Fatia Amalia Maresti — 2025-02-24

Retail companies are one form of business that has experienced significant development. Significant development can lead to many business competitors in the same field. Therefore, every company must be able to find strategies to get the attention of the target market. Fast service and good prices are included in the factors that influence customer interest in making transactions in the retail business. This research aims to classify products into several categories. The method used to perform segmentation is the data mining method with the K-Means algorithm and the elbow method to find the optimal number of clusters. The obtained results of many optimal clusters are 3, namely cluster 0, cluster 1, and cluster 2. The variable that has the most influence on cluster characteristics is the price variable, while the variable that has little influence on cluster characteristics is the quantity variable.

Prototype Pintu Air Irigasi Otomatis Berbasis Internet Of Things

Erwan Darmawan — 2025-02-24

Abstract

A sluice gate is a supporting structure in a dam, reservoir, river, gutter or ditch which functions to regulate the control of water discharge in each flow. With good and controlled irrigation, irrigation systems and waterways from upstream to downstream can be controlled, so that the need for water in agriculture, fisheries, plantations, and industry can be met and relied on properly. The sluice gate functions to control water so that it can prevent flood water in a fast and high flow. The flowing water will lead to the river to the ocean. Therefore the author will design a prototype of an Internet of Things (IoT) based automatic sluice monitoring system. this system requires interrelated components, namely NodeMcu as the control center of the system as well as a wifi module and the relay module as an electrical switch to turn on or off and use the blynk application.

Penggunaan Machine Learning untuk Memprediksi Paparan PM2.5 dan Dampaknya terhadap Kesehatan

Lita Widiastuti — 2025-02-27

Penurunan kualitas udara di Indonesia akibat penggunaan bahan bakar fosil menyebabkan tingginya konsentrasi PM2.5, yang berisiko bagi kesehatan masyarakat. Penelitian ini menggunakan metode machine learning untuk menganalisis faktor-faktor yang mempengaruhi kualitas udara terhadap kesehatan serta memprediksi paparan PM2.5 dan biaya kesejahteraan akibat kematian dini karena polusi udara. Metode penelitian yang digunakan CRISP-DM yang meliputi pengumpulan, pemahaman, dan persiapan data, pemodelan, evaluasi, serta penerapan. Data diambil dari OECD periode 1994–2022. Hasil analisis menunjukkan peramalan paparan PM2.5 diproyeksikan meningkat dalam 8 tahun mendatang, memicu peningkatan biaya kesejahteraan akibat dampak kesehatan yang dapat menyebabkan gangguan pernapasan dan kematian dini. Model ARIMA digunakan untuk memprediksi paparan PM2.5, sedangkan ARIMAX+ETS memprediksi biaya kesejahteraan, dengan peningkatan akurasi setelah hyperparameter tuning. Untuk mengatasi hal ini, direkomendasikan kebijakan seperti penerapan teknologi ramah lingkungan, transisi energi bersih, pengelolaan limbah, dan pembangunan kota hijau sehingga diharapkan dapat mengurangi polusi udara dan menekan biaya kesejahteraan di masa depan.

Analisis Perbandingan Implementasi Protokol Routing Dinamis Open Shortest Path First (OSPF) dan Border Gateway Protocol (BGP) pada Lab Komputer Menggunakan Cisco Packet Tracer

Alim Hardiansyah — 2025-03-20

Abstract

Computer networks in the current era of globalization have developed very rapidly and are increasingly used by agencies around the world, which require effective routing protocols. One network that is often used is the internet, which has dynamic routing protocols such as Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP). In this study, researchers conducted a network topology simulation design in sending data packets using OSPF and BGP. The purpose of this research is to analyze the performance comparison of the two dynamic protocols in a computer network simulation using Cisco Packet Tracer. The analysis results show that OSPF excels with low delay (12 ms), stable jitter (13.5 ms), and moderate throughput (25.58kbps), making it more suitable for real-time applications, while BGP shows better reliability with low packet loss (8.3%).

Keywords: Routing, OSPF, BGP, Computer Network, Cisco Packet Tracer

SISTEM Sistem Pendukung Keputusan Seleksi Siswa Calon SDM Menggunakan Metode AHP

Ahmad Rufai — 2025-03-20

Peran divisi Sumber Daya Manusia (SDM) adalah menjalin Kerjasama dengan Lembaga/Sekolah Pendidikan. Dalam Kerjasama ini Perusahaan (divisi Sumber Daya Manusia) menyerahkan diri sepenuhnya kepada Lembaga Pendidikan/sekolah untuk berperan dalam pemilihan calon mahasiswa SDM yang berkualitas. SMK meriupakan salah satu Lembaga Pendidikan yang berkerja sama dengan beberapa Perusahaan. SMK yang berfungsi sebagai wadah untuk mengembangkan kemampuan dan seleksi calon mahasiswa Sumber Daya Manusia yang akan diberikan bekal dan persiapan untuk bekerja disuatu Perusahaan. Di setiap Perusahaan / instansi proses penerimaan Sumber Daya Manusia masih belum dilakukan secara profesional, melainkan dilakukan dengan cara penyuapan, pertemanan, atau hubungan keluarga. Hal ini terjadi karena tidak ada metode standar yang sistematis untuk menilai kelayakan calon SDM.
