Penggunaan Limbah Medium Tanam Jamur Tiram (Pleurotus Ostreatus) Dalam Penyerapan Warna Limbah Cair Batik

Medium tanam budidaya jamur tiram (Pleurotus ostreatus) yang telah termanfaatkan akan menimbulkan limbah baru. Permasalahan limbah yang tidak dapat dihindarkan karena setelah pemanenan, medium tanam jamur (baglog) selalu dibuang sebagai limbah karena tidak mampu ditumbuhi jamur tiram lagi. Pemanfaatan limbah medium yang selama ini telah dilakukan dianggap kurang efektif. Pemanfaatan lain yang sedang dikembangkan adalah sebagai agen dekolorisasi limbah cair batik. Limbah baglog masih mengandung miselium P. ostreatus dan selulosa yang berperan sebagai penyerap pewarna. Penelitian ini bertujuan untuk mengetahui kemampuan limbah medium tanam P. ostreatus pada proses penyerapan warna limbah batik, serta kombinasi rasio berat limbah medium : volume limbah batik dan waktu inkubasi manakah yang mampu menyerap warna limbah batik secara optimum. Metode yang digunakan dalam penelitian ini adalah metode eksperimental dengan rancangan percobaan berupa Rancangan Acak Lengkap (RAL). Hasilnya menunjukkan bahwa limbah medium tanam P. ostreatus mampu menyerap warna limbah cair batik serta kombinasi rasio berat limbah medium : volume limbah batik 1:2 dan waktu inkubasi 72 jam yang mampu menyerap warna limbah batik secara optimum

Pengaruh Inokulasi Mikoriza Vesikula Arbuskula (Mva) Campuran Terhadap Kemunculan Penyakit Layu Fusarium Pada Tanaman Tomat (Solanum Lycopersicum)

Tomato has an important role to fullfil the nutrition of society. The most important problem in the cultivation of tomatoes is fusarium wilt caused by Fusarium oxysporum it will attacking the plants from nursery to adult. One of the alternative control is use the Vesicles Arbuscular Mycorrhizae (VAM). The success of VAM infection in plants is determined by the dose and the inoculation. The aim of this research is to determine the effect of dose and mixture VAM inoculation to against the emergence of fusarium wilt in tomato plants and to determine the dosage mixture VAM inoculation as the most effective way for controlling fusarium wilt in tomato plants. The method of this research used experimental with completely randomized design. The experimental treatment consists of two types of treatment that are combined with used 5 doses of VAM mixture (0 g/plant, 10 g/plant, 12,5 g/plant, 15 g/plant, 17,5 g/plant) and used two ways of inoculation ( inoculation when the seed is planted and inoculation when transplanting the seeds). Each treatment was repeated 3 times and each test are three plants. The parameters was observed the incubation period of the disease and the intensity of fusarium wilt as the main parameter and the measurement of pH, temperature, humidity room, and the degree of infection as supporting parameters. The results of this research showed that the dosage and inoculation of VAM mixture is not able to reduce the emergence of fusarium wilt on tomatoes, but it was able to extend the incubation period of fusarium wilt on tomato plants a dose with 10 g /plant inoculated plants when the seeds are planted and inoculation when transplanting the seeds

Pengaruh Perendaman Etil Metan Sulfonat (Ems) Terhadap Daya Tahan Tanaman Kecipir Psophocarpus Tetragonolobus (L.) Dc Polong Pendek Dari Serangan Patogen Rhizoctonia Solani

Induced Mutations with EMS (Ethyl Methane Sulfonate) has been widely reported to increase genetic diversity and improve quality of the crop. This study aimed to find out the effect of EMS immersion on short pod winged bean plant (Psophocarpus tetragonolobus (L.) DC) resistance from Rhizoctonia solani pathogens attack and to determine the optimum concentration to obtain mutan plants which resistant to R. solani pathogen attack. The method was experimental with Completely Randomized Design (CRD). Variables used were 2, i.e. independent and dependent variables. The independent variable was 4 levels of EMS concentrations (E0 = no EMS, E1 = 0,1% EMS, E2 = 0,3% EMS and E3 = EMS 0,5 %) and the dependent variable was the resistance of plants against disease intensity caused by R. solani. Observed parameters were dumping-off disease intensity caused by R. solani. The experiment was replicated 6 times. Data were analyzed using F test with confident levels of 5% and 1%. Furthermore, LSD (Least Significant Difference) test were carried out to determine the differences of each treatment. The results indicated that EMS caused the short pods winged bean plants more vulnerable against the attack of R. solani. Mutants categories obtained in the three treatments of EMS concentrations. Mutants were found in E1, E2 and E3 treatments in the intensity of dumping-off disease of R. solani pathogens in categories 1 and 4; 4; 3 and 4, respectively
