Abstract

The Nanggulan Formation has a very narrow spread compared to other formations. In Kulon Progo formation has the oldest age in the Middle Eocene-Early Oligocene. This research is located on the Songgo River at coordinates 07 ° 44 '00.7 "S - 110 ° 12' 17.5" E to 07 ° 44 '15.3 "S - 110 ° 11' 53.6" E. This research intends to reveal the types of depositional environments that are developed along the Kali Songgo track using measured stratigraphic log analysis. The stratigraphic log's interpretation indicated lithofacies, facies associations, and the depositional environment. The lithofacies that compiled the research location based on lithological data and sedimentary structure can be divided into ten types: a.Bedded claystone, b.Laminated sandstone, c.Cross-bedding sandstone, d.Bedded sandstone, e.Bedded siltstone, f.Massive claystone, g.Laminated siltstone, h.Graded-bedding sandstone, i.Wavy sandstone, and j.Massive sandstone. Three facies associations are recognized based on the lithofacies grouping: 1. Mud flats, 2. Mixed flats, and 3. Sand flats. The depositional environment that developed along Kali Songgo track was Tidal flats.

Abstract

Gunung Kidul Regency, especially Ponjong District, is known as a barren or dry area, and always suffers from a lack of water to meet domestic needs. The Wonosari area and its surroundings have relatively productive aquifers locally. The purpose of this study was to determine the type, location, depth, thickness, and subsurface 3D modeling using the geoelectric method of Dipole-dipole and Schlumberger configurations. Based on the results of surface data, there are two springs in Grogol Hamlet which are interpreted as appearing because there are cracks in the subsurface rocks and springs in Sumberejo Hamlet which are interpreted as their appearance due to the controlling factor of the Sumberejo Sinistral Fault. Meanwhile, geoelectric data analysis shows the presence of rock layers as a confined aquifer in Garon Hamlet at a depth of 63-87 meters and in Dusun Sumberejo at a depth of 55-68 meters. Key words: aquifer, dipole-dipole, geoelectric, Ponjong, schlumberger.

Abstract

Characterization and potential of sand deposits in the Kabuh Formation at Mlale Region because gray-black sand deposits were found with magnetic properties, interpreted as iron sand. The purpose of this study was to determine the characteristics and potential of iron sand deposits. The research methods used are detailed observations, rock sampling, laboratory activities for petrology and XRF geochemical analysis, studio activities for data interpretation. The geological condition shows 1 – 3 meters gray-black sand deposits with +20 meters layer. The petrological analysis shows the grain size fine – coarse sand, slightly rounded – angular shape, opaque minerals is 66% megascopically and microscopically 23%. Sand deposits are interpreted as alluvial placer deposits from Nglanggran Formation and Kebobutak Formation at the Southern Mountains Zone, as well as the Anggota Banyak Kalibeng Formation and Pucangan Formation from Kendeng Zone. The enrichment factor is from magnetic minerals on source rock and the basin topography, but the destruction factor is not well developed. XRF geochemical analysis showed 4.41% Fe content and 7.71% hematite (Fe2O3) content. This grade can’t be processed and refined as metal mineral. Increasing the value can be better by filtering and separation.

Abstract

The Nanggulan Formation as the oldest formation in the Kulon Progo Mountains is not only exposed in a type location in the Nanggulan area, Kalibawang. However, in the western area of ​​the Sermo Reservoir, precisely in the hills around the Kokap, the Nanggulan Formation is found in several places. The existence of the Nanggulan Formation around the Sermo Reservoir is suspected to have triggered the occurrence of ground movements in this area. The purpose of this research is to map the ground motion. The purpose of the study was to determine the potential for ground motion in the study area. The research area is included in the southern Kulon Progo Dome Mountain Zone. This ground motion zoning mapping was carried out based on the AHP (methodAnalytical Hierarchy Process) using the weighted values ​​of four parameters. The parameters used are slope, lithology, land use and rainfall. The results of AHP processing using Arc GIS software produce a landslide susceptibility zoning map which is divided into 5 classes (very low, low, medium, high and very high). Based on the results of mapping using the AHP method, the most vulnerable area is Hargowilis Village which is composed of claystone lithology from the Nanggulan Formation.

Abstract

Debris flow is one type of mass movement that occurs where a combination of loose soil, rock, organic materials, air, and water moves down to a slope. Debris flow usually occurs due to intense surface water flow and heavy rainfall, which erodes and mobilizes loose soil or rock on steep slopes. In the last decade, debris flow disaster have occurred in Lombok Regency which caused many casualties and infrastructure damage. The method used in this modeling is generated from the processing of the Digital Elevation Model (DEM) data which is correlated with several parameters such as volume, friction, etc. Furthermore, the parameters determined are simulated using the RAMMS application. The results of this modeling are numerical data and zonation maps of debris flow prone areas. This Research is expected to be an effort to mitigate debris flow disasters around the Palung watershed, Lombok Regency, West Nusa Tenggara Province. Keyword : debris flow, modeling, RAMMS, Palung Watershed.
