Abstract

The limestone became exposed to the surface because of an uplift event during the Quaternary period. This study aims to determine the age of limestone outcrops in the Taeno Traverse using planktonic foraminifera. This research located in Negeri Rumah Tiga, Teluk Ambon District, Ambon City. Field observations and laboratory analysis comprise the two steps of the study methodology. Employ the measuring section approach to gather detailed data in the field. There are 12 layers in the track, totaling 5.34 meters in thickness and 16.5 meters in length. Foraminifera samples prepared in the laboratory using H2O2 extraction and each sample's planktonic foraminifera taxa were identified. Nineteen samples were processed and confirmed to be fossilized planktonic foraminifera. A binocular stereo microscope with a 40x magnification used to analyze the data. The Taeno traverse is composed of calcarenite, a type of clastic limestone. The main characteristics include brownish-grey color, good sorting, sand particle size, open packing, and rounded-subrounded grain shape. Based on the identification results, 30 taxa of planktonic foraminifera fossils were found. The species with the highest abundance are Globorotalia tumida tumida, Globorotalia menardii menardii, Neogloboquadrina incompta, Pulleniatina obliquiloculata, Orbulina universa, Globigerinoides tenellus, and Spaerodinella deshiscens. According to the biodatum results, the Taeno Traverse is part of the Globorotalia ttruncatulinoides truncatulinoides zone with Globigerinella calida calida, Globorotalia tosaensis tosaensis, and Globorotalia crassaformis crassaformis sub-biozonation. This zone shows the age range of N21-N23, or equivalent to the Pleistocene.

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

One of the energy requirements for fuel is in the form of solid hydrocarbons and as basic materials or feedstocks. Coal is formed from deposits of organic plant compounds that grow in an oxygen-free environment and are influenced by temperature and pressure for a long time. Based on the coal formation process, coal from the highest to the lowest level is anthracite, bituminous, sub-bituminous, and lignite. Low-grade coal has a faster oxidation rate than high-grade coal because it contains inherent moisture, oxygen, and carbon in large quantities, has high porosity, and causes an increase in activation energy resulting in evaporation and a continuous increase in temperature causing spontaneous combustion. Monitoring and control of coal, especially in the stockpile area as a temporary storage place, is carried out to prevent oxidation and self-burning, namely by arranging the piling pattern and applying demolition principles by taking into account the length of the pile, forming the design of the stockpile base surface, calculating the volume, height, side slope, and distance between piles, as well as taking into account wind speed and direction, which greatly influence particle size, porosity, and the rise in temperature of the coal during self-heating. Efforts to handle self-heating in coal can be made by creating drainage in the stockpile area, reducing the height, and forming a slope angle of 15–30° to facilitate compaction of the coal pile so that it can be stored for a long time, as well as minimizing losses from spontaneous combustion and early self-heating detection for safe coal storage.

Abstract

Slamet volcano is the second highest active stratovolcano in Java Island, it has a long volcanic history eruption event, the Baturraden Area is a tourism area in southern part of Slamet Volcano. Baturraden area is the part of Banyumas Regency and it took 30-60 minutes riding motorcycle from Purwokerto city. Our research is focused on studying the petrology, geochemistry, and geological history of basaltic lava on Baturraden Area mainly that formed a waterfall on its location, because there is no a researcher that study basaltic lava on Baturraden, we focus on petrology, and petrography and geochemistry of basaltic lava on Baturraden using XRF methods and focused on magma evolution of basaltic lava rocks on Baturraden Area. Stratigraphically basaltic rocks in Baturraden Area are a part of Slamet Lava 1(SL 1) and Slamet Lava 2 (SL 2). The mineral composition of SL 1 and SL 2 are including the phenocryst of plagioclase, K-feldspar, olivine, clinopyroxene, and opaque minerals, with plagioclase microlites and volcanic glass as groundmass. Plagioclase shows zoning and sieve texture. Seven rock samples are prepared for whole-rock major element compositions of the study, the SiO2 contents range from 48.13 – 49.17 wt.%. The K2O contents in all rock samples range from 0.78 – 1.56 wt.%. Geochemical data confirm that SL 1 and SL 2 are from same magma type that magma of SL  1 and SL 1 are influenced by fractional crystallization and magma mixing from new injection of more basaltic magma, as evidenced by the frequent changes in SiO2 content.

Abstract

The main task of PDAM Tirta Intan Garut Regency is to manage raw water into clean water for customers. The management of raw water supply in Bayongbong District for the community still relies on springs with a gravity system, deep well pumps and rivers. The flow of the Cimanuk River in Bayongbong District can be used to provide raw water. Four rainfall stations are used. Average rainfall is calculated using the Thiessen method. The raw water collection point does not have a automatic water level recorder (AWLR), so it is necessary to create a model to obtain the discharge at the collection point. The model used is the water balance model from F.J. Mock. Calibration of model parameters was carried out on observed discharge at Cimanuk-Bayongbong AWLR and Cimanuk-Bojongloa AWLR. To test the reliability of the model, NSE and RMSE values ​​were used. The NSE and RMSE values ​​in the Cimanuk-Bayongbong catchment area are 0.515 and 3.615 and Cimanuk-Bojongloa are 0.593 and 4.813. The results of the model parameter calibration are used to calculate the discharge at the collection point. The calibration result ​​at the collection site are exposed surface 50%, infiltration coefficient 0.5: recession coefficient 0.35: catchment area characteristic factor 10%; and soil moisture capacity 200 mm. The dependable flow is calculated based on Q90% probability, water availability in July, August, September and October is 0.078 m3/s; 0.025 m3/s; 0.035 m3/s; and 0.025 m3/s. Water availability in that month is smaller than the discharge requirement for the next five and ten years, namely ranging from 0.134 m3/s to 0.168 m3/s and 0.145 m3/s to 0,182 m3/s.

Abstract

This study explores the differences in perception between communities and practitioners regarding biopori-based water management technology in the context of flood management in Passeno Village, Baranti District, Sidenreng Rappang Regency, South Sulawesi Province, Indonesia. Employing a quantitative approach, the study involved 30 respondents, consisting of 27 members of farmer groups and 3 practitioners. Data were collected through surveys using structured questionnaires and analyzed using descriptive and inferential statistical techniques. The results indicated that communities rated the effectiveness and ease of implementation of biopori technology higher than practitioners did. The main obstacles identified were a lack of knowledge and government support, with proposed solutions including intensive investigations and government subsidies. Although no significant differences in perception were found between the two groups, this study emphasizes the importance of education, government support, and field experience in influencing the acceptance of biopori technology. The uniqueness of this research lies in its specific focus on biopori technology, the rare comparison of perceptions between communities and practitioners, and its systematic quantitative approach. Additionally, the study successfully identifies obstacles and practical solutions while encouraging better collaboration between communities and practitioners, thereby potentially providing significant contributions to policies and practices in water resource management in flood-prone areas.

Abstract

Various Neogene volcanic rocks associated with calcareous sediments compose the Southern Mountain located from Imogiri at Yogyakarta to Wonogiri at Central Java, Indonesia. The volcanic rocks are concentrated along the north side of the Mountains which was recognized as the Neogene magmatic arc of Java; Baturagung is part of them. The discussion focuses on the relationship between the volcanic features and its basin evolution. The methods were geological fieldwork including measuring sections and collecting samples, thin sections, XRF, AAS, and micropaleontology. More than 13 circular hogbacks, circular valleys, and domes are observed based on the SRTM image. The petrology observed pyroxene-rich basaltic volcanic rocks, dacitic volcanic rocks, andesitic volcanic rocks, coral-rich volcanic breccia. From the bottom to the top, its stratigraphy of the Kebo-Butak Formation that notes basaltic volcanic rocks, pumice-rich lapillistone, and tuff of Early Neogene (before P4-N6) with muddy sandstone above the basalts of N 5-6 (Lower Miocene). The Semilir Formation consists of pumice-rich and dacitic tuff. Andesitic volcanic rocks of the Nglanggeran Formation with inlayer of marl of N 13-14. In the volcanic rocks trace elements show REE-rich (84-140 ppm), higher mobile elements of Sr (~480-602 ppm), medium Rb (22.2-23.7 ppm), and medium La (12-21 ppm), and wide range of immmobile trace elements of Nb ~2.7-7.9 ppm, Zr ~53-171 ppm, P ~840-1300 ppm, higher Ti (4400-4900 ppm), and higher Vanadium (V) of 92-302 ppm. Plot TiO2 vs. Al2O3 into the volcanic rocks indicates those were volcanism within plate boundaries. Plot Ta/Th vs Th/Hf shows continental extensional volcanism to continental arc margin. Plot Nb/Zr vs. Th/Zr explains the transitional zone to continental arc volcanism. The spider diagram shows Rb, Ce, P, Ti, Sr, Zr, and Y strongly metasomatized as a result of the upper continental arc. The chondrite normalized REE shows negative trends for Tb, Tm, Lu, Sm, and Eu and positive trends for Ce, Gd, Zr, and Y, which indicate superimposed volcanism under a submarine environment during the Neogene Period. Stratigraphic sections inform were periodically active volcanism. The Kebo-Butak Formation was formed by multiple volcanoes, some of which were active simultaneously while others were not, though both fall within the Early Neogene age range. Similarly, the Semilir and Nglanggeran Formations were also formed by volcanic activity from several volcanoes that were active at different times and overlapped with each other.

Abstract

The study area is located in Semarang, representing a coastal and industrial zone where groundwater exploited as main water resources. Seawater instrusion has been identified as a significant issue in coastal regions due to its impact on groundwater quality. The study was conducted using groundwater data from deep aquifers (bore wells). The physical and chemical contents were analyzed to determine the groundwater characteristics and identify the seawater intrusion. Piper and Durov diagram were used to determine the hydrochemical facies and the main processes that influence the chemical content in groundwater. The Cl vs Na/Cl ratio diagram were used to identify the source of Cl and Na ions, determining weather the ions originate from anthropogenic activites or seawater intrusion. The Physical properties of groundwater show that the groundwater in the study area is divided into 2 group: a freshwater group with TDS value <1000 mg/L and a brackish water group with TDS value ranging from 1000 – 4006 mg/L. The results of hydrochemical analysis indicates the occurrence of seawater intrusion in some locations. Seawater intrusion in the study area mainly occurs in the northern part of Semarang city which relatively near with coastal line. The seawater intrusion also occurs in the eastern part of study area (Demak) with a more severe level, reaching areas at a further distance from coastal line compared to Semarang city.
