Masalah sampah adalah masalah klasik yang sudah lama melanda kotakotabesar di Indonesia. Masalah tersebut muncul karena terbatasnya lahan kosongyang dapat dijadikan sebagai tempat pembuangan akhir sampah, sementara produksisampah tiap hari terus berlangsung. Pemda Bone Bolango juga tak luput daripermasalahan tersebut. Oleh karena itu, mereka mencari lokasi tempat pembuangansampah yang transportasinya mudah di jangkau dari kota Kabila, jauh dari saranaumum dan pemukiman warga. Atas dasar hal tersebut desa Tulaa dipilih sebagairencana lokasi tempat pembuangan sampah. Namun untuk mengetahui daya dukungbatuan bawah permukaan di lokasi yang akan dijadikan tempat pembuangan sampahmaka perlu dilakukan penelitian geofisika dengan metode geolistrik resistivitaskonfigurasi schlumberger. Hasil interpretasi pengukuran geolistrik diperoleh bahwalokasi desa Tulaa kurang baik karena tidak adanya lapisan kedap air yang menutupilapisan air tanah (akuifer), sehingga sangat mungkin ketika ada limbah cair darisampah, limbah tersebut akan terinfiltrasi ke dalam tanah sampai ke lapisan akuiferdan pada akhirnya akan mencemari air tanah.

Kota Tengah Subdistrict has the highest population density in Gorontalo City, with a population density of 6,755 people/km2. This high population density requires a large amount of water to meet the needs of the population, where one form of fulfillment is taken from groundwater. For this reason, it is necessary and important to know the characteristics of aquifers. This study aims to determine the characteristics of groundwater aquifers in the Kota Tengah Subdistrict. The method used is the resistivity geoelectric method to obtain aquifer characteristics in the form of material type (lithology), depth, and thickness of the aquifer. Based on the geoelectrical analysis in TS 01 there are 4 layers, namely topsoil, clay sand, sand, and clay; TS 02 contains topsoil, sand, and clay layers; TS 03 contains topsoil, sand, and clay. The study found that the lithology of the near-surface layer in the Kota Tengah subdistrict can be classified into aquifers and aquicludes. The aquifer layer is formed by sand-sized sedimentary deposits that have high permeability while the aquiclude is clay-sized which is impermeable. The aquifer layer was found starting from a depth of 0.57 m. The average thickness of the aquifer layer was 13.8 m which is interpreted as an unconfined aquifer. This study also found other deeper aquifer layers as confined aquifers that can not be further interpreted due to the limitations of the method used.

Tihu Village is located on the southern coast of Gorontalo and is included in an area prone to earthquakes and tsunamis. The impact of the earthquake and tsunami disaster can be in the form of loss of life and material. The losses incurred as a result of a disaster are usually caused by the local community's lack of responsiveness in dealing with an impending disaster. Mitigation efforts are needed in tsunami-prone areas to prevent casualties and material losses. Mitigation efforts can be carried out by socializing the earthquake and tsunami disaster and making tsunami evacuation routes. The programs implemented through this service activity are: 1) survey of potential disasters and identification of disaster-prone zones; 2) manufacture of disaster risk reduction information boards; 3) construction of evacuation route boards and assembly points; 4) Socialization of earthquake and tsunami disaster risk reduction; 5) Installation of evacuation route boards and assembly points.

Regionally, the research area is composed of volcanic and plutonic rocks. Stratigraphic data of the study area are still regional scale. This study aims to analyze detailed stratigraphic data and formulate the geological history of the Limbato area and its surroundings. The area located at coordinates 0Âº56â€™6â€ - 1Âº0â€™10.8â€ N dan 122Âº5â€™56.4â€ - 122Âº9â€™10.8â€ E, the area of the study is around 45 kmÂ². The method used in the research is scientific exploration by conducting a surface geological mapping survey. The geological surface in the form of field data collection and laboratory analysis. Field data in the form of lithology data and laboratory analysis in the form of petrology and petrographic analysis. The stratigraphy of the research area is divided into 4 (four) unofficial units, which are sorted from old to young, namely granodiorite units of Middle Miocene age, volcanic breccia units of Late Miocene to Early Pliocene, andesite units of Middle Pliocene and alluvial units of Holocene age.Stratigraphic analysis of the Limbato area is related to geological history. In the Middle Miocene period subduction formed plutonic rocks that produced granodiorite units, then during the Late Miocene volcanic eruptions resulted in volcanic breccia units. The activity was stopped at the time of the Early Pliocene. After the volcanic activity was stopped, then new magma activity occurred at the time of the Middle Pliocene resulting in an andesite unit. After all rock units have been deposited, an erosion process occurs in older units which results in an alluvial unit.
