Floristic Composition, Distribution, and Association of Pandanus (Pandanaceae) in Bukit Duabelas National Park Jambi

Pandanus species is widely distributed over Bukit Duabelas National Park in Jambi. Suku Anak Dalam (SAD), a local community living in Bukit Duabelas National Park area, use the natural fibers from Pandanus for many necessities, such as plaiting, building materials, and performing mytological rituals. This study aimed to examine floristic composition, distribution patterns, and association of pandanus species in Bukit Duabelas National Park. Sampling was conducted using a striped line, with a plot of 35 sample plots. Dominance of species was calculated using dominant type of important Value Index (IVI) based on the density, frequency, and dominance of sample plot enumeration. Distribution patterns was analyzed using the Morisita Index, while association patterns were measured by Contingency tables and Chi-square tests. Floristic composition was mostly found in the seedling strata consisting of 106 species. The species with highest important value index (IVI=14.53) was Palaquium gutta. There were two species of Pandanus (Benstonea kurzii and Benstonea atrocarpa) were spread in groups and three species of pandanus (Pandanus labyrinthicus, Pandanus furcatus, and Pandanus immersus) were spread evenly. The pandanus species found was associated with Benstonea kurzii was Litsea sp1. This present study suggested that the conservation of pandanus species should be conducted as a piece of rehabilitation of tropical forests in Bukit Duabelas National Park

Diversity of Amphibians (Order Anura) in Cibodas Resort Tourism Route, Gunung Gede Pangrango National Park

Cibodas Resort is one of the protected areas in Gunung Gede Pangrango National Park which is capable of supporting amphibian life. Amphibians can be used as bioindicators of environmental quality, especially aquatic ones. Amphibian studies are found to be interesting, but publications on amphibian data, especially at Resort Cibodas, are still rare. The publications regarding amphibian data of the Anura order, especially in the Cibodas Resort, have not been found. This Study aimed to determine the diversity of amphibians of the Order Anura in the Cibodas Resort tourist route. This research was an exploratory research conducted from September to October 2021. The research method used the Visual Encounter Survey method combined with the Line Transect method by following a predetermined path. The data was retrieved through the form of primary data (number of species of the Order of Anura in the Cibodas Resort tourist route). Based on the results of research at 3 sites, 12 species from 6 families were found with 192 individuals. The diversity index is classified as moderate with a value of 2.15, the evenness index is classified as high with a value of 0.86, and the dominance index is classified as low with a value of 0.14. The species that dominate in the 3 observation sites are from the family Ranidae namely Odorrana hosii and Huia masonii, the family Rhacophoridae namely Rhacophorus margaritifer and the family Dicroglossidae namely Limnonectes kuhlii and L. microdiscus

Etnobotani Pandan (Pandanaceae) Di Taman Nasional Bukit Duabelas, Jambi [Pandans (Pandanaceae) Ethnobotany in the Bukit Duabelas National Park, Jambi]

This research was aimed to study ethnobotany and the diversity of Pandanaceae that utilized by the people of Orang Rimba tribe who lives in Bukit Duabelas National Park, Jambi. The results of this study showed there were six species of two genera (Benstonea and Pandanus)that were used for habitual and religion activities of those tribes. Only four species were used for crafts, especially mat and wallets (sumpit):Pandanus furcatus Roxb.; Pandanus labyrinthicus Kurz ex Miq.; Pandanus immersus Ridl.; and Benstonea atrocarpa (Griff.) Callm. & Buerki. Two species were used as a ceremony's complement materials and tribe's rituals: Pandanus labyrinthicus Kurz ex Miq. (ritual of marriage), and Benstonea atrocarpa (Griff.) Callm. & Buerki to kiding (the procession before the rice planting season begins).Only one species that was used as a material for the house's or cottage's roof, Benstonea kurzii (Merr.) Callm. & Buerki. Leaves were the part of the plant which used for the Orang Rimba daily needs.The skill for making handicraft were obtained iterally from generations. The population of pandan assumed to be decreased without effort for the cultivation and conservation

Inventarisasi Jamur Makroskopis di Jalur Pendakian Kawah Ratu Taman Nasional Gunung Halimun Salak

Di Indonesia, penelitian mengenai Jamur masih belum banyak dilakukan. Hal ini membuat minimnya informasi tentang keanekaragaman Jamur, sehingga perlu adanya kegiatan eksplorasi. Oleh karena itu, penelitian ini dilakukan untuk menginventarisasi Jamur makroskopis khususnya di jalur pendakian Kawah Ratu Taman Nasional Gunung Halimun Salak (TNGHS). Penelitian ini menggunakan metode jelajah. Data yang diamati meliputi data primer dan data sekunder. Identifikasi Jamur menggunakan alat bantu berupa buku identifikasi, jurnal yang relevan, aplikasi, dan website identifikasi Jamur. Hasil penelitian menunjukkan bahwa di kawasan jalur pendakian Kawah Ratu TNGHS terdapat 59 spesies Jamur dari 2 divisi yang berbeda, yaitu Divisi Ascomycota yang meliputi satu famili dan 2 spesies, serta Divisi Basidiomycota yang meliputi 18 famili dan 57 spesies

Performansi Hutan di Berbagai Tipe Kategorisasi Hutan Adat Berdasarkan Kelembagaan Masyarakat Adat.

Studi terdahulu menunjukkan adanya perbedaan hasil peran kelembagaan adat dalam menjamin kelestarian sumberdaya hutan. Oleh karena itu penelitian tentang performansi hutan pada hutan milik masyarakat adat masih menjadi kajianpenting untuk dilakukan di berbagai daerah. Setiap masyarakat dengan berbagai macam kebudayaan memilikikelembagaan tersendiri dalam hal pengelolaan hutannya. Penelitian ini menjelaskan performansi hutan yang dimilikimasyarakat adat. Pengambilan data dengan cara wawancara semi terstruktur, observasi lapangan dan pengukuran tegakanhutan. Pendekatan menggunakan analisis kelembagaan dan analisis performansi hutan. Hasil penelitian berdasarkanpengetahuan lokal masyarakat (local knowledge) menunjukkan bahwa terdapat nilai, norma terkait dengan pengelolaanhutan yang diwujudkan dengan berbagai bentuk kategorisasi hutan. Analisis performansi menunjukkan hutan-hutan yangmereka miliki secara ekologi termasuk kategori hutan yang stabil (balanced forest)

Potensi Liken sebagai Bioindikator Kualitas Udara di Kawasan Sentul Bogor

Polusi udara merupakan salah satu masalah lingkungan yang terjadi di perkotaan terutama di daerah dengan kepadatan lalu lintas yang tinggi. Liken sangat peka terhadap parameter lingkungan seperti suhu, kelembaban, angin dan polusi udara sehingga dapat dijadikan sebagai bioindikator pencemaran udara. Penelitian ini bertujuan untuk mengetahui jenis liken yang dapat dijadikan sebagai bioindikator untuk memonitoring kualitas udara di Kawasan Sentul Eco Edu Tourism Forest. Metode penelitian yang digunakan adalah deskripif eksploratif, Pengambilan data liken dilakukan di tiga lokasi secara purposive sampling yaitu memilih secara sengaja lokasi yang dianggap memiliki tingkat polusi yang berbeda berdasarkan tingkat aktivitas manusia. Luas pengamatan liken dilakukan pada permukaan kulit batang pohon secara melingkar setinggi ±150 cm dari permukaan tanah, Analisis kandungan logam berat yaitu timbal (Pb) dan kromium (Cr) dengan metode Atomic Absorption Spectrophotometer (AAS). Hasil penelitian menunjukkan bahwa terdapat Sembilan jenis liken yang berhasil diidentifikasi dengan dua jenis tipe tallus yaitu Foliose dan Crustose. Jenis Parmelia paling sedikit ditemukan dan merupakan jenis liken yang sensitif sedangkan jenis liken Cryptochenia effusa ditemukan paling banyak dan terdapat pada semua lokasi pengamatan sehingga jenis ini tergolong toleran terhadap Perubahan kualitas udara. Berdasarkan akumulasi Pb dan Cr pada tallus, jenis Parmelia lebih banyak mengakumulasi Pb dan Cr dibanding jenis Crypthocenia dan Physcia
