The landslide on the Pihanin Bridge oprit towards Pihanin Village resulted in the interruption of land transportation routes and it was deemed necessary to repair. The landslide on the oprite was caused by the inability of the subgrade, which is relatively soft to support the Laterite embankment load as high as 4.5 m, with a specific gravity of 1.85 ton/m3 . The methodology used in handling the oprit is collecting secondary data in the form of road/bridge geometric data, soil investigation data (CPT/Sondir test and N-SPT test), soil data analysis, landslide analysis using GeoStudio 2012 software to estimate the landslide area with trial parameters. soil, so that sf < 1 is obtained which can be considered as a landslide field and the representative soil parameters are the same as those in the field. The next step is to calculate the load that refers to the SNI 1725:2016. From the results of the analysis, the design for handling landslides on the Pihanin bridge using box culvert type triple reinforcement with dimensions of length p = 8 m; width l = 10.2 m ; height t = 1.75 m, supported by 18 x 18 cm2 square piles, 12 m long. Analysis of the external stability of the slide shows the safety factor SF = 0.999 without reinforcement (existing condition) and SF = 2.622 with reinforcement (final condition). From the calculation of the forces acting on the pile in the form of an axial amount of 141.99 kN, with an allowable axial force capacity of 181.66 kN, while the lateral force that occurs is 4.96 kN with an allowable lateral force capacity of 216 kN.

Confinement plays an important role in preventing cracking and premature shear failure, increasing the compressive strength and increasing the ductility of the element. One of the most efficient retrofitting methods is the reinforcement method with external restraints using high quality materials. Based on previous research, the use of external restraints using high quality materials can be in the form of steel wire mesh and wire rope restraints, and high-quality fiber such as CFRP (carbon fiber reinforced polymer). In this research, a study will be conducted to determine the effect of CFRP confinement reinforcement on a concrete cylinder that will be modeled with finite element software. The dimensions of the concrete cylinder used have a height of 300 mm and a diameter of 150 mm. The concrete cylinder is reinforced with CFRP with a thickness variation of 0.5 mm; 0.7 mm; and 1 mm respectively, namely SC.1.05-F, SC.1.07-F, SC.1.10-F. Then the samples with variations in the number of layers of 1 layer, 2 layers, and 3 layers respectively are SC.1.10-F, SC.2.10-F, SC.3.10-F. The last is the sample with a variety of full wrap installation configurations, CFRP with a width of 30 mm with a spacing of 50 mm, and CFRP with a width of 50 mm with a spacing of 50 mm, respectively, namely SC.1.10-F, SC.1.10-T3, and SC.1.10-T5. From the results of the analysis, it can be concluded that CFRP is able to increase the compressive strength of the sample with each increase in the compressive strength capacity of the test object compared to the Control Cylinder (SK). Based on the results of the analysis for all samples SC.1.10-T3, SC.1.10-T5, SC.1.05-F, SC.1.07-F, SC.1.10-F, SC.2.10-F and SC.3.10-F respectively of 10.79%; 25.24%; 33.66%; 39.50%; 49.85%; 78.21%, and 94.5%.

Urban growth is inseparable from the development of settlements, city facilities and infrastructure, and other supporting facilities. Urban growth also occurs in Balangan Regency, especially in Balangan City. The development of urban planning is inseparable from the hydrological factor of the area. This study aims to evaluate the existing water system in Balangan City on the hydrological aspects of the area, especially in the office area and city growth. The evaluation includes the existing water system in Balangan City, the existing conditions, and how to plan for the future. This study proves that the air system's condition, especially the drainage system in Balangan City, is not well integrated, which is indicated by the absence of a comprehensive network system, making it difficult to evaluate the existing air system. Fortunately, this can still be covered by the hilly topography of Balangan City and the land use that is still not compacted so that water infiltration into the ground can still be expected as a solution. The need for an integrated system by taking into account urban open spaces.

Increasing number of warehousing areas in South Kalimantan Province is a positive impact in terms of regional economic development. However, the development of the warehousing area also has an environmental impact in the form of changes in land use showed by an increase in the area of warehousing areas which will result in an increase in the volume of surface runoff. As an effort to handle excess surface water due to warehousing activities is to use infiltration wells as a means of sustainable drainage. An area of 5.8 hectares located in the Bati-Bati sub-district, Tanah Laut district is the location where this research was conducted. The method used is a hydrological analysis of the rain and discharge that becomes surface run off and inundation in the area. The 5-year return period was chosen to provide recommendations for the dimensions of the infiltration wells that were applied. The results of the hydrological analysis of the 5-year return period are 53.9 mm/day. Design of wells is 1 m of width and 4 m of depth. The number of infiltration wells is 107 pieces.

At the beginning of the Covid-19 pandemic and implementing Large-Scale Social Restrictions or PSBB, many structural laboratories also closed their activities. At the same time, some construction work still had to run. For construction services to continue to exist, it is necessary to adapt the information, technology,communication, and data management departments.The compressive strength test of concrete using confined cubes and cylinders has been carried out using the finite element method. The test object is a cube of 15 cm × 15 cm × 15 cm and a cube of 20 cm × 20 cm × 20 with 5 cm stirrups and a cylinder with a diameter of 15 cm and a height of 30 cm, which is restrained by a stirrup distance of 5 cm and 10 cm. One way to get reinforced concrete material that is sufficiently pliable is to provide confinement to the concrete. Confinement is the most effective solution in increasing the ductility (μ) and strain (εc) of concrete. So that the research carried out is testing the compressive strength of concrete on cubes and cylinders that are given restraints to get the maximum load value that occurs.The effect of restraint on the cube test object is the stirrup distance which affects the maximum load value, the closer the distance between the stirrups, the greater the maximum load value. Meanwhile, the cylindrical cross-section with square restraints does not affect the maximum load value.
