A Landslide is the movement of soil mass or rock constituents down the slope due to disturbance of soil stability. One of the factors that affect soil stability is the rainy season as happened in Sumberwuluh Village, Candipuro District, Lumajang Regency. The alternative used to stabilize the slope is by changing the slope geometry, then adding geoframe reinforcement. This study aims to determine the value of the factor of safety (SF) of unreinforced slopes, after changing the slope geometry, and after being given geoframe reinforcement. The method used in analyzing slope stability is the Ordinary/Fellenius method. The results of the calculation of slope stability without reinforcement using the Rocscience Slide software obtained a SF of 0.719, while the manual calculation obtained a SF of 0.7191. The two values of the safety factor are less than 1.25, which means that landslides often occur. The results of the calculation of slope stability after changing the geometry of the slopes obtained a SF of 0.828 where the value is less than 1.25 which means that landslides often occur. The slopes that have been changed geometry are added with geoframe reinforcement. The results of the calculation of slope stability using geoframe reinforcement obtained a SF of 1.315 where the value is more than 1.25 which means that landslides are rare or slope in a safe condition.

Currently, innovation continues to be developed to replace cement with other materials so that the use of cement as a building material can be reduced. Utilization of coal waste (fly ash) is an alternative to subtitude cement. From previous studies, fly ash mixed with alkaline materials in the form of NaOH and Na2SiO3 in a ratio of 1:5 can produce geopolymer concrete. This geopolymer concrete research was continued by adding bendrat wire fibers into the geopolymer concrete mixture. The method used in testing the aggregate, testing the compressive strength of normal concrete K225, testing the flexural strength of normal concrete and geopolymer concrete refers to SNI. Another additional material that is mixed is bendrat wire fiber. The research was carried out in the form of making flexible beams of 10 cm x 10 cm x 50 cm with fiber variations of 0%, 0.5%, and 1,0% at the age of 14 and 28 days. The results of the flexural strength test of the BN beam at the age of 28 days can withstand loads than BG. The average flexural strength obtained with variations of BN, BN+SB 0.5% and BN+SB 1.0% respectively were 2.796 MPa, 3.113 MPa, and 3.879 MPa. The results of testing the average flexural strength of geopolymer concrete beams at 28 days, obtained variations of BG, BG+SB 0.5%, and BG+SB 1.0% respectively were 0 MPa, 0.055 MPa and 0.104 MPa. In addition, geopolymer concrete cannot be used as a beam and the addition of bendrat wire fiber to geopolymer concrete cannot withstand the tensile load on the concrete.

Beams are part of the building structure that is important to consider when designing the structure. Some failures that occur in beams due to beam reinforcement are not installed such as planning/ design procedures, this problem can cause structural failure. Knowing the behavior of the beam structure due to the given load can help predict the strength of the structural beam and the comfort of the planned structure. To determine and predict the strength and comfort of the reinforced concrete beam structure due to the received load, experimental and simulation tests are carried out. VecTor2 simulation is used to predict shear, crack, and displacement forces in reinforced concrete beams when displacement loads are applied. The bond stress-slip effect (0.139) has a good effect on the strength and hysterical response of reinforced concrete beams. From the results of pushover testing and simulations, it is obtained that the ratio for load capacity ranges from 1.00-1.095. In addition, the installation of 135˚ hooks on stirrups shows that the crack behavior that occurs forms an angle of 45˚, this indicates that the bond between concrete and reinforcement is going well, this can be seen from the analogous behavior principle of reinforced concrete beams.

COVID-19 has spread around the world and has given a huge impact on people's lives. One of the changes in the COVID-19 condition is the travel pattern of people. Travel patterns can be explained in terms of the flow of vehicles, passengers, and people's mobility from the origin and destination zones within a certain area and period. On the other hand, it is known that travel patterns are an essential factor in solving transportation problems. The change of travel pattern data is needed for transportation planners and policymakers in providing safe transportation during the pandemic. In addition, data on travel patterns also play an important role in determining travel restrictions in an area to reduce the spread of COVID-19. This study tries to analyze travel patterns during the COVID-19 pandemic through an exploratory approach by taking a case study in the Bangka Belitung Province. The results of this study show that the mobility was dominated by intra-island trips during the pandemic, both within Bangka Island and Belitung Island. Furthermore, during the COVID-19 pandemic, the majority of people made changes to their routine's mobility. More than 50% of people did not return to their original travel patterns even though the pandemic conditions had entered the New Normal period. The most influential factor which makes people change their mobility is to take precautions from COVID-19.

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.
