. Implementasi aplikasi ini juga membantu Admin dalam memonitor dan mengelola data dengan lebih efektif, serta menghasilkan laporan absensi yang akurat dan dapat diandalkan. Penggunaan aplikasi absensi berbasis web meningkatkan efisiensi operasional, meminimalkan risiko kehilangan data, dan memperbaiki proses pengelolaan absensi di BPS Provsu secara keseluruhan.

Abstract

In today's digital landscape, rapid and accurate access to information has become a fundamental requirement for educational institutions. Previously, SMP Swasta Karya Bhakti Medan relied heavily on conventional methods for disseminating information, such as verbal communication or limited printed media. This situation frequently resulted in delays in delivering news to guardians and limited the promotional reach to the broader community. Addressing these issues, this internship project focuses on the design and development of a school profile website as a solution for information digitalization. The system development process involved several stages, including field data collection, user-friendly interface design, and the coding implementation phase. The website is designed to host essential information, ranging from the institutional profile, vision and mission, and facilities, to student activity documentation. To ensure optimal accessibility, the site is hosted using the Netlify service, allowing for continuous online access. The final outcome of this project is a responsive and easily accessible digital information portal. The presence of this website is expected to enhance the school's image and facilitate parents and prospective students in obtaining valid information regarding SMP Swasta Karya Bhakti Medan without distance or time constraints.

Abstract

Public Relations (PR) of the State Islamic University of North Sumatra (UINSU) is a strategic unit that manages various important documents in the institution's administrative and communication activities. However, document loan management in this unit is still done manually, making it vulnerable to data loss, late returns, and difficulty in monitoring document status. This community service research aims to design and implement an integrated web-based document loan information system in the UINSU Public Relations sector. The system was developed using the PHP programming language with a MySQL database, implementing a modern, responsive interface. The system's main features include item/document data management, loan and return recording, and real-time stock monitoring. The results of the community service show that the system is able to improve document management efficiency, reduce recording errors, and make it easier for officers to monitor loan status. This system is expected to become a document asset management model that can be adopted by other units within the UINSU environment.

Abstract

Perancangan Sistem Informasi Profil dan Pubikasi Berita Berbasis Web pada Bagian Kesejahteraan Rakyat (Kesra) Kantor Bupati Kabupaten Deli Serdang bertujuan untuk menyediakan media informasi yang terstruktur, cepat, dan mudah diakses oleh masyarakat. Selama ini, penyampaian informasi terkait program keagamaan, sosial, pendidikan, kesehatan, bantuan kemasyarakatan, serta kegiatan Kesra belum sepenuhnya terdokumentasi dan terpublikasi secara digital. Kondisi ini menyebabkan masyarakat kesulitan memperoleh informasi yang akurat terkait layanan dan program kesejahteraan rakyat. Oleh karena itu, diperlukan sebuah sistem informasi berbasis web yang mampu menampilkan profil instansi, struktur organisasi, program kerja, serta berita kegiatan dengan lebih efektif. Metode pengembangan sistem menggunakan model Waterfall, yang mencakup tahapan analisis kebutuhan, perancangan, implementasi, pengujian, dan dokumentasi. Sistem dirancang menggunakan teknologi HTML, CSS, PHP, JavaScript, dan MySQL untuk menghasilkan platform yang responsif, informatif, dan mudah dikelola oleh administrator Bagian Kesra. Hasil perancangan menunjukkan bahwa sistem informasi ini mampu menyajikan informasi profil Kesra, publikasi berita, agenda kegiatan, dan layanan masyarakat secara terorganisasi dan mudah dipahami. Rancangan ini diharapkan menjadi acuan dalam pembangunan sistem yang sesungguhnya sehingga dapat meningkatkan efektivitas penyebaran informasi serta mendukung transparansi Pemerintah Kabupaten Deli Serdang dalam bidang kesejahteraan rakyat.
