Abstract

Penelitian ini mengeksplorasi penerapan algoritma Support Vector Machine (SVM) dalam Text Mining untuk analisis sentimen sektor pariwisata di Indonesia, menggunakan data dari platform Twitter. Data dikumpulkan melalui API Twitter dan diproses melalui tahapan prapemrosesan teks, termasuk tokenisasi, normalisasi, penghapusan stopword, dan stemming, untuk memastikan kesiapan data dalam analisis. Model SVM diuji dengan tiga kernel berbeda—linear, radial basis function (RBF), dan sigmoid—serta menggunakan rasio data latih-uji 7:3 dan 8:2. Hasil menunjukkan bahwa kernel linear dengan rasio 7:3 menghasilkan kinerja terbaik dengan akurasi 92,89%, precision 92%, recall 74%, dan F1-score 81%. Evaluasi berdasarkan kelas sentimen menunjukkan performa tinggi pada sentimen positif (F1-score 96%) tetapi moderat pada kelas netral (F1-score 67%), mencerminkan pengaruh ketidakseimbangan data. Penelitian ini memberikan kontribusi signifikan dalam mendukung pengambilan keputusan berbasis data untuk pengembangan sektor pariwisata. Temuan ini memungkinkan pengelola destinasi wisata untuk memahami opini wisatawan secara otomatis, menyusun strategi promosi yang lebih efektif, serta meningkatkan kualitas layanan. Dengan menerapkan analisis sentimen berbasis SVM, penelitian ini mendukung pengelolaan pariwisata berbasis data untuk meningkatkan daya saing destinasi wisata di Indonesia. Penelitian lanjutan disarankan untuk mengatasi ketidakseimbangan data melalui teknik resampling atau penerapan algoritma alternatif seperti deep learning, guna meningkatkan akurasi klasifikasi sentimen yang lebih kompleks. Dengan demikian, penelitian ini menjadi langkah strategis dalam memanfaatkan teknologi analitik untuk pengelolaan pariwisata yang lebih inovatif.

Abstract

With the rapid advancement of technology, the surrounding environment must adapt to these developments. This can be seen in the industrial sector, which is starting to adopt information systems to support its activities. However, this adaptation is not uniform, and some areas have yet to adopt information systems to support their operations, such as at PT. Diansurya Global, particularly in the General Affairs Division. In this division, all activities are conducted traditionally, such as managing vehicle orders, monitoring the availability of drivers and vehicles, and storing vehicle data, which is still in hardcopy format. Therefore, a monitoring information system is needed to assist the activities in the General Affairs Division. PT. Diansurya Global is a company that produces and exports metal equipment. Consequently, a monitoring information system is designed to provide real-time information on the availability of drivers and vehicles, which accelerates the determination of routes and delivery schedules. Additionally, this system can also assist other divisions in placing operational vehicle orders, thus preventing duplicate or uncommunicated orders due to the documentation within the system. System testing is conducted using the user acceptance testing method to ensure that the features meet user needs. This monitoring information system can also be used to store information such as vehicle administration data, including payment history for administrative costs and maintenance history for operational vehicles.

Abstract

This study aimed to evaluate the quality of the TR Car Dealership web-based sales system by addressing specific challenges in its functionality, reliability, usability, efficiency, maintainability, and portability. The primary objective was to assess whether the system effectively supports user needs and provides a seamless experience for account registration, product browsing, purchase transactions, and administrative tasks. The ISO 9126 model was utilized as the assessment framework, focusing on six quality attributes that are critical to user satisfaction and system performance. Testing was conducted using black-box testing for functionality assessment and survey-based evaluations for usability and user satisfaction. Automated tools, such as JMeter, Google Lighthouse, and SonarQube, were employed to measure reliability, efficiency, and maintainability under various conditions. The results revealed high scores across several attributes: Functionality achieved an average of 90%, affirming the system’s operational capabilities; Usability scored 91.3%, highlighting ease of use; and Efficiency reached 87%, reflecting effective performance under normal load. However, the Reliability attribute scored 86%, indicating room for improvement, particularly in handling high traffic and unexpected inputs. These findings underscore the TR Car Dealership system’s strengths in user-friendliness and feature completeness while suggesting targeted enhancements for reliability and stability. By addressing these aspects, the system can further enhance user trust and deliver a more resilient and consistent performance. This research demonstrates the effectiveness of the ISO 9126 model in identifying actionable improvements for web-based sales systems.
