Abstract

On 22 February 2018 landslide occurred in Pasir Panjang Village, Salem District, Brebes Regency of Central Java Province, Indonesia. About 8 people were died, 4 people were injured and several infrastructures were damaged due to this landslide. This research is carried out to understand geological-geotechnical condition and to study the initiation mechanism of the landslide. Field investigation and UAV mapping are carried out to detect slip surface and define slope geometry. The rainfall-induced pore-water pressure is estimated by using the Slope Infiltration Distributed Equilibrium (SLIDE) model. Then, limit equilibrium method is used to estimate the safety factor of the slope, while the shear strength parameters are determined by applying back analysis approach that compared with data from laboratory tests. The results show that landslide occurred in permeable layer of silty sand overlaid above impermeable andesitic breccia. Results from back analysis indicate that the shear strength parameters and rainfall intensity are strongly influence the stability of slope against landslide.

Abstract

ABSTRAK - Pengamanan kegiatan penambangan bawah tanah dilakukan bertujuan untuk menjaga stabilitas dan keamanan lubang bukaan terowongan dari reruntuhan batuan. Pengamanan kegiatan penambangan bawah tanah diperlukan kajian rekayasa geologi teknik seperti pemetaan lapangan, perhitungan Rock Mass Rating (RMR), tinggi bukaan terowongan bawah tanah, waktu runtuh (stand-up time), serta dimensi keruntuhan (beban runtuh, tinggi runtuh, dan beban luas atap). Penelitian ini menggunakan data kondisi geologi secara umum, pemetaan lapangan, perhitungan Rock Mass Rating (RMR), waktu runtuh (stand-up time), dimensi keruntuhan (beban runtuh, tinggi runtuh, dan beban luas atap). Kondisi geologi secara umum di daerah produksi CBT_1106_RMU_NTH dan CBT_1106_RMU_STH berupa batuan porfiritik andesit dengan dominan mineral kuarsa, memiliki jenis tekstur kuarsa crusiform, terdapat beberapa kekar menerus dengan panjang 1-3 m yang terisi dengan mineral hard filling lebar 1-5 mm, kekuatan batuan termasuk medium strong, sebagian teralterasi oleh mineral silika. Nilai RMR untuk daerah CBT_1106_RMU_NTH lebih tinggi dibandingkan CBT_1106_RMU_STH karena adanya pengaruh kondisi air tanah dengan tingkat pelapukan yang berbeda. Waktu runtuh daerah CBT_1106_RMU_NTH dapat bertahan lebih lama dibandingkan CBT_1106_RMU_STH karena daerah tersebut lebih stabil. Dimensi keruntuhan CBT_1106_RMU_NTH lebih pendek dan lebih ringan dibandingkan daerah CBT_1106_RMU_STH. Penelitian ini memberikan rekomendasi tinggi bukaan efektif tanpa penguatan.Kata kunci: geologi teknik, RMR, waktu runtuh, tinggi runtuh, beban runtuh. ABSTRACT - Securing underground mining activities is done purposely to maintain the stability and safety of underground mining openings from rock debris. Securing underground mining activities requires geological engineering studies such as field mapping, calculation of Rock Mass Rating (RMR), underground tunnel height, stand-up time, and collapse dimensions (collapse load, collapse height, and roof area load). This study uses data on general geological conditions, field mapping, calculation of Rock Mass Rating (RMR), stand-up time, collapse dimensions (collapse load, collapse height, and roof area load). The general geological conditions in the CBT_1106_RMU_NTH and CBT_1106_RMU_STH production areas are porphyritic andesitic rocks with dominant quartz minerals, have a crusiform quartz texture type, there are several continuous joints with a length of 1-3 m filled with hard filling minerals 1-5 mm wide, rock strength including medium strong, partially altered by silica minerals. The RMR value for the CBT_1106_RMU_NTH area is higher than CBT_1106_RMU_STH due to the influence of groundwater conditions with different levels of weathering. The collapse time for the CBT_1106_RMU_NTH area can last longer than CBT_1106_RMU_STH because this area is more stable. The CBT_1106_RMU_NTH collapse dimension is shorter and lighter than the CBT_1106_RMU_STH region. This study provides a high recommendation of effective aperture without reinforcement.Keywords: engineering geology, RMR, stand-up time, collapse height, collapse load

Abstract

Groundwater hydrogeochemistry and water quality assessment have been conducted in western Tuban, Indonesia, which is characterized by its karstic features based on physicochemical parameters (pH, electric conductivity, total dissolved solids, hardness, Ca2+, Mg2+, Fe3+, Mn2+, K+, Na+, Li+, NH4+, HCO3-, Cl-, SO42-, NO2-, and NO3-) from 25 shallow groundwater samples. The Piper diagram implies the groundwater is of HCO3–Ca+Mg type with some Na+K–SO4+Cl type meaning that the groundwater in Western Tuban is influenced by the silicate minerals weathering, the dissolution of carbonate lithology, and seawater intrusion. Durov diagram shows that the evolution of groundwater is influenced by ion exchange with clay minerals and by mixing with seawater. The Gibbs diagram indicates that the change in the chemistry and quality of groundwater is caused by a dominance of rock-water interaction in the Western Tuban. The water quality assessment based on the USSL and Wilcox diagrams indicates a high level of salinity and relatively low sodium, meaning that the suggested crops should have good salt tolerance, and the cultivated soil should still be able to handle the relatively low sodium level for irrigation.

Abstract

Reservoir heterogeneity has long been recognized as a critical factor influencing the efficiency of enhanced oil recovery (EOR) methods. Among the techniques applied, cyclic waterflooding is considered one of the promising approaches due to its relatively simple operational design and potential to improve sweep efficiency. This method involves alternating water injection in specific cycles to mobilize trapped oil and redistribute reservoir pressure. However, the variation in geological properties such as porosity, permeability, and fluid saturation creates challenges in achieving uniform displacement, especially in reservoirs with high heterogeneity. Understanding the role of heterogeneity is therefore crucial for optimizing cyclic waterflooding applications. This study applies a literature review approach by synthesizing findings from previous experimental and field studies that evaluated cyclic waterflooding under different reservoir conditions. The analysis compares the performance of cyclic water injection periods across reservoirs characterized by varying levels of heterogeneity. Parameters such as injection rate, water breakthrough time, and oil recovery factor were considered in evaluating the effectiveness of this method. The results highlight that reservoirs with high heterogeneity often experience uneven fluid distribution, leading to early water breakthrough and reduced oil recovery. In contrast, reservoirs with relatively low heterogeneity tend to respond better to cyclic waterflooding, resulting in improved sweep efficiency and higher incremental recovery. Moreover, the optimization of cycle timing and water injection intervals appears to significantly mitigate the negative effects of heterogeneity. In conclusion, the study emphasizes that reservoir heterogeneity plays a decisive role in determining the success of cyclic waterflooding. Tailoring injection strategies based on geological variability is essential to maximize recovery efficiency. Future research should focus on integrating advanced reservoir characterization techniques with adaptive cyclic flooding models to further enhance oil production outcomes.
