Abstract

Temperatur udara permukaan di Sumatera Barat telah diteliti menggunakan data stasiun Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) untuk 11 tahun pengamatan (2007 – 2017) di empat lokasi, yaitu Teluk Bayur (Padang), Minang Kabau (batas kota Padang – Padang Pariaman), Sincincin (Padang Pariaman) dan Padang Panjang. Selain itu digunakan juga data re-analisis dari European Centre for Medium-Range Weather Forecasts Re-Analysis interim model data (ECMWF ERA-Interim) untuk 38 tahun pengamatan (1980 – 2017). Osilasi internal temperatur udara permukaan di Sumatera Barat diamati menggunakan transformasi wavelet dengan mother Maxican Hat. Hasil penelitian menunjukkan bahwa temperatur udara permukaan rata – rata di Sumatera Barat meningkat sekitar 0,007⁰C-0,01⁰C/tahun. Temperatur maksimum harian meningkat sekitar 0,058⁰C-0,066⁰C/tahun, sedangkan temperature udara minimum harian meningkat sekitar 0,028⁰C-0,045⁰C/tahun. Periode ulang temperatur udara permukaan di Sumatera Barat yang paling dominan adalah satu tahun, atau biasa disebut osilasi tahunan yang disebabkan oleh monsun. Selain itu, terdapat osilasi 4 dan 8 tahun yang bersesuaian dengan siklus El-Nino Southern Oscillation (ENSO). Dengan demikian dapat dikatakan bahwa temperatur udara permukaan di Sumatera Barat dipengaruhi oleh monsun dan ENSO. Kata kunci: Temperatur udara permukaan, Sumatera Barat, ERA-Interim, monsun, ENSO

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

The Bright band (BB) observation can be used as an indication of the melting layer height. Measurement of BB from Normal Scan (NS) on Global Precipitation Measurement (GPM) had been compared with Micro Rain Radar (MRR), which is installed in Kototabang, West Sumatera (0.23° S; 100.32°E; 865 m above sea level). The GPM data were collected from December 2014 to June 2018 and compared with MRR observation from January 2012 to August 2016. The BB values from these instruments were compared with those recommended by the International Telecommunication Union Recommendation (ITU-R) P.839. The BB from GPM and MRR showed slightly diurnal and seasonal variations. BB observations from GPM and MRR show good agreement with slight diurnal and seasonal variations differences. BB observations are more similar when the intensity of solar radiation is lower, i.e., at night (18.00-24.00 LT) until early morning (00.00-06.00 LT). Furthermore, MRR showed a slight bimodal pattern in the seasonal variation, while GPM did not. Thus, the seasonal variation in the observation of both instruments is different. The most significant difference from the seasonal variation was observed in the summer season (June-August (JJA)). The mean BB of the two instruments is lower than the Freezing Height Level (FHL) value calculated from the ITU-R model. However, many BB from the two instruments (>36 %) have a BB altitude higher than FHL. Thus, the constant assumption of FHL in West Sumatera for the rain attenuation estimation of microwaves may not be appropriate.

Abstract

Nobita Hill is one of the areas being developed as a tourist attraction in the city of Padang. Above Nobita Hill is a beautiful view, and you can see the picture of Padang City. However, the hilly topography with steep slopes makes this area prone to landslides. This activity aims to map the potential for landslides on Novita Hill. Activities start from preparation, implementation in the field, and evaluation. Field activities are carried out in two stages. The first stage is an experiment to map the landslide potential. The second stage is socialization. The target audience for this activity is the Village Head of Jua Nan XX Village and its officials and the community around Nobita Hill. The results of the study and mapping were disseminated to the village administration and community leaders involved in the development of the Bukit Nobita tourism area, which was carried out on November 16, 2022. The result of tourist objects often changes land use and cover. However, mitigation of the potential for landslides in this area has never been done. Therefore, the Andalas University Physics Department team mapped the potential for landslides on Novita Hill for six months, using microseismic and geoelectric methods. This activity obtained a map of the distribution of dominant frequencies, a map of the distribution of amplification, and an identification of slip planes concerning the potential for landslides on Nobita Hill. Furthermore, the results of the mapping and mitigation efforts have been disseminated to the village administration and community leaders involved in the development of the Bukit Nobita tourism area. This activity was carried out well. The landslide potential distribution map obtained from this activity is input for the community and stakeholders in developing the Buki Nobita tourist attraction that is safe from disasters.
