Pacitan district have an interesting anomaly. Every time mostly impacted by disaster especially landslide. Landslides in their various forms are common hazard in mountainous terrain, especially in seismically active areas and regions of high rainfall. Landslides are one of the most common natural hazards in the Southern Range East Java terrain, causing widespread damage to property and infrastructure, besides the loss of human lives almost every year. The aim of this study predicted the potential landslide using Weight of Evidence Method. The geological data used lithological data, structural data, contour data and, alteration. Results from this data analysis are six evidence maps, such as NE-SW lineament, NW-SE lineament, host rock, heat source, kaolinite alteration and iron oxide alteration maps. The geophysical data analysis the distribution of rock density to interpretation the landslides. Evidence maps were analyzed by weight of evidence methods to result in favorable maps where the validity was tested using conditional independence (CI), the pairwise and overall tests. Then, the analyses produced a posterior probability map of the landslide. Posterior probability map (mineral potential maps) was validated by checking field. Posterior probability map (after validation) or favorable map predicted approximately favorable zone and non-favourable zones. Favorable zones of Potential Landslide Hazard Zonation, are divided into three classes. They are high-potensial hazard, moderate hazard and low hazard.   Keywords: Pacitan, GIS, Weight of Evidence, Landslide

Study of groundwater types using the Vertical Electrical Sounding (VES) method in 'Martani Field’ Ngemplak District of Yogyakarta was done by carrying out eight measurement points to look for groundwater potential. This area is an area on the southern slopes of Mount Merapi which is included in the Yogyakarta Groundwater Basin. The type of lithology is identified based on the measurement of its resistivity value so that there are several types of lithology, namely Breccia (110-670 Ωm), Clay (1.99-10.12 Ωm), Sandstones (17.06-56.82 Ωm) and andesite lava (688-1657 Ωm). The bottom of the aquifer in this basin is composed of rock formations that are impermeable or semi impermeable which are non-aquifer, namely by Breccias, Clay and Andesite Lava. The existence of sandstones that act as aquifers is found near the surface at a depth of <25 m and at a depth of about 60-100 m below the surface so that it is divided into two categories, namely shallow groundwater and deep groundwater.

AbstrakSurvei potensi sumber daya geologi di Daerah Gunung Wungkal Yogyakarta yang didukung data resistivitas telah dilakukan. Hasil korelasi data menunjukkan adanya sumber daya berupa bahan galian C yang merupakan hasil lapukan intrusi batuan beku yang kemudian menghasilkan lempung-lempungpasiran (2,71-5,36 Ωm), pasir-batupasir (7,59-45,15 Ωm), lapukan batuan diorit atau breksi andesit (91,49-296,48 Ωm). Ketebalan batuan-batuan tersebut sekitar 225-231 meter berdasarkan penampang peta geologi di permukaan dengan arah sebaran dari Barat Laut hingga Tenggara. Morfologi daerah tersebut terdiri dari perbukitan yang merupakan perbukitan intrusi terdenudasi dan dataran alluvial dengan proses pelapukan serta alterasi yang intensif (alterasi argilik). Litologinya merupakan intrusi Diorit yang kaya akan mineral plagioklas, Breksi Andesit dan endapan Alluvial (endapan Merapi Muda). Adanya perselingan lapisan pasirbatupasir (permeable) dengan lempung hingga lempungpasiran (impermeable) pada model resisitivitas yang didukung informasi sumur warga, didentifikasi sebagai akuifer airtanah yang relatif dangkal. Dugaan keterdapatan mineralisasi dan logam berharga juga dianalisis dari sampel-sampel singkapan batuan dan analisis model resistivitas namun dibutuhkan uji laboratorium lebih lanjut. Kata kunci: gunung wungkal, data resistivitas, sumber daya geologi PendahuluanGunung Wungkal merupakan suatu daerah berbentuk perbukitan dan daratan yang berada di Kecamatan Godean Kabupaten Sleman Yogyakarta. Studi geologi dan geokimia pernah dilakukan oleh peneliti terdahulu yang mengkaji umur, material maupun membahas potensi geologi positif maupun negatif di daerah tersebut. Bronto (2014) [1] menyatakan bahwa Daerah Godean memiliki morfologi perbukitan terisolir akibat pengaruh kontrol denudasional pada batuan beku dan gunungapi. Hasil longsoran raksasa dari Gunung Merapi dan endapan kuarter fluvio-vulkanik membentuk monfologi daratan di sekeliling daerah tersebut. Sedangkan sisa pelapukan dari erosi permukaan menghasilkan tinggian di daerah Godean yang berupa dataran agak bergelombang akibat dari pengendapan material pekat.Bronto (1999) [2] menginterpretasi bahwa Gunung Wungkal merupakan bagian dari gunungapi purba yang berumur Miosen dan seumur dengan jajaran Pegunungan Selatan bagian utara, yaitu antara 11,3-17,2 Jtl. Daerah Godean sendiri memiliki Vulkanisme dan magmatisme yang serupa dengan Gajahmungkur (Wonogiri) dan Menoreh (Magelang), yang disertai tahapan mineralisasi pada bagian fasies pusat erupsinya. Berdasarkan informasi ini, maka dimungkinkan sumber potensi bahan galian industri maupun kandungan logam berharga diperkirakan cukup melimpah.Pengaruh dari pola tektonik berupa sesar turun berarah Barat-Timur dan sesar berarah Selatan-Baratlaut menyebabkan anomali di Godean dan Banguntapan dan adanya perlapisan sedimen diduga karena intrusi (Barianto, dkk., 2009 dalam Winardi, dkk., 2013. Rahardjo, dkk (1997) [4] menyatakan bahwa batuan tertua di daerah penelitian berumur Eosen yang termasuk Formasi Nanggulan (Teon). Formas...

Mompreneur village, which is currently established under the guidance of the HMTG "GAIA" Village Development and Empowerment Program Team (P3D), has succeeded with the traditional drink product "seruputan" which has been able to be sold outside of Yogyakarta. However, the current problem is that the production of the product is constrained due to the lack of raw materials for the main spices. On the other hand, there are residents' land that has not been used. The purpose of this service is to increase the spice land by utilizing the land of residents who are not yet productive. As a result, the creation of a “sruputan” spice garden together with the assisted residents was achieved according to the target by planting various spices that sparked business ideas in innovating various flavors of 'sruputan' products and other forms of slurry products. Keywords: Spice Garden,  traditional drinks, village empowerment, putat wetan
