Abstract

Landslide is one of the natural disasters that often occurs in Indonesia, which has various geographical conditions and different topography of different areas. Landslide is one of the natural disasters that often occurs in Indonesia as a country that has various geographical conditions and different topography of different areas. However, an exhaustive study of spatial use which includes suitability assessment between the Regional Spatial Plan (Rencana Tata Ruang Wilayah/RTRW) documents and regional potential and other factors such as disasters is still rarely carried out. Tanjungsari District, Bogor Regency is an area that has experienced landslides in January 2020. The purpose of this study was to evaluate the RTRW of Bogor Regency against landslides in Tanjungsari District. The vulnerability of a site to landslides is caused by several factors which are used as parameters in this study. The parameters are land use, rainfall, slope, geology, and soil type. Each parameter used is given a score and weight then an overlay of each parameter weighting is carried out to obtain a landslide susceptibility map. Furthermore, a descriptive spatial analysis of the landslide hazard was carried out on the spatial plan of the Bogor Regency. The results when compared with the existing conditions, the use of plantation land and forest areas overlap with areas prone to landslides. Thus, it is necessary to review the existing RTRW maps to reduce the impact of landslides.

Abstract

Land cover change is a prevalent thing in Indonesia. This phenomenon often causes deforestation rates to continue to increase every year, which can cause various natural disasters. This study will look at changes in land cover, make land cover prediction models, and see the relationship between land cover changes and the flood disaster that occurred in Banjarmasin City and its surroundings. Remote sensing is used to see changes in land cover from year to year with GlobeLand30 satellite imagery. Satellite imagery processing is carried out using the Cellular Automata – Markov Chain method to see the land cover prediction. The results show that the most significant land cover change from 2000 to 2020 is experienced by built-up land and forests, while in 2030, forests are predicted to experience deforestation of 356 km2 from 2020. The deforestation will cause catastrophic flooding in 2021, where flooding extends to areas that are not estimated to be high flood hazards, with 111 flood points located in the plantation area.

Abstract

Berdasarkan data kejadian longsor, Kecamatan Sirimau merupakan daerah yang rawan longsor di Kota Ambon. Salah satu langkah awal dalam mitigasi bencana longsor di Kecamatan Sirimau adalah dengan memetakan daerah-daerah yang berpotensi longsor. Tujuan dari penelitian ini adalah untuk mengetahui sebaran spasial kawasan rawan longsor di Kecamatan Sirimau. Metode SMORPH digunakan untuk identifikasi dan klasifikasi daerah yang berpotensi longsor berdasarkan matriks bentuk lereng dan sudut kemiringan lereng. Kajian ini menghasilkan 4 tingkatan daerah yang berpotensi longsor, yaitu potensi sangat rendah, rendah, sedang, dan tinggi. Desa dengan potensi longsor tinggi adalah desa Soya dan desa dengan potensi longsor sangat rendah adalah desa Galala. Hasil penelitian ini juga menggambarkan bahwa semakin tinggi kemiringan lereng dan bentuk lereng yang cembung atau cekung maka potensi terjadinya longsor semakin tinggi. Hasil penelitian diharapkan dapat membantu pemerintah Kecamatan Sirimau dalam upaya membuat penataan ruang berbasis mitigasi bencana.

Abstract

A healthy coral reef ecosystem can be beneficial for the survival of fish habitats and aquatic ecosystems. This study aims to analyze the influence of human activities on the spatial distribution of coral reefs in the coastal waters of Samatellu Lompo Island, Pangkajene Islands Regency, South Sulawesi in 2000, 2014, 2018, and 2021. The spatial distribution of coral reefs was obtained through a field survey using the underwater transect photo method. Then, satellite images were processed by using the Lyzenga algorithm for water column correction, and aquatic objects were classified by using unsupervised classification. Human activities that affect coral reef destruction were obtained through interviews and it was strengthened with related literature studies. The results showed that the coral reefs in the coastal waters of Samatellu Lompo decreased from 2000-2021. In 2000, the live coral area was 13.53 ha, whereas in 2021 it was 8,031 ha. Destructive fishing activities such as using bombs and poison in catching fish are the main factors of coral reef destruction. In addition, destructive fishing activities commonly occur in the western and northern waters of Samatellu Lompo that causing the live coral into dead coral or rubble.

Abstract

AbstractOne of the impacts of climate change is the degradation quality of natural habitats of flora and fauna in Indonesia, risking the loss of most of the existing biodiversity. Obi Island as a natural habitat for several endemic species cannot be avoided from the threat of climate change impacts. The existence of mining concessions also can have a direct impact on their habitat potential. The purpose of this study was to analyze the distribution pattern of endemic species under current climatic conditions, synthesize models of the impact of climate change and analyze mining concessions on the distribution of potential habitats of Carunculated Fruit-dove on Obi Island. The occurrence data of Carunculated Fruit-dove and 19 bioclimatic variables are used as input in the process of making a habitat model with MaxEnt. As a result, the habitat potential model of Carunculated Fruit-dove with AUC = 0.955 has a very suitable habitat potential with an area of 66.02 km2 or 2.68%. The climate change in 2041-2060 with 4 different climate scenarios has an impact on the Carunculated Fruit-dove habitat potential model. Mining Business Permit Areas on Obi Island that have been issued until March 2022 amount to 19 locations with a total area of 373.14 km2 which will have a direct or indirect impact on the potential habitat of Carunculated Fruit-dove on Obi Island. 14.17 km2 of 66.67 km2 of potential habitat that is very suitable for Carunculated Fruit-dove will be directly affected by the existence of these mining areas.Keywords: endemic species, mining business permit area, climate change, obi island, maximum entropy

Abstract

Palabuhanratu Village is one of the villages in Sukabumi, West Java, that is susceptible to earthquake and tsunami risks. This research intends to revise the tsunami hazard map, undertake a spatial analysis of the distribution of evacuation sites, and identify optimal tsunami evacuation routes. The tsunami hazard map was updated using tsunami modeling with COMCOT based on the worst-case scenario of potential magnitude moment 8.8 for the Megathrust segment in the south of West Java from PuSGeN. This modeling was used to predict the worst probable tsunami impact. On the basis of field survey data regarding the location of evacuation sites, evaluation of the distribution of evacuation sites was conducted. In addition, service area analysis is utilized to assess the service area of the present evacuation site in relation to each hamlet in Palabuhanratu village. Approximately 57.33 percent of the town could be affected by a tsunami, according to the findings of this study. The greatest tsunami height along the coast is expected to be between 18 and 22 meters, and the arrival time is 22 minutes. From a total of 35 hamlets, we determined that two hamlets in the Palabuhanratu village area were not harmed by the tsunami. Because not everyone can reach the evacuation location in time, the findings of this study show the need for an additional vertical evacuation site.

Abstract

Tea leaves are the most important part for consumption. Leaves that are healthy have a distinct color, while leaves that are not healthy have a color that is very different from the original. Chlorophyll in leaves effects the reflection of infrared light, allowing healthy plants to reflect more infrared light than unhealthy plants. Leaf color and chlorophyll have an important role in showing the growth and health of tea plants. Remote sensing consists of collecting information about objects and features without contacting the equipment. The Normalized Difference Vegetation Index (NDVI), one of the first remote sensing analysis products used to simplify the complexity of multispectral imaging, is now the most commonly used index for botanical assessment. inconsistencies in NDVI depending on sensor-specific spatial and spectral resolutions. Different parts of the leaf have discolored spots due to health conditions or nutritional stress, so there are different spectral values on different parts of the leaf. Unhealthy tea leaves have low NIR values due to disease, insects, and sunburn, which damage the chloroplast structure of the leaves, weaken the absorption of the appropriate band, and increase reflectance. There is a difference between the measurement results of the NDVI spectrometer and the sentinel image. This is due to the fact that the Sentinel-2 image can only retrieve image pixels with a resolution and not diseased leaf parts, as with the use of a spectrometer, which directly extracts the value of the infected area from the normal part of the plant

Abstract

Indonesia's tea production and export volume have fluctuated with a downward trend in the last five years, partly due to the increasingly competitive world tea quality. Crop yield estimation is part of the management of tea plucking, affecting tea quality and quantity. The constraint in estimating crop yields requires technology that can make the process more effective and efficient. Remote sensing technology and machine learning have been widely used in precision agriculture. Recently, big data processing, especially remote sensing data, machine learning, and deep learning have been carried out using a cloud computing platform. Therefore, we propose using GeoAI, a combination of Sentinel-2A imagery, machine learning, and Google Collaboratory, to predict ready for plucking tea leaves at optimal plucking time at Gunung Mas Plantation Bogor. We used selected bands of Sentinel-2A and extracted more features (i.e., NDVI) as a training set. Then we utilized the tea blocks boundary and tea plucking data to generate labels using Random Forest (RF) and Support Vector Machine (SVM). The classification results were further used to estimate the production of crop tea yield. The RF classifier is able to achieve overall accuracy at 51% and SVM at 54%. Meanwhile, accuracy at optimally aged tea blocks is able to achieve at 75.62% for RF and 52.88% for SVM. Thus, the SVM classifier is better in terms of overall accuracy. Meanwhile, the RF classifier is superior in predicting ready for plucking tea at optimally aged tea blocks.

Abstract

The increasing area of land burned in 2021 makes the government urgent to map areas prone to forest fires in Situbondo Regency. This study analyzes areas prone to forest and land fires using the SMCA method. The research analysis used variables of land cover type, the greenness of vegetation, vegetation humidity, land surface temperature, and human factors. The human elements in question are accessibility (distance from the road network) and distance from human activities (distance from settlements, fields, and plantations). The conclusion analysis of forest fire-prone areas is divided into three classes that are high, medium, and low. From the vulnerability model that has emerged, it was found that most of Situbondo Regency have a high grade of forest fire vulnerability with an area of 652.66 km² (39.08%). The areas with the level of vulnerability of the middle, low, and non-vulnerable classes, respectively, are 532.12 km² (31.87%), 306.46 km² (18.35%), and 178.65 km² (10, 70%). The results of statistical tests using the ordinal logistic regression method show that natural factors for forest and land fires had a higher level of influence (? = 4.824) on forest and land fire vulnerability compared to human factors (? = 1.051).
