Abstract

Krakatoa is the most active volcanic complex located in Lampung Province, Indonesia. Throughout human history, several devastating Krakatoa eruptions have shocked the world and turned it into a global attraction. Recognizing its scientific value, Krakatoa has been designated as a geoheritage site. This study refers to the Standard Scientific Value Assessment published by Center for Geological survey of Indonesia, which applies seven main parameters, including well-published scientific reviews, to assess the feasibility of geoheritage sites. In conclusion, the Krakatoa volcanic complex is a highly regarded geoheritage site, scoring 92.5/100. Its significance extends globally, offering insights into the evolution of volcanic islands and their unique geological features. Additionally, the historical records of global catastrophes and the potential for future eruptions warrant further investigation. As a geoheritage site, Krakatoa serves as a reminder of the possibility of subsequent devastating eruptions and its natural history, making it crucial for sustainably maintaining, preserving, and managing its potential for educational, conservation, and scientific purposes. Considering the natural history, the study recommend further consideration of several sustain steps, particularly for sites around the Krakatoa area. Regular and systematic scientific observations and records of natural conditions are significant for maintaining and enhancing Krakatoa as geoheritage.

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

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

Landslide is one of the natural damages caused by mass movement in a natural landscape. The occurrence of landslides causes damage that provides direct and indirect risk effects. Efforts made to reduce the effects of risk can be done by mitigation planning. Batu City is one of the cities located at the foot of Mount Panderman, located at 700-1100 meters DPL. Research was conducted to determine landslide prone areas based on GIS which can then be carried out a sustainable mitigation process. In this area, research was conducted by utilizing GIS in the form of mapping landslide prone areas. Batu city has a predominantly very steep slope that causes high landslide prone areas. Therefore, GIS method can be utilized in mapping landslide vulnerability in Batu city as a map editor and data processor of spatial area which includes rainfall data, soil type data, slope data, and land cover type data.
