Abstract

Flood is a natural event that is difficult to predict because it comes suddenly with an erratic period, especially in East Balikpapan. There are several important factors that cause flooding in South Balikpapan, including the slope, land cover, and rainfall. The purpose of this study was to determine the flood-prone areas of East Balikpapan based on analysis of the factors that cause flooding, such as rainfall, slope, and land cover and give recommended mitigation.In addition, this study is also to obtain the weight of each factor that affects flooding. The data used in this study include digital data on administrative boundaries, rainfall data, digital data on topographic maps, digital data on land use maps, and field observations. The data is processed using an application based on a Geographic Information System (GIS). The overlay process is carried out using ArcGIS and the weighting is obtained from the Analytical Hierarchy Process (AHP) method. The research area has three categories of areas prone to flooding: not prone, vulnerable, and very prone to flooding. Areas that are not prone are 31.2%, vulnerable 0.001%, and very vulnerable 68.7% of the total research area predominantly located in the south of the study area with the dominance of residential land cover. Recommended mitigation recommendations are the arrangement and construction of good irrigation channels, directly connected to the sea, land clearing paying attention to the marbles of the territory and bozem development

Abstract

Paser Regency is one of the regencies in East Kalimantan which is located in the southernmost part. This district has unique natural conditions and has the potential to become a tourist attraction. Geomorphologically, Paser Regency has various conditions from coastal areas to hilly and mountainous areas. Paser Regency also has geological conditions that vary from Pre-Tertiary to Quaternary age. The purpose of this study is to introduce to the public, both domestically and abroad, geotourism locations in Paser Regency and to examine its geotourism potential. Data was collected using descriptive methods, namely field observations including descriptions, recordings, and measurements to determine the geological and tourist conditions at the research site. Petrological analysis was carried out to determine the type and composition of rocks in detail and was carried out to provide information on the lithological characteristics as edu-geotourism materials at that location. The analysis produces a geotourism map that shows geotourism location information. Paser Regency has 9 locations that have the potential as geotourism objects, namely Lempesu Waterfall, Boga Mountain, Losan Cave, Tengkorak Cave, Loyang Cave, Rambutan Mountain Waterfall, Embung Muru, Doyam Seriam Waterfall, and Danum Layong Hot Spring. Increasing the location of geotourism needs to be done, both in infrastructure development and sustainable management, so that tourists can be comfortable in enjoying their visit.

Abstract

Balikpapan City has recently often experienced flood natural disasters in certain locations, one of which is the Central Balikpapan District which results in losses, this study aims to analyze the flood-prone areas of Central Balikpapan. Analysis of flood-prone areas in this study used a Geographic Information System approach that was aligned with remote sensing. This analysis uses four parameters, namely (1) Slope Slope (2) Land Use (3) Distance to River (4) Rainfall. From the slope analysis of the slope of the study area located in the plain area (at a marble level of 0-13% to 21-55%). The land use analysis of the dominant research area is residential or built-up land.  Analyze the distance to the river with <100-meters closest to the river. Daily rainfall analysis using the Ishoyet method resulted in a rainfall distribution of <13.6 mm which entered the low category. After processing the data of each parameter, a classification of each parameter was obtained in the form of a map, namely a rainfall map with a weight of 0.618448999, a map of the distance to the river with a weight of 0.144534112, a slope map with a weight of 0.122975261 and a land use map with a weight of 0.114041629.

Abstract:  Clay sediment group is one of the dominant sediments in Balikpapan City area which belongs to Balikpapan Formation (tmbp) and Kampung Baru Formation (tpkb) located in the Lower Kutai Basin. The study aims to determine the origin of clay sediments of Balikpapan city by geochemical data. The research methods conducted are the megascopic description, measuring Section, and geochemical analysis. The lithofacies of claystone units in the study area are massive claystone facies (Fm) and lenticular lamination claystone (Clt) which indicate that the sediments originate from Transition - Delta deposition environments. The value of the SiO2/Al2O3 ratio in the clay sediments of Balikpapan City ranges from 0.34 - 0.56 % which indicates that the level of clay composition in the samples is high. The cross plot between the Al2O3/SiO2 and Fe2O3 + MgO percentages indicates that the clay sediments in Balikpapan City are influenced by the oceanic arc zone. This is related to the phase of delta formation process continuing during the Middle Miocene period to the present which is characterized by an increasing volcanic activity.Abstrak: Kelompok sedimen lempung merupakan salah satu sedimen yang dominan di wilayah Kota Balikpapan yang termasuk kedalam Formasi Balikpapan (tmbp) dan Formasi Kampung Baru (tpkb) yang berada di Cekungan Kutai Bawah. Penelitian ini bertujuan untuk mengetahui asal sedimen lempung Kota Balikpapan berdasarkan data geokimia.
