Abstract

Banana is a plant with nutritious fruit and can help prevent stunting. Banana plants are widely cultivated in East Kalimantan, but the type characterization has not been identified. The purpose of this study was to determine the diversity of banana plants in East Kalimantan and to characterize banana plants based on morphology. This research is explorative in nature by identifying directly in the field the cultivated banana cultivars. Morphological characterization of stems, leaves and fruit was carried out based on the banana description contained in IPGRI-INIBAP/CIRAD. The research instrument is a banana morphology observation sheet which contains parameters: leaf habit, pseudostem color, predominant underlying color of the pseudostem, sap color, blotches at the petiole base, blotches color, petiole canal leaf III, color of leaf upper surface, color of midrib dorsal surface, color of leaf lower surface, color of midrib ventral surface, wax on leaves. The result shows that at East Kalimantan is found 12 types of banana cultivars were found, Talas bananas, Rutai bananas, Kepok bananas, Mas bananas, Morosebo bananas, Tanduk bananas, Susu bananas, Maulin bananas, Red bananas, Ambon bananas, Raja bananas, and Cavendish bananas.There are variations in the morphological characteristics of banana plants, leaves and fruit that can characterize each banana.

Abstract

Using the well diffusion method, papaya (Carica papaya L.) and water guava (Syzygium aqueum) leaf extracts were investigated for their capacity to inhibit Escherichia coli ATCC 25922. Samples came from North Samarinda's Paperta, Jalan Grogot, and Perjuangan neighborhoods. 96% ethanol was used for the extraction process, which was then blended in five different concentrations and repeated four times. The existence of alkaloids, flavonoids, tannins, saponins, steroids, and phenolics was demonstrated by the phytochemical data. With the exception of the positive control chloramphenicol, which had an average of 24.7 mm, the antibacterial test did not reveal an inhibitory zone at different concentrations.

Abstract

Salmonella typhi causes typhus, which continues to be a health challenge in various countries. One alternative to inhibit bacterial growth is to use antibacterial compounds from plants. Leaves of moringa (Moringa oleifera L.) and kirinyuh (Chromolaena odorata L.) have secondary metabolites that are known to have antibacterial properties. Determining the secondary metabolite composition of the two leaf types and evaluating the impact of extract combination on Salmonella typhi inhibition are the goals of this study. An experimental approach employing This investigation was carried out utilizing a completely randomized design (CRD), which included five different extract concentrations that were examined using the well diffusion method, a negative control, and a positive control (chloramphenicol). The outcome of phytochemical analysis show that both leaves contain alkaloids, phenolics, tannins flavonoids, steroids and saponins. However, the inhibition test showed that neither the single extract nor the combination of Moringa and kirinyuh leaves formed a clear inhibition zone, whereas the chloramphenicol used as a control was 28.9 mm. Thus, moringa and kirinyuh leaf extracts did not show antibacterial activity against Salmonella typhi. However, chloramphenicol proved successful in preventing these germs from growing.
