Abstract

This research is motivated by the fact that currently remote sensing technology continues to develop, both in terms of data collection and processing. This is characterized by the existence of data collection techniques using unmanned aerial vehicles for aerial photo mapping. The advantage of using this technology is that it is effective and efficient both in terms of time and human resources for mapping in areas that are not too large. Another advantage is that it can produce clearer photos, because the plane's flying height is below 400 meters above ground level so that during the shooting process there is no cloud interference. The aim of this research is to create an aerial photo map at the Samarinda State Agricultural Polytechnic, validate objects in aerial photos and in the field, and provide information about the area, boundaries and topography of the Samarinda State Agricultural Polytechnic campus area. The implementation of activities and research objects is the Samarinda State Agricultural Polytechnic campus area. This research uses a small format aerial photo mapping method using a Quadcopter, making it easier to determine where to start taking off and landing. With a Quadcopter vehicle, grounding problems are no longer an obstacle. The research results showed that photography carried out with a Quadcopter at a height of 200 m above the ground produced an area of 28.17 Ha and a spatial resolution of 8.40 cm/pixel. The validation results in aerial photos and in the field using drones have a small difference between 0-4 cm with an average of 1.625 cm/photo. From the digitization results of campus objects, there are 30 objects on campus with a total area of 2.67 Ha. As for the topography results in the campus area, the highest point is 107.5 meters above sea level and the lowest point is 60 meters above sea level.

Abstract

Berau merupakan salah satu kabupaten di Provinsi Kalimantan Timur yang beribukota di Tanjung Redeb. Potensi hutan mangrove di Kabupaten Berau cukup luas mencapai 86 ribu hektar yang harus terus dijaga karena memiliki manfaat dan fungsi yang sangat besar. Vegetasi mangrove di Kabupaten Berau memiliki peran ekologis yang penting, termasuk sebagai habitat bagi berbagai jenis flora dan fauna, serta sebagai pelindung pantai dari erosi. Perubahan kerapatan vegetasi mangrove dapat mencerminkan kondisi kesehatan ekosistem tersebut. Penurunan kerapatan vegetasi dapat menunjukkan adanya degradasi lingkungan yang perlu ditangani. Penelitian ini bertujuan untuk melakukan pemetaan perubahan kerapatan vegetasi mangrove di Kabupaten Berau memanfaatkan teknologi penginderaan jauh, yakni metode Normalized Difference Vegetation Indeks (NDVI) melalui pengolahan data citra Sentinel-2 tahun 2019 sampai tahun 2023. Penggunaan citra satelit, khususnya Sentinel-2A, merupakan pendekatan modern dalam memantau dan menganalisis perubahan vegetasi. Hasil penelitian menunjukkan adanya perubahan kerapatan vegetasi mangrove di Kabupaten Berau dari tahun 2019 hingga 2023. Tahun 2019 kerapatan dengan klasifikasi lebat mencakup 79%. Kawasan mangrove. Menurun drastis menjadi 48% pada tahun 2023. Kerapatan dengan klasifikasi sedang sebesar 4% pada tahun 2019, meningkat menjadi 26% pada tahun 2023. Sedangkan kerapatan dengan klasifikasi jarang sebesar 7% pada tahun 2019 lalu meningkat menjadi 19% pada tahun 2023. Pada penelitian ini berhasil menunjukkan perubahan kerapatan vegetasi mangrove di Kabupaten Berau selama periode 2019-2023 dengan menggunakan metode NDVI. Hasil ini memberikan wawasan yang penting bagi upaya konservasi dan pengelolaan lingkungan di daerah tersebut, serta menunjukkan potensi penggunaan teknologi penginderaan jauh dalam memonitor kondisi vegetasi secara efisien dan akurat.

Abstract

The flow velocity patterns in drainage channels are crucial to study and understand in the context of water and environmental management. Drainage channels play a vital role in conveying rainwater and wastewater, often becoming a limited resource. A deep understanding of the flow velocity patterns in drainage channels is essential to manage water availability, reduce flood risks, and ensure good water quality. These flow velocity patterns are significantly influenced by the geometry, channel topography, water discharge, and other hydrological conditions. Advances in hydraulic modeling technology, such as the use of HEC-RAS software, have enabled more accurate and detailed hydraulic flow simulations. This hydraulic modeling technology is applied to address hydrological issues in the drainage channel on H. Hassan Alwie - Niaga Barat Street, Samarinda City, which frequently experiences water overflow, disrupting mobility and user safety. This study aims to determine the spring tide conditions on the flow velocity distribution in the drainage channel on H. Hassan Alwie - Niaga Barat Street, Samarinda City. Tidal data obtained from the Mahakam River during the spring tide period were used as input in modeling using HEC-RAS 6.5 software. The research results show significant variations in water level and flow velocity in the drainage channel during the spring tide period. The water level reached a maximum of 1.89 meters and a minimum of 0.01 meters, while the flow velocity varied between 0.03 m/s and 0.48 m/s. Mapping the flow velocity distribution revealed clear patterns, with areas of low flow velocity tending to accumulate sediment, potentially causing flooding. These findings provide a better understanding of the interaction between the spring tide phenomenon and urban drainage systems, which can be used to improve drainage planning and management in affected areas.

Abstract

The relocation of Indonesia's capital from Jakarta to Nusantara in East Kalimantan Province has significantly affected land use, particularly in forests and agricultural resources. This study examines the spatiotemporal dynamics of land cover in the forestry and agricultural sectors within Kutai Kartanegara Regency of East Kalimantan Province. The goal is to support the smart forest city concept and enhance food sources within Ibu Kota Nusantara (IKN). Data related to geographical (location) and temporal (time) were analyzed using Geographic Information System (GIS) tools, enabling the mapping, overlaying, and analyzing spatial data over time. The findings show that Kutai Kartanegara has 30% forested areas and 7% agricultural land. There are eight districts with dryland forests, seven with mangrove forests, and fourteen with swamp forests. The study identifies fourteen districts nominated for dryland agriculture, nine for rice fields, and seven for aquaculture. However, forest cover in both drylands and wetlands has been declining annually. Additionally, the study pinpointed potential areas for urban forest development in Tabang District and locations for food production in Anggana, Samboja, and Muara Badak. The findings provide actionable insights for policymakers to optimize land allocation, ensuring sustainable resource management in the evolving ecosystems of the new capital. Keywords: IKN, land cover, food source, forestry, spatiotemporal
