Abstract

Wilayah Kabupaten Banyumas mempunyai kisaran kondisi klimat beragam, mengikuti kisaran ketinggian tempat yang cukup luas serta tersedianya beragam jenis tumbuhan penghasil komponen lignoselulosa sebagai substrat berbagai jenis jamur lignoselulosik. Kondisi tersebut mendukung diperolehnya keragaman jenis jamur termasuk jamur kuping indigenous yang perlu dieksplorasi untuk berbagai kepentingan, termasuk untuk mendukung upaya pengembangan produksinya. Penelitian yang dilaksanakan dengan metode survei ini secara umum mendapatkan ada 2 (dua) macam isolat jamur kuping dengan ciri morfologi tubuh buah yaitu berwarna merah coklat tua dan merah coklat muda dengan tekstur yang relatip sama yaitu berlendir tetapi dengan kecepatan pertumbuhan koloni miselia dan kualitas pertumbuhan miselia yang berbeda. Jamur kuping dengan warna tubuh buah merah coklat tua pada umumnya pertumbuhan miselianya lebih baik daripada jamur kuping dengan warna tubuh muah merah coklat muda.

Abstract

The aim of this study was to find out the effect of neem leaf extract (Azadirachta indica A. Juss.) on the growth medium of tomato plant toward fusarial wilt and to determine effective concentration and time of application of the extract to control the wilt. Experiments arranged in a Completely Randomized Design (CRD) was employed for in vitro antimicrobial assay and in a Randomized Complete Block Design (RCBD) for in planta antimicrobial assay, both of which were to find out the inhibitory effect of the extract on colony growth of Fusarium oxysporum (Schlecht). f.sp. lycopersici (Sacc.) Snyd. et Hans. (Fol).  The results indicated that neem leaf extract concentration of 5% applied at 7 DAP (Day After Planting) was the most effective treatment in inhibiting disease intensity of fusarial wilt on tomato plant showing inhibitory effect of up to 89.32%.

Abstract

Pleurotus ostreatus cultivation is performed using solid medium to harvest fruit body and using liquid medium to harvest mycelia in submerged culture. Modifying nutrients in the medium to increase protein content of the fruitbody and mycelia can be done through addition of nitrogen-containing materials. This study aims to determine: the appropriate composition of the liquid medium for high mycelial growth and protein content; and the exact composition of the solid medium to obtain high fruitbody product and protein content. The method was experimental with completely randomized design (CRD). The treatments were incubation of P. ostreatus on three types of liquid medium and four types of solid medium. The results showed that the optimal liquid medium composition for mycelial growth was Liquid Fermentation Medium 1 (FC1) with 10% corn fluor, and the highest protein content was in Liquid Fermentation Medium 2 (FC2 = 29.76%). While the optimal solid medium composition for fruitbody production was the medium with 3% corn starch supplement (TJ3), and the highest protein content was obtained from the medium without corn starch supplement (TJ0=24.69%). The increase of mycelial and fruitbody weight from the medium with the addition of corn material indicated a prospective in cultivation process, however effort to increase protein content of the fruit body needs further research. Cultivating P. ostreatus in mycelial phase may take shorter incubation time, may be produced in mass production with less space consuming, and higher protein content than that by producing fruitbody.

Abstract

Pleurotus ostreatus is a common mushroom cultivated in Indonesia, and potential properties of bioactive compounds for medicinal mushroom. This study was aimed at obtaining P.ostreatus extract bioactive compounds potential in inhibiting the proliferation of cervical cancer cells (HeLa) and evaluating the HeLa cell proliferation kinetics and HeLa cell death mechanisms. The research was beneficial in making this product can be easily applied in a more controlled industrial scale. Anticancer activity test through a cytotoxic test using the MTT [3- (4,5-dimetiltiazol-2-yl) -2.5-diphenyl tertrazolium bromide], the kinetics proliferation of HeLa cells and HeLa cell death mechanism was performed. Linear regression analysis was used to analyze the data. Ethyl acetate extract of P. ostreatus isolated from Madiun showed the best results with IC 50 = 107.59 g / ml. HeLa cell proliferation kinetics analysis showed that the application of bioactive compounds 100 g / ml resulted in an increase of in death of HeLa cells along with length of incubation time. An important finding was that HeLa cells death by apoptosis was greater than by necrosis. In conclusion, the extracts of P. ostreatus has the potential to inhibit the growth of HeLa cells.
