Using the formula for sampling intensity [IS] of 2% and a total area of 100 Ha, the number of sample plots obtained is 50. This study identified 43 families and 76 species of medicinal plants. The highest importance index (INP) of the lower plants in the lower plantswas Senduduk (Melastoma malabathricum) a value 29,797%, while the lowest INP is Cataract (Laurentia longifora), Curry Leaf (Murraya koenigii), Kumis Kucing (Orthosiphon aristatus) a 0,724%. While in INP, the highest mastery of medicinal plants at sapling level is Jelutung (Dyera costulata) a value 40.741%, while the lowest INP a butterfly (Bauhinia porpurea) with 4.204%. The diversity indexes of medicinal plants at the understorey and sapling levels were found to be 2.00 and 1.03, in both, indicating that understorey and sapling diversity was moderate and the community state was very stable. While the diversity index of medicinal plants at the seedling level was 0.94, indicating that medicinal plant diversity at the seedling stage is poor and the community state is quite poor.","PeriodicalId":344936,"journal":{"name":"Sylva: Jurnal Ilmu-ilmu Kehutanan","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128166448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to determine the growth response of 3 year old jernang rattan plants to light intensity under mixed stands. The study was carried out at KHDTK Kemampo, Palembang Environmental and Forestry Research and Development Center from June to July 2020. This study used an experimental method with a Non-Factoral Randomized Block Design consisting of 3 treatments with 9 replications. The treatments consisted of P1 = canopy closure 10–30% (light intensity 72.19%), P2 = canopy closure 40–60% (light intensity 55.63%), and P3 = canopy closure 70–90% (light intensity 23.39%). The results showed that the growth of jernang rattan gave a very good response to light intensity under mixed stands for all parameters observed, namely plant height, leaf midrib length and number of leaves, as well as leaf color. The best growth of jernang rattan is in light conditions with a canopy cover of 10%-30% (light intensity 72.19%). There is a positive correlation between light intensity and the growth of jernang rattan under mixed stands, that is, the higher the light intensity, the better the growth of jernang rattan.","PeriodicalId":344936,"journal":{"name":"Sylva: Jurnal Ilmu-ilmu Kehutanan","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116468610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Energy sources that come from fossils if we take it continuously will run out and cannot be renewed. Therefore, it is necessary to have an alternative source of renewable energy, one of the renewable energies to replace fossil energy, is wood biomass. One of the woods that can be used as a renewable energy source is Kaliandra wood (Calliandra calothyrsus). Calliandra (Calliandra callothyrsus) is a type of tree that can grow throughout the year. The problem faced in generative breeding of Kaliandra is the low seed germination caused by Kaliandra seeds having hard seed dormancy, and the skin has a waxy coating. To overcome the problem of meeting the needs of Kaliandra wood in energy resources, vegetative propagation of plants is needed, one of which is stem cuttings. This study aims to determine the level of effectiveness of the successful growth of Kaliandra stem cuttings using various concentrations of growth regulator Rootone F. The research method used is quantitative by conducting various experiments, namely treatment of Kaliandra stem cuttings without treatment, treatment using Rootone-f hormone with concentration (100 ppm), and treatment using the hormone Rootone-f with a concentration (200 ppm). The results showed that the number of shoots and the number of leaves were the same in each treatment, namely 1 shoot. The length of shoots in the Rootone F hormone treatment with a concentration of 100 (ppm), produced the largest shoot length of 0.71 cm, the percentage of life in the Rootone F hormone treatment with a concentration of 100 ( ppm) was 6.67%, and the root length of Kaliandra cuttings on Rootone F hormone treatment with a concentration of 100 (ppm) produced the largest 0.25 cm. ","PeriodicalId":344936,"journal":{"name":"Sylva: Jurnal Ilmu-ilmu Kehutanan","volume":"420 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123792753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
