Erwin edyansyah, Dian Adhe Bianggo Naue, Asrori — Wed, 30 Sep 2026 00:00:00 +0000

Abstract

Background: Sabouraud Dextrose Agar (SDA) is a standard medium widely used for the isolation and growth of fungi. However, its relatively high cost and reliance on commercial media have encouraged the development of alternative media based on natural ingredients. Soybeans (Glycine max (L.) Merrill) have a high protein and carbohydrate content, making them a potential source of nutrients in fungal culture media. Objective: This study aims to determine the potential of soybeans (Glycine max (L.) Merrill) as an alternative culture medium for the growth of Candida sp. Method: This study used a quasi-experimental method. The culture medium was made from soybeans with varying concentrations of 10%, 20%, 30%, 40%, 50%, and 60%. Each medium was inoculated with Candida sp. isolates and incubated at 28–30°C. Results: The diameter of the colonies formed increased gradually, from 1.4 mm at a concentration of 10% to 2.6 mm at a concentration of 60%. Increasing the concentration of soybean extract was followed by an increase in colony diameter. Conclusion: Soybean (Glycine max (L.) Merrill)-based media can support the growth of Candida sp. Thus, soybean media have the potential to be a more economical alternative culture medium, although further development and standardization are required to match the performance of Sabouraud Dextrose Agar.

Determining the Optimal Flotation Time for Enhanced Detection of Ascaris lumbricoides Eggs in Fecal ExamINATION

Dian Adhe Bianggo Naue NAUE, Erwin Edyansyah — Wed, 30 Sep 2026 00:00:00 +0000

Microscopic examination of fecal specimens using the flotation method has higher sensitivity than direct smear and sedimentation methods. Centrifugal flotation enables the detection of a greater number of helminth eggs and reduces the likelihood of false-negative results by facilitating the rapid sedimentation of interfering particles. The use of a saturated sucrose solution also provides a cleaner and clearer microscopic background. This study was conducted using fecal specimens containing Ascaris lumbricoides eggs to determine the optimal flotation time for recovering the highest number of eggs. Three positive fecal specimens were examined using centrifugal flotation with flotation times of 20, 30, and 40 minutes, each performed in five replicates. The recovered flotation layer was examined microscopically, and the number of Ascaris lumbricoides eggs was counted and averaged. Data were analyzed using the Shapiro–Wilk normality test followed by a one-way analysis of variance (One-Way ANOVA). The mean egg counts were 118 eggs at 20 minutes, 162 eggs at 30 minutes, and 134 eggs at 40 minutes of flotation. The One-Way ANOVA revealed a statistically significant difference among the flotation times (p = 0.000, α = 0.05). Variations in flotation time using the centrifugal flotation method significantly affected the number of Ascaris lumbricoides eggs recovered. Therefore, laboratory personnel are recommended to use a flotation time of 30 minutes with saturated sucrose solution when performing the centrifugal flotation method to achieve optimal egg recovery.

Mardyana Nizar, Trisna Citra — Wed, 30 Sep 2026 00:00:00 +0000

Urine erythrocyte examination is one of the important parameters in urinalysis to detect hematuria and abnormalities of the urinary system. Delays in examination often become a challenge in laboratories, as erythrocytes are prone to lysis or morphological changes that may affect result accuracy. This study aimed to determine the effectiveness of Neutral Buffered Formalin (NBF) as a fixative in maintaining the count and morphology of urine erythrocytes at different examination delay times: 0 hours as control, and delays of 3 hours and 6 hours.

Urine samples were collected using purposive sampling, and erythrocyte sediment examination was performed using a light microscope. Data analysis employed the Dependent Sample T-Test to compare results across each delay interval.

The findings showed that the use of NBF was able to maintain the stability of urine erythrocytes up to a 6-hour delay, with differences in count and morphology that were not statistically significant (p > 0.05). These results indicate that NBF is effective as a fixative to preserve the quality of urine erythrocyte examination despite delays in analysis.

Wed, 30 Sep 2026 00:00:00 +0000

Hypertension remains a major contributor to cardiovascular morbidity, yet community screening often relies on late or opportunistic measurements. This study compares Logistic Regression, Random Forest, Gradient Boosting, XGBoost, and Support Vector Machine for hypertension risk prediction using a public dataset of 1,985 patient records and ten demographic, clinical, and lifestyle predictors. Numerical features were standardized, categorical features were one-hot encoded, and missing medication values were imputed using the mode. Models were evaluated using an 80:20 stratified train-test split and 5-fold cross-validation. The best model was optimized with RandomizedSearchCV and examined through feature importance and ablation study. Tuned Gradient Boosting achieved the highest cross-validation F1-score of 0.9994 and ROC-AUC of 1.0000. On 397 test records, it obtained 0.9975 accuracy, 1.0000 precision, 0.9951 recall, 0.9976 F1-score, and 1.0000 ROC-AUC, with only one false negative. Ablation showed that removing blood pressure history reduced test F1-score to 0.7681, confirming its dominant contribution. The model is promising for screening support, but external clinical validation is required before diagnostic use.

Reslisa Lisnawati, Rio Purnama — Wed, 30 Sep 2026 00:00:00 +0000

The American cockroach, Periplaneta americana, is a pest that can potentially contaminate food and the environment, making its control important in environmental health. The use of plant-based materials with repellent activity may provide an approach to cockroach control. This study aimed to analyze and compare the effectiveness of kaffir lime (Citrus hystrix) and Indonesian bay leaf (Syzygium polyanthum) powders as natural repellents against P. americana. A true experimental study with a post-test only control group design was conducted. Powders of both leaves were tested at doses of 7, 9, and 11 g, with a 0 g control, using six replicates and 10 cockroaches in each experimental unit. Repellent responses were observed for one hour. Active-treatment data were analyzed using two-way ANOVA followed by Tukey's HSD test at α=0.05. The mean repellent responses of C. hystrix at 7, 9, and 11 g were 7.17, 7.67, and 9.17 cockroaches, respectively, compared with 5.00, 6.00, and 6.50 cockroaches for S. polyanthum. Plant powder type (F=51.735; p<0.001) and dose (F=11.327; p<0.001) significantly affected the repellent response, whereas their interaction was not significant (p=0.410). Tukey's HSD test showed a significant difference between the 7 and 11 g doses (p=0.015). C. hystrix powder produced a higher repellent response than S. polyanthum, with the highest response observed at 11 g. Both plant materials have potential for development as botanical repellents against P. americana.

erna setyaningsih, Rizqitha, Diah Widyatun, Mariza Mustika Dewi — Wed, 30 Sep 2026 00:00:00 +0000

Background: The prevalence of sleep problems in Indonesian children aged 0-36 months is quite high (31%). Babies experiencing sleep disorders with symptoms of frequently waking up at night occur in Indonesia at around 44.2%. However, it is estimated that more than 72% of parents do not consider sleep disorders in babies to be a problem. In fact, sleep disorders can interfere with the baby's growth, make the body's immune function vulnerable, and disrupt the regulation of the endocrine system. Sleep disorders in babies are recommended for non-pharmacological treatment, namely skin to skin contact which can improve the quality of the baby's sleep. Objective: The aim of this research is to determine the effect of skin to skin contact on the sleep quality of babies aged 0-6 months. Method: This research uses a pre-experimental method using one group pre-test and post-test. The research sample used an accidental sampling technique of 7 babies with sleep disorders. Results: There is an influence of skin to skin contact on baby sleep quality with a p value of 0.012 (<0.05). The average quality of baby sleep before being given skin to skin contact was 2.50 and the average after being given skin to skin contact was 1.30. Conclusion: There is an influence of skin to skin contact on the quality of baby's sleep. Babies who experience sleep disorders after being given skin to skin contact using the kangoroo method become calmer and fall asleep easily. This allows the baby to be in a stable state in the mother's arms and avoid negative emotions that make the baby fussy. So that the baby can sleep comfortably and calmly in the mother's arms.
