Abstract

Kecamatan Belinyu merupakan kecamatan penghasil timah terbesar di Kabupaten Bangka. Hal ini kemudian menjadikan pertambangan di Kecamatan Belinyu tumbuh tanpa terkendali dan pengawasan terhadap lingkungan tidak terlihat sehingga dampak lingkungan dari penambangan timah mengakibatkan perubahan alih fungsi lahan hutan yang sangat berdampak terhadap munculnya lahan kritis. Bahkan menurut BPS Bangka Belitung tahun 2016 kerusakan hutan secara keseluruhan di Bangka Belitung yang diakibatkan dari aktivitas penambangan timah sebesar 90 ribu hektar. Penelitian ini bertujuan untuk menganalisis perubahan kerapatan kanopi hutan di Kecamatan Belinyu berdasarkan metode penginderaan jauh yaitu forest canopy density pada citra Sentinel-2A dengan analisis multiwaktu pada tahun 2016 dan 2022. Tujuan penelitian berikutnya adalah menganalisis hasil akurasi kerapatan kanopi hutan dari data citra sentinel 2A menggunakan Forest Canopy Density. Perubahan kanopi hutan selama tahun 2016 dan 2022 menunjukan perubahan kerapatan kanopi hutan yang paling luas pada kelas kerapatan rendah 1-10% menurun dari 14768.1 Ha menjadi 1561.54 Ha yaitu, sebesar 13206.56 Ha. Sedangkan berdasarkan pengolahan FCD untuk hasil analisis kerapatan kanopi hutan di Kecamatan Belinyu menggunakan Sentinel-2A tahun 2022 memiliki akurasi 86%.

Abstract

This research aims to: analyze built-up area, rainfall potential, and the effort of groundwater conservation in the Ci Hideung watershed. An experimental method was done to discover the depth of groundwater. Landsat 8 Images are used to analyze the land cover. Rainfall volume is measured by formula; V = Rainfall.area, while the infiltration wells using formula: V = volume (m3).area. The infiltration measurement uses a double ring infiltrometer. Built-up land area are 1.563 km2 (14.77 %) and non built-up area are 9.022km2(85.27 %). The lowest rainfall potential to be absorbed is in May with a volume of 0.282 m3, while the highest is in November with a thickness of 2.912 m. Rainfall volume needs to be absorbed through the infiltration wells on the smallest land unit every 100 m2. The highest rainfall thickness is 2.912, then the volume of 302.40 mm3 was added to the infiltration wells with a length of 1 meter and a wide of 1 meter with a depth of 2.912 meters. Groundwater conservation is highly needed to increase groundwater supply. The highest rainfall volume of 302.40 mm3 could be absorbed in 2.91 hours (174.46 minutes) and the longest is in 3.64 hours. The infiltration wells have a role in storing rainfall to increase groundwater supply so that groundwater surface is also increased.

Abstract

Ci Tarum River is one of the rivers that is widely used for people's lives. Over time, the environmental conditions of the Ci Tarum River have decreased in quality. Ci Tarum has at least five segments with its own characteristics and focus on problems in each segment. Problems commonly encountered along the Ci Tarum stream are caused by land use along the riverbank, characteristics of residents around the river, characteristics and morphology of land around the river, land ownership status and policies and law enforcement. The handling of problems that occur in the river corridor has been implemented in one of the rivers in Melbourne, Australia, namely the Yarra River. There are several things that need to be considered in handling problems in the Ci Tarum River, namely the actual condition and use of land in the river corridor, land tenure status and social control, potential pollutants in the form of liquid and solid waste, community aspirations in the study village as well as pre-design development and utilization development. land in the Ci Tarum River Corridor. The urgency to organize the Ci Tarum River corridors from a physical and social perspective is important to balance or make as proportional as possible.

Abstract

Air quality is a crucial parameter in human life. One air quality indicator can be observed through Aerosol Optical Depth (AOD). If these substances are pollutants such as particulate matter, aerosols, and ozone, it is confident that air quality will deteriorate, threatening human health and causing climate change. AOD monitoring can be used as a basis for policymakers and related parties to maintain the stability of air quality in the atmosphere. Many ground observation stations monitor air quality by obtaining data on PM2.5 and PM10 aerosol particles. However, the number of ground stations is limited, resulting in incomplete data. Fortunately, remote sensing satellites have the advantage of covering large areas and providing continuous observations, with the ability to gather information on large-scale aerosol and obtain spatiotemporal distribution. Therefore, this research aims to obtain AOD through Himawari-8 and analyze the spatiotemporal air quality in urban areas of West Java based on AOD. The research methodology used in this study is descriptive analysis with an empirical research approach. Assisted by remote sensing technology and Geographic Information Systems, this research generates AOD data extraction that can be obtained from the new generation satellite of Himawari-8. The distribution of AOD levels and spatiotemporal monitoring in urban areas of West Java is very dynamic depending on anthropogenic activity in a particular area and time. Keywords: Aerosol Optical Depth (AOD), Air Quality, Himawari-8

Abstract

Floods are one of the many disasters that often occur in Indonesia. Based on data released by BNPB (2017), approximately 31.3% of natural disasters that occur in Indonesia are floods. In general, floods also frequently occur in the administrative area of the Indramayu Regency. Indramayu, which is a coastal area and has topography with an average slope of 0-2%, certainly increases the potential for flood disasters. To help deal with the problem of frequent flooding, radar system remote sensing technology can be utilized to map flood inundation areas effectively. This research was conducted to help identify and map the location of flood inundation in Indramayu Regency using Sentinel-1 multi-temporal Synthetic Aperture Radar (SAR) imagery. Radar images are processed on the Google Earth Engine using the Backscatter algorithm method. The processing results show that an area of 87581.5 ha or 42.1% of the total area of Indramayu Regency has the potential and frequent occurrence of flooding.
