Geosite Identification in Karangbolong High to Support the Development of Karangsambung-Karangbolong Geopark Candidate, Central Java

Geopark is an area that has an outstanding geological evidence, including archaeological, ecological and cultural values in which local people are invited to participate in protecting and enhancing the function of natural heretage. Its sustainable development concept has proven to increase economic and conservation benefits. Geopark introduces the earth's heritage, protected areas, geo-development, economic development and implementation of various science and technology. Geoparks have unique geological, cultural and biological that can be utilized for conservation and geotourism. Indonesia has 2 global geoparks, 4 national geoparks and 15 geopark candidates. Karangsambung-Karangbolong area is one of the geopark candidates which is a subduction zone that underwent an uplift and now is dominated with conical hills karst. The Kebumen local government is preparing a master plan for Karangsambung Geopark except Karangbolong, and LIPI is supporting the scientific studies. To initiate the development of Karangsambung-Karangbolong Geopark, an integrated geosite identification has to be done. Field observation of geodiversity, bio diversity and culture diversity, followed by rating of geosite based on scoring method using weighting 3 for geodiversity, 2 for biodiversity and 2 for culture diversity. Geosite of Karangbolong High includes geosite of karst-nonkarst morphology of Wanalela Hill and Tugu Village. Cave geosites are Barat, Petruk and Jatijajar caves. Beach geosite include Lampon, Menganti, G. Hud, Logending, Karangbolong and Karangagung beaches. Very good geosites are Petruk cave, Hud hill and Barat cave. Good geosite includes Lampon, Menganti, Karangpamuran, Pelus, Jatijajar, Wanalela, Logending and Karangbolong. Geosite at Karangbolong High provides good support for the development of Karangsambung-Karangbolong Geopark. IOP Conf. Series: Earth and Environmental Science 118. Hal. 1-12
