Perubahan lahan permukiman di area perkotaan mempengaruhi perubahan iklim mikro di area kota. Penelitian ini bertujuan untuk mengidentifikasi perubahan suhu permukaan darat yang dipengaruhi oleh perubahan penggunaan lahan, kondisi vegetasi dan kepadatan bangunan di Kota Bukittinggi penelitian ini menggunakan data citra satelit landsat ETM 5 tahun 2011 dan citra satelit landsat OLI 8 tahun 2017. Metode yang digunakan dalam penelitian ini menggunakan klasifikasi maximum likelihood, Normalized Difference Vegetation Index, Normalized Difference Build-up Index, dan land surface temperatur yang dirposes menggunakan teknologi geospasial. Hasil penelitian menemukan bahwa dari rentang tahun 2011 ke tahun 2017 telah terjadi perubahan penggunaan lahan (43,9 ha) yang tidak terlalu luas di Kota Bukittinggi akan tetapi fenomena ini sangat berpengaruh besar terhadap dinamika suhu permukaan darat dimana dalam rentang 6 tahun terakhir suhu permukaan darat telah meninggkat sekitar 4,567 oC peningkatan suhu ini dipengaruhi oleh tingkat kepadatan bangunan di Kota Bukittinggi dan kondisi vegetasi yang sangat minim pada area pusat kota yang menjadikan lingkungan di sekitar area kota menjadi sangat panas setiap tahunnya.

Danau Maninjau merupakan danau vulkanik dengan kondisi air berupa air tawar. Penelitian ini bertujuan untuk memetakan kedalaman perairan pada kawasan Danau Maninjau Kabupaten Agam dan menilai pengaruh dari distribusi sampel lapangan pada kualitas hasil transoformasi citra. Data yang digunakan citra satelit Sentinel 2A, titik hasil pengukuran lapangan. Teknik analisis menggunakan algoritma Normalized difference water index, sun glint, Emperical Batimetri Methode dan regresi linear. Hasil dari penelitian ditemukan variasi distribusi kedalam peraian dari proses perekaman kedalaman objek yang direpresentasikan oleh piksel citra, yang mana kedalaman perairan dari hasil transofmrasi ini mengacu pada sampel pengukuran di lapangan. Kedalaman maksimum perairan danau berada pada rentang 107m. Perairan dangkal lebih dominan terdistribusi diwilayah utara perarian yang merupakan outlate dari Danau Maninjau. Sedangkan diwlayah selatan membentuk cekungan dalam. Distribusi sampel ini berupa peta empirical batimetri serta hubungan antara hasil pengukuran lapangan dengan transformasi dengan nilai regresi 0.769, ini menujukan sampel lapangan memberikan pengaruh yang cukup besar pada hasil transofrmasi

Dimulai revolusi industri 4.0 terjadinya perkembangan teknologi yang sangat pesat salah satunya dibidang informasi geospasial. Pemanfaatan teknologi sistem informasi geografis (SIG) sudah merambah pada berbagai aspek kehidupan. SIG juga sangat berkontribusi dalam perkembangan peradapan di kota-kota besar yang telah bertransformasi menjadi smart city. Keterbukaan informasi merupakan bahagian utama yang menjadi sasaran perkembangan smart city. Tujuan dalam penelitian ini untuk mengengaplikasikan dan mengembangkan teknologi SIG berbasis Web Map dalam memetakan perseberan pasien covid 19 di Provinsi Riau. Melakukan uji kecepatan browser untuk mengakses web map informasi Covid 19. Dalam penelitian ini dilakukan inventaris data berbasis cloud data spasial, perangkat yang digunakan berupa ArcSIGPro untuk membangun webmap. Hasil dari penelitian ini ditemukan perkembangan jumlah pasien Covid-19 yang terus berkembang setiap waktu, yang direpresentasikan dalam informasi lokasi. Tampilan akir web map ini dapat di akses melalui link https://bit.ly/31EKXSW. Penggunaan WebSIG ini mampu memamaparankan informasi covid dengan sistem webmap lebih efisien untuk mengetahui spot –spot yang memiliki jumlah korban yang relative tinggi, secara umum untuk kesemua jenis kasus Covid-19 tersebar banyak kasus pada wilayah administrasi Kabupaten Rokan Hulu, Rokan Hilir, Indragiri Hulu dan Indragiri Hilir. Sedangkan untuk kasus positive covid-19 terbesar tersebar di wilayah Kota Pekanbaru dengan jumlah 40 orang.

One of hindrances faced by Indonesia agriculture sector is domestic agriculture production that does not cover the market demand such as wheat commodity. The aim of this research is to calculate the spatial planning for wheat commodity in Tanah Datar Regency by using matching calculation with Fuzzy set method to find out the land physical ability. The method used in this research using fuzzy set equations and Boolean approach. The research results obtain land suitability 111.132 ha for suitable category, 20.239 ha for quite suitable, and 137 m2 for unsuitable category. Then after the land suitability is obtained, development instruction is given for the agriculture planning of wheat commodity with Boolean approach. The result of development instruction reaches 42.873 ha spread in all over sub districts with the highest development potency is at North Lintau Buo Sub District 9.657 ha and Lintau Buo Sub District 7.348 ha. This development potency can be used as the initial reference for planting wheat commodity (Triticum aestivum) in Tanah Datar Regency.

UTILIZATION OF REMOTE SENSING FOR LAND SURFACE TEMPERATURE (LST) DISTRIBUTION MAPPING IN SOLOK CITY IN 2021 Mutiara Fitri; Triyatno Triyatno

Solok City is one of the cities in West Sumatra which has a fairly rapid population growth, this has led to an increase in development and a decrease in green open land or vegetation land. This affects the ground surface which absorbs and reflects more of the sun's heat. These conditions have an impact on rising surface temperatures. This research was conducted to analyze changes in vegetation land, built-up land and changes in surface temperature in Solok City using Landsat-8 Imagery of Solok City in 2015 and 2021 using the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-up Index (NDVI) algorithm models. (NDBI) and Land Surface Temperature (LST). The results of the study explain that the normalized difference vegetation index (NDVI) in Solok City has decreased, in 2015 the area of vegetation density was 2344 Ha and in 2021 it was reduced to 1888 Ha. This is in line with the increase in building area / Normalized Difference Built-up Index (NDBI) in 2015, namely 1 from 921 Ha to 2295 Ha in 2021. Reduced vegetation area and increased built-up area increased Land Surface Temperature (LST) in the area. research, the temperature in 2015 was around 32.9° C and in 2021 there was an increase in surface temperature to 33.6° C. Pearson product-moment correlation was carried out to see the level of relationship between LST and NDVI and NDBI.

This type of research is quantitative descriptive, with image interpretation through high-resolution images, and primary data as a source of data obtained through field surveys. The technique for determining informants is Total Sampling. The population in this study are villages in the Koto Tangah District, Padang City. This analysis uses quantitative analysis, namely on-screen digitization using the Arcgis application. Based on the results of research and discussion on High-Resolution Image Interpretation for Identification of Irrigation Channel Damage in Kasang and Kapalo Hilalang, Koto Tangah District, Padang City, the results obtained, namely the identification of irrigation canals using high-resolution imagery produces sufficient data in accordance with the conditions field. Based on the field survey, the condition of the network damage for the Hilalang Headquarters, starting from the weir building to BKH 1 was heavily damaged, BKH 2 to BKH 6 was moderately damaged. Starting from BKH 7 to BKH 8 still has good conditions. While the condition of the Kasang II irrigation canal from the weir to BKD 5 is still in good condition. BKD 6 to BKD 7 is moderately damaged. In contrast to BKD 4, it is in good condition, while parts of BAA 1 to 3 are in moderately damaged condition. The shape of the irrigation image in the city of Padang is tortuous, this is influenced by the topography of the area around the river which consists of community rice fields. The pattern shown in the image of the irrigation canal in the city of Padang is elongated, this shows the flow of the river from the upstream area to the downstream area of the river. The texture that is displayed in the image of the irrigation canal in the city of Padang has a smooth texture. The site shown in the image of the irrigation canal in the city of Padang is side by side with the rice fields belonging to the community in the Koto Tangah District.
