Abstract

This study aims to explore the challenges faced by students of the Statistics Study Program at Universitas Negeri Medan in the process of writing scientific articles. Previous research has shown that these difficulties are related to motivation, time, and access to references. The method applied in this study is a survey using a questionnaire. The findings indicate the importance of enhancing academic guidance, training in scientific writing, and utilizing technology to support the writing process. The conclusion emphasizes that support from academic institutions is essential in helping students overcome these difficulties, enabling them to produce scientific articles that meet the expected academic standards.

Abstract

A problem that often arises is the lack of a clear system for categorizing and classifying tourist attractions based on geographical characteristics. Tourist route planning, supporting infrastructure development, and targeted promotion strategies all become more difficult because of this. As a result, a data-driven approach is needed to more systematically analyze and map tourist attractions in Deli Serdang Regency. This research aims to map and cluster tourist attractions in Deli Serdang Regency based on spatial characteristics and entrance ticket prices using the K-Means Clustering method. This method is used to group tourist sites into several categories based on the similarity of attributes, which include geographic coordinates (latitude and longitude), ticket prices, and distance to the city center as a reference location. The data were analyzed using a spatial statistics approach using Python, while spatial visualization of the clustering results was done with the help of QGIS software to facilitate interpretation of the area. The results of the analysis show that tourist attractions in Deli Serdang Regency can be grouped into three main clusters, each representing tourist groups that are very close, close, and far from the city center, and have differences in the range of admission prices. Evaluation of cluster quality using the Davies-Bouldin Index (DBI) resulted in a value of 1.377, which indicates that cluster formation has been quite good, although there is room for improvement. Thus, this study succeeded in mapping and clustering tourist attractions in Deli Serdang spatially using the K-Means Clustering approach, which is expected to contribute to tourism promotion planning and tourist destination development in the region.

Abstract

Pembangunan manusia adalah aspek fundamental dalam kemajuan suatu negara, dan Indeks Pembangunan Manusia (IPM) menjadi indicator Utama untuk mengukur kesejahteraan masyarakat. Penelitian ini bertujuan untuk menganalisis pengaruh Produk Domestik Regional Bruto (PDRB) per kapita, umur harapan hidup (UHH), dan harapan lama sekolah (HLS) terhadap IPM di Provinsi Sulawesi Utara. Menggunakan pendekatan kuantitatif dengan model regresi linier berganda, penelitian ini melibatkan data sekunder dari Badan Pusat Statistik untuk 15 kabupaten/kota selama periode 2020 hingga 2024. Hasil analisis menunjukkan bahwa semua variable independent secara signifikan mempengaruhi IPM, baik secara parsial maupun simultan. Model regresi awal yang hanya menggunakan PDRB memiliki kemampuan terbatas dalam menjelaskan variasi IPM, sementara penambahan UHH dan HLS secara signifikan meningkatkan kinerja model. Transformasi logaritmik diterapkan untuk memperbaiki spesifikasi model, dan hasilnya menunjukkan bahwa model log-log adalah yang paling efisien dengan nilai Adjusted R² sebesar 0,955 dan AIC terendah. Kesimpulannya, PDRB, UHH, dan HLS memiliki peran penting dalam pembangunan manusia di Sulawesi Utara. Penelitian ini merekomendasikan penambahan variable lain dan pengembangan model prediktif untuk penelitian selanjutnya guna meningkatkan akurasi dan daya jelaskan model terhadap IPM.
