Geomorphology field work 2015 was held at Otanaha Castle, Gorontalo. Otanaha castle was built at the top of the mountains so the landform can be observed clearly The field work was followed by students of class '15 at Geography Education Major, Earth Science and Technology Department, Universitas Negeri Gorontalo.

Field work includes the identification of landforms in the field work location. Students were given the ability to use compass, read a map and plot position on a map.

This field works are supervised by Intan Noviantari Manyoe, S.Si., MT (Lecturer), Febryant Masulili (Assistant Coordinator), Nurfauziah Kadir (Vice Koas), Alifia Widya Warapsari Badaru (Assistant), Mohamad Mokoginta (Assistant), Umar Zulkarnain Bakkar (Assistant), Fajri Fitrah Fidiyanto A.

Secara administratif wilayah penelitian terletak di Desa Keramat dan sekitarnya, Kabupaten Boalemo, Provinsi Gorontalo. Daerah penelitian tersususun oleh batuan terobosan dari formasi Batuan Gabro (Teog), Formasi Batuan Granodiorit Bumbulan (Tpb) dan Formasi Aluvium (Qal). Kondisi geologi daerah penelitian sangat kompleks sehingga menarik diteliti karena belum pernah dilakukan penelitian secara detail. Tujuan penelitian yang akan dicapai adalah mengetahui karakteristik mineralogi dan tekstur serta proses terbentuknya batuan dasar berdasarkan data pemetaan geologi dan data petrografi. Metode penelitian yang digunakan untuk mencapai tujuan penelitian tersebut terdiri dari survei geologi lapangan, penelitian laboratorium, dan pengolahan studio. Metode observasi lapangan adalah metode yang berfokus pada pengamatan kondisi geologi di daerah penelitian. Kemudian data-data yang diperoleh dianalisis menggunakan metode penelitian laboratorium berupa analisis petrografi dengan sayatan tipis. Hasil penelitian menunjukkan bahwa Morfologi daerah penelitian terbagi menjadi 2 satuan yaitu satuan perbukitan rendah struktural dan dataran aluvial. Stratigrafi daerah penelitian dibagi menjadi 2 satuan diurutkan dari tua ke muda yaitu satuan gabro, satuan granodiorite dan satuan endapan aluvial. Struktur geologi yang bekerja pada daerah penelitian berupa kekar gerus yang memiliki arah barat laut-tenggara hingga timur laut-barat daya. Berdasarkan hasil analisis petrografi yang telah dilakukan maka diperoleh hasil karateristik batuan gabro sebagai batuan dasar pada formasi gabro adalah berwarna putih kecokelatan (PPl), berwarna abu-abu hingga orange (XPL), hypokristalin, ukuran kristal (1-3 mm), bentuk dan hubungan antar kristal subhedral. Tekstur umum ekuigranular faneritik dengan komposisi mineral penyusun batuan yaitu plagioklas, K-feldspar, biotit, piroksen, mineral opak dan mineral alterasi penyusun batuan serisit. Batuan ini merupakan bagian dari jalur magmatisme pada zaman Eosen.

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.
