Abstract

Mapping is an activity carried out by geologists to describe the types of rock that make up it, the structure and history of the formation of an area. The research method used is a combination of qualitative and quantitative methods consisting of literature study, field data collection, data analysis and processing, and research reporting. Geomorphological results of the research area consist of hill units in fault zones, intrusive hill units, and denudational hill units with little erosion. The stratigraphy is composed of the youngest to oldest units: andesite lava units, basalt lava units, and diorite units. The structure consists of a primary structure, namely tarpaulin joints and secondary structures, namely tensile joints and shear joints, which result in the main stress direction being northwest-southeast, and shearing to the left. Geological history began in the Middle Miocene from the formation of diorite intrusive rock (Tmb) which then produced Bilungala Volcanic rock (Tpmb (l)) which was composed sequentially from basalt lava which then became andesite lava. During the Pliocene period, a tectonic phase trending northwest-southeast occurred and produced types of thrust faults and left-slip faults (sinistral). The research area is an active volcanic area with intrusive and extrusive rocks which are thought to have the same source. The influence of tectonic subduction in the Sulawesi Sea is an activity that damages the research area apart from human activity.

Abstract

The Talumelito waste storage area is located in Talumelito Village, Telaga Biru District, Gorontalo Regency which accommodates waste from various human activities. Organic and inorganic waste will become a breeding ground for diseases that are very dangerous for society and the environment. The purpose of this study was to determine the subsurface layer as an interpretation of the planning for the construction of a waste storage area and determine whether it is feasible or not. The resistivity geoelectric method of the Schlumberger configuration is one of the geophysical methods that is easy, inexpensive and efficient and does not damage the environment. The geoelectric method is a geophysical method used to identify the properties and physical conditions of the subsurface based on the resistivity values of the rock. This method utilizes variations in the resistivity values of the subsurface rocks to detect geological structures or subsurface rock formations. Based on an analysis of resistivity and geological electrical properties, the location of the planning for the construction of a waste storage area is at VES 2, VES 3, and VES 5 points. Where from the interpretation results the three VES points have bedrock rock layers with granite rock types. Meanwhile, at VES 1 and VES 4, there is a layer of sandstone under the top soil layer. VES 2, VES 3 and VES 5 points are suitable for waste storage because there are layers of waterproof rock. Whereas at VES 1 and VES 4 points it is not suitable for waste storage because the sandstone layer is a layer that has good permeability, so if there is liquid waste from garbage, the waste will contaminate groundwater.

Abstract

Gorontalo has two types of limestone, namely reef limestone and clastic limestone. The research area has several formation units, such as Tinombo, Bilungala, Bone Diorite, Pinogu Volcano, and reef limestone. This research produces an analysis of the limestone depositional environment based on microfacies characteristics, as well as identifying the age of the limestone in the area. This research focuses on the Oluhuta and Olele areas in Bone Bolango Regency. Limestone, as the main focus, is a sedimentary rock with calcium carbonate as the main element. The constituent components involve granules, matrix and cement. Microfacies, the study of rock properties through thin sections, helps identify biological and mineral composition and interpret limestone qualities. The depositional environment of carbonate rocks is determined based on component abundance, grain shape, matrix origin, cement type, and rock packing. The methods used are petrography and micropaleontology. The results of research in the Olohuta - Olele area show that the geological conditions include geomorphological units of alluvial plains, coral reef plains and pyroclastic flow hills. The study area consists of Rudstone facies. Based on petrographic analysis, the research area is included in SMF-5, formed in the FZ-4 environment. Based on micropalentological analysis, the Rudstone Facies is aged N12 – N15 (middle Miocene – late Miocene).

Abstract

Geographically, the observation area is included in Ulunggolaka Village, Latambaga District, Kolaka Regency, Southeast Sulawesi Province. This observation was conducted to determine the paragenesis of the formation of minerals in metamorphic rocks (Schist). The observation method is laboratory analysis (petrographic and mineragraphic analysis). The results of laboratory analysis observations on polished incisions are that there are intergrowth and replacement textures observed between pyrites, sphalerite and chalcopyrite minerals. Paragenesis in the observed samples is that in stage one pyrites are formed and in stage two pyrites and chalcopyrite grow together (intergrowth) and in stage three chalcopyrite is present replacing pyrites and in the last stage sphalerite mineralization is present replacing pyrites. Ore minerals that develop in the observation area are dominated by pyrite and chalcopyrite minerals according to the mineral deposit model included in the low sulfide epithermal deposit type.

Abstract

In simple terms, geodiversity is defined as the diversity of non-living natural components in the form of lithology, minerals, fossils, structures and landforms in an area that forms the earth's surface which has differences, thus forming diversity. Geodiversity can be an important factor in developing the tourism industry and local community identity by conducting special research in the form of investigating geological heritage and cultural heritage and integrating the results for educational outcomes in education, promotion and tourism infrastructure. Gorontalo Province has many locations that show great geological diversity, but many of them have not been explored, studied, or not yet established for geotourism. The extraordinary geo-diversity together with the deep ecological resources and cultural heritage provides a valuable basis for the development of geotourism and geoparks. Geological research at Dulanga Beach has never been carried out to assess the existing geological features. Research on Dulanga Beach generally only focuses on the tourism promotion sector. The aim of this research is to determine the potential geodiversity potential of Dulanga Beach. The method used in this research is the main method, namely geological observation and geodiversity assessment methods. Based on research results, the Dulanga beach location has 3 geological features in the form of geomorphology, lithology and fossils or paleontology. The results of the geodiversity assessment show that the Dulanga Beach research for the Scientific Assessment aspect is in the Moderate class, the Educational Assessment is in the High class, the Tourism Assessment is in the Moderate class, and the Assessment Degradation (Degradation Value) is included in the High class.

Abstract

Digital literacy is becoming an increasingly essential skill for educators in facing the challenges of the 21st century. This study aims to evaluate the effectiveness of digital literacy training for teachers at SDN 9 Kabila and identify the main challenges in adopting technology in education. The research employs an experimental approach through community service activities, involving stages of socialization, training, and evaluation of digital learning media implementation. A total of nine teachers actively participated in each session. The findings indicate that experiential-based training methods result in a more significant improvement in digital literacy skills compared to theoretical training alone. Teachers who engaged in interactive training, such as live demonstrations and digital learning media simulations, demonstrated better competency development than those who only received theoretical materials. This study reveals that while theoretical training provides a strong conceptual foundation, direct application in the classroom is more effective in fostering sustainable digital literacy skills.

Abstract

Indonesia merupakan salah satu negara yang memiliki cadangan bijih nikel laterit terbesar di dunia. Saat ini bijih nikel laterit berkadar rendah tersebut belum diolah secara maksimal menjadi produk yang bernilai tambah di dalam negeri. Proses ekstraksi yang banyak diterapkan di industri untuk bijih nikel laterit berkadar rendah adalah melalui jalur hidrometalurgi. Produk akhir dari proses hidrometalurgi dapat berupa logam Ni dan Co murni maupun produk antara (intermediate product). Salah satu produk antara yang banyak diproduksi adalah presipitat campuran nikel-kobalt hidroksida atau dikenal sebagai MHP (Mixed Hydroxide Precipitate). Presipitasi nikel hidroksida dari larutan hasil pelindian dilakukan pertama-tama dengan mengekstraksi nikel melalui proses pelindian dalam larutan asam sulfat. Selanjutnya pemisahan besi. Larutan yang sudah dipresipitasi besi-nya, selanjutnya digunakan dalam percobaan presipitasi nikel hidroksida. Presipitasi MHP dilakukan dengan menambahkan MgO atau NH3 sebagai agen penetralisasi. Untuk menghasilkan MHP yang berkualitas tinggi proses pemisahan besi dari larutan hasil pelindian dan presipitasi nikel dan kobalt dari larutan yang telah dipisahkan besinya harus dilakukan pada kondisi tertentu. Beberapa parameter yang harus dipenuhi untuk menghasilkan produk MHP yang berkualitas tinggi yaitu kemurnian larutan umpan, pH, suhu, waktu presipitasi danpenambahan seed.

Abstract

This community service activity aims to introduce a spatial approach in disaster mitigation education and environmental conservation based on local wisdom to elementary school students in the coastal area of Tomini Bay. The activity was carried out at SDN 3 Kabila Bone and involved 25 students from grades 1 to 6, selected based on school recommendations and willingness to participate. The method used was classic lectures with the aid of visual media, such as maps of the Tomini Bay area and presentations accompanied by strengthened narratives of local wisdom. The activities took place in an enjoyable learning atmosphere, accompanied by question-and-answer sessions and interactive discussions. The success of the activity was evaluated through direct observation of three cognitive aspects of the students: their ability to recall, understand, and apply the material. The results showed that most students were able to achieve a high level of understanding in all aspects, particularly in applying the knowledge to real-life contexts. The spatial approach made it easier for students to recognize their home region and visually understand potential risks, while local values strengthened students’ connection to their social and cultural environment. This approach is simple, adaptive, and can be implemented in elementary schools in coastal areas with limited access to technology. These findings support the effectiveness of the spatial-cultural approach as a relevant, grounded, and widely replicable model for disaster mitigation education and environmental conservation in other regions with similar characteristics.

Abstract

One of the natural resources commonly utilized as raw material in industries—particularly for piling foundations, construction base mixtures, and other basic building materials—is igneous rock. The quality of the rock used as a construction material plays a crucial role in determining its suitability for various infrastructure applications. Therefore, specific physical and mechanical properties of the rock must be evaluated to assess its feasibility for construction use (Yuwanto and Araujo, 2020). This study aims to analyze the characteristics and quality of the rock at the research site and assess its suitability based on the classification from the Indonesian Industrial Standard (SII) 0378-80. The methods used include the Geological Strength Index (GSI) and Unconfined Compressive Strength (UCS). Data were obtained from field observations using the scan line method and laboratory testing of rock mechanical properties. The GSI analysis shows that the rocks have Structure Condition Rating (SCR) values of 6, 10, and 7, indicating structural influence ranging from blocky/disturbed to disintegrated conditions. The UCS analysis results show compressive strength values ranging from 233.351 kg/cm² to 1.161 kg/cm². According to the SII 0378-80 classification, these values reflect the varying levels of suitability of the rock for construction purposes.
