Abstract

Usaha Mikro, Kecil, dan Menengah (UMKM) merupakan salah satu elemen penting untuk mengembangkan perekonomian masyarakat Desa Gunung Selamat. Hal ini dibuktikan dengan keberadaan UMKM sejumlah 1 UMKM Mayarakat lokal dan 2 UMKM baru dari Mahasiswa Pengabdian Kepada Mayarakat yang sedang  di Desa Gunung Selamat (Gunung Selamat, 2023). Dari sekian jumlah tersebut, UMKM yang melaju pesat perkembangannya adalah UMKM pengolahan kerupuk Jange. Perkembangan UMKM yang begitu pesat tersebut, memacu kepercayaan masyarakat Desa Gunung Selamat  untuk membranding Desanya dengan dibantu Mahasiwa/i menjadi Desa Gunung Selamat -ekonomi kreatif. Metode pelaksanaan kegiatan adalah dengan mengunjungi UMKM Kerupuk Jangek tersebut  secara langsung dengan didampingi oleh Ketua PKK Desa Gunung Selamat  beserta timnya. Hasil kegiatan Pengabdian kepada Masyarakat bertujuan untuk memberikan Penyuluhan Strategi Pemasaran Bisnis UMKM Desa Gunung Selamat, Kecamatan Bilah Hulu, Kabupaten Labuhan Batu, Provinsi Sumatera Utara. Dengan demikian, UMKM sebagai pilar perekonomian Desa Gunung Selamat dapat berkembang dan diketahui masyarakat luas yang berkunjung ke Desa Gunung Selamat  dengan lebih baik sehingga kesejahteraan masyarakatnya akan semakin meningkat. Rekomendasi untuk peningkatan mitra, UMKM Desa Gunung Selamat harus menerus berinovasi mengembangkan produk unggulannya serta memperluas jaringan pemasarannya baik secara langsung bertemu dengan pelanggannya maupun melalui pemasaran digital platform.

Abstract

Keamanan jaringan komputer merupakan hal yang sangat penting dalam menjaga kelangsungan operasional sistem informasi, terutama pada organisasi skala menengah. Penelitian ini bertujuan untuk mengimplementasikan sistem keamanan jaringan berbasis open source dengan menggabungkan penggunaan firewall iptables dan Intrusion Detection System (IDS) Snort. Metode yang digunakan adalah pendekatan eksperimental, yang meliputi perancangan topologi jaringan, instalasi perangkat lunak keamanan, simulasi serangan siber, serta evaluasi kinerja sistem. Hasil pengujian menunjukkan bahwa kombinasi iptables dan Snort mampu mendeteksi dan memblokir ancaman seperti port scanning, ping flood, dan brute force login dengan akurasi tinggi dan tingkat false positive yang rendah. Penelitian ini membuktikan bahwa kombinasi Snort dan iptables sebagai solusi open-source mampu mendeteksi serta memblokir serangan umum dengan akurasi tinggi dan false positive yang rendah, sehingga layak diimplementasikan pada jaringan skala kecil-menengah. Kontribusi penelitian ini adalah memberikan alternatif keamanan yang efektif, ekonomis, dan dapat dijadikan dasar bagi pengembangan lebih lanjut menggunakan anomaly-based detection atau pembelajaran mesin.

Abstract

The implementation of a Web-Based Library Information System at the Rantauprapat Public Library aims to increase efficiency and effectiveness in managing library resources. This information system integrates various library functions, such as book cataloging, borrowing, returns, and member management, into a single web-based platform. By using web-based technology, libraries can make access easier for visitors to search for information and borrow online, without being limited by time and place. This research identifies the system's technical and functional requirements and evaluates its impact on library services and visitor satisfaction. The results of implementing this system show an increase in data accuracy, a reduction in service times, and a reduction in administrative errors. Apart from that, this system also makes it easy for visitors to access library information more efficiently. It is hoped that the implementation of this web-based library information system can become a model for other libraries in an effort to improve the quality of library information services in the digital era.

Abstract

The development of information technology and data analytics has encouraged business actors to leverage historical data as a basis for decision-making. In the small and medium enterprise (SME) sector, particularly in the culinary field, the ability to predict sales is a crucial aspect of production planning and stock management to ensure operational efficiency. Rayyan Bakery Simpang Marbau, as a bakery SME, faces challenges due to fluctuating sales that have traditionally been managed based on experience rather than systematic data analysis. The main problem addressed in this study is the absence of a data-driven sales prediction method that can assist the business owner in estimating sales accurately. Therefore, a predictive approach that utilizes historical sales data is required to support managerial decision-making. This study employs linear regression and decision tree methods. The analyzed data consist of historical sales records of Rayyan Bakery Simpang Marbau over a specific period. Linear regression is used to model the linear relationship between sales variables, while the decision tree captures non-linear patterns and produces easily interpretable decision rules. The performance of both methods is analyzed and compared based on the accuracy of the predictions they generate. The results indicate that both linear regression and decision tree methods can be effectively used to predict sales; however, the decision tree provides greater flexibility in capturing fluctuating sales patterns. These findings are expected to assist Rayyan Bakery in production planning and stock management, as well as serve as a reference for applying sales prediction methods in similar SMEs.
