Abstract

Kastoba Lake in Bawean Island Indonesia is a tourist attraction that has a level of vulnerability in landslide disasters. The landslides has been happen. From the large and small scale in the Kastoba Lake. Base on the problem, the landslides occured due to the field of derailment. According to the above statement, it was necessary to know the subsurface structure and the field of avalanche derailment in the kastoba lake area. This data was allowed by geophysical resistivity method which a dipole-dipole configuration with 4 measurement points. The acquisition of data was based on preliminary studies from the analysis of landslide vulnerability level maps (DEM Alos data processing) that have been done first. The results of lithological analysis with geoelectric resistivity methods in this research obtained three layers of subsurface structure, namely top soil (top layer) with a resistivity value of 7-110 Ωm, clay (middle layer) which was a resistivity value of 110-210 Ωm and lava (bottommost layer) which was a resistivity value of 210-357 Ωm. The field of gelincir in the research area was on the top layer of soil composed of weathering of rocks mixed with organic material or leaf/tree decay with an average depth of 7.25 meters. Thus, this research can be one of the parameters of landslide disaster mitigation in the development of geotourism in Kastoba Lake

Abstract

Permukaan tanah tidak semua berbentuk bidang datar, namun memiliki perbedaan ketinggian dan kemiringan pada setiap daerah. Perbedaan ketinggian tanah mampu mengakitbatkan terjadinya pergerakan tanah yaitu longsor. Keberadaan bangunan base transceiver station (BTS) tower di Desa Sukaresmi, Cisaat, Sukabumi yang berada pada daerah lereng curam dengan kondisi retaining wall dan pagar dalam keadaan retak dan mengalami penurunan tanah menjadi salah satu faktor yang mengancam keselamatan. Untuk mengantisipasi dampak kerusakan lingkungan bertambah parah dibutuhkan penanganan khusus. Penelitian ini bertujuan untuk melakukan analisis stabilitas dan perkuatan lereng menggunakan software Plaxis2D. Adapun metode penelitian dilakukan dengan melakukan investigasi lapangan secara langsung, pengujian laboratorium, analisis stabilitas perkuatan lereng dengan software Plaxis2D serta rekomendasi perbaikan drainase. Upaya perkuatan lereng dengan mengganti dan memperdalam retaining wall existing. Hasil perkuatan lereng dapat meningkatkan nilai safety factor menjadi 1,369, nilai ini lebih besar dari safety factor existing sebesar 1,302. Kata kunci: cisaat, longsor, Plaxis2D, stabilitas lereng. The soil surface is believed to have differences in height and slope in each region. The different elevation could cause land movements namely landslides. The existence of tower base transceiver station (BTS) buildings in Sukaresmi Village, Cisaat,  Sukabumi on a deep slope area with cracked retaining walls and fences condition which experienced settlement is one of the factors that threaten safety. To anticipate the impact of environmental damage getting worse requires special handling. The aim  of this study is to analyze the stability and slope reinforcement using Plaxis2D software. The research method is carried out by conducting direct field investigations, laboratory tests, reinforced slope stability analysis with Plaxis2D software and drainage refinement recommendations. Countermeasures to strengthen the slope are done by replacing and deepening the existing retaining wall. The result of this measure is the increase of the safety factor value to 1,369, this value is greater than the value of the existing safety factor of 1,302. Keywords : cisaat, landslide, Plaxis2D, slope stability.

Abstract

The drought is one of the biggest problems for the community, this problem will be slightly resolved if the regions have a groundwater sources. This research has been carried out in the karst area, Druju Village, Sumbermanjing District, Wetan Regency, Malang. The purpose of this study is  to determine the distribution of groundwater in the Wonorejo Village, Malang District. The method that used is the Self Potential (SP) method using leap frog configuration with 104 measurement points. The results of this study indicate the value of electric potential shown between 0-13.5 mV, and assume that a low potential value (0-1 mV) is an indication of groundwater distribution. Areas with low potential values are found in four area. The area with the lowest potential value can be used as a reference in making wells. The possibility of groundwater distribution in this research area is not in one line / flow. However, it is possible that in areas outside the research location, groundwater flow is in one lane. Thus, to prove this assumption it is necessary to carry out further research in a wider area and the use of other geophysical methods to obtain more varied subsurface information.

Abstract

The road conditions which is always submerged can reduce the performance of the asphalt pavement. This research was conducted to obtain the characteristics of polymer asphalt concrete against flooding. Marshall testing was carried out on conventional and polymer asphalt concrete with optimum asphalt content treated with water immersion in variations of 0 days, 0.5 days, 1 day, 2 days, and 4 days. The results show polymer asphalt can improve the durability of asphalt concrete which is submerged in floodwater. This is indicated by the difference in the stability value of 113% in the variation of immersion for 4 days.

Abstract

The most fundamental of unsaturated soil is matric suction parameter. Matric suction in unsaturated soils plays an important role in controlling physical and mechanical properties. This parameter can influence some other important parameters of soil, such as effective stress, shear strength, swelling pressure, etc. Investigation of matric suction was performed on Ayer Hitam soil, at Batu Pahat District, Johor, Malaysia. Field monitoring works were conducted with and without dolomite treatment at the slopes of Ayer Hitam acidic soil. Field testing used some devices to find out the behavior of matric suction during the rainy session. The result shows that the soil matric suction with dolomite treatment is larger than without treatment and matric suction has a significant difference around 20 – 50 kPa. Enhancement of acidity from the dolomite treatment was not only decreasing pores size caused by the alternating of the microstructure of soil but also leading to increasing the matric suction. The treatment of dolomite material is able to control matric suction and increase the stability of slope acidic Ayer Hitam soil.

Abstract

Landslides are one of the factors caused by subsurface structures that are not compact, and have low density or resistivity values due to changes in groundwater. Rainwater that infiltrates into the ground will reach to an impermeable layer which is identified as a slip plane. This research was conducted in the Kastoba Lake area, Bawean Island, Indonesia. The purpose of this study is to determine the slip plane and the direction of the landslide in the studied area. Data acquisition was carried out based on a preliminary study of residual anomaly contour analysis from gravity data, then geoelectric data acquisition was carried out in the studied area. The results of lithological analysis on 3D geoelectric resistivity modeling in this study obtained three layers of subsurface structures, namely topsoil, clay, and lavas. The slip plane of the study area is above the clay layer (7.25 meters depth). The results of the 3D interpretation indicated that the direction of the landslide was towards the north, as evidenced by the existence of public information that the area studied had landslides with the avalanche direction towards the north.  For further analysis, a factor of safety analysis is needed based on the analysis of the bore hole drilling method in the studied area
