Karya Murni is one of the areas in the northern arm of Sulawesi that has been tectonically influenced. Tectonic processes have implications for the formation of rocks and geological features that have the potential to be developed into geodiversity sites. The development of geological features as a geodiversity site in aspiring geopark Gorontalo can protect valuable geological features from frequent degradation. This research aims to analyze and conduct quantitative assessments of geological diversity in Karya Murni, Gorontalo. The research method used is field observation, laboratory analysis, and geodiversity assessment. Field observations included observing landform, collecting rock samples, and measuring geological structures. Field observations were also carried out to observe aspects of the geodiversity assessment which included science, education, tourism, and risk degradation. Laboratory analysis consists of geomorphological analysis, petrographic analysis, and geological structure data analysis. Geodiversity assessment uses the Geological Survey Center of Indonesia assessment. The results suggest that the geomorphology of the study area can be divided into four geomorphic units-the volcanic hills, denudational hills, Karst hills, and fluvial plain units. The stratigraphy of the research area is divided into four units from the age of the early Eocene to the Holocene-the andesite lava, volcanic breccia, reef limestone, and alluvial deposit units. The geological structure of the study area is a trending northeast–southwest to northwest–southeast. Active faults at the location of the study area consist of the Apitalawu normal fault. At recent states, generally geosites of the Karya Murni have moderate scientific values, the low educational and touristic values and high risk of degradation. The geodiversity potential of the research area can be utilized for further research and education.

Gerbang Oluhuta Journey.

Information and communication technology has become a necessity in all aspects of life, including the tourism sector. For this reason, the team of PHP2D created an innovative application for edu-geotourism in Oluhuta Village. The method used in the community service includes the initial planning, execution stage, monitoring and evaluation stage. The results showed the application was very functional and in accordance with the edu-geotourism concept, thus made the implementation of the edugeotourism concept in Oluhuta Village more optimal, especially in helping the surrounding community to promote and market tourist attractions in Oluhuta Village. The public and visitors could use the mobile app marketing to recognize the potential exists and available local products in Oluhuta Village. On the other hand, the obstacle found that poor internet access in Oluhuta Village caused some visitors got difficult to download the application, therefore it is designed to be used offline and the download process should be done before arriving in Oluhuta Village.

Hydrogeology field work 2015 was held at four location in Gorontalo. The field work was followed by students of class '12 (Geohazard) and students of class '13 (Geobaper & Geoamnesia) at Geological Engineering Major, Earth Science and Technology Department, Universitas Negeri Gorontalo.

Field work includes the identification of geothermal hydrogeology in the field work location. Students observed the morphology, stratigraphy, water table, and physical-chemistry of hot springs in field work location. This field works are supervised by Intan Noviantari Manyoe, S.Si., MT (Lecturer).

Daerah penelitian secara administratif berada di Kecamatan Boliyohuto, Kabupaten Gorontalo, secara fisiografi daerah penelitian berada di lembah paguyaman yang didominasi oleh batuan gunungapi dan endapan danau. Penelitian ini bertujuan untuk mengetahui geologi bawah permukaan daerah Bongonggoayu. Metode yang digunakan dalam penelitian ini menggunakan geolistrik konfigurasi Wenner-Sclumberger. Hasil penelitian geologi bawah permukaan daerah penelitian menggunakan geolistrik Wenner-Schlumberger terbagi atas 4 lintasan berdasarkan pengolahan Res2dinv dan rockword terdapat beberapa lapisan litologi berdasarkan penampang 2D bawah permukaan dimana didominasi oleh lapisan kelompok batupasir, lempung dan pasir kerikil. Kemudian terdapat anomali yang kemungkinan besar pada anomali ini terdapat pengaruh struktur dengan arah barat laut-Tenggara pada lintasan 1 dan lintasan 4.

Data acquisition.

Exploration Geophysics field work 2015 was held in Pancuran, Bone Bolango Regency, Gorontalo. The field work was followed by students of class '13 (Geobaper & Geoamnesia) at Geological Engineering Major, Earth Science and Technology Department, Universitas Negeri Gorontalo.

Field work includes the identification of subsurface in the field work location using geophysical instrumentation. Students were given the ability to use Resistivity Meter. They also observed the morphology, stratigraphy, and physical-chemistry of hot springs in field work location.

This field works are supervised by Intan Noviantari Manyoe, S.Si., MT (Lecturer), and Andri Saputra Jusuf (Assistant).
