Authors: Aulia Innocentia Eka , Rusdiansyah Rusdiansyah 
Published: December 2024

The phenomenon of soil scour is influenced by several factors, namely, continuous rainfall, slope, and soil movement. This causes landslides, especially on slope surfaces. The use of vegetation can be used as an effort to overcome shallow landslides on a slope.This study aims to determine the characteristics of the soil, the effect of plant roots on the shear strength of the soil by using a direct shear test tool and to determine the safety value on the slopes by using Geo5 application analysis. The types of plant roots used in this study were Paitan grassroots, Teki grassroots, Setaria grassroots, Gajah grassroots and Alang-Alang grassroots.From the results of the direct shear test, the shear strength value of the soil and Paitan grassroots was 101.433 kg/cm2, the soil with Teki grassroots was 99.392 kg/cm2, the soil with Setaria grassroots2, Alang-Alang grass is 123,730 kg/cm2 and the highest value is found in the soil and Gajah grassroots which is 105,7039 kg/cm2. With the characteristic form of fibrous roots and able to grow to very deep depths, the roots of these plants can have a great impact on soil shear resistance. The greater the diameter and root content in the soil, the greater the shear resistance. The presence of plant roots has proven to be helpful in increasing the holding moment even after erosion has occurred. It can be said that the presence of plant roots on slopes is one of the potential solutions as an effective, economical, and environmentally friendly method.

Published: December 2024

Currently, numerical methods have been widely used to analyze the case of deep foundations, both determining the bearing capacity and settlement due to loads that occur on the foundation. This method has been used to obtain friction bearing capacity and end bearing capacity to obtain the adhesion factor in soft soil.The purpose of this final project was to generate the respective values of the friction bearing and the end resistance of the pile cap on a loading test 200% of the design load through finite element simulation of FEM (Finite Element Method) using the Plaxis 2D program. This research began by collecting data from the N-SPT and CPT soil investigations, loading test data, and pile specification data. The soil investigation data were correlated into soil parameters (E, v’, c, dan φ) which were required by Mohr-Coloumb modeling on Plaxis 2D to produce end bearing and friction bearing capacities that were in accordance with the loading test results.The results of the loading test 200% of the design load carried out on the pile of TP No.101, As.Q-5 resulted in a friction bearing capacity of 15 meters of piles is 95.98 tons, and an end bearing capacity is 4.08 tons. And then, the TP No.58F-2E pile resulted in a friction bearing capacity of 15 meters long piles is 91.96 tons, and an end bearing capacity is 8.04 tons. The results shows that at a load of 200% of the design load carried out on the piles it can still be well supported by the friction bearing capacity of the pile cap, so that the end bearing capacity still receives a much less load than the load received by the friction bearing capacity.

Published: December 2024

Steel materials have a superiority in terms of strength, rigidity, and ductility compared to other structural materials, in addition to that with the material being detailed and high specific strength can produce a lighter structure. In this study, a redesign of the Banjarbaru City PUPR office building with a steel structure was carried out, this 2 (two) floor building with size of 24 x 36 m2 was previously designed using a reinforced concrete structure. The designed structure falls into the category of B seismic design and is designed with a common moment-bearing frame system (SRPMB). The design results are for the roof structure used double elbow profiles ⊥50.50.5, ⊥45.45.4, and ⊥30.30.3, for floor plates using floordeck with a thickness of 0.75 with a plate thickness of 110 mm and wire mesh reinforcement M8 – 175. For the child beam and the main beam successively use the WF 250×125×6×9 and WF 300 x 150 x 5.5 x 8 profiles, where the beams are designed as composite beams. While the column uses the H150x 150x10x15 profile. Rigid Connection is carried out at the connection of the moment-retaining beams while simple connection is carried out at the beam-beam connection. For the foundation used pile foundations with dimensions of 25x25 cm are staked to a depth of 6 m. The results of the structure comparison obtained that the effective weight of the steel structure is almost 50% lighter than the concrete structure, so that the basic shear force, displacement, and deviation between floors (story drift) that occurs are smaller. For the comparison of the foundation used with the same dimensions and depth in the steel structure, 2 poles are needed, while for the concrete structure it takes 4 pieces to withstand the load of the upper structure.
