The Indonesian Selective Cutting and Planting Silvicultural System (ISCP) has beenapplied to manage natural production forests since 1989. This system was revised in1993 and 2009. This study aims to determine the condition of natural forests afterlogging at PT Bina Multi Alam Lestari, Central Kalimantan Province. The study wasconducted using the plotted plot method proportionally in P-8 Block of RKTUPHHKHA at 2021. The results showed that the structure and composition of the vegetation inthe forest after being harvested using the TPTI silvicultural system at PT Bina MultiAlam Lestari was still well maintained. The meranti tree group dominated the tree levelbefore and after harvesting with INPs of 141 and 135.56, respectively, as well as for thepole level with INPs of 108.56 and 106.33, respectively. Meanwhile, at the seedling andsapling levels, other commercial groups (non dipterocarps) were dominated. Speciesdiversity are high with a range of values of H' 3.1 to 3.3 and species richness rangedfrom moderate to high with a range of values from 3.94 to 6.68. The level of vegetationdensity is still well maintained and is above the standards set by the Ministry ofEnvironment and Forestry. The distribution of vegetation diameter in the forest beforeand after harvesting still resembles the condition of mixed natural forest (unaged standforest) with an inverted J pattern. Natural forest harvesting activities using the TPTIsilvicultural system at PT Bina Multi Alam Lestari in the RKTUPHHK-HA Block in2021 did not cause significant damage and environmental conditions are still wellmaintained.Keywords: Natural forest, Important Value Index, diversity, richness, density
印度尼西亚选择性采伐和种植造林系统(ISCP)自1989年以来一直用于管理天然生产林。该制度在1993年和2009年进行了修订。本研究旨在确定加里曼丹省中部比纳多阿拉姆勒斯塔里天然林采伐后的状况。该研究于2021年在RKTUPHHKHA的P-8区块按比例进行。结果表明:TPTI造林系统采伐后，林内植被结构和组成仍保持良好;在采前和采后水平上，莫兰蒂组的INPs分别为141和135.56，在竿水平上，INPs分别为108.56和106.33。在苗木和幼树水平上，其他商业类群(非龙心科)占主导地位。物种多样性高，在3.1 ~ 3.3之间;物种丰富度从中等到高，在3.94 ~ 6.68之间。植被密度水平仍然保持良好，高于环境和林业部制定的标准。采伐前后森林植被直径的分布仍与混交林(未老化的林分)相似，呈倒J型分布。2021年，在RKTUPHHK-HA区块的PT Bina Multi Alam Lestari使用tptir造林系统进行的天然林采伐活动没有造成重大破坏，环境条件仍然保持良好。关键词:天然林，重要价值指数，多样性，丰富度，密度

Dunia fungi atau jamur merupakan salah satu kekayaan hayati yang juga merupakan hasil hutan non kayu yang kini memberi peluang ekonomi yang berarti bagi masyarakat. Jamur memiliki keunikan yang memperkaya keanekaragaman jenis makhluk hidup dalam dunia tumbuhan. Sifatnya yang tidak berklorofil menjadikannya tergantung kepada makhluk hidup lain, baik yang masih hidup maupun yang sudah mati. Jamur juga memegang peranan penting dalam proses alam yaitu menjadi salah satu dekomposer unsur-unsur alam, beberapa jamur tertentu telah dimanfaatkan oleh manusia, baik sebagai bahan makanan maupun bahan obat.. Penelitian ini bertujuan untuk mengetahui keanekaragaman jenis jamur dari kelas Basidiomycetes di Stasiun Riset Punggualas Taman Nasional Sebangau Kabupaten Katingan Kalimantan Tengah. Metode yang digunakan dalam eksplorasi jamur ini yaitu metode sensus pada 8 jalur dalam plot penelitian berukuran 150m x 200m. Analisa data dengan menghitung indeks keragaman jenis, indeks dominansi dan indeks kemerataan. Pengamatan dilakukan terhadap karakteristik, substrat dari masing-masing jamur serta data iklim di Stasiun Riset Punggualas. Hasil penelitian menunjukkan terdapat 28 jenis jamur dari 8 famili dari kelas Basidiomycetes. Jamur yang dominan adalah jenis Ganoderma sp sehingga dapat dikatakan bahwa jenis jamur Ganoderma sp sebagai penciri dari hutan rawa gambut di Stasiun Riset Punggualas. Jamur yang termasuk jenis yang dapat dikonsumsi adalah jamur kuping (Auricularia sp), jamur tiram (Pleurotus ostreatus), jelly fungi (Tremellaenchephala), kulat enyak (Oedemansiella sp) serta yang termasuk jamur obat adalah Ganoderma lucidum.

Sengon (Paraserinthes falcataria (L) Nielsen) is a fast-growing plant that is widely cultivated by people in dry land. Currently, the cultivation of this plant is also mostly carried out on unflooded peat swamp land in Central Kalimantan. Utilization of peat swamp land has good prospects because this land is rich in organic matter as a source of plant nutrition. This study aims to determine the growth of sengon plants and create a plant growth model to predict the diameter and height of plants at a certain age. The research was conducted in Pulang Pisau Regency, Central Kalimantan Province. The model used to predict the growth of sengon plants is a polynomial equation. The results showed that the growth of sengon plants planted in unflooded peat swamp land at the ages of 6, 13, 30, 36, 48, and 56 months namely 3.76 cm; 7.07 cm; 12.94 cm; 13.91 cm; 18.76 cm; and 22.88 cm respectively for diameter (dbh); 4.64 m; 9.70 m; 11.45 m; 12.16 m; 14.75 m; and 15.20 m respectively for shoot height; and 2.37 m; 4.13 m; 4.85 m; 5.28 m; 5.62 m; and 6.21 m respectively for branch-free height. Sengon plant growth model with polynomial equations is y = -0.01802 + 0.739x - 0.0157x2 + 0.0002X3; y= 0.6002 + 0.893x - 0.0236x2 + 0.0002x3; and y = 0.5676 + 0.3777x - 0.0106x2 + 0.0001x3 for diameter (dbh), shoot height and branch-free height, respectively. The equation is valid and has high accuracy so that it can be used to predict diameter, shoot height and branch-free height of sengon plants until the age of 56 months.

The purpose of this study (a) determine the composition and structure of vegetation based on the growth rate (tree, pole, sapling, seedling) in each Permanent Sample Plot (PSP); (b) to calculate the potency of biomass and carbon in vegetation trees level, poles and sapling on each PSP. The results showed that the number of vegetation species found in PSP-1 as many as 47 species with 28 family and PSP-2 of 33 species with 24 family. The vegetation of species that dominate based on the level of growth (tree, pole, sapling, seedling) in the PSP-1 consists of : Gerunggang (Cratoxylum arborescens (Vahl) Blume) and Jambu-jambu (Syzigium sp). In PSP-2 of vegetation species that dominance Tumih (Combretocarpus rotundatus (Miq.) Danser) and Jambu-jambu (Syzigium sp). The structure of the vegetation horizontally in the PSP-1 and PSP-2 dominated the vegetation of the small diameter and structure of the vegetation vertical in the dominance of vegetation including the stratum D. The average value the species diversity indexs vegetation tree level, pole, sapling and seedling in PSP-1 at 2.09 included in the category of “medium” and in PSP-2 of 1.83 which is included in the category of “low”. The potency vegetation biomass total in PSP-1 and PSP-2 respectively 152.69 tons/ha and 122.93 tons/ha as well as the potency carbon vegetation total in PSP-1 and PSP-2 respectively 71.76 tons/ha and 57.78 tons/ha.
本研究的目的是(a)根据每个永久样地(PSP)的生长速率(树、杆、树苗、幼苗)确定植被的组成和结构;(b)计算各样地植被、树木水平、极和树苗的生物量和碳潜能。结果表明，PSP-1有28科47种，PSP-2有24科33种。以生长水平(乔木、杆子、树苗、幼苗)为主的植物种类包括:gerungang (Cratoxylum arborescens (Vahl) Blume)和Jambu-jambu (Syzigium sp)。在以Tumih (Combretocarpus rotundatus (Miq.))为优势的植被种的PSP-2中。舞蹈)和Jambu-jambu (Syzigium sp)。在包括d层在内的植被优势层中，PSP-1和PSP-2的植被水平结构以小直径植被和垂直结构植被为主。PSP-1的植被树级、极、树苗和幼苗物种多样性指数平均值为2.09，属于“中等”类别，PSP-2的物种多样性指数平均值为1.83，属于“低”类别。PSP-1和PSP-2的有效植被生物量总量分别为152.69 t /ha和122.93 t /ha, PSP-1和PSP-2的有效碳植被总量分别为71.76 t /ha和57.78 t /ha。

Rinjani Scops Owl (Otus Jolandae) is an endemic fauna that is included in the family of owls that are found in several forests that have been in the boundary or in the ecosystem of Mount Rinjani. The latest report published by IUCN in 2016 on the Rinjani Scops Owl (Otus Jolandae) is included in the Near Threatened (almost threatened) category. The purpose of this research is to know the population and characteristics of the trees perched Rinjani Scops Owl (Otus Jolandae) in several public forest lines Wanalestari Karang Sidemen village, Central Lombok. The method used in this research is divided into preliminary studies and primary research, where preliminary studies have been a method of literary studies, interviews, and observations. Then the main research has the IPA (Index Point Of Ambudance) method, measurement Of environmental physical condition, and vegetation structure with single compartments. Analysis of the user data is quantitative and qualitative. Results showed that the total population of Rinjani Scops Owl (Otus Jolandae) across the observation line in Hkm Wanalestari amounted to 16 individuals with an density of population each between 0,76-1,27 ha. The tree of the perched Rinjani Scops Owl (Otus Jolandae) consists of six types, namely the Dadap (Erythrina variegata) tree, Jackfruit (Artocarpus Heterophyllius), Durian (Durio zibethinus), Pecan (Aleurites moluccanus), Randu (Ceiba pentandra) and avocado (Parsea americana). The height of the Tengger tree ranges between 5-9 meters, diameter between 31,4-76,6 cm, and an area of heading 31,7-113,4 m2. The average temperature of Rinjani Scops Owl (Otus Jolandae) habitat of 25.4-25.6 °C humidity 76,4-76,6% and light intensity ranged from 0.9-4.68 Lux.
