Abstract

Currently, many teaching resources have not fully understood how to write and submit to a journal. This can be attributed to various factors, such as a lack of training or experience in journal writing, a greater focus on teaching or research activities, or limited opportunities to engage in journal writing communities. Therefore, this workshop aims to enhance the capacity of teaching resources in writing and publishing research and community service in national journals. The implementation method consists of preparation, activity execution, mentoring, and evaluation stages. The results of the activity evaluation show that 80% of participants have improved their abilities to comprehend the structure of scientific journals, writing ethics, effective writing techniques, and 100% of participants are capable of drafting journals according to environmental style guidelines. Measured capacity development of teaching resources enables them to write journals in accordance with the guidelines of each publisher, avoiding rejection. Furthermore, the ability to understand the Open Journal System (OJS) application during submission is essential for teaching resources to publish in nationally accredited journals.

Abstract

Cancer death cases have increased yearly, and there are estimated to be 21.6 million cancer cases in 2030. Studies of herbal compounds for cancer treatment alternatives are essential because cancer treatment is relatively expensive and has adverse effects. Phyllanthus niruri (Pn) and Catharanthus roseus (Cr) are plants that are known as herbal medicines. Combining the two plants is expected to prevent and enhance the immune system in breast cancer cases. This study aims to analyze the anti-cancer and immunomodulatory effects of P. niruri and C. roseus extract (PCE) in modulating macrophage polarization in breast cancer mice. Experimental animals are divided into six groups and there is healthy control (normal mice), cancer (DMBA-induced mice), cancer mice with cisplatin administration, cancer mice with PCE administration with three different doses, including dose 1 (500 mg/kg Pn + 15 mg/kg Cr), dose 2 (1000 mg/kg Pn + 75 mg/kg Cr), and dose 3 (2000 mg/kg Pn + 375 mg/kg Cr). The mice were injected with DMBA once a week for six weeks to induce cancer in mice. The breast cancer mice model was administered with PCE orally for 14 days. The expression of CD11b+IL-10+ and CD11b+IFN-γ+ demonstrated macrophage polarization. The results showed that breast cancer induction using DMBA increased the level of IL-10 and decreased the level of IFN-γ significantly compared to the normal group (p < 0.05). In specific doses, administration of PCE could reduce IL-10 levels and increase the level of IFN-γ significantly (p < 0.05). PCE can modulate the polarization of macrophages by suppressing the M2-like macrophage and increasing the M1-like macrophage. The ability of PCE to modulate macrophage polarization indicates that the combination of P. niruri and C. roseus has activity as an anti-cancer.

Abstract

In recent years, the development of probiotic-based fermented products with halal status has been a concern. The use of growth medium has relied on de Man Rogosa and Sharpe (MRS) as a relatively expensive standard medium, and its halal status is still uncertain. Extensive research has been carried out to investigate the development of low-cost halal alternative media for the cultivation of probiotic lactic acid bacteria (LAB). This study aimed to develop a probiotic halal and low-cost culture medium using a tofu whey-based medium. This study used three tofu whey-based media – A (tofu whey 100%), B (tofu whey 94.5%, molasses 3%, skim milk 2.5%), C (tofu whey 92.5%, molasses 3%, cheese whey 2.5%, tomato extract 2%), and MRS broth as a standard medium. Bacterial populations, total sugars utilized, total lactic acids produced, low pH (2.0) tolerance, and high bile salt concentration (oxgall 1.5%) were assayed. The highest bacterial population after 48 h of incubation was shown by medium B compared to medium MRS (12.34 ± 0.87 and 11.48 ± 0.3 log CFU/mL). Total sugars utilized by 48.28 ± 2.89, 38.89 ± 6.94, 39.14 ± 4.24, and 76.00 ± 1.41 %; on the other hand, total lactic acids produced by 0.16 ± 0.12, 0.03 ± 0.04, 0.31 ± 0.03, and 2.25 ± 1.48 % in A, B, C, and MRS, respectively. Probiotic tolerance at low pH and the presence of bile salts of Lactiplantibacillus plantarum D4 consistently showed a high survival rate in medium B compared to MRS. Based on these results, the components and proportions used in medium B were suitable for the growth of L. plantarum D4 as a halal probiotic starter candidate.

Abstract

Staphylococcus aureus becomes a normal flora in humans, especially on the skin and in the nose. However, if it becomes excessive or if there are pathogenic variants, it can cause various health problems. The purpose of the study is to develop a molecular-based detection method for Staphylococcus aureus using the norA primer gene. The norA gene in Staphylococcus aureus is known to play a role in pathogenesis with its antibiotic resistance ability. This type of research is analytical observational with a cross-sectional method. The methods in the study include the isolation and identification of Staphylococcus aureus from healthcare facility equipment. Isolation and identification include bacterial isolation using Blood Agar Plate (BAP) media; isolate purification, Gram staining; biochemical tests using Mannitol Salt Agar (MSA) media, glucose tests, Voges Proskauer (VP) tests, catalase tests, and coagulase tests. Furthermore, S. aureus isolates were tested using a molecular-based method, namely Polymerase Chain Reaction (PCR). This method includes DNA isolation stages, qualitative testing with agarose gel electrophoresis, semi-quantitative testing with image J software, amplification with Real-Time Polymerase Chain Reaction (RT-PCR) using norA gene primers. The Mann-Whitney test results gave a value of p = 0.334 (p> 0.05) indicating the suitability between the culture method and the PCR method with the developed protocol in detecting Staphylococcus aureus. The developed method includes the use of base sequences in the norA gene primer, optimization of annealing and extension temperatures, and the concentration of DNA templates used.

Abstract

Background: Obesity is a global epidemic caused by excessive body fat, which is increasing free fatty acids in the liver, causing oxidative stress and liver cell damage. Green tea yogurt (GTY) with encapsulated Lacticaseibacillus paracasei E1 (GTY-LpE1) might have a beneficial effect in reducing liver cell damage. This study was conducted determine GTY-LpE1 effect on superoxide dismutase (SOD) expression, malondialdehyde (MDA) expression and liver histopathology in high-fat high-fructose diet (HFFD) mice. Material and Methods: A completely randomized design (CRD) with 7 groups, including normal diet (ND) group, HFFD group, 1.3 mg/kg BW simvastatin (SIM)-administered HFFD group, 5 g/kg BW probiotic yoghurt (PY)-administered HFFD (PY), 2.5 g/kg BW GTY-administered HFFD (2.5 GTY), 5 g/kg BW GTY-administered HFFD (5 GTY), and 10 g/kg BW GTY-administered HFFD (10 GTY). The diet was given for 16 weeks, followed by oral administration of sim/yoghurt during the last 4 weeks. Mice were sacrificed and the liver was collected. SOD and MDA expression were analyzed by flow cytometry. Histopathology analysis was done by evaluating hematoxylin-eosin (HE) staining of the liver.Result: The percentage of necrotic cells were 34.55, 34.31, and 21.95%, when treated with 2.5, 5, and 10 g/kg BW with GTY-administered HFFD, respectively, these were lower than the ones in the HFFD group (69.49%). The percentage of MDA expression were 15.55, 18.69, and 22.42%, respectively, these were lower than the ones in the HFFD group as well. The percentage of SOD expression were 9.49, 7.85, and 11.11%, respectively, these were higher than the ones in the HFFD group (3.44%). Conclusion: GTY-LpE1 could decrease the number of necrotic cells in the HFFD mice livers and improve the hepatocyte damage by reducing MDA expression and enhancing SOD expression. GTY-LpE1 can be used as an alternative food to control obesity.Keywords: alginate, chitosan, encapsulation, green tea, probiotic

Abstract

The implementation of Merdeka Curriculum in high school requires Biology teachers to face new challenges in teaching, especially the topic of microbial evolution. Microbes play an important role as a model in understanding the evolutionary process, including through CRISPR technology (genome editing). In addition, the mechanism of antibiotic resistance is also a clear example of evolution through genetic changes. However, limited access to information and facilities is an obstacle for teachers in developing appropriate learning modules. This service activity aims to improve the insight and competence of Biology teachers related to microbial evolution, through the introduction of CRISPR technology and antibiotic resistance, both in theory and practice. The training began with a pre-training survey on antibiotic use, material delivery and continued with antibiotic sensitivity test practice. Evaluation in the form of pretest and posttest was also given to participants who were categorized on a scale of understanding: very low, low, medium, high, and very high. The training participants had sufficient experience in the use of antibiotics before the training, but their understanding of antibiotics still varied. The pretest results obtained an understanding of 8.3% very low, 20.8% low, 33.3% medium, 33.3% high, and 4.2% very high. The posttest results showed a significant difference, with only two categories, 38.1% high and 61.9% very high. This result shows that the participants' understanding has increased by 28.4% with an average pretest score of 62 and posttest score of 87. In addition, participants were also able to conduct antibiotic sensitivity tests and how to interpret the data. The participants' response was very positive, with a satisfaction index score between 94-97 which is classified as very good. The theory and practice obtained are expected to increase teacher innovation in learning for students to understand microbial evolution.

Abstract

Background: Obesity-induced inflammation causes hematopoietic stress, disrupting bone marrow homeostasis. Green tea yogurt supplemented with Lacticaseibacillus paracasei E1 microcapsules (GTYP) is a promising way to overcome obesity due to its high antioxidant and anti-inflammatory activity. However, GTYP effects on blood production, specifically erythrocytes and B cells, remain unexplored.Materials and methods: Male Balb/C mice were fed either a high-fat fructose diet or a normal diet for 12 weeks. Microencapsulation was done by double coating of alginate-chitosan. There were seven groups in this study: normal diet (ND), high-fat fructose diet (HFFD), HFFD with 1.3 mg/kgBW Simvastatin (T1), HFFD with 5 g/kgBW plain yogurt (T2), HFFD with 2.5 g/kgBW GTYP (T3), HFFD with 5 g/kgBW GTYP (T4), and HFFD with 10 g/kgBW GTYP (T5). Erythrocyte counts from the peripheral blood were taken weekly. After 28 days of treatment, mice were sacrificed, bone marrow (BM) and lymphocytes were isolated. The cells of Ter119+, Ter119+CD59+, and B220+SDF-1+ were measured using flow cytometry.Results: HFFD not only reduces the peripheral erythrocyte count (2.15×109 cell/mL) but also affects the hematopoietic system, depleting Ter119+ (11.76%), TER119+CD59+ (0.050%), and B220+SDF-1+ (0.465%). Mice receiving 5 g/KgBW GTYP improved erythrocyte count (9.95×109 cells/mL). The parameters of erythrocyte and B cell development showed more remarkable improvement with GTYP treatment than simvastatin and plain yogurt (p<0.05). Molecular docking also indicated a great inhibitory effect of EGCG (-7.7) for the CXCR4 receptor.Conclusion: GTYP can potentially increase erythrocyte count and B cell development, particularly under obese conditions.   Keywords: anti-obesity, B lymphopoiesis, erythrocyte count, green tea yogurt, probiotics

Abstract

Ringinkembar Village, Sumbermanjing Wetan District, Malang Regency, is one of the centers for cocoa plantations using an organic farming system. However, over time this organic farming system experienced a decrease in fruit production, possibly from soil fertility and biofertilizers that were less available in the soil. This study aims to analyze the nitrogen-fixing ability and identify rhizosphere isolates that excel in nitrogen-fixing obtained from the rhizosphere of cacao (Theobroma cacao L) plant. Bacteria were isolated from the soil surrounding cocoa plant roots and grown on Nfb (Nitrogen free Bromothymol Blue) agar media. The nitrogen-fixing bacteria were analyzed with quantitative and qualitative methods. Six potential nitrogen-fixing isolates were identified based on the 16S rDNA sequence. The total number of isolates obtained from nitrogen-fixing isolation was six isolates. The R3.FN1 isolate showed the highest ammonia index at 0.52 µg.L-1 and was identified as Stenotrophomonas maltophilia KB13 with 99.87% similarity to the 16S rDNA sequence. Keywords: Cocoa, Nitrogen-fixing, Rhizosphere, Stenotrophomonas maltophilia.
