"Rajasthan is a semi arid state with the highest of the geographical area (343,000.00 square km) of the Indian subcontinent. Annual rainfall variation is very high over the state ranging from 100 mm to 1000 mm from west to south/east. Matter of water resources planning is of prime importance for the state. There are 237 blocks, out of which 200 blocks are declared as dark zone due to over exploitation of ground water. In these circumstances, it becomes necessary to plan the storage and uses of surface as well as subsurface water (conjunctive use) with maintaining the ecological sustainability. Surface water reservoirs are becoming dry year after year. It was observed from the annual storage data of the dams that water inflow is declining year after year due to various reasons like changes in land use and land pattern, change in hydro geological conditions, changes in environmental factors e.g. temporal and spatial distribution of rainfall, indiscriminate infrastructural development. Due to less water inflow in the dams and increase in the number of dark zone blocks, state is facing the water stress problem. With the increasing population, it will become more severe with the passage of time. Therefore, an effort is being made through this research to test the hypothesis whether there is an appreciable change in water inflow in the dams of Rajasthan state. A total of 115 nos of major & medium dams in the state have been selected by cluster sampling to test the hypothesis. Chi Square test has been conducted for testing the hypothesis and found that there is declining trend of water inflow in the dams and dependabilities of the river basins have been reduced."

"ABSTRAKSejak 1960an geograf mulai menggunakan mental maps yang digambarkan pada kertas untuk melakukan studi mengenai ruang. Kemunculan fenomena Volunteered Geographic Information VGI pada abad ke-21 mempersembahkan jenis data baru yang bisa digunakan oleh geograf dalam meneliti ruang. Penelitian ini bermaksud untuk membandingkan akurasi antar kedua data tersebut menggunakan konsep produk spasial. Agar bisa dibandingkan, diperlukan partisipan yang bersedia untuk mengisi webmap untuk mendapatkan VGI , print-out peta cetak, dan mental mapsnya. Mahasiswa Universitas Indonesia yang tinggal di Kelurahan Kukusan dipilih sebagai partisipan penelitian. Mereka diminta untuk memetakan tiga tempat makan favoritnya di Kelurahan Kukusan sebagai strategi untuk mengidentifikasi tempat makan populer sekaligus mengungkap mental maps mereka. Total ada 142 responden mengisi webmap yang menghasilkan VGI berupa 419 titik tempat makan favorit beserta penilaian karakterstiknya. Dari 142 responden, 13 diantaranya bersedia mengisi peta print out peta cetak sehingga keduanya bisa dibandingkan. Dari data VGI, tiga tempat paling populer di Kelurahan Kukusan yang berhasil diidentifikasi adalah Cumlaude, Bahari, dan Samtari. Secara umum, tempat makan populer diingat sebagai tempat yang memiliki akses dan fasilitas baik; sedangkan yang tidak begitu populer memiliki karakteristik harga yang pas, lingkungan yang nyaman, dan penduduk sekitar yang ramah dibanding tempat yang populer. Dari hasil perbandingan, tidak ditemukan adanya perbedaan antara VGI dengan data yang diperoleh melalui peta cetak di kertas. Meskipun begitu, ada temuan yang mengindikasikan bahwa terdapat hubungan antara akurasi VGI dengan mental maps yang menarik untuk diteliti lebih lanjut.

ABSTRACTIn the 1960s, geographer started to use mental maps that are drawn in a paper to study places. The emerging of Voulnteered Geographic Information VGI in the 21st century presents geographer a new data to study places. This research are are an attempt to compare those two by using spatial product concept. To compare those two, there must be a willing person as a participant of this research, to draw on a webmap to obtain VGI and paper map, and their mental maps. Students in the University of Indonesia that lives temporarily in Kelurahan Kukusan are choosen as the participant. They rsquo re asked to identify three of their favourite eating place in Kukusan as a strategy to identify popular eating place and to obtain their mental maps. In total, there are 142 participants filling up the webmap, creating a VGI map of 419 favourite eating spots in Kukusan with their ratings about the places characteristic. From the 142, 13 of them are willing to fill their paper map so that the two data can be compared. From the VGI, the three most popular eating places are identified as Cumlaude, Bahari, and Samtari. In general, popular eating places are remembered to have good accessibility and facility and the not so popular ones are remembered to have more suitable prices, comfortable environment, and friendly peoples than the popular ones. There is no difference in between the accuracy VGI and the accuracy of data obtained by print map. But, there seems to be an interesting relationship between the accuracy of VGI with the mental maps that should be researched further."

"In recent economic geography, it is emphasized that the effect of cost decreasing in transportation on agglomeration is nonlinear. It is said that the influence of traffic infrastructure investment and the change in transportation cost on urban agglomeration does not appear until the cost is below a certain amount and that nce agglomeration arises that effect would be kept with higher probability....."

"Penelitian mengenai Nudibranchia di terumbu karang Pulau Pramuka dan Karang Lebar, Taman Nasional Laut Kepulauan Seribu telah dilakukan pada bulan November dan Desember 2000 serta bulan Januari 2001. Sebanyak 18 jenis Nudibranchia (4 Suku) ditemukan tersebar pada kedalaman 20-80 kaki (6-25 meter). Jenis-jenis dari suku Phyllidiidae (13 jenis) merupakan jenis yang paling sering dijumpai dan paling banyak jumlah individunya serta tersebar di berbagai kedalaman. Secara umum, jenis jenis Nudibranchia paling banyak dijumpai di kedalaman 50-60 kaki. Jumlah jenis Nudibranchia yang ditemukan akan menurun pada kedalaman yang kurang (20-40 kaki) dan lebih (70-80 kaki) dari 50-60 kaki. Pengamatan pemangsaan salah satu jenis Nudibranchia memberikan hasil catatan pertama (first record) pemangsaan Phyllidia varicosa terhadap sponge Axinyssa cf. aculeata. Teramatinya bekas pemangsaan pada sponge juga merupakan catatan pertama (first record)."

"Daftar nama tempat, nama benda maupun nama orang yang dipetik dari Babad Pasir. Nama-nama tersebut diberi keterangan dalam bahasa Belanda, disebutkan juga pupuli dan halaman asal nama tersebut dipetik namun tidak diketahui data naskah yang dipetik. Melihat corak tulisannya, naskah ini kemungkinan dikerjakan oleh Pigeaud sendiri pada tahun 1926. Keterangan bibliografis mengenai Babad Pasir dapat dibaca pada Pratelan II: 170; dan Pigeaud 1970: 340."
