Abstract

Biodiversity assessment, even in natural forest production has become one important view to consider the balanced ecology in order to maintain productivity function. Most recent studies indicated the partial approach to biodiversity valuation then would provide occurmultiple or difference view. This study aims at identifying the biodiversity important factors as assessment tools on lowland tropical forest by ecological quantitative parameters approach. The study was conducted on Labanan forest research station as lowland tropical forest that is located in Berau district East Kalimantan Province. Data collecting from permanent research plots that consist of 3 variations of logged over forest with different logging techniques and primary condition as control with total area of 48 ha, which measurement conducted periodically every two years along 24 years. Arrangement of ecological important variables based on fluctuation values of the quantitateive dimension which included: density (number of stems), basal area, number of species, shannon diversity index, species abundance, richness index andevenness index. To identify important variables of performance characteristics of biodiversity assessment using by factor analysis basedon Bartlett's Test of Sphericity with value of KMO (Kaiser Meyer Olkin) then the principal component dispersion using Biplot analysis.  Determination of important variables based on minimum coefficient variance with total proportion cumulative percentage >80% and eigenvalue >1. The tendency towards of important ecological parameters as biodiversity assessment approach of lowland tropical forest stands after logging could be concluded by 2 important factors are evenness index and species abundancy value.  Key words: biodiversity, ecological, lowland tropical forest, quantitative parameters

Abstract

Parentage analysis has been used to evaluate pollen dispersal in ebony (Diosphyros celebica Bakh.). The objectives of this research were to evaluate (i) the dispersal of pollen, and (ii) the distance of pollen travel in ebony Lasitae provenances. The finding of this activities should be beneficial to support breeding of this ebony tree. There were 14 progeny arrays were harvested from 3 female parents. There were 32 ebony trees surrounding the female parents were analyses as the potential male parents for the progenies. Ebony tress were mapped according to their GPS position. All samples were genotyped using four SSR marker loci. Parentage analysis was done using CERVUS version 2.0 software. Results of the analysis indicated the evaluated markers were effective for assigning candidate male parents to all evaluated seedlings. There is no specific direction of donated pollen movement from assigned donor parents to the female ones. The donated pollens could come from assigned male parents in any directions relative to the female parent positions. Pollen dispersal pattern of ebony female parent occured in outcrossing pollination among its different donated trees. Based on the progenies analysis, ebony female parent is a dominantly outcrossing pollination species. Distances of pollen travel reach to 18 until 269 meter.Key words: Ebony, ssr marker, pollen dispersal.

Abstract

Soybeans is one of important food sources in Indonesia mainly as protein resources. The needs of soybeans which increasing and lower number of cultivation land causes soybeans import. Soybeans productivity improvement could be done by agroforestry system. Mindi and sentang are a fast growing species which famously cultivated at this time. One of benefit gained from agroforestry system is providing sources of organic material. Planting combination between mindi and sentang with soybeans could give organic material such as from mindi leaves and sentang leaves. This research aimed to examine the response of soybeans growth to the additional of leaves. The experimental design used was Complete Random Design (CRD) with single factor and seven treatments (control, dry whole, dry chopped, dry powder, wet whole, wet chopped, and wet powder. This research shows that the addition of sentang leaves does not impact to the diameter and height growth. The additional of mindi leaves give not significantly different to the growth of soybeans diameter, total dry mass, and total wet mass. The additional of sentang leaves give effect to the growth of number of leave, total wet mass, total dry mass and total pud mass. The additional of mindi leaves give significant impact to the height, number of leaves, and pot mass. The treatment give best impact to total pud mas was sentang dry leave chopped and mindi dry leave whole.Key words: Agroforestry, Azadirachta excelsa, Glycine max, Melia azedarach

Abstract

The mangrove forests are a type of salt tolerant vegetation, living in tidal zones in tropical and subtropical coastalareas with unique ecosystem that have a strategic function as a connector and counterweight of terrestrial and marineecosystems. Mangrove forests are a productive ecosystem and they have complex functions, such as physical functions,biological functions and socio-economic functions. Fishery resources of mangrove forests are very productive, bothquantitatively and qualitatively, because the mangrove forests act as the natural habitat (spawning, nursery and feedinggrounds) for various species of fish, shrimps and crabs, as well as a source of germplasm and genetic pool. Mangroveforests also provide valuable ecosystem services to coastal communities, tourist attractions, nature conservation,education and research. However, these ecosystems are fragile because it is very sensitive to environmental changes,usually because anthropogenic influences; therefore, it is difficult to be restored. In addition, these ecosystems are soopenly accessible that easily exploited by humans; this can reduce its quality and quantity. Local communities who usemangrove forests and their resources may have considerable botanical and ecological knowledge about their forests.Silvofishery techniques in aquaculture are very suitable for community-based mangrove forests conservation efforts.Silvofishery is an integrated model that considers both economically benefit and conservation.Key words: mangrove conservation, sustainable fisheries, community-based

Abstract

One way to establish forest conservation is by improving the welfare of the community residing at the forests’ borders. Beekeeping has the potential to increase the income of the people around the forest. This study aims to delineate beekeeping zones bordering the forest regions. Multi-criteria analysis based geographic information system was used to delineate the ecologically suitable areas for honey bees. The parameters used included physical parameters (temperature, rainfall, distance from water source and altitude), economic parameters (distance from the roads and distance from the market) and social parameters (land use and distance from settlements). The parameters were weighed by applying analytical hierarchy process. The result was then inputted into a spatial model designed to determine the ecological suitability for honeybees. The suitable land for bees’ forages was delineated using land suitability analysis with maximum limitation method. The results of both analyses were then overlaid to delineate suitable areas for beekeeping. The analysis resulted in locating recommended areas for the cultivation of honey bees and forages around the forest periphery, by taken into account official spatial land use planning.Key words: Habitat suitability, land suitability, bee forage, land use planning

Abstract

A web-based Geographic Information System (GIS) has been built by previous researchers to visualize hotspots data in Indonesia. That GIS still has not contained a hotspot analysis module. Data mining method can be used to analyze hotspot data. This research aims to develop and to integrate a clustering module of hotspot in GIS which has been developed in the previous research. The clustering module for grouping hotspot data was built using the DBSCAN algorithm with PHP programming language. Clustering hotspot data was performed based on year, month, and province. Clustering parameters are epsilon and minimum points (MinPts). Epsilon value that used ranged from 0.01 to 0.1 while MinPts ranges from 1 to 6. The clustering results are shown in form of table which consists of the attribute Province, Regency, Latitude, Longitude and Cluster. Cluster column is the final result of clustering using algorithm DBSCAN. The attribute cluster represents clusters are visualized using the map of Indonesia that was built using MapServer. Visualization can help parties involved in making effective and efficient decisions to prevent forest fires.Key words: clustering, DBSCAN algorithm, geographic information system, hotspot

Abstract

Mistletoe is hemiparasitic plants (macroparasite) on seasonal and annual plants include trees, however, mistletoes are also beneficial as key species that fill in the ecological niche, and a potential to non-wood forest product such as medicinal plants as one of them. The objectives of this research are to identify species of teak mistletoes at Padangan Clonal Seed Orchard (CSO) in Perum Perhutani and to aim its posibilities as medicinal plant. The inventory methods on species of teak mistletoes was carried out in compartements/blocks of teak clones that are designated as Observation Sample Plots (OSPs/PCP) of the attack intensity from low, medium, high, control; and four units Observation Measurement Plots (OMPs/PUP) on each OSPs/PCP. Continously, it was analized by comparing the same species of mistletoes on other host trees as reference which was efficacious to be used as medicinal plant. Three species of mistletoes parasitizing teak clone stands were identified as Dendrophthoe pentandra (L.) Miq. of family of Loranthaceae which is also attacking other host trees, Macrosolen tetragonus (Blume) Miq. of family of Loranthaceae too, Viscum articulatum Burm. F. of family of Santalacea/Viscaceae that is hyperparasite on two other mistletoes. The comparison with the same teak mistletoe but on different host trees shows that including D. pentandra and V. articulatum have the potential for hypertension treatment. D. pentandra is used too for medicine to cure ilness, wounds, fester and recovery from parturition. Known that chemical content this mistletoe comprise of flavonoid ingrident, fenolat acid (terulat acid, para hidroksi benzoate acid, kumarat acid, protokatekuat acid and vanilat acid. As for the utilization of M. tetragonus hasn’t been discovered up to this moment.Key words: mistletoe, identification, teak clone, non-wood forest product, medicinal plant

Abstract

Peatland fire research has been on the increasing trend since 1997/1998 when fire episode experienced by Indonesia and ASEAN region. Its impact on transboundary haze pollution has not merely related to environmental but on social and political issues. Since then, research on peatland fire has been on local and global concerns. International scientific journals on peatland fire in the period of 1997-2014 were reviewed and analysed descriptively. The study shows that in the earlier stage, researches covered peatland fire characteristics, fire behaviour, fire causes and fire impacts on peat and biodiversity in limited area. Research concerns had been broadened to ecological, economical, social aspects, and even political aspects. Greater impacts on transboundary haze pollution had attracted scientists to study on haze-air pollution relationship with special concern on health and economical aspects. Moreover, peatland fire and climate change issues including greenhouse gas (GHG) emission had been covered and become an iconic topic of peatland fire studies. Geographycally, almost all peatland fire studies focused in Sumatera and Kalimantan.  In the last two decades period, peatland fire researches had been explored and developed to spatial analyses on fire prone areas mapping, modelling on fire occurence prediction, haze trajectory, hotspot accuracy as fire indicator, and the latest issue was burned area estimation in relation to predict GHG emission. Key words:  peatland fire, transboundary haze, hotspot, climate change, emission
