Abstract

Perkembangan teknologi informasi (TI) yang pesat telah menjadikan TI sebagai faktor penting dalam mendukung operasional dan strategi organisasi, termasuk dalam sektor pemerintahan. Dinas Pariwisata Kabupaten Lombok Tengah memanfaatkan teknologi informasi untuk mengelola promosi digital melalui sistem informasi dan website resmi. Namun, belum optimalnya tata kelola TI serta masih manualnya proses audit menjadi hambatan dalam mendukung efektivitas promosi daerah dan peningkatan pelayanan publik. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan studi kasus pada bidang Promosi & Pemasaran (PP) di Dinas Pariwisata Kabupaten Lombok Tengah. Kerangka kerja yang digunakan adalah COBIT 5, dengan fokus pada tiga domain utama yaitu APO (Align, Plan, and Organize), DSS (Deliver, Service, and Support), dan MEA (Monitor, Evaluate, and Assess). Tujuan penelitian ini adalah mengevaluasi kapabilitas proses tata kelola TI serta memberikan rekomendasi perbaikan. Hasil penelitian menunjukkan bahwa tingkat kapabilitas proses tata kelola TI secara umum berada pada Level 1.3, dengan gap sebesar 1.7 untuk mencapai target Level 3. Dari ketiga domain yang dianalisis, hanya APO01 yang mencapai Level 2, sedangkan DSS03 dan MEA01 masih berada di Level 1. Rekomendasi yang diberikan meliputi penyusunan dokumen kebijakan formal, penerapan sistem pencatatan insiden, pelatihan teknis bagi SDM, serta penguatan kerja sama dengan vendor melalui kontrak dan indikator kinerja. Secara umum, tata kelola TI di Dinas Pariwisata telah berjalan namun belum sepenuhnya terdokumentasi dan distandarisasi. Peningkatan kapabilitas perlu difokuskan pada aspek dokumentasi, monitoring, serta pengembangan kapasitas SDM untuk mencapai tata kelola yang optimal dan berkelanjutan.

Abstract

The System Information Management (SIM) website of Universitas Qamarul Huda Badaruddin BAGU serves as a digital platform designed to support academic and administrative services. This study aims to evaluate the quality of the website by combining functional testing using the Equivalent Partitioning technique and usability assessment through the System Usability Scale (SUS). Functional testing was performed on key features such as the login page, digital library (DILA), user profile, SISKA academic module, and e-money services. The results indicated that the login feature functioned as expected, while several weaknesses were identified in other modules, including the absence of input restrictions in DILA, incomplete validation in profile forms, and insufficient error handling in SISKA and e-money transactions. The usability evaluation involved 80 respondents from various study programs who completed the SUS questionnaire. The analysis yielded an average score of 46.91, corresponding to Grade D, which reflects low usability. While users appreciated the website’s visual appearance and the ease of checking payments via e-money, concerns were raised regarding navigation, error handling, and the effectiveness of learning support features. Overall, the findings suggest that although the MIS website fulfills its basic functions, significant improvements are needed in terms of input validation, interface design, and user experience. This research contributes practical insights for enhancing the reliability and usability of university information systems and provides a foundation for future development aimed at creating more efficient and user-friendly platforms.

Abstract

Perkembangan machine learning mendorong pemanfaatan berbagai model regresi untuk melakukan prediksi data secara akurat dan efisien. Namun, perbedaan karakteristik dataset menyebabkan kinerja setiap model bervariasi, sehingga diperlukan proses benchmarking untuk menentukan model yang paling optimal. Penelitian ini bertujuan untuk membandingkan kinerja beberapa model machine learning dalam tugas prediksi data berbasis regresi tanpa melakukan pengembangan aplikasi. Model yang dievaluasi meliputi Linear Regression, Decision Tree Regression, Random Forest Regression, Support Vector Regression, dan K-Nearest Neighbor Regression. Dataset yang digunakan merupakan dataset publik dengan variabel numerik yang telah melalui tahap praproses data, meliputi pembersihan data, normalisasi, dan pembagian data latih serta data uji. Evaluasi kinerja model dilakukan menggunakan metode K-Fold Cross Validation dengan metrik Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), dan koefisien determinasi (R²). Hasil penelitian menunjukkan bahwa Random Forest Regression memberikan kinerja terbaik dengan nilai error terendah, nilai R² tertinggi, serta stabilitas model yang baik dibandingkan model lainnya. Hasil ini menunjukkan bahwa pendekatan ensemble efektif dalam meningkatkan akurasi dan kemampuan generalisasi model pada tugas prediksi data regresi.

Abstract

Heart failure is a cardiovascular disease with a high mortality rate and tends to increase every year. Therefore, a method is needed that can help the process of classifying heart failure quickly and accurately. This study aims to design and implement a heart failure classification system using the K-Nearest Neighbor (K-NN) machine learning method. The dataset used consists of 918 patient data with eleven input variables and two output classes, namely patients diagnosed with heart failure and patients not diagnosed with heart failure. The research stages include data loading, dividing training data and test data, implementing the K-NN algorithm with various K values, and evaluating model performance using accuracy, precision, recall, and F1-score metrics. The test results show that variations in the K value have a significant effect on the performance of the classification model. The K value = 9 produces the best performance with an accuracy of 93.48%, a recall of 96.36%, and an F1-score of 94.64%, which indicates a good balance between precision and recall. Based on these results, the K-NN method with a value of K = 9 is recommended as the optimal configuration in the classification of heart failure disease in this study.
