Abstract

Bener District, Purworejo Regency, Central Java, Indonesia, located in the Kulon Progo Mountains can be classified as a high-risk area. Many experts and researchers have studied landslides, but there has been little research on rock slope kinematics. In fact, when such a rock slope is unstable and poorly monitored, it has the potential to endanger the community or facilities at the adjacent site. This is why slope kinematics research is required. To complete this study, rock kinematics analysis using the Markland method was performed on six representative slopes. The assessment results show that Kaliwader slope A, Kaliwader slope B, and Argosari slope each tend to collapse with wedge failure, Kaliwader slope D and Wadas slope have the potential for wedge failure and planar slide, but Kaliwader slope C does not. Despite their steep inclination, slopes that are likely to fail are strongly related to the presence of geologic structures, particularly joints, and faults, at the sites. The findings of this study will be helpful in the development of landslide vulnerability zones in the context of disaster mitigation.

Abstract

The geological structural patterns and hydrothermal alteration zones of Atauro Island, Timor-Leste, which are influenced by the collision mechanism between the Banda Arc and the Australian Continent, are the subject of this study. The study identifies fault types and alteration zones through stereographic analysis. It indicates the possibility of mineralization in the area. Four alteration zones were identified in this study: argillic, Propylitic, calcosite, and geotite. The analysis results show that left-striking and normal faulting were essential in forming these zones. The mineralization zones, mainly chalcopyrite and chalcocite, are related to the north-northeast trending left horizontal Fault. In addition, this study suggests additional research that includes mineralogy, geochemical, and geophysical analyses to understand more about the characteristics of hydrothermal alteration zones and possible mineralization on Atauro Island. The results of this study are expected to improve our understanding of mineral resources in the region, and it is suggested that this information be considered by authorities responsible for the management of potential natural resources on Atauro Island, Timor.

Abstract

The research location is located in Paningkaban area and its surrounding areas that included in the areaof Gumelar Subdistrict, Banyumas Regency, and Central Java Province. The objective of the researchwas to show the presence of any structural geology control on research area that affect the distributionpatterns of quartz vein and gold/ore mineralization.The methodology in this research begins with data collecting process, which this preliminary data is thenbeing compiled to determine the next phase of the study. This study covers the geomorphology,stratigraphy, any structural and alteration mineralization observation. The geomorphology of the studyarea composed of the four original forms: volcanic, structural, karsts and fluvial form. The stratigraphycomposed of seven unclassified litho units and two litodem, namely (from old - young): Halang volcanicbreccias unit, Halang sandstone unit, Kumbang andesite lava unit, Tapak volcanic breccias unit, Tapaksandstones, unit Tapak limestone unit, alluvial deposits, and andesite intrusion.Hydrothermal alterations formed in the research area are carefully grouped into three types of alterationzoning and they are argillic alteration, propylitic alteration, and sub-propylitic alteration. Themineralization then is carefully classified as pyrite (FeS2), chalcopyrite (CuFeS2), galena (Pbs), bornite(Cu5FeS4). The macroscopic analysis of the structure in the study area based on the alignment of allegedtraces of the geological structure in the form of fault, or directions of the fold axis alignment, obtainedthe general alignment directions trending N 305° E (NW - SE), and N 055° E (NE - SW).In the research area, the mineralization process is controlled by geological structure such as fault andjoint. The appearance of the mineralization is abundant and can be found many fulfilling the joint zonemainly shear joint trending Northeast - Southwest and Northwest - Southeast, the direction of jointsharpness measured in the field relatively trending North - South. This study will emphasize on themeasurement and detailed analysis to know more about the gold mineralization process and otherminerals controlled by structures patterns. The structural control analysis can really be a good helpinghand in locating the mineralized areas because basically the activity and geological structure controlprocess are corridor for magma and the its rest compound that brings minerals, so the methods ofmineral ores exploration by structure control can be used in determining ore gold mineralized depositsprecipitate on gold deposits system and other minerals on a different area.Keywords: lithostratigraphy, structure, zone of opening, zone of alteration, mineralization, metalminerals

Abstract

Water is the primary needs for the livelihood of people in Gebang hamlet, Girisuko village, Gunung Kidul Regency, Special Region of Yogyakarta. Gebang is a hamlet in Panggang district, Gunug Kidul Regency, of which water supply is insufficient to meet the needs. There are 170 households with an average of 4 lives each, thus about approximately 680 people don’t have sufficient water supply. Water supply to the hamlet is constrained by the pumping ability.The neighborhood rely on overflowing raw water in high rainfall season that is channelled through pipe to the certain water tank prepared as reserves for dry season and few of them had used water from a cave. However, the pump is now broken so in a long dry season they need to buy water using tank truck. Based on the observation, this research planned to design water pump arrangement with high capacity so water can easily be channeled to the water tank and distributed to people in the neighborhood.The material absorbed in karst medium is related to each other, between organic (coliform parameter) and anorganic material (TDS parameter). The water puryfying process was conducted in laboratory and another process engaging gravity sand filter was chosen using zeolith with thickness of 40-50 cm that is able to decrease TDS from 232 – 268 ppm up to 180 ppm.

Abstract

Household waste, especially plastic, styrofoam and used tires, is a problem for the community because it reduces the quality of the environment. In addition, another problem faced by the community is the increase in household expenditure from consuming fuel for cooking. The community service team tries to overcome both of these problems by implementing waste-to-fuel processing technology. Community service activities include training, mentoring, and providing facilities for processing waste into environmentally friendly fuel. The activity was carried out at the Surolaras Waste Bank, Yogyakarta City. The benefits that are felt are reduced waste, fuel products that can be used for household needs, reduced household expenses, and a well-preserved natural environment.

Abstract

The Grindulu River in Pacitan is one of the areas that exhibits manifestations of hydrothermal alteration and metal mineralization. However, the valuable metals found are relatively low, making it less economical to produce. This condition opens up other opportunities by utilizing the area as a natural laboratory for geological education and sustainable geotourism development. This study evaluates the potential for hydrothermal mineralization-based geotourism through geosite assessment. The study area comprises the Watupatok Formation and the Arjosari Formation, which show silicic, argillic, and propylitic alteration zones. The research methods include geological mapping, rock sampling, petrographic analysis, XRD, FA-AAS, and geosite assessment using the Kubalikova method, covering scientific, educational, aesthetic, and value-added aspects. The results show the presence of mineralization in the form of pyrite, chalcopyrite, sphalerite, and galena, with low levels of valuable metals (Au, Ag, Cu, Pb, Zn). Nevertheless, all three segments of the Grindulu River possess significant geosite value for educational and conservation purposes, with segment 2 considered the most ideal due to its superior accessibility and educational value. This study concludes that the Grindulu River is more appropriate for development as a sustainable geotourism destination based on conservation and geological education rather than mining exploitation.
