Abstract

In modern life, internet access has become essential for communication. Email is one of many communication tools. Cyberattacks such as ransomware, phishing, and cryptojacking continue to evolve and are difficult to detect by security systems as technology rapidly advances. Therefore, this study uses email spam as the subject of research. The aim of this study is to implement and calculate the accuracy of the K-Nearest Neighbors (KNN) algorithm in classifying spam emails with ham and spam labels. An accuracy of 85%, precision of 87%, recall of 93%, and F1-score of 90% were obtained from tests conducted with an 80% training data and 20% testing data ratio. The results show that the K-Nearest Neighbors algorithm can effectively classify spam emails.

Abstract

The development of information technology has progressed rapidly as humans interact with the internet through mobile devices and computers. These advancements enhance performance and enable various activities to be carried out quickly, accurately, and efficiently, thereby increasing productivity. In Indonesia, rapid technological growth coincides with a rising population, which leads to an increase in waste volume. Waste is the residual material from human activities or natural processes in solid form, generated daily. To address waste management issues, the establishment of waste banks has become an alternative solution. Waste banks serve as collection centers for sorted waste and are also used in social planning to educate the community on environmental health, encourage behavioral changes at the household level the main source of waste and support the implementation of a circular economy. As a result, the community benefits both ecologically and financially. To improve the effectiveness of waste bank management, an Android-based Waste Bank Application using the Prototype Method is proposed. This system provides general information about waste banks and enables customers to monitor deposit and withdrawal transactions in real time through an online savings book. The mobile-based application can be accessed from various smartphones connected to the internet, facilitating waste bank management and encouraging community participation in waste management programs.

Abstract

This research aims to design and implement a Vue.js-based online attendance application for PT. PPILN. The main objective is to enhance the efficiency of field technicians in recording their attendance. The application replaces the traditional method of using pen and paper, which is time-consuming and requires administrative resources. The research includes the analysis of requirements and the design of a responsive and user-friendly online attendance application. The implementation results demonstrate improved efficiency in attendance recording for field technicians, allowing them to record their attendance directly in the field. The application also minimizes the risk of errors and enables real-time tracking of the technicians' whereabouts by the management of PT. PPILN. The RAD research method will be utilized in this study. The data used will be internal data from PT. PPILN concerning the technical staff and the attendance process.

Abstract

C.V Megah Pelita Bangsa merupakan bidang yang bergerak dalam pengelolaan parkir di Universitas Pelita Bangsa Cikarang. Dalam menentukan pengeloaan parkir harus dibutuhkan sistem klasifikasi dikarenakan sulitnya petugas dalam menentukan lahan parkir yang akan digunakan karena banyaknya kendaran sehingga mengakibatkan penumpukan kendaraan. Oleh karena itu harus ada sistem pengambil keputusan yang dapat mengatasi masalah tersebut. Penelitian ini bertujuan untuk menentukan lahan parkir menggunakan data mining dan algoritma naïve bayes. Pada hasil klasifikasi 180 data yang di uji menggunakan metode naïve bayes menghasilkan tingkat akurasi sebesar 96%

Abstract

Penelitian ini membahas penerapan metode prototype dalam pengembangan aplikasi pengecekan dan perawatan jig berbasis website pada PT Yamaha Music Manufacturing Asia, perusahaan manufaktur alat musik elektronika dan pro audio di Kabupaten Bekasi. Permasalahan yang dihadapi adalah proses pengecekan dan pendataan jig di Departemen Produksi, khususnya section FA (Final Assy), yang masih dilakukan secara manual sehingga kurang efektif dan efisien. Penelitian ini bertujuan mengembangkan sistem informasi terkomputerisasi yang dapat membantu operator dalam pendataan jig serta memudahkan Staff Admin produksi dalam penyusunan laporan. Sistem dikembangkan menggunakan bahasa pemrograman PHP dan basis data MySQL dengan pendekatan metode prototype agar dapat menyesuaikan kebutuhan pengguna secara bertahap. Hasil penelitian berupa sistem informasi pengecekan dan pendataan jig berbasis web yang mampu meningkatkan efektivitas dan efisiensi proses pengolahan data.
