Abstract

Utilization of rhizosphere microbes such as arbuscular mycorrhizal fungi (AMF) and mercury-resistant bacteria (MRB) is one of the alternative technologies that can be used synergisti-cally to overcome the main problem in biologically rehabilitation of marginal and mercury (Hg) contaminated tailings in ex gold mining area. The research was aimed to get an effective combination of AMF isolates (Glomus sp. SS11, Glomus sp.SS15, Glomus sp.SS18) with MRB isolates (Bacillus sp. HgTA1 and Pseudomonas HgRA) in supporting seedlings growth of sengon laut (Paraserianthes falcataria (L.) Nielsen) and sengon buto (Enterolo-bium cyclocarpum Griseb) in mercury-contaminated tailings. Dual inoculation of Glomus sp. SS15 with Bacillus sp. HgTA1 or Pseudomonas sp. HgRA isolates; dual inoculation of Glomus sp. SS18 with Bacillus sp. HgTA1 or Pseudomonas sp. HgRA isolates; single inoculation or dual inoculation of Glomus sp. SS11 with Pseudomonas sp. HgRA isolates were proven to be very effective in increasing P. falcataria seedlings height. However, only single inoculation of Bacillus sp. HgTA1 isolate was effective in increasing E. cyclocarpum seedlings height. Hg accumulation in plant tissue of P. falcataria and E. cyclocarpum, either with or without rhizosphere microbial inoculation, indicated that both plants were highly potential as Hg phytoextraction or phytostabilization agents.  Key words: arbuscular mycorrhizal fungi, Enterolobium cyclocarpum Griseb, mercury, mercury-resistantbacteria, Paraserianthes falcataria (L.)

Abstract

Land management refers to land use activities by local community in order to meet the necessities of life. The aim of this study to reveal the management model in Nusapati and its services and to find out about public perception of the different models for land management such as forests, community forests, gardens and rice fields. The research was conducted from May to June 2016 through field observation with a Focus Group Discussion (FGD) using research tools such as interview guides. The results show that the four models of the land are used for subsistence either directly (economic and social purposes) or indirectly (ecological). Respondents prefer the garden as a model of the most important land with a score of 34%, followed by community forest with a score of 25% third after community forest is rice field with a score of 23% and finally is a forest with a score of 18%. The results of the analysis show that the average public is it the institution, age, education, and gender has no differences on the model of land that is important to meet their needs. Meanwhile, the community forest is not necessarily considered to meet the daily need given the harvest time is quite long. The plant species that exist in the community lands are quite varied so as to provide considerable benefits for the community and the environment. Keywords: community, community forest, Land management.

Abstract

Insects are the most dominant group of animals living on the face of the earth and their role is ecologically significant. The purpose of the study was to observe the type of population and identify the effect of  water level on the diversity of insect species found in the peat swamp area of Kuala Dua village. Data assesment was done by using survey method with systematic sampling. Observation plots was adjusted to the field conditions with water level 30, 40, 50 and 60 cm. The results showed that there were 15 insects species  belonging to 8 orders from 11 different families. The most common insects found in various TMAs that were observed, were Neurothemis fluctuan from the Odonata order. Physical conditions of the environment greatly affect the life of insects, such as having many types of plants which became food  for insects. It can be concluded that the level of diversity of insect species has a relationship with environmental conditions such as vegetation, pH, and water level.Keywords: Insect population, systematic sampling, water level

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 : Gold mining, Monterado Sub district, Succession.

Abstract

Tanjungpura University Forest for Special Purpose located in three districts Landak Regency, Mempawah Regency and Kubu Raya Regency. Has the potential to use and process non-timber forest products. The diversity of macroscopic fungi is not yet known as one of the potential natural biological resources of significant value. So that a mushroom inventory must be carried out to identify and assess the diversity of macroscopic fungi. The method used is the survey method. Data retrieval uses a double plot sampling technique. The size of each observation plot is 5 m × 5 m as the initial reference, four plots in the peat swamp forest area with open canopy cover conditions and also four observation plots in peat swamp forest areas with canopy cover conditions are still closed. Placement of research plots in both areas was carried out purposively in locations where there were many types of macroscopic fungi. The results showed that the types of macroscopic fungi found at the study site were 24 species. 24 species were divided into 594 individuals belonging to 23 genera and 9 families. Macroscopic fungi found in open canopy cover were found in 17 species, while in closed canopy cover there were 13 species. In both types of conditions the place to grow has the same 6 types of fungi. The degree of diversity of macroscopic fungi in various conditions the peat swamp in Tanjungpura University Forest for Special Purpose is low.Keyword: Macroscopic fungi, peat swamp forest, Tanjungpura University Forest for Special Purpose.

Abstract

Pulai (Alstonia scholaris) is a local species and fast-growing plant that can be used in plantation development activities. The aim of this study was to obtain information on the growth and quality response of seedlings on growing media (a mixture of ultisol, cocopeat, chicken manure and husk charcoal) and organic vinegar (wood vinegar, peat vinegar and fern root vinegar). The research was carried out at the Kasa Rumah Pamer Room and Orchid Market Institute for Research and Service to the Tanjungpura University Community and at the Silviculture Laboratory of the Faculty of Forestry. This study uses an experimental method with split plot design with a completely randomized design (CRD) archetype. The treatment consisted of two factors, namely growth media (ultisol + cocopeat + chicken manure and ultisol + cocopeat + chicken manure + husk charcoal) as the main factor and organic vinegar (chemical fertilizer, peat vinegar, wood vinegar and fern root vinegar) as plot factor. The results showed that the mixed media of ultisol + cocopeat + chicken manure significantly affected the height of pulai seedlings by 55.4 cm (1.28 fold), 6.7 mm diameter (3.35 times) and number of seedling leaves 62 , 25 (1.34 times) of planting media with rice husk charcoal. Organic vinegar has no significant effect on the growth and value of the quality of pulai seed quality index.Keywords: growing media, organic vinegar, pulai seedlings

Abstract

The research was to obtain information about the combination of fertilizers in the production of arbuscular mycorrhizal inoculums of various depths. This research is using an experimental method. The research uses divided plot design (RPT) with a basic RAK pattern. The treatment factor consists of the main plot (peat depth 0-50 cm and 50-100 cm) and subplot is a combination of fertilizer (P1 = without fertilizing; P2 = NPK+rubberwood vinegar; P3 = NPK+peat vinegar; P4 = NPK+fern-root vinegar). Spore breeding process is ± 3 months. Hosts use sorghum with sterile sand media. The observation variable consisted of the percentage of root infections and the number of spores. Data analysis using ANOVA. Identification of spores based on morphology and Melzer reaction. The results showed that fertilization factors affected the number of spores. The number of spores without fertilization was higher, namely 1642,500 spores compared to combination fertilizers (NPK+fern-root vinegar was 707,667 spores; NPK+rubberwood vinegar was 606,833 spores; NPK+peat vinegar was 206,667 spores). The rate of 0-50 cm colonization without fertilization, NPK+peat vinegar, NPK+rubberwood vinegar is included in the high category. Then in the treatment at 50-100 cm without fertilizing, NPK+peat vinegar, NPK+fern-root vinegar infection rates are also high. The type of spore found is Glomus sp.1; Glomus sp.2; Glomus sp.3; Glomus sp.4. The results of the number of spores and the percentage of root infections showed that organic vinegar was known to not stimulate FMA sporulation, but organic vinegar did not inhibit FMA colonization.Keyword: Mycorrhizal, organic vinegar, peat depth, sorghum
