Abstract

Pyrene degradation and biosurfactant activity by a new strain identified as Gordonia cholesterolivorans AMP 10 were studied. The strain grew well and produced effective biosurfactants in the presence of glucose, sucrose, and crude oil. The biosurfactants production was detected by the decreased surface tension of the medium and emulsification activity. Analysis of microbial growth parameters showed that AMP10 grew best at 50gmL-1pyrene concentration, leading to 96% degradation of pyrene within 7days. The result of nested PCR analysis revealed that this isolate possessed the nahAc gene which encodes dioxygenase enzyme for initial degradation of Polycyclic Aromatic Hydrocarbon (PAH). Observation of both tensio-active and emulsifying activities indicated that biosurfactants which produced by AMP 10 when grown on glucose could lower the surface tension of medium from 71.3 mN/m to 24.7 mN/m and formed a stable emulsion in used lubricant oil with an emulsificationindex (E24) of 74%. According to the results, it is suggested that the bacterial isolates G. cholesterolivorans AMP10 are suitable candidates for bioremediation of PAH-contaminated environments.How to CiteKurniati, T.

Abstract

Purwodadi Botanical Garden has more than one hundred collection of cultivated bananas. The major problem in keeping their existency is  the occuring of  Fusarium wilt disease  which was commonly controlled by pesticide or eradication to terminate the infectious cycles. Trichoderma and Gliocladium were frequently used as antagonist fungus in controlling the Fusarium wilt disease in kenaf, tomato or  the other plants. So,  this study aims was to know the  potency of Trichoderma and Gliocladium on Fusarium growth inhibition. The experimental design was done by Randomized Complete Design Factorial using three factors i.e. antagonist fungus, Fusarium and growth distance. The level of retardation was measured by the growth distance of Fusarium  that interacted to antagonist fungus and data analysis were conducted  by Analysis of Variance (ANOVA). The results showed that Trichoderma has higher inhibition than Gliocladium and the highest inhibition occurred at 1 cm  distance of inoculum which was performed on Fusarium 4 (77.78%). There was not any significant differencies between Fusarium 1 with Trichoderma (73.55%) and Fusarium 2 with Gliocladium (73.33%). At 2 cm distance, the highest inhibition occurred in Fusarium 3 by Trichoderma (72.71%), which  was not significantly different with Fusarium 1, 2 and 4. While at 3 cm distance, the highest inhibition on Fusarium 4 by Trichoderma  was 51.11% and not significantly different from Fusarium 1, 2 and 3.

Abstract

Abstrak Tujuan dari penelitian ini adalah mengetahui toksisitas Bacillus thuringiensis isolat Madura terhadap berbagai instar larva nyamuk Aedes aegypti dan pengaruh toksin yang dihasilkan oleh                         B. thuringiensis isolat Madura terhadap struktur epitel dan jaringan usus larva nyamuk A. aegypti. Penelitian dilakukan dengan menggunakan rancangan percobaan faktorial, dengan kombinasi perlakuan ditempatkan menurut RAK dan diulang 3 kali. Setelah rearing larva nyamuk, dilanjutkan dengan pembuatan suspensi bakteri dengan seri pengenceran 100–10-5. Jumlah bakteri dihitung, diikuti perhitungan jumlah spora bakteri dengan metode TVSC, kemudian dilanjutkan uji toksisitas bakteri terhadap berbagai instar larva nyamuk. Setelah 24 jam kemudian dihitung jumlah larva yang mati. Tingkat kerusakan yang ditimbulkan oleh bakteri dilihat dengan cara dibuat irisan melintang larva nyamuk dengan metode parafin. Hasil penelitian menunjukkan bahwa toksisitas bakteri B. thuringiensis isolat Madura dalam membunuh larva nyamuk instar I sampai 88,89%. Toksisitas yang tinggi tersebut terdapat pada kepadatan bakteri sebanyak 1,51x108 selml-1, tetapi untuk kepadatan bakteri di bawahnya kurang efektif dalam membunuh larva nyamuk Aedes aegypti. Pada kepadatan bakteri tertinggi, semakin tua umur stadium larva nyamuk maka semakin resisten terhadap terhadap serangan toksin yang dihasilkan oleh bakteri B. thuringiensis isolat Madura. Nilai LC50-24 jam untuk instar I sebesar 8,08x107 selml-1, instar II sebesar 9,09x107 selml-1, instar III sebesar 3,94x108 selml-1 dan instar IV sebesar 2,66x108 selml-1. Pengaruh kristal toksin B. thuringiensis isolat Madura terhadap struktur epitel dan jaringan usus tampak pada jaringan usus yang tidak utuh dan inti sel epitel hancur serta bagian dalam usus berlubang-lubang, sedangkan bagian luarnya berwarna hitam. Kata kunci: Aedes aegypti, Bacillus thuringiensis, musuh alami, pemberantasan     Abstract The aim of this study is to investigate toxicity of Bacillus thuringiensis which is isolated from Madura Island as natural enemy of Aedes aegypti larvae. The larvae of Aedes aegypti were reared to provide F2 generation in the laboratory. Larvae selection was carried out by exposing the first, second, third and fourth instar larvae of Aedes aegypti  (15 larvae in each dilution) for 24 hour to each concentration of Bacillus thuringiensis was isolated from Madura island which had been determined LC50-24 h to cause about 50% larvae mortality. Number of bacteria spora is known with TVSC method. Cross section of larvae is made with paraffin method to know level of destruction due to bacteria. The result of the study indicated that Bacillus thuringiensis  isolated from Madura Island able to  kill first instar of Aedes aegypti larvae until 88,89%. High toxicity of bacteria in the density of bacteria cell is 1,51x108 cellml-1. The bacteria cell density less than 1,51x108 cellml-1 not effective. In the highest density, the older stadium of larvae more resistance than the younger stadium larvae. Average of LC50-24 h for first instar larvae is 8,08x107 cellml-1, second instar is 9,09x107 cellml-1, third instar is 3,94x108 cellml-1 and fourth instar is 2,66x108 cellml-1. The toxin’s of Bacillus thuringiensis effects affect structure of epitel and intestine tissue of Aedes aegypti larvae are not complete. This phenomena indicates that Bacillus thuringiensis from Madura Island have its potential to become biocontrol of Aedes aegypti. Keywords: Aedes aegypti, Bacillus thuringiensis, biocontrol, natural enemy

Abstract

Virgin Coconut Oil (VCO) merupakan minyak yang dihasilkan dari buah kelapa tanpa melalui proses pemanasan, pemurnian, atau penambahan bahan kimia. Kelurahan Jatiayu Yogyakarta merupakan daerah dekat pantai selatan Pulau Jawa yang memiliki banyak pohon kelapa maka daerah tersebut merupakan daerah yang ideal untuk sasaran sosialisasi pembuatan VCO. Metode yang digunakan adalah strategi partisipasi aktif dengan keterlibatan peserta. VCO dibuat dengan cara fermentasi sederhana menggunakan air kelapa sebagai starter. Rangkaian kegiatan yang dilakukan meliputi pretest, pemberian materi, demonstrasi pembuatan VCO, dan posttest. Hasil pretest menunjukkan bahwa 100% peserta belum mengetahui tentang VCO. Namun, berdasarkan hasil posttest diketahui 88% peserta telah memahami tentang pembuatan VCO hal ini menandakan terjadi peningkatan pengetahuan dan keterampilan peserta tentang pengertian dan cara pembuatan VCO sehingga kegiatan yang telah dilaksanakan telah memberikan manfaat bagi peserta. Peserta pelatihan mampu menghasilkan sekitar 800 mL VCO diakhir kegiatan. Virgin Coconut Oil (VCO) is oil produced from coconuts without going through a process of heating, refining, or adding synthetic chemicals. This oil has many health benefits including being anti-microbial, maintaining heart health, facilitating the digestive process, and maintaining healthy skin and hair. Considering that Kelurahan Jatiayu Yogyakarta is an area near the south coast of Java Island which has lots of coconut trees, this area is an ideal area for the socialization target of VCO production. The method used is an active participation strategy with the involvement of participants. VCO is made by simple fermentation using coconut water as a starter. The series of activities carried out included a pretest, giving material, demonstrating the manufacture of VCO, and posttest. The pretest results showed that 100% of the participants did not know about VCO. Based on the results of the posttest, it was found that 88% of the participants had understood about making VCO and were able to produce around 800 mL of VCO. There was an increase in the knowledge and skills of the participants regarding the meaning and method of making VCO so that the activities that had been carried out provided benefits for the participants.
