Abstract

Antagonistic Test of Indole Acetic Acid Producing Bacteria Against Helminthosporium maydis In Vitro Helminthosporium maydis is the cause of important diseases in maize, including leaf blight. Leaf blight is the most dominant disease because it causes large losses. The use of biological agents is one way to treat leaf blight that is environmentally friendly. One of these biological agents is IAA-producing bacteria. This research was conducted in vitro. The results showed that there were several IAA-producing bacteria that were able to inhibit the growth of H. maydis in vitro with the highest inhibition in the treatment of B. thuringiensis GR12 isolates of 96.44% when compared to controls. IAA-producing bacteria were able to inhibit the growth of H. maydis biomass with the percentage of inhibition ranging from 73.97% - 80.82%. The treatment of IAA-producing bacterial filtrate at a concentration of 20%-90% was able to inhibit the growth of H. maydis colonies in vitro. The results of this study indicate that IAA compounds produced by bacteria are antifungal.

Abstract

The Relationship between Soil Organic Matter Levels with Diversity of Soil Macrofauna on Agricultural Land in Baturiti District This study aims to determine the level of soil macrofauna diversity on agricultural land in Baturiti District and to determine the relationship between soil organic matter levels and soil macrofauna diversity on agricultural land in Baturiti District. Sampling locations were taken on two types of land use, two organic land cultivation systems at an altitude of 903-1259 meters above sea level and conventional land at an altitude of 925-1173 meters above sea level. The method in this study is the sampling method, taking soil macrofauna and soil organic matter by direct observation to the research location at the sampling point, namely 5 types of organic agricultural plants and 5 types of conventional agricultural plants which are considered representative of the presence of soil macrofauna and represent each type of plant in the study area. Soil macrofauna sampling was carried out using 2 methods, namely pit fall trap, quadratic method and hand sorting. Sampling of organic matter was carried out by hand sorting method, on organic and conventional land in Baturiti District. Soil macrofauna found in organic and conventional land were identified and calculated values: Diversity index (H'), Abundance index (R1), Dominance (C). Soil from organic and conventional land was analyzed for organic matter content (C). The data obtained were analyzed by hypothesis testing (t) using the SPSS application to determine the relationship between soil organic matter content and soil macrofauna. The results of this study indicate that the level of soil macrofauna diversity on organic land with an altitude of 903-1259 mdpl is in the medium category (1.493- 2.421) and the level of soil macrofauna diversity on conventional land with an altitude of 962- 1318 mdpl is in the medium category (1.011- 1,961). On organic land with an altitude of 903- 1259 mdpl and conventional land with an altitude of 962 mdpl and 1173 mdpl, there is no relationship between soil organic matter content and macrofauna diversity. Based on the results of the hypothesis test, it was shown that it was rejected. On conventional land with an altitude of 1318 meters above sea level, there is a relationship between soil organic matter content and macrofauna diversity. Based on the results of the hypothesis test, it shows that it is accepted.

Abstract

Spatial Analysis of the Potential and Status of Soil Damage in Sawan District, Buleleng Regency This study aims to determine the potential and distribution of soil damage status in Sawan District, Buleleng Regency. The research method used is a survey method and a qualitative method of spatial analysis. Based on the results of overlaying land use maps, slope maps, rainfall maps and soil types maps, there are 7 homogeneous land units. The land was taken from homogeneous land units of existing land use, namely natural forests, mixed gardens, settlements and rice fields. After the soil sample was taken, it was continued with soil analysis in the laboratory to determine the bulk density, total porosity, degree of water release, pH, fraction composition, electrical conductivity and number of microbes. The results showed that Sawan District had low soil damage potential at the locations of homogeneous land units I, II, III, and IV and moderate soil damage potential at homogeneous land units V, VI, and VII locations. The status of soil damage in Sawan District is lightly damaged. The parameter causing the damage status in the research area is the water release degree parameter. These parameters get a relative frequency value of 100% with a score of 4 (four). The direction of controlling the status of soil damage that can be done is by providing organic matter and good soil management efforts.

Abstract

Evaluation of Rice Field Fertility Status Based on Geographical Information System in Negara District, Jembrana Regency Lowland rice production at Negara District in 2014 was 6.89 tons/ha and in 2015 decreased to 6.67 tons/ha. This is thought to be due to the reduced ability of the land to support the agricultural production process. The purpose of this study was to determine the status of soil fertility and the parameters of the limiting factors of soil fertility, to make a map of the status of soil fertility, and to provide direction for the management of soil fertility. This research was conducted from December 2021 – March 2022. The methods used in this study included survey and soil test methods with parameters of fertility status including CEC; BS; organic C; total P and total K. The results showed two soil fertility statuses in the study area, namely low in HLU I (Pengembengan Village, West Tegal Badeng, East Badeng Tegal, Baluk, Banyubiru, Kaliakah, Lelateng, Bale Agung Baler) and HLU II (Pengambengan Village, East Tegal Badeng, Banyubiru, Lelateng) and moderate soil fertility in HLU III (Kaliakah Village, Berangbang, Bale Agung Baler) and HLU IV (Kaliakah Village, Berangbang, Bale Agung Village). The limiting factors for soil fertility status were CEC and moderate K2O content and low organic C content. The direction of soil fertility management is the addition of organic matter and K fertilizer to improve soil fertility status.

Abstract

Soaking Gerbera Cut Flowers (Gerbera jamesonii) in a Mix of Coconut Water Solution and Wuluh Starfruit Extract to Extend Vase Life Gerbera is a flowering ornamental plant that is used as cut flowers and has high economic and aesthetic value. Gerbera flowers are often damaged such as wilting, easily broken stems, broken buds and flower discoloration. The very short shelf life of cut gerbera flowers requires proper postharvest handling to maintain freshness. This research aims to determine the effect of coconut water (Cocos nucifera) and wuluh starfruit (Averrhoa bilimbi) extract and its interaction in increasing vase life and to determine the best soaking solution dose for gerbera cut flowers. The research used a Completely Randomized Design consisting of two factors, that is coconut water with doses of K1: 40 ml, K2: 60 ml, and K3: 80 ml, and wuluh starfruit extract with doses of B1: 10 ml, B2: 20 ml, and B3: 30 ml, there were 9 treatment combinations and each treatment was repeated three times. The results showed that the interaction between coconut water and wuluh starfruit extract had a significant effect on the solution acidity and vase life variables. Treatment of 80 ml coconut water + 10 ml star fruit extract (K3B1) was able to maintain the appearance of gerbera cut flowers in a vase up to 13,83 days.
