Abstrak Lumpur minyak bumi (oil sludge) memiliki kandungan kontaminan petroleum hidrokarbon terbesar, karenanya pengolahan limbah oil sludge perlu dilakukan agar tidak mencemari lingkungan. Penelitian yang menguji kemampuan jamur indigenus Riau (Penicillium sp. PN6) dan legum akuatik (Neptunia oleracea) dalam meremediasi senyawa hidrokarbon dengan pengukuran total petroleum hidrokarbon (TPH) pada limbah oil sludge telah dilakukan. Pertumbuhan N. oleracea dilakukan pada media limbah oil sludge dengan konsentrasi 25, 50, 75, dan 100%. Selanjutnya dilakukan pemberian inokulum Penicillium sp. PN6 ke dalam media pertumbuhan. Hasil penelitian menunjukkan bahwa persentase pertumbuhan N. oleracea adalah 95,58; 85,87; 25,55; dan 0%, berturut-turut pada limbah oil sludge 25, 50, 75, dan 100%. Terjadi penurunan konsentrasi TPH awal pada semua perlakuan di akhir pengamatan. Penicillium sp. PN6 meningkatkan degradasi TPH dari limbah oil sludge dibandingkan dengan kombinasi Penicillium sp. PN6 dengan N. oleracea, tetapi kombinasi Penicillium sp.PN6 dengan N. oleracea meningkatkan persentase penurunan TPH dari limbah oil sludge dibandingkan dengan menggunakan Penicillium sp. PN6 saja. Penicillium sp. PN6 dan kombinasinya dengan N. oleracea sama-sama mampu menurunkan pH limbah oil sludge.Abstract Oil sludge contains the largest contaminant of petroleum hydrocarbon that needs treatment to prevent its pollution into the environment. A study examining the ability of a Riau indigenous fungi (Penicillium sp. PN6) and an aquatic legume (Neptunia oleracea) to remediate hydrocarbon compounds by determining total petroleum hydrocarbon (TPH) in oil sludge waste has been conducted. The growth of N. oleracea was performed in the oil sludge waste media by concentrations of 25, 50, 75, and 100%. The medium was inoculated with Penicillium sp. PN6. The results showed that the percentage of growth of N. oleracea were 95.58; 85.87; 25.55; and 0%, in the oil sludge waste of 25, 50, 75, and 100%, respectively. There was a decrease in initial TPH concentration at all treatments at the end of the observation. Penicillium sp. PN6 increased more TPH degradation of the oil sludge waste compared to a combination of Penicillium sp. PN6 and N.oleracea, but the combination increased the decrease percentage of TPH compared to those that used Penicillium sp. PN6 only. Penicillium sp. PN6 and its combination with N. oleracea are both able to decrease pH of the oil sludge waste. Permalink/DOI: http://dx.doi.org/10.15408/kauniyah.v11i1. 6350

AbstrakRendahnya produktivitas lahan pertanian di Indonesia berkaitan dengan serangan penyakit tanaman, contohnya penyakit layu Fusarium pada tanaman tomat dan busuk pangkal batang pada tanaman kelapa sawit yang disebabkan oleh Ganoderma boninense. Penelitian sebelumnya telah berhasil mengisolasi aktinomisetes dari tanah Arboretum Universitas Riau, namun belum diketahui kemampuannya dalam menghambat jamur Fusarium oxysporum f.sp lycopersici dan Ganoderma boninense. Penelitian ini bertujuan untuk menguji 32 isolat aktinomisetes terhadap jamur target dengan metode difusi agar. Aktinomisetes potensial yang terpilih, dilanjutkan untuk produksi senyawa antifungi dengan lama waktu fermentasi yang berbeda (4, 5, dan 6 hari) dan diuji dengan metode difusi kertas cakram. Hasil penelitian uji aktivitas antifungi dengan metode difusi agar menunjukkan 31 isolat aktinomisetes mampu menghambat pertumbuhan jamur F. oxysporum f.sp lycopersici dan isolat A2.01 memiliki zona hambat tertinggi yaitu sebesar 36,10 mm. Sebanyak 28 isolat aktinomisetes mampu menghambat jamur G. boninense dan isolat D2.28 memiliki zona hambat tertinggi, yaitu sebesar 45,71 mm. Isolat aktinomisetes Arboretum Universitas Riau sebagian besar dapat menghambat pertumbuhan kedua jamur target dengan metode difusi agar, namun hasil uji senyawa antifungi isolat potensial dengan metode difusi kertas cakram belum mampu membentuk zona hambat. Isolat aktinomisetes potensial dapat diaplikasikan menggunakan kultur langsung secara in vivo.Abstract The low productivity of agricultural land in Indonesia occurred because of plant diseases attack such as Wilt Fusarium in tomato plant and Basal Stem Rot disease in palm oil caused by Ganoderma boninese. Previous research had successfully isolated the actinomycetes from soil of Arboretum University of Riau However, the antifungal potency of those isolates against Fusarium oxysporum f. sp lycopersici and Ganoderma boninense had not been known. This research aimed to screening 32 actinomycetes isolates against the fungal target by using agar diffusion method. The selected actinomycetes were continued to produce crude antifungal by different duration of fermentation (4, 5 and 6 days) using disc diffusion method. The result of the antifungal activity using agar diffusion method showed that there were 31 isolates that able to inhibit the F. oxysporum f. sp lycopersici and isolate A2.01 showed the highest inhibition zone by 36.10 mm. There were 28 isolates that able to inhibit the G. boninense and isolate D2.28 showed the highest inhibition zone by 45.71 mm. Almost all of the isolate was able to inhibit both of two fungals targets with diffussion agar method, but the crude antifungal compound of the potential isolate by disc diffusion method could not inhibit both of the fungal targets. The potential actinomycetes isolate was suggested to be applied as a culture directly in vivo.

Tanaman budi daya merupakan tanaman yang sering diserang oleh cendawan pathogen, sehingga mengakibatkan penurunan populasi dan produksi tanaman. Pengendalian hayati dengan cendawan antagonis merupakan salah satu metode yang paling efektif dan lebih ramah lingkungan dalam menekan pertumbuhan patogen tanaman. Penelitian ini bertujuan untuk menguji aktivitas antagonis cendawan isolat lokal Riau terhadap beberapa cendawan patogen pada tanaman budi daya. Uji antagonis dilakukan secara in vitro dengan metode dual culture menggunakan lima belas cendawan isolat lokal Riau terhadap Fusarium oxysporum f.sp. lycopersici, Ganoderma philippii, G. boninense, Rigidoporus microporus dan Colletotrichum sansevieria. Hasil penelitian menunjukkan bahwa Trichoderma sp. PNE 4 memiliki aktivitas antagonis tertinggi dan isolat FER C1 serta isolat LLB07 hanya memiliki aktivitas antagonis yang tinggi dalam menekan pertumbuhan cendawan patogen. Trichoderma sp. PNE 4 mampu menghambat pertumbuhan miselium F. oxysporum sebesar 85,30%, G. Philippii (100%), G. boninense (100%), dan C. sansevieria (100%). Isolat FER C1 hanya menghambat R. Microporus (50,39%) dan isolat LLB07 menghambat G. philippii (52,20%). Trichoderma sp. PNE 4 merupakan cendawan uji yang terpilih sebagai cendawan antagonis, karena memiliki kemampuan daya hambat >70%.Abstract Cultivated plants are often attacked by pathogenic fungi resulting in a decline of population and crop production. Biocontrol with antagonistic fungi is one of the most effective and environmentally friendly methods in suppressing the growth of plant pathogens. This study aims to examine the antagonistic activity of local isolates fungi Riau against some pathogenic fungi on cultivated plants. The antagonistic test was performed in vitro by dual culture method using fifteen local isolates fungal Riau against Fusarium oxysporum f.sp. lycopersici, Ganoderma philippii, G. boninense, Rigidoporus microporus and Colletotrichum sansevieria. The results showed that Trichoderma sp. PNE 4 isolate exhibited highest activites and FER C1 and LLB07 isolates exhibited high activities suppressed the growth of the fungal pathogen. Trichoderma sp. PNE 4 isolate inhibited mycelial growth F. oxysporum (85.30%), G. philippii (100%), G. boninense (100%) and C. sansevieria (100%). FER C1 isolate only inhibited R. microporus (50.39%), and LLB07 isolate inhibited G. philippii (52.20%). Trichoderma sp. PNE 4 isolate is test isolates as fungal antagonistic.
