Mountains and hills (hereinafter referred to as mountains) are a special part of God’s creation. In addition to being mentioned in the Qur’an as being “bolts” of the Earth and water catchment areas, mountains are seen in a variety of religious and cultural traditions as being sacred and special places. There are thus many Asian literary works that boast of mountains existing in their locations. This paper seeks to examine why mountains are such an important element in the life of society by examining them in terms of their location and function. This study will use spatial information technologies such as Geographic Information System (GIS) to aid understanding of literary works, namely by taking the views of Harvey (1973) that “geographical space has a close relationship with the culture of a place”. Thus the location of an area will be linked to its function in terms of cultural space, social space, economic space, ideological space, and space movement. In this article, GIS will be used to map the location mountains that play a role in literary works to try to see the elements of space and the location of the mountain together with the cultural and narrative elements of the work. Among the literary works selected in which the location and function of these mountains will be observed are Sejarah Melayu (The Malay Annals), Hikayat Hang Tuah , Hikayat Seri Kelantan , Hikayat Seri Rama (Nusantara), Syakuntala (India), and Dewi Putih , as well as Liang Shan-Bo and Zhu Ying-Tai (China). Based on these works, it is found that mountains are important because they serve several functions such as the residence of rulers or spirits (ghosts, spirits, fairies); as a sacred place inhabited by the gods; as the source of the inheritance of kings; as places of study or for seeking spiritual and physical knowledge; as well as places that are rich in medicinal herbs. In the end, this essay shows that the nature of the mountains studied may explain the link between location and the culture of a certain race. Keywords : Geographic Information System, Sejarah Melayu , Global Positioning System, spirit, Asian Literature

Park and Ride (P&R) systems play a potentially important role in transportation planning to decrease the undesirable effects of private cars in the Central Business District (CBD). In order to achieve this objective, an essential component to be investigated is the catchment areas of these P&R facilities. However, a limited number of studies have applied the Geographic Information System (GIS) to study the spatial boundary accessibility of the catchment areas of P&R. This study aims to analyze the spatial boundary accessibility of the catchment areas of P&R facilities using three GIS methods. The first method uses geometric shapes to analyze the catchment areas of P&R facilities according to regular shapes, such as parabolas or circles. The market area is the second method used to analyze travel time via the tool ArcGIS Network Analyst to determine the catchment area of P&Rs. Finally, the dynamic accessibility method determines how accessible a facility can be through a study of the spatial boundary accessibility of P&Rs based on the travel time and distance between zones and P&R. The result shows that the static methods identify the spatial boundary accessibility through the calculation of the size of the shape of each P&R separately, while the dynamic method identifies the level of accessibility in detail for all P&R and also the accessibility of each zone to reach a facility. In conclusion, the dynamic accessibility method presents better accuracy than static methods in order to estimate the spatial boundary accessibility of the catchment area of P&Rs.

<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>

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.
