The Journal of Biomedical Sciences and Health (JBSH) accepts manuscripts in basic sciences and applied clinical research. It covers various fields of biomedical sciences, but is not limited to Medical sciences. Our journal accepts and publishes original articles and review articles that significantly contribute to the understanding of biomedical sciences and health. The Journal of Biomedical Sciences and Health is published biannually in the months of February and August. This journal is available for download to anyone, including students, researchers, and lecturers. Authors are not charged for publication in JBSH. JBSH is a journal that disseminates, discusses, and presents scientific literature to support other communities on health developments, thereby increasing the knowledge of scientists and health workers and ultimately improving the health of the global population. JBSH covers a wide range of topics, including: 1. Biomedical Sciences: Molecular biology, microbiology, anatomy, physiology, biochemistry, etc. 2. Health: Medicine, Nursing, Obstetrics, Public Health, Pharmacy, Radiology, Administration of Community Health Centers, Hospitals, and Health Services, Health analyst. Journal of Biomedical Sciences and Health (JBSH) is published by Program Studi Ilmu Biomedis Fakultas Ilmu Keperawatan dan Kesehatan Universitas Karya Husada Semarang. JBSH is expected to increase its visibility through scientific studies and research findings accessible to academic circles and researchers.

Abstract

Background: For a probiotic to offer health benefits, it must stay viable through the tough environment of the human gastrointestinal tract. This study assesses the effectiveness of sodium alginate encapsulation in improving the survival of Lactobacillus LG71, a new strain from mangrove sediment, under simulated gastric and intestinal conditions. Objective: This study aims to evaluate the effectiveness of sodium alginate encapsulation in enhancing the viability and survival of Lactobacillus LG71, a probiotic strain isolated from mangrove sediment, during cold storage and under simulated gastric and intestinal conditions. Methods: Lactobacillus LG71 was encapsulated in sodium alginate beads. The viability of both encapsulated and free (non-encapsulated) cells was assessed over a 4-week storage period at 4 °C and during sequential exposure to simulated gastric and intestinal environments. Results: Encapsulation significantly improved survival rates compared to free cells (p < 0.05). Although both groups experienced a decline during the first week of storage, encapsulated cells maintained a high viability of approximately 107 CFU/mL, losing only 2.51 log CFU/g over four weeks. Most notably, encapsulated Lactobacillus LG71 demonstrated greater resilience during digestion, retaining populations of 2.21 log CFU/mL in gastric simulations and 1.00 log CFU/mL in intestinal simulations. In contrast, free cells were much more vulnerable to these acidic and enzymatic conditions. Conclusion: Sodium alginate encapsulation effectively protects Lactobacillus LG71 from environmental and biological stressors. These findings indicate that encapsulation is a crucial step for the commercial application of mangrove-derived probiotics, ensuring that a viable dose of living cells reaches the host's lower gastrointestinal tract to promote health benefits.

Abstract

Background: The habit of eating snacks at school is part of the diet of elementary school students who need attention related to their nutritional quality. Knowledge and attitude are often considered determining factors in  choosing  healthy  snacks.  Objective:  This  study aims  to  analyze the relationship  between gender  and  students'  knowledge  and  attitudes  towards  choosing  healthy snacks  at  Semarang  City  State  Elementary  School.  Methods:  Quantitative  study  with  cross- sectional design. The sample consisted of 74 students taken from 21 State Elementary Schools in Semarang  City  using  quota  sampling  techniques.  Data  was  collected  through  a structured questionnaire and  analyzed  using  Chi-Square statistical  tests.  Results:  The univariate  analysis showed that the majority of respondents were female (59.5%), had good knowledge (89.2%), and had good attitudes (41.9%). The results of the bivariate analysis showed no relationship between gender  and knowledge of  healthy snack  selection  (p  value=  1.00)  and  no  relationship between gender and attitudes towards healthy snack selection (p value = 0.196).  Conclusion: Gender is not  a  distinguishing  factor  in students'  knowledge and  attitudes  towards healthy snacks.  This suggests  that  school  health  interventions  should  focus  more  on  strengthening  the  physical environment and the availability of healthy snacks in schools, regardless of gender.

Abstract

Background: Lactic Acid Bacteria are a group of bacteria that have the ability to produce antimicrobial compounds called bacteriocins. Antibacterial of lactic acid bacteria proved effective in inhibiting pathogenic bacteria that cause infection in humans such as Shigella sp and Salmonella sp. Lactic acid bacteria can be found in fermented foods, one of which is fermented food typical of West Kalimantan, namely cincalok Aim: This study was to determine the antibacterial potential of cincalok lactic acid bacteria against Shigella sp and Salmonella sp Methods: This study used a true experimental, with the research design using a post test only control group design with data analyzed using SPSS to evaluate inhibition zone differences among three treatment groups: bacteriocin from Weissella sp. at 24 hours, Weissella sp. at 48 hours, and antibiotics (positive control) Results: The results obtained in the bacteriocin test from Weissella showed that there were differences in the inhibition zones formed, in Shigella sp the average values of the inhibition zones formed were W24 (24.4 mm), W48 (13.2 mm) and Cotrimoxazole (42.2 mm). while in Salmonella sp the average value of the inhibition zone formed is W24 (24.2 mm), W48 (12.8 mm) and Chloramphenicol (45 mm). Conclusion: Bacteriocins from LAB cincalok have an antibacterial effect on the growth of Shigella sp and Salmonella sp bacteria.
