Effectiveness of Fungal and Bacterial Isolates from Rhizosphere of Passion Fruits againts Fusarium oxysporum f. sp passiflorae in Vitro
Fusarium wilt caused by Fusarium oxysporum f.sp passiflorae is the most important disease on passion fruit that causes yield losses ranging from 50 to100%. The disease is difficult to control because the pathogen systematically infected plants and can survive up to five years in the soil in the absence of its hosts. The objective of this paper was to select potential antagonistic microbes in suppressing the growth of Fusarium oxysporum f.sp passiflorae (Fop) in vitro. Antagonists were isolated from the rhizosphere of purple passion fruit (Passiflora edulis form edulis) and sweet passion fruit (Passiflora sp) from Gowa and Makassar. To obtain the best isolates, their ability to inhibit the growth of Fop and their production of cellulase, chitinase, pectinase as well as toxine compound were tested in vitro. The results showed that out of 22 fungal and bacterial isolates tested, four and three isolates respectively, gave an excellent growth inhibition to Fop. Highest percentage of growth inhibition was provided by fungal isolate U1 (86.11%) and bacterial isolate Mb2 (76.44%). The highest cellulase, chitinase and pectinase enzyme production were observed on fungal isolate U1, followed by isolates U7, M1, M2 and M4. Only two bacterial isolates Ub1 and Mb3 showed highest cellulase, chitinase and pectinase enzyme production. The presence of toxin was detected by using a thin layer chromatography on fungal isolates U1, M4 and Mb3. HCN compound from bacterial isolates were obtained from isolates Ub1 and Mb3
PENGARUH STRUKTUR KEPEMILIKAN DAN STRUKTUR MODAL TERHADAP KEBIJAKAN DEVIDEN PADA PERUSAHAAN MANUFAKTUR YANG TERDAFTAR DI BURSA EFEK INDONESIA (BEI) TAHUN 2007-2008
Kebijakan deviden bersangkutan dengan penentuan pembagian pendapatan antara
penggunaan pendapatan untuk dibayarkan kepada para pemegang saham sebagai
deviden atau untuk digunakan di dalam perusahaan. Ada dua hal yang menetukan
keputusan kebijakan deviden, pertama keputusan yang diambil oleh pemegang
saham, dan struktur modal yang digunakan dalam perusahaa.
Penelitian ini menggunakan sampel perusahaan manufaktur yang terdaftar di BEI
sejak tahun 2007-2008. Dengan kriteria terpenting adalah memiliki struktur
kepemilikan managerial dan institution, dan membagikan devidend. Pada
penelitian ini didapat 15 perusahaan yang memenuhi kriteria penelitian. Objek
dalam penelitian ini adalah struktur kepemilikan sebagai variabel X1 yang diukur
dengan jumlah prosentase saham yang dimiliki oleh manajemen pada akhir tahun
dan jumlah persentase saham yang dimiliki oleh institusi pada akhir tahun dan
struktur modal sebagai variabel X2 diukur dengan melihat leverage, sedangkan
kebijakan deviden sebagai variabel Y yang diukur dengan ratio pembayaran
deviden (dividend payout ratio).
Hasil penelitian ini menunjukan bahwa variabel managerial, institution dan
leverage secara simultan berpengaruh signifikan terhadap variabel devidend
payout ratio. Secara parsial variabel Institution dan leverage berpengaruh secara
signifikan terhadap variabel DPR. Sedangkan variabel managerial tidak
berpengaruh signifikan terhadap variabel DPR. Secara bersama-sama variabel
managerial, institution dan leverage memberikan sumbangan 20.4% dalam
menjelaskan DPR, sedangkan sisanya sebesar 79,6% dijelaskan oleh faktor-faktor
lain diluar model. Dari hasil tersebut maka manajemen dapat memperhatikan
faktor Institution dan leverage sebagai prediksi untuk menentukan kebijakan
deviden.

Dividend policies concerned with determining the distribution of revenues
between the use of revenues to be paid to shareholders as dividends or for use
in the company. There are two things that determine the dividend policy
decisions, the first decision taken by the shareholders, and capital structure
used in company.
This study uses samples of manufacturing companies listed on the Stock
Exchange since the year 2007 to 2008. With the most important criteria is to
have the managerial and ownership structures Institution, and the dividend
payment. In the study showed the 15 companies that fulfilled the criteria. The
object of this research are as variable ownership structure, as measured by
the number of percentage of shares held by management at the end of the
year and the number of percentage of shares owned by institutions at year
end and capital structure as a variable measured with leverage, while the
dividend policy as a variable y as measured by the ratio of dividend payment
(dividend payout ratio).
The results of this study show that managerial variables, Institution and
simultaneously leverage significant effect on dividend payout ratio variable.
Partially Institution and leverage variables significantly affect the dividend
payout ratio variable. While the managerial variables did not significantly
influence the dividend payout ratio variable. Taken together managerial
variables, Institution and leverage contributed 20.4% in explaining the
dividend payout ratio of 79.6% while the rest is explained by other factors
outside the model. From these results, the management may consider the
factors as a prediction Institution and leverage to determine dividend polic
