Geologi Daerah Geothermal Pangi Kabupaten Bone Bolango Provinsi Gorontalo
Geology data collection.
Geothermal is associated with volcanic that still has heat energy below the surface. Indonesia is a country with geothermal energy reserves of around 40%. There are 256 potential geothermal areas and only 7 locations have been utilized. Gorontalo has several geothermal manifestations, such as Lombongo, Pangi, Libungo, and Hungayono. The purpose of this study was to study the geology of the geothermal manifestations of Pangi, East Suwawa District, Bone Bolango Regency, Gorontalo Province. The research method is divided into field observations, laboratory analysis, and studio analysis. The results of this research show that the geomorphology in the study area is divided into 3 units, namely the Fluvial Plain, the Volcanic Hills, and the Structural Use Landscape. Alluvial Deposition Unit, Volcanic Breccia Unit, Tuff Lapili Unit, Andesite Unit, Granodiorite Unit, and Porphyry Diorite Unit.
Keywords: Geology, Gorontalo, Manifestasi Geothermal, Pangi.

Geologi Daerah Dimito dan Sekitarnya Kabupaten Boalemo Provinsi Gorontalo
Reconstruction of geologic history of Dimito (Badaru, 2019).
Administratively, the research area covers two districts, Wonosari Sub-district and Dulupi Sub-district, Boalemo District, Gorontalo Province. Based on the physiography of the Gorontalo region, the research area which is included in the southern mountain zone of Bone-Tilamuta-Modello generally consists of ancient volcano-sedimentary rock formations in Gorontalo, the Eocene-Oligocene. The purpose of this geological research is to discover the geological order that developed in the area of Dimito and surrounding are as covering several aspect such as geomorphology, stratigraphy, geological structure, and geological history. The result shows that the geomorphology of the research area divided into three geomorphic units, namely the units of the Alluvial Plain, Volcanic Hills, and Denudasional Hills. Stratigraphy of the research area divided into five types of units sorted from the early Miocene to the Holocene, i.e., Lava Basal Dimito (Early Eocene), Wackestone Dimito (Early Eocene), Andesit Kalidingin (Middle Miocene), Granodiorite Bualo (Middle Pliocene), and Alluvial Buaolo (Recen). Geological structures that work on the location of the research area relatively trend from northeast-southwest to northwest-southeast. Fault working on the location of the research area from the data processing consists of Normal Left Slip Fault Kalidingin and Lag Left Slip Fault Bualo.

Earthquake Damage Level of Gorontalo Area Based on Seismicity and Peak Ground Acceleration
Cross section of earthquake depth of Gorontalo and surrounding area (Manyoe, 2019).
Gorontalo is located at the macro and micro plate boundary, therefore it is located in an active seismotectonic region. This study aims to analyze earthquake damage level in Gorontalo based on seismicity and peak ground acceleration. The data used is obtained from the USGS. Data is made into a database and plotted onto a geological map. Calculation of peak ground acceleration is obtained using the Kawashumi formula. The results of this study indicate that Gorontalo is included in the slight to moderate earthquake damage level because it is dominated by shallow to intermediate earthquakes depth, light to moderate earthquake magnitude, and have a peak ground acceleration 1,462 - 99,714 gal.
Keywords: Seismicity, Peak Ground Acceleration, Earthquake, Gorontalo.

Geologi Ilotidea dan Kampung Sains Wisata Banjir
Buku Geologi Ilotidea dan Kampung Sains Wisata Banjir.
Buku Geologi Ilotidea dan Kampung Sains Wisata Banjir membahas tentang geologi, geomorfologi, geofisika dan fenomena banjir di daerah Ilotidea serta solusi tentang Kampung Sains Wisata Banjir untuk daerah Ilotidea. Adalah hal yang mainstream dalam masyarakat untuk mengungsi dan menunggu bantuan pemerintah saat terjadi banjir. Buku Geologi Ilotidea dan Kampung Sains Wisata Banjir menghadirkan sebuah pemikiran dan solusi yang tidak lagi melihat banjir sebagai bencana tapi sebagai sumber pendapatan masyarakat melalui pengembangan kampung sains wisata banjir.

Belajar Gempa Ceria
Buku Braille Belajar Gempa Ceria.
Gempa adalah hentakan asli dari kulit bumi yang terjadi karena adanya pergerakan lempeng dan sesar aktif. Mitigasi bencana gempa adalah salah satu upaya untuk mengurangi jatuhnya korban jiwa akibat terjadinya gempa. Sampai saat ini gempa belum dapat diprediksi tempat dan waktu kejadiannya. Agar tidak jatuh korban jiwa maka yang dapat dilakukan adalah upaya mitigasi. Buku Belajar Gempa Ceria disusun untuk memberikan pengenalan mengenai gempa dan langkah-langkah mitigasi yang dapat dilakukan saat dan setelah terjadi gempa. Buku Belajar Gempa Ceria merupakan buku braille kegempaan yang ditujukan buat penyandang tuna netra terutama anak-anak agar memiliki kemampuan mitigasi bila terjadi bencana gempa, juga buat para guru dan orangtua agar dapat mengajarkan dan menerapkannya di sekolah dan rumah.
