Abstract

Pile bearing capacity is the ability of the pile to support the load acting on the pile. The bearing capacity of the pile foundation must be greater than the load that occurs so that it can safely hold the building. Likewise for the pile foundation used in the construction of the Catholic Center Building, which must be able to support the loads that work on it. For this reason, it is necessary to calculate the bearing capacity of single or group pile foundations to support the load of the Catholic Center Building. Many methods are used to calculate the bearing capacity of piles, one of which is by using the equation proposed by Meyerhof (1976) which uses data from the Standard Penetration Test (SPT) obtained. In this method the value of N from the SPT results is used to find the pile end resistance and pile friction resistance. From the results of the calculations, the total weight of the Catholic Center (P) building is 20462 KN. The single pile bearing capacity based on the first point is 320.2 KN and the second point is 550.7 KN. The total bearing capacity of the pile group contained in the Catholic Center Building Construction based on drilling point one is 17261 KN and drilling point two is 30179 KN. 24255 KN. Thus the pile foundation in the construction of the Catholic center building is able to safely support the weight of the building, namely Qa = 24255 KN > P = 20462 KN.

Abstract

The truss structure of the bridge is formed from several arrangement of rod elements which are connected by joint joints at the point of connection. The actual conditions in the field on the main frame structure of the Way Mamua bridge, Leihitu District, Central Maluku Regency, have dimensions of the steel cross-section that are quite large and not optimal, so that in this present study aims to analyze the rod forces of the Way Mamua Bridge structure and optimize the cross-sectional dimensions of the Way Mamua Bridge trunk frame. The methods used in this study are the ritter and cremona methods, as well as cross-sectional optimization simulations using the help of the SAP2000 program. Loading Standards for Bridges based on SNI 1725:2016 and Steel Structure Planning Standards for Bridges are used by SK regulations. SNI T-03-2005. Based on the results analysis of the rod forces of the Way Mamua Bridge structure, a minimum bar force was obtained for the upper horizontal bar, the lower horizontal bar and the diagonal bar totaling 2 bars. The maximum bar force for the upper horizontal bar is 1 bar, while the lower horizontal bar and diagonal bar are 2 bars with accepted forces namely compressive and tensile forces. The optimization results obtained an increase in the percentage of cross-sectional dimensions to the cross-sectional area for the upper horizontal bar by 2%, the lower horizontal bar and diagonal bar experienced a percentage reduction of 64% and 54% of the cross-sectional dimensions under actual conditions in the field. From the optimization results, the voltage ratio is not > 1 so that it can be concluded that the bridge bar truss structure is still in safe condition.

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.

Abstract

The Buria-Riring Road section is located in Taniwel District, West Seram Regency, Maluku Province. This road section was built in 2019. However, in the middle of 2021 this road experienced damage. The topographic condition of the road section is in the mountains with many hills and slopes, plus the high level of rainfall means that rainwater that falls directly floods the road body and damages the pavement structure. With this condition, people no longer feel comfortable accessing this road. The purpose of this study is to determine the type of damage that occurs and what factors cause the damage, as well as find solutions to overcome the damage that occurs in the form of planning pavement thickness and planning drainage channel dimensions. The method used for planning the thickness of the flexible pavement is the 2017 Pavement Design Manual and calculating the dimensions of the drainage channels. From the results of the analysis, the type of damage that occurs is the release of grains (Raveling) and the causative factors are not built drainage channels and the carrying capacity of subgrade soils that are less stable. From the calculation results, it is obtained that the thickness of the stabilized subgrade is 175 mm, the aggregate base layer for class B is 100 mm, the base layer for class A aggregate is 200 mm, the burda with an aggregate size of at least 20 mm. And from the results of the calculation of the dimensions of the drainage channel, it is obtained that the width of the base of the channel is 55 cm, the width of the top of the channel is 90 cm and the depth of the channel is 75 cm.
