Abstract

Banana peel waste is one of the contributors to organic waste in Indonesia. By using banana peels as fertilizer, it is hoped that organic waste can be reduced. This research aims to determine the effect of Liquid Organic Fertilizer (LOF) from kepok banana peel (Musa acuminata) on the growth of mustard greens (Brassica juncea), using an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments with 4 replications, namely P0: control group (without banana peel waste LOF), P1 = 25 ml LOF, P2 = 50 ml LOF, P3 = 75 ml LOF, and P4 = 100 ml LOF. The parameters observed were plant height, number of leaves, and wet weight. The research data were analyzed using the ANOVA test with a significance level of 5% followed by the DMRT/Duncan test to determine the differences in effects between treatments. Giving 75 ml of banana peel LOF had the most effective effect with an average plant height of 16.75 cm, an average number of leaves of 7, and an average wet weight of 2.25 gr. From the results of the ANOVA test, the plant height was 7.95, the number of leaves was 1.17, and the wet weight was 16.00. From the three parameters, it was found that Fcount>Ftable (2.87) so it was concluded that giving 75 ml LOF of kepok banana peel had a significant effect on the vegetative growth of mustard plants compared to other treatments, especially on the parameters of plant height and fresh weight.

Abstract

Ashitaba (Angelica keiskei) is one of the plants cultivated in the Sembalun region, Lombok, NTB, which has the potential to be developed as a source of antioxidants. This study aims to determine the antioxidant activity of the methanol extract of ashitaba herb by measuring the inhibition against DPPH (1,1-diphenyl-2-picrylhydrazyl) radicals using a UV-Vis spectrophotometer. Ashitaba herb samples were collected in Jorong Hamlet, Sembalun Bumbung Village, Sembalun District, East Lombok Regency at coordinates 8°23'5.273" LAT - l16°32'12.016" EAST. The sample was then processed into simplisia with a simplisia yield of 14.75%. The simplisia was dechlorinated with n-hexane solvent and then extracted with 80% methanol solvent using the sonic method, giving a methanol extract of ashitaba herb yielding 20.30%. DPPH radical inhibitory activity was measured at a maximum wavelength of 516 nm and an operating time (OT) of 30 minutes. The methanol extract of ashitaba herb has an IC50 value of 129.40 ± 7.36 ppm, which shows moderate antioxidant activity, with a standard compound comparison of ascorbic acid with an IC50 value of 2.37 ± 0.06 ppm, which is classified as very potent.

Abstract

The research aims to determine the level of food security and the factors that influence the level of food security of farming households in the Dodokan watershed. The topography of the watershed from upstream to downstream certainly influences the water supply in each part of the watershed, namely in the upstream, middle and downstream parts, which has implications for the way farmers carry out business on the land they work on, both cropping and cropping patterns. This of course raises the assumption that farmers in upstream and middle areas will be more prosperous because of a better supply of natural resources and whether this will have an impact on production levels and income of farmer households. This research used a household survey of 68 farmers selected using proportional sampling. Cross-classification between expenditure and portion of household energy adequacy levels is used to answer the first objective. The ordinal logistic model is used to answer the second objective. The results of the research show that 27.94% of farmer households have achieved food security levels, 30.88% have less, 38.24% are vulnerable, and 2.94% have food insecurity. Based on the results of ordinal logistics testing, household food security is positively influenced by household income, number of household members, household expenditure and negatively by the housewife's education.

Abstract

Tamarind leaves (Tamarindus indica L.) contain compounds including saponins, flavonoids, and tannins. The content of tannin compounds in tamarind leaf extract (Tamarindus indica L.) is known to be used as an antidiarrheal bioagent. This study aims to identify antibacterial activity against Escherichia coli bacteria based on the potential of tamarind leaves (Tamarindus indica L.) as an anti-diarrheal bioagent. The design of this research is an experimental laboratory with randomized group design. The samples in this study were divided into 2 control groups, namely negative control (sterile aquades), positive control (ampiciilin), and 3 treatment groups, namely old and young tamarind leaf extract groups with each concentration of 25%, 50%, 75% and 100% with the number of samples for each treatment group as much as 3. Test the effectiveness of antimicrobials using the solid dilution method. The effectiveness of antimicrobials is demonstrated by the large diameter of the inhibitor on Muller Hilton Agar media. The results showed that the inhibitory power of young tamarind leaf extract ranged from 13.8 mm to 14.9 mm, while the inhibitory power of old tamarind leaf extract ranged from 10.7 mm to 11.9 mm, so that the inhibitory power of young tamarind leaf ethanol extract was greater than the type of old tamarind leaf ethanol’s extract.
