Growth of graphene on 6H-SiC by molecular dynamics simulation

Classical molecular-dynamics simulations were carried out to study epitaxial growth of graphene on 6H-SiC(0001) substrate. It was found that there exists a threshold annealing temperature above which we observe formation of graphitic structure on the substrate. To check the sensitivity of the simulation results, we tested two empirical potentials and evaluated their reliability by the calculated characteristics of graphene, its carbon-carbon bond-length, pair correlation function, and binding energy.Comment: 7 pages, 5 figure

Public Perception on Historical Landscape of Ethnic Immigrant Heritage in Heritage City of Baubau

As a one of the heritage cities in Indonesia, Baubau has many historical heritages which are not only created by local ethnics but also by immigrants. There are three historical landscapes created by the immigrants like China Town by Chinese, Waliabuku by Bugisnese, and Ngkaring-Ngkaring by Balinese. Until now, proper management to preserve the landscapes does not exist and it remains unknown whether this phenomenon is caused by the public perception who think that historical landscapes of immigrants as an unimportant heritage. The objective of this study is to investigate the public perception of historical landscapes that are created by immigrant in Baubau city as an heritage city in Indonesia. The results of survey show that the public regard all historical landscapes must be preserved. However, the landscapes created by the ethnic of Chinese have the lowest degree of public selection as compared to the ethnics of Bali and Bugis. The situation is triggered by the stereotype on the ethnic of Chinese which state that they tend to be more closed and reserved. Sebagai salah satu kota pusaka di Indonesia, Baubau memiliki banyak peninggalan sejarah bukan hanya yang dibentuk oleh etnis lokal, tetapi juga oleh etnis pendatang. Setidaknya terdapat tiga lanskap sejarah yang dibentuk oleh etnis pendatang yaitu lanskap pecinan oleh etnis Tionghoa, lanskap Waliabuku oleh etnis Bugis, dan lanskap Ngkaring-Ngkaring oleh etnis Bali. Sampai saat ini belum ada pengelolaan untuk melestarikan ketiga lanskap tersebut dan belum diketahui apakah fenomena ini dipengaruhi oleh persepsi masyarakat yang merasa lanskap peninggalan etnis pendatang tidaklah penting? Tujuan penelitian ini yaitu mengkaji persepsi masyarakat terhadap lanskap sejarah peninggalan etnis pendatang sebagai aset pusaka Kota Baubau sebagai kota pusaka Indonesia. Hasil yang diperoleh dari survei yang dilakukan, masyarakat umumnya menganggap seluruh lanskap sejarah harus dilestarikan tidak memandang apakah dibentuk oleh etnis lokal atau pendatang. Meskipun demikian, lanskap yang dibentuk oleh etnis Tionghoa memiliki derajat pemilihan paling rendah dari lanskap yang dibentuk etnis Bali dan Bugis. Hal ini disebabkan oleh adanya stereotip akibat karakter etnis Tionghoa yang dianggap masyarakat cenderung tertutup di Kota Baubau

Integrating an agent-based model of malaria mosquitoes with a geographic information system

Agent-based models (ABMs) are used to model infectious diseases and disease-transmitting vectors. Malaria is a deadly infectious disease in humans, transmitted by Anopheles mosquito vectors. Although geographic information system (GIS) has been used before with ABMs, no ABM-based malaria study showed the usage of custom-built spatial outputs integrated within a modeling framework. In this paper, we show how to effectively integrate a malaria ABM with GIS-based, spatially derived parameters. For a specific study area, we process GIS data layers, create hypothetical scenarios, produce maps, and analyze biological insights. Results indicate that availability of resources and relative distances between them are crucial determinants for malaria transmission. The maps also reveal potential hotspots for the measured variables. We argue that such integrated approaches, which combine knowledge from entomological, epidemiological, simulation-based, and geo-spatial domains, are required for the identification of relationships between spatial variables, and may have important implications for malaria vector control. © 2013 DIME UNIVERSITAT DI GENOVA

Pengukuran Tingkat Kesiapan Kantor Pemerintahan Desa Dalam Penerapan Masterplan Teknologi Informasi Dan Komunikasi (Tik) Perkantoran Desa Menggunakan Kerangka Kerja Cobit 4.1

Desa sebagai bagian terkecil dari sistem pemerintahan administratif di Indonesia,dituntut untuk dapat mengikuti perkembangan teknologi dan terus meningkatkan kemampuannya didalam mengelola data administrasi kependudukan desa sebagaimana yang terkandung dalam amanat Inpres No. 3 tahun 2003. Saat ini desa-desa yang berada di Kalimantan selatan, didalam sistem pelayanan administrasi kependudukan desa masih banyak yang bersifat konvensional. Hal tersebut berimbas kepada perangkat desa maupun penduduk desa, dimana sering terjadi human error, serta pemborosan waktu dan biaya. Oleh karena itu dibutuhkan suatu sistem yang mengarah ke e-Government untuk mengatasi permasalahan-permasalahan yang ada. Dalam menerapkan e-Government dan tata kelola TIK di pedesaan diperlukan suatu perencanaan yang matang dan menyeluruh sehingga penerapan TIK bisa berjalan sesuai dengan fungsinya dan dapat membantu menyelesaikan permasalahan yang muncul pada saat telah diimplementasikan.
