Abstract

This study aims to determine the screening of endophytic bacteria isolatd from Mimosa pudica in Bali Island. This research was conducted from September 2020 to January 2021 at the Plant Disease Laboratory, Faculty of Agriculture, Udayana University, Denpasar. Isolation of endophytic bacteria was carried out by taking a sample of the root of the shy daughter plant which was then washed and dried on a tissue.. Hypersensitivity test followed Klement and Goodman (1967) by growing bacteria in a petri dish containing 100% TSA and NA.Tests were carried out by growing endophytic bacteria in 100% NA and TSA media. Isolation of the roots of the Mimusa pudica plant resulted in 43 isolates. The resulting isolates then passed the hypersensitive test so that 27 isolates were selected. A total of 27 isolates were then tested for hemolysis on blood agar. The final results obtained were 12 endophytic bacterial isolates which were then used in the next practicum. The results showed that the endophytic bacterial isolates were not able to inhibit the fusarium sp. and Phytophthora sp., when using the inhibition percentage formula. This is because the average diameter of the pathogenic fungi colonies in the control treatment (R1) with the average diameter of the pathogenic fungi colonies in the endophytic treatment (R2) has the same size, so that when calculated by the percentage inhibition formula it results in the number 0 which means no. there is a zone of inhibition.

Abstract

The cultivation of catfish using the biofloc system produces waste in the form of remaining ponds that can be used for aquaponic farming systems. The combination of fermentation between catfish waste and chicken manure affects the growth of kale, lettuce, pakcoy, and spinach with an aquaponic system. This research was conducted in the ALC (Agro Learning Center) garden in collaboration with the Master of Agricultural Science Study Program, Postgraduate Program of Warmadewa University. The parameters observed were plant height, number of leaves, fresh weight, and oven dry weight. The best results for plant height are found in spinach plants. The best number of leaves is found in pakcoy plants. As for fresh weight and dry weight the best results were on pakcoy plants. The best concentration of combination of catfish waste fermentation with chicken manure is at a concentration of 1400 ppm.

Abstract

Phosphorus (P) and potassium (K) solubilizing microbes have an important role in accelerating the solubility process of P and K sources which are difficult to dissolve. The purpose of this research was to study the effect of gamma irradiation on the growth rate of P and K solubilizer multifunctional microbes. The microbes used in this study were P and K solubilizer multifunctional bacteria (Staphylococcus pasteuri) and the P and K solubilizer multifunctional fungi (Aspergillus costaricaensis). The microbes were irradiated with gamma rays at a dose of 0; 1; 2.5 kGy. Tests for the rate of bacterial growth were observed through the results of optical density and Total Plate Count (TPC), while fungi were observed through measurement of colony diameter and TPC. Gamma irradiation effects increasing the growth rate of P and K solubilizer multifunctional bacteria (1.0 BPK 5 and 2.5 BPK 5) based on optical density values. At the time of calculating the population using TPC method, the increase in bacterial growth rate tended to be shown by isolates 2.5 BPK 5. The effect of gamma irradiation on the growth rate of fungi was indicated by the colony diameter of the isolate 1.0 BPK 5 which was wider than the wild type isolate or isolate 2.5 BPK 5. TPC results on fungi also showed that gamma irradiation affected the growth rate of fungi at 24, 96, 120, and 288 hours incubation time. Keyword: Gamma irradiation; microbe; growth and fertilizer

Abstract

Processed soybeans such as tempeh and tofu are some of the foods that the people of Indonesia favour. The Tempe and Tofu processing factory produce tofu with the essential soybean ingredients as much as 17 kg every day. The tofu production process starts from soybean immersion, grinding, boiling, filtering, compaction, moulding, cutting, to frying tofu. Production activities from the tofu industry will certainly produce solid and wastewater. These wastes can have a negative impact on the environment. Therefore, the waste must be managed and treated correctly to create an environmentally friendly industry and improve environmental quality. Tofu industry waste management and treatment can be done by identifying the generation of waste that is a priority to be treated and choosing waste treatment technology. There are three alternatives for wastewater treatment from the tofu industry: the chlorine in wastewater, ponds by forming biofilms using biofilter media, and Trickling Filters.

Abstract

Abstract This study aims to determine the effect of biochar dose from urban waste and the concentration of eco-enzymes and their interactions on the growth and yield of shallots. The research was carried out in the greenhouse of the Faculty of Agriculture,Warmadewa University with an altitude of 25 m above sea level, and took place from April to June 2021. This study used a factorial randomized block design method consisting of two factors. The first factor is the dose of biochar with 4 levels (0; 5; 10; and 15 tons ha-1), while the second factor is the concentration of eco-enzyme which consists of 4 treatment levels (0; 7.5; 15.0; and 22.5 ml l-1). The results showed that the interaction between the dose of biochar and the concentration of eco-enzyme had a significant effect on the fresh weight of the stover per clump and had a very significant effect on the dry weight of the stover per clump, but had no significant effect on other variables. The treatment dose of biochar and eco-enzyme had a very significant effect on all observed variables. The results showed that the biochar and eco-enzyme treatments had a very significant effect on all observed variables. The application of biochar and eco-enzyme has a very significant effect on all observed variables. The provision of biochar treatment from urban waste was able to increase the fresh weight of tubers in the 15-ton ha-1 treatment, which was an increase of 39.40% compared to without biochar, while the highest fresh fruit weight was obtained in the eco-enzyme treatment of 22.5 ml l-1, which increased by 29.77% compared without eco-enzyme.

Abstract

This study aims to determine the effect of Gypsum and Etepon on the yield of Siamese orange (Citrus nobilis Var Microcarpa. L) conducted in Belancan Village, Kintamani District, Bangli Regency from December 2020 to July 2021. This study used a randomized block design (RAK) with 2 factors arranged in a factorial manner. The first factor that was tried was the dose of gypsum fertilizer (G) which consisted of 4 levels, namely: G0 (0 g/tree), G1 (250 g/tree), G2 (500 g/tree) and G3 (750 g/tree. While the second factor is the concentration of etepon (E) which consists of 3 levels, namely: E0 (0 ml/l water/tree), E1 (0.75 ml//l water/tree) and E2 (1.5 ml/l water)/tree). Thus, there were 12 combination treatments, each of which was repeated 3 times so that 36 citrus trees were needed. The results showed that the interaction between the dose of gypsum and the concentration of etepon had no significant effect on all observed variables. The highest harvested fruit weight per tree was obtained at a dose of gypsum 750 g/tree which was 6.32 kg or an increase of 70.35% when compared to treatment without gypsum which was only 3.71 kg. The highest harvested fruit weight per tree was obtained in the etepon treatment with a concentration of 1.5 ml/l/tree, which was 6.54 kg, an increase of 51.38% compared to the treatment without etepon, which was only 4.32 kg. Keywords: dose, etepon, gypsum, Siamese orange, yield

Abstract

Brown Planthopper (BPH), Nilaparvata lugens Stal (Hemiptera: Delpachidae) is the important pest of rice. The infestation of BPH reduced the rice yield on rice producer countries in Asia. In Indonesia, the area of BPH infestation frequently fluctuated over the year. BPH directly caused hopper burn and also vector of rice grassy stunt virus (RGSV) and rice ragged stunt virus (RRSV). This study aimed to evaluate the resistance of some rice varieties to different BPH population in Java. Three BPH populations collected from Karawang (West Java), Pekalongan (Central Java) and Kendal (Central Java) were used in this study. The rice resistance was evaluated by conducting honeydew test. There were eight rice varieties tested i.e Sembada 168, Ciherang, Inpari 32, Inpari 33, IR 64, TN1, Ratu Heenati and PTB 33 with five replications. A number of 200 female adults (five females per plot) were starved for 2 hours before inserting to pot containing one seedling. The BPH adults were allowed to feed 40-day-old plants for 48 hours. The area of honeydew excreted by BPH was measured using software Image J. We used analysis of variance (ANOVA) and cluster analysis with ward method and similarity index of Euclidean distance to analyze the rice resistance to BPH. The study indicated three groups of rice resistance level. The variety of Sembada 168 and TN1 were susceptible to BPH. Variety of Ciherang, Inpari 32, Inpari 33 and IR 64 were moderately resistant to BPH. However, PTB 33 and Ratu Heenati were strongly resistant to BPH population of Java.
