AbstrakIndonesia adalah salah satu dari negara tropis dunia yang memiliki kekayaan biodiversitas yang sangat tinggi. Salah satu kawasan yang memiliki biodiversitas tinggi dan dijadikan cagar alam adalah Meru Betiri. Kawasan ini tidak hanya terkenal dengan perlindungan terhadap Harimau Jawa, tetapi juga berbagai keindahan panorama alam dan lokasi hutan hujan tropis yang masih terlindung, salah satunya adalah wilayah Bandealit. Penelitian ini bertujuan menentukan jalur strategis yang dapat disarankan sebagai jalur birdwatching di Bandealit. Pengamatan dilakukan selama dua hari, yaitu pada tanggal 16-17 Nopember 2012. Pengamatan dilakukan dengan menjelajahi jalur-jalur yang dinilai berpotensi sebagai lokasi pengembangan birdwatching. Selain itu, juga dilakukan wawancara terhadap orang-orang kunci untuk mengetahui fluktuasi jumlah spesies di kawasan, konfirmasi jenis, serta mencari informasi terkait spesies yang belum dapat ditemukan. Kami telah menentukan tiga jalur yang berpotensi sebagai jalur birdwatching, yaitu Muara Timur (jalur 1), Savana (jalur 2), dan Lintasan Satwa (jalur 3). Jalur 1 tidak direkomendasikan karena kuantitas dan kualitas spesies yang ditemukan tidak terlalu baik. Jalur 2 dan jalur 3 direkomendasikan untuk pengembangan wisata birdwatching di Bandealit.

This study aimed to determine the strategic path that can be recommended as a birdwatching path in
A spring is a place where water comes out of the ground seepage, seeps into the soil, then flows through cracks, gaps or natural tracts. Springs (sumber, tuk, umbulan, belik) are used to extract water by local people. This study was aimed at uncovering the knowledge about the types of sacred trees which supported the traditional conservation for water spring in Malang regency. The survey was carried out directly by taking three specimens in the spring environment. Interviews were conducted in person, in-depth, semi-structurally to the local community and tribe leaders. This study contained also the description of the diversity of sacred tree species which supported water spring in Malang Regency, East Java. The results of the study recorded 41 types of 27 genera and 20 families. The diversity of sacred tree species that are believed to be sacred include: ringin (Ficusbenyamina), lo (Ficusglomerata), serut (Streblusasper), ipik-ipik (Ficusprocera), ilat-ilat (Ficuscallosa), bendo (Artocarpuselastica), jambuklampokwatu (Syzygiumlittorale), aren (Arengapinnata), gayam (Inocarpusfagifer), cangkring (Erythrinafusca). The types of water spring supporter are: bambuori (Bambusablumeana), bambubetung (Dendrocalamusasper), bambuapus (Gigantochloaapus), and of the familiaApocynaceae (Ervatamiasphaerocarpa), kecrutan (Spathodeacampanulata), warugunung (Hibiscus similis) etc. The existence of those meaningful trees is a symbol of the existence of a spring and the start of sustainable culture and customs in Malang Raya. Thus, petrenneeds to get the recognition as a longer, traditional conservation model from the government especially from the local government in a form of village regulation. Preserving the springs and environment is a local wisdom of the people of Malang regency, in an effort to preserve traditional conservation and harmony with the lives of other organisms. Asian J.

The aim of this research was to evaluate the diversity of plant species along the tourist trails to Mt. Lamongan and combat any misconceptions about ecosystem restoration and the ecotourism development program in Mt. Lamongan. A floristic survey was done through flora identification along the hiking trail from the gate of Mt. Lamongan nature recreation area in Papringan Village to the slopes of Mt. Lamongan. The identified species were listed and their taxonomic status analyzed using information from the GRIN website. This study found that exotic plant species are abundant along the tourist tract. Human activities were identified as contributing to the introduction and establishment of exotic plant species. Result of the research indicate that restoration knowledge and techniques do not exist in the Mt. Lamongan region. A comprehensive evaluation of flora should be implemented to enhance the restoration program and protect forest area, especially the tourist corridor to the peak of Mt. Lamongan. Integrated actions to enhance restoration and promote tourism are needed. It encompasses strengthening the restoration concept and technology, eradication of exotic plant species, and establishing a proper tourism interpretive tract.To cite this article: Hakim, L., Rahardi, B. and Rachmansyah, A. 2018.

Relationship construction has a very important position in classification process for arranging taxonomy of organism. In the world of taxonomy, there are two the most familiar relationship diagram, cladogram and phenogram. In every construction activity, a researcher is always facing character state data from taxa that becomes components of the diagram. Calculation that is used for construction is often incorporate iterative or repetitive process that needs time and precision. The existence of calculating tools that produces both text and graphical output are hopefully decrease time and error during construction. Basic algorithm that is used in calculation is for phylogenetic construction by Kluge and Farris in 1969,for phenetic construction using cluster analysis with slight modification. Basic common algorithm used in the software is by calculating two dimensional arrays of taxa x characters matrix and creating distance or similarity matrix. In more detail the program creates one dimensional array of taxonomical object and each object has some other one dimensional array containing data commonly exist in a taxonomic unit. The relationship between one object and theother are regulated by an object that created by class representing taxonomic tree. Cladogram is constructed by calculating nearest distance between each taxon (OTU) and creating one HTU in every bifurcation. Phenogram is constructed agglomeratively by searching highest similarity between taxon then grouped into new taxon. Program calculates numerical data after we do character scoring. Final result for each user may be different; this may be due to decision by user during construction process. This paper hopefully attracts people from systematic computation to develop further into open source software and multi-platform feature.
ABSTRAKSeiring dengan perkembangan budaya, baik tradisional maupun modern (bioteknologi), penggunaan bahan pandan, dapat dijumpai di masyarakat, pasar tradisional, telah mengalami pergeseran karena digantikan oleh bahan lain, seperti tali oleh plastik, topi dari bahan kain. Kajian etnobotani dilakukan dengan pengumpulan secara "etnodirect sampling" yaitu teknik wawancara langsung maupun semi struktural. Metode yang dilakukan pada anatomi pandan meliputi: metode ekstraksi serat, pembuatan preparat melintang dan membujur daun, pengukuran panjang dan kekuatan serat daun dan pembuatan preparat melintang dan membujur akar tunjang. Tujuan jangka panjang penelitian ini adalah untuk mendapatkan database pandan (Pandanaceae) yang nantinya dapat digunakan untuk melakukan manejemen sumber daya pandan (Pandanaceae) guna pelestariannya di Jawa Timur, sehingga mendukung fungsinya secara ekologis dan dihasilkan juga pembudidayaan jenis pandan lainnya yang juga berpotensi. Adapun tujuan jangka pendeknya adalah untuk mendapatkan jenis pandan (Pandanaceae) yang bermanfaat untuk dikembangkan sebagai kerajinan yang nantinya dapat digunakan untuk meningkatkan taraf ekonomi masyarakat Jawa Timur melalui struktur anatomi. Ketiga jenis Pandan yaitu P. tectorus, P. labyrinthicus dan P. furcatus memiliki potensi untuk dikembangkan sebagai bahan dasar pembuatan tali tampar dan kerajinan. Potensi Pengrajin kerajinan berbasis tanaman serat masih dapat dikembangkan untuk mengembangkan kerajinan Pandan.
The growing of population of a pioneer species may show a unique behavior. Casuarina junghuhniana is reported as a pioneer species, this is because of its tolerance to adverse environment and transform it to become inhabitable for other organism. A comprehensive method involving field observation, the use of mathematical model and computation to understand plants behavior still needs to be developed. This paper is attempting to show a method to build a model for showing unique dispersal behavior of Casuarina junghuhniana. A relatively straightforward use of Fisher’s reaction diffusion equation, cellular automata based modeling and programming can show behavior easier to understand on a grid space. Some assumption must be used to represent the C. junghuhniana dispersal. As it is known that C. junghuhniana can reproduce both vegetatively and generatively, and both were assumed to have different dispersal behavior. Vegetative reproduction using shoots emerging from roots has pattern to spread close to each other. While generative reproduction by seeds which is lightweight has possibility spread further with the help of wind. The total model area of 1km 2 was divided into 300 × 300 cells which represents 1 km 2 area. Cellular automata apply the same rule to each cell and the result was observed from the pattern of cells interaction. A simple program was developed using Python with Jupyter Notebook an interactive computing environment. The number of iteration was limited before observed simulation reached one of area boundaries. The simulation running time was greatly reduced using Graphical Processing Unit (GPU) parallel processing. NUMBA was used as an interface between python and Compute Unified Device Architecture (CUDA), the GPU programming API. The simulation showed behavior of the trees spread downward along the slope. The wind direction simulation with additional data from wind rose available from internet was also demonstrated in the simulation. Modeling dispersal with influence from wind showed more sporadic pattern at further distance from originating parents cluster. The trees in the simulation showed clusters in dispersal pattern when rely more on generative reproduction. When the trees rely on vegetative reproduction by roots shoots, the population showed more like continuous cover. When concerning real 3 dimensional aspect, this simulation still can not distinguish vertical (z axis) aspect. It means two points would be seen as close to each other although they actually have far vertical distance. At this stage, the simulation has not yet been optimized to easily convert input from the wind rose. The wind information still needs to be written as code into the program.
Casuarina junghuhniana or mountain ru, she oak or cemara is a species from Indonesia which grows in the highland area at an altitude between 2000-3000 m above sea level (asl). One of the highland area in Eastern Java (Jawa Timur) of Indonesia is Bromo Tengger Semeru National Park (TNBTS). The study site was on the Tengger Sea of Sands, Eastern Java, Indonesia where it is affected by volcanic activity. This tree, from some references, has not been well studied yet although it has been reported as a tree native to Indonesia. The lack of the study poses problems when there is a program related to planting the tree on a certain location in TNBTS for rehabilitation purposes. This study attempted to construct a Structural Equation Model that mapped some factors observed in the study site related to C. junghuhniana population. Explored factors for their relationship with each other included the number of male and female individuals, growth-related indicators, and environmental factors consisting of altitude and the tree population. Formative factors which consist of parameters related to growth, environmental factors and factor associated with the diffusion of new individuals, may contribute to population growth while population growth was the opposite. The individual growth might not significantly contribute to the population of C. junghuhniana; instead, the population growth was affected by the tree individuals. Generative reproduction contributed the least to the dispersal as it may rely more on vegetative reproduction by adventitious shoots from roots.
