Abstract

Characterization of durability of mudrocks is important regarding its slaking behaviour within a short time when exposed to and or interact with water. Some relevant cases that occurred due to slaking are damage to roads and slope failures along the Cipularang and Cipali Toll Road. Current engineering activities related to the presence of mudrocks are being and will be held in several locations in Indonesia such as the construction of the Cisumdawu Toll Road in Ujungjaya District, Sumedang and building the National Observatory in Timau District, Kupang. This research is useful for providing engineering considerations related to those activities. The methods used in this research included X-ray diffraction to obtain mineralogy of mudrock, laboratory testing of physical properties of rocks such as dry density, water content, porosity, absorption and mudrocks durability tests. Durability of rocks was determined by disintegration index test. Testing was carried out by wetting and drying of rock samples. Test results showed that the average disintegration ratio of claystones, shales, mudstones and siltstones are 0.1035, 0.2183, 0.4942 and 0.9900. Slaking mode occurs to claystones, mudstones and shales is body slaking while dispersion slaking occurs to siltstones. Evaluation of the durability of mudrocks in this research indicates that siltstones have the highest durability characterized by very slow disintegration, followed by mudstones, shales and claystones at the lowest with very quick disintegration. Disintegration ratio from the disintegration index test characterizes the durability of mudrocks in more details. It can be concluded that porosity and absorption are incorporated into the main factors affecting the durability of mudrocks.

Abstract

Batulempung seringkali mudah hancur dalam periode singkat ketika tersingkap ke permukaan dan atau saat berinteraksi dengan air. Hal ini dapat memicu beberapa permasalahan di dalam kegiatan rekayasa. Salah satu kegiatan rekayasa  yang sedang dan akan berjalan adalah pembuatan Jalan Tol Cisumdawu (Cileunyi-Sumedang-Dawuan) yang merupakan akses penghubung wilayah-wilayah di sekitar Bandung dan Cirebon. Akses jalan ini juga akan terhubung dengan Bandara Internasional Jawa Barat (BIJB) di Kertajati. Bagian ruas jalan ini di daerah Ujungjaya, Sumedang akan melintasi Formasi Subang dan Kaliwangu yang memiliki litologi utama berupa batulempung. Karakterisasi durabilitas jenis batuan ini penting dilakukan untuk menunjang aspek teknis kegiatan rekayasa di sekitar area tersebut. Metode penelitian yang digunakan adalah pengambilan sampel tak terganggu (undisturbed sample) di lapangan, uji pembasahan dan pengeringan (wetting-drying) di laboratorium berupa uji indeks disintegrasi, uji mineralogi lempung melalui difraksi sinar X (XRD), dan uji sifat-sifat fisik batuan yang mencakup kadar air alami, densitas kering, porositas, dan absorbsi. Hasil penelitian menunjukkan indeks-indeks durabilitas batulempung dalam penelitian ini tergolong rendah. Disintegrasi batuan berlangsung cepat dan menunjukkan perilaku body slaking. Faktor-faktor yang berpengaruh kuat terhadap durabilitas batulempung terdiri dari porositas dan absorbsi. Hubungan porositas dan absorbsi dengan indeks durabilitas (rasio disintegrasi) mengikuti suatu kurva eksponensial negatif. Rasio disintegrasi cenderung turun seiring kenaikan nilai porositas dan absorbsi batulempung.

Abstract

The construction of the Tugu Dam spillway does not escape the problem of slope instability, especially the rock fall type landslide as a result of the rock slope cutting work at STA+80. The purpose of this study was to determine the characteristics of the rock discontinuity area and the solutions needed to address the potential hazards of rock fall on the slopes of spillway structure. In this study, a semi-quantitative method conducted based on the Rockfall Hazard Rating System (RHRS) which is carried out by identifying outcrops on rock slopes. Determination of the rock fall trajectory, was conducted by statistical methods on rock mass based on changes in velocity when rocks roll, slide, and bounce. Geologically, the research area belongs to the Mandalika Formation. Based on the RHRS weighting, the total score on the STA+80 slope is 399, which means that the slope needs to be repaired or given safely with a moderate level of urgency. The rock fall trajectory modeling at the measurement location X = 121,875 has a kinetic energy of 973.14 kJ andesite and 72.59 kJ of volcanic breccia, for high results of 0.43 meters of andesite reflection and 2.04 meters of volcanic breccia, and velocity results translational velocity obtained at 33.8 m/s andesite and 8.67 m/s volcanic breccia. The potential for rock fall requires a safety system with a type of retained flexible barriers with a height of 5 meters that can be applied to the toe of the slope.Keywords: rock fall, discontinuity, trajectory, protection system, Tugu Dam

Abstract

Kejadian longsor dangkal di Desa Weninggalih mengakibatkan kerugian setiap tahunnya. Hal tersebut diakibatkan oleh salah satu budaya warga setempat yaitu membuat kolam ikan tanpa dilapisi lapisan kedap air sehingga diduga menjadi salah satu faktor penyebab menurunnya kestabilan lereng. Sebagai upaya untuk mengurangi risiko kerugian tersebut dibutuhkan pemahaman yang baik mengenai karakteristik longsor dan pengaruh keberadaan kolam ikan terhadap kondisi kestabilan lereng. Penelitian ini bertujuan untuk mengetahui tingkat kestabilan lereng dan pengaruh keberadaan kolam ikan untuk studi kasus di daerah Weninggalih. Metode yang digunakan dalam penelitian ini meliputi pemetaan geologi, pemetaan topografi detail, pengukuran electrical resistivity tomography (ERT), pengambilan sampel tanah, pengujian geoteknik, dan analisis kestabilan lereng. Metode kesetimbangan batas dengan perhitungan Morgenstern-Price digunakan untuk analisis kestabilan lereng. Daerah studi terdiri dari produk vulkanik berupa tanah residual dan tuf tebal yang bersifat lepas dan kuat geser dalam yang rendah. Hasil analisis ERT menunjukkan adanya perluasan zona jenuh air yang diakibatkan oleh keberadaan kolam ikan. Analisis kestabilan lereng menunjukkan bahwa kemunculan zona jenuh air yang meluas menyebabkan menurunnya nilai faktor keamanan lereng secara signifikan.  ABSTRACT – The effect of water saturated zone on slope stability in Weninggalih, Bandung BaratRegency. Shallow landslides inWeninggalih Village resulted in many losses every year. One of the contributing factors is the customs of building a fishpond in the sloping ground without an impermeable liner. Consequently, the seepages from the pond cause the decrease in slope stability. To reduce the risk of loss, a better understanding of the landslide’s characteristics and the effect of the fishpond on the stability of the slope is required. The purpose of this study is to determine the level of slope stability and the influence of the fishponds to slope stability in the Weninggalih area. Methods used in this study include geological mapping, detailed topographic mapping, electrical resistivity tomography (ERT), soil sampling, geotechnical laboratory testing, and slope stability analysis. The limit equilibrium method with the Morgenstern- Price formula was used for slope stability analysis. The study area is composed of volcanic products consisting residual soil and thick tuff that are loose and having low shear strength. Results of ERT analysis showed the extension of the water saturated zone caused by the presence of fishponds. Analysis of the slope stability shows that the expanding water saturated zone causes a significant decrease in the slope safety factor.

Abstract

Penyimpanan akhir limbah radioaktif bertujuan untuk menjaga agar zat radioaktif tidak terlepas ke lingkungan sampai aktivitas zat tersebut turun ke level yang aman. Konsep penyimpanan akhir limbah radioaktif (LRA) yang akan dikembangkan di area Pusat Penelitian Ilmu Pengetahuan dan Teknologi (Puspiptek), Serpong adalah penyimpanan akhir limbah radioaktif dekat permukaan (near surface disposal - NSD). NSD berdasarkan kedalaman terbagi dua macam yaitu NSD dekat permukaan dan NSD kedalaman menengah. Konsep NSD pada penelitian ini adalah NSD kedalaman menengah, yaitu antara 30–300 meter. Pada saat konstruksi NSD di kedalaman menengah dibutuhkan pekerjaan ekskavasi bawah permukaan atau pembuatan terowongan. Analisis tegangan in-situ dan deformasi bawah permukaan dilakukan untuk mengetahui besaran dan distribusi tegangan yang terbentuk di dalam tanah/batuan serta deformasi yang terjadi pada saat dilakukan ekskavasi bawah permukaan. Berdasarkan analisis diketahui nilai tegangan dan sebaran tegangan tensional maupun kompresional berkisar antara -441 kPa sampai 4,028 kPa dengan nilai deformasi alami atau tanpa perkuatan antara 4,4 cm sampai 13,5 cm. Nilai deformasi yang cukup besar dimana mencapai 13,5 cm menunjukkan diperlukan rekayasa perkuatan pada saat ekskavasi. Desain rekayasa perkuatan pada setiap tahapan ekskavasi mengacu hasil pemodelan pola distribusi tegangan dan deformasi. Final disposal of radioactive waste intended to keep radioactive substances does not released to the environment until the substance activity decreased to the safe level. Storage concept of radioactive waste (RAW) final disposal that will be developed at the area of Puspiptek, Serpong is near surface disposal (NSD). Based on depth, NSD divided on two type, near surface NSD and medium depth NSD. Concept NSD in this research is medium depth NSD, which is between 30–300 meters. During NSD construction in medium-depth required the works of sub-surface excavation or tunneling. Analysis of in-situ stresses and sub-surface deformation performed to recognize the stress magnitude and its distribution that developed in soil/rock as well as the deformation occurred when sub-surface excavation takes place. Based on the analysis, acknowledged the magnitude of tensional and compression stress and its distribution that range from -441 kPa to 4.028 kPa with values of natural deformation or without reinforcement between 4.4 to 13.5 cm. A rather high deformation value which is achieved 13.5 cm leads to necessity of engineering reinforcement during excavation. The designs of engineering reinforcement on every excavation stage refer to the result of modeling analysis of stress and deformation distribution pattern.

Abstract

The massive infrastructure works in Indonesia currently requires good planning and implementation. The research location is included in the spillway construction project of the Tugu Dam. The bearing capacity research is limited by calculated for the deep foundation in the boredpile type with a diameter of 0.8 meters used SPT (Standard Penetration Test) data. SPT testing is carried out based on SNI 4153:2008. Calculated of ultimate end bearing capacity (Qp) on volcanic breccia and andesite has a value of 19.60 Tons. Meanwhile, the value of ultimate frictional resistance (Qs) in this volcanic breccia and andesite has a value of 0.84 Ton, this ultimate frictional resistance value increases according to the planned depth of the foundation and is adjusted to the building loaded. The altered sandy silt layer, the ultimate end resistance (Qp), and the friction blanket resistance (Qs) varies according to the average value of N-SPT. The difference in the value of N-SPT in the same soil layer is due to geological processes such as hydrothermal alteration and rock weathering.

Abstract

On 2018 September 28, 18:03 a local time (10:03 am UTC), the Mw 7.5 earthquake with a focal depth of about 20 km devastated the Palu region in Central Sulawesi, Indonesia resulting in a catastrophic disaster and many casualties. The Palu earthquakes triggered widespread landslides upstream, contributing to the sizeable material volume accumulated in rivers and mountain slopes. After the Palu earthquake, from September 28, 2018, until December 2021, at least 24 events of debris floods have occurred, which have spread to 15 villages. As of late, the empirical debris flow model Flow-R, software for susceptibility mapping of debris flows at a regional scale, was published. While Flow-R's applicability on a regional scale has been confirmed in several studies, the calibrated case using back-analysis of individual debris flow events in Indonesia based on DEMNAS with a spatial resolution of 8.3 m has never been conducted. Local debris flows modeling using Flow-R was evaluated with three well-documented debris flow events on the break slopes on the west and east sides of the Palu Valley. Quantitative analysis was carried out in this study to assess the accuracy, positive predictive value, and negative predictive value of models. First, the result shows the individual back-analysis model of debris flows found good agreement between debris-flow paths predicted and documented debris flow path extent. However, the parameters for rheological properties and erosion rate required in the software are limited. Second, the quantitative analysis shows accuracy, positive, and negative predictive value, which varies considerably. Based on the study, Flow-R is not suitable for comprehensive hazard mapping but provides a direct information about possible run-outdebris flow paths. Furthermore, lateral spreading and friction of Flow-R model results can be used to calibrate the process with rheological properties and erosion rate in other numerical modeling software, either for forward or back analysis.

Abstract

Bidang diskontinuitas pada lereng di ruas jalan Tawaeli-Toboli KM 42-52 dapat menjadi bidang lemah yang memicu longsoran, di antaranya longsoran guling. Longsoran guling dapat terjadi pada blok tunggal yang menghasilkan jatuhan blok batuan (rockfall) dan dapat terjadi pada massa batuan yang diikuti perpindahan volume blok batuan yang besar. Metode empiris yang berbasis pembobotan diskret seperti klasifikasi Slope Mass Rating memberikan penilaian yang cukup konservatif terhadap potensi longsoran, sehingga pembobotan berbasis fungsi kontinuum bisa digunakan untuk mengevaluasi penilaian. Potensi tipe longsoran dan arah gerakan blok batuan pada lereng diidentifikasi dengan analisis kinematika. Pada empat lereng yang diinvestigasi, kualitas massa batuan berdasarkan klasifikasi C-SMR menunjukkan interval normal hingga baik. Hasil analisis kinematika menunjukkan bahwa potensi longsoran pada lereng yang diinvestigasi adalah longsoran gulng tipe direct toppling dengan nilai probabilitas kelongsoran terbesar 33%. Kedua metode tersebut mampu mengidentifikasi kondisi massa batuan dan potensi kelongsoran pada lereng. Metode empiris yang berbasis pembobotan kontinuum juga mampu mereduksi bias yang dihasilkan oleh pembobotan diskret.

Abstract

This study aims to determine the characteristics and classification of clay shale in West Java and their implications for tunnel stability under short and long-term conditions using the finite element method. Data were collected from projects in West Java containing clay shale spread over four rock formations, namely Cihoe (Tpc), Subang (Tms), Cantayan (Mtts/Mttc), and Jatiluhur (Tmj). Each formation has varying mechanical and engineering properties. The value of SPT from Cihoe formation can be categorized in three conditions, SPT < 40, SPT 40-60, and SPT > 60 for fully, highly to moderately, and slightly weathered, respectively. Meanwhile, the value of SPT of Subang formation can be categorized in two conditions, SPT < 60 and SPT >60 for fully and highly weathered, respectively. The data collected were analyzed to determine the Mohr-Coulomb (MC) and Hardening Soil (HS) parameters for Plaxis modeling. The model applied three variations of overburden thickness between 3 times, 6 times, and 9 times the tunnel diameter (3d, 6d, and 9d respectively). The greater the overburden thickness, the lower the surface deformation. The HS model gives better results than the MC model because it considers non-linearity. The minimum effective parameters needed to support tunnel during construction to meet the allowable deformation for 3d overburden conditions and the particular reinforcement system are c' 53kPa, ϕ' 28°, and E'50ref 30,000 kPa. Long-term conditions possess lower stability than short-term, while prolonged deformations increase after construction and provide a rise in tunnel lining stress that needs to be considered in the design stage. The application of 2D tunnel modeling needs to be carefully analyzed, thereby representing the behavior of a continuous or 3D tunnel structure.
