Status Persentase Tutupan Karang Scleractinia Di Pulau Bunaken (Taman Nasional Bunaken) Dan Di Pantai Malalayang, Pesisir Kota Manado

Karang scleractinia atau karang batu merupakan karang pembentuk terumbu. Sehingga penentuan status kondisi karang batu menjadi bagian penting dan sangat menentukan peran ekologis dan ekonomis ekosistim terumbu karang. Salah satu parameter untuk mengetahui kondisi karang batu yaitu persentase tutupan di alam. Penelitian dilakukan menggunakan metode deskriptif kuantitatif dengan tehnik pengambilan data dengan menggunakan LIT (Line InterceptTransect) yang selanjutnya dianalisis dengan Persentase Tutupan Karang setelah data diolah dengan ‘benthic life form\u27. Parameter lingkungan berupa salinitas dan suhu air serta kecerahan juga diukur.Hasil penelitian menunjukkan bahwa persentase tutupan di perairan pantai Malalayang Kota Manado dalam status kategori ‘poor\u27 (Buruk) khususnya di kedalaman 3 dan 5 meter yaitu pada kisaran antara 0-24,9 %, sekalipun pada kedalaman 10 meter hanya kategori ‘good\u27 (Baik), pada kisaran antara 50 – 69,9 %.. Sedangkan di stasiun penelitian Pulau Bunaken baik di bagian selatan yaitu Stasiun Fukui dan bagian utara pulau yaitu Stasiun Pangalisang hasilnya sebagian besar ‘excellent\u27 (sangat baik) yaitu dalam kisaran > 70 % persentase tutupan karang batunya. Dengan demikian diketahui bahwa karang yang berada di kawasan yang dilindungi atau konservasi masih relatif lebih baik kondisinya daripada karang yang berada di kawasan terbuka untuk umum sehingga tekanan kegiatanantropogenik intensitasnya relatif tinggi

Information géographique numérique et gestion des territoires. Application aux zones côtières françaises

International audienceLe développement des Technologies de l’Information Géographique entraîne la multiplication des ressources informationnelles géolocalisées et de leurs échanges via le Web. A travers une analyse complémentaire menée à l’échelle nationale et locale, cette communication propose d’analyser la contribution de ces ressources informationnelles aux processus de gestion territoriale en zone côtière. Des décalages sont mis en évidence entre les potentialités offertes par ces ressources informationnelles et leurs effets réels sur l’aide à la gestion territoriale en dépit de la mise en oeuvre de politiques publiques en faveur du numérique

Seagrass Community of the Coastal in Southern of Bangka Island, North Minahasa Regancy, North Sulawesi Province

Purpose of this research is to know the community of seagrass, and physical-chemical parameters in the South Bangka island, North Minahasa Regancy, North Sulawesi Province. Data retrieval by the random sampling of systematic method on three lines transect with 50 m long, and 30 quadrants. Data taken in each quadrant is number of species and number of individuals of each species. Results of the measurement of physical and chemical parameters of static waters associated with the feasibility of life for water organisms in it, generally in good condition. Ten species of seagrass have been found in the southern part of the island of Bangka. Four species are always found in any transek i.e Syringodium isoetifolium, Cymodocea rotundata, Enhallus acaroides, and Halophylla ovalis. The highest found in seagrass cover transek 1 i.e. 67.00% while the lowest in transek 3 i.e. 46.30%. Seagrass cover Enhallus acaroides in Bangka island very prominent compared to other species. Based on the current index value is important, Syringodium isoetifolium have a high importance value index only in the transek 3 which means this type of seagrass seagrass types affect other takes part in community level. Ecological index results suggest that the ecosystem of seagrass in Bangka island in the southern part of the State is stable

Site-directed mutagenesis of conserved inverted repeat sequences in the xylanase C promoter region from Streptomyces sp EC3

Streptomyces sp. EC3, a strain which was originally isolated from cattle manure compost, was shown to possess a strong xylanolytic activity. One of the genes responsible for this activity, xlnC, encodes a secreted xylanase. In the native strain, as in the heterologous host S. lividans, expression of xlnC was detectable in the presence of xylan but not in the presence of glucose. Induction by xylan was shown to take place at the transcriptional level. The transcriptional start site of xlnC was mapped and likely -35 (5'-TTGACA-3') and -10 (5'-GAGAAC-3') motifs were identified. In order to localise putative conserved regulatory sequences, the promoter regions of xylanase-encoding genes from various Streptomyces species were aligned. This alignment revealed the existence of three sets of quite well conserved palindromic AT rich sequences called boxes 1, 2 and 3. Box 3 (5'-CGAAA N TTTCG-3') is the farthest away from the promoter region (150-200 bp). A shorter version of this palindrome (5'-GAAA NN TTTC-3') or (5'-CGAAA-3') constitutes box 1, which is located just upstream of the putative -35 promoter sequence. Box 2, located 5-7 bp upstream of box 1, comprises a shorter palindrome than box 3, with inverted polarity [5'-(G/C)TTTC (N) GAAA(G/C)-3']. The putative regulatory role of the conserved inverted repeats in boxes 2 and 3 in the promoter region of the xlnC gene from Streptomyces sp. EC3, was assessed. These boxes were modified by site-directed mutagenesis, and the mutant promoter regions, as well as the wild-type promoter region, were separately fused to a beta-lactamase reporter gene. Analysis of the expression patterns of these fusions in cultures grown in the presence of glucose, xylan or both carbon sources demonstrated that these motifs were cis -acting negative regulatory elements, each playing a specific role in the regulation of xlnC expression. Box 3 was shown to be critical for the establishment of repression of xlnC expression by glucose, whereas box 2 was shown to play an important role in the induction of xlnC expression by xylan.Peer reviewe

Implementation of Environmentally Friendly Monitoring Method: "Green Watch" and "Image Analysis" in Sustainable Resource Utilization in the Coast Community of the Gulf of Amurang, North Sulawesi

Monitoring the condition of coral reefs using 'green watch' and 'image analysis' in the use of sustainable resource in the coastal communities of the Gulf of Amurang North Sulawesi has been conducted with the purpose of (1) to understand the condition of coral reefs in the waters of TEEP and Kapitu, (2) the coastal communities can utilize the method of 'green watch' and 'image analysis', and also can do the monitoring themselves both groups and individuals. Results of research by two methods illustrates that there are seven types of coral growth in the waters of Teep, and 8 types in the waters Kapitu village, where each type of coral growth showed different in percent cover. Overall reef condition for waters in the village of TEEP is very good with 79% of live coral, while the  Kapitu village is good with a percentage of live coral is 64%. With this condition is expected that the community can do the monitoring continuously, and also rehabilitate the damage corals. By doing so the resources will be always available for both village.   Keywords: Coral Reef, associate organisms, 'green watch', 'image analysis', live coral  and dead coral, percent cover, Abstrak Monitoring kondisi terumbu karang dengan menggunakan metode ‘green watch’ dan ‘ image analysis’ dalam pemanfaatan sumberdaya yang berkelanjutan di komunitas pesisir Teluk Amurang Sulawesi Utara telah dilakukan dengan tujuan (1) memahami kondisi terumbu karang di perairan Teep dan Kapitu, (2) masyarakat nelayan dapat memanfaatkan metode ‘green watch’ dan ‘image analysis’, sekaligus melakukan monitoring secara mandiri baik kelompok maupun individu.  Hasil penelitian dengan dua metode ini menggambarkan bahwa ada 7 tipe pertumbuhan karang di desa Teep, dan 8 tipe di perairan desa Kapitu, di mana masing masing tipe pertumbuhan karang hadir dengan presentase tutupan yang berbeda.  Kondisi karang secara keseluruhan untuk perairan di Desa Teep adalah yang sangat bagus dengan 79 % karang hidup, sedang untuk desa Kapitu adalah cukup bagus dengan presentase karang hidup adalah 64 %.  Dengan kondisi ini diharapkan masyarakat dapat mempertahankan, dengan cara melakukan kegiatan monitoring secara berkesinambungan, sekaligus merehabilitasi kondisi karang yang telah rusak. Dengan  mempertahankan kondisi yang baik ini maka servis dari ekosistem ini terhadap masyarakat di kedua Desa ini akan terus ada.   Kata kunci: Terumbu Karang, organisme asosiasi, ‘green watch’, ‘image analysis’, karang hidup, karang mati, persentase tutupan

THE INDIVIDUAL REIMAGINED: INVESTIGATING RESPONSIBILITY THROUGH DEWEY AND A FEMINIST ETHICS OF CARE

56 pagesContemporary social and political spaces often engage questions of freedom, ranging from abstract musing on free will and causality to significant political debates about the relationship between individuals and the state. However, seldom do these debates go to the fundamental problem at hand, namely, what defines the relationship between the individual and liberty? This thesis will explore how this fundamental relationship has been engaged in order to come to a morally robust understanding of our position as individuals in the world. This paper argues—in contrast to many current understandings—that the individual is not a primary ontological status, but rather develops out of natural interdependences that shape our organic relationship with various environments; by demonstrating this point, it will become clear that questions of liberty must be oriented towards addressing our engagement and responsibilities in an interdependent world. This paper develops this problem by engaging the work of John Dewey—specifically his grasping of ontology and resulting moral framework—as well as the field of feminist care ethics. By offering a synthesis of these two fields, what is developed is a self-reflecting ethical framework that is principled on the natural interdependencies of human ontology and is therefore prepared to wholly engage how responsibility relates to us as engaged individuals
