Abstract

This study aims to determine the effect of IAA-producing bacteria and phosphate solvents from the rhizosphere of Serbania grandiflora (L.) Pers on the germination of Vigna radiata (L.). This research began by isolating the rhizosphere bacterium Serbania grandiflora (L.) Pers, which was then characterized by cell morphology, grammatical and morphological characteristics. The ability of bacteria to dissolve phosphate was evaluated qualitatively by observing the presence of clear zones in Pikovskaya media, and quantitatively with a spectrophotometer. The isolate's ability to produce IAA was tested quantitatively using Salkowski reagent, and quantitatively using a spectrophotometer. For the effect of isolates on the growth of green beans, a completely randomized design (CRD) research design was used, with 4 treatments, namely P0 (sterile distilled water); P1 (IAA-producing bacterial culture); P2 (phosphate solubilizing bacterial culture); P3 (IAA producer and phosphate solubilizer). Vigna radiata L. seedling growth test was carried out in vitro on Murphy's medium. The research data were analyzed using the one-way ANOVA test. The results showed that 5 isolates had the ability to dissolve phosphate, with a phosphate solubility index ranging from 1.70-2.14, where isolate RT7 showed the highest value. The isolate's ability to produce IAA at concentrations ranged from 7.1 - 62.7 ppm, with the highest value shown by isolate RT6. The results showed that treatment with IAA-producing bacterial isolates plus phosphate solubilization properties showed a significantly different effect on Vigna radiata L. plant height compared to other treatments.

Abstract

This study aims to test the ability of endophytic bacterial isolates of cayenne pepper roots (Capsicum frutescens) to produce siderophore compounds and protease enzymes and to test the antagonistic activity of endophytic bacterial isolates in controlling the growth of plant pathogenic bacteria (Ralstonia solanacearum). The stages in this study are isolation of endophytic bacteria from cayenne pepper roots, siderophore production test, protease enzyme activity test, and biochemical and physiological characterization of potential endophytic bacteria, antagonistic test of endophytic bacteria against the growth of Ralstonia solanacearum bacteria. Endophytic bacteria were isolated from cayenne pepper plant roots taken from Selong, East Lombok. Characterization of siderophore-producing isolates used the Arnow test method. The activity of bacterial protease enzymes was tested qualitatively on Skim Milk Agar solid media. The antagonistic activity test of endophytic bacteria against pathogenic bacteria was carried out using the Kirby-Bauer diffusion method. Characterization of endophytic bacteria was carried out by observing colony morphology, Gram staining, and biochemical tests. There were 3 isolates that were able to produce siderophores (catecholate type) with codes EC5, EC12, and EC15. Six isolates showed protease enzyme activity with codes EC3, EC4, EC5, EC7, EC11, and EC15, with the highest Proteolytic Index (2.02) shown by isolate EC4. There were 3 isolates that were able to inhibit the growth of Ralstonia solanacearum (EC4, EC5, and EC15), with the highest inhibitory power shown by isolate EC15 (3.67 mm). The results of the study indicate that endophytic bacteria from cayenne pepper plant roots have the potential as biopesticides in the future.

Abstract

Rhizobacteria that are able to dissolve P and produce IAA can be used as component of biofertilizers to help increase plant growth, which can be a more environmentally friendly fertilizer alternative compared to chemical fertilizers. Rhizobacteria originating from sub-optimal environments have the potential to overcome environmental stress such as osmotic stress. To obtain potential isolates that can be used as biofertilizer, exploration of the rhizosphere of the sentigi (Pemphis acidula) has been carried out from the coast of Gili Sulat, Lombok. The method for isolating and selecting IAA producing bacteria was carried out using the colorimetric test method, while for the P solubilization ability, it was carried out by growing rhizobacteria on Pikovskaya media. Isolate PA6 with the highest IAA producing ability (21 ppm) and PL4 with the highest P solubilizing ability (20.9 ppm), were tested for their effect on the growth-promotion of Vigna radiata cultured on Murphy agar media by measuring the parameters of plant height, root length, fresh weight, and plant dry weight. Based on the One Way ANOVA statistical analysis with a p value ≤ 0.05, it showed that the inoculation of IAA-producing and P solvent rhizobacteria was proven to be able to have a significant effect with significantly different results on increasing plant dry weight. In the future, the isolate obtained can be developed into a biofertilizer component that can be applied in saline and dryland agriculture.

Abstract

Nutritional knowledge is a crucial factor in determining health and the balance between physical and mental development. Nutritional knowledge plays a crucial role in shaping a person's eating habits because it influences the types and amounts of food they choose. This study aimed to examine the relationship between nutritional knowledge and eating patterns among fifth-grade students in public elementary schools in Kediri District, West Lombok Regency, Indonesia. Using a quantitative approach with a cross-sectional design, data were collected from 221 students selected through simple random sampling from eight schools. Nutritional knowledge was measured using a multiple-choice test, while eating patterns were assessed through a structured questionnaire. Data analysis involved Chi-Square and Pearson correlation tests. The results showed a significant relationship between nutritional knowledge and eating patterns (p = 0.001), with a moderate positive correlation (r = 0.530). Most students demonstrated moderate nutritional knowledge (46.6%) and good eating patterns (66.5%). These findings suggest that higher nutritional knowledge is associated with healthier eating patterns. However, knowledge alone is not sufficient to ensure optimal eating behavior, as other factors such as family environment, food availability, and habits also play important roles. Strengthening nutrition education in schools and engaging parents in promoting healthy eating are recommended to improve students' dietary habits.
