Abstract

The demand for goods delivery services is increasing along with the widespread use of e-commerce platforms for buying and selling. One of the popular and frequently used delivery service providers is J&T Express. Until now, J&T has had a wide service coverage. However, various customers also have complaints that are often conveyed through social media X. For this reason, this study conducted a sentiment analysis of J&T Express user opinions on social media X using the Naïve Bayes Classifier (NBC) and K-Nearest Neighbor (KNN) algorithms. Data collection was carried out through scraping over a time span from January 1, 2023 to December 1, 2024, resulting in a total of 1,000 data points. The modeling results show that the NBC algorithm outperforms KNN, achieving an accuracy of 72.30%, a precision of 74.76%, and a recall of 72.30%. Meanwhile, the KNN algorithm with the best parameters (K = 9) only has an accuracy of 67.29%, precision of 69.46%, and recall of 67.29%. Then the results of the analysis show that J&T user opinions are dominated by negative sentiment (42.20%), followed by positive sentiment (38.70%) and neutral sentiment (19.10%). Further analysis based on five variables was also conducted and an understanding of J&T's weaknesses, namely in the service aspect, with the highest negative sentiment (21.0%). On the other hand, the user experience aspect is an advantage with the most positive sentiment (16.8%). The data visualization results also indicate that there are dominant customer complaints about the delay in the delivery process. However, customers also appreciate the speed and security of the delivery of goods. These findings provide valuable insights for J&T Express to conduct evaluations and improvements, especially in the service aspect, to improve overall customer satisfaction and experience.

Abstract

Inter-regional socio-economic disparity remains a persistent challenge in regional development across Indonesia, including Riau Province. Differences in economic capacity, human development quality, poverty levels, and labor absorption indicate that development characteristics across regencies and cities are not yet uniform. This study aims to classify regencies and cities in Riau Province based on socio-economic indicators for the 2019–2023 period using K-Means and Hierarchical Clustering algorithms, as well as to compare the most suitable method for representing the data structure. Secondary data utilized in this study consist of five main macro-indicators: Gross Regional Domestic Product (GRDP) per capita, poverty rate, open unemployment rate, Human Development Index (HDI), and mean years of schooling. The research stages involve data preprocessing, Min-Max normalization, outlier detection, clustering algorithm implementation, and evaluation using the Silhouette Coefficient, Davies-Bouldin Index, and Calinski-Harabasz Score. The results demonstrate that the optimal number of clusters is two, where both algorithms yield identical evaluation values: a Silhouette Coefficient of 0.55, a Calinski-Harabasz Score of 34.45, and a Davies-Bouldin Index of 0.47. The clustering results reveal that Pekanbaru City forms a distinct, solitary cluster due to its superior macro-indicators, while the other eleven regencies and cities are grouped into the same cluster. This finding confirms a sharp socio-economic division between the provincial capital and its peripheral regions, which can simultaneously be utilized by the regional government as an empirical baseline evaluation to accelerate the achievement of SDGs Goal 1, Goal 4, and Goal 8 targets at the local level.

Abstract

Penelitian ini bertujuan untuk mengevaluasi efisiensi berbagai struktur data yang tersedia dalam bahasa pemrograman Python, khususnya dalam konteks operasi pencarian (searching) dan penyimpanan (storing). Struktur data seperti list, tuple, set, dan dictionary memiliki karakteristik dan kompleksitas waktu yang berbeda, sehingga pemilihan yang tepat sangat berpengaruh terhadap performa program, terutama pada skenario dengan data berukuran besar. Metodologi penelitian ini menggunakan pendekatan kuantitatif melalui serangkaian pengujian eksperimental terhadap masing-masing struktur data. Pengujian dilakukan dengan mengukur waktu eksekusi dan penggunaan memori dalam operasi pencarian dan penyimpanan terhadap sejumlah data dengan variasi ukuran dari kecil hingga sangat besar. Hasil pengujian menunjukkan bahwa dictionary memiliki performa terbaik dalam hal kecepatan pencarian dan penyimpanan karena memanfaatkan teknik hashing, sementara set juga menunjukkan efisiensi yang tinggi dalam pencarian tetapi lebih terbatas dalam hal penyimpanan data kompleks. Sebaliknya, list dan tuple menunjukkan efisiensi yang lebih rendah dalam pencarian karena memerlukan pencarian linear, meskipun penggunaan memori tuple lebih hemat dibanding list. Kesimpulan dari penelitian ini menekankan pentingnya pemahaman terhadap karakteristik struktur data dalam Python untuk mengoptimalkan efisiensi program, khususnya dalam sistem atau aplikasi yang mengandalkan pemrosesan data dalam jumlah besar. Implikasi dari studi ini dapat digunakan sebagai acuan bagi pengembang perangkat lunak dalam memilih struktur data yang paling sesuai berdasarkan kebutuhan spesifik dari aplikasi yang dikembangkan.
