Abstract

Telah dilakukan penelitian untuk mendeteksi besar pergerakan tanah sebagai faktor pendorong penyebab terjadinya bencana longsor di Kota Padang.  Penelitian ini menggunakan data penginderaan jauh yakni data citra ALOS PalSAR tahun 2008 sampai 2009.  Metode yang digunakan dalam pengolahan adalah Differential Interferometry Synthetic Radar (DInSAR). Metode ini dapat mengamati pergerakan tanah terutama pada daerah perbukitan dengan ketelitian sentimeter.  Hasil penelitian menunjukkan besar pergerakan tanah untuk wilayah di Kota Padang berkisar antara 0,33- 3,04 cm/tahun.  Dari 11 kecamatan di Kota Padang, lima diantaranya yakni Kecamatan Pauh, Padang Selatan, Bungus Teluk Begalung, Koto Tangah dan Kuranji mengalami pergerakan atau pergeseran tanah yang cukup besar dari kecamatan lainnya yakni berkisar antara 0,825- 2,31 cm/tahun. Besarnya pergerakan tanah tersebut menyebabkan lima kecamatan di atas sering mengalami bencana tanah longsor dengan kategori cukup rawan. Research has been conducted to detect the magnitude of land movement as a driving factor for the occurrence of landslides in the city of Padang. This study uses remote sensing data namely ALOS PalSAR image data from 2008 to 2009. The method used in processing is Differential Interferometry Synthetic Radar (DInSAR). This method can observe the movement of the soil, especially in hilly areas with sub-centimeter accuracy. The results showed the amount of land movement for the area in Padang City ranged from 0,33 to 3,04 cm /year. Of the 11 districts in the city of Padang five of them namely the District of Pauh, South Padang, Bungus Teluk Begalung, Koto Tangah and Kuranji experienced substantial land movements or shifts from other districts which ranged from 0,825 to 2,31 cm /year. The magnitude of land movements and the high level of rainfall causes the five districts often experience landslides in quite vulnerable categories.

Abstract

Telah dilakukan penelitian tentang pemodelan spasial kebakaran hutan dan lahan di Provinsi Kalimantan Timur. Tujuan penelitian ini adalah mengidentifikasi faktor-faktor pemicu, membangun model spasial dan memetakan tingkat kebakaran hutan dan lahan yang terjadi di Provinsi Kalimantan Timur sebagai wilayah ibukota baru Indonesia. Pemodelan spasial kebakaran hutan dan lahan ini diambil dengan mempertimbangkan faktor manusia dan biofisik yang mempengaruhi kebakaran hutan dan lahan. Metode Composite Mapping Analysis (CMA) digunakan untuk mengembangkan model. Penelitian ini menemukan bahwa jarak dari jaringan jalan, jarak dari desa/permungkiman, keberadaan gambut, tutupan lahan dan curah hujan berpengaruh signifikan terhadap risiko kebakaran lahan dan hutan. Model spasial yang diperoleh dari penelitian memiliki koefisien determinasi 0,90. Validasi model menunjukkan bahwa model dapat memprediksi risiko kebakaran hutan dan lahan dengan akurasi 54,33 %. Model tersebut menggambarkan bahwa sekitar 54,5 % risiko kebakaran hutan dan lahan disebabkan oleh faktor manusia diantaranya jarak terhadap desa, jarak terhadap jalan dan tutupan lahan, sedangkan sisanya sebesar 45,5% disumbang oleh faktor biofisik diantaranya keberadaan gambut dan curah hujan. Spatial model of land and forest fire risk in East Kalimantan Province has been developed to identify the main causes of forest and land fires. The purpose of this study is also to build spatial models and map the level of forest and land fires in East Kalimantan Province as the candidate of new capital of Indonesia. The model was derived by considering human and biophysical factors that affect the forest and land fires. The Composite Mapping Analysis (CMA) method was used to develop the model. Distance from the road network, distance from villages/settlements, peatlands, land cover and rainfall have a significant effect on the risk of land and forest fires. The spatial model has a determination coefficient of 0.90. Model can predict the forest and land fire risk providing 54.33 % of accuracy. The model described that approximately 54.5 % of forest and land fire risk is contributed by human factors including distance to the village, distance to the road and land cover, while the rest of 45.5 %, is contributed by biophysical factors including peatlands  and rainfall.

Abstract

Penelitian ini membahas tentang perubahan tutupan lahan di Kalimantan terhadap temperatur permukaan. Identifikasi perubahan tutupan lahan dilakukan dengan metode analisa data satelit landsat pada setiap kelas tutupan lahan  yang bertujun untuk melihat kenaikan suhu permukaan. Klasifikasi tutupan lahan dan suhu permukaan didapatkan dari data landsat 5 dan 8 yang diolah dengan menggunakan ENVI 5.3 dan Arcgis 10.6 1. Klasifikasi tutupan lahan dibagi atas 3 kelas secara garis besar yaitu lahan terbangun, badan air, dan lahan non terbangun. Penelitian ini menemukan bahwa suhu permukaan pada setiap kelas tutupan lahan berbeda-beda. Perubahan pada tahun 1999 ke 2014 sebesar 7 % pada wilayah Kalimatan Timur, Kalimantan Selatan dan Kalimantan Barat. Hasil yang didapatkan menunjukkan perubahan tutupan lahan berbanding lurus dengan temperatur permukaan

Abstract

Nobita Hill, a tourist site in Padang City, is undergoing development as a tourist destination that offers a bird's-eye view of Padang City. Unfortunately, the hilly topography with steep slopes increases the risk of landslides in this area. In order to address the problem, the community service team from the Physics Department of Andalas University has carried out a six-month community service program from July to December 2022. It focused on disaster awareness education and used a qualitative approach. This activity aims to socialize disaster mitigation efforts, especially those related to landslides and earthquakes, considering that Padang City is also prone to earthquakes. The results of this activity showed an increase in the knowledge of the local community after the socialization, but repeated activities are needed to achieve optimal results. This ongoing activity is essential to ensure continuous improvement in the community's understanding of disaster mitigation and to support efforts to make Bukit Nobita a disaster-resilient area. Thus, this activity makes a positive contribution to shaping a safe, sustainable, and disaster-resilient tourism environment.

Abstract

We observed the effect of the La Niña phenomenon on the concentration of water vapor and ozone in the Indonesian region. This aims to the value of water vapor and ozone concentrations due to the La Niña phenomenon using Microwave Limb Sounder (MLS) data from 2004-2022. The La Niña phenomenon was chosen because during La Niña, the sea surface temperature in Indonesia is warmer than normal, thus increasing the evaporation of sea water which result is an increase in the concentration of water vapor in the atmosphere. Concentration values are observed at altitudes of (25.7;30.5;35.3;40.1) km because there are trends in water vapor and ozone concentrations at these altitudes. The La Niña phenomenon is used to see anomalies in water vapor and ozone concentrations from their normal state. La Niña phenomenon is observed based on the ONI index. We found that during La Niña, the water vapor concentration increased from its normal state while the ozone concentration decreased from its normal state. These two concentration values were used to find trends using Mann Kendall and Sen's Slope methods. We found that the trend of water vapor concentration is statistically significant while the trend of ozone concentration is the opposite.
