Abstract

This research aims to analyze the increase in biodiversity literacy skills based on learning methods and level of education. Apart from that, this research also analyzes indicators of biodiversity literacy. The research analyzed 8 reputable international journals with 6 learning methods, 4 levels of education, and 10 biodiversity literacy assessment indicators. The research was carried out with meta analysis in the form of effect size analysis using the OpenMEE application. The research results stated that, based on the analysis of 8 reputable international journals, the estimated Effect Size (ES) value was 0.357 in the medium category (0.2 ≤ ES ≤ 0.8) and the p-Value < 0.001. Meanwhile, heterogeneous analysis shows that the Tau^2 value is 0.127 with an I^2 of 89.434, meaning that the diversity of variance from the journal studies analyzed has a very significant effect. Meanwhile, the results of the effect size analysis based on the learning model stated that there were 3 learning methods that obtained an estimated Effect Size (ES) value in the high category, including: Green Learning Method (GeLem) obtained an estimated effect size value of 3.797, a learning method based on local wisdom obtained a value The estimated effect size was 1.665, and the Virtual Field Trip assisted by Augmented Reality obtained an estimated effect size value of 0.974. Furthermore, the results of the effect size analysis of biodiversity literacy abilities at various levels of education stated that high school students had higher biodiversity literacy abilities compared to other levels of education, namely 1.281 in the high category (ES ³ 0.8). This research also analyzes the effect size value based on biodiversity literacy indicators. Based on 10 biodiversity literacy indicators, only one indicator shows the highest estimated effect size value compared to other indicators, namely the environmental knowledge indicator of 1.813. Thus, it can be concluded that there is a significant influence in increasing biodiversity literacy skills based on learning methods and level of education.

Abstract

Diabetes Mellitus (DM) is a global epidemic with high morbidity and mortality. Diabetes Mellitus (DM) is thought to have a negative impact on sperm quality. Yellow pumpkin contains antioxidants that can neutralize free radicals which can improve fertility. Glucomannan is a substance contained in porang which functions as a soluble fiber and plays a role in blood glucose balance. This study aims to examine pumpkin flour, porang flour and a combination of both flours on sperm motility and body weight of alloxan-induced diabetic mice. This study used 25 mice aged 3 months, body weight 25gr-30 gr. This study used a completely randomized plan (CRD) with 5 replications and 5 treatments. The treatments were negative control (diabetic mice), positive control (administration of glimepiride at a dose of 0.0078 mg/mice per day), D1 (pumpkin flour 134.4 mg/30g BW of mice), D2 (porang flour 63mg/30g BW mice), D3 (combination 50% : 50% = 67.2 mg : 31.5 mg/30 grBW mice). Diabetic mice were made by intraperitoneal induction of alloxan dose of 200 mg/Kg for 3 days. The parameters observed were spermatozoa motility, body weight and blood sugar levels of the mice. The research data were analyzed using the ANOVA test followed by the BNT test. The results showed that the administration of glymeride, pumpkin flour, porang flour and their combination had a significant effect on reducing blood sugar (p=0.000) and sperm motility (p=0.000), but had no effect on body weight (p=0.317). Conclusion: pumpkin flour, porang flour or a combination of both flours can be used as herbs to lower blood sugar and increase sperm motility in diabetes sufferers.

Abstract

The issue of sanitation and water pollution due to fecal waste has become a serious concern in Indonesia, particularly after it was revealed that approximately 70% of the community's drinking water sources are contaminated with human feces. Determining safe waste management requirements necessitates indicators confirming the contamination-free nature of the waste management methods. Pathogen testing indicators for fecal waste are highly diverse. The current standard testing is the culture-based method for microorganisms and microscopy observation for helminths. However, molecular detection tools for these pathogens can give higher sensitivity and specificity in a relatively shorter time of technical processing. In this research, we designed primers for molecular-based diagnostics on three pathogens exhibiting extreme survival capabilities under various environmental conditions. The species-coupled genes are AmpC for Escherichia coli, AAC for Mycobacterium tuberculosis, and RNR3 for Ascaris lumbricoides. The design of molecular-based biomarkers and their specificity tests were conducted using web-based bioinformatics programs to prevent unintended dimers. Ultimately, primers were validated by conventional gradient PCR on available positive controls and a sample from processed fecal sludge. The PCR validation test showed that the designed primers were validated to amplify the intended target with the right size without unspecific bands on the positive controls. Meanwhile, the AAC gene for E. coli was detected in the sample from the fecal sludge.
