Community Structure of Phytoplankton in Sekotong and Kodek Bay Waters, West Lombok

Phytoplankton plays important roles of food weeb in aquatic ecosystem, can absorb and release CO2 which is very useful for other organisms and the environment. The purpose of this research was to study the community structure, including abundance, composition and diversity of phytoplankton in the Sekotong and Kodek Bay, West Lombok. The study was conducted in April 2012 at 10 stations in the Sekotong Bay and six stations in Kodek Bay. Sampling was done vertically by using plankton Kitahara net having mesh size of 80 μm. The results showed that the abundance of phytoplankton from 10 stations in Sekotong Bay ranged between 834,134-6,488,888 sel/m3, while in Code Bay ranged between 53,571-191,642 sel/m3. Phytoplankton dominant in the waters of Sekotong Bay were Chaetoceros and Skeletonema, while in Kodek Bay the dominant phytoplankton were Chaetoceros, Hemialus, Lauderia, and Skeletonema. The results of the analysis of the diversity of phytoplankton genera in Sekotong Bay showed the value of diversity index (H')=0.40-1.13 and dominancy index=0.41-0.85. While in Kode Bay, the diversity of phytoplankton genera showed the value of diversity index (H')=1.53-1.98 and dominancy index=0.03-0.28. Based on these results, it can be concluded that the diversity of phytoplankton genera in the waters Sekotong Bay could be classified as less to moderate and there was a tendency of being dominated by one genera in the population. The diversity of phytoplankton genera in Kodek could be classified as moderate and there were low tendency of domination by certain genera in the population

Kajian Faktor-Faktor Penyebab Anak Putus Sekolah di Desa Jangrana Kecamatan Kesugihan Kabupaten Cilacap

The purpose of this study to determine the factors - causes of children drop out of school in the Village DistrictJugrana Kesugihan Cilacap. This survey study took the population of children who have dropped out ofelementary education level is 9 years compulsory education as much as 22 respondents. The sample is taken byusing total sampling technique that is taken as a whole from the number of respondents that is 22 respondents.Technique of collecting data using questionnaire. Data processing is done by using frequency table andanalyzed by descriptive qualitative. The result of the research shows that children drop out of school inJangrana Village Kesugihan subdistrict of Cilacap Regency because of family environment factor that is theamount of children that become the dependent of parents, school environment factor that is often experiencingconflict with fellow friend in school, environmental factor of society because society where he lives the majorityof poorly educated, economic factors in the form of a lack of provision of parental gear and learning tools andinterest factors because children choose to work instead of going to school. The most dominant factor causingthe drop out of school in Jangrana Village Kesugihan Subdistrict of Cilacap Regency is interest facto

Vegetation Composition of Savanna Ecosystem as a Habitat For The Komodo Dragon (Varanus komodoensis) on Padar and Komodo Islands, Flores East Nusa Tenggara Indonesia

Tropical savanna and dry forest in Indonesia are an important type of ecosystem that supports various endemic wildlife of Indonesia including savannas at Padar and Komodo Islands which is home to the Komodo (Varanus komodoensis). The Komodo dragon is considered as “Vulnerable” by the International Union for Conservation of Nature. Studies with regards to the Komodo dragons’ habitats are scarce, considering that these types of habitats are significant to support Komodo’s existence, but yet are also very prone to conversion and disturbances. This paper elaborates the results of ecological study on the tropical savanna forest in Komodo National Park as habitat for the Komodo dragon. Vegetation sampling was conducted using nested plots 20 x 20 m, 10 x 10 m, 5 x 5 m and 2 x 2 m spread across the sampling sites. Data was analysed using PRIMER software which includes cluster analysis, analysis of similarity (ANOSIM) and similarity percentage (SIMPER). As many as 17 plant species which belongs to 11 families were identified in the sampling sites. These consist of six trees habitus, six shrubs, four grasses and one palm. Asteraceae, Fabaceae and Poaceae were the plant families which has high number of species. The result of cluster analysis shows that the similarity level of the two groups (Komodo and Padar) based on the results of cluster analysis is 60%. This result infers that there are similarities in terms of species composition in savanna on Komodo and Padar Island, however, each savanna still has its own species characteristics. This is confirmed by the ANOSIM test. The ANOSIM test results show the Global R value of 0.6.With the looming challenges from invasive alien plant species (IAPS), the Komodo Island’s savanna has double threats to overcome. Hence conservation of the remaining savanna ecosystem is importan
