Abstract

The assessment of student learning outcomes is a mandatory process in educational institutions, whether they are formal or non-formal, with the aim of monitoring and evaluating student progress during the learning process. With the advancement of technology, there are many processes that can be integrated with information technology to simplify existing procedures. The purpose of this research is to facilitate schools in making decisions regarding the results of the learning assessment process by using predefined attributes. The attributes used as reference for consideration are assignments, mid-term exams (UTS), and final exams (UAS). Therefore, this study is built using the SAW method and the PHP programming language supported by the Laravel framework. The output of this research is an information system that supports decision-making in assessing student learning outcomes in the form of subject rankings and provides transparency and convenience for students to access their grades or the final results of the student learning assessment process.

Customer satisfaction determines whether they continue to use the service, while customer dissatisfaction leads to them stopping using it. The result will be the loss of customers for business actors. Developing strategies to improve the satisfaction of customers is one of the most important tasks for business actors. Essentially, C4.5 is a decision tree algorithm that functions in the form of a structured data collection program coded in such a way that it can be used to collect data that has changed and to turn it into a decision tree that consists of a decision rule so that the results of the data can be used to help make a decision. Based on the findings of the research, it appears the factors that are influencing Edukits Batam Center customer satisfaction the most are price, the accessibility of the location, and the quality of the products.

Abstract

Facing the dynamics of a competitive and rapidly changing business environment, PT Prima Niaga Indomas, a snack food distribution company, encounters challenges in optimizing its product sales. Accurate sales forecasting is crucial to maintaining inventory efficiency, avoiding overstock, and meeting customer demand. This research aims to implement the C4.5 algorithm to predict the sales of snack food products at PT Prima Niaga Indomas. The location of PT Prima Niaga Indomas is at Puri Industrial Park 2000 Block D No. 5, Batam Centre, Batam City, Riau Islands. By leveraging historical sales data, product information, marketing factors, and external variables, this study seeks to develop a predictive model to assist the company in forecasting snack food product sales more accurately. The data generated from this research is expected to make a significant contribution to improving the operational efficiency of PT Prima Niaga Indomas. Data analysis is conducted by applying the C4.5 algorithm using WEKA software version 3.8.5, with manual calculations for comparison using Microsoft Excel. The research findings indicate the accuracy of data in the rules of delivery, durability, price, size, and quality. The researchers utilized two decision variables, namely, whether a product is sold or not. This study provides valuable insights into optimal inventory management, identification of sales trends, and faster responsiveness to market changes.

Abstract

Penelitian ini bertujuan untuk menganalisis kualitas layanan sebuah website untuk mengetahui perbedaan antara harapan dan persepsi ideal pengguna website. Masalah yang harus dipecahkan adalah bagaimana memulai mengevaluasi sebuah situs web. Pendekatan terukur WebQual dipilih karena merupakan teknik langsung ke pengguna di mana pengukuran kualitas situs web didasarkan pada persepsi. WebQual yang digunakan adalah WebQual versi 4.0 yang telah dimodifikasi dengan menambahkan dimensi User Interface Quality dengan tiga dimensi utama yaitu Quality of Usability, Quality of Information, dan Quality of Service Interaction. Analisis statistik menggunakan analisis perbedaan (differences t-test) dan Importance Performance Analysis (IPA). Hasil penelitian membuktikan bahwa terdapat perbedaan persepsi dan harapan terhadap layanan website, hal ini menunjukkan bahwa tingkat kualitas layanan website belum memenuhi harapan konsumen. Hasil pemetaan pada diagram kartesius tersebut memuat 7 indikator penting yang diharapkan dapat menjadi masukan bagi manajemen pengelola website dalam merumuskan strategi peningkatan kualitas website.

Abstract

Pengambilan keputusan pasti akan dialami setiap orang kapan saja dan dimana saja, persoalan akan muncul jika keputusan yang diambil memerlukan beberapa pertimbangan karena jika tidak diperhitungkan dan dipertimbangkan secara baik maka akan berimbas kepada kepada hasil akhir yang buruk dan beresiko. Pembahasan dalam penelitian ini berhubungan dengan proses pengambilan keputusan yaitu keputusan untuk pembelian sebuah laptop menggunakan fungsi Borda. Fungsi Borda dikenal sebagai suatu pembobotan (mirip dengan AHP) dengan menggunakan data preferensi atau peringkat kepentingan dari atribut (variabel) yang akan dibobotkan. Adapun atribut yang diambil adalah menyangkut masalah komponen utama, ukuran, harga, touchpad, baterai, merek dan sistem operasi dari sebuah laptop. Dari 7 atribut penting sebuah laptop tersebut akan dihasilkan masing-masingnya 6 preferensi, jadi secara total akan dihasilkan 42 preferensi yang mungkin muncul dan dilanjutkan dengan membuat daftar hasil dalam bentuk susunan preferensi dan terakhir adalah dibuat matriks berpasangan dalam bentuk rekapitulasi sebelum dilakukan penarikan kesimpulan. Proses penarikan kesimpulan sendiri akan dilakukan dengan menghitung jumlah baris dan bobot yang telah didapat. Jumlah yang paling tinggi (prosentase paling tinggi) merupakan keputusan yang terbaik untuk diambil sebagai solusi. Solusi inilah yang nantinya digunakan untuk membantu para mahasiswa dalam membeli laptop

Abstract

Sistem pakar adalah program komputer dimana program tersebut memiliki pengetahuan seperti layaknya seorang pakar atau ahli. Pada saat ini banyak implementasi sistem pakar di berbagai bidang dan disiplin keilmuan, dimana bidang psikologi menjadi salah satunya. Sistem pakar dalam penelitian ini menggunakan metode Forward Chaining yang berdasarkan pada tes MBTI dalam menentukan kepribadian seseorang, dalam metode MBTI tipe kepribadian seseorang dibagi menjadi 16 tipe kepribadian yang berbeda. Perangkat lunak dalam sistem pakar ini memakai framework CodeIgniter dalam bentuk framework PHP dan model MVC (Model, View, Control) dan menggunakan MySQL sebagai basis penyimpanan pengetahuan. Aplikasi ini dirancang menggunakan Extreme Programming, yang memiliki empat tahapan, yaitu perencanaan, perancangan, pengkodean, dan pengujian. Pengujian aplikasi ini melibatkan pengujian langsung terhadap individu yang menjawab beberapa pertanyaan pilihan ganda untuk mengetahui tipe kepribadiannya. Sistem pakar ini mengumpulkan informasi tentang tipe kepribadian individu tersebut, serta kelebihan dan kelemahan individu tersebut.
