Judul: Perencanaan Interpretasi Berbasis Konservasi Bambu di Saung Angklung Udjo
Abstrak: Saung Angklung Udjo is one of the conservation of angklung where focused in West Java, It concerned to preserve the four types of bamboo (Black bamboo, Gombong bamboo, Temen bamboo, and Tali bamboo) which identified as angklung raw materials also to communicate information to visitors to get to know these resources. This study aims to develop a conservation plan based interpretation of bamboo as a raw material at Saung Angklung Udjo. The method was developed using qualitative descriptive methods to approach the interpretation of Sharpe is make objective, collection information, analysing, synthesis, plan, implementation, evaluation & revision, and feedback. Data were collected in the form of primary and secondary data including the type and characteristics of bamboo, bamboo processing into a musical instrument angklung, and conservation efforts that may involve visitors in Saung Angklung Udjo. Data were collected through observation, study of literature, and interviews with three informants and 50 respondents. The data obtained is used to make planning interpretation at Saung Angklung Udjo. There are four types of bamboo used as angklung raw materials namely black bamboo (Gigantochloa atroviolaceae), gombong bamboo (Gigantochloa pseudoarundinaceae), temen bamboo (Gigantochloa atter), and Tali bamboo (Gigantochloa apus). Fourth bamboo has physical properties and anatomy suitable as an angklung musical instrument. Procurement bamboo as angklung raw material was obtained by taking from nature and has not done the intensive cultivation. This condition affects the existence of four types of bamboo are increasingly rare. Conservation bamboo species as angklung raw material needs to be done in order to maintain the existence and type of angklung art. Business partners and farmer (harvesters) have bamboo conservation efforts. One effort can to do Saung Angklung Udjo managers through the delivery of information related to the type and characteristics of bamboo, bamboo processing effort into conservation efforts bamboo to the visitor. Forms of interpretation that was developed in the form of plans and programs based interpretation facilities conservation angklung bamboo as raw material. Program and interpretation boards are developed to enhance the appreciation of visitors directed to the conservation of bamboo as angklung raw material.

Judul: Ekologi dan Bioprospeksi Bambu di Kawasan Taman Wisata Alam Gunung Baung Pasuruan Jawa Timur
Abstrak: Bamboo is one of plant taxa comprising various species with high economic potential. Bamboo is a member of Bambusoideae of the Poaceae family. There are 1250 bamboo species in the world, 135 of them are in Indonesia. Not all bamboo species are well known, and only some of them can be found in Java Island. Land use changes reduce bamboo natural habitats in Indonesia. One of the bamboo forests in East Java is found at a conservation area namely Mount Baung Natural Park. The information of bamboo diversity, population structure and the relationship between bamboo and its biotic and abiotic factors in Mount Baung Natural Park is not well known. The aims of the research were to study the ecology of bamboo, the relationship between bamboo growth and its biotic and abiotic factors, and the bio-prospection aspect of this taxon in Mount Baung Natural Park, Pasuruan, East Java. This research was carried out at four different locations from September 2011 to Mei 2012. Those locations were Preserved Area, Rehabilitation Area, Limited Usage Area, and Intensive Usage Area. Data collection was conducted by analyzing the bamboo populations using sampled plots along the transects that were determined by stratified random samplings within four purposive sampled areas. The collected botanical data consisted of the bamboo scientific names, the number of clumps per plot and the diameter of clumps. The environmental data consisted of altitude, solar radiation, temperature-humidity, and soil pH. Soil samples were analyzed at the Soil Chemical Laboratory, Center for Research of Land Resources, Bogor. The abundances and densities of bamboo expressed an importance value index, namely the resultant of the sum of Relative Density, Relative Frequency, and Relative Dominance. The determination of habitat characteristics (i.e. determining the most related factors in relation to the presence of bamboo in their community) were analyzed by statistical correlations using the software STATISTICA Minitab 14. The principal component analysis (PCA) and cluster analysis were performed to determine relationships between abiotic/biotic components and bamboo’s occurrences. Canonical Correspondence Analysis (CCA) was used to determine component relationships. Cluster analysis was used to analyze the similarity of the environmental conditions of the bamboo habitat. Index Cultural Significance (ICS) was performed to determine the bamboo bio-prospecting of bamboo. There were seven species of bamboo in Mount Baung Natural Park, Pasuruan, namely Bambusa blumeana, Bambusa vulgaris, Dendrocalamus asper, Schizostachyum iraten, Gigantochloa apus, Gigantochloa atter and Dinochloa matmat. D. matmat was not described detail in this These due to the very limited number ( < 1%) of individual occurence. Among the six bamboo species, B. blumeana possessed nearly ideal population structure. Bambusa blumeana had the highest important value index 127,97%. The structure of bamboo population was classified based on the clump diameter classes which were: A (< 5 m), B (5-10 m) and C (> 10 m). Based on this category, the bamboo in Mount Baung Natural Park belonged to A phase class. Based on the soil analysis, the location had good soil characteristics and was feasible for bamboo growth, namely silty clay loam, medium CEC (Cation Exchange Capacity) ranging from 10,90 to 18,52

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
