Geotourism emphasizes the beauty, uniqueness, rarity and wonder of natural phenomena as an impetus for the development of geology-based tourism. The many variations in geological aspects fulfill the potential geodiversity value in the area. The aim of this research is to identify and assess the potential for geodiversity in Oluhuta Village. The research location has coordinates 0° 25' 0" - 0° 27' 0" N and 123° 8' 30" - 125° 10' 30" E. There are several research methods used in the form of field observations, laboratory research, and processing studios. The geological data obtained includes lithology, geomorphology and assessment of geodiversity aspects. The results of the research show that the location of the research area has lithology namely reef limestone and geomorphology namely reef terrace plains. The research area has a site called the Lautan Terangkat Site. This site has geological components including rocks and natural landscapes. Lautan Terangkat site have several assessment criteria with a total number and scientific assessment classification. Scientific value assessment is classified as medium, the educational value assessment is classified as high, tourism value assessment is classified as medium, and the assessment of degradation risk value is classified as low.

Indonesia has very diverse and unique rocks that have the potential to become a geological heritage. Based on the existing potential, an integrated management system is needed so that it can be utilized for the welfare of the community, one of which is a geopark. Gorontalo has a rock distribution consisting of several formations, one of which is the Tinombo Formation which is the oldest formation. In this formation there is red limestone which has great potential due to its rarity so that it can be developed into a site in the development of a geopark in Gorontalo. The purpose of this research is to conduct a geosite assessment of geological features in Boalemo Regency as a basis for developing geotourism in Boalemo Regency, Gorontalo. The research site is located in Dimito Village, Wonosari Subdistrict and Lahumbo Village, Tilamuta Subdistrict, Boalemo Regency, Gorontalo Province. The methods used in this research are lithological analysis, Geochemical analysis and geosite potential analysis using the technical guidelines for geological heritage resource assessment by the Geological Survey Center. The results showed that the red color-controlling minerals in limestone are hematite and rodoxite, the red color-controlling chemical elements in limestone are SiO2, MnO, Fe2O3, Sr and CaO. The results of the assessment of geological features explain that the Wonosari Red Limestone Site and the Tilamuta Red Limestone Site are included in the medium category. Geosite Red Limestone can be developed as an object of study in the field of education by utilizing natural laboratories for the development of geoparks in Gorontalo.

Sulawesi or Celebes is located in the central part of the Indonesian archipelago which has interesting geological potential to be developed. One of this interesting area is known as Ambang volcano area. Ambang volcano is one of the active volcanoes in North Sulawesi. Administratively, the research area is located in Bongkudai Baru Village, Modayag sub-district, East Bolaang Mongondow district, mapped at coordinates N 0°45'58.89'' and E 124°24'13.04''. This study is aimed to analyze volcanic geomorphological units using satellite imagery and surface geological mapping. The results showed that the geological conditions of the study area consist of 4 lithologies i.e volcanic breccia, andesite, agglomerate and sandstone rocks. Based on the morphographic and morphogenetic analysis of the study area which refers to the Van Zuidam and Verstapen 1985 classification, the study area is divided into five landforms i.e fumarole and solfatara ambang volcanic, ambang volcanic cone, plains and fluvial slope feet of ambang volcano, denudational hill ambang volcanoes and lake units.

Tatanan geologi dan tektonik yang kompleks menjadi penyebab keterdapatan banyak batuan intrusi untuk membentuk berbagai tipe cebakan mineralisasi pembawa mineral ekonomis. Prospek Daerah Gadung, Kabupaten Buol, Provinsi Sulawesi Tengah memiliki potensi yang besar karena kondisi geologinya yang kompleks, namun penelitian di daerah ini masih sangat kurang dan hanya menggunakan metode stream sediment dalam pengambilan data sehingganya diperlukan adanya penelitian yang terbaru dan detail. Metode yang dilakukan dalam menyelesaikan penelitian ini berupa metode pemetaan geologi semi detail dan channel sampling yang terdiri atas observasi litologi, struktur geologi hingga geomorfologi. Pengambilan sampel batuan untuk dianalisis petrografi dan mineragrafi sebagai data analisis pendukung. Satuan geomorfologi berupa pegunungan aliran lava Gadung dan perbukitan intrusi tinggi Gadung yang dimanfaatkan oleh penambang tradisional. Satuan litologi berupa vulkanik andesit, intrusi monsonit, intrusi monsodiorit, intrusi breksia, intrusi diorit porfiri, dan breksia hidrotermal yang paling banyak keterdapatan mineralisasi ekonomis. Struktur geologi berupa sesar naik dekstral Anoa dan sesar sinistral normal Ladelli yang menjadi jalan bagi intrusi naiknya fluida hidrotermal. Dari hasil penelitian dapat disimpulkan bahwa daerah ini memiliki potensi cebakan mineralisasi karena kehadiran bodi breksia hidrotermal yang besar dan keterdapatan kontrol struktur berupa dilatational jog, dan kehadiran kuarsa vein berupa mineralisasi sulfida pada litologi intrusi monsonit dimana litologi ini menjadi litologi yang mendominasi pada daerah penelitian.

Geomorphological research is urgently needed to be carried out in areas with geothermal potential such as in Talumopatu. Geomorphological analysis was chosen to complete the data in the early stages of the geothermal exploration of the study area. The purpose of this study was to determine the geomorphological characteristics of the study area. This study uses image interpretation methods and field excursions to observe the morphology of the study area. The stages of data processing use software applications based on Geographic Information Systems (GIS). The Geomorphological analysis consists of analysis of morphography, morphometry and morphogenesis. The analysis results are then compiled to produce a geomorphological map that refers to the van Zuidam classification. In accordance with the results of the analysis, it can be concluded that the geomorphological condition of the study area is divided into three parts, namely the Alluvial Plain Unit, Peneplains Unit, and Residual Hills Unit.
