Ecological Show Cave and Wild Cave: Negative Binomial Gllvm’s Arthropod Community Modelling
Abstract Ecology is a branch of biology that studies the interaction and relationship between organisms and their environment. Abundance, distribution of organisms and patterns of biodiversity are great interests for many ecologists. One of interesting ecosystems to be studied is a cave. A cave has a typical environment character withRead More
Short Communication: Cave-dwelling Arthropod community of Semedi Show Cave in Gunungsewu Karst Area, Pacitan, East Java, Indonesia
ABSTRACT.Arthropods are a major group of animals which have significant roles in maintaining cave ecosystem stability. Semedi is a new show cave, but information about arthropods in this cave was not available. The use of cave as a tourist attraction will bring environmental changes which potentially disturb cave-dwelling arthropod community.Read More
The difference on Arthropod communities’ structure within show caves and wild caves in Gunungsewu karst area, Indonesia
ABSTRACT. This study was conducted to determine the differences on Arthropod communities’ structure and climatic-edaphic factors within wild caves and show caves in Gunungsewu karst area, also analyze the climatic and edaphic components that give the strongest influence on Arthropods community. Arthropod Sampling was done by hand collecting, pitfall and baitRead More
Statistics Ecology and Biodiversity
GOALS : We conducted research about Statistics Ecology and Biodiversity in collaboration with the Indonesian Speleological Society (ISS) and the Indonesian Institute of Sciences (LIPI, Indonesia). The significance of this research is to calculate an index of species, richness, diversity, evenness, and dissimilarity. Also, Analyze the climatic and edaphic factor components thatRead More
[SYNTAX R ] DISTRIBUSI NORMAL MULTIVARIAT
Analisis Multivariat merupakan salah satu metode dalam analisis statistik yang banyak digunakan dalam penelitian kuantitatif yang melibatkan banyak variabel. Ada beberapa metode dalam Analisis Multivariat, antara lain Analisis Faktor, Analisis Diskriminan, Analisis Klaster, Multidimensional Scaling, Analisis Konjoin, dan Model Persamaan Struktural (SEM). Secara lengkap teori yang berkaitan dengan analisis multivariat dapat dilihat padaRead More
[SYNTAX R] UJI KECOCOKAN DISTRIBUSI PELUANG
Permasalahan : Membangkitkan 50 data random dari distribusi peluang binomial, chisquare, gamma, dan F . Dengan distribusi tersebut kita dapat membangkitkan 50 bilangan random akan tetapi khusus untuk distribusi binomial hasilnya adalah bilangan bulat karena distribusi tersebut adalah diskrit. Distribusi yang lain adalah kontinu sehingga hasil bilangan randomnya adalahRead More
