Abstract

The long-term presence of synthetic pesticides on agricultural land can lead to a decline in soil fertility. Synthetic pesticides inhibit the activity of essential enzymes in the soil and suppress beneficial microbial populations for plants. One potential approach to mitigate the extent of contamination caused by synthetic pesticides involves the utilization of indigenous pesticide-resistant bacteria. Several upland soil bacteria from Banyumas Regency, Central Java Province, Indonesia, were successfully isolated from a previous study. The isolated bacteria have the potential to be developed as pesticide bio-remediators and biofertilizers. The bacterial isolates are expected to have characters that support plant growth through their ability to provide dissolved phosphate. However, the potential bacterial isolates need to be identified by molecular approaches. This study was conducted to identify bacterial isolates of GT2, SR1, SW1, and PA1 by 16S rDNA sequencing analysis. The results showed that isolate GT2 was placed within a group of reference strains of Bacillus proteolyticus, isolate SR1 was placed within a group of B. paramycoides, isolate SW1 was set within a group of B. albus, and isolate PA1 was placed within a group of Acidovorax delafieldii. The genetic distance of isolate GT2 and B. B. proteolyticus, isolate SR1 and B. paramycoides, isolate SW1 and B. albus were 0.0000 each, and isolate PA1 and A. delafieldii were 0.0061.

Abstract

In order to enhance its competitive position, UD Podang Mas is not solely concentrating on the manufacture of traditional carica preparations, such as cocktails. Instead, it is also diversifying its product range. This diversification includes the development of new products, such as premium cocktails, jams, concentrates, ready-to-drink beverages, and functional powders derived from carica seeds. The development of these product variants is undertaken in order to meet the increasingly diverse market requirements and changing consumer preferences. In light of the aforementioned description, the objectives of this study can be defined as follows: (1) The objective of this study is to analyze the feasibility of a diversified processed carica business at UD Podang Mas Wonosobo Regency based on non-financial aspects, including market and marketing, management and legal, technical, and social and environmental factors. (2) The second objective is to analyze the feasibility of a diversified processed carica business at UD Podang Mas Wonosobo Regency based on financial aspects. The analysis method used in this research consists of a non-financial analysis and a financial analysis. The non-financial aspects include market aspects, technical aspects, management and legal aspects, as well as social and environmental aspects, which are processed descriptively. In contrast, the financial aspect is quantitative data, which includes the assessment of NPV, Net B/C, IRR, and payback period. The results of the non-financial feasibility analysis at UD Podang Mas indicate that the production of processed carica products is a viable undertaking. This conclusion is supported by findings across a range of relevant domains, including market aspects, technical aspects, management and legal aspects, and social and environmental aspects. A financial analysis of six processed carica products produced by UD Podang Mas suggests that these products are economically viable.

Abstract

Weeds are managed by herbicides, but this can reduce the abundance of soil bacteria. This research aimed to determine the effect of active compounds of herbicides on weeds, the abundance of soil bacteria, growth and yield of sweet corn. The experiment was conducted from June to October 2023 in the fields and Laboratory of Agronomy and Horticulture, Universitas Jenderal Soedirman, Purwokerto. A randomized block design was used, consisting of eight treatments and four replications. The treatments included control (H0); weeding (H1); paraquat (H2); glyphosate (H3); paraquat, atrazine, mesotrione (H4); glyphosate, atrazine, mesotrione (H5); paraquat, atrazine, mesotrione, nicosulfuron (H6); and glyphosate, atrazine, mesotrione, nicosulfuron (H7). Results showed that glyphosate and paraquat, were applied before planting, could suppress weeds on sweet corn until 15 days after planting (DAP). Application of atrazine, mesotrione, and nicosulfuron at 21 DAP can increase the success of weed control observed up to 35 DAP of sweet corn. The application of glyphosate, atrazine, and mesotrione showed the highest values for growth variables (plant height, number, and leaf greenness index) and yield variables (fresh weight, diameter, and length of sweet corn cob). Herbicide decrease abundance of soil bacteria on sweet corn field, from 10.07x10-8 CFU/mL to 9.55x10-8 CFU/mL (total bacteria), 9.53x10-8 CFU/mL to 9.52x10-8 CFU/mL (phosphate solubilizing bacteria), 9.90x10-8 CFU/mL to 9.40x10-8 CFU/mL (Rhizobium) and 9.91x10-8 CFU/mL became 9.78x10-8 CFU/mL (nitrogen fixing bacteria). The total density of phosphate-solubilizing bacteria and nitrogen-fixing bacteria in the application of glyphosate, atrazine, and mesotrione (7.78 CFU/g and 9.52 CFU/g) was greater than control (8.77 CFU/g and 8.15 CFU/g).

Abstract

ABSTRACTThe availability of nitrogen in soil is one of the limiting factors to support growth and rice productivity. Nitrogen-fixing bacteria have ability to utilize air nitrogen so it becomes available in the soil. The use of nitrogen-fixing bacteria could potentially reduce application of nitrogen fertilizer. The aim of the experiment was to determine the role of nitrogen-fixing bacteria in reducing inorganic N fertilizer on lowland rice. The research was conducted in April-August 2012 at the plastic house of Babakan Sawah Baru Experimental Station, IPB. The experiment was arranged in randomized block design with two factors, namely nitrogen fertilizer and type of bacteria. The dosage of N fertilizer (urea), i.e. 0, 50, 75 and 100 kg N ha-1. The types of bacteria, i.e. without bacteria, Azotobacter-like, Azospirillum-like, and consortium. The result of the experiment showed that N fertilization significantly affected to all variables except the percentage of empty grains per panicle, 1,000 grain weight, and N content of plant. The types of bacteria significantly affected to root dry weight, number of filled grain per panicle, greenness of leaf, uptake and content of nitrogen (shoot and grain), grain weight per plot. Consortium of bacteria were capable to reduce 25% the use of inorganic N fertilizer from recommendation doses (100 kg N ha-1) that based on the value of agronomic effectiveness.Keywords: Azospirillum-like, Azotobacter-like, consortium of bacteria
