Plant Protection Sungai Putih Research Center since July to September 2008. The
aims of the research was to know different resistant rubber comersial klons to 3
rd
isolate fall of leaf disease (C. gloeosporioides Penz. Sacc.). The research used the
method of complete factorial random design with 40 combine of treatmentand 3
repeats. Clones that used were BPM 24, PB 260, BPM 1, RRIC 100, PB 330,
IRR 118, IRR 104, BPM 107, BPM 109, PB 217. C. gloeosporioides isolate from
Sumut (Sungai Putih), Palembang (Sembawa), Jawa tengah (Salatiga), and control
(used aquadest steril). The result of research showed that the clone BPM 109 (K9)
is a resistant clone, clone BPM 24 (K1) is a moderat clone, and the other clones
were is a middle resistant. Periode latent to all isolate except control to 2 hsi was a
clone BPM 24 and BPM 1. Isolate from Salatiga showed a high virulence if
compared with isolate from Sembawa, Sungai Putih and Control.57 HalamanSkripsi Sarjan

Plasmodiospora brassicae Wor. Soilborne disease that cause clubroot at relatives of Cruciferae family generally and mustard especially. This Disease cause very seriously loss and that influence production result and it uncontrollable. Therefore this research was done to know how giving T. koningi
Bult. To clubroot P. brassicae Wor. At mustard B. juncea. This research used RAK non factorial methode whit 6 treatment:
A: Cultivated land mustard without conidia Trichoderma koningii (control).
B: Cultivated land mustard with 10° conidia T. koningii
BCDEF : Cultivated land mustard with 10' conidia T. koningi : Cultivated land mustard with 10° conidia T. koningili
: Cultivated land mustard with 10° conidia T. koningi : Cultivated land mustard with 1010 conidia T. koningi
This research indicate that T. koningii conidia aplication has an actualy effect to percentage of clubroot P. brassicea Wor. As much intencity at conidia as highter effectivity it gives. The lowes attact persentage is 0% at intencity treatment conidia 1010 (F)

Ir. Mukhtar Iskandar Pinem as the leader of , Mr Ir. Kasmal Arifin Msi as
participant dan Mr. DR. Agus Susanto as participant. This research use survey
methode which has been done in PT. Anak Tasik Tanjung Selamat Estate that
known as Peatlands. Then, for the sample’s tester has been done in Laboratory of
Indonesian Oil Palm Research Institute. As the purpose of this research is to
know the characteristic of Ganoderma boninense at the Oil Palm in Peatlands
which use Polymerase Chain Reaction (PCR) methode. From the research that
has been done, known that there is the different of Ganoderma at the oil palm in
peatlands in the mineral land. The attack of Ganoderma in PT. Anak Tasik in
block B8 with 29,5 hectar wides which is the peatlands, usually through
basidiospora that caused upper stem rot that archive 63 % (82 plants), and only 37
% (49 plants) that is basal stem rot. For generally the attack of Ganoderma in PT.
Anak Tasik archive 0,96 % (895 plants) from 94.945 plants which has 766,01
hectar wides. Based on the of fruiting body (basidiokap), the research of pure
mycelium, micrograph mycelium and basidiospora and the moleculer tested, so
we know that the attack of the disease in Oil Palm in PT. Anak Tasik caused by
