Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh jumlah kapal tunda, approach time, postpone time, effective time, berth time dan turn round time terhadap kesiapan operasi peralatan di Pelabuhan Cigading secara parsial dan simultan. Metode penelitian menggunakan metode kuantitatif. Desain penelitian menggunakan desain kausal. Populasi penelitian adalah kapal curah kering sebanyak 37 kapal, teknik sampling menggunakan sampling jenuh. Jenis data adalah data kuantitatif, dan sumber data adalah data sekunder. Analisis data menggunakan analisis regresi linear berganda. Berdasarkan hasil pengolahan data, diketahui nilai R Square sebesar 0,529 yang menunjukkan besarnya variasi kesiapan operasi peralatan dapat dijelaskan oleh variabel jumlah kapal tunda bekerja, waktu kapal tunda bekerja atau approach time, waktu pengurusan dokumen, effective time, berth time dan turn round time secara simultan sebesar 52,9%.

Abstract

The Singkil Adiwerna intersection in Tegal Regency with a 2-phase arrangement has the potential to cause accident risks due to traffic conflicts. For this reason, it is necessary to make efforts to arrange phases to reduce traffic conflicts aimed at improving traffic safety by considering intersection performance. The analysis method uses PKJI (2023) method for intersection performance, PTV VISSIM for simulation modeling, and Surrogate Safety Assement Model Software for the number of conflicts. The results of the analysis of 2-phase conditions with a cycle time of 86 seconds have a degree of saturation of 0.60, a queue of 7.09 meters, a delay of 16.72 seconds, an intersection level of service B and a safety level with a conflict value of 452. The application of 3 phases with a cycle time of 100 seconds has a degree of saturation of 1.01, a queue of 14.02 meters, a delay of 32.74 seconds, an intersection level of service C, and a conflict value of 243 with a 46% decrease in conflict value from 2-phase conditions. If the application of 4 phases with a cycle time of 130 seconds has a degree of saturation of 1.27, a queue of 20 meters, a delay of 47.73 seconds, an intersection level of service D, and a conflict value of 104 with a 77% decrease in conflict value from the 2-phase condition. Based on PM 96 of the Ministry of Transportation, judging from the function of the road, namely a secondary collector road with a level of service of at least C, the selection of phase settings and cycle time of the APILL intersection recommends 3 phases with a cycle time of 100 seconds.

Abstract

With the provision of feeder mode (Feeder) train, which consists of Feeder Train and Commuter Line Bandung Raya, it will provide several alternatives for passengers who will continue their trip to the center of Bandung City. Under existing conditions, the Feeder Train experienced a significant increase in interest compared to the Commuter Line Bandung so that there is a gap in the probability of Feeder Train passengers with Commuter Line Bandung Raya. This is what makes researchers feel the need to analyze passengers' preferences in choosing the next mode of transportation and get an understanding of what factors influence the choice of transportation and sensitivity to the model. The number of samples from this study amounted to 96 respondents with data analysis methods using logistic regression analysis and binary logit difference analysis. Based on the results of logistic regression analysis, the following difference utility function model is obtained: PFeeder = 1/(1+ e^(-(0.442 + (X1) + 0.122 (X2) + 0.023 (X3) + 0.020 (X4) + (X5))) with PFeeder = Probability of Feeder Train, PCL = Probability of Comline Baraya, X1 = cost, X2 = frequency, X3 = travel time, X4 = headway, X5 = capacity. From the model, a higher probability of choosing Feeder Train is obtained with a probability value of 61% and the probability value of Commuter Line Bandung Raya is 39%. In other words, respondents still tend to choose Feeder Train to be used as a further mode of transportation, with influencing factors based on test results with high significance, namely cost, time and headway. From the results of the sensitivity analysis of the cost, travel time and headway variables, the cost variable is the most sensitive variable if there is a change in value on the attribute compared to the travel time and headway variables.

Abstract

Road pavement deterioration reduces transportation safety, ride quality, and operational efficiency, making systematic condition assessment essential for maintenance planning. This study evaluates pavement condition along Jalan Datuk Setia Maharaja, Pekanbaru using the Pavement Condition Index (PCI) method, identifies dominant distresses, and recommends segment-level maintenance strategies. A quantitative descriptive approach analyzed secondary survey data from eight segments covering approximately 1.62 km, applying standardized PCI procedures based on Total Deduct Value and Corrected Deduct Value, with maintenance priority determined through a Priority Score calculated as 100 − PCI. Results show an average PCI of 53.5, indicating overall Fair condition, with individual values ranging from 40 to 76. Segments 1 and 5 recorded the lowest PCI values and highest priority scores, requiring urgent intervention, while Segment 3 needed only routine maintenance. Among 225 identified distress occurrences across fourteen categories, patching dominated at 33.78%, followed by potholes (16.00%), longitudinal cracking (14.22%), and ravelling (13.33%), indicating recurring localized repairs and continuing structural deterioration. The study concludes that integrating PCI with Priority Score and distress analysis enhances maintenance decision-making and resource allocation. Future research should incorporate traffic loading, drainage, and environmental factors to develop predictive pavement management models.
