Abstract

One of the most popular vegetables is the long bean (Vigna sinensis L.). Due to the presence of Rhizobium bacteria nodules in its roots, long bean plants are considered soil enrichers. Liquid organic fertilizer from goat urine is highly soluble in soil and contains essential nutrients crucial for soil fertility. This study aims to ascertain the best fertilizer dose for plant development as well as the effects of goat urine organic fertilizer, NPK fertilizer, and their combination on the growth of long bean plants (Vigna sinensis L.). A completely randomized design was used to perform the study as an experiment (CRD). With the aid of SPSS for Windows 25, two-way ANOVA was used for data analysis. Post hoc analyses were performed using DMRT and were allowed if the p-value (sig) was less than 0.05 or if the computed F value was greater than the tabular F value. The combination of goat urine organic fertilizer (POC) and NPK fertilizer did not substantially alter the development of long bean plants, according to the findings of the ANOVA study on the plant height parameter. Significant variations were seen, nonetheless, for other metrics as chlorophyll content, wet and dry weights, leaf area, and number of leaves. At the 5% significance level, the impact of treatments on plant height metrics showed that either the alternative hypothesis, H1, or the null hypothesis, H0, was accepted. Thus, it can be said that there is a strong interaction between the growth of long bean plants and the combination of NPK fertilizer and goat urine organic fertilizer (POC).

Abstract

Self-harm behavior is a form of behavior that is carried out to overcome emotional disturbances or emotional pain that is felt by self-harm without any intention to commit suicide. Borderline personality disorder (BPD) is a psychiatric disorder characterized by abnormal patterns of inner experiences and behaviors that affect cognition, emotion, interpersonal functioning, and impulse control. This study was conducted to review various aspects related to self-harm behavior on the borderline personality disorder. . In this bibliography summary we conducted a search on the PubMed database using the search keyword “Borderline Personality Disorder”. The inclusion criteria that we have set include using free full text publications and using English. We also used publications published over the past ten years, as well as publications with relevant discussion of Borderline Personality Disorder. Therefore, appropriate management is required. Some of the treatments include psychoeducation and psychotherapy as well as pharmacological treatment in severe cases. From the 21 literature used, it is stated that self-harm behavior in personality disorders borders on one of the disturbed domains, namely behavioral dysregulation. This dysregulatory behavior can influence CBD sufferers to injure themselves or even attempt suicide.

Abstract

Bacteria have an important role in providing essential nutrients for plants in dry land through various beneficial working mechanisms. One of the main mechanisms is the involvement of bacteria in nutrient cycles, such as the nitrogen cycle. The aim of this research was to determine the type and ability of bacteria in the rhizosphere of neem (Azadirachta indica) to fix nitrogen. The method used in this research is an exploratory descriptive type. The results of the isolation carried out from the rhizosphere of neem (Azadirachta indica) taken from the East Lombok area of Jerowaru sub-district, 5 samples were obtained with the code LO, where 2 isolates had the ability to fix nitrogen, namely LO3 and LO4. This is proven by using NFB media where there is a change in the color of the media from green to blue, and quantitatively using a spectrophotometer with results of 1,112 ppm and 2,156 ppm, respectively. The results of the molecular identification of the potential bacteria, namely LO4, using the BLAST method at the GenBank data base (NCBI), show that LO4 is the closest relationship to the species Lysinibacillus fusiformis strain SMC303. The results above show that rhizobacteria isolated from neem have the potential to be developed as a biofertilizer that can be applied to future cultivated plants.

Abstract

Phosphate solubilizing rhizobacteria are microorganisms that live in the rhizosphere of plants and have the ability to increase the availability of phosphate in the soil, thereby reducing dependence on chemical fertilizers which are harmful to the environment. This research aims to isolate rhizosphere bacteria from Lamtoro plants and test their ability to dissolve phosphate. Screening the ability of these bacterial isolates was carried out using Pikovskaya media and quantitatively using a spectrophotometer. The test results showed that there were 3 isolates, namely KLU13, A2 and KLS1, which had IKF values in the medium category. Meanwhile, the other 4 isolates had abilities in the low category (isolates A1, A31BK, A3BB and A3). The results of quantitative tests with a spectrophotometer showed that there was an increase in dissolved phosphate from day 2 to day 6. Isolates KLU13, A3 and KLS1 dissolved the highest phosphate on day 6 with values of 14.65 ppm, 14.81 ppm and 10.32 ppm respectively. It can be concluded that the isolate obtained from the Lamtoro rhizosphere which grows in the dry areas of Lombok Island has the potential to be developed as a biofertilizer in the future.

Abstract

Excessive use of antibiotics in treating infectious diseases has caused some bacteria to become resistant. Therefore, it is hoped that the use of natural ingredients such as cloves can be an alternative solution in reducing excessive use of antibiotics. This study aims to test the inhibitory effect and minimum killing power of clove flower oil (Aromatic syzygum) with water as a solvent against Staphylococcus aureus. In determining the inhibition zone, the diffusion disk method was used. Meanwhile, determining the Minimum Kill Ability (MKA) uses the liquid tube dilution method. The results showed that an increase in the concentration of clove flower extract was followed by an increase in the inhibition zone in the media with the isolate Staphylococcus aureus. Meanwhile, in measuring the Minimum Kill Ability, the results showed that the MKA value of clove leaf extract against bacteria Staphylococcus aureus smaller than 5%. This shows that only a 5% concentration of clove leaf extract is enough to inhibit growth Staphylococcus aureus. These findings indicate the potential of clove leaf extract as an antimicrobial agent for bacteria Staphylococcus aureus. So it is hoped that natural ingredients will be able to reduce excessive use of antibiotics.
