Abstract

The sales achievement monitoring process at CV Pakar Prima Buana, which relies on Microsoft Excel, has led to issues such as data duplication and inconsistency due to the manual filtering and target distribution performed by team leaders in a company with over 500 employees. This study aims to develop a web-based information system designed to simplify, accelerate, and streamline the monitoring of each salesperson’s achievement performance. The Rapid Application Development (RAD) methodology was adopted for its fast and adaptive development cycle, consisting of three main phases: Requirements Planning, Design Workshop, and Implementation. The system was developed using PHP, the CodeIgniter framework, and a MySQL database. The black-box testing results demonstrate that all system functions operate as expected. The resulting system successfully automates the calculation and reporting of sales achievements, eliminates data duplication, and provides structured, accurate, and timely information to support managerial decision-making. Keywords: Information System, Sales Achievement, Rapid Application Development, CodeIgniter, Black-box Testing

Abstract

Penelitian ini bertujuan untuk merancang dan mengimplementasikan Sistem Pendukung Keputusan (SPK) dalam proses seleksi karyawan terbaik di PT. XYZ menggunakan algoritma Random Forest. Permasalahan utama yang dihadapi perusahaan adalah proses penilaian karyawan yang masih dilakukan secara manual melalui Microsoft Excel, sehingga rawan terhadap kesalahan perhitungan, duplikasi data, serta memerlukan waktu yang lama untuk menentukan karyawan berprestasi. Untuk mengatasi hal tersebut, penelitian ini mengusulkan penerapan sistem berbasis web yang terintegrasi dengan model klasifikasi machine learning guna meningkatkan efisiensi dan objektivitas proses evaluasi. Metode penelitian yang digunakan meliputi tiga tahap pengumpulan data, yaitu studi pustaka, observasi, dan wawancara. Proses pengembangan sistem dilakukan menggunakan model Software Development Life Cycle (SDLC) dengan pendekatan Waterfall, yang mencakup tahapan perencanaan, analisis kebutuhan, perancangan sistem, implementasi, pengujian, dan pemeliharaan. Hasil implementasi menunjukkan bahwa sistem mampu menampilkan hasil penilaian karyawan berdasarkan empat kriteria utama: kedisiplinan, kinerja, sikap kerja, dan keahlian, yang kemudian diolah menggunakan algoritma Random Forest untuk menentukan peringkat akhir. Hasil pengujian menunjukkan bahwa penerapan metode Random Forest memberikan tingkat akurasi yang tinggi dalam proses klasifikasi dengan nilai akurasi mencapai 91,2%, serta menghasilkan peringkat karyawan yang konsisten dengan hasil evaluasi HRD. Sistem ini juga dilengkapi dengan antarmuka pengguna yang sederhana dan informatif, yang memudahkan admin, HRD, dan karyawan dalam mengakses informasi sesuai hak akses masing-masing. Secara keseluruhan, penerapan algoritma Random Forest dalam sistem pendukung keputusan ini terbukti efektif dalam meningkatkan kecepatan, objektivitas, dan transparansi proses penilaian karyawan di PT. XYZ.

Abstract

Weather is formed from a group of weather elements and can be changed fast. For example, in the morning, afternoon, or evening, the weather can be different for each place and every hour. Weather is the condition of the air that occurs in a narrow place and lasts for a short time. Weather conditions in a place can be determined by many factors, such as air pressure, humidity, wind, sunlight, and so on. Therefore, by looking at these factors it can be estimated the weather that will occur the next day. Fishermen and farmers are fields of work that are closely related to weather forecasting, accurate and fast weather predictions are needed by these fields to carry out various activities. The amount of rainfall that occurs cannot be determined exactly but can be predicted or estimated. The application of determining weather information is needed, hence, the prediction can be utilized optimally by the community. The design of a system that will classify automatically can be developed by applying machine learning methods, one of them is used in this study, i.e., C.4.5 Algorithm using weather data that a reference in determining the weather conditions whether not rainy, rainy, light rain, or heavy rain.
