Abstract

Pathuk Hill is located abouth 15km eastern from Yogyakarta City. Pathuk Hill is elongatedhill (escarpment) trending NE-SW stricking and formed the steep slopes to the north-west.An average height of a Pathuk Hill between 200m-250m above sea level. This hill arecomposed by interbadded tufaceous sandstone and tuff of Semilir Formation in the lowerpart. Conformity above of Semilir Formation is volcanic breccia of a solid NglanggranFormation. In the top of the Pathuk Hill we can see the exotic view of Yogyakarta City in thewestern, Merapi Vocano in the north-western and sunset in the western in the afternoon. Inthe Pathuk Hill resort will be development of the big resort as the gateway to the WonosariCity. This area would be developed as a torism object between Yogyakarta City andWonosari City.Keywards : Pathuk Hill, slope tability, resort, view, torism object.

Abstract

Wonocolo is located in Bojonegoro District who one of geosite of 20 geosite point to support The Petroleum Geoheritage Bojonegoro. Wonocolo is area’s of Asset-4 Pertamina Cepu. Wonocolo area is a good interesting to develope as Geological Tourism object of old well, because in this area to exploitation of hidrocarbon with tradisional system use  car’s mechine and with rig of Jati Threes. The deep of reservoir Wonocolo only about 200-400m from survace. The many rig to explorer hidrocarbon tradisionally, so like in the Texas. So this study to make the Geological Tourism Object of Wonocolo Old Well with economy improvement of Wonocolo Community, Bojonegoro, East Java. Things that can be developed there among other: 1. Tracking get the jeep, tracking trail and tracking a bicycle, 2. Wells pilot; 3. Places beautiful to photograph a selfi, 4. The existence of transit equipped with photographs wonocolo from year to year of fossils, and Wonocolo’s maket, 5. The development of its tourism education in all quarters. This intended to give addition to entrepreneurs mining with the tourism and finally as an alternative income if later oil in wonocolo up.

Abstract

The Meratus Mountain in South Kalimantan Province have many geosites variations as geodiversity of National Meratus Mountain Geopark with theme the oldes ofiolite in Indonesia. Meratus Mountain was formed since 200-150ma from collision interaction of eastern part of Sunda Land with Pasternoster Continent who striking towards NE-SW in South Kalimantan Province. This mountain bordered Asam-asam Basin inthe eastern and Barito Basin in the western. The process of multideformation process formed the Meratus Mountain and exposed the ofiolite complex in Indonesia, aged between 200-150 million year ago. This rocks include : dunite, peridotite, pyroxenite, gabro, pillow basalt and chert.

Abstract

Engineering geology or Geotechnical is the application of geological science in engineering practice for the purpose of ensuring that geological factors affecting the location, design, construction, operation and maintenance of engineering works have been properly identified and taken into account. Engineering geology research can be carried out during the planning, environmental impact analysis, civil engineering design, optimization engineering and construction stages of public and private projects, as well as in the post-construction and project investigation stages. Engineering geology research is carried out by a geologist or an educated engineering geologist, trained professionals and has the ability to recognize and analyze geological hazards and adverse geological conditions. The whole purpose is to protect life and property from damage as well as solutions to geological problems. Geological observations made in the form of geological structures in the form of joints and faults are very important parameters carried out in the planning stage of a development because it is very influential in the short, medium and long term stability of a civil building. Detailed measurements and mapping of the intensity level of geological structures will be able to assist engineering geologists in making recommendations for a civil construction project. Geological engineering study of the Ajibarang area and its surroundings, especially in the area of PT.development project crusher and conveyor. So that it will get good slope safety and can be used as the basis for the development of the crusher and conveyor at PT. Semen Bima.
