Abstract

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.

Abstract

The coastal area of Watu Ulo Beach in Jember has great resource potential but also the potential for major disasters, such as a tsunami. Tsunamis can cause casualties and destroy buildings. Thus, it is important to assess the possibility of future tsunami disasters. This study aims to simulate a tsunami at Watu Ulo Beach using Delft3D-Flow to analyze the possibility of affected areas. The tsunami modeling is based on two simulations, namely Scenario 1 as model validation using the characteristics of the 1994 Banyuwangi earthquake. Model validation calculation uses the MAPE method <10%. Scenario 2, modeling the southern Java megathrust earthquake, was analyzed to obtain the time and wave height as well as tsunami run-up and inundation, visualizing the area affected by Watu Ulo Beach. The simulation results show that the tsunami wave height at Watu Ulo Beach reached 12.57 m with a travel time of 29 minutes. The run-up elevation was 9.21 m, and the inundation distance was 2.38 km from the Watu Ulo coastline, indicating that the tsunami caused substantial damage. As an area affected by the tsunami, Sumberejo Village has an inundation area of 634.68 ha, and Sabrang Village has an area of 250.03 ha. The temporary evacuation location for Watu Ulo Beach is set at Tanjung Papuma Street via the shortest route of 0.57 km from the assembly point. Based on the results of this study can be used as a reference for determining temporary evacuation routes and locations for tsunami disaster mitigation in coastal areas.

Abstract

Landslides are one of the natural disasters that often occur in the Upper Tanggul Watershed. This study aims to produce a landslide susceptibility map based on the Geographic Information System (GIS). Seven landslides conditioning factors used, namely land cover, river density, slope, aspect, elevation, curvature and Normalized Difference Vegetation Index (NDVI). Landslide susceptibility areas were mapped using the frequency ratio and weights-of-evidence methods. The accuracy of the landslide susceptibility maps generated from both methods is validated using the Area Under Curve (AUC). The estimation results of the AUC plot show that the susceptibility map using the frequency ratio model has an accuracy of 92,6% and the weights-of-evidence method has an accuracy of 90,1%.

Abstract

Landslides are natural disasters that often occur in Indonesia. Landslides have occurred in Kemiri Village, Jember Regency. Kemiri Village is a densely populated area and there is a bustling agro-tourism area. This study aims to analyze the level of vulnerability to landslides using geoelectric tests and geotechnical tests. Geoelectric test is carried out to determine the lithological conditions at the site, geotechnical testing to obtain soil parameters as a determinant of the safety factor value of the research location. The results obtained from the geoelectric test showed a range of resistivity values between 0.72 to 267 and were types of silt to sandstone soils. The factor of safety obtained is between 1.042 - 1.862 which means the value of the factor of safety is relatively low. The value of this factor of safety indicates that in the research location there are still frequent land shifts which are feared landslides will occur.

Abstract

Soft soil problems in the Truck Maintenance Facility construction project became a major obstacle in the development process of the project. Soft soil has characteristics with low bearing capacity and compression that lasts a long time and large. One method chosen for the soft soil problem is to combine preloading with Prevebricated Vertical Drain to accelerate the consolidation process to match the age of geotechnical work on the project. Based on the results of soil investigation, improvement of soft soil can be divided into three areas (A, B, C) based on the characteristics and depth of the soft soil. The preloading height varies in each area. Area B requires the highest preloading height of 8.11 meters. The reason is that area B has a large thickness of soft soil. Only preloading in Area B requires special handling in the form of 6 layers of geotextile reinforcement on the embankment. PVD is used in all construction areas. The effective distance for installing the PVD found based on the results of the analysis on the two installation patterns, namely triangles and quadrilaterals, is the same as 2 meters. Therefore, even though the triangular pattern has a faster consolidation time, the rectangular pattern is better to apply because it has effectiveness in field installation.

Abstract

Paseban Beach is one of the beaches designated as nature tourism in the RTRW of Jember Regency in 2015-2035. In the strategic plan (RENSTRA) of Jember Regency for 2016-2021 Paseban Beach is also designated as nature tourism. Based on the RIPPDA document of Jember Regency in 2015, Paseban beach was designated as a natural tourism area with potential activities in the form of beach tourism. In the existing condition, the allotment of Paseban beach is used as nature tourism with massive tourism development. This is due to several factors, namely the tourism component that has not been fulfilled and human resources that are not ready for the development of Paseban beach tourism. So that many impacts occur on Paseban Beach tourism. One of the most prominent impacts on Paseban beach tourism is the problem of waste caused by tourist activities that are not balanced with the availability of tourism components and public awareness. This study uses primary data in the form of field observations and questionnaires and secondary data, namely literature studies and agency surveys. The research respondents used were sourced from tourist visits to Paseban Beach in 2015 as many as 15,000 people. Then the number of respondents was determined using the slovin technique with the results of 100 respondents. The method used in this study is a descriptive method to identify the characteristics of the tourism component of Paseban Beach and Importance Performance Analysis (IPA) to determine the priority of developing the tourism component of Paseban Beach. Based on the analysis that has been done, the results obtained are development priorities in quadrant A, namely gazebos, sign boards and tourist maps.

Abstract

The Piket Nol national route is an alternative route across the southern island of Java that connects the Lumajang Regency with the Malang Regency. Landslide-prone areas are starting from KM Turen 53 to KM Turen 59 on this route. The Simplified Bishop method is used in analyzing slope stability and modeling soil nailing reinforcement with numerical modeling. Slope and soil nailing stability control are applied following SNI 8460 2017. The average value of the safety factor for the natural slope's stability at the top of the road is 0.269 or less than 1.07 (unstable). Whereas the stability of the lower slope of the road in most locations shows a stable condition (SF>1.25), except for KM 57+100, KM 58+100, and KM 58+900 with an average SF value of 1,183 (critical). The average value of the safety factor for the top slope stability after reinforcement using soil nailing is 1,728, whereas for the lower slope stability is 1,853. Soil nailing is designed as slope improvement at KM 57+900, other than that in anticipation of the potential for landslides at KM 56+900-KM 57+700 and KM 58+100-KM 59+100. The results of all stability control of slope reinforcement using soil nailing have met the SNI 8460 2017 criteria. Therefore, soil nailing can be an alternative solution in dealing or anticipating with landslides on The Piket Nol national route. Key words: landslide, slope stability, safety factor, soil nailing, soil nailing stability.

Abstract

The Sub-watershed of Sampean Hulu, located on the slopes of Mount Raung is susceptible to erosion hazards. Erosion indicators have been observed in the irrigation channels, mainly due to frequent sedimentation, which compromises the irrigation infrastructure's optimization and water distribution. To address this, erosion monitoring using the Universal Soil Loss Erosion (USLE) model, along with GIS and remote sensing techniques, is essential. It was found that the irrigation networks associated with Clangap and Tamanan rain gauges are at higher risk due to intense rainfall. Maesan and Wonosari II rain gauges cover a larger irrigation network area, highlighting the need for erosion prevention measures. The dominant soil type, Tv, with a high clay content, is highly susceptible to erosion. Flat and gently sloping slopes have a lower risk compared to steeper slopes, while very steep and steep slopes pose higher erosion risks. Paddy fields and well-managed forest plantations have lower erosion hazards, while bare land and certain agricultural practices contribute to increased erosion risks. The analysis classified the erosion hazard into five classes, with the sub-watershed being predominantly low and very low susceptible to soil erosion. Implementing conservation practices, sustainable land management, and land use regulations are crucial for erosion prevention.
