Abstract

Propoxur is a non-systemic carbamate insecticide that is widely used in Indonesia to control insect pests. However, its persistence and toxicity pose environmental concerns. Bioremediation with bacteria is a viable method for mitigating the detrimental effects of propoxur residues. The goal of this work was to isolate and characterize bacterial strains that can degrade propoxur. Isolation by enrichment culture procedures, utilizing propoxur as the sole carbon source. The isolates' morphological and physiological features were examined, and their degradation potential was determined. Six bacterial samples were isolated from a pineapple plantation in Lampung, Indonesia, and one strain, known as LED 6, showed great potential for propoxur breakdown. Molecular identification with 16S rRNA gene sequencing identified the isolate as Brucella pseudintermedia. Growth characterisation revealed that the isolate performed best at 28 °C and pH 7. After 72 hours of incubation with 500 ppm propoxur, LED 6 had deteriorated around 26% of the starting concentration. Keywords: bioremediation, Brucella pseudintermedia, pineapple, propoxur

Abstract

Controlling plant pests and diseases (PPD), such as the thorny amaranth weed (Amaranthus spinosus L.), is crucial to ensuring optimal plant growth and development. One option for weed control is to use organic pesticides manufactured from liquid smoke extracted from red fruit (Pandanus conoideus) seed waste. The goal of this research was to identify phenolic metabolite compounds present in liquid smoke from red fruit seed waste, analyze their effects on the germination of thorny amaranth seeds, and determine the most effective dose for minimizing weed germination. Phenolic chemicals were evaluated using GC-MS (gas chromatograph-mass spectrometer), and seed viability and vigor were assessed with liquid smoke doses of 0 mL/seed (B0), 0.1 mL/seed (B1), 0.2 mL/seed (B2), 0.3 mL/seed (B3), and 0.4 mL/seed (B4), with three replications each. The criteria assessed were phenolic chemical types, germination rate, growth potential, germination rate index, vigor index, uniformity of growth, and growth rate. The study discovered eight different types of phenolic compounds in the liquid smoke from red fruit seed waste. Liquid smoke had a significant effect on the germination and growth rates of thorny amaranth seeds, with the 0.4 mL/seed dose being the most effective at inhibiting germination, which was reduced to 0.71%. Keywords: liquid smoke, red fruit seeds, thorny spinach, viability, vigor

Abstract

Sweet corn straw has nutritional value comparable to wheat and has the potential to be used as animal feed; however, its high crude fiber concentration reduces digestion. The purpose of this study was to assess nine lactic acid bacteria (LAB) isolates from cocoa fermentation (H 0.3, H 0.13, H 0.17, H 0.24, H 0.26, H 1.22, H 2.34, H 3.1, and H 3.3) as inoculants in silage production from corn straw. LAB identification was done using CaCO₃-clear zone tests, morphological examination, and catalase testing. Isolates H 0.13 and H 2.34 performed the best, as evidenced by low pH, significant lactic acid generation, and reduced water-soluble carbohydrates. Based on 16S rRNA gene sequencing, both were identified as Lactiplantibacillus species. Silage showed good qualities, both with and without inoculants: slightly fine to moderately coarse texture, yellowish-green hue, and sour scent. Minor fungal growth was seen in inoculated samples. The nutritional content met the Indonesian National Standard (SNI) for cow feed, with low crude fiber (13.11−13.58%) and ash level (2.72−3.36%). Fermentation quality was judged "very good," with a Fleigh value higher than 85. Finally, Lactiplantibacillus isolates H 0.13 and H 2.34 work well as inoculants for sweet corn straw silage, enhancing its nutritional and fermentative quality. Keywords: corn straw, lactic acid bacteria, silage

Abstract

Kaur Regency is a high-potential vannamei shrimp (Litopenaeus vannamei) aquaculture area in Bengkulu Province that frequently experiences high mortality rates due to vibriosis caused by pathogenic Vibrio spp. The high shrimp mortality rates resulting in decreased production or crop failure due to attacks or infections of vibriosis disease. Data on these Vibrio spp. in traditional Kaur ponds is required for illness prevention. To identify pathogenic Vibrio spp., this study included purposeful sampling and testing, as well as data analysis. Seven Gram-negative isolates (OALF 1, 2, 3, and 5 from shrimp organs; WALF 7, 8, and 10 from pond water) produced green/yellow colonies on TCBSA medium. Biochemical tests (Gram KOH 3%, catalase, oxidase, fermentation (O/F), TSIA, MIO, lysine decarboxylase, gelatin, Simon citrate, methyl red, urease, glucose, maltose, lactose, mannitol, and sorbitol) revealed that OALF isolates from vannamei shrimp organs have morphological and physiological similarities to the pathogenic species Vibrio parahaemolyticus, whereas WALF isolates from pond water are similar to the pathogenic species V. pluvialis. The study identified Vibrio spp. as the cause of vibriosis in L. vannamei in traditional Kaur ponds, emphasizing the need for improved water and feed management, as well as proper pond environmental practices, potentially including probiotics derived from healthy local shrimp digestive bacteria, to reduce losses in vaname aquaculture in Kaur Regency, Bengkulu. Keywords: Litopenaeus vannamei, pathogen, traditional ponds, Vibrio, vibriosis

Abstract

The purpose of this study is to increase the propagation success rate of Rosa centifolia L. cuttings by examining the interaction of several types of growing media with varying amounts of auxin-based plant growth regulators. A factorial Completely Randomized Design with four treatment groups and three replications. The first factor was the composition of the planting media, which was made up of four tiers of soil: soil:husk (1:1), soil:compost (1:1), and soil:manure (1:1). The second factor was the concentration of indole-3-butyric acid (IBA), which has four levels: Z1 (control), Z2 (500 ppm), Z3 (1000 ppm), and Z4 (1500 ppm). The acquired data were subjected to Analysis of Variance, which was followed by a comparison using the Least Significant Difference test to identify significant treatment effects. The results showed that the soil:compost (1:1) treatment was the most effective planting media composition in terms of shoot length, number of leaves, and flowering time. Providing auxin concentrations is not effective in increasing root growth and rose plant yield through cutting propagation. Keywords: auxin, flower appearance time, growing media, indole–3–butyric acid, rose cuttings

Abstract

Green mustard greens. Samhong King variety (Brassica rapa subsp. chinensis) is a popular vegetable in Indonesia. Green mustard greens have the advantage of being able to grow in both low and high elevations. The application of biochar in soil can help to improve its chemical qualities. The study employed a factorial randomized block design with two components. The treatment factor was the incubation duration of coconut fiber biochar at four levels: control, two weeks, four weeks, and six weeks. The amount of liquid organic fertilizer applied at four different levels: 1 mL/L water, 2 mL/L water, 3 mL/L water, and 4 mL/L water.The study found that coconut fiber biochar and liquid organic fertilizer had no significant effect on nutritional absorption in plant tissue or Samhong King mustard plants, however they did have the highest absorption of K, P, and N nutrients. The incubation period of coconut fiber biochar and liquid organic fertilizer had no significant effect on Samhong King mustard plant production, but the coconut fiber biochar treatment with a 6-week incubation period produced the highest yield, 2.96 t/ha. The treatment of liquid organic fertilizer yielded the best results. Keywords: Brassica rapa subsp. Chinensis, mustard Samhong King, plant nutrients, soil improver

Abstract

Fermented dairy products, such as yogurt, are well known for their health advantages. Enhancing their functional value using polyherbal mixtures constitutes a big step forward in functional food development. This study looks at the proximate composition (fat, protein, moisture, and ash content) and antioxidant activity of polyherbal yogurt enriched with green tea, cinnamon, and fenugreek seed extracts. Formulations were created with varied amounts of polyherbal extract at 0% (P0), 1% (P1), 2% (P2), and 3% (P3), with Lactobacillus bulgaricus and Streptococcus thermophilus as starter cultures (Lactina Ltd). A completely randomized design with three replications was used, and the data were analyzed using ANOVA at a 95% confidence level. The results showed substantial variations in fat (2.84−3.62%) and moisture (88.17−8.83%) content between treatments. Protein (3.92−5.03%) and ash level (0.76−0.77%) met the Indonesian National Standard (SNI) for yogurt. Polyherbal yogurt demonstrated considerably higher antioxidant activity and capacity than the control. The control yogurt (P0) had a poor antioxidant capacity of 60.81±10.89%, while polyherbal yogurt (P1, P2, and P3) had a high antioxidant capacity ranging from 252.40±11.20% to 267.44±1.44%. These findings indicate that including polyherbal extracts into yogurt not only ensures compliance with national nutritional standards (SNI), but also considerably increases antioxidant potential. Thus, polyherbal yogurt is an appealing prospect for development as a beneficial dairy product. Keywords: antioxidant, polyherbal, proximate, yogurt

Abstract

Yogurt has become a popular dairy product and is considered a promising candidate for functional food intake. Innovations in yogurt production continue to develop, increasing public interest in yogurt consumption by using herbal plants. The combination of active ingredients from multiple herbal plants may provide higher effectiveness compared to single herbal plants. Lactic acid fermentation in herbal plants significantly increases phenolic and flavonoid levels. This study aims to analyze the effect of polyherbal (green tea, fenugreek seed, and cinnamon) on yogurt with physical and chemical parameters. This study was conducted with the stages of making polyherbal extract, preparing polyherbal yogurt, and analyzing physical (viscosity) and chemical (pH, total titrated acid (TTA), total phenolic content, and total flavonoid content using a completely randomized design with four different polyherbal levels (0%, 1%, 2%, and 3%) in triplicates. Physical and chemical characteristics data were summarized using analysis of variance. The lactic acid fermentation process in yogurt form on polyherbal had a significant effect on chemical characteristics, such as pH, TTA, total phenolic and flavonoid contents. The best treatment level in this research is 3% polyherbal extract addition because it contains the highest total phenolic and flavonoid. Keywords: fermentation, Lactobacillus bulgaricus, polyherbal, Streptococcus thermophillus, yogurt
