Siahaanapaansi55@gmail.comAdi Prijuna Lubispri7n4@gmail.comWan Mariatul Kiftikifti.inti@gmail.com<p><strong>Abstract: </strong>Semangat Store, a rapidly growing retail store in Kisaran, faces challenges in inventory management due to its manual system. Ordering is done by contacting suppliers individually, and sales data is recorded conventionally in a general ledger. As a result, the store often experiences overstock, which increases storage costs and the risk of damaged goods, or stockouts that can disappoint customers. To address these issues, this study aims to implement an integrated, web-based Supply Chain Management (SCM) system. This system is designed to accurately record inventory, manage demand, place orders in a timely manner, and support fast, data-driven decision-making. The system was built using the PHP programming language and a MySQL database. The implementation results show that the proposed SCM system is able to improve operational efficiency and inventory management accuracy at Semangat Store. Store owners can monitor sales and order reports directly, and the system provides notifications when inventory reaches the minimum limit. Thus, Semangat Store can reduce the risk of overstocking or understocking, increase profitability, and simplify the restocking process with suppliers through a more structured system.</p> <p> <br><strong>Keyword</strong><strong>s:</strong> supply chain management (<strong>scm</strong>); stock management; information systems; semangat store</p> <p><strong>Abstrak: </strong>Toko Semangat, sebuah toko ritel yang berkembang pesat di Kisaran, menghadapi tantangan dalam pengelolaan stok barang karena masih menggunakan sistem manual. Proses pemesanan barang dilakukan dengan menghubungi pemasok satu per satu, dan pencatatan data penjualan masih dilakukan secara konvensional di buku besar. Akibatnya, toko sering mengalami kelebihan stok (over stock) yang meningkatkan biaya penyimpanan dan risiko kerusakan barang, atau kekurangan stok yang dapat mengecewakan pelanggan. Untuk mengatasi masalah ini, penelitian ini bertujuan untuk mengimplementasikan sistem Supply Chain Management (SCM) yang terintegrasi dan berbasis web. Sistem ini dirancang untuk mencatat stok barang secara akurat, mengelola permintaan, melakukan pemesanan secara tepat waktu, serta mendukung pengambilan keputusan yang cepat dan berbasis data. Sistem ini dibangun menggunakan bahasa pemrograman PHP dan database MySQL. Hasil dari implementasi menunjukkan bahwa sistem SCM yang diusulkan mampu meningkatkan efisiensi operasional dan akurasi pengelolaan stok barang di Toko Semangat. Pemilik toko dapat memantau laporan penjualan dan pemesanan secara langsung, dan sistem memberikan notifikasi jika stok barang mencapai batas minimum. Dengan demikian, Toko Semangat dapat mengurangi risiko kelebihan atau kekurangan stok, meningkatkan profitabilitas, dan mempermudah proses restock dengan pemasok melalui sistem yang lebih terstruktur.</p> <p><strong>Kata kunci: </strong>supply chain management (<strong>scm</strong>); pengelolaan stok; sistem informasi; toko semangat</p>2025-11-07T00:00:00+00:00Copyright (c) 2025 J-Com (Journal of Computer)https://jurnal.stmikroyal.ac.id/index.php/j-com/article/view/4207Perancangan Sistem Informasi Geografis Pemetaan Peninggalan Belanda Di Kota Padang2025-12-25T07:37:06+00:00restu resturestu0203@gmail.comMelladia MelladiaMelladia@gmail.com<p><strong>Abstract:</strong> Padang City holds various historical relics from the Dutch colonial era, which possess significant historical value and high tourism potential. However, information regarding the locations and descriptions of these relics is still scattered and difficult to access in an integrated manner. This study aims to design and implement an Android-based Geographic Information System (GIS) that presents an interactive map containing the locations, descriptions, and photos of the heritage sites, along with a regional filter feature to facilitate navigation. The development process began with data collection from the Tourism Office and field observations, followed by map processing in ArcMap, publication to ArcGIS Online, and the creation of an Android application using ArcGIS Maps SDK and Jetpack Compose. Integration with a MySQL database allows the automatic display of location points on the map. The implementation results show that the application can display 33 heritage site points in three districts of Padang City, complete with descriptions, photos, district filters, and Web Map integration. Testing demonstrated that the application runs smoothly, is informative and interactive, and can support cultural preservation efforts while encouraging interest in historical tourism in Padang City.</p> <p><strong>Keyword</strong><strong>s:</strong> geographic information system; dutch heritage; arcgis; android; padang city.</p> <p><strong>Abstrak:</strong> Kota Padang menyimpan berbagai peninggalan bersejarah dari masa kolonial Belanda yang memiliki nilai sejarah dan potensi wisata tinggi.

Penelitian ini bertujuan merancang dan mengimplementasikan Sistem Informasi Geografis (SIG) berbasis Android yang menyajikan peta interaktif berisi lokasi, deskripsi, foto peninggalan, serta dilengkapi fitur filter wilayah untuk memudahkan penelusuran. Proses pengembangan diawali dengan pengumpulan data dari Dinas Pariwisata dan observasi lapangan, dilanjutkan dengan pengolahan peta di ArcMap, publikasi ke ArcGIS Online, serta pembuatan aplikasi Android menggunakan ArcGIS Maps SDK dan Jetpack Compose. Integrasi dengan basis data MySQL memungkinkan penampilan titik lokasi secara otomatis pada peta. Hasil implementasi menunjukkan aplikasi mampu menampilkan 33 titik peninggalan di tiga kecamatan di Kota Padang, lengkap dengan deskripsi, foto, filter kecamatan, dan integrasi Web Map. Hasil pengujian membuktikan aplikasi berjalan lancar, informatif, dan interaktif sehingga dapat mendukung upaya pelestarian budaya, dan mendorong peningkatan minat wisata sejarah di Kota Padang.</p> <p><strong>Kata kunci:</strong> sistem informasi geografis; peninggalan belanda;arcgis; android; kota padang</p>2025-11-09T00:00:00+00:00Copyright (c) 2025 J-Com (Journal of Computer)https://jurnal.stmikroyal.ac.id/index.php/j-com/article/view/4162Implementasi E-Crm Di Ria Reklame Guna Meningkatkan Sektor Penjualan Jasa Cetak Undangan2025-12-25T07:58:11+00:00Fadhil Nur Afif Sihombingfadhilshb03@gmail.comNofriadi Nofriadinofriadi.royal85@yahoo.comRohminatin Rohminatinarfadewi@yahoo.co.id<p><strong>Abstract: </strong><em>The increasingly competitive economic growth requires business actors to innovate in their business strategies in order to survive and develop. Ria Reklame Store, a printing business specializing in invitation cards established in 2008, faces several challenges, including limited promotion methods, a manual ordering process, and unorganized transaction recording. These conditions have resulted in limited market reach and inefficient data management. This study aims to implement Electronic Customer Relationship Management (E-CRM) as a digital strategy to enhance operational effectiveness and sales performance at Ria Reklame. By utilizing website-based technology, the store can reach a wider range of customers, simplify the ordering process, and manage transaction data in a more structured and secure manner.
