Abstract

Mangrove crabs (Scylla spp.) are mangrove biota with high ecological and economic value. This study aimed to analyze the community structure of mangrove crabs in Sungai Limau Hamlet, Batu Ampar Village, Kubu Raya Regency. Data were collected from November to December 2025 using the bycatch method from fishermen’s catches using traps. Sampling was conducted four times at one-week intervals. The analysis included relative abundance, diversity (H'), evenness (E), and dominance (C), as well as temperature and salinity. Three species were identified: S. serrata, S. paramamosain, and S. olivacea. Their relative abundances were 88.03%, 10.62%, and 1.34%, respectively. The diversity index was 0.408 (low), evenness was 0.371 (low), and dominance was 0.786 (high). Water temperature ranged from 27–28°C and salinity from 7–10 ppt, with the community dominated by S. serrata and characterized by low diversity.

Abstract

Proses order picking merupakan salah satu aktivitas yang berkontribusi signifikan terhadap biaya dan waktu operasional dalam sistem pergudangan. Kondisi tata letak gudang PT X pada kondisi eksisting belum mempertimbangkan tingkat pergerakan material dan kedekatan lokasi penyimpanan terhadap titik Input/Output (I/O), sehingga menyebabkan jarak tempuh order picking relatif tinggi. Penelitian ini bertujuan untuk menganalisis tata letak gudang PT X dan merancang tata letak usulan menggunakan metode Dedicated Storage dengan Greedy Algorithm guna meminimalkan jarak tempuh dan waktu order picking. Penelitian menggunakan data pergerakan material periode April–Juni 2025 sebagai dasar penentuan prioritas penempatan berdasarkan Turnover to Storage (T/S) Ratio. Metode Dedicated Storage digunakan untuk menentukan kebutuhan dan penempatan ruang penyimpanan berdasarkan tingkat aktivitas material, sedangkan Greedy Algorithm digunakan untuk mengalokasikan material pada slot dengan jarak rectilinear terpendek terhadap titik I/O sesuai urutan prioritas. Evaluasi dilakukan dengan membandingkan jarak tempuh order picking pada tata letak eksisting dan usulan serta mengestimasi perubahan waktu order picking berdasarkan perubahan jarak. Hasil penelitian menunjukkan bahwa tata letak usulan menurunkan total jarak tempuh order picking dari 2.385 meter menjadi 325 meter, atau sebesar 86,38%. Berdasarkan estimasi proporsional terhadap perubahan jarak, rata-rata waktu order picking menurun dari 12,00 menit/siklus menjadi 1,63 menit/siklus. Hasil tersebut menunjukkan bahwa kombinasi metode Dedicated Storage dan Greedy Algorithm dapat menghasilkan tata letak penyimpanan yang lebih terstruktur dan berpotensi meningkatkan efisiensi proses order picking pada gudang PT X.

Abstract

This study aims to analyze the effect of service quality and facility utilization on port operational performance through the implementation process of the ISPS Code at JICT Tanjung Priok. The study integrates the variables of service quality, facility utilization, ISPS Code implementation, and port operational performance, which have been discussed in previous related studies. The survey was conducted using a questionnaire distributed to 186 respondents involved in operational activities at JICT Tanjung Priok. This research employed a quantitative approach using the Structural Equation Modeling (SEM) analysis technique with the assistance of SmartPLS 4.0 software. The results of the study indicate that service quality and facility utilization have a positive and significant effect on both the ISPS Code implementation process and port operational performance. In addition, the ISPS Code implementation process was also proven to have a positive and significant effect on operational performance and to mediate the influence of service quality and facility utilization on port operational performance. The findings reveal that facility utilization has the most dominant influence on the implementation of the ISPS Code, while service quality plays an important role in supporting the effectiveness of port operations. The study concludes that improving service quality, optimizing facility utilization, and strengthening the implementation of the ISPS Code are essential factors in enhancing port operational performance effectively and sustainably. Therefore, port management is recommended to improve service quality, strengthen port security systems, optimize the use of operational facilities, and develop technology-based monitoring and coordination systems to support operational efficiency and port security.
