A very important element of railway is the rail bearing, different types of rail bearings that we know in Indonesia are wooden rail bearings, concrete rail bearings. In this study, the stress behavior that occurs in the two types of railway bearings due to the load and the occurring temperature effect is to be checked. It was found that the stress occurring in bearings with different materials, namely concrete and wood, when the The nominal stress can be seen on the concrete bearing is 11.87 N/mm2, on the wooden material the bearing load is 10.41 N/mm2. As for the temperature effect, it looks similar to the temperature of 80 °C for each material, but it can be seen that the temperature effect spreads from the surface due to the friction between the railroad tracks and the railroad wheels.

According to the Minister of Transportation regulation No. 36 article 4, year 2011 concerning the intersection of level crossings, the minimum distance between crossings is 800 meters. However, this regulation has not been well implemented at the level crossings of JPL 297, 295, and 294 at Sukodadi Village, Lamongan Regency. Since the regulations are not implemented yet, hence the accidents frequently occur. Therefore, this study was conducted to find out public perceptions of the planned closure of JPL 297 and 294. This study applied descriptive quantitative method by calculating LHR and vehicle queue lengths. Among the three JPLs, the JPL with the highest LHR was JPL 295 with the total of 249 vehicles per hour. Meanwhile, the longest queue of vehicles occurred at JPL 295 reaching 23 meters. Furthermore, the data were analyzed by using multiple linear regression. The findings claimed that the indicators of benefits involved convenience and safety in 180, 11,506 and 7,781, while the result of the public perception obtained 66.8%.

Prediction of the bearing capacity of deep foundations using analytical methods from the results of the standard Penetration Test has been carried out until now due to practical consideration. However, with the many types of empirical formulas proposed by various researchers, it is necessary to test the validity of the values predicted by the empirical formulas. During the construction stage, the bearing capacity of deep foundations can be checked using the Pile Driving Analysis (PDA) Test. This study aimed to compare the foundation bearing capacity prediction results using analytical methods of Luciano Decourt (1982), Reese and O'Neil (1999), and Building Standard Law of Japan with the results from PDA test. The comparison indicate that the analytical method of Luciano Decourt (1982) predict bearing capacity with the smallest error rate, which is 1.97% to 38.99% with safaty factor (SF) 2 to 3 on a relatively homogeneous and heterogeneous soil conditions. Prediction of bearing capacity of bored pile foundations using analytical methods O'Neil & Reese (1999) and Building Standard Law of Japan provide better performance for soil types which is dominated by cohesive soils with safety factor (SF) 2.

Transportation is the backbone of development. It determines the economic growth of a country. Among any modes of transportation, railway is in need to be developed especially in the increasing of railway lines capacity in addition to the development of railway infrastructures, facilities, and the enhancement of rail operational. The determinant in rail operational is the stability in its operation. This stability can be seen by the punctuality of train arrival and departure, which is in accordance with the Graph Train Journey (Gapeka) and “delay” as the indicator. The study was conducted to determine the stability of railway operation and the delay of train travel as well as to identify the effect of the stability of railway operations to the capacity value of railway line. The study was conducted by collecting secondary data and conducting primary survey followed by data analysis. The results showed that the stability of rail operation for Kroya – Kutoarjo - Yogyakarta line was still low with an average delay of 15.60 minutes for double track and 21.68 minutes for single track. There was a decline in capacity when it was compared to the planned capacity or factual practical capacity at 22% on single track and 17% on double track. Further research on how to determine the cause of the instability of railway operation as input for the stability improvement would be needed in addition to the model or formulation to calculate line capacity in corresponding to the conditions in Indonesia.

In the topology of the DC traction substation there is a rectifier component which generally uses a 12 pulse rectifier type and the load is in the form of a trainset with a component in the form of a converter used for variable speed drives (VSD). The operation of the rectifier and the VSD converter load causes harmonics to appear on the AC input side, so anticipation needs to be done. Therefore, it is necessary to conduct an assessment related to DC traction substations to obtain good electrical power quality. The purpose of this study was to determine the electric power quality parameters of DC railway traction using a 12 pulse rectifier and a VSD converter load. This research was conducted by simulating a DC railway traction model with a 12 pulse rectifier and knowing the comparison of the system power quality between the VSD converter load and the resistive load as the basic reference for the traction substation work system of this model. System modeling is done using PSIM software. The results of the simulation are the parameters of the stability of the voltage, current, and system harmonics.
