Abstract

Shorea javanica was a high dependent plant to ectomycorrhizal symbiosis, dealing with its growth. In Lampung Province, S.javanica standing stock have been hundreds of years, known as repong damar.  It's threatened by some deforestation, such as forest fire.  This study aimed to analyze the impact of heating on the ability of ectomycorrhizal colonization and analyze the effect of ectomycorrhizal inoculation on the growth of S. javanica.  The experiment arranged by randomized complete design with 5 treatments, which were without inoculum, unheated inoculum, soil inoculums heat to 40oC, 70oC and 100°C for 24 hours. Soil inoculums are taken under S. javanica standing, at Krui, Pesisir Barat District, Lampung Province. The result analyzed by ANOVA and continued with LSD test.  The experiment was conducted for four months.  The results show that colonization ectomycorrhiza still existed up to 100oC and ectomycorrhiza could enhance growth variables, including height, leaves number, leaf area, root length and root dry weight. The best colonization and growth were on 100oC heating. The heat treatments seem killed some fungus.  Only a few fungi could resist and colonize S. javanica roots.  Without any competitors, the resist ectomycorrhizal could develop broadly.

Abstract

Bioherbicide is an alternative compound to control weeds which are environmentally friendly by utilizing parts of plant organs, like leaves that are applied in the form of extracts. The aim of this study is to determine the potential of Terminalia catappa, Swietenia macrophylla, and Filicium decipiens leaf extract as bioherbicides against Cyperus rotundus and to find out which leaf extract has the most effective to prevent the Cyperus rotundus growth. The study was done by using maceration techniques of leaf extract with ethanol solvent applied to Cyperus rotundus. This study was designed in a Completely Randomized Design (CRD) consisting of 4 treatments, which are control, 50% of Terminalia catappa leaf extract concentrate, 50% of Swietenia macrophylla leaf extract concentrate, and 50% of Filicium decipiens leaf extract concentrate. The results of this research showed that ketapang, mahogany, and kerai payung leaf extract could be used as bioherbicides because it has a very significant effect on inhibiting the height growth, the number of leaves, and the length of the roots of Cyperus rotundus. Filicium decipiens extract was the most effective extract in inhibiting the number of Cyperus rotundus leaves. However, each leaf extract did not significantly affect the reduction of chlorophyll content and dry weight. Therefore, further research is needed regarding the potential of these three leaf extracts to other weeds.

Abstract

Agarwood has so high value that can trigger an excessive agarwood encroachment in nature; it threatened the agarwood availability. Agarwood cultivation was the right solution to overcome the Agarwood insufficiency. Currently, bioserum has been found to form Agarwood rapidly. It was found by Kusnadi and introduced to the public by BPDASHLWSS (The watershed management and protection forest inquiry). The formation and effectiveness process of bioserum has not been researched yet scientifically. Therefore, this study aimed to determine the success rate of Agarwood formation and the quality of Agarwood with combined injections treatments on tree branches of Aquilariamalaccensis. This research used a complete randomized design with 3 treatments. Each treatment consisted of several vertical injection hole spaces: 5 cm, 10 cm, and 15 cm. The horizontal space for these three treatments was the same, 5 cm.  The result showed that the best vertical range of injection was 10 cm. Therefore, each injection hole would produce separate agarwood chips. A 10-cm vertical range injection also made the rest wood between the injection holes not too wide. This Agarwood was classified into kamedangan class with the average weight of 2 g/chips.

Abstract

The increasing needs and the nearness residential distance from the forest were several factors that caused society to do the utilization of the forest land. Sungai Langka village was a village directly adjacent to the Wan Abdul Rachman great forest park area, where most societies were farmers who manage the land inside the Wan Abdul Rachman great forest park area. The objective of this research i.e.: 1) To find out the species of plants cultivated by farmers on the land-based on habitus, plant groups, and commodities produced; 2) to count the density of each plant group; 3) to find out the most plants as a source of farmers incomes.  This research was conducted with a vegetation survey using the terraced line method. The number of sample plots used was 69 pieces measuring 20m x 20m, 10m x 10m, 5m x 5m, and 2m x 2m. The results of the study showed that there were  35 plants species on farmers cultivated land which is dominated by plants of the forest group MPTS with a density of 3,637.66 individuals/ha, forest wood plant 797,83 individuals/ha, agricultural MPTS 2,294.2 individuals/ha, and agricultural crops 1,533.34 individuals / ha.  Therefore, could be concluded that most of the plants on arable land were fruit-producing plants which were partially included in the MPTS forest group plants, and farmers rely on crops such as cocoa, banana, durian, clove, nutmeg, rubber, petai, pepper and vanilla as the source of income and fulfill their needs.

Abstract

Khilau Watershed (DAS) is one of the sub-watersheds with the status of should be restored. The biophysical conditions of the watershed must be assessed, to determine the suitable actions for land rehabilitation. The purpose of this study was to provide a comparative analysis of baseline data on the biophysical conditions of the Khilau Sub-watershed area based on edaphic and climatic parameters. Data collection method was using cluster sampling in five types of land cover. The data analysis used spatial and laboratory analysis. The results showed that agroforests and annual crops mostly were on moderately steep to steep slopes (15-45%) and all primary forests were in steep slopes (>45%).  All the land covers were ultisol.  The primary forest has the highest CEC, N-total, P-availability, and C-organic among other land covers.  The agroforest has the most acid pH soil among other land covers.  The primary forest has the most rapid soil permeability compared to other land covers.  The  primary forest has the lowest temperature and the highest humidity compared to other land covers

Abstract

Scarification was the destruction of the seed coat to  softening seed coat and  became permeable to water and gas. The purpose of this study was to obtain the best scarification techniques, types of growth regulatory substances and the combination of scarification treatments and addition of growth regulatory substances to accelerate the germination of Pericopsis mooniana seeds. The study was conducted using factorial randomized block design with three replications. The first factor was the scarification technique, with hot water, and broken the seed skin. The second factor  was the addition of growth regulatory substances (coconut water and, bamboo shoots) shoot water and artificial growth regulatory substances  Dates analyzed with variance and continued with the tukey test at 5% level. The results showed that the scarification technique by broken seed skin significant differences in the percentage of sprouts, germination, average days of germination, vigor index, number of leaves, and seedling height. The addition of  growth regulatory substances did not show a significant difference in all observed variables.

Abstract

Encroachment on forest areas in Indonesia occurs due to various factors mainly related to tenure issues and economic interests. That encroachment occurred in all regions of Indonesia with vary in intensity and amount. Register 47 Way Terusan which has been designated as a KPHP model Way Terusan also being occupied by squatters since the 1990s. The communities within and around the KPHP Way Terusan area has highly dependency on forest resources. The data collection is done in several ways, namely: interviews, literature searches, downloads Landsat satellite imagery and field verification activities. Landsat images Scene: Path 123 and Row 063 for the year 1994, 1999, 2004, 2009 and 2014. Data analysis was conducted using NDVI (Normalized Difference Vegetation Index) and supervised classification. The results of the analysis of land cover in 1994 until 2014 shows the intensity of dynamics of land cover change in the region KPHP Way Terusan. Land cover changes caused as a result of choice of the type of vegetation that has higher economic value. In 2014, the use of cassava cultivation was the highest (55.24%) because of its high economic value, convenient cultivation and market demand. Partnership with agroforestry pattern most likely applied as management strategy policies to accommodate the interests of various stakeholders in KPHP Way Terusan.

Abstract

This research was conducted to study about abundance and diversity of soil and litter mesofauna to the effect of forest cover change that occurred in the Pemerihan Resort, Bukit Barisan Selatan National Park. This research was compiled in a completely randomized design (CRD) and there were four different lands, which were: (1) primary forest, (2) coffee plantation, (3) corn field, and (4) grassland. The observation of mesofauna was taken in soil and litter from four different lands cover. The variable of observation were mesofauna abundance and diversity index, soil chemical properties (pH, organic carbon, total nitrogen, P available, and exchanged potassium), and soil physics properties (bulk density, soil temperature, humidity, and porosity). Data were analyzed using F test and further test using least significant differences (LSD) at 5%. The results showed that the different of lands cover affect the diversity index of litter mesofauna, the abundance of litter and soil mesofauna, yet did not affect the diversity index of mesofauna underground. However, the abundance and diversity index of soil and litter mesofauna in the primary forest was higher than the other lands.
