Buffel Grass

Buffel Grass Cenchrus ciliaris is a major environmental threat to biodiversity in central Australia and is rapidly expanding its distribution on National Parks and other areas of conservation concern. Managers need appropriate mapping of the potential and current Buffel Grass distribution at a broad landscape scale in order to prioritize their use of limited resources for survey and control efforts. Watarrka National Park was used as a case study to trial the effectiveness of aerial survey for mapping Buffel Grass distribution. Over 7 000 aerial observations were recorded from transects across the whole Park. Ground truthing indicated an acceptable level of accuracy for the aerial derived data at 84%, and a Kappa coefficient of 49. The aerial survey data were used to build a surface probability model for the entire Park based on environmental variables using Generalized Linear Modelling and then applied using a Geographic Information System. Distance to drainage and distance to tracks, followed by ruggedness, hummock grass cover and soil texture were the most important explanatory variables in determining the probability of occurrence of Buffel Grass. The surface model was overlaid with available vegetation mapping to quantify the level of threat to native plant diversity, in particular rare plant species diversity. This information is useful in developing a strategy for managing Buffel Grass at a landscape scale that is based on invasive potential and known biodiversity values, where previous management has focused on small scale site specific control actions.

<p>Erupsi Gunungapi Merapi tahun 2010 mengakibatkan banyak korban jiwa, kerusakan aset dan kerugian di berbagai bidang. Untuk meminimalkan korban jiwa, kerusakan dan kerugian, diperlukan upaya pengurangan risiko bencana (PRB). Salah satu upaya yang dilakukan adalah program desa bersaudara (<em>sister village</em>) yang digagas oleh Pemerintah Kabupaten Magelang melalui Badan Penanggulangan Bencana Daerah (BPBD). Program desa bersaudara ini bertujuan agar ada kepastian tempat pengungsian, mengurangi kesemrawutan proses pengungsian serta memudahkan pelayanan pengungsi. Program ini dapat memanfaatan Sistem Informasi Geografis/<em>Geographic Information System</em> (GIS) yang berbasis web (<em>WebGIS</em>). <em>WebGIS</em> mampu mendiseminasikan peta yang dihasilkan dalam program desa bersaudara, misalnya peta jalur evakuasi. Makalah ini bertujuan untuk mendiskripsikan pemanfataan <em>WebGIS</em> dalam mendukung program desa bersaudara, dengan mengambil kasus di Desa Ngargomulyo (desa rawan bencana) dan Desa Tamanagung (desa penyangga/ penerima pengungsi). Metodenya adalah memaparkan proses pemetaan jalur evakuasi. Proses penyusunan peta tersebut terbagi empat tahap:   survei lapangan, penyiapan data spasial, coding dan publikasi. Hasilnya adalah tampilan peta jalur evakuasi yang bisa diakses oleh siapapun tanpa menggunakan aplikasi GIS yang memudahkan masyarakat pengungsi, penerima pengungsi, pemerintah maupun parapihak, mengetahui asal pengungsi, jalur evakuasi dan titik pengungsian. Penelitian ini menyimpulkan bahwa pemetaan <em>WebGIS</em> dapat mendukung upaya PRB dengan keunggulan bisa dijangkau pengguna secara sangat luas.<strong></strong></p><p><strong>Kata kunci</strong>: desa bersaudara, <em>sister village</em>, pemetaan jalur evakuasi, <em>gis</em>, <em>webgis</em></p>

High Population

District of West Padang which is the area closest to the coast and has a high population. Therefore a geographic information system was created using the A-Star Algorithm method. The A-Star algorithm uses the closest distance estimation to reach a goal and has a heuristic value that is used as a basis for consideration. In this system there are alternative paths and show the amount of capacity and distance from the shelter to be addressed.
