Abstract

Sago starch production leaves solid and liquid wastes that has not been used optimally. Both organic substances still contains a lot of nutrients, and could be processed into raw material for bio-fertilizers media. Solid waste, known as ela sago, has been developed into compost while the liquid waste did not. The objective of this study was to verify volume ratio of liquid inoculant of Azotobacter chroococcum in solid inoculant produced from ela sago; and determine the concentration of sago waste water as a growth medium of biofertilizer A. chroococcum. This study confirms population of A.chroocccum and T. harzianum in ela sago compost reached 106 cfu/g and 108 cfu/g consecutively following enrichment with either 2% or 4% of A. chroococcum liquid inoculant. Sago wastewater can used support A.chroococcum growth. This study proved that waste from sago starch production could be used as a natural medium for biofertilizer.

Abstract

Trichoderma harzianum has been widely known as biological control agents of plant diseases. To obtain inoculum in large quantities waste agricultural products could be used as media. Ela sago is solid wastes originated from sago processing, contains C-organic, nitrogen, phosphorus, potassium, calcium, magnesium, as well as crude protein, fat, crude fiber, ash, cellulose, hemicellulose, lignin, and silica. The objective of this laboatory experiment was to determina the capacity of ela sagu in combination with rice bran and husks as T. harzianum inoculum production. The research was conducted in laboratorium Nemathology, Plant Pathology Agriculture Faculty of Pattimura University. The experiment was conducted from March to April 2014. The medium testedin this experiment were ela sago, ela sago + husk, ela sago + bran, ela sago + husk + bran, husk, bran, husk + bran, and corn. The experiment was set up by using a completely randomized design, replicated three times. The experimental results showed that the number of conidiumon mixed media ela sago + bran and ela sago + bran + husk reached up to 1011 per g media and significantly greater than that of ela sago, elasago + husk, Husk + bran, husk, bran, and corn media.

Abstract

The use of biofertilizers is part of an environmentally friendly plant cultivation. In order to analyze the effect of soaking seeds with several types of biofertilizers on seedling growth and damping off disease in tomatoes, a greenhouse experiment has been carried out using biofertilizers and the fungicide Propineb as control treatment. The biofertilizers used were mixed biofertilizer (BION-UP), Consortium isolates of tomato rhizosphere bacteria (CITRB), consortium of Azotobacter chrococcum and Trichoderma harzianum (Azoto-Tricho). The results showed that soaking tomato seeds in bioagens solution increased plant height, number of petioles, fresh weight and dry weight of plants, as well as suppressed damping off disease in tomato nursery. The CITRB biofertilizer has a better effect on plant growth and diseases suppression than another biofertilizers and Propineb fungicide. CITRB enable to increase plant height by 49.97%, number of petioles by 60.00%, plant fresh weight by 107.23%, dry weight of plants by 129.41%, and suppress damping off disease by 56.67%. BION-UP, CITRB and Azoto-Tricho were able to suppress damping off disease by 22.22%, 27.78% and 16.67% respectively.  The ability of all biofertilizer to suppress damping off disease incidence were better than Propineb fungicide.

Abstract

Seedling fall disease caused by the fungus Rhizoctonia solani is one of the limiting factors in the cultivation of mustard plants. This pathogen can attack plants in the nursery as well as after the plants in the field. The aim of this study was to determine the effect of using biological fertilizers Azoto-Trico and KIBPF with different application time intervals on the development of seedling fall disease and the growth of mustard in the nursery. The study used Azoto-Tricho and KIBPF biological fertilizers with application intervals of 2 days, 4 days and 6 days. The results showed that the application of biological fertilizers Azoto-Tricho and KIBPF with different application time intervals had an effect on controlling seedling fall disease and increasing plant height and plant fresh weight. The application of Azoto-Tricho biofertilizer and KIBPF if applied at intervals of 2 days or 4 days or 6 days had the same ability to control seedling fall disease and increase plant height and fresh weight of mustard plants in nurseries.

Abstract

Upaya peningkatan produktivitas terung seringkali terkendala kerusakan tanaman oleh serangan fitopatogen dan hama. Pemanfaatan metabolit sekunder agens hayati untuk pengendalian fitopatogen dan hama perusak pada tanaman, merupakan cara pengendalian yang ramah lingkungan. Penelitian ini bertujuan untuk mendapatkan konsentrasi metabolit sekunder Trichoderma harzianum yang efektif untuk mengendalikan penyakit busuk buah Phomopsis vexans dan hama perusak daun Epilachna, serta untuk meningkatkan produksi terung. Perlakuan yang dicobakan adalah metabolit sekunder T. harzianum dengan konsentrasi 0%, 10%, 20% dan 30%. Hasil penelitian menunjukkan bahwa perlakuan metabolit sekunder T. harzianum menekan penyakit busuk buah Phomopsis, tetapi tidak berpengaruh terhadap kerusakan daun Epilachna. Pengobatan dengan konsentrasi 10%, 20% dan 30% masing-masing dapat menurunkan intensitas penyakit 51.65%, 64.25% dan 69.63%. Kerusakan daun oleh Epilachna sp tergolong ringan untuk semua tingkat konsentrasi yakni berkisar 3.65-4.32%. Perlakuan metabolit sekunder T. harzianum dengan berbagai tingkat konsentrasi berpengaruh terhadap panjang buah tetapi terhadap jumlah buah, diameter buah, dan berat buah tidak berpengaruh
