Abstract

Tes yang dilakukan dengan menggunakan media komputer disebut ujian berbasis komputer. Pendidikan melaksanakan ujian berbasis komputer untuk mengevaluasi kemampuan peserta didik dan mengukur tingkat prestasi belajar mereka. Pada tingkat pendidikan sekolalah menengah atas, masih ada pelaksanaan ujian yang dilakukan secara tradisional. Sistem ini dimaksudkan untuk mengurangi dampak negatif yang terjadi pada sistem ujian konvesionnal. Langkah-langkah tersebut termasuk mengacak soal untuk setiap siswa guna mengurangi kecurangan dan kolusi antar siswa, serta memungkinkan guru untuk menghindari perhitungan nilai secara manual karena sudah dijalankan oleh sistem. Simpanan ujian disimpan dalam pangkalan data. Observasi langsung dilakukan dalam penelitian ini untuk menganalisis kebutuhan sistem. UML (Unified Modeling Language) dan Flowchart digunakan dalam perancangan sistem ini. Analisis sistem dilakukan menggunakan HTML, CSS, Javascript, Mysql dan PHP, sebagai Database. Pertanyaan dalam platform ini tersaji dalam format esai dan soal pilihan berganda. Pelaksanaan sistem ujian berbasis komputer ini melibatkan fitur bagi admin untuk memperbarui data ujian, materi, ruang kelas, pengajar, dan siswa. Fungsi guru termasuk menambahkan ujian, mendaftar ujian, membuat soal ujian, melihat hasil ujian, dan menganalisis ujian. Bagi murid, fitur yang penting adalah data ujian dan menjawab pertanyaan.

Abstract

Student thesis titles in the Informatics Engineering Department at Stella Maris Sumba University (UNMARIS) have not been grouped optimally based on the student's field of expertise or focus of study. So, the grouping procedure that is important in guiding students must choose a thesis title that is relevant to their field of study. One grouping method that can be used is text mining, which is a part of data mining that is used to identify interesting patterns from lots of data in the form of text. In this research, thesis topics are grouped based on student interest or focus using the Naive Bayes method. Research found that the Naive Bayes algorithm had a 100% accuracy rate in determining the thesis title category. And the accuracy results show that UNMARIS students are more interested in choosing titles in the Software Engineering and Expert and Decision System categories, which shows 31 interested in RPL and 36 in Expert Decision Systems.

Abstract

Timely graduation itself is one of the indicators of the success of students' academic performance. The study period regulations are already set in the provisions of the Minister of Education and Culture of Indonesia. To address this issue, there needs to be a technique to predict graduation. One of the techniques commonly used is data mining. In this study, the authors will compare two data mining methods, namely Naive Bayes Classifier and Decision Tree, to obtain the method with the best accuracy in predicting student graduation. The attributes used for Data Mining Classification consist of 10 attributes: Student ID, Gender, Student Status, Age, Semester 1 Grade Point Average, Semester 2 Grade Point Average, Semester 3 Grade Point Average, Semester 4 Grade Point Average, Cumulative Grade Point Average, and Result attribute. From the test results using RapidMiner tools with two methods that have been conducted, the Decision Tree (C4.5) obtained the accuracy result of 70.18%, and the Naïve Bayes method obtained the highest accuracy result of 71.24%.

Abstract

Wisatawan ketika sedang berlibur ke suatu kota, tentu akan memesan akomodasi di hotel. Pengunjung sering kesulitan memilih hotel ketika memesan penginapan karena banyaknya pilihan. Tripadvisior adalah sebuah platform pemesanan hotel yang memberikan fitur-fitur lengkap untuk membantu pengunjung dalam memilih hotel yang tepat. Salah satu fitur yang disediakan adalah ulasan yang menunjukkan komentar-komentar dari para pengunjung mengenai hotel tersebut. Tetapi, semakin banyak saran atau tinjauan mengenai suatu hotel akan membuat pengunjung butuh waktu lebih lama untuk memilih hotel yang mereka inginkan. Dengan permasalahan tersebut, diperlukan analisis sentimen yang dapat mengambil beberapa komentar untuk mendapatkan informasi yang berguna bagi pengunjung. The sentiment analysis system that was developed aims to create a sentiment model to evaluate comments and reviews of a hotel. Analisis sentimen diproses dengan menggunakan Naive Bayes Classifier algorithm. Pengujian menunjukkan bahwa pengklasifikasian sentiment dengan menggunakan Naïve Bayes Classifier mencapai tingkat keakuratan sebesar 90.71%.

Abstract

SMP Negeri 2 Wanukaka is one of the educational institutions in West Sumba Regency. The purpose of designing and implementing this web-based new student registration information system is due to the lack of information to prospective new students regarding information on the new student registration process such as registration flow, information on registration fees and so on. So by designing this information system prospective new students can access new student registration information online so that prospective new students do not have to go to school to get registration information. In designing this web-based new student registration information system using the PHP and MySQL programming languages as database servers which have been summarized in one XAMMP application, the system design uses the waterfall method which consists of analysis, system design, coding and testing. The aim of creating this system is to support the service process so that it can improve the quality of service in conveying information to the public and assist the school in processing data on prospective new students well. After implementing the system and user testing which was carried out using the interview method at the school, the results were obtained that the existence of this web-based new student registration information system can help prospective new students to receive and access online registration information, including information on registration requirements. , test schedule, registration fees, graduation announcements, as well as a test card feature that can be printed directly by prospective new students which will later be used as a requirement for taking the selection exam. It can also help the school in preparing new student reports online, so that the information provided is distributed more effectively and efficiently, and the processing of new student admissions data can be done more effectively.
