Abstract: The research aimed to determine exhaust emission and speed of the truck when moving. Measurements were made using a mobile emission analyzer that absorbed emission from truck exhaust. Data collection was done by putting mobile emission analyzer on the right side of the vehicle which absorbs 5 emissions of approximately 5 minutes. The relationship of exhaust emission and speed uses the polynomial model of the average value of exhaust emission and speed. The reliability of mobile emission analyzer uses the multiplier factor to solve the data difference between mobile emission analyzer and Bosowa equipment. The results of research indicate emission of CO 2 , NOx, Smoke, CO, and HC forming driving cycle pattern. This pattern shows the pattern follows parabola tendency. Emission on damaged road is higher than good road although the emission values are not much different. However, the value of emission of Smoke is relatively equal in both road conditions.

Abstract: The Port of Jayapura is located in Papua Province, including the Second Class Port within the Working Area of Indonesian Port IV, located between 02º 32º 30º LS and 140º 42º 30ºBT. The position of Port of Jayapura is strategic and part of the sea toll road in Indonesia, as it faces the Pacific Ocean in the north. Areas have potential as hinterland harbour Jayapura. Almost all of the district needs logistics in the central mountains of Papua, which are served by the Port of Jayapura. Distribution patterns are long enough to cause the cost component on behalf of transportation components can reach Rp 1.1 million per sack of cement or the price can rise to 1200%. The means have a significant effect on the port’s performance of 35.8%, meaning that every 100% increase in facilities will increase port performance by 35.8%. Infrastructure significantly affects the port’s performance of 42.6%, meaning that every 100% increase in infrastructure will increase the port’s performance by 42.6%. The Ulayat right has significant effect on the material of 38.9% with the negative direction that the increasing customary rights of the indigenous people will decrease the port performance. The increase of Ulayat rights by 100% will decrease the port’s performance by 38.9%.

Abstract: This study aims to analyze the compressive strength value of Senoni stone, East Kalimantan and its effect on water immersion. Free compressive strength testing is carried out at 25oC. The number of cylindrical and cube specimens for free compressive strength test each of 3 specimens. Compressive strength testing using the Universal Testing Machine (UTM). The results showed that the compressive strength of Senoni stones decreased due to water immersion. This shows that the stone of Senoni, East Kalimantan is not resistant to water.

Abstract: Previous studies found that delay at signalized intersection accounted for more than one-third of total travel time. Different level of services tends to have different delay probability. An early assumption was made that multimodality occurs because of two traffic states experienced by the traveler delay and non-delay at the signalized intersection. This study proposed a method to quantify delay distribution at a signalized intersection by analyzing the patterns in the speed time and speed distance profiles when passing two consecutive intersections and redrawing vehicle trajectory generated by ‘second by second’ GPS data. The searching algorithm was developed to search for the times when the vehicle enters and leaves the delay section by checking the ‘second by second’ speed data. To differentiate between the queue, move up and stop and go traffic, the algorithm searches for the idle time (i.e. when the speed less than 3.5 km/h). Along with Sydney Coordinates, Adaptive Traffic Systems (SCATS) degree of saturation and signal settings (green and red time) generating from SCATS systems at upstream loop detectors, a realistic delay probability model also was developed. This model used the General Additive Model for Location, Shape, and Scale (GAMLSS) which allows location, scale and shape parameter of selected distribution as a function of the explanatory variable. Signal settings and SCATS degrees of saturation were used as an explanatory variable. This model enables us to estimate delay experiencing by traveler depending on traffic parameters including traffic flow, signal settings and degree of saturation that are readily available on the site.

Abstract: The purpose of this study was to examine the relationship between vehicle distance (gap) formed by the vehicle volume. For this reason, in this study, there were 16 (sixteen) roads that were used as objects of research. To get the values from the gap variable, the VISSIM software is used in the data processing. In the use of this software calibration and validation are done by trial and error to produce simulation results that can replicate the actual traffic conditions. The results of this study indicate that statistically from the coefficient of determination and F test conducted concluded that there is a significant relationship between vehicle volume and gap.
