Abstract

Karang Mumus watershed is an important area as a port and gateway to the inland of East Kalimantan, causing the trade sector and water transportation services in this city to be very developed. Traders and immigrants from various regions who came in, stopped by, performed business, and stayed have caused the riverbanks to develop into economic and trade centers. One of the issues in the Karang Mumus sub-watershed is the conversion of forest area to agricultural land. With the improper use of agrotechnology and soil conservation, agricultural operations result in erosion and reduced land yield. This study aims to evaluate the Karang Mumus sub-potential watersheds to support land capability by using the overlay method (geoprocessing) of a geographic information system (GIS) based on criteria for classifying land capabilities and a data analysis approach. The findings revealed that the Karang Mumus sub-land watersheds primarily are categorized as land capacity class III, with a moderate erosion limiting factor that covers 15,864 ha (50.45%). The remaining areas are categorized into land capability classes IV and VI, with class IV having a severe slope limiting factor and class VI having a severe slope limiting factor with a fairly strong soil sensitivity to erosion, covering 8,751.14 ha (27.83%) and 6,829.85 ha (21.72%), respectively. Class III land is recommended for agricultural cultivation, application of appropriate agro-technology, and soil and water conservation. This study recommends that class IV and VI lands area are used for community forests or plantation forests managed by government agencies involved in the forest area stabilization center (BPKH) Region IV Samarinda.

Abstract

Penyebab pemanasan global adalah meningkatnya emisi CO2 di atmosfer. Kondisi ini menyebabkan bumi semakin panas dan mempengaruhi kehidupan di masa yang akan datang, es di daerah kutub mencair, permukaan laut naik setiap tahun, hingga terciptanya badai angin. Kondisi lingkungan seperti ini dapat membahayakan generasi di masa yang akan datang. Pemakaian listrik dari pembangkit berbahan bakar menggunakan fosil, merupakan salah satu penyebab terjadinya pemanasan global, karena dapat meningkatkan emisi CO2. Bangunan yang didesain tidak memperhitungkan pemakaian listrik, merupakan salah satu kontribusi dalam perusak lingkungan. Kebutuhan listrik tidak dapat dihindari karena pesatnya perkembangan teknologi. Pengaruh iklim luar daerah tropis yang panas berpengaruh ke dalam bangunan, menyebabkan beban pendinginan semakin besar. 40-50% energi listrik dalam bangunan dibutuhkan untuk proses pendinginan ruang (Air Conditioner), presentasi ini akan semakin besar kalau iklim di luar semakin panas. Usaha penghematan listrik pada skala bangunan dengan cara mentraitment konfigurasi arsitekturnya. Penyebab panas pada bangunan 80% berasal dari luar bangunan dengan mempertimbangkan desain sistem penerangan, pendinginan dan kulit bangunan. Dapat mencapai 70% pengurangan penggunaan listrik dengan penstimulasian antara model bangunan yang respond dan tidak terhadap lingkungan. Lebih hemat lagi 30-40% bila desain bangunan melibatkan penggunaan unsur tanaman dan air. Penelitian menegaskan bahwa aspek desain bangunan sangat berpengaruh terhadap penggunaan energi listrik, dan berkontribusi pada kepedulian terhadap pemanasan global dunia.

Abstract

The practical science of Geodesy is making maps of large or small parts of the earth's surface. The City of Samarinda currently has the problem of not having a city map for city government officials or local residents. The absence of a city map makes it difficult for city officials and the public to find out information on sub-district boundaries and land use in the Pelabuhan Subdistrict area, the District of Samarinda Kota. To create a map of the boundaries of the Pelabuhan Subdistrict above, a survey was carried out using a handheld GPS to surround and identify the boundaries of the Pelabuhan Subdistrict according to the direction of one of the District of Samarinda Kota officials who was very knowledgeable about the conditions in the field. The creation of the Pelabuhan Subdistrict boundary map was carried out through a digitization process in the QGIS application by displaying corrected satellite imagery. Through the QGIS application, digitization is carried out according to the conditions and conditions at the location, by paying attention to the appearance of the earth on satellite images of the City of Samarinda. The objects digitized in this process are the boundaries of the Pelabuhan Subdistrict, the District of Samarinda Kota, and public facilities. Apart from that, interpretation was carried out and it was found that land use in the District of Samarinda Kota, the City of Samarinda includes green open space, city utilities and built-up land. Land use in the form of trade and service centers is almost evenly distributed throughout the District of Samarinda Kota.

Abstract

Excessive surface runoff  is often underestimated concerning flood mitigation. Indeed, flooding has become a recurring disaster in the past 20 years in Indonesia. This research aims to determine the erosion hazard level and develop conservation plans for dryland agriculture and oil palm plantations to mitigate surface runoff, thereby reducing the risk of flooding. The data collected includes hydrology, dryland agricultural areas, oil palm plantations, and topography, which are analyzed based on threats and conservation potential.  Conservation plans that can be implemented include  Minor  Recharge Holes (MRH) in dryland agriculture and dead-end ponds Palm Dead Pond  (PDP) in oil palm plantations. The research results indicate that the MRH design, with a diameter of 1-1.5 m and a depth of 1-1.5 m, still results in surface runoff exceeding 70%. Meanwhile, the PDP design, with a depth of 1-1.5 m and a size of 1-1.5 x 1-1.5 x 7-8 m, yields runoff below 50%, even during extreme rainfall (220 mm), with runoff being only 2%. A change in land use, primarily dominated by dryland agriculture and oil palm plantations, has been a significant factor in triggering flooding in the Arui watershed. In addition to MRH and PDP, five rivers can accommodate surface runoff, which is expected to contribute to long-term flood mitigation in the  Arui watershed.

Abstract

Limpasan permukaan tinggi berdampak penurunan air yang masuk kedalam tanah, sehingga menurunkan ketersedian air tanah. Peningkatan limpasan permukaan sering diabaikan dalam upaya mitigasi banjir dan ketersediaan air. Padahal ketersediaan air yang cukup dan berkualitas sangat berhubungan dengan seberapa besar jumlah air yang masuk ke dalam tanah. Penelitian ini bertujuan untuk menentukan kapasitas infiltrasi pada tiga jenis tegakan dengan menggunakan double ring infiltrometer . Pengumpulan data selain infiltrasi diantaranya kadar air tanah, keadaan tiga vegetasi, sifat fisik dan kimia tanah seperti tekstur, struktur tanah, bulk density, porositas tanah, permeabilitas tanah, dan bahan organik tanah. Hasil penelitian menunjukan pada tegakan Aucaria hunsteinii memiliki kapasitas infiltrasi terbesar diikuti berturut turut di bawah tegakan Intsia bijuga dan di bawah tegakan Swietenia macrophylla. Faktor-faktor yang mempengaruhi kapasitas infiltrasi diantaranya keadaan vegetasi, kadar air tanah, permeabilitas tanah, kerapatan massa tanah, porositas tanah, tekstur dan struktur tanah. Porositas tanah, tekstur tanah dan permeabilitas tanah mempunyai pengaruh paling besar untuk terjadi peningkatan infiltrasi dibandingkan faktor-faktor lain

Abstract

The Universitas 17 Agustus 1945 (UNTAG) Samarinda is one of the educational institutions located in urban areas with high development pressure. The existence of green open spaces in the campus environment plays an important role in maintaining ecological balance, thermal comfort, and air quality for the academic community. This study aims to evaluate the level of vegetation density and proportion of green open space utilization in the UNTAG Samarinda campus area using the Geographic Information System (GIS) approach. Spatial data was obtained from high-resolution satellite imagery in 2024 and field interpretation results that included tree vegetation, shrubs, and non-green areas (buildings and roads). Data processing is carried out through the stages of geometric correction, land cover classification, and vegetation index analysis (NDVI). The results of the analysis showed that of the total land area ±2.98 hectares, around 32.6% is a vegetation area with a medium-high density level, while the rest is in the form of buildings, parking areas, and road access. These findings show the need for a more optimal Green Open Space management strategy through increasing vertical vegetation and greening in the open areas of the campus. GIS integration has proven to be effective in providing accurate spatial information to support sustainable campus planning and support UNTAG Samarinda's "Green Campus" vision.

Abstract

This study aims to evaluate the surface carbon stock estimation model in Kendari City working area using Geographic Information Systems (GIS) and remote sensing approaches. Spatial analysis was carried out using Sentinel-2A satellite imagery with a resolution of 10 meters per pixel, employing the vegetation index method as the primary indicator for estimating carbon stocks. Field data were used as reference and validation for image interpretation results, which were processed using spatial statistical methods to produce an accurate and reliable surface carbon distribution model. The research findings indicate that the Kendari City area has a significantly varied distribution of carbon stocks, with values ranging from low to high at 203.669 tons of carbon per pixel. Areas with high vegetation cover, such as urban forests and green open spaces, exhibited higher carbon concentrations compared to settlement areas and densely urbanized regions. Model evaluation conducted through field validation methods revealed a high correlation between model predictions and actual field conditions. This research demonstrates that the integration of GIS and remote sensing is effective for rapidly and accurately mapping and evaluating potential surface carbon stocks. Spatial information about carbon reserves is crucial as a basis for formulating sustainable environmental management policies and climate change mitigation strategies in Kendari City. The results of this study recommend wider adoption of this method to support spatial data-based environmental management in other regions across Indonesia

Abstract

The high temperature phenomenon is an event where the temperature in the city area is hotter than the surrounding area. Indonesia is located in a tropical climate, so several cities have the potential for temperatures to rise during the dry season. The city of Makassar is one of the cities with a high level of urbanization. With residents' enthusiasm for looking for work in the city, the land around the city has been converted into built-up land. Conditions like this make the existence of green open space uneven. This research aims is to determine the distribution of high-temperature phenomena through a spatial approach using remote sensing technology and geographic information systems. This research uses Landsat imagery for 2022 with the Land Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI), and Normalized Difference Built-up Index (NDBI) methods. The results of the research explain that the large number of existing buildings has caused an increase in urban temperatures, from an initial temperature of 29.93 oC to 39.51 oC.The increase in temperature occurs throughout the year, with the hottest peak temperature reaching 37 oC on April 15, 2022. The condition of vegetation density decreased by 0.05, starting from 0.66 in 2012 to 0.61 in 2022; this is in line with the increase in building area to 15,368 ha in 2022. This condition makes Makassar City one of the hottest cities in Indonesia. With an increasingly high need for built-up land and high mobility, it has the potential to accelerate temperature changes, so it is necessary to provide green open space in densely built areas by creating public open spaces. open private.
