Abstract

Problems in the new student admission process at SMK Negeri 1 Painan are still encountered, one of which is the administrative process that is carried out manually. This causes applicant data management to be less effective, prone to errors, and time-consuming in the selection process up to the announcement stage. In addition, the limitations of the manual system make it difficult for the admission committee to verify documents and prepare reports. Therefore, a web-based information system is needed to manage the processes of registration, selection, journaling, announcement, and re-registration in a more structured, efficient, and accessible manner. The research method used was the Iterative Development method, which is carried out gradually and repeatedly. The research stages consisted of requirements analysis to identify system needs, design to create the interface and workflow, and development to implement the main features such as dashboard, account management, registration form, document verification, announcement of selection results, and reporting.   The results of this study show that system testing using the White Box method obtained an average score of 89.27% in the very valid category. Meanwhile, testing using the Black Box method obtained an average score of 94.86% in the very valid category. The practicality test based on the responses of administrators/admission committees reached 97.22% in the very practical category, while user responses (prospective students) reached 94.5% in the very practical category. The conclusion of this study is that the web-based new student admission system developed with the Laravel framework has been tested valid and practical based on white box and black box testing, as well as user evaluations. Thus, the system is feasible to be used as the main tool in the admission process at SMK Negeri 1 Painan because it improves the effectiveness and efficiency of school administration.

Abstract

The Crime of Human Trafficking is a transnational crime that violates human rights through various forms of exploitation, including sexual exploitation, forced labor, and modern slavery. Although Indonesia has enacted Law Number 21 of 2007 on the Eradication of Human Trafficking, its enforcement still faces numerous challenges, including weak supervision, inadequate victim protection, and the emergence of digital-based trafficking methods. This study aims to analyze the weaknesses of the existing criminal law policy and to formulate a reformed legal policy by positioning human trafficking as an extraordinary crime. Using a normative legal research method, the findings indicate that human trafficking possesses the characteristics of an organized, transnational, and profit-driven crime, thereby requiring special legal treatment. Therefore, it is necessary to strengthen criminal sanctions, optimize asset confiscation, expand corporate criminal liability, and enhance victim protection and recovery mechanisms in order to achieve a more effective and just eradication of human trafficking.

Abstract

This study aims to determine the extent of the influence of work participation, work stress, and compensation on the employee performance of PT. Tidar Kerinci Agung Solok Selatan. The study consists of three independent variables, namely work participation, work stress, and compensation, and one dependent variable, employee performance. The analytical methods employed were correlation analysis and multiple regression analysis. Data were collected through questionnaires completed by employees of PT. Tidar Kerinci Agung Solok Selatan. Furthermore, based on the simultaneous hypothesis test (F-test), the calculated F-value was 19.077, which is greater than the F-table value of 2.76 (19.077 > 2.76), with a significance level of 0.000 (< 0.050). Therefore, it can be concluded that work participation, work stress, and compensation simultaneously have a positive and significant effect on employee performance. In addition, the coefficient of determination (R²) was found to be 0.467, or 46.7%. This indicates that 46.7% of the variation in employee performance can be explained by work participation, work stress, and compensation, while the remaining 53.3% is influenced by other variables not examined in this study.

Abstract

The rapid development of information technology has encouraged schools to implement Academic Information Systems (AIS) to improve the effectiveness of academic data management. However, the quality of information system services is often not optimal, resulting in a gap between users' expectations and perceptions. This study aims to determine the priority areas for improving the quality of the Academic Information System at SMA Negeri 1 Talamau through the integration of the Analytical Hierarchy Process (AHP) and Importance Performance Analysis (IPA) methods. The AHP method is employed to determine the priority weights of each system quality criterion, while IPA is used to identify attributes that require improvement based on their importance and performance levels. The study adopts a quantitative approach involving students, teachers, and administrative staff as respondents. The results indicate that the information quality dimension has the highest priority weight, followed by system quality and service quality. The IPA analysis reveals that several attributes fall into Quadrant I (Concentrate Here), making them the main priorities for improvement, particularly regarding system access speed, academic information accuracy, and service responsiveness. This study produces a priority model that can be utilized by the school as a basis for decision-making in enhancing the quality of its Academic Information System.

Abstract

Abstract: The massive growth of internet penetration in Indonesia has created competitive competition among internet service providers (ISPs), including Biznet Medan. However, the highly diverse and heterogeneous characteristics of customers make one-size-fits-all marketing strategies ineffective and inefficient. Processing large customer data for segmentation is often hampered by the presence of outliers, such as extreme income variations, which can disrupt the clustering accuracy of conventional algorithms. This study aims to optimize the K-Means algorithm in segmenting Biznet Medan's target market to maintain accuracy despite outliers, allowing the company to design more targeted marketing strategies. To overcome K-Means' sensitivity to outliers, this study applies the Robust Scaling technique. This solution uses the Median and Interquartile Range (IQR) values ​​instead of the mean, so that the cluster center points (centroids) remain stable and are not distorted by extreme data values. The research flow includes data collection of prospective Biznet Medan customers, data pre-processing (cleaning and scaling), feature selection (income, distance, and network requirements), and implementation of the K-Means model. Cluster quality evaluation is carried out by comparing the results of using StandardScaler and RobustScaler through the Silhouette Score and Davies Bouldin Index (DBI) metrics. The implementation successfully formed two main segments: Cluster 0 (Enterprise/Premium Customers) with high income characteristics and large bandwidth requirements (>200 Mbps), and Cluster 1 (Casual/Economical Customers) who dominate the market with lower network requirements (<50 Mbps). Optimization with Robust showed significant improvements in the evaluation metrics, where the Silhouette Score increased from 0.3133 to 0.6023, and the DBI value improved from 1.1421 to 0.8007. The implementation of Robust Scaling is effectively able to handle outlier problems in the K-Means algorithm, resulting in a more robust, efficient, and representative cluster structure. These results contribute to the processing of customer data for more objective strategic decision-making in ISP market expansion. Keywords: k-means; clustering; outlier; robust scaling; customer segmentation.   Abstrak: Pertumbuhan internet di Indonesia yang masif telah menciptakan persaingan kompetitif di antara penyedia jasa internet (ISP), termasuk Biznet Medan. Namun, karakteristik pelanggan yang sangat beragam dan bersifat heterogen membuat strategi pemasaran satu untuk semua (one-size-fits-all) menjadi tidak efektif dan tidak efisien. Data calon pelanggan yang besar sering ditemui data yang hilang, perbedaan nilai data yang ekstrim sehingga pengolahan data calon pelanggan untuk segmentasi sering kali terkendala oleh adanya data pencilan (outlier) yang dapat mengganggu akurasi pengelompokan pada algoritma konvensional. Penelitian ini bertujuan untuk mengoptimasi algoritma K-Means dalam melakukan segmentasi target pasar Biznet Medan agar tetap akurat meskipun terdapat data outlier, sehingga perusahaan dapat merancang strategi pemasaran yang lebih tepat sasaran. Untuk mengatasi sensitivitas K-Means terhadap pencilan, penelitian ini menerapkan teknik Robust Scaling. Solusi ini menggunakan nilai Median dan Interquartile Range (IQR) sebagai pengganti rata-rata, sehingga titik pusat klaster (centroid) tetap stabil dan tidak terdistorsi oleh nilai data yang ekstrem. Alur penelitian meliputi pengumpulan data calon pelanggan Biznet Medan, pra-pemrosesan data (pembersihan dan scaling), pemilihan fitur (penghasilan, jarak, dan kebutuhan jaringan), serta implementasi model K-Means. Evaluasi kualitas klaster dilakukan dengan membandingkan hasil penggunaan StandardScaler dan RobustScaler melalui metrik Silhouette Score dan Davies Bouldin Index (DBI). Implementasi berhasil membentuk dua segmen utama: Cluster 0 (Pelanggan Enterprise/Premium) dengan karakteristik penghasilan tinggi dan kebutuhan bandwidth besar (>200 Mbps), serta Cluster 1 (Pelanggan Casual/Hemat) yang mendominasi pasar dengan kebutuhan jaringan lebih rendah (<50 Mbps). Optimasi dengan Robust menunjukkan peningkatan signifikan pada metrik evaluasi, di mana Silhouette Score meningkat dari 0,3133 menjadi 0,6023, dan nilai DBI membaik dari 1,1421 menjadi 0,8007. Penerapan Robust Scaling secara efektif mampu menangani masalah outlier pada algoritma K-Means, menghasilkan struktur klaster yang lebih kuat, efisien, dan representatif. Hasil ini memberikan kontribusi pada pengolahan data pelanggan untuk pengambilan keputusan strategis yang lebih objektif dalam ekspansi pasar ISP. Kata kunci: K-Means; klasterisasi; data pencilan; Robust Scaling; Segmentasi Pelanggan.
