Liangpran Mountain is located within the Heart of Borneo (HoB) Conservation Area which has high biodiversity. The exploration of orchids has been carried out in several locations in the HoB region and recorded a high diversity of wild orchid. This research was conducted to explore and inventory the orchids from the foothill of Mount Liangpran, and record the diversity and abundance of epiphytic orchids in the study sites. This research was carried out by making track of exploration along the Nuyung river estuary to the Tebing Lapah. The richness and abundance data were collected in three plot of 1000 x 20 m. The host tree characteristics and distribution of epiphytic orchid on the host tree were recorded. Fourteen species orchids were collected, and the most dominant are Coelogyne asperata and Agrostophyllum stipulatum with an abundance of 23.53% each. The epiphytic orchids in host trees are spread from the zone II to V based on the Johansson’s sections, in which zone IV is the most diverse. Nine species of the host trees associated with the collected orchids were identified and grouped into five families. The characters of host trees are 7–57 m height,12–112 cm diameters, and 2 types of bark surfaces (rough and intermediate).
Bad breath or halitosis is a pathologist that often experienced in the community. Bacteria that play a specific role in halitosis are anaerobic. To overcome bad breath due to the development of bacteria in the oral cavity is using Siwak spray. Siwak solution is obtained through maceration. The maceration results went through several stages of testing, namely, organoleptic, pH, and antibacterial testing through Nutrient Agar (NA). Analysis of the quantitative data obtained using the Friedman method. The organoleptic results show that the concentration of 1% that was most accepted by 76.66% of the panellists. The optimal bacterial inhibition was at a concentration of 2%. The pH for the 1% Siwak concentration was the best matches.
Suku Asteraceae merupakan suku dengan jumlah jenis tertinggi dan perawakan bervariasi. Sebanyak ± 30.000 jenis tersebar di dunia dan 150 marga diantaranya tersebar di kawasan Malesia. Jenis-jenis Asteraceae di Pulau Jawa tercatat dalam buku <em>Flora of Java</em> Jilid 2. Namun, dalam beberapa tahun terakhir terdapat beberapa jenis yang belum tercatat dalam <em>Flora of Java</em> telah ditemukan di Jawa. Penelitian ini bertujuan untuk mengungkap jenis tumbuhan rekaman baru untuk melengkapi penyusunan buku <em>Alien Flora of Java</em>. Penelitian ini dilakukan dengan metode jelajah pada Maret 2019 hingga Agustus 2020 di beberapa lokasi di Pulau Jawa. Terdapat satu jenis tumbuhan rekaman baru dari suku Asteraceae yakni <em>Centratherum punctatum </em>di Desa Galonggor Bogor dan Jatinangor yang telah ditemukan tumbuh meliar dan belum tercatat sebelumnya dalam <em>Flora of Java</em>. Jenis ini menambah data anggota <em>Centratherum</em> yang terdapat di Jawa. Pendugaan asal, penyebab meliar, pemanfaatan, serta kandungan kimia jenis ini dipaparkan di dalam tulisan.
Borneo is the second-highest diversity island for Nepenthes, with approximately comprising 23 species that were spread on this island. Species found on lowland to highland with variety habitat and ecological types. Tanjung Selor is the capital city of Bulungan Regency, North Kalimantan. Nepenthes distribution in these areas has never been reported, particularly in the heath forest. The study was conducted to report the floristic of Nepenthes in Tanjung Selor. We used a desktop study and field exploration on heath forest of Tanjung Selor in 2019 with rapid biodiversity assessment method. The preliminary report of Nepenthes in Bulungan are presented with species description, ecology, threats, illustration, and a brief disscusion regarding the species. We reported six wild species and one natural hybrid of Nepenthes based on exploration. Nepenthe’s habitat is in an open area, roadside, and heath forest vegetation. The threats are higher from habitat degradation and land conversion to agricultural land or non-agricultural uses. In this paper, we mentioned Nepenthes fusca growth in lowland habitat, commonly found in highland.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
