Abstract

Apple has the most fruit productio at Batu City. There are two apple  varieties; Manalagi cherry and Anna, but some apple varieties have low quality (grade D). The reason is because of low price and the consumers is not interesting to buy, so grade D apple decreased. An alternative to apply the grade D apple is by using for nata production with addition three sugar sort, that is cane sugar, palm sugar and siwalan sugar as a food diversification. This study aims to (1) examine the effect of varieties of apples on the quality of nata based on the weight, thickness and fiber content, (2) to examine the effect of three kinds of sugar on the quality of nata based on the weight, thickness and fiber content , (3) to analyze the difference effect of apples varieties and sugars sort that produce the highest quality nata. The results showed that (1) the apples varieties has significant effect on the nata quality based on the nata fiber content, but there is no significant effect of apples varieties on the nata quality based on the thickness and weight of nata. varieties Manalagi cherry variety produces the best nata quality based on the fiber content, (2) The sugar sorts significantly affect to the nata quality based on thickness, weight and nata fiber content. The use of palm sugar produces the best nata quality based on the thickness, weight and fiber content, (3) The interaction of apple varieties and sugars sorts significantly affect to the nata quality based on the thickness, weight and nata fiber content. Manalagi cherry variety with the addition of palm sugar gives the best nata quality based on the thickness, weight and fiber content

Abstract

Endophytic fungi are known to produce secondary metabolites with potential applications in the field of health, including flavonoids, terpenoids, tannins, and eugenol. The use of eugenol from clove (Syzygium aromaticum) plants has been widely studied to optimize its benefits. This study aims to evaluate the production of eugenol by endophytic fungi isolated from clove organs collected from Tongole and Marikurubu. The isolated endophytic fungi were identified as follows: Rhizoctonia sp., Diplococcium sp., Geotrichum candidum, Eupenicillium javanicum, Penicillium frequentans, and Aspergillus nidulans. Eugenol content was analyzed using gas chromatography (GC). The results showed that eugenol production varied significantly among isolates, with Geotrichum candidum from Marikurubu (0.44111 μg/mL) and Aspergillus nidulans from Tongole (0.37972 μg/mL) exhibiting the highest concentrations. In contrast, other isolates showed relatively low production levels. These findings suggest that eugenol biosynthesis is strongly influenced by fungal species rather than organ origin or sampling location. This study highlights the potential of selected endophytic fungi as an alternative source of eugenol.

Abstract

The objective of this study is to ascertain the pathogenic and antagonistic fungi that induce disease in avocado plants (Persea Americana Mill), identify the antagonistic fungi with the greatest antagonism potential among a variety of antagonistic fungi, and elucidate the mechanism by which antagonistic fungi inhibit the growth of pathogenic fungi. From January to May 2023, this study was conducted in vitro at the Microbiology Laboratory, State University of Malang, employing a completely randomized design (CRD) comprising six replications and four interventions. The identification of mold was accomplished through macroscopically and microscopically descriptive analysis, followed by a comparison with the mold identification key book. The antagonism process was executed utilizing the dual culture method on PDA medium, and the electron microscope (SEM) was employed to witness the antagonism mechanism. The research findings revealed that T. harzianum spp. and T. viride were identified as antagonist fungi, whereas C. aotearoa and C. gloeospoiroides were identified as pathogenic fungi. The antagonistic fungus T. viride exhibited the greatest degree of antagonism, impeding the growth of C. gloeospoioroides by 77.8%. Observed antagonism occurs when the hyphae of the antagonistic mold ensnare, entangle, and pierce those of the pathogenic mold, causing harm to the region surrounding the pathogenic mold's hyphae and subsequently impeding its growth

Abstract

Background: Escherichia coli cause diarrhea. E. coli infections can be treated using synthetic antibiotics. Natural antibiotics are an alternative for prevent E. coli infections as synthetyc antibiotic substitute. Natural antibiotics are come from plants part such as agung banana’s (Musa paradisiaca) bunch and combs. This bananas are used as a dessert fruits. The waste of this friut, such as bunches and fruit comb. This banana plant is potentially as antibacterial substance. The aims of this research are, 1) to examine the antibacterial effect of banana bunch and comb extracts; 2) to determine the effective concentration of the extract against the E.coli growth; and 3) to analysis of the active compounds content of banana bunch and comb extracts. Methodology: The antibacterial effect was examine using the agar well diffusion. Total active compound levels was examine using the UV-Vis spectrophotometry method and the derivative compounds uses the LCMS method. Findings: The research results showed the bunches had antibacterial effect against E. coli and the effective concentration is 90% with the highest inhibitory zone size diameter is 6.98 ± 0,00 mm, while the combs effective concentration is 80% is 6.55 ± 0.81 mm. The antibacterial effect of both extracts is moderate categorize. The highest content of active compounds in the bunches is phenol, with content: 70.70 mg/g and in the comb is 45.82 mg/g. Contribution: This research contributes to the utilisation of organic waste as an alternative source of environmentally friendly natural antibacterial agents and supports innovation in phytopharmaceuticals based on local plants.
