Abstract

The Trans Seram road section of Lumoli Village, West Seram Regency has a length of 7,150m and a width of 6m starting from STA 0+000 to STA 7+150. Along the road section there are four landslide points, namely at STA 0+350, STA 1+850, STA 2+600 and STA 3+615. Of the four avalanche points, there are three points that have been handled and the remaining one point has not been handled. The avalanche problem at STA 3+615 - STA 3+650 occurs along 35m with a slope height of 6m already covering the road body ± 4.2m remaining 1.8m. This greatly disrupts the activities of road users because it causes narrowing of the road body and temporary avalanche handling using used asphalt dromes. The purpose of this research is to determine the dimensions and stability of retaining walls against shear, overturning and soil bearing capacity on the Lumoli village trans seram road section. The planning of retaining walls on the trans seram road section of Lumoli village uses a cantilever type with a height of no more than 6-7m as a structure to prevent soil collapse by using rankine theory to calculate lateral soil pressure. The results of the dimensions of the cantilever type retaining wall H = 4m, H1 = 3.52m, H2 = 0.48m, Df = 0.8m, H2 = 16m, H22 = 0.23m, A = 0.66, b = 0.3m, C = 1.18m, D = 0.66m, B = 2.8m. And the results of stability against overturning = 3.027 ≥1.5 Safe, stability against shear = 2.910 ≥1.5 Safe and stability against bearing capacity = 809.045 Kn/m2.

Abstract

This research aims to plan the thickness of flexible pavement layers on road segments that have not been coated with pavement on the Laha-Negeri Lima road section, Central Maluku Regency. Through primary data collection, namely data obtained in the field including DCP, LHR survey, road dimensions, and documentation. While secondary data is data obtained from agencies, such as Ambon Island road maps, including field observations, interviews, and literature searches, and analysis using the 2017 Road Pavement Design Manual Method. This research determines the appropriate thickness of flexible pavement layers to facilitate inter-regional connectivity and increase local economic potential. The results of the analysis show that the thickness of the asphalt layer is adjusted to the Road Asphalt Plan Manual No.02/M/BM/2017 and the thickness of the flexible pavement layer on the Laha Village - Negeri Lima Village connecting road section along 3000 m is obtained AC WC 4 cm, AC BC 6 cm, AC BASE 7 m, and LFA Class A 30 cm. While the cumulative value of the standard load with a planning length of 3000 m and a width of 6 m is obtained in total 3,252,548 and an average CBR value of 8.17%.

Abstract

Waitunsa Bridge is located in Siwalalat subdistrict, Eastern Seram Regency Siwalalat Seram Regency, Laimu Werinama Road Section with a Stretch Length of 300 M and a Width of 9 M. During the project implementation, the foundation work on the bridge was piling, where the planned piles that went into the ground were 1150 KN, but when tested using the Pile Driving Analyzer (PDA) Test, it had exceeded the planned limit, the piles that entered the ground were more than 3000 KN. The aim of this research is to analyze the bearing capacity value of a single pile foundation using analytical methods on the Wai Tunsa bridge, East Seram and to obtain a comparison of the calculation results using the analytical method and the results of the Pile Driving Analyzer test on the foundation of the Wai Tunsa bridge, Seram. East. In writing the methods used to analyze the bearing capacity of piles are the Meyerhoff method, Tomlinson method, as well as the reduction in pile foundations and well foundations is the Meyerhof method. The results of calculations carried out at 3 points, namely Abutment 1 (A1), Pier 1 (P1), and Abutment 2 (A2) on the Waitunsa Bridge work, Siwalalat subdistrict, East Seram Regency, from the results of manual analysis, it can be concluded that the Tomlinson method has good value. is closer than the Mayerhoff method to the PDA Test. Qu = 402.89 tons compared to 336 - 388 tons at A1, Qu = 384.74 tons compared to 373 – 389 tons at P1, and Qu = 397.57 tons compared to 347 – 389 tons.

Abstract

Retaining walls serve the purpose of withstanding lateral pressure from the soil behind them. This construction can be considered as an alternative for addressing potential landslides along the embankment of Hutumuri village road. The aim of this research is to plan a retaining wall as one of the reinforcement alternatives for the embankment along the section of Hutumuri road from Station (STA) 1+200 to 1+270. The planning of the retaining wall along this road section begins with a soil stability analysis using the simple slice method. Subsequently, employing the Terzaghi method, the stability of the wall against soil pressure behind it is analyzed to prevent displacement and potential collapse during the construction of the retaining wall. Utilizing the Simple Slice method and Rankine's theory to assess the slope conditions and the construction of the retaining wall along Hutumuri road section, values for the slope safety factor are obtained. In the unsafe condition, the slope safety factor is less than 1.2, indicating the need for an alternative slope reinforcement, such as a retaining wall. The analysis results for the stability of the Counterfort-type retaining wall indicate that it does not meet the requirements. This is due to the fact that, in section I, the soil bearing capacity safety factor (FS) is 2.454, where the value of FS is less than the recommended value of 3, signaling the need for further consideration and potential adjustments in the design.
