Abstract

Kembang telang leaf extract is antimicrobial controlling pathogenic fungi in vitro. The purpose of the study was to determine the ability of the kembang telang leaf extract as an inhibitor of the growth of fungi that cause root rot and the concentration of the extract that was most effective. The research was carried out in the Silviculture laboratory Faculty of Forestry Universitas Tanjungpura for three months. The experimental method used a completely randomized design with treatments consisting of four concentrations, namely 0%, 3%, 6%, and 9%, with three replications. Telang flower leaf extract can inhibit Ganoderma sp. An inhibition zone looks more apparent than the Telang flower leaf extract area. The growth of fungal growth at the lowest concentration of 3% is the same as effectively inhibiting the growth of Ganoderma sp. The research results imply that the flower telang leaf extract has the potential as an antifungal against the Ganoderma sp.      Keywords: antimicrobial, extract, Clitoria ternatea, Ganoderma.AbstrakEkstrak daun kembang telang memiliki efek antimikrob dalam mengendalikan jamur patogen secara in vitro.

Abstract

Critical land is a damaged land, thus losing or decreasing its function to the specified or expected limits. The identification and critical lands mapping is essential for the planning and determination of priority watersheds in order to the utilization and development of natural resources and land rehabilitation and soil conservation. Remote sensing is a technique that enable people to collect data without direct field measurement. The using of Landsat 8 image then analyzed by using Geographic Information System (GIS) is being expected to improve the ability to classify land cover, the map was then overlad with parameter map based on Regulation of Director General of Management of Watershed and Social Forestry Number P. 4 / V-Set / 2013 about technical guidance on the preparation of spatial data of other critical lands to identify critical lands in Kayong Utara Regency.Keywords: Degraded land, Geographic Information System (GIS), Remote sensing, overlay

Abstract

This study aims to obtain information about the succession levels of natural vegetation on ex – community gold mining in Monterado. The method of this research was survey method through vegetation analysis by double plot size 20 m x 20 m. Placement of plots dileberately based on the tailing period of ex – community gold mining which were : < 1 year, 2-3 years, 5-7 years, and > 10 years. The result showed that kinds of shrub found in all age level of ex – community gold mining area. The type of woody plants at the seedling found in all period of ex – community gold mining area, whereas sapling, pole and tree only found in ex – community gold mining at age level > 10 years. Based on the vegetation analysis, it showed that Ischaemum rugosum and Melastoma malabathricum L. dominanted at all age level of ex – community gold mining. Seedling in the ex – community gold mining at all age level were dominanted by Dillenia suffruticus. The index of species diversity showed that it was still low on ex – community gold mining in Monterado.Until the age of tailing > 10 years, succession was still in the level of competition, so it was concluded to be slow. To accelerate succession, revegetation, land restoration, and people awareness should be undertaken.Keyword : community gold mining, Monterado Sub district, Succession

Abstract

Gold mining activities have negatively impacted post-mining land into poor nutrients, low pH, toxic soil, due to heavy metal content, low water holding capacity, low organic matter content and unstable land conditions. To change the tailings to be more productive many of the available technologies, such as the use of manure, compost, litter or the use of soil microbes such as mycorrhiza. The addition of manure can additionally increase nutrient available, can also improve the physical and biological properties of the soil. Alaurites moluccana (L) Wild) is one of the plants classified as a pioneer species because it can grow on critical land with low soil fertility and open soil. Research on ameliorant of tailings to increase the growth of  A. moluccana  in the nursery aims to obtain a mixture of ameliorants with the tailings to enhance the growth of A. moluccana  in the nursery. Treatment was given to the growth of seedlings of A. moluccana  using the Completely Randomized Design (RAL) exprotment method with a total of 8 treatments that included an ameliorant tailing control, tailings with ameliorant a (1: 1, 1: 2, and 1: 3), tailings with ameliorant b (1: 1, 1: 2, and 1: 3) and ultisol soil control, with each treatment repeated 5 times. Data collected were shoot hight (cm), stem diameter (mm), number of leaves and dry weight of plant. The result of tailings treatment  with addition of organic ameliorant gave a very significant effect on the growth of height, diameter, number of leaves and dry weight of the A. Moluccana.  The best media treatment for all parameters is M6 (tailings: kotoran sapi 1: 3). Although virtually all treatments with organic ameliorant  provide better results than controls without the addition of organic ameliorants.Keywords: Tailings, ameliorant, A. moluccana , organic.
