Abstract

Land cover undergoes changes every year. Such development might be uncontrolled, making it crucial to monitor changes in land cover. Monitoring land cover changes can be conducted using satellite imagery, especially Landsat images. This study was conducted in the Katobu District, Muna Regenvy, and aimed to: (1) identify changes in land cover from 2017-2022 in the Katobu Subdistrict, Muna District; (2) analyze the direction of built land development from 2017-2022; (3) understand the factors influencing the direction of built land development. The data used in this study include the type of land cover from Landsat images, sample coordinate points from field surveys, and data on factors affecting the direction of built land development obtained from interviews. The data analysis methods used are overlay and quantitative descriptive. The research results include: (1) the most significant land cover change from 2017-2022 was the transformation from shrub land to built land, with a change of 27,86 hectares or 2,84%; (2) the direction of built land development in the Katobu Subdistrict from 2017-2022 tends to head towards the Batalaiworu Subdistrict; (3) the influencing factors are non-physical factors such as population growth/total population and city activities.

Abstract

Earthquake is one of the disasters that can cause damage and losses to the affected communities. This research was conducted in the Moramo District hills, where an earthquake incident had occurred previously. The objectives of this study are to determine the characteristics of the region based on the parameters of earthquake damage vulnerability and to determine the spatial distribution of earthquake damage-prone zones based on interpolation results. The sample data consisted of microtremor data using the Quota Sampling method at 15 field measurement points and the shapefile of the Southeast Sulawesi Province. The data was processed using the Geopsy application and mapped using the IDW method by calculating the RMSE value to select the best interpolation result. The findings of this study are: The research area is generally vulnerable to damage caused by earthquakes, although the level of vulnerability tends to be low. There are three zones prone to earthquake damage: a low-damage zone covering almost the entire research area (eastern part of Pudaria Jaya, northern Wonua Jaya, western and southern Sumber Sari, and western Ulusena). A moderate-damage zone is located in the northern part of Watu Poramba, Wonua Jaya, and Sumber Sari, as well as western Ulusena. Meanwhile, a high-damage zone is found at T2, located in Pudaria Jaya Village.

Abstract

Increasing population densities and food demands are major factors contributing to the widespread use of agricultural drylands in upper volcanic slope areas. This phenomenon poses a high risk of severe erosional events that are environmentally hazardous. Therefore, this study aims to analyze the sediment flow characteristics, based on the relationship between sediment flow and water level as well as the sediment discharge rate and soil loss. Field surveys were conducted to determine the soil measurement, slope morphology and dryland cover characteristics. The sediment flow was evaluated at the gully outlet, where 169 suspension data pairs for the modeling and 130 suspension data pairs for the validation, as well as the bed load, water level, rainfall and water flow characteristics were obtained. Tables and figures were subsequently used to represent the measurement data and analysis results for the correlation between the flow rate effects, sediment and soil loss on the water surface. The results showed that the sediment flow in volcanic landscape slopes with dryland agriculture were possibly characterized by the polynomial relationship, using the suspension discharge model, Qs=0.0322Q2+6.0625Q–1.2658. Under this condition, the average rate of soil loss in the form of sediment load and erosion rate of the catchment area occurred at 953.53 and ​​1,657.94 ton/ha/yr, respectively. Furthermore, the sediment sources in the soil loss were believed to originate from 83% of the suspended sediments and 17% bed loads.

Abstract

Suspension flow into the upstream of volcano watershed is sensitive to land use. In Indonesia, a settlement is a form of land use in several volcanic landscapes. There is currently no detailed study on the suspension flow sediment from the settlement land use. The purpose of this study is to investigate the characteristics of the relationship between water and suspension flow discharge. The study was conducted through the measurements at a gully outlet that produced 747 suspension load data. For each rainfall event, suspension load measurements were made in the field, followed by laboratory analysis. Additionally, field surveys were used to determine the characteristics of settlement land use and the water flow into the gully system. According to the findings, the peak flow discharge corresponds to the peak suspension discharge, the peak flow discharge comes before the peak suspension discharge, and the peak flow discharge happens after the peak suspension discharge. The average time lag between initial rainfall events and suspension flow was 10.36 minutes, and the suspension peak content varied by an average of 2.22 gl-1. The grain size was also dominated by the clay fraction, averaging 67.86% on the ascending branch and 67.82% on the descending branch.

Abstract

Sediment flows in volcanic landscapes are sensitive to land uses. Settlements of land use are often found along the slopes of volcanoes in Indonesia. Many detailed studies of sediment discharge in agroforestry and dryland in volcanic slopes have been carried out. Meanwhile, the settlement's land use is not of interest to researchers. This study aims to build a model of sediment discharge in settlement areas of volcanic landscapes with a focus on (1) the relationship between sediment discharge and water flow discharge; and (2) the sediment rate and soil loss in settlement land use. The study used the key area method in watershed areas that have settlements land use. The research was carried out using field surveys to observe soil, slope morphology, and the settlement's land cover characteristics. Sediment flow was measured in the suspended sediment data and bedload sediment. Water flow data was measured in the canal water level and the rain data was measured with an automatic water level recorder and the Automatic Rain Recorder, as well as field observations of the characteristics of the flows entering the canal system. Data analysis was carried out to produce a model of sediment discharge, and the rate of soil loss. The research resulted in a suspension discharge Qs=0.4396Q1.2123 and a soil loss rate of 5.04 tons/year.AbstrakAliran sedimen bentanglahan gunungapi sensitif terhadap bentuk-bentuk penggunaan lahannya.

Abstract

Kendari City is an area prone to earthquakes because it is in a seismic zone dominated by local faults such as the Lawanopo Fault, Kendari Fault, Buton Fault, Tolo Thrust and Matano Fault, as evidenced by significant seismic events like those in 2011 and 2022. The earthquake in 2011, with a magnitude of 6.0, struck Kolono District, South Konawe Regency, while the 2022 earthquake, registering a magnitude of 5.2, occurred in the sea approximately 5 km north of Soropia, Konawe Regency. With seismic activity such as the 2011 and 2022 earthquakes causing significant damage, understanding seismic hazards is critical. The research stage starts from Hazard Analysis using the Classical Probabilistic Seismic Hazard Analysis (PSHA) method to produce a hazard map that presents the distribution of peak ground acceleration on the surface, at periods 0 seconds (PGA), SA (T= 0.2 seconds) and SA (T= 1.0 seconds) for probabilities of exceedance 10% and 2% in 50 years, respectively. Classical Probabilistic Seismic Hazard Analysis (PSHA) processing uses OpenQuake Engine software. The analysis results show that the PGA value in Kendari City on the surface ranged from (0.49 - 0.68 g and 0.79 - 1.17 g), SA at T= 0.2 seconds (1.10 - 1.53 g and 1.74 - 2.09 g), and SA at T= 1 second (0.64 - 0.93 g and 1.35 - 1.91 g). This result indicates the potential for significant damage and shocks.
