Integrasi Citra Alos Avnir-2 Dalam Sistem Informasi Geografi Untuk Mengidentifikasi Kesesuaian Penggunaan Lahan Di Sebagian Kabupaten Cilacap
Wilayah pesisir mempunyai potensi sumber daya alam yang tinggi. Pesisir merupakan tempat yang strategis untuk permukiman, tambak, sawah, pariwisata dan kebudayaan. Namun, banyak faktor yang menyebabkan pembangunan di daerah ini perlu diperhatikan. Pemanfaatan lahan pesisir harus disesuaikan dengan kondisi optimal, berdasarkan syarat penggunaan lahan. Penelitian ini bertujuan untuk mengidentifikasi potensi lahan dan mengidentifikasi kesesuaian penggunaan lahan di sebagian pesisir Kabupaten Cilacap. Data ALOS AVNIR-2 digunakan sebagai referensi untuk interpretasi parameter evaluasi penggunaan lahan. Analisis menggunakan sistem informasi geografi (SIG) mendukung perbandingan antara persyaratan dan kondisi satuan medan. Berdasarkan hasil subjective matching, lahan potensial yang sesuai untuk pertanian, permukiman dan tambak adalah 80,08 persen. Perbandingan antara potensi lahan dan penggunaan lahan aktual mendapati hasil kesesuaian penggunaan lahan 78,47 persen sesuai untuk permukiman, 66,75 persen sesuai untuk pertanian dan 56,94 persen sesuai untuk tambak

The aim of this research was to know the condition of african catfishbreeding in tarpaulin pool at hangtuah village and the development possibilities inthe future discussed on the financial side, and also to know the proper level ofAfrican catfish breeding effort at hangtuah village.The applied method in this research was survey method. Respondents inthis research is farmers who do breeding the African catfish in tarpaulin pool athangtuah village, where the populations is 330 people and the number ofrespondents who where taken as much as 5% of the total populations of thefarmers as many as 16 respondents. Taking as much as 5% of respondents dobecause the majority of populations at hangtuah village have the same job(homogen).The average of stated financial used by the farmers at hangtuah villagewas Rp. 4.239.375,00 per month. The average of total cost used was Rp.2.450.895,00 per month. The profit range got by the farmers was Rp.1.788.479,6,00 per month. BCR values were 1,84 for this fish breeding. It meantthat this breeding effort deserve to be continued cause the BCR values >1,meanwhile the PPC values range at 5,02

Pembuatan Tata Kelola Keamanan Informasi Kontrol Akses Berbasis ISO/IEC 27001:2005 Pada Kantor Pelayanan Perbendaharaan Surabaya I
Perkembangan teknologi informasi yang pesat saat ini turut berimbas kepada penggunaan teknologi informasi di lingkungan pemerintahan. KPPN Surabaya I sebagai instansi vertikal dari Direktorat Jenderal Perbendaharaan juga menerapkan teknologi informasi dalam untuk mendukung kegiatan pelayanan terhadap satuan kerja yang berada di lingkup bayarnya. Sayangnya masalah keamanan informasi yang merupakan bagian penting dari teknologi informasi sering kali kurang mendapatkan perhatian. Tidak dapat dipungkiri bahwa munculnya ancaman ataupun kelemahan dalam teknologi informasi dapat menggangu jalannya kegiatan pelayanan yang menggunakan teknologi informasi. Oleh karena itu diperlukan pengelolaan teknologi informasi berbasis risiko yang dituangkan dalam tata kelola untuk mengelola ancaman ataupun kelemahan yang muncul. ISO/IEC 27001:2005 merupakan framework sistem manajemen keamanan informasi yang dapat dijadikan dasar dalam pengelolaan keamanan informasi. Tata kelola keamanan informasi yang dibuat ini menitikberatkan pada kontrol akses yang merupakan salah satu kotrol keamanan dari ISO/IEC 27001:200
Karakteristik Morfologi dan Habitat Ikan Brek (Barbonymus Balleroides Val. 1842) di Sungai Serayu Jawa Tengah
Brek is a consumption fish belong to barbs group that widely distributed, one of them is in Serayu river. The aims of this study was to reveal the characteristics of meristic, morphometric, and habitat of the species. The study was conducted on the Serayu river especially in Banjarnegara, Central Java Province. Sampling was conducted on May 2012 to June 2013. The area of study was divided into three zones and the zones was categorized based on Reservoirs at Mrica area these are upper zone, reservoir zone, and below the reservoir zone. Fishing gear used are cast net, elektorfishing, and gill nets. Samples of fish were caught preserved in 4-10% formalin solution and then observed in the laboratory. Morphometric characters observed were 24 characters. The results were standardized to standard length, then analyzed with discriminant methods. The structure of the scales and number of ridges on the back of the last dorsal fin spines also observed. The results meristic characters are 4.8 dorsal fin, 3.5 anal fin, 1.14-16 pectoral fin, and predorsal 10-13 scales, also there were no spots on the caudal peduncle. The results of discriminant analysis showed known five characters distinguishing three species near 100%. The habitats have rocky bottom, rapid current, and divide into two groups
Pola Pertumbuhan Dan Nisbah Kelamin Ikan Brek (Barbonymus Balleroides Vall. 1842) Pada Habitat Yang Terfragmentasi Di Sungai Serayu Jawa Tengah
A total of 2466 fish were sampled from Serayu River in Banjarnegara, Central Java. The aims of study are to assessthe relationships among length weight, growth, condition factors and sex ratio of of the brek fish (Barbonymusballeroides) with fragmented habitat. The study started from June 2012 to May 2013 using survey mehods. Thestudy sites consist of six stations which were into three segments based on the reservoir position, i.e lower segment(St.1-St.2), middle segment (St.3-St.4), and upper segment (St.5-St.6). The results show length weight relationshipwere W= W= 7.10 -7*L3.084 (r2= 0.97) for all specimens, W = 8.10-6 *L3.061 (r2= 0.96) for males, and W= 7.10-7*L3.089(r2= 0.98) for females; growth pattern were allometric over all condition factor were almost the both males andfemales, i.e. 1.0234 and 1.0275 respectively. Based on the segment, males were the highest in March at the middlesegment i.e 1.2105 (n= 49) and the lowest at was the upper segment i.e. 0.8952 (n = 29). In females, the highestwas also in March at the upper i.e. 1.1895 (n = 19) and the lowest in April at the lower segment i.e. 0.9478 (n=35); sex ratio consists of 1073 males and 1393 females or 1: 1.29

Longitudinal analysis of T-cell receptor repertoires reveals persistence of antigen-driven CD4+ and CD8+ T-cell clusters in systemic sclerosis
The T-cell receptor (TCR) is a highly polymorphic surface receptor that allows T-cells to recognize antigenic peptides presented on the major histocompatibility complex (MHC). Changes in the TCR repertoire have been observed in several autoimmune conditions, and these changes are suggested to predispose autoimmunity. Multiple lines of evidence have implied an important role for T-cells in the pathogenesis of Systemic Sclerosis (SSc), a complex autoimmune disease. One of the major questions regarding the roles of T-cells is whether expansion and activation of T-cells observed in the diseases pathogenesis is antigen driven. To investigate the temporal TCR repertoire dynamics in SSc, we performed high-throughput sequencing of CD4+ and CD8+ TCRβ chains on longitudinal samples obtained from four SSc patients collected over a minimum of two years. Repertoire overlap analysis revealed that samples taken from the same individual over time shared a high number of TCRβ sequences, indicating a clear temporal persistence of the TCRβ repertoire in CD4+ as well as CD8+ T-cells. Moreover, the TCRβs that were found with a high frequency at one time point were also found with a high frequency at the other time points (even after almost four years), showing that frequencies of dominant TCRβs are largely consistent over time. We also show that TCRβ generation probability and observed TCR frequency are not related in SSc samples, showing that clonal expansion and persistence of TCRβs is caused by antigenic selection rather than convergent recombination. Moreover, we demonstrate that TCRβ diversity is lower in CD4+ and CD8+ T-cells from SSc patients compared with memory T-cells from healthy individuals, as SSc TCRβ repertoires are largely dominated by clonally expanded persistent TCRβ sequences. Lastly, using “Grouping of Lymphocyte Interactions by Paratope Hotspots” (GLIPH2), we identify clusters of TCRβ sequences with homologous sequences that potentially recognize the same antigens and contain TCRβs that are persist in SSc patients. In conclusion, our results show that CD4+ and CD8+ T-cells are highly persistent in SSc patients over time, and this persistence is likely a result from antigenic selection. Moreover, persistent TCRs form high similarity clusters with other (non-)persistent sequences that potentially recognize the same epitopes. These data provide evidence for an antigen driven expansion of CD4+/CD8+ T-cells in SSc
