<p>Central Kalimantan Province covers an area of 15,38 million ha which consist of 61,140 ha coastal region, 1,53 million ha open waters, and 13,79 million ha as inland area. The continental area consisted of various type of lands e.g. acid sulphate, peats soil, and up land. In order to explore and conserve potential medicinal plants indigenous to Central Kalimantan, these exploration and characterization activities were conducted. Method of study: (1) exploration, (2) ex situ conservation, (3) characterization, and (4) documentation. The result of these activities are ex situ collection of 15 acessions of medicinal crops. This exploration obtained 15 accessions of medicinal plants which were characterized and conserved in ex situ condition.</p><p> </p><p><strong>Abstrak</strong></p><p>Kalimantan Tengah memiliki luas wilayah 15,38 juta ha yang terdiri dari 61,1 ribu ha daerah pantai, 1,53 juta ha daerah perairan umum, dan 17,79 juta ha daratan. Wilayah daratan yang luas ini terdiri atas berbagai tipologi lahan seperti lahan sulfat masam, gambut, dan lahan kering. Untuk menggali potensi dan melestarikan plasma nutfah tanaman obat spesifik Kalimantan Tengah telah dilaksanakan kegiatan eksplorasi dan karakterisasi. Dari kegiatan ini dapat disusun deskripsi berbagai jenis tanaman tersebut untuk inventarisasi, karakterisasi, dan koleksi tanaman obat secara ex situ dalam bentuk kebun pembibitan. Metode kegiatan meliputi (1) eksplorasi, (2) konservasi ex situ, (3) karakterisasi, dan (4) dokumentasi. Hasil kegiatan adalah koleksi secara ex situ tanaman obat sebanyak 15 aksesi.</p>
Plankton are organisms (animals and plants) that live floating or floating in the water column, their movement is influenced by currents. The role of plankton is very important in aquatic ecosystems, especially phytoplankton which are primary producers. This research is a quantitative descriptive study using purposive sampling method with a field and laboratory survey approach. The purpose of the study was to describe the abundance and diversity of plankton in the waters of the Tasilaha Lagoon. This research was conducted in June – July 2022. The results of the study were 31 types of plankton consisting of 17 types of phytoplankton and 14 types of zooplankton. The abundance of phytoplankton species obtained ranged from 366–5,597 cells/liter and zooplankton 623–5,515 individuals/liter. The value of the phytoplankton diversity index was 2.44–2.55 and the zooplankton ranged from 2.19–2.31.
Kegiatan ini bertujuan meningkatkan wawasan dan kemampuan calon mahasiswa PPL Program Studi Pendidikan Biologi dalam penggunaan aplikasi zipgrade untuk pemeriksaan lembar jawaban siswa. Hal itu dimaksudkan agar memudahkan calon mahasiswa PPL dalam memberikan evaluasi dan memeriksa hasil evaluasi tersebut. Untuk mencapai tujuan tersebut, maka perlu dilakukan pendekatan berupa pelatihan bagi calon mahasiswa PPL. Kegiatan pelatihan yang dilakukan ini bertujuan untuk memanfaatkan smartphone dan program aplikasinya yang disebut dengan zipgrade untuk mempermudah dan mempercepat proses pemeriksaan hasil dari bentuk penilaian tes multiple choice. Kegiatan pelatihan ini dihadiri oleh 15 peserta yaitu calon mahasiswa yang akan melaksanakan PPL di berbagai sekolah yang ada di Kota Palu. Aplikasi zipgrade dapat diunduh secara gratis di playstore. Materi yang diberikan pada kegiatan pelatihan ini mulai dari pengenalan software atau aplikasi pemeriksa lembar jawaban hingga cara pemanfaatan aplikasi tersebut. Dengan adanya kegiatan pelatihan ini maka diharapkan calon mahasiswa PPL telah mampu menggunakan aplikasi Zipgrade dan menerapkannya pada proses pembelajaran di sekolah.
Species and cladystic of butterflies is closely related to the preservation and utilization of biological resources in Indonesia. This study aims to determine species and cladystic of butterflies (Lepidoptera) in Grand Forest Park Central Sulawesi. Sampling of butterflies using a sweeping net with a purposive sampling method at three different watershed (DAS) locations, namely Vatutela, Kawatuna, and Poboya. Butterfly samples obtained at the research location were then identified at the Biology Laboratory, Faculty of Teacher Training and Education, Tadulako University. The results showed that there were 97 species from 5 butterfly families, namely Papilionidae (14 species), Pieridae (16 species), Nymphalidae (46 species), Lycanidae (15 species), and Hesperiidae (6 species). The research sample used for the analysis of kinship is 23 species from five butterfly families that dominate the research location. The observed characters included 32 characters. Analysis of kinship was calculated using the Sorensen similarity index, then processed using the Multivariate Statistical Package (MVSP) software. The closest kinship relationship is between the species Appias ithome and A. zarinda which is supported by a similarity index above 0.90 and the farthest relationship occurs between the species Bibasis sp. with other species from the Hesperiidae family which were supported by a similarity index below 0.7.
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.
