EKOLOGI BENTANG ALAM DUSUN MALEMPO, RESORT MALLAWA TAMAN NASIONAL BANTIMURUNG BULUSARAUNG, KABUPATEN MAROS PROVINSI SULAWESI SELATAN

ABSTRACT This study aims to identify the elements of the landscape and its relation to ecology contained in the Malempo Village, Mallawa Resort, Bantimurung Bulusaraung National Park. Data was obtained by, observing the landscape, and other data through information from interview with the Special Police of Bantimurung Bulusaraung National Park, as well as from the surrounding community. The data were then grouped into constituent elements of the landscape. Ecological analysis was done by reviewing the constituent elements of the landscape, in this case the matrix, patches, and corridors, and then evaluating them based on the condition of the structure, function and dynamics of the ecological, as well as a variety of bio-physical conditions-social-economic-cultural and related to conditions bio-climatic zone that took place in the research area. Understanding the character of the landscape is done with photograph shooting. The matrix elements of the landscape is a mountain Malempo Village. Patch found in the form of housing, fields, gardens, forests, land that is not cultivated, vacant land with herbaceous plant grass, vacant land without crops, half-empty land, vegetation trees distributed between the fields; banana plantation and herbaceous shrub vegetation on the edge of rice fields; and forest between the mountains and the matrix patch banana plantation and chili. Patches that are subjected to very high intensity of human beings is, rice terracing system, cornfield on steep land, orchards mixture of peanuts and bananas (Musa paradisiaca), with vacant land and house in the garden. Corridor in the study site in the form of waterways, walkways special, and public roads. Keyword: Corridor, Matrix, Patch, Landcsape, Mallawa Resort, Malempo Villag

Ekologi Lansekap Kawasan Taman Nasional Gunung Gede Pangrango Resot Area Bedogol

 Understanding of landscape dynamics provide profound implications on the management and landscape planning. Mount Gede Pangrango National Park  (MGPNP) has a nature which is  unique and spesific, which made this national park as one of the laboratory  for landscape ecology research. The research objectives were to observe and identified the structure, function, and dynamic of MGPNP’s landscape, particularly at Bedogol resort. The landscape’s mosaic, patch, and corridor were studied and analyzed based on ecological structure, dynamic, and function conditions, and also with various bio-physic social economic and culture which related to bioclimatic zone condition. Landscape mosaic of MGPNP was composed of various ecosystem started from spesific ecosystem of lowland tropical rain forest to the mountain forest. The identifying patch were forest, resting house, gazebo, small field, house and seedbed for protected plant and medicinal plant. The landscape corridor’s were street and pathway. There were two kind of corridor forms, which were line and hedgerow corridor

Pythososiologi Tumbuhan Bawah di Desa Tabo-Tabo, Kabupaten Pangkep, Sulawesi Selatan

Penelitian ini adalah penelitian deskriptif yang dilakukan untuk menentukan kondisi struktur dan komposisi vegetasi di wilayah tersebut. Data diperoleh melalui metode quadrat dengan menggunakan sebanyak 100 buah kuadrat ukuran 2x2 meter. Spesies anakan pohon dan semak yang ditemukan di area tersebut adalah: M. Invisa; A. crassicarpa; S. rhombifolia, M. pudica, L. cernuum, and L. scandens. Spesies herba yang ditemukan antara lain C. esculentus, C. rotundus, C. brevifolius, C. aeriginosum, G. divaricata, and I. cylindrica. Vegetasi semak dan anakan pohon mempunyai  range Indeks  Keanekaragaman Shannon Wienner dari 1.36 sampai  1.38, 0.26 sampai  03.5 untuk Indeks Kekayaan dan Indeks Kemerataan dari 0.33 sampai 0.43. Vegetasi Herba mempunyai range Indeks Keanekaragaman Shannon Wienner diversity 1.36 sampai 1.38, 0.26 sampai 0.35 untuk Indeks Kekayaan dan Indeks Kemertaan mempunyai range dari 0.33 sampai 0.43

Kawasan Tropis Pegunungan sebagai Kawasan Rawan Bencana dengan Nilai Ekologi Tinggi dan Upaya Pelestariannya

Kawasan tropis pegunungan (KTP) merupakan kawasan yang rentan atau rawan bencana, baik secara alami maupun antropogenik. Pemahaman terhadap konsekuensi perubahan habitat, dan usaha pengembangkan strategi efektif untuk mempertahankan proses-proses ekologi pada KTP merupakan tantangan bagi ilmuwan dan praktisi koservasi alam.  KTP penting dalam proses siklus hidrologi, pengaturan kelembaban udara regional, pengurangan erosi dan sedimentasi, juga menyediakan sumberdaya penting baik kayu maupun non kayu. Ancaman terhadap KTP diantaranya adalah pembukaan lahan, eksplotasi sumberdaya alam yang berlebihan, jumlah penduduk yang semakin meningkat dan gempa bumi serta letusan gunung merapi. Pengelolaan KTP menuntut komunikasi dan kerjasama efektif antar stakeholder dan memastikan proses-proses ekologi kawasan pegunungan dapat terus berlangsung melalui pemanfaatan sumberdaya alam KTP yang berkelanjutan

Penentuan Struktur Vegetasi Tumbuhan Herba dengan Menggunakan Program R

Pemrograman dengan menggunakan bahasa R untuk penentuan struktur vegetasi telah dapat dibuat. Struktur vegetasi yang ditentukan adalah kelas penutupan tajuk Braun Blanquet, Indeks Nilai Penting Spesies, Indeks Keanekaragaman Shanon Wiener, Indeks Simpson, Indeks Keanekargaman Simpson, Indeks Reciprocal Simpson, Indeks Kemerataan, dan Indeks Kekayaan

The Research Objective Was to Study Tree's Vegetation Structure Based on Diameter Class Distribution on Varians Vegetation Types at Salak Mountain. Samples Were Taken at North, South, East, and West Facing Slope of Salak Mountain Using Line Transect. Systematic Sampling with Random Start Was Used to Locate the Transetcs. Measuring Stem Diameter at Breast Height Was Done in Order to Study the Tree Diameter Class Distribution. Non Parametric U Man Whitney Statistic Was Used to Know Whether There Was a Different in Number of Individual at All Diameter Class in Each Vegetation Type. at Mix Forest and Plantation Forest, the Tree Diameter Class Distribution Forming J Curve Shape. at Bamboo Forest, the Individual Number Increase at the Highest Class Diameter. the Number of Individual Trees Were Highest at Mix Forest and Lowest at Bamboo Forest. Key Words: Mount Salak, Reverse J Curve, Tree Diameter Class, Vegetation Type
