Abstract

Internet access is an activity that cannot be separated from the needs of the community, it can be seen from the many activities that use TCP/IP-based internet access. The use of the internet protocol using IPv4 which is currently starting to not meet human needs, it is recommended to be able to implement IPv6 which has a simple header and has a better QoS (Quality of Service). One of these IPv6 is applied to traffic CCTV cameras based on ATCS (Area Traffic Control Security) which works to unify and record traffic activities for 24 hours in the hope that the video streaming results have better network quality.

Abstract

Stroke merupakan penyakit yang berpotensi menyebabkan kelumpuhan bahkan kematian. Pada tahun 2022, stroke terdapat 12,2 juta kasus stroke baru yang menambah jumlah total penderita stroke sebesar 101,4 juta. Dari perolehan data maka diperlukan sebuah teknik yang mampu melakukan deteksi pada penyakit tersebut untuk membantu dalam mendeteksi penyakit stroke, dalam hal ini pendekatan machine learning sebagai salah satu solusi yang dapat digunakan untuk melakukan deteksi pada penyakit stroke. Namun sayangnya data yang diperoleh dalam mendeteki penyakit stroke ditemukan adanya imbalance class dalam menangani tidak imbangnya class sehingga dapat mempengaruhi hasil nilai akurasi dalam mendekteksi penyakit stroke, untuk itu dibutuhkan sebuah algoritma random forest dan metode SMOTE dalam menangani imbalance class. Output yang dihasilkan ialah berupa nilai akurasi, presisi, recall, dan f1-score pada algoritma random forest tanpa SMOTE sebesar 0.98, 0.69, 0.51, dan 0.51. Sedangkan algoritma random forest dengan SMOTE mendapatkan masing-masing sebesar 0.91, 0.92, 0.91, 0.91. Terjadi kenaikan signifikan pada presisi, recall, dan f1-score.

Abstract

This study aims to investigate the effect of product quality on purchase decisions through cash on delivery in the fashion industry. The research was conducted through a survey with 228 respondents who had made purchases through cash on delivery in the past six months. The data was analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS software. The results showed a significant and positive effect of product quality on purchase decisions through cash on delivery in the fashion industry. This finding suggests that consumers who perceive high product quality are more likely to make a purchase decision through cash on delivery in the fashion industry. The study also indicates that the moderating effect of cash on delivery should be considered in future research on the relationship between product quality and purchase decisions in the fashion industry. This study contributes to the existing literature by providing empirical evidence on the effect of product quality on purchase decisions through cash on delivery in the fashion industry. Fashion retailers can use the results to improve their product quality and cash-on-delivery services, potentially increasing consumer purchase decisions and satisfaction.

Abstract

Earthquakes are natural disasters that cannot be prevented or avoided. One of the areas affected is the West Sumatra region, where West Sumatra is one of the regions in Indonesia which is in the Sumatra basin which is vulnerable to earthquakes. Therefore, density-based clustering analysis can be carried out which aims to produce a point map of earthquake-prone areas in the West Sumatra region using the Density Based Spatial Clustering of Application with Noise (DBSCAN) method. In implementing the DBSCAN algorithm, epsilon and minpts parameters are required using the K-Nearest Neighbors method with evaluation of results using the Silhouette Coefficient. The results of DBSCAN clustering using KNN input parameters obtained a total of 3 clusters and 1 noise with a silhouette coefficient value of 0.310 from the 2010-2023 data period. However, from the testing stage without using KNN, we got a high silhouette score, namely 0.890 with 2 clusters and 1 noise.

Abstract

This study examines the impact of tacit knowledge loss due to employee turnover on operational efficiency, innovation capability, and customer satisfaction by examining the mediating role of tacit knowledge loss and the mitigating effect of knowledge transfer effectiveness. Using an explanatory quantitative approach, we collected data through closed-ended questionnaires and secondary data from 200 respondents in the manufacturing, service, and MSME sectors in Bangka Belitung. The Structural Equation Modeling (SEM) analysis results revealed that employee turnover significantly increases tacit knowledge loss, which is detrimental to operational efficiency, innovation, and customer satisfaction. This study also highlights that effective knowledge transfer, especially through structured mentoring programs, reduces the impact of tacit knowledge loss. These findings strengthen the resource-based view and knowledge management theory. In addition, our study shows that integrating CRM technology reduces the impact of tacit knowledge loss on customer satisfaction—a previously unexplored factor. Practical implications include recommendations for HR policies that focus on knowledge retention, collaborative training, and technology adaptation for organizations in the digital era. These findings emphasize the importance of a holistic approach that combines social interactions, knowledge management systems, and local cultural contexts to minimize the risk of brain drain.

Abstract

This study aims to analyze the influence of work-life balance, work stress, and workload on employee performance, with organizational support as a moderation variable. A good work-life balance is expected to improve employee performance, while work stress and high workload tend to lower productivity. Organizational support plays a role in strengthening or weakening the relationship between these variables on employee performance. This study uses a quantitative approach with a survey method involving 183 employees in certain sectors. Data were collected through questionnaires and analyzed using the moderation regression technique. The results of the study show that work-life balance has a positive effect on employee performance, while work stress and workload have a negative effect. In addition, organizational support has been shown to moderate the relationship between work stress and employee performance, as well as between workload and employee performance, by providing a mitigating effect against the negative impact it causes. These findings underscore the importance of organizational policies in creating an optimal work-life balance and providing adequate support to improve overall employee performance

Abstract

This study aims to analyze the influence of organizational culture, work flexibility, and digital competence on work productivity and job satisfaction. The respondents in this study were 200 respondents who were employees working in various industrial sectors in Bangka Belitung who experienced digital transformation in their work environment, Using the path analysis method, the results of the study showed that organizational culture has a positive and significant influence on work productivity and job satisfaction. Work flexibility has also been shown to contribute significantly to Job Satisfaction, showing that the higher the flexibility in the work environment, the more employee satisfaction increases. However, digital competencies do not have a significant relationship with Work Productivity, which indicates that competitive factors in the work environment do not necessarily drive increased productivity. These findings contribute to the development of theories in human resource management by emphasizing the importance of organizational culture and work flexibility in increasing employee productivity and satisfaction. Practically, the results of this research can be a reference for organizations to create a more collaborative and flexible work environment to improve employee welfare and performance. However, this study has limitations in sample coverage and does not consider moderator or mediator variables that can affect the relationship between variables. Therefore, future research is suggested to explore additional factors, such as management support and work-life balance, for a more comprehensive understanding of organizational dynamics and employee productivity.
