Abstract

This study presents a comprehensive exploratory data analysis (EDA) of transaction data within the Transjakarta public transportation system, focusing on routes, passenger flow, and congestion patterns. Leveraging tap-in and tap-out transaction records collected through payment cards, the research aims to provide actionable insights for optimizing operational efficiency and enhancing service quality. By analyzing transaction data, the study identifies busy routes, peak hours, and passenger distribution across different modes of transportation, including big bus (BRT), medium and big bus (non-BRT), and mini-bus (Mikrotrans). Moreover, the research investigates correlations between transaction volume and traffic congestion levels, enabling the identification of areas prone to delays and bottlenecks. The findings of this analysis offer valuable information for route planning, scheduling adjustments, and infrastructure improvements within the Transjakarta system. By optimizing resources based on data-driven insights, the study seeks to contribute to the enhancement of public transportation services, promoting accessibility, reliability, and sustainability in urban mobility.

Abstract

Tanjung Kalian Crossing Port is a port located in West Bangka Regency, Bangka Belitung Islands Province. The crossing transportation service at the Tanjung Kalian Crossing Port is one of the prima donnas for service users because this port is the gateway in and out to South Sumatra Province where it has 14 ships with 9 ships operating every day. The load factor at the Tanjung Kalian Crossing Port has currently reached the maximum limit. However, the operation of ships on this track is not in accordance with the minimum service standards for ship operation and the ideal departure frequency. In order to improve the quality of service and the safety of service users, it is necessary to balance the needs of service users and transportation service providers. The methods used in this study are load factor analysis, analysis of conformity with minimum service standards for ship operation, analysis of ship needs, and scheduling analysis. Based on the results of the analysis of the load factor calculation, it shows that the load factor exceeds the ideal capacity of the ship. The minimum service standards for ship operations have also not been met because the ship's departure time and the average speed of the regular ship are not in accordance with the existing rules. There is a difference in Existing conditions with the results of the analysis of ship needs and optimal ship scheduling so that it is necessary to reschedule according to the needs of service users.

Abstract

Keterbatasan pasokan energi listrik di daerah pedesaan yang bergantung pada transportasi air menuntut solusi inovatif berbasis energi terbarukan. Penelitian ini bertujuan untuk merancang dan mengimplementasikan Pembangkit Listrik Tenaga Surya (PLTS) pada kapal penyeberangan di Dermaga Desa Sukarela, Kecamatan Rantau Bayur, Kabupaten Banyuasin. Metodologi penelitian meliputi studi literatur, survei lapangan, perancangan sistem, implementasi perangkat keras, dan pengujian kinerja sistem. Sistem PLTS menggunakan panel surya berkapasitas 300 Wp dengan dukungan solar charge controller dan baterai penyimpanan energi untuk menyuplai kebutuhan listrik kapal dan dermaga. Hasil pengujian menunjukkan bahwa potensi produksi energi listrik tahunan mencapai 1.381,2 kWh, dengan produksi energi tertinggi sebesar 295 W pada pukul 11.00 WIB, dan terendah sebesar 130,5 W pada pukul 16.00 WIB. Sistem PLTS terbukti dapat bekerja dengan baik dalam mendukung operasional kapal penyeberangan sekaligus mengurangi ketergantungan terhadap bahan bakar fosil. Implementasi sistem ini tidak hanya berdampak pada efisiensi biaya operasional, tetapi juga mendukung kebijakan nasional terkait transisi energi dan pemanfaatan energi terbarukan pada sektor transportasi.

Abstract

The Merak Ferry Port is a major ferry transportation route in Indonesia, serving the Merak-Bakauheni crossing. Based on observations and analysis, several issues were identified related to the zoning system and vehicle traffic flow patterns in 2023, such as the combination of executive and regular vehicle lanes in a single service, limited parking capacity, and the presence of crossings between vehicles that hamper the smooth loading and unloading process. This study aims to analyze and compare the zoning system and traffic flow patterns at the Merak Ferry Port in 2023 and 2025 to evaluate the effectiveness of the changes made. This study employed a qualitative descriptive method, with data collection techniques through field observation and analysis of official documents. The results indicate that changes to the 2025 zoning system, including the separation of executive and regular vehicle lanes and the addition of ready-to-load parking capacity, have a positive impact on the smooth flow of vehicles and the effectiveness of space management. Overall, these zoning changes have successfully improved the existing system and increased operational efficiency and service quality at the Merak Ferry Port.

Abstract

Sampalan Ferry Port serves the Sampalan-Sanur and Sampalan-Kusamba routes. From the results of a field survey based on the regulation of the Director General of Land Transportation Number KP-DRJD 6188 of 2024 concerning Guidelines for Assessment and Supervision of the Implementation of Ferry Port Service Standards, it was found that several services for service users had not been implemented properly, such as temperature control facilities, parking area instructions, CCTV that could not see the entire vehicle parking area, gangways and evacuation assembly points. As well as the unavailability of zoning signs A1, A2, A3, evacuation route instructions, information on further transportation, first aid kits, health clinics/posts and breastfeeding rooms. This study used the Customer Satisfaction Index (CSI) method to determine the index of service user satisfaction with passenger services, and the mapping of the Importance Performance Analysis (IPA) quadrant to determine the priority scale of service attributes according to the interests of service users. Based on the analysis using the CSI method, the service user satisfaction index was 70.38%, and this criterion was categorized as satisfied. Based on the IPA quadrant mapping analysis, the attribute in quadrant I, which is the top priority for improvement, is the temperature control facility in the terminal building.
