Abstract

Currently, land cover data sourced from satellite imagery are increasingly being used with advances in sensing technology that are increasingly sophisticated. Maximum likelihood is one of the digital image classification methods that have long been used for pixel-based image classification. This study aims to classify land cover on Sentinel-2A satellite imagery using the maximum likelihood method to see the level of accuracy in that method. The accuracy test is carried out by comparing the results of the classification of the land cover map on the Sentinel-2A image with the sample in the High Resolution Upright Image with the acquisition date which is said to be Worldview and Geoeye imagery in 2019. From the classification results obtained an overall value of 90.81% with the type of land cover highest level of accuracy is wetlands and built-up areas. Meanwhile, the type of cover with the lowest accuracy or the most errors occurred in mixed garden types.

Abstract

The research area is located in South Leato, Dumbo Raya District, Gorontalo City. The research area is consist of Bone Diorite Formation which is in the miocene and the Pinogu Volcano Rock Formation which is in the quarter. The geological structure of the study area recorded in different rock formations is very interesting to be studied. The purpose of this study is to identify the types and general directions of geological structures that control the stress regime in the study area. This research method is in the form of field data collection and studio analysis. Data is collected by the field survey method. Analysis studio in the fracture processing data. Based on observations in the field, the geological structure contained in the study area is controlled by fracture. The type of fracture in the field is shear fracture. The results of the reconstruction of shear fracture in the study area is relatively northwest-southeast and north-south main direction.

Abstract

Coral reef mapping aims to see the distribution of coral reefs from 2000, 2010 and 2020. In addition, coral reef mapping also aims to see changes in the extent and damage of coral reefs from 2000, 2010 and 2020. The method used to detect the distribution of coral reefs is lyzenga logarithmic method, while to detect damage to coral reefs the method used is the unsupervised classification method. The lyzenga logarithm method uses attenuation coefficients based on the sharpening of the pixel spectral value to a certain depth to increase the value of the reflection of coral reef objects and the unsupervised classification method uses the sensitivity of the spectral values ​​of each pixel to coral reef objects. The results of the interpretation there was a significant change in the area of ​​coral reefs from 2000 to 2010 and 2010 to 2020. The interpretation of images from 2000 to 2010 detected a decrease in the area of ​​1.19 hectares. In 2010 to 2020 it detected a decrease in area of ​​28.87 hectares. The classification results detected an increase in the area of ​​damaged coral reefs from 2010 to 2020 as much as 8.74 hectares. The two methods used have differences in the level of accuracy, the lyzenga logarithmic method has an accuracy rate of 88.89% while the unsupervised classification method shows an accuracy of 86.12% so the lyzenga logarithmic method is the most suitable method for detecting coral reefs in Suwarnadwipa, Bungus Teluk District. Kabung City of Padang.

Abstract

Sebuah studi deskripsi komparatif dilakukan terhadap penggunaan AC pada kedua musim di Kota Gorontalo, yaitu musim kemarau dan musim penghujan. Tulisan ini bertujuan untuk mengetahui jika terdapat perbedaan penggunaan AC pada kedua musim secara spasial, yaitu berdasarkan per kecamatan di Kota Gorontalo. Maka disebarlah 157 kuesioner pada rumah tangga pada perumahan tipe 36 di 7 kecamatan yang ada. Mann Whitney digunakan untuk mendeskripsikan perbedaan penggunaan AC pada kedua musim dan SIG adalah sistem yang digunakan untuk melihat persebaran penggunaan AC pada kedua musim. Hasil menunjukkan bahwa saat musim kemarau sebanyak 88 % responden yang menggunakan AC pada kategori sering. Berbeda halnya saat musim penghujan, responden lebih dominan jarang (53,3%) menggunakan AC dibandingkan kategori sering. Kecamatan Kota Tengah dan Kecamatan Kota Selatan adalah kecamatan yang memiliki tingkat penggunaan AC tertinggi saat musim kemarau dan ketika musim penghujan kedua kecamatan mengalami penurunan pemakaian menjadi kategori jarang

Abstract

Teknologi penginderaan jauh saat ini berkembang sangat pesat seiring dengan perkembangan teknologi dibidang komputer, fisika, robotik dan artificial intelligence (AI). Teknologi tersebut kian berperan aktif dalam penggunannya untuk memperoleh informasi secara cepat dan efisien yang salah satunya terhadap penggunaan Unmanned Aerial Vehicle (UAV). Teknologi UAV ini merupakan sebuah pilihan terbaik dalam pengumpulan data geospasial secara cepat dengan harga terjangkau. Beberapa daerah atau kawasan di Indonesia memiliki keterbatasan akses terhadap citra satelit resolusi tinggi sehingga mempengaruhi terhadap keterlambatan memiliki data geospasial yang terupdate dengan informasi kewilayahan yang semakin lengkap. Seperti misalnya situs cagar budaya suatu kawasan bersejarah. Teknik pengumpulan data secara primer yang dilakukan secara pemotretan udara sebaran cagar budaya dengan mosaic foto untuk memperoleh kenampakan obyek secara keseluruhan. Hasil yang diperoleh berupa peta Orthophoto dari hasil pemrosesan yang memiliki informasi geospasial yang update serta dapat digunakan sebagai acuan perencanaan kebudayaan, pariwisata maupun pendidikan. Pada penerapan kali ini di Area A Warisan Dunia Tambang Batubara Ombilin Sawahlunto (WTBOS), diperoleh resolusi spasial sebesar 14 Cm dengan ketelitian geometri kelas 1 standar pemetaan dasar BIG sebesar 0,22 m pada kepercayaan 90% dan total RMSEr sebsar 0,33 m. Hasil ini diperoleh dari 61 titik yang terdiri dari GCP dan ICP dengan rata-rata tingkat ketelitian 10 mm (0.01 m).
