Abstract

Forest fires in peat soils will affect hydrological characteristics and hydrological cycles. Industrial Plantation Forest in Riau Province is mostly located in peat soil. This study aims to measure the impact of forest fires on peat subsidence and water table level. The research location is located in industrial forest plantation located in Bengkalis Regency , Riau Province. The method of research is to install piezometer and iron rod stuck into the soil to penetrate the mineral soil layer, then the iron that appears on the surface of the soil is made permanent sign for reference in monitoring the altitude cha nge of the surrounding surface (subsidency). The fire peat forest has a depth of 12.21 cm month-1down water level from the peat surface while in the unburned area 10 cm month-1. In the burnt area the rate of peat surface decline is 0.159 cm month-1 while the unburned area is 0.119 cm month-1.

Abstract

Scarcity of agarwood trees in natural forests cause agarwood trade of all species be included Aquilaria malacensis into CITIES (Convention on International trade in Endangered Species of Wild Fauna and Flora) and limited exsport quota. Agarwood is a resinous wood and has the benefit of such ingredients as perfumes and medicines. High economic value of Eaglewood cause increased community interest for cultivation of Gaharu plants. This research was done in January to March 2015 in Pangkalan Baru, Siak Hulu subdistrict and Kuapan, Tambang subdistrict, Kampar district, Riau Province. The materials used were map, related research, camera , GPS, compass, altimeter, measuring tape, hagameter, talysheet, etc. Field of observations with searching information about cropping in cultivation of agarwood, identification of farmers and cropping patterns. Survey of agarwood tree conducted by purposive sampling method. Data obtained by making a plot with measuring 20 x 20 m plated on transect with sampling intensity by 20%. The results of research on cropping pattern was monoculture and multiculture. Multiculture was in the rubber plants. The age of agarwood trees in monokultur was 19 years old., whereas multiculture between 2-5 year. Potential agarwood trees in monocultural was 19 m³ but multicultue can not be due to plant cause age>5 years.

Abstract

This study aims to determine the understory in Eucalyptus pellita's stands. Understory are one of the elements of the ecosystem which are hold rainwater into the soil, prevent erosion,  runoff and soil organic matter. The  method used 20 x 20 m of 5 plots with 10 the number of sub-plots in the sample size of 2 x 2 m (50 sub-plots). All of understory  were  identified. There are 18 species from 17 families classified into 4 groups of the understory (grasses, sedges, ferns and broad-leaved plants). The results showed  18 types of understory which classified in 13 species of broadleaf plants, 3 species of grasses, 1 species of sedges and 1 species of ferns. The understory  was dominated by Alang-Alang (Imperata cylindrica) with INP  61.33%, followed by Teki Grass (Cyperus sp) with INP 35.67% then Acacia (Acacia sp) with INP 21.67% and ferns (Neprolepsis sp) INP 17.8%. The Diversity of understory in Eucalyptus pellita was 1.76 in the medium category.

Abstract

The presence of insect pests has an important effect on the success of plant maintenance. The level of attack caused by insect pests can cause plants to die. The purpose of the study was to analyze agarwood plants that were attacked by insect pests and identify the types of insect pests that attack agarwood plants. The research method used is descriptive. The assessment of the level of damage to agarwood plants due to insect pests is calculated based on the criteria for damage caused by insect pests. Identification of insect pests is carried out directly in the field based on the activity of insects that damage agarwood plants. Based on the results of the identification of insect pests that damage agarwood plants, there are 5 types of insect pests, namely the type of White Flea (Pseudococcus sp.), Leaf Caterpillar (Heortia viitessoides), Pitama hermesalis, Coreidae and Locusta migratoria. The insect pest attack rate is 2.3% and is included in the low category. It is necessary to intensive monitoring can insect pest attacks. If the insect pests found, they should clean up the environment from pests
