Abstract

Mount Sipiso-piso is an Old Volcanic Mountain and part of the Lake Toba Catchment Area (DTA). The location of the Forest on Mount Sipiso-piso is unique because the site of the Forest is at the top of Mount Sipiso-Piso. The area below the mountain is a dense Forest that stands in the peak area of Mount Sipiso-Piso has a role in maintaining water flows in the Mount Sipiso-Piso area, becoming a place for rainwater absorption, and maintaining ecosystem stability so that erosion or landslides do not occur in vulnerable areas. This study aimed to look at the diversity and evenness of Mount Sipiso-piso Forest vegetation types. Data analysis techniques include Important Value Index (INP), Diversity Index (H'), and Evenness Index (E). The results showed that 20 families and 23 plant species from 1539 individuals were found in the field. The Important Value Index (INP) indicates that different individuals dominate the forest community at each level. The index of the diversity of Mount Sipiso-Piso Forest vegetation is categorized as moderate in the saplings, poles, and trees class and the low category in the undergrowth, woody shrubs, and seedlings class. For the species evenness index, the category is expected in the undergrowth and seedling class, the medium type is in the woody shrub and tree class, and the high sort is in the sapling and pole class.Keywords: Sipiso-Piso Mountain, Forest, Vegetation, Diversity, Evenness.

Abstract

Taxonomic study on Pandanus (Pandanaceae) in swamp area, Singkil had been conducted from November 2012 until June 2013. Based on morphological characters,  5 species of Pandanus have been identified in the area  as  Pandanus atrocarpus, Pandanus labyrinthicus, Pandanus militaris, Pandanus odoratissimus and Pandanus tectorius. The morphology and life cycle of species were categorized into two types, and they are medium arborescent pandan  (Pandanus labyrinthicus and Pandanus militaris) and large arborescent pandan (Pandanus atrocarpus, Pandanus odoratissimus and Pandanus tectorius).  Anatomical characters of Pandanus such as stomata (type, size, papilla) and epidermal cells supported the morphological features.

Abstract

Sampah organik dan sampah plastik dapat menimbulkan masalah bagi lingkungan, karena membuat lingkungan menjadi kotor dan bau.  Untuk mengatasi masalah ini maka sampah organik dan sampah plastik tersebut diolah menjadi produk lain. Kegiatan ini dilakukan oleh Kelompok Tani Pondok Miri pada bulan Mei 2022. Tujuan kegiatan ini adalah untuk mengimplementasikan praktik daur ulang sampah plastik dan memanfaatkan sampah rumah tangga sebagai medium tanam dan pupuk untuk tanaman obat guna meningkatkan nilai jual dan pendapatan di antara masyarakat, yang diilustrasikan melalui studi kasus di kelompok tani Pondok Miri Asri, Desa Sei Semayang, Sunggal, Deli Serdang. Daur ulang sampah plastik dilakukan dengan menggunakan pipa paralon, botol bekas yang multifungsi untuk menanam tanaman obat, serta galon/gelas air mineral untuk menanam tanaman obat. Pengumpulan sampah plastik, seperti botol plastik, bungkus makanan, bekas pembungkus minyak, bekas gelas plastik, dan sejenisnya, dilakukan di Desa Sei Semayang, Kecamatan Sunggal, Kabupaten Deli Serdang untuk dijadikan wadah tanam bagi tanaman obat.
