Abstract

 The purpose of this research is to understand the effect and the best dossage of bromelain wastes solid compost for vegetative growth of chilli plants. Accumulation of pineapple wastes made by the large pineapple plantation area. The litter of pineapple bromelain enzyme (bromelain wastes) still containing organic matter that could composted for plant nutrition. The composting of it can be accelerated by induction inoculum of cellulotic Aspergillus sp. fungus. The research used Completely Randomized Design method with seven treatment and three replications. The treatment used two different type of compost. The composition of compost A type is:  0,5 kg bromelain + 0,5 kg leaves litter + 0,5 kg livestock wastes + inoculum 1%. The composition of compost B type is:  1 kg bromelain + 0,5 kg livestock wastes + inoculum 1%. The treatment conducted P0:  5 kg soil (control). P1:  5 kg soil + 1,4% A type compost. P2: 5 kg soil + 1,7% A type compost. P3: 5 kg soil + 2% A type compost. P4: 5 kg soil + 1,4% B type compost. P5: 5 kg soil + 1,7 % B type compost. P6: 5 kg soil + 2% B type compost. Variance analyzed of obtained data were using ANOVA and tested using the Least Significant Difference Test (LSD) method. Parameter of this study are number of leaves and chlorophyll content. The results showed that the application of P6: 2% dossage B type compost from bromelain solid compost could optimized the vegetative growth of chili plants (Capsicum annuum L.). Key words: Aspergillus sp.; bromelain; chili; compost.

Abstract

DHF (Dengue Hemorrhagic Fever) is a serious problem in Indonesia. DHF disease control has been applied so far, one of which is the use of larvacide temephos (abate). However larvacide is a chemical insecticide that has a negative impact on human health and causes resistance. Therefore in this research, biological control is carried out by utilizing entomopathogenic fungi as a larvacide. The purpose of this study was to determine the effectiveness of entomopathogenic fungi isolated from Ae aegypti larvae. Against the death of Ae. Aegypti mosquito larvae with the moist chamber method. This study used a completely randomized design (CRD) with a factorial pattern and performed two repetitions. Factor A is a type of fungi with 3 levels, namely A1: Aspergillus sp1, A2: Aspergillus sp2, and A3: Syncephalastrum sp. Factor B is a dilution with 7 levels, namely B0: Control, B1: 100 (without dilution), B2: 10-1, B3: 10-2, B4: 10-3, B5: 10-4, B6: 10-5 with every treatment was applied in 2 repetitions. Observations were made 24 hours after treatment for 3 days. Data were analyzed using analysis of variances (anova) and continued with the Least Significant Difference Test (LSD) at 5%. The results indicate that fungi isolates are the most effective in killing Ae. Aegypti mosquito larvae is Aspergillus sp1 and Aspergillus sp2 on the treatment of spores without dilution. Key words: DHF; larvacide; Aedes aegypti; Entomopathogenic Fungi.

Abstract

The growth of a plant is influenced by the availability of nutrients. To meet these nutritional needs, chemical fertilizers are still widely used. In addition to nutritional needs, the growth of a plant is also influenced by pathogenic microorganisms that cause disease. The emergence of diseases in plants causes chemical pesticides to be increasingly used. The continuous use of chemical fertilizers and chemical pesticides can make living organisms susceptible to high toxicity of chemical compounds. In addition, the impact has an impact on improper management of agricultural waste as well as polluting the environment when it has been burned or discharged into water bodies. One alternative to overcome these problems is the application of biological control using Trichoderma spp. Trichoderma spp inoculum application can significantly regulate the rate of plant growth and suppress the growth of plant pathogenic microorganisms. Trichoderma spp. including plant growth promoting microbes that have the ability to colonize plant roots so as to provide benefits to their host, modulate phytohormonal production, increase soil nutrient availability, stimulate plant growth and tolerance to biotic and abiotic stresses, and resistance to pathogens. Inoculum of Trichoderma spp. can be applied to plants through seeds, leaves, roots of seedlings, and soil. Based on literature review, it is known that the application of Trichoderma spp. inoculum showed a significant effect on plant growth and suppress the growth of pathogenic microorganisms.Key words: Trichoderma spp.; inoculum; fungi; biofertilizer; biofungicide.

Abstract

As one of the horticultural plants that has important economic value, the cultivation of red chili (Capsicum annuum L.) is often constrained by the attack of Fusarium sp., which can cause losses due to decreased production. Induction of the magnetic field on the plant is known to be able to increase growth, development, and production in various plants.  In this research, we studied the production of chili grown from seeds exposed to a 0.2 mT magnetic field and then infected with Fusarium sp. The study was conducted factorial using a completely randomized design with 2 factors. The first factor is the exposure of a 0.2 mT magnetic field to the seeds consisting of controls, without exposure to a magnetic field (M0), magnetic field exposure for 7 minutes 48 seconds (M7), and 15 minutes 30 seconds (M15). The second factor is Fusarium sp. infection on seeds that have been exposed to a magnetic field for 60 minutes by immersion of the seeds with spore suspension of Fusarium sp. with the density of 1 x 107 conidia/ml (F60), and without Fusarium sp. infection (F0). Each treatment unit was repeated 5 times. The data obtained were analyzed for variance at α = 5% followed by the least significant difference test using the Fishers Test at α = 5%. The results of data analysis showed that the interaction of 0,2 mT magnetic field exposure and infection of Fusarium sp. in chili seeds significantly affect the stomata index, the fruiting rate, and the number of fruit but do not affect the content of total chlorophyll, carbohydrate, as well as the number of flowers. The highest fruiting rate and number of fruits obtained from the treatment result of 0.2 mT magnetic field exposure for 15 minutes 36 seconds without Fusarium sp. infection (M15F0). Infection of Fusarium sp. in these seeds (M15F60) reduce the fruiting rate and the number of fruit but it is not significant and even almost similar with the fruiting rate and the fruit number of the plant growth from control treatment (M0F60).   Key words: magnetic field, Fusariumsp., seed, and production.
