abstract: The productivity of oil palm plants often declines, marked by the emergence of
basal stem rot disease caused by the fungus Ganoderma boninense, which increases
the percentage of plant mortality by 50-80%. The aim of this research is to
determine the effect of the column chromatography fraction of porang chloroform
extract and the concentration of the fraction on the growth of G. boninense fungus.
This research was conducted using a Completely Randomized Design (CRD) with
six levels and three replications. Five fractions were tested against the growth of G.
boninense at a concentration of 1000 ppm, and the best fraction was further tested
at various concentrations. The concentration of fraction-1 is 0.25 ppm (K1), 0.50
ppm (K2), 0.75 ppm (K3), 1 ppm (K4), 1.25 ppm (K5), and 1.50 ppm. (K6). Data
was tested for homogeneity using the Bartlett test and for data addition using the
Tukey test. Next, the data were analyzed using variance analysis and significance
tests, as well as further tests using the BNT test at a 5% level. Based on the test
results, it was found that the chromatography column fraction of the chloroform
extract of porang affected the growth inhibition of G. boninense in fraction 1 by
43.7%. The best concentration of the fraction produced in fraction 1, which was
1.50 ppm, achieved the highest inhibition rate of 61.54% and a slow growth rate of
0.24 cm/day, categorized as slightly harmful.

Produktivitas tumbuhan kelapa sawit seringkali mengalami penurunan yang
dintandai dengan munculnya penyakit busuk pangkal batang yang disebabkan oleh
jamur Ganoderma boninense sehingga meningkatkan persentase kematian
tanaman sebesar 50-80%. Tujuan dari penelitian ini untuk mengetahui pengaruh
fraksi kolom kromatografi ekstrak kloroform porang serta konsentrasi fraksi
terhadap pertumbuhan jamur G. boninense. Penelitian ini dilakukan menggunakan
Rancangan Acak Lengkap (RAL) dengan enam taraf dan tiga kali ulangan. Lima
fraksi diuji terhadap pertumbuhan G. boninense pada konsentrasi 1000 ppm dan
fraksi terbaik dilakukan uji lanjut pada berbagai konsentrasi. Konsentrasi fraksi-1
yaitu 0,25 ppm (K1), 0,50 ppm (K2), 0,75 ppm (K3), 1 ppm (K4), 1,25 ppm (K5),
dan 1,50 ppm (K6). Data diuji kehomogenan dengan uji bartlett dan kemenambahan
data dengan uji tuckey. Selanjutnya, data dianalisis ragam dan uji signifikan serta
uji lanjut menggunakan uji BNT pada taraf 5%. Berdasarkan hasil uji didapati
bahwa fraksi kolom kromatografi ekstrak klorofrom porang berpengaruh terhadap
daya hambat pertumbuhan G. boninense pada fraksi 1 sebesar 43,7%. Konsentrasi
fraksi terbaik yang dihasilkan pada fraksi-1 yaitu 1,50 ppm memperoleh daya
hambat tertinggi 61,54% dan laju pertumbuhan yang lambat 0,24 cm/hari dengan
kategori sedikit berbahaya.
