: Claystone is a rock that has a denser structure with more mineral composition than siltstone. In addition, claystone can also be interpreted as a type of sedimentary rock that is clay or plastic, composed of hydrous aluminum silica (a clay mineral) whose grain size is fine and the claystone is often easily destroyed in a short time when it is exposed to the surface and interacts with water. From the test results it can also be obtained a comparison of rock strength values between location 1 and location 2 by correlating the results of testing the physical properties and mechanical properties of each location where for location 1 has a natural water content value of 17.38% and a saturated water content of 24.39% with the cohesion value of claystone under natural conditions is 0.209 MPa, saturated conditions are 0.2105 MPa and dry conditions are 0.2517 MPa. Then for location 2 it has a natural water content value of 22.87% and a saturated water content of 32.84% with a claystone cohesion value of natural conditions of 0.0923MPa, saturated conditions of 0.0377MPa and dry conditions of 0.2099 MPa. It can be concluded that the claystone location 1 has a smaller water content presentation than the claystone location 2. It can be concluded that the water contained in the claystone greatly influences the strength of the claystone in resisting the forces received to experience a shift and also water affects the attractive force between claystone particles which makes the strength of the rock weak.

Changes in land use due to open pit mining operations, indirectly affect the hydrological cycle. Open pit mining operations, especially the open pit method, greatly affect subsurface conditions, such as lithology and hydrogeology. The purpose of this study was to analyze the hydrological and hydrogeological conditions before mining on syncline folds in the Mahakam river. This research is an inductive research with an analytical approach which includes the study of land use, hydrological conditions, geology, and hydrogeology. The land use of the research area is dominated by plantations (84%) with a rain catchment area of 995.9 hectares. The results of the hydrological analysis yielded daily rainfall values with a 5-year recurrence of 208.4 mm, annual rainfall of 2.177.32 mm, runoff 238.63 mm/yr, evapotranspiration 1,031.16 mm/yr and groundwater recharge 907.53 mm/th. The lithology of the study area is dominated by sandstone and clayey siltstone. The results of the aquifer test (pumping test) showed that the average K value (hydraulic conductivity) of sandstone was 1.33 × 10-2 m/s and claystone was 6.77 × 10-10 m/s. The results of the hydrogeological analysis show that the top layer is an aquitard, below it is an aquifer, then an aquitard, and the bottom is an aquiclude. The type of aquifer in the study area is classified as semi confined aquifer

Bengalon is located in East Kutai Regency, East Kalimantan Province. Bengalon is included in the Samarinda-Bontang groundwater basin. The development of agricultural and industrial areas, followed by an increase in residential areas, will cause an increase in the water demand. This study aims to determine the groundwater potential of alluvial areas using the resistivity geoelectric method. The resistivity survey resulted in subsurface lithology, shallow groundwater conditions in the form of depth, thickness, and location of the aquifer as well as the type of groundwater quality. There are 10 locations for geoelectric data collection using the 2D geoelectric method. The results showed that the majority of the aquifers were alluvial deposits consisting of sand and sandy clay. The resistance indicating groundwater is 1 - 4 Ω m, at a depth of 10 – 50 m with a thickness varying from 10 – 20 m which has been dominated by sand. The presence of sea water intrusion in aquifers causes the quality of groundwater to tend to be brackish because the research location is in a swamp area bordering the coast.

ABSTRAKDampak penambangan batubara tambang terbuka adalah munculnya Air Asam Tambang (AAT) di sekitar lingkungan penambangan yang mempengaruhi kualitas air tambang, biota air, kualitas air dan tanah. Oleh karena itu, informasi awal untuk mengantisipasi dampak tersebut, yaitu identifikasi batuan yang berpotensi asam dan memodelkan penyebarannya. Kajian geologi dan mineralogi batuan berperan dalam mengetahui penyebaran batuan Potential Acid Forming (PAF) dan Non Acid Forming (NAF). Kawasan tambang yang digunakan sebagai model penelitian berada di Kecamatan Muara Lawa, Kabupaten Kutai Barat, Kalimantan Timur. Hasil dari penelitian mengindikasikan, bahwa dominasi PAF berada di lapisan batu lempung kemudian diikuti batu lanau dan batu pasir dengan penyebaran mengikuti struktur sinklin yang terbatas di lapisan bawah (floor) dan lapisan antara (inter burden) pada batubara. Sementara itu, batuan NAF menyebar menempati daerah selain batuan PAF.ABSTRACTThe impact of open pit coal mining is the emergence of Acid Mine Water (AMD) around the mining environment that affect the quality of the mine water, aquatic biota, water and soil quality. Therefore, early information to anticipate these impacts is the identification potential acid rock and distribution model as a guide for the mining plan. Geological and geochemical study of rocks is important in knowing the distribution of rock Potential Acid Formning (PAF) and Non Acid Forming (NAF). Mining area which is used as a research model was in Muara Lawa, West Kutai regency, East Kalimantan province. The results of the study indicate, that the dominance of PAF are in layers followed by siltstone, claystone and sandstone with the distribution of rock following the syncline structure in the bottom (floor) layer and in the inter-burden layer on coal. Meanwhile, rock NAF spread in areas other than rock PAF.

Abstract. Durability is defined as a measure of the rock's resistance to weathering and disintegration, when the rock undergoes weathering in a short period of time. This time the slake durability test was carried out with the testing standard of SNI 3406 Year 2011. This test used siltstone in the Balang Island Formation, Samarinda area. The particle size of the silt is midway between that of clay and fine sand. From the results of testing 8 samples of siltstone with 10 cycles that have been carried out, it can be seen that the siltstone in the Balang Island Formation tends to be stronger and the durability index value decreases relatively small from one cycle to the next. The value of Slake durability index (Id2) from each sample sequentially, namely 91.3%, 96.4%, 95.3%, 93.7%, 93.7%, 95.4%. 97.2%, 96.7%. The durability index test obtained an average durability index value (Id2) of 95%, where the value of siltstone at the research site is included in the very high classification. Abstrak.
