The construction of dams is very important for fulfill water demand and as flood control. In addition to having many benefits, a dam also has a high risk. The stability of the dam is strongly influenced by the magnitude of the pore water pressure. The purpose of the study was to determine the response of pore water pressure to the reservoir water level, as well as to find out the comparison of the results of pore water pressure analysis using plaxis 2D and piezometer instrument readings. The piezometer readings are graphed as a function of the reservoir water level. Based on the graph, it can be seen that the piezometer readings correspond to the fluctuations in the reservoir water level. The piezometer upstream side have a faster response to the reservoir water level, which is between 14 to 41 days. While downstream piezometers have a longer response, which is between 25 to 61 days. Pore water pressure analysis using plaxis 2D at location P.17 (upstream) resulted in a smaller value than piezometer reading. While at location P.18 (downstream) it produces a greater value than the piezometer reading. The relative error value of the two analyses is 7.73% < 12% is still considered good, so the difference is acceptable.

Construction work needs to be controlled for its performance through productivity calculations in order to achieve optimal cost and time. Marble covering work has a considerable weight. However, studies discussing the calculation of labor productivity for marble covering work are still few. This study aims to determine the value of productivity, coefficients, and productivity levels of labor (Labor Utilization Rate) in completing the installation of marble coverings using the wet method for floor coverings and the dry method for wall coverings with parallel patterns and diagonal patterns. The study used a work sampling method with a productivity rating approach. Primary data were collected by sampling the volume of marble covers of 482.400 m² and observations on labor groups consisting of craftsmen and helpers in predetermined zones. Furthermore, analysis was carried out using quantitative techniques of parametric inferential statistical type where the data was confirmed to be normally distributed using SPSS software. The results showed that the labor productivity of marble floor coverings was 9.896 m² / day with a coefficient of craftsman and helper of 0.101 each and a Labor Utilization Rate of 58%. Second, the labor productivity of parallel pattern marble wall coverings is 12.589 m²/day with a coefficient of craftsman and helper of 0.159 each and a Labor Utilization Rate of 57%. The labor productivity of diagonal pattern marble wall coverings was 1,549 m²/day with the efficiency of craftsman and helper of 0.646 and the Labor Utilization Rate of 55%, respectively. The results showed that the labor of marble cover work is quite productive because it has a productivity level above 50%.

The Swamp Irrigation Area (DIR) of Dadahup District is a former Peat Land Development (PLG) with an area of around 21,226 Ha. The water management system at DIR Dadahup utilizes changes in sea tides as a source of water to the land and drainage to drain water out of the land. However, in its implementation, DIR Dadahup experienced several problems such as flooding during the rainy season and experiencing drought during the dry season. These conditions indicate the need for land management and water management systems to overcome existing problems. The purpose of this study was to optimize the water management system for irrigation by optimizing the functions and benefits of swamp land in Dadahup, Kapuas Regency, Central Kalimantan Province. Optimization of the water system is carried out by modeling using the HEC-RAS program. Flow modeling with HEC-RAS in irrigation canals can be simulated into two scenarios, namely scenarios using gates and scenarios with doors and pumps for the rainy and dry seasons. Based on the results of the modeling analysis that has been carried out, the surface elevation during the dry season is in the range of +0.06 ms/d + 0.77 m, which is below the average land elevation (+0.8 m MSL). experience drought because the water in the canals cannot irrigate the land. The water level during the rainy season is in the range of +0.82 ms/d +1.53 m, which is above the average land elevation. It can be concluded that irrigation canals cannot accommodate the overflow of water that occurs at the planned discharge so that the land is flooded. The scenario model is suitable for the Dadahup DIR land use, namely with the door and pump scenario, the water level elevation for the dry season and the rainy season can reach the target of +1.0 m, then the water level elevation for the rainy season can also reach the target of +0, 7m.

Bangka Belitung Province is one of the provinces implementing ETLE to reduce the number of traffic violations. The implementation of ETLE in Bangka Belitung Province has been applied since March 2022 which has given an impact on changes in driver behavior. Driving behavior can be said to be the reaction of the driver/ rider to the environment when driving a vehicle. Based on previous research, it is known that driving behavior can be measured through the Driver Behavior Questionnaire (DBQ). Therefore, this study adopts DBQ to measure changes in driving behavior due to the implementation of ETLE in Pangkalpinang. This study aims to find out how the behavior of driver using the road after the application of Electronic Traffic Law Enforcement (ETLE) at signalized intersections in Pangkalpinang. The result indicates that driver/ rider “have almost never committed a violation by not wearing a safety belt while driving” and “have almost never using a cell phone while driving or when the vehicle is stopped at an intersection when the traffic light is red since the implementation of ETLE”. It can be concluded that the results of the analysis of violations recorded on ETLE are in line with the results of the analysis of driving behavior. However, further analysis is needed to determine the significant impact of implementing ETLE on driving behavior. The application of ETLE is expected to reduce violations that can trigger traffic accidents. Furthermore, the results of this study can be used as a basis for determining policies related to the transportation sector, especially improving traffic safety.

From land value data sourced from the Central Bureau of Statistics of Jepara Regency that in Panggang Village, Jepara District, the transfer of land use for buildings is very high, which shows a percentage of 70.98%, therefore resulting in an open area in Jepara Regency for rainwater infiltration, especially in the main route segment is reduced, resulting in flooding and puddles in the city center location. Floods that occur are 40 cm to 80 cm high when it rains in the urban center area, there are several inundation points in the Jepara square, Kartini street, and Jepara's Chinatown area, and several other roads. The channel in Panggang Village is one of the infrastructures that supports the functioning of an urban system in Jepara City. In the existing channel along the Wiso River area, inundation often occurs every rainy season, so it is necessary to conduct a study to analyze the capacity of the drainage channel. The data used in planning is secondary data. Secondary data was obtained from the schematic drawing of the drainage channel and data regarding the dimensions of the channel and hydrological data. The hydrological and hydraulic data obtained were then analyzed to obtain the design discharge and drainage channel capacity. The design discharge is calculated using the rational method and the channel capacity is calculated using the HEC RAS 4.1.0 and EPA SWMM 5.1 software modeling. This study examines Drainage Channel Capacity Analysis to evaluate flooding based on the existing condition of drainage channels that affect the occurrence of flooding using HEC RAS 4.1.0 and EPA SWMM 5.1 software models. HEC RAS 4.1.0 software. Based on the results of hydrological analysis, the distributions chosen are Gumbel Type I Distribution and Log Pearson Distribution Type III. In the fit test, it was concluded that the Log Pearson Type III distribution method met the requirements because the Dmax value of -0.0202 was less than Do 0.41. and hydraulic analysis obtained by software HEC RAS 4.1.0 and EPA SWMM 5.1. at the 1 year return period there are 2 points that experience flooding and 4 points that are able to accommodate flood discharge. The flood points are scattered in several areas in Panggang Village, namely Jl. RA. Kartini and Jl. Youth. In dealing with flooding, it is necessary to re-plan the drainage for the 10-year return period in order to create security and comfort for local residents.

The empirical methods of intensity duration frequency are most often used with limited data. Its information is needed to design a drainage system. This study aims to obtain the best empirical method that can describe the curve of intensity duration frequency in Bekasi. These methods use the Mononobe, van Breen, and Bell methods and are then calibrated with intensity duration frequency curves derived from short-duration data (observation). The result shows that no empirical techniques best fit the words. However, the Mononobe method has fewer results than the Bell, van Breen, and observations. When the three practical methods were compared with the comments, the Bell method was the most suitable approach for determining the rain intensity for a return period of under five years. In contrast, the van Breen method was for a return period of more than five years.

The strong column-weak beam is a design concept that needs to be implemented and considered in the planning of building structures (high-rise and low-rise buildings). Generally, structural failure occurs at beam-column joints. Such failure occurred due to the lack of attention to good and correct design concepts. The detailing of reinforcement for columns, beams, and beam-column connections has not yet fully implemented the SNI-2847-2019 standard which results in the reinforcement cannot withstand the combination of tensile, compressive, and shear forces that occur during an earthquake. In addition, the incomplete design of strong column-weak beam in building planning causes the building to fail in the column structure when receiving axial forces. The purpose of this study was to analyze the structural damage and the disaster management system applied during the earthquake in Palu. The research is carried out by investigation/survey methods on the study area as well as checking and recording the data about damage condition of buildings and conducting a hammer test (non-destructive test) to get the strength value of the concrete. Testing result showed the compressive strength value of the f’c concrete used is 20 to 48 MPa. In addition, the details of stirrups reinforcement are also not fully understood about their function on beams and columns, which results in the installation of stirrup reinforcement does not meet the criteria for bending angles of 90˚, 135˚, 180˚ and the addition of tensile and compressive reinforcement lengths. The high potential for earthquake hazard causes Palu and its surroundings tend to have an earthquake risk. For this reason, it is necessary to implement disaster mitigation for Palu region, which aims to reduce the number of casualties when natural disasters occur, both human and property loses.

A reinforced concrete type retaining wall was built in 2017 to strengthen the slope stability of Rembangan highway, Jember Regency, Indonesia. However, in 2018 the building was damage. Until now, the cause of the failure of the retaining wall is still unknown. This study aims to evaluate the causes of the failure of retaining walls and the stability of retaining walls on the slopes of the Rembangan highway, Jember Regency. The research methodology begins with primary and secondary data collection before processing the data using conventional methods and auxiliary software. After data processing, data analysis was carried out to find conclusions about the cause of the failure of the retaining wall. Result analysis showed that the retaining walls have a low level of safety factor for rolling stability, shear stability, and bearing capacity stability. In addition, the factor of safety for the bearing capacity of the group pile foundation as a reinforcement of retaining walls also shows a smaller value than that charged. In addition, the group pile foundation can suffer a total settlement of 1.28 m.
