(Pinus Jungh et de Vriese) and Rasamala (Altingia excelsa Noronha). Supervised
by DENI ELFIATI and DELVIAN.
Litter is a layer consisting of dead plant parts were spread on the surface of the
land is under forest before the materials decompose. Experiencing litter
decomposition is performed by soil microbes thus speeding up the nutrient content
of soil available for plants. purpose of this study was to determine the types of
fungi are capable of overhauling the leaf litter on Pine (Pinus Jungh et de Vriese)
and Rasamala (Altingia excelsa Noronha). The results obtained litter decomposer
fungi were 9 types of Trichoderma sp, Aspergillus sp1 and sp2 Aspergillus,
Aspergillus sp3, sp4 Aspergillus, Mucor sp, Penicillium sp1, sp2 Penicillium,
Rhizopus sp and Trichoderma sp. Macroscopically visible through litter
decomposer fungal colony growth, whereas microscopically with the aid of a

Fungi (AMF) for Plumbun (Pb) Metal Content on Sengon (Paraserianthes
falcataria), supervised by DELVIAN and DENI ELFIATI.
Timbal (Pb) is an environmental contaminant that risk for human’s health,
reducing soil fungtion and productivity and damage for plants. Therefore,
remediation is need to do such as bioremediation using AMF and sengon as a
host. A research was conducted to knowing the effect of the addition of AMF for
Pb content on Sengon in green house of Agriculture USU. Analyze of Pb metal
was done at Research Laboratory of Pharmacy USU on October 2014- February
2015 using faktorial completely randomize design with two faktors, i.e Pb
addition (0 and 400 ppm) and doses of mycorrhiza inoculation (0, 25 and 50 g).
Parameters measured were root colonization, plant height, stem diameter, root
drying weight, crown drying weight, crown root ratio, root Pb content, crown Pb
content and soil Pb content after harvest.
The results showed that Pb addition affected significantly on plant height,
Pb content on root, crown and soil after harvesting parameter. Inoculation of
mycorrhiza affected significantly on plant height, stem diameter, drying weight of
root and crown. Inoculation of mycorrhiza did not significant on Pb content but
capable to increasing Pb content on root, crown and soil. The interaction of the
two faktors did not affected significantly on all parameters.46 HalamanSkripsi Sarjan

Fungi on Highland and Lowland Oil Palm Field. Supervisied by DENI ELFIATI
and DELVIAN.
The goal of this research is to know the existence and the status of Arbuskular
Mycorrhiza at Oil Palm ecosystems in highland and lowland. Soil sample has
been taken from Adia Nangka Village, District of Lae Parira, Region of Dairi and
Batang Terap Village, District of Perbaungan, Region of Serdang Bedagai. This
research use soil separating method to obtain spores and root coloring method to
find out root colonization. The trapping result with host of Zea mays obtained an
average spore density on the highland is 938 spores/50 g soil, while the lowland
obtained 128 spores/50 g soil. The result shows on the highland obtained 14
spores types of Glomus genus and 6 spores types of Acaulospora genus with up to
37% colonization percentage. Lowland obtained 7 spores types of Glomus genus
and 3 spores types of Acaulospora genus with up to 25% colonization percentage51 HalamanSkripsi Sarjan

Sinabung in Karo district. Supervised by DENI ELFIATI and
DELVIAN
Volcanic ash released when the eruption has a pH that is acidic, thus
affecting the number and activity of microorganisms in the soil. Therefore
conducted this study to determine the activity of soil microorganisms in the former
eruption of Mount Sinabung in Karo. Measurement of total soil microorganisms is
done by using Agar Cawan metod, while the measurement of the activity of soil
microorganisms was conducted using jar and measured by titrimetic method. The
result of the research showed that the higher of the PH then the amount of
microorganism are getting so much and instead. As well as , the higher of C-
organic then so higher activities of micro organism in the soil and instead too.
Value respiration on land affected by volcanic ash of Mount Sinabung at a depth
of 0-5 cm is 0.96. Value respiration on land affected by volcanic ash of Mount
Sinabung at a depth of 5-20 cm is 1.16. Value respiration on land that is not
affected by volcanic ash of Mount Sinabung is 1.52.51 HalamanSkripsi Sarjan

Arbuskula Fungal. Under the guidance of DELVIAN and BUDI UTOMO.
Industrial Forest Plantation in Indonesia, one of them used type of
acacia. Land for Industrial Forest Plantation in Indonesia generally critical land,
which will be nutrient poor. To improve soil fertility to increase the input of
nutrients, and nutrients are usually a factory made fertilizers are expensive. One
attempt to minimize the cost of artificial fertilizer use is to use Mikoriza Arbuskula
Fungal (MAF). These fungal help plants to absorb nutrients. This research aims
to study the growth responses of seedlings Acacia spp few to FMA. This research
using completely randomized factorial design with 2 factors arbuscular and
acacia species. The results showed there was no interaction between the
arbuscular and types of acacia (0.05 level). However, the acacia species have real
impact on, broad leaves, and the total of leaves.69 halamanSkripsi Sarjan

inoculation and watering interval on growth of seedling suren (Toona sureni
Merr.) Supervised by DELVIAN and NELLY ANNA.
The objective of this research was to detemine the growth response of seedling
suren (Toona sureni) by adduction Arbuskula Mycorrhizae Fungus (AMF) and the
watering interval. The research was done in the greenhouse of Faculty of
Agriculture, University of Sumatera Utara, Medan. The research used a factorial
completely randomized design with two factorials the mycorrhizae dosage (0
g/seedling,5 g/seedling, 10 g/seedling and 15 g/seedling) and the second factor
with four rates of watering interval consists of once in a day, once in 3 days, once
in 5 days and once in 7 days. The results showed that mycorrhizae inoculation did
not significantly affect for height, diameter, leaf area, root crown ratio, and total
dry weight of plant except and phosphor plant uptake the percentage of root
colonization. Watering interval significantly influenced all parameters except
phosphor plant uptake. The interaction between inoculation mychorrhizae and
watering interval only significantly affect the percentage of root colonization.
Mycorrhizal treatment dose 15 g / polybag is the best treatment and the treatment
of watering intervals of 3 days is the best treatment.66 HalamanSkripsi Sarjan

The research aims to test seedling growth responses Pulai (Alstonia scholaris) by
adduction Arbuskula Mycorrhizal Fungus (AMF) and the watering interval. The
research was done in the greenhouse in Faculty of Agriculture, Sumatera Utara
University, Medan. This study uses a factorial completely randomized design with
two factorials the mycorrhizae dosage (0 g/seedling,10 g/seedling,20 g/seedling
and 30 g/seedling) and the second factor with four rates of watering interval
consists of once in 1 day, once in 3 days, once in 6 days and once in 9 days. The
results showed that mycorrhizae inoculation did not significantly affect for height,
diameter, number of leaf, total dry weight of plant except the root crown ratio and
the percentage of root colonization. Watering interval significantly influenced all
parameters except total dry weight of seedlings. The interaction between
inoculation mycorrhizae and watering interval only significantly affect the
percentage of root colonization.55 halamanSkripsi Sarjan
