Abstract

Rusa timorensisis native wildlife Indonesia which have protected status that require attention in order to preserve and utilization. This study aimed to preference level of the type of diet, and mineral nutrient content of feed in the conservation area Peucang Island. Data collection was performed by following the daily movement of deer and record all types of plants are edible. Neu indexes was used to scoring of level feed,chi square test was used to distinguish in the level of preference, and inspection of feed nutrients and minerals was done in the laboratory animal science. The results showed Cynodon dactylon, Axonopus compressus, Hibiscus tiliaceus, Dendrolobium umbellatum, Lagerstroemiawhere the types of feed most preferred by the index value of the preference of feed w> 1, there where differences in the choice of feed indicated by the chi-square test χ2count = 23.1850> χ2 (0:05, 10) = 18:31, nutritional value and mineral feed in the forests and grasslands showed no significant difference (p> 0.05). Deer in Peucang have a tendency to choose the type of feed that contains the same nutrients and minerals between feed in the forest or grassland although of a different kind.

Abstract

The purpose of this research is to identify the types and characteristics of mangroves on Gantan Island and to evaluate the environmental conditions around the mangrove locations on the island. Mangrove samples were collected through exploration around Gantan Island by closely observing the various mangrove species, taking direct photographs of leaves, roots, flowers, and fruits, and then describing their characteristics. The research results indicate the presence of 11 plant species, including 6 true mangrove species such as Exoecaria agallocha, Xylocarpus granatum, Bruguiera gymnorhizza, Avicennia alba, Sonneratia caseolaris, and 3 associated mangrove species including Acanthus ilicifolius, Hibiscus tiliaceus, and Terminalia catappa. Additionally, non-mangrove plants like grasses and Casuarinaceae trees were also found. Some observation points, such as points 1 and 7 located directly along the open sea, experienced high sea erosion due to large waves, causing damage to the natural habitat. Local residents have undertaken reforestation efforts to restore the damaged habitat. Observation point 6 also experienced sea erosion as it is situated along a large river. Meanwhile, observation points 2, 3, 4, and 5 are still areas with pristine natural conditions in accordance with the mangrove perpendicular zone.

Abstract

Penelitian ini bertujuan untuk mengetahui bentuk mikroplastik dan kelimpahannya berdasarkan kedalaman dan antar lokasi pengambilan sampel pada Sedimen di Tapak Kuda Lama dan Pantai Pulau Gantan Kabupaten Langkat. Penelitian dilaksanakan pada bulan Maret – Mei 2023. Pengambilan sampel sedimen dilakukan di Tapak Kuda Lama dan Pantai Pulau Gantan menggunakan metode purposive sampling dengan membuat 5 titik pengambilan sampel pada masing – masing lokasi dengan kedalaman 0-30, 30-60, 60-100 cm. Analisis sampel sedimen dilaksanakan di Laboratorium Biologi Universitas Negeri Medan. Identifikasi mikroplastik menggunakan mikroskop stereo dan data yang diperoleh dianalisis dengan Uji Anova One Way dan Uji-T untuk antar lokasi dan kedalaman. Hasil penelitian menunjukan bahwa bentuk mikroplastik yang terdapat pada Sedimen di Tapak Kuda Lama dan Pantai Pulau Gantan adalah fiber, fragmen dan film. Dengan kelimpahan pada setiap kedalaman di Tapak Kuda lama yaitu fiber 320 partikel/kg, film 160 partikel/kg dan fragmen 90 partikel/kg. Kelimpahan di Pantai Pulau Gantan pada setiap kedalaman yaitu fiber 350 partikel/kg, fragmen 200 partikel/kg dan film 120 partikel/kg.  Hasil analisis statistik Anova One Way dan Uji -T nilai sig. > 0.05 yang berarti menunjukkan tidak ada perbedaan kelimpahan mikroplastik antar lokasi dan kedalaman di Tapak Kuda Lama dan Pantai Pulau Gantan Kabupaten Langkat.

Abstract

Microplastics threaten the survival of aquatic organisms including fish in Lake Toba. This study aims to identify the type and abundance of microplastics found in the gills and digestive tract of tilapia (Orochromis mossambicus) in cages and non-cages of Lake Toba, Samosir Regency. Sampling was conducted in February-March 2024 at three stations namely Tanjung Bunga, Palipi, Simarsasar with sampling at each location of 10 caged and non-caged fish each. Extraction of microplastics using the Fenton. Observation parameters included gill weight, gut length, and abundance of microplastics in the gills and digestive tract. The results revealed that the majority of microplastics identified in cages and non-cages were fiber and filament types, with non-cage fish having a higher abundance of microplastics than cage fish.

Abstract

This study aims to obtain a good concentration of IBA and plantain and is suitable for root induction in Dendrobium sp. The benefit of this study is to provide information about the successful root induction of orchid plantlets Dendrobium sp. In vitro culture and creating formulations using IBA hormones and organic plantain ingredients in in vitro culture media optimally. This research has been carried out at the YAHDI Plant Tissue Culture Laboratory. Rooting orchids Dendrobium sp. In vitro using MS basic media which was added with IBA (Indole 3 Butyric Acid) 0 ppm, 2 ppm, 4 ppm, and 6 ppm, and added with plantain pulp with levels of 0 g/l, 100 g/l. and 200 g/l. This study was a factorial experiment with 2 factors compiled based on a 4 x 3 Complete Random Design (RAL) with 12 treatment combinations. The data obtained was analyzed for variance analysis (ANOVA). If there are results that have a real effect, it is followed by the DMRT (Duncan Multiple Range Test) test at the level of 5%. (1) The results of the study showed that the treatment of the variables of the number of roots, plant height, and root length was influenced by IBA. (2) The treatment of the variables of the number of buds, the number of leaves, the number of roots, the height of the plant, and the length of the roots is influenced by plantains. (3) The treatment of the variables on the number of roots, root length, and leaf width were influenced by the interaction of IBA and banana pulp.

Abstract

Indonesia menempati posisi ke 2 sebagai penyumbang sampah plastik ke laut. Hal ini juga diperkuat dengan meningkatnya timbunan sampah sebesar 74.808 ton ditahun 2025 di Kota Binjai, termasuk sampah organik dari limbah pertanian. Produksi tebu di Sumatera Utara 96% berasal dari Kabupaten Langkat yang secara tidak langsung juga menyumbang limbah. Lembaga Kesejahteraan Lanjut Usia (LKLU), tidak hanya sebagai lembaga perlindungan lanjut usia, juga sebagai penjaga warisan budaya dan lingkungan bukan hanya upacara adat tetapi berbagi pengalaman mengenai pengelolaan kebun tebu dan turunannya. Berbagai permasalahan seperti (a). Mitra belum menggali secara optimal potensi lokal (b). Minimnya pengetahuan mitra bahwa ampas tebu bisa diolah. (d). Mitra tidak tahu dampak plastik yang digunakan. (e). Mitra terbiasa mengelola sampah organik menjadi kompos, namun belum mengetahui bioplastik. Untuk memaksimalkan potensi tersebut, diadakan pelatihan berbasis kearifan lokal ampas tebu melalui tiga tahap edukasi, pelatihan/pendampingan dan evaluasi. Bahan dan alat yang sesuai mampu menghasilkan bioplastik yang layak dikembangkan. Terdapat peningkatan signifikan pengetahuan dan keterampilan peserta, ditunjukkan oleh kenaikan skor rata-rata dari 40% pada saat pretest menjadi 85% setelah pelatihan. Capaian ini mencerminkan Kegiatan ini berhasil memperkenalkan pemanfaatan limbah ampas tebu secara optimal menjadi produk inovatif dan ramah lingkungan berupa bioplastik.
