There is a potential overflow of a river during rain, resulting in water levels raised beyond normal water levels in the Sentiong Underpass Area, Jakarta in which is one of the strategic locations in Central Jakarta. To guarantee and maximize water flow in the Sentiong Underpass area, a water discharge regulatory system was created to be the form of underground wall structures equipped with pump houses. This wall structure is made of reinforced concrete structures underground at ± 3 m depth. This research aims to evaluate and analyze the underground wall capacity with reference to principles designed by SNI 2847-2013 and SNI 1727-2013. Analysis of data used based on field data including soil test parameters and vehicle traffic. Structural analysis which used is Computer Program (STAADPro), then based on the data obtained from the results of analysis and evaluation can be determined magnitude of displacement and dimensions of the reinforcement. The wall structure in Sentiong Area, Jakarta was planned to use K-300 concrete as high as 3 m underground, 40 cm of wall thickness, bottom floor thickness 40 cm, and upper floor thickness 20 cm. The total length of this underground wall structure was planned 32 m. Based on the results of the analysis, it was found that displacement and capacity structure qualified safely with design steel reinforcement diameters of D13 mm and D16 mm.

Engineered Cementitious Composite (ECC) concrete or micromechanical modeled concrete using analysis of a mixture of fiber and other added materials can produce a tensile strain capacity of up to three hundred to five hundred times compared to the strain capacity of conventional concrete. A review related to several studies that have been carried out previously on the properties of ECC and their constituent materials is presented in this paper. The behavior of the material is reviewed as an investigation parameter followed by determining the composition of the mixture, namely the effect of the water-cement ratio, the shape and length of the fiber and the addition of additives. The fiber volume fraction review was limited to between 2% to 3%, which resulted in outstanding tensile strain behavior. As it is known, ECC has an excellent capacity in terms of strain behavior which is accompanied by a large number of mico cracking patterns. ECC crack widths are usually predominantly less than 100 μm. ECC behavior is closer to that of steel which can bend or be ductile, whereas conventional concrete is brittle.

Palembang is famous for the Musi River with a length of 460 km. The area along the river border is vulnerable to the impact of floods, this is the same thing that occurs in the Gandus District, which is mostly located on the banks of the Musi River. Analysis of the flood water level profile along the banks of the Musi River, which is affected by the tides is needed to find out how big the impact of flooding in the study area is. It aims to determine the type of tide, the amount of flow discharge, and simulation of river water level. Primary data was taken using a current meter to determine the speed of river flow. Some of the secondary data needed are river channel topographic data, rainfall data for 10 years, channel cross-section data and Musi River level data. The analysis was carried out in the form of a simulation of flood water level with the help of the HEC-RAS 5.0.7 program. The tidal type of the Musi River is based on the results of the study in the form of Diurnal Tide, with a watershed area of 2.2 km2 in Gandus District, the runoff discharge is 280.34 m3/s. The simulation results with the help of the HEC-RAS program obtained an average runoff height on the Musi River border of 2.7 m. The high runoff from the simulation can have a negative impact on the surrounding community, so there needs to be serious handling for flood control.

Some areas of South Sumatra Province are peatlands scattered in the eastern part, starting from the districts of Musi Rawas, Musi Banyuasin, Ogan Komering Ilir, Muaraenim, and Banyuasin. Around 769,000 hectares of peatland are located in the Ogan Komering Ilir Regency area. Ogan Komering Ilir Regency is an area prone to forest fires. Therefore, it is necessary to conduct research on the characteristics of peat soils in the Ogan Komering Ilir area so that they can be used as consideration in efforts to prevent peatland fires. Sampling was carried out in Kotarayo Village, (Kayuagung District), SP 1 (Pedamaran Timur District), and Tulung Selapan Ilir Village (Tulung Selapan District). Peat soil samples were taken with ASTM D 7015-04 guidelines, and the physical properties of peat soil were tested for samples from the three locations. Based on its physical properties, peat soil samples are classified according to ASTM D4427-84. From the results of the research on peat soils in Kayuagung, Tulung Selapan, and Pedamaran Timur sub-districts, Ogan Komering Ilir Regency, peat soil samples can be classified as sapric-peat soil.

In Indonesia, earthquake-resistant structures are governed by SNI as design codes, which are updated on a regular basis. As a result, existing buildings with outdated requirements must be reviewed so that the building's performance may be assessed in light of the most recent codes. Pushover analysis and direct displacement-based design are used to characterize the real condition of the building in order to assess its performance. The 7-story reinforced concrete building structure in this study was designed according to SNI 03-2847-2002 and SNI-1726-2002. This structure will be evaluated utilizing the FEMA 440 and FEMA 356 procedures, as well as SNI 1726:2019. The results show that the structure meets the minimal performance limit criteria (which is life safety) in terms of displacement and drift values from the pushover analysis, based on FEMA 356 and FEMA 440 performance levels. The evaluation indicates better structural response parameter values (R, Ω0, and Cd) than that of SNI 1726:2019, indicating that the building performance is good and capable of withstanding the design earthquake load.

Nowadays, the developments of technology in construction are progressing very rapidly, one of which is mortar without using cement material. This encourages the development of concrete and mortar technology so that it can be widely used to repair structural or non-structural damages. In these conditions, a binder is needed in the form of an epoxy resin polymer with added fiberglass to get a strong material result in a short time. A mixture of 75% sand and 25% epoxy resin from the volume of the test object resulted a mortar compressive strength of 35.50 MPa with a specific gravity of 1.505 kg/m3. The results showed that the variation of the compressive strength of the epoxy resin mortar without fiber was higher than the variation with fiberglass. This was due to the addition of fiberglass reducing the composition of the percentage of epoxy resin which results in reduced bonding power in the mixture. The flexural strength of a mortar with variations using fiberglass was 8 MPa and showed the best performance, although the difference was not too far from the variation without fiberglass. This was because the addition of fiberglass can reduce cracks, so that the fibers can bind well. The tests had been carried out including tests of the compressive strength, flexural strength, and Scanning Electron Microscope (SEM).

Subgrade with poor strength and stability would cause the pavement to deform and crack easily. Different locations have different subgrade conditions. Different soil characteristics in different locations call for different treatment or stabilization measures. Poor subgrade strength is observed in Pronoyudo Street in Junrejo Sub-District, Batu City. This is evidenced by the cracked and chipped asphalt surface. The method used to determine the type and level of road damage in the study was Road Condition Index (RCI), while subgrade strength or CBR (California Bearing Ratio) was determined using DCP. In addition, sieve analysis was also performed for foundation material as well as testing water content and subgrade plasticity. Observations were made along 1,000 m (1 km) which was divided into 200 sq m. The analysis results showed a mean Road Condition Index (RCI) of 6.96% and the mean CBR value using the DCP tool was 2.48% (< 5%) with a DDT value of 3.39. A routine or periodic maintenance program is deemed to be the right management method for Pronoyudo Street in Junrejo Sub-District in Batu City. Therefore, overall, the program that has been carried out for road maintenance is in accordance with the results of research analysis and Public Works Ministerial Decree No. 13/PRT/M/2011.

The use of precast technology in the manufacture of segmental components for the bridge substructure is one application that can be used in the acceleration of bridge construction. Better concrete quality and precision are two advantages that can make precast technology a solution in accelerating bridge construction. Commonly, segmental precast concrete piers are not designed to resist earthquake loads; however, the use of segmental piers systems is still possible in seismic zones by limiting additional dead loads. This study discusses the load limitation using the dynamic response calculation methodology of segmental precast concrete pillar structures to the El Centro (1940) earthquake load by varying the slenderness of the piers/column between 22 to 100. Examination of the stress combination due to axial load (DL) and inertia load due to the earthquake is carried out to find out how much residual stress can be accommodated by the piers/columns. Additional dead load (WADD) is obtained by using Newton's second law by dividing the allowable additional inertial load based on the residual stress to the peak ground acceleration. The calculation results show a good correlation between piers’/columns’ slenderness and the proportion of additional dead load (WADD) to dead load (WDL), so that the applicability of using segmental precast concrete piers/columns in seismic zones can be predicted earlier through this correlation.
