Judul: Selection and Characterization of Bacteria Inhibiting the  Growth of Fusarium sp. Derived from the Tomato Plant (Solanum lycopersicum L.).  (Solanum lycopersicum L.).
Abstrak: One of the problems in tomato (Solanum lycopersicum L.) farming is the emergence of wilt disease, which is caused by the fungal pathogen Fusarium sp. Pathogenic fungi have been controlled by spraying synthetic fungicides. The use of fungicides has a negative impact on other organisms and the environment. The negative impact of excessive use of synthetic chemicals can be reduced by using biocontrol agents that produce antifungal compounds. Efforts to control pathogenic fungi naturally using rhizosphere bacteria to control the growth of pathogenic fungi on tomato plants (Solanum lycopersicum L) have not been widely reported. This study aims to select rhizosphere bacteria from 14 bacterial isolates that have been isolated from tomato farming which are able to inhibit the growth of Fusarium sp. in vitro and characterize selected bacteria. The results of the bacterial antagonist test against the fungus Fusarium sp. with the dual culture method showed that 6 out of 14 isolates were able to inhibit the growth of the fungus Fusarium sp. Isolates TTSG 2.2, TTSG 2.7, TTSG 3.2, TTSG 3.5, TTSG 3.6, and TCS 3.1 had inhibitory power of 45%. One of the six isolates of rhizosphere bacteria, namely TTSG 3.6, showed a negative reaction in the hemolysis test. These results indicate that the bacterial isolate of TTSG 3.6 has the potential to be used as a control for Fusarium sp. on tomato plants, Salah satu masalah dalam pertanian tomat (Solanum lycopersicum L.) ialah munculnya penyakit layu, yang disebabkan oleh cendawan patogen Fusarium sp. Cendawan patogen selama ini dikendalikan dengan menyemprotkan fungisida sintetik. Pengunaan fungisida berdampak negatif terhadap organisme lain dan lingkungan. Dampak negatif dari penggunaan bahan kimia sintetis berlebihan, dapat dikurangi pengunaannya dengan agens biokontrol yang menghasilkan senyawa anticendawan. Usaha pengendalian cendawan patogen secara alami menggunakan bakteri rizosfer sebagai pengendali pertumbuhan cendawan patogen pada tanaman tomat (Solanum lycopersicum L) masih belum banyak dilaporkan. Penelitian ini bertujuan untuk menyeleksi bakteri rizosfer dari 14 isolat bakteri yang telah diisolasi dari pertanian tanaman tomat yang mampu menghambat pertumbuhan Fussarium sp. secara invitro dan melakukan karakterisasi bakteri terpilih. Hasil uji antagonis bakteri terhadap cendawan Fusarium oxysporum dengan metode dual culture menunjukkan bahwa sebanyak 6 dari 14 isolat mampu menghambat pertumbuhan cendawan Fusarium sp. Isolat TTSG 2.2, TTSG 2.7, TTSG 3.2, TTSG 3.5, TTSG 3.6, dan TCS 3.1 memilki daya hambat 45%. Satu dari enam isolat bakteri rizosfer yaitu TTSG 3.6 menunjukkan reaksi negatif dalam uji hemolisis. Hasil ini menunjukkan bahwa isolat bakteri TTSG 3.6 berpotensi digunakan sebagai pengendali Fusarium sp. pada tanaman tomat

Judul: Efikasi Bakteri Endofit dan Plant Growth Promoting Rhizobacteria dalam Menekan Perkembangan Penyakit Layu Bakteri (Ralstonia solanacearum) pada Tomat
Abstrak: Tomato (Lycopersicum esculentum Mill.) is a popular vegetable in Indonesia, but the production levels are still fluctuated. One of the factors affected productivity is the incidence of bacterial wilt disease caused by Ralstonia solanacearum. Effective control to manage the disease which is environmentally friendly is the use of biocontrol agents. Application of endophytic bacterial (Staphylococcus epidermidis BC4) and Plant Growth Promoting Rizhobacteria (Pseudomonas fluorescens RH4003 and Bacillus subtilis AB89) as biocontrol of tomato bacterial wilt was expected to be an alternative tool. The objective of this study is to determine the efficacy of combination among endophytic bacteria and PGPR to suppress the development of bacterial wilt disease (R. solanacearum) and promote the growth of tomato. Depend on the growth test (growth rate and dry weight plant), the combination of bacteria that could promote the growth of tomato plant was combination of S. epidermidis BC4 75% with P.fluorescens RH4003 25%. That combination gave a better effect than the other treatments and control, but did not provide better suppression than treatment of single bacterium. Based on sinergism test, the relationship between PGPR and endophytic bacteria was an antagonistic. However, there were combination treatments which were able to suppress the disease, ie. combination of S. epidermidis BC4 50% with P. fluorescens RH4003 50% and the combination of S. epidermidis BC4 50% with B. subtilis AB89 50%.

Abstrak: Industri perkayuan memegang peranan penting terhadap perolehan devisa dan pembangunan ekonomi negara. Sejalan dengan penuruan ketersediaan bahan baku untuk industri dan meningkatnya biaya tenaga kerja pada industri berbasis kayu maka mebel kayu merupakan industri kecil yang berpeluang untuk dikembangkan. Industri mebel kayu tidak hanya diharapkan untuk memperoleh devisa tetapi juga akan menstimulasi pertumbuhan ekonomi nasional karena memiliki nilai tambah yang tinggi, mempunyai keterkaitan yang cukup kuat dengan sektor lain, menciptakan lapangan kerja, memiliki pertumbuhan pasar yang baik, dan berdaya saing cukup tinggi. Data statistik UN COMTRADE (2008) mermperlihatkan bahwa sektor industri mebel terus mengalami peningkatan ekspor mebel dari tahun 2003 sampai tahun 2007. Negara tujuan ekspor mebel Indonesia yang utama adalah Amerika Serikat (37%), Jepang (12%), Inggris (8%) dan Belanda (8%), Jerman (7%), dan Perancis (7%). Selain itu, ekspor juga ditujukan ke negara-negara Italia, Belgia, Spanyol, dan Australia.
