Abstract

This research examines the interpretation of built-up areas on Sentinel-2 imagery using interpretation keys and recognizes the appearance of slums from remote sensing data. The use of interpretation keys in visual interpretation is the first step for interpreters to recognize objects in the image. The research objectives were: 1) to interpret built-up areas; 2) to recognize slum conditions based on visual interpretation of sentinel-2 imagery and; 3) to determine the affordability of remote sensing data for slum parameters. The method used is a visual interpretation that is carried out in stages on the classification of built-up areas and settlements. The introduction of slum conditions is done by object interpretation in slum delineation. The result of this study is the mapping of built-up areas in Semarang City from the visual interpretation method obtained an accuracy of 87.5%. The effective use of interpretation keys at the land cover interpretation level are shape, pattern, size, and color. The condition of slums with remote sensing is visually depicted on the key interpretation of shape and pattern. The affordability of remote sensing data for slum parameters has limitations. The ability to extract remotely sensed data for slum parameters can help narrow down field studies in assessing slum parameters.

Abstract

Kabupaten Muaro Jambi merupakan kabupaten dengan intensitas kebakaran hutan dan lahan tertinggi di Provinsi Jambi. Pada tahun 2019 terjadi kebakaran hutan dan lahan terbesar di Provinsi Jambi, khususnya Kabupaten Muaro Jambi yang mengakibatkan fenomena langit memerah akibat tebalnya kabut asap kebakaran. Pemetaan keparahan kebakaran hutan dapat dilakukan secara efisien memanfaatkan teknologi penginderaan jauh karena mampu menghemat waktu, biaya, dan tenaga. Citra Landsat 8 digunakan pada penelitian ini sebagai input untuk melakukan transformasi indeks Normalized Burn Ratio (NBR). Indeks NBR memanfaatkan saluran NIR dan SWIR yang mampu membedakan area terbakar dengan baik. Selisih antara nilai NBR sebelum dan NBR sesudah kebakaran akan menghasilkan informasi berupa tingkat keparahan kebakaran hutan dan lahan di Kabupaten Muaro Jambi. Hasil penelitian ini menunjukkan bahwa tingkat keparahan kebakaran pada tahun 2019 – 2020 didominasi oleh kelas keparahan rendah namun terjadi masif. Selanjutnya pada periode tahun 2019 – 2021 area-area yang terbakar sudah mengalami proses pertumbuhan vegetasi yang tinggi.

Abstract

Land cover information is an essential aspect in the planning and management of earth modeling and understanding. Land cover changes impact the physical and social environment, such as hydrological conditions and ecological systems. This study aimed to identify spatial differences in the land cover of the Batur catchment area from 2015-2021 by using a remote sensing approach to describe the existing land-cover site and to detect its changes. The methods used in this study are a combination of the vegetation index and a supervised classification maximum likelihood algorithm with Landsat 8 OLI/TIRS in 2015 and 2021. Furthermore, the Change Detection Feature, identified from two image periods in 2015-2021 and processed, is used to detect changes in land cover. The accuracy assessment utilized QuickBird imagery recorded in 2015; field survey data were taken in 2021. The results showed that between 2015 to 2021, built-up area, bare land, shrubs, and lake have increased by 102,66% (306,01 ha), 27,95% (452,25 ha), 15,20% (215,72 ha) and 4,05 % (62,73 ha) while dryland forest and dry-dry-field have decreased by -25,84% (-606,29 ha) and -14.59% (-430,42 ha), respectively. The overall accuracy of the multispectral classification results in 2015 and 2021 was 82,63% and 89,57%.Keywords: Land-Cover Change; Batur; Catchment Area; Remote Sensing

Abstract

Perubahan alih fungsi lahan di Kabupaten Muaro Jambi terjadi secara masif, terutama akibat pembukaan lahan baru melalui metode pembakaran. Kebakaran hutan terbesar tercatat pada tahun 2019, menyebabkan gangguan ekosistem yang berlangsung beberapa tahun di Kabupaten Muaro Jambi. Net Primary Productivity (NPP) menjadi indikator kunci untuk mengukur dampak perubahan lingkungan, menjadikan studi ini sangat penting untuk pemantauan perubahan iklim dan pembangunan ekologi yang berkelanjutan. Umumnya NPP dihitung secara bulanan atau tahunan, namun perkembangan teknologi penginderaan jauh dapat digunakan untuk mengestimasi NPP dengan efektif dan efisien pada tingkat lanskap hingga tingkatan temporal yang pendek. Model CASA, yang umum digunakan, memanfaatkan radiasi efektif fotosintesis vegetasi dan energi cahaya aktual untuk memperkirakan NPP. Penelitian ini bertujuan mengaplikasikan model CASA untuk menghitung NPP harian di Kabupaten Muaro Jambi akibat kebakaran tahun 2019. Penelitian ini menghasilkan perhitungan nilai NPP harian dalam satuan gC/MJ-1 yang disesuaikan dengan waktu perekaman citra Landsat terbersih setelah kebakaran hutan tahun 2019.

Abstract

Total Suspended Solid (TSS), as one of the physical parameters of water quality, can also become an indicator in more comprehensive research themes. TSS is closely related to the process of erosion and sedimentation. One of the reservoirs that is experiencing serious problems with sedimentation is WGM. In terms of physical changes, alterations in water quality involve the introduction of both organic and inorganic solid particles, leading to elevated water turbidity and diminished penetration of sunlight into the water body. Remote sensing techniques can indirectly estimate and map TSS in bodies of water. Landsat imagery has been widely used in TSS studies. Not only is it able to identify water turbidity, but it also has a long time series and convenient data accessibility. The purpose of this research is to examine the TSS equation in the form of Normalised Suspended Material Index (NSMI) and the Syarif Budhiman Algorithm to obtain a comparison of results that are suitable for application to the waters of WGM using Landsat imagery. The results showed that the Syarif Budhiman Algorithm is considered more suitable to be applied to the study site based on statistical analysis using Landsat image data and field TSS sample data. The accuracy test results for the two equations did not show significant differences. The Syarif Budhiman equation showed a value of 37.87, and the NSMI equation of 37.47. However, the coefficient of model determination was 0.251 for NSMI and 0.340 for Syarif Budhiman. The distribution of TSS at the study site is generally homogeneously distributed with small concentrations ranging from 0-20 mg/L in the middle side of the reservoir. While the TSS class > 100 mg/L is scattered on the edge of the reservoir in Pondok, Keduang, Kepuh Wiroko, Temon, Bengawan Solo Hulu, Alang, and Kedungguling sub-watersheds

Abstract

Indonesia's national sugar demand continues to increase, while domestic production is still limited due to the lack of accurate data on the area and type of sugarcane cultivation. To address this issue, this research utilized the Random Forest (RF) algorithm on PlanetScope satellite imagery to classify the types of sugarcane cultivation, i.e. early planted sugarcane and pressed sugarcane. This study offers a more detailed approach than previous studies by dividing sugarcane based on its growth cycle into two main classes: < 3 times and ≥ 3 times. The results showed that the Random Forest (RF) method was able to increase the mapping accuracy to 94.52%, higher than conventional methods which are generally in the range of 85-91%. Of the three classification schemes tested, Scheme 3 produced the best performance with an accuracy of 94.52% and a Kappa coefficient of 43.87%. The mapping results also revealed that sugarcane cultivation of ≥ 3 squeezes dominated the study area with 93.08% coverage of the total sugarcane land, while sugarcane of < 3 squeezes only covered 7.55%. The difference between the classification results and the field data shows that the imbalance in the number of samples and spectral similarity between classes are the main challenges in mapping sugarcane cultivation. This finding proves that the Random Forest algorithm with PlanetScope images can significantly improve the accuracy of sugarcane cultivation type mapping compared to previous methods. The results of this study make an important contribution in providing more accurate spatial data to support sugarcane production estimation, optimization of plantation management, and strategic planning in achieving national sugar self-sufficiency.

Abstract

Ruang Terbuka Hijau (RTH) adalah ruang terbuka bervegetasi dengan fungsi yang beragam. Namun, seiring berkembangnya lahan terbangun menyebabkan keberadaan RTH semakin berkurang. Penelitian ini bertujuan untuk mengetahui akurasi informasi RTH yang diperoleh dari interpretasi visual citra Planet di Kecamatan Sewon, mengetahui ketersediaan RTH berdasarkan kepemilikan, dan mengetahui ketersediaan RTH berdasarkan kebutuhan oksigen. Data penginderaan jauh yang digunakan adalah citra Planet sedangkan data sekunder berupa jumlah penduduk, jumlah kendaraan, dan jumlah hewan ternak. Metode yang digunakan dalam penelitian ini adalah interpretasi visual pada citra Planet, metode Gerarkis, dan Confusion Matrix. Hasil penelitian menunjukkan bahwa citra Planet dapat digunakan untuk memperoleh informasi RTH dengan akurasi 87.1%. RTH di Kecamatan Sewon berdasarkan status kepemilikan publik sebesar 11.11% dan privat 25.47% sehingga perlu dilakukan penambahan RTH publik. Selain itu, kebutuhan RTH berdasarkan metode Gerarkis menunjukkan bahwa oksigen sudah terpenuhi. Pemetaan RTH menggunakan citra Planet dapat dijadikan sebagai data masukan dalam perumusan kebijakan lingkungan dan perencana kota, yaitu merancang tata ruang yang berkelanjutan serta memperhitungkan keberadaan dan kebutuhan RTH di masa depan.

Abstract

Dengue haemorrhagic fever (DHF) is one of the infectious diseases transmitted through the mosquito vector Aedes sp. Dengue disease management is still aimed at controlling the vector (Aedes aegypti) using organophosphate insecticides malation and temefos. In Magetan District, there is no report on the resistance of Ae. aegypti to organophosphate insecticides or mapping of Ae. aegypti resistance to these insecticides. The results of this research are determine the resistance of Ae. aegypti to organophosphate insecticides. The resistance system was established by biochemical test based on the activity of non-specific esterase enzyme against organophosphate insecticides in Magetan District using Arc GIS tool. The results of this study showed that Ae. aegypti in four working areas of Candirejo Health Centre from 14 villages 10 villages (71.42%) have been resistant to organophosphate insecticides, while in Taji from 11 villages 7 villages (63.63%) are resistant, in Plaosan 100% are resistant and in Ngujung from 7 villages, 3 villages (42.28%) are resistant.  The use of insecticides for a long period of time is not effective in eliminating dengue fever vectors because it can cause resistance. Based on the results of this study, it is necessary to monitor and evaluate the use of insecticides in dengue vector control as a programme at the Magetan District Health Office, so that the right insecticide can be selected for Ae. aegypti control.
