Abstract

The Capacitated Vehicle Routing Problem (CVRP) presents significant challenges in shipping route optimization and logistics management. These challenges include balancing vehicle capacity, minimizing travel distance, and efficiently grouping delivery points, all of which are crucial for enhancing operational efficiency and reducing costs. This research aims to apply a combination of the Sweep and Nearest Neighbor algorithms to address the CVRP, seeking to improve route efficiency and manage vehicle capacity effectively. The Sweep algorithm is employed to cluster pickup points based on their polar angle from the depot, facilitating efficient grouping and optimal vehicle capacity management. Within each cluster, the Nearest Neighbor algorithm is implemented to optimize the sequence of visits, minimizing total travel distance by sequentially selecting the next closest point. The Haversine Distance is used to calculate the distances between points, ensuring geographical accuracy compared to the Euclidean method. Experimental results demonstrate that this hybrid approach yields shorter routes. Quantitative analysis shows a significant reduction 13% in total travel distance when using this combination of algorithms, highlighting its effectiveness in solving the CVRP. This research demonstrates that combining the Sweep and Nearest Neighbor algorithms provides an efficient solution to the CVRP, improving route optimization and vehicle capacity management. The findings contribute valuable insights to logistics management, with practical implications for enhancing shipping route efficiency.

Abstract

Penelitian ini membahas analisis penyebab kecelakaan kerja di tambang batu bara Sawahlunto dengan memanfaatkan metode Job Safety Analysis (JSA) dan Fault Tree Analysis (FTA). Pendekatan JSA dimanfaatkan untuk mendeteksi potensi risiko pada enam tahap aktivitas penting seperti pemasangan penyangga tambang dan pemeriksaan geologi, sedangkan FTA digunakan untuk memetakan hubungan sebab-akibat secara sistematis sehingga akar penyebab kecelakaan dapat teridentifikasi dengan jelas. Hasil penelitian menunjukkan bahwa kecelakaan kerja di tambang bukan hanya disebabkan oleh satu faktor, melainkan gabungan dari kegagalan teknis dan lemahnya aspek manajemen, seperti kegagalan struktur tambang, tidak berfungsinya sistem peringatan dini, serta kurangnya pengawasan K3 di lapangan. Temuan ini menunjukkan pentingnya penerapan pemantauan geoteknik secara berkala, pemasangan sensor tanah dan alarm peringatan, penerapan SOP yang konsisten, serta pelatihan keselamatan untuk pekerja tambang. Rekomendasi dari penelitian ini diharapkan dapat membantu menciptakan budaya keselamatan kerja yang baik serta mendukung upaya zero accident di sektor pertambangan. Penelitian ini juga diharapkan menjadi referensi dalam perbaikan sistem K3 dan mendukung transformasi pertambangan berbasis teknologi untuk meminimalkan risiko kecelakaan secara berkelanjutan.

Abstract

This community service activity aims to explore the challenges faced by managerial level career women in managing time between work and domestic obligations. The method used was Focus Group Discussion (FGD) involving 25 female participants who served as general managers, middle managers, and HRD practitioners from domestic and multinational companies in the Ngoro Industrial Park (NIP) industrial area, Mojokerto. The discussion was directed at identifying constraints in time management, strategies for dealing with multiple roles, and formulating policy recommendations that support work-life balance. The results of the discussion showed that participants faced high mental stress due to long working hours, social expectations as wives/mothers, and lack of institutional support. These findings reinforce the results of previous studies on mental burden, role inequality, and the dominant masculine work culture. The resulting recommendations include the development of flexible work policies, equal division of labor, gender-sensitive internal mentoring, and institutional support such as counseling and childcare services. This activity is expected to encourage the development of more gender-responsive company policies and strengthen the sustainability of women's leadership roles in the industrial sector.

Abstract

The manufacturing sector in Indonesia plays a vital role in the economy, and one of the critical aspects of enhancing productivity is minimizing machine downtime. PT. Sinar Indo Green Kencana (SIGK) is a building materials manufacturing company facing challenges in the efficiency of its mixer machine, with an Overall Equipment Effectiveness (OEE) value of only 77.5%. This study utilizes Internet of Things (IoT) technology to monitor machine conditions in real-time and assess machine effectiveness using the OEE method. The research aims to identify the primary causes of downtime and develop predictive maintenance strategies to reduce losses due to machine failures. The findings reveal that high downtime is caused by unexpected breakdowns, lengthy setup times, and a lack of real-time monitoring. Therefore, using IoT to monitor downtime and OEE is crucial for improving machine efficiency and maintaining product quality. The research provides improvement recommendations that can be applied to enhance production effectiveness and minimize losses due to machine downtime.

Abstract

This study examines how employees in manufacturing and service firms interpret Corporate Social Responsibility (CSR) and Sustainable Development in their organizational context. The study is motivated by the continuing debate on whether CSR and Sustainable Development are understood as identical, different, or overlapping concepts in business practice. A descriptive qualitative approach was employed. Data were collected through semi-structured interviews with 11 employees working in manufacturing, service, and construction-related service contexts in East Java, Indonesia. The data were analyzed using descriptive thematic analysis, including data reduction, coding, categorization, interpretation, and conclusion drawing. The findings show that employees interpret CSR and Sustainable Development in different ways. Some employees understand CSR mainly as charity or social donation. Others interpret CSR as part of Sustainable Development, especially when company programs are related to environmental preservation, education, health, and community empowerment. The study also finds that internal communication and employee involvement play important roles in shaping employees’ understanding of the relationship between CSR and Sustainable Development. These findings imply that companies need not only to implement CSR programs, but also to communicate them clearly and align them with long-term sustainability objectives so that employees can understand and support them as internal stakeholders.
