Abstract

Hermetia illucens larvae, also known as the black soldier fly larvae, are best known as the decomposers of organic matter. There are many potential microbes found in the feces of BSF larvae. This research aimed to isolate the chitinolytic bacteria from chicken manure maggot waste, identify the antifugal activity, hydrolytic enzyme activity, phosphate and potassium solubilization, and bacterial species through 16S rRNA gene analysis. The initial screening focused on bacteria with chitinolytic ability. Antifungal activity tests were performed against phytopathogenic fungi, Colletotrichum sp. Isolate MKP02 showed the highest activity in inhibiting the growth of Colletotrichum sp. up to 100% and produced protease and cellulase enzymes, along with the ability to solubilize potassium. Furthermore, the potential isolate MKP04, the isolate shows the highest cellulolytic activity with a percentage of 300%. It can inhibit Colletotrichum sp. fungi, as well as having lipase enzyme content, and being able to dissolve potassium. The results of 16S rRNA gene amplification on the two isolates showed that both isolates were close to bacteria of the genus Lysinibacillus and Brevibacterium. This research is expected to provide valuable information about the bacterial content, levels of hydrolytic enzymes, and the ability to solubilize phosphate and potassium in BSF.

Abstract

Atherosclerosis is triggered by cholesterol accumulation in endothelial layers that induces the production of inflammatory cytokines, including TNF-α, IL-6, and IL-10. This condition disrupts microRNA homeostasis like miR-29b-3p, generally maintaining artery health. Steamed tomatoes contain higher antioxidant properties than raw, which might be better against atherosclerosis. However, its influence on inflammation and miR-29b-3p balance remains unclear. This study aims to elucidate the effect of steamed tomatoes on the TNF-α, IL-6, and IL-10 levels and miR-29b-3p expression under atherosclerosis conditions. Sprague Dawley male rats were equally divided into K1 group of healthy rats given a placebo; K2 group was atherosclerosis rats induced with 2 m of cholesterin/ 200 g/KgBW per day, then K3 and K4 groups were atherosclerosis rats supplemented with 20 mg/ 200 g/KgBW per day of atorvastatin and 16 mg/ 200 g/KgBW per day of steamed-tomato extract for 60 days. Steamed tomato decreases cytokine level in the K4 group and significantly differs from all groups (p < 0.050). This study showed that increased proinflammatory cytokine, including TNF-α and IL-6, is hypothetically involved in plaque formation and lamina layer destruction in endothelial. Steamed tomato supplementation also significantly increases miR-29b-3p expression to 0.98 ± 0.33 log10 fold change higher than K2 and K3 (p = 0.000). This study demonstrated the potential of steamed tomatoes to improve dyslipidemia, atherosclerosis-related inflammation, and miRNA homeostasis. This research provides additional knowledge regarding determining the expression of miR-29b-3p, which has the potential to be developed as a diagnostic or therapeutic target.

Abstract

Breast cancer is a chronic health problem that causes 690,000 deaths worldwide. The development of secondary metabolite compounds from natural preparations through an in silico approach is needed as a predictive tool to prevent breast cancer, one of them is cladosporol from Cladosporium spp. This study aims to utilize an in silico approach to predict the potential of cladosporol against alpha-estrogen receptors. The alpha-estrogen receptor with code 6CBZ was selected based on group function as pharmacophore in ligand-receptor interaction. The methods used in this study are by using an in silico approach with Molegro Virtual Docker (MVD) Ver 5.5 for the docking process and CABS-flex 2.0 for identifying the stability of the complexes. ADMET properties analysis was also performed to know the pharmacokinetics attributes of cladosporol. Based on research conducted, stated that cladosporol octanoate has the lowest rerank score with a -84.3593 value and the RMSD value is 1.195 Å so it’s valid for molecular docking. Exploration of cladosporol for anti-breast cancer from Cladosporium spp fungi can be a novelty for the development of future pharmaceutical research. Thus, the development of anti-cancer drugs for early prevention can be carried out to reduce the number of breast cancer cases worldwide.

Abstract

Porang (Amorphophallus oncophylus) tubers are one of the export commodities due to their glucomannan content. This study aimed to investigate the characteristics of water fermentation and the quality of porang fermented flour with the addition of Lactobacillus plantarum (LP), Bacillus subtilis (BS), and Saccharomyces cerevisiae (SC). Fermentation was conducted using four treatments, namely LP+BS, LP+SC, BS+SC which consisted of 10%v/v of inoculum, respectively, and LP+BS+SC which consisted of 7%v/v LP, 7% BSv/v, and 6%SCv/v. During fermentation, pH, total acidity, and total microorganisms were observed. Proximate, glucomannan content, starch content, fiber content, and antibacterial and prebiotics characteristics were observed for fermented porang flour. The results showed that pH decreased while total acidity increased during fermentation. Total aerobic bacteria had the highest population at 24 hours of fermentation while lactic acid bacteria had the highest population at 24- and 48-hour fermentation. Yeast reached the highest population at 72 hours of fermentation. Porang fermented flour with the addition of BS+SC contained the highest glucomannan content, carbohydrate, and fiber content. Moreover, the flour with BS+SC had an antibacterial effect against Escherichia coli and Staphylococcus aureus and supported the growth of Lactobacillus acidophilus. Porang fermented flour which is processed with the addition of a mixed culture of BS and SC can be developed to improve the nutrititional and functional properties of porang flour.

Abstract

Wound healing in hyperglycemia patients is still a challenge in the medical field. Bioactive compounds of binahong leaf extract can support the wound healing process. Nanoencapsulation of the extract can avoid oxidation and optimize drug delivery to target tissues. This study aimed to analyze the effect of nanochitosan encapsulated binahong extract ointment (NEBE/Oint) on the percentage of wound healing, angiogenesis, collagen density, and epithelial thickness in hyperglycemic rats. This study used 80 mg/kg streptozotocin-induced hyperglycemia rats injured in the back area. Rats were divided into P0 (0,9% NaCl), P1 (10% povidone-iodine ointment (PI/Oint)), P2 (10% NEBE/Oint), P3 (20% NEBE/Oint), P4 (30% NEBE/Oint). Phytochemical screening of binahong leaves extract showed positive results for flavonoids, alkaloids, saponins, and tannins. NEBE particle size was 169 nm with a size distribution of 0.2 and a zeta potential value of -40,2 mV. The results showed NEBE ointment had a significant effect when compared with negative control on wound healing hyperglycemic rats. The conclusion is that nanochitosan drug delivery has the potential as an alternative wound treatment. The novelty of this study is the use of nanochitosan to accelerate wound healing in hyperglycemic rats. The results of this study are expected to become a reference for new wound-healing methods in the medical field.

Abstract

Chronic lead exposure induces ROS accumulation which causes physiological disorders. Chelation therapy has been widely used to overcome lead poisoning since it exerts only a few side effects. Nano chitosan prevents lead poisoning by inhibiting ROS. This study examined the pharmacokinetics of nano chitosan in chronic lead-induced toxicity animal models and the mechanism of action pathway using the bioinformatic approach, The area under the curve was estimated to be 12110.13 ± 7709.37 μg/mL hours using the pharmacokinetic model, and the Cmax was 82.34 ± 5.64 μg/mL. The Tmax and t½ calculations were 22.68 ± 11.67 and 80.47 ± 60.58 hours respectively. Chitosan nanoparticles regulated VEGFA, FGF2, and LGALS3 which plausibly played a substantial role in chronic lead exposure. However, chitosan is not suitable for oral administration due to its low gastrointestinal solubility. These characteristics make chitosan nanoparticles have the prospect of being developed as a supplement so that they can contribute to overcoming the negative impacts of chronic lead poisoning.

Abstract

Cardamom is one of the prominent plants with significant economic value in the Banyumas Regency, Central Java, Indonesia. Although Javanese cardamom is traditionally categorized under Amomum compactum, the morphological variations observed create ambiguity about its exact species status. DNA barcoding using the maturase K (matK) and ribulose-bisphosphate carboxylase (rbcL) genes is proven as a reliable technique to elucidate the taxonomic status of morphological variable plant cultivars. This study aimed to characterize cardamom from Banyumas Regency using morphological and molecular approaches for taxonomic status identification and genetic diversity evaluation. The matK and rbcL genes were selected as genetic markers and sequenced using a bidirectional sequencing technique. Morphological examination showed significant color variations at the cardamom stem base. All samples had high genetic identities to reference species in databases and were supported by high query cover and zero e-values. Therefore, molecular characterization, alongside geographic distribution assessment, established that this plant belongs to a single species, Amomum compactum. Additionally, the analysis conducted showed a low level of genetic diversity, as evidenced by haplotype and nucleotide diversity. Low-level genetic diversity provides additional data to convince that cardamon in Banyumas Regency belongs to a single species. These results are essential data in seed selection for further cultivation.

Abstract

Synthetic textile dyes in the Tanjung Bumi batik coloring process in Madura, Indonesia, have been used extensively for decades, raising environmental concerns due to hazardous wastewater. This research aims to evaluate the quality characteristics of synthetic textile dye wastewater, assess batik artisans' awareness of batik waste hazards, and analyze the interaction between these factors. Wastewater samples were collected from four locations with two repetitions each. Thirty-seven batik artisans participated in a survey. The wastewater analysis included measurements of BOD5, COD, pH, TSS, phenol, Cr, NH3-N, sulfide, and oil and grease. The survey assessed the artisans' use of synthetic dyes and their awareness of environmental hazards. The results showed that the toxic substance levels in Tanjung Bumi batik waste exceed the quality standard thresholds for textile waste. Survey findings indicate that 100% of respondents use synthetic textile dyes, 83.78% dispose of waste without processing, and 91.89% are unaware of the hazards posed by synthetic textile dyes. There is a direct correlation between the artisans' low awareness of the negative impacts of waste and their lack of environmental preservation practices. The novelty of this research lies in its dual evaluation of chemical wastewater characteristics and socio-environmental awareness among artisans. This approach highlights the urgent need for educational interventions and improved waste management practices. The implications are significant for developing sustainable batik production methods and enhancing environmental awareness, contributing to broader societal benefits.

Abstract

Geosesarma shows intraspecific carapace color variation, which might lead to species misidentification. The problem can be solved using DNA barcoding. There is one research about Geoserarma from the southern slopes of Mount Slamet, but samples were only collected from the Banjaran River for morphological identification. Here, we collected samples from wider areas covering south slope and applied molecular identification. This research aims to assess Geosesarma diversity in south-slope Mount Slamet Central Java, Indonesia based on the cytochrome c oxidase 1 gene barcoding. Surveys were carried out at six sites. Taxonomic identification was done using the barcoding technique. Four morphotypes were obtained during the research. Three morphotypes with the square carapace were identified as Geosesarma, while the remaining one morphotype was included in Parathelphusa. The three Geosesarma morphotypes were barcoded as Geosersarma dennerle because their genetic identity was more than 97% of the G. dennerle sequence in Boldsystems. In contrast, the Parathelphusa morphotype was barcoded as P. convexa with a genetic identity of 97.50%. It can be concluded that the Geosesarma crab on the south-slope Mount Slamet only consists of one species but has carapace and claw color variations. The data are essential for Geosesarma market development and conservation in the region.

Abstract

The natural ingredient-based therapy extracted from various plants is assumed more tolerable to cancer patients’ bodies than synthetic drugs. To tell successful novel cancer therapy, an indicator is needed to confirm the result. VEGF is a pro-angiogenic factor that leads the cancer cells’ invasion to another organ and is associated with high mortality in patients. Hence, the VEGF level is widely used as one of the successful cancer therapy indicators. Purposed of research elucidated the effect of Mandarin orange peel ethanol extract (EEKJM) to improve the reduction of VEGF levels in colon cancer in vitro. This study was an experimental posttest and control group design to analyze different level of VEGF on cancer cells at end of the study.  Research began with the preparation of EEKJM followed by a cytotoxic extract test using the MTT assay method. Furthermore, the measurement of VEGF levels by the VEGF ELISA kit protocol. One Way ANOVA was performed to analyze data.Results showed the cytotoxic test of the EEKJM and doxorubicin against WiDr cells was 240 g/ml and 1.59 µg/ml. VEGF levels showed decreasing after being induced with EEKJM and doxorubicin with doses ½ IC50 and ¼ IC50. Conclusion: EEKJM was able to reduce VEGF levels and viability of WiDr colon cancer cells. The advantages are as much as initial evidence of the ability of the orange to treat cancer even though further animal studies or evidence of a pathway of decrease of the VEGF or other signals are required.
