Abstract

Kabupaten Lumajang merupakan wilayah yang rentan terhadap tsunami karena berbatasan langsung dengan Pantai Selatan yang menjadi pusat gempa bumi serta keadaan pesisir pantai selatan Lumajang yang memiliki tingkat kepadatan penduduk dan pemukiman, aktivitas pemerintahan dan perekonomian yang tinggi. Pemetaan tingkat kerentanan tsunami perlu dilakukan sebagai informasi mitigasi dan rencana tata ruang wilayah. Lokasi penelitian adalah 5 (lima) kecamatan di pesisir Pantai Selatan Lumajang yaitu Yosowilangun, Kunir, Tempeh, Pasirian, dan Tempursari. Tujuan penelitian ini adalah membuat peta kerentanan tsunami Kabupaten Lumajang menggunakan Sistem Informasi Geografis (SIG). Pendekatan variabel kerentanan meliputi elevasi daratan, kemiringan, morfometri pantai, penggunaan lahan, jarak dari pantai dan jarak dari sungai. Metodologi penelitian antara lain pengumpulan data primer dan sekunder, pengolahan data parameter yang mewakili tiap variabel kerentanan serta pemberian bobot dan skor. Hasil kajian ini menghasilkan peta-peta variabel kerentanan wilayah penelitian yang selanjutnya dapat digunakan untuk kebijakan pemerintah daerah dan tindakan mitigasi seperti pemetaan tingkat risiko tsunami.

Abstract

One of the important oil and gas industry is oil and gas pipeline which serves to support the gas transmission and distribution process. The oil and gas pipeline routes are so long and cross through some areas that certainly raises the risk of adversely affecting the environment, especially for the pipeline located in a densely populated area, where at certain conditions, the pipe can leak and may cause the explosion. Many researches have been conducted concerning on the project pipeline risks which concluded that the oil and gas pipeline project has very complex risks. In addition, the oil and gas project may cause a potential disaster. Currently oil and gas companies have been implementing risk management to minimize the negative impacts, but the negative impacts are still occurred. This is due to ineffective risk management implementation. This study aims to analyze the effectiveness of risk management system for oil and gas pipeline project in Java Island. Based on a deep study literature review, it shows that the effectiveness of risk management can be achieved by taking account into environmental, social and economic factors that are the pillars of sustainable development system. The potential disaster was also to be considered as an addition factor. Therefore, four identified factors were analyzed using Analytical Hierarchy Process (AHP) method. Data were obtained using questionnaire which were distributed to oil and gas project team. It is found that the most factors to be considered was social aspect (40%) and the other factors contributed 31% for disaster, 15% for economic, 14% for environment. Those factors should be taken account in the design stage as the most priority.

Abstract

The resistivity method is one of the geophysical methods used to identify the aquifer layer by utilizing the rock response to the flow of electric current. This method considered more effective and can give a good subsurface cross-section, especially the fluid response. In this research, 3D modelling for identify geometry of subsurface geological structures of this study focus in three area (Plintahan, Duren Sewu, and Karangjati) using 2D resistivity data. Data Measurement of 2D resistivity using Wenner-Schlumberger configuration with length of each line is 155 meters and the target depth is 30 meters. The purpose of this configuration is to get an inverse with a resolution that is good to the lateral and vertical. The results show that the types of rocks in the research area was clay, sand and sandy shale with resistivity value 50-150 ohm-meter where sand rocks interpreted as aquifer rocks at depths of 2-7 meters and a thickness of 2-5 meters. The result of the resulting 3D modelling showed that the aquifer layer in Plintahan area showed the geological continuity with anticline geometry, in another area the aquifer layer in Durensewu - Karang Jati area showed the aquifer geometry prediction but there is no continuity of the structure of each other.

Abstract

The development of an urban area must be supported by the construction of infrastructure such as public facilities. The crowded of urban area in Indonesia increasingly requires the existence of a mass transportation mode that is capable of carrying passengers in large amounts and relatively quickly. Recently Jakarta has proposed the construction of the MRT (Mass Rapid Transit) with underground lines utilize tunnel technology. Tunnel system was chosen as an alternative solution socioeconomic problems in the land problem and conditions of the existing urban planning. The geographical position of Indonesia is located in the equatorial zone which is the weather conditions have high levels of weathering and moisture or high humidity, this condition may result in changes in the level of strength of rock of the tunnel system in a relatively fast. In the construction of public facilities with the tunnel system need monitoring system the condition of the tunnel to avoid the dangers that may occur due to the failure of a tunnel system. To determine the level of moisture and water content in the rock or overburden a tunnel can be determined by utilizing the resistivity method. Resistivity method is a geophysical method that measures the magnitude of the resistivity of a material. Changes in moisture content and humidity levels of rock or soil in an area can be indicated by a change in the value of resistivity of rock or soil. In the measuring of the resistivity method needed good design to provide accurate information, especially if it will be used as a monitoring system for a tunnel. Development of measuring the resistivity method, and in particular data processing is done with the aim of optimizing the measurement process and the measurement results can be interpreted easily and be able to demonstrate a phenomenon that occurs in rocks or soil cover tunnel.

Abstract

Indonesia lied among the three of world major plates so that several districts along the southern coast of Java Island were vulnerabled to the tsunami including Lumajang. South coast of Lumajang had high population density and settlements and high levels of government and economic activity. Therefore, it is necessary to know the level of insecurity and vulnerability to the tsunami in order to be utilized as input of mitigation data for the preparation of regional spatial plans (RTRW) based on tsunami risk level. The objective of this research is to arrange the regional risk map for tsunami in Lumajang Regency using Geographic Information System (GIS) through approach of insecurity and vulnerability analysis of tsunami. The insecurity rate is analyzed based on seismicity map and run-up data of tsunami event in Lumajang District. Vulnerability approach used multicriteria such as land elevation, slope, coastal morphometry, land use, distance from the coast and distance from the river. The methodology that was used included data collections of both primary and secondary data such as satellite imagery of earth map, Lumajang statistical data. Each vulnerability data variable was processed to result a weighting and scores that its become the parameters for making a regional tsunami vulnerability map. The results showed three level of risks in five subdistricts that directly adjacent to the Southern Coast such as Yosowilangun, Kunir, Tempeh, Pasirian, and Tempursari. The high tsunami risk which covered almost along the coast, the ramps morphology, without any protective vegetation and human activities at the site while the medium of tsunami risk which were in areas with elevation more higher than the coastal and the low of tsunami risk had variations of topography, quite far from the coast and less human activities.
