Suatu kontrol utama pembentukan alterasi dan mineralisasi adalah struktur geologi, karena dapat menjadi jalur fluida hidrotermal yang membawa mineral ekonomis. Penelitian ini bertujuan untuk menjelaskan kondisi geologi dan menganalisis kontrol struktur geologi terhadap mineralisasi. Metode yang digunakan adalah observasi lapangan. Observasi lapangan terdiri dari pengamatan geomorfologi, struktur geologi dan litologi. Geomorfologi terdiri pengamatan bentang alam dan stadia sungai. Struktur geologi berupa kekar dan sesar. Litologi meliputi alterasi dan mineralisasi. Hasil observasi lapangan dianalisis geomorfologi, stratigrafi, struktur geologi serta analisis laboratorium seperti petrografi dan mineragrafi. Hasil penelitian mendapatkan satuan geomorfologi punggungan vulkanik Motomboto dan satuan perbukitan erosional Motomboto. Hasil analisis stratigrafi dan analisis petrografi didapatkan satuan latit, satuan riolit porfiri, satuan breksi vulkanik dan satuan endapan aluvial. Hasil dari analisis struktur geologi mendapatkan arah umum kekar NE-SW, NW-SE, N-S, NEE-SWW dan sesar terdiri sesar geser dan sesar normal. Secara megaskopis dan analisis mineragrafi, mineral logam yang teramati adalah pirit, kalkopirit, galena, sfalerit, tenanntit-tetrahedrit, kovelit, arsenopirit, emas dan azurit. Hasil analisis kontrol struktur terhadap mineralisasi, mineralisasi terbatas pada breksi hidrotermal yang merupakan batuan hasil dari zona hancuran zona sesar, kemudian terisi oleh fluida hidrotermal yang membawa mineral ekonomis. Struktur geologi daerah penelitian dapat menjadi jalur masuk fluida hidrotermal.

Desa Oluhuta memiliki kekayaan geo diversity dan bio diversity yang melimpah, namun perlu untuk diptomalisasikan, misalnya dengan cara memproduksi sebuah geo produk. Dari hasil survei tim PHP2D UKM Literasi, di Desa Oluhuta terdapat banyak sekali fosil kerang di sekitaran pantai Oluhuta yang bisa dikreasikan menjadi sebuah geo produk. Tujuan penulisan artikel ini yakni untuk menjelaskan serta menguraikan proses pembuatan geo produk khas desa Oluhuta yang diberi nama ‘Makrame Oluhuta’ serta tahapan yang dilakukan dalam memperkenalkan geo produk tersebut pada masyarakat setempat. Hasil yang diperoleh menunjukkan bahwa Makrame Oluhuta yang diproduksi masyarakat setempat mempunyai nilai jual dan daya tarik yang tinggi, dan mampu meningkatkan perekonomian masyarakat setempat dari hasil penjualannya, serta menjadi salah satu instrumen pendukung bagi Desa Oluhuta untuk menjadi desa edu-geowisata.

Geothermal is a type of renewable energy whose utilization can be applied in the tourism sector. This community service aims to increase geothermal knowledge and knowledge about the hazards that can be caused so that students have a basic understanding of geothermal and can minimize the risks or hazards generated by geothermal if students visit geothermal tourism objects. The implementation method is in the form of geothermal learning through the provision of material with interesting handouts and geothermal songs. The results of the community service show that students have basic knowledge of geothermal and have the ability to protect themselves if they are around hot springs.

Gorontalo province is one of the regions in Indonesia that is rich in geological, biological, and cultural diversity, especially Oluhuta Village, Kabila Bone Subdistrict, Bone Bolango Regency. Oluhuta village has 7 main potentials including Oluhuta Human Skeleton Site, Raised Ocean Site, Columnar joint, Petrosia lignosa (Salvador Dali),thousands of coral fish, various coral reefs, and turtles, making it suitable to be developed into a tourism area using the concept of edu-geotourism. The purpose of this article is to outline the stages in the creation of modern infrastructure, namely literacy glamping-based information space in Oluhuta Village as a hallmark of the concept of edu-geotourism developed to optimize tourism potential in Oluhuta Village. The construction of this information space was carried out by the PHP2D SME Literacy team together with the Reformer Youth Movement or Oluhuta Village cadet reef. The result obtained is the creation of an information space that combines the concept of nature and the luxury of presenting information based on the principles of digital literacy and information known as glamping literacy, as a modern infrastructure edu-geotourism, so as to educate tourists and the public to always maintain and preserve the potentials in Oluhuta Village.

Kwandang is a district located in the northern part of Gorontalo. The purpose of this research is to analyze the depth and magnitude earthquake zone that occurred in the district of Kwandang, Gorontalo Utara regency based on seismicity map. The astronomical research location is located at 0° 49' 39" S, 122° 55' 8" E. The method used in this research is seismicity map analysis. The earthquake that dominates in Kwandang, based on the value of its depth, namely shallow earthquake (0-70 km) and medium earthquake (70-300 km). This is caused by subduction activity in the direction of the subduction of the north arm of Sulawesi towards south of Tomini Bay. Whereas based on the strength of the earthquake in Kwandang sub-district is dominated by small earthquakes (-) with a light, mild earthquake. Based on the depth zonation, earthquakes mostly occurred in the west. Based on the magnitude, the earthquakes mostly occurred in the southwest.
