Emulsifier as the mixture of monoglycerides (MG) and diglycerides (DG) is widely used in the food industry such as bakery products, margarines, dairy products, and confectionary. This emulsifier can be produced by glycerolysis of fatty acids using acid catalyst. In this work, natural deep eutectic solvent (NADES) was chosen as a catalyst in the glycerolysis of stearic acid due to greener and sustainable catalyst with advantages such as low vapor pressure, non-toxic, biodegradable, and easy to reuse. The catalytic activity of the NADES, kinetic constants and activation energies for the reaction were investigated. The reaction was carried out at agitation speed (300 rpm), catalyst concentration (5 wt%), reaction temperatures (120 °C, 150 °C and 180 °C) and reactant mole ratios (1:2, 1:4 and 1:6). Choline chloride-sorbitol NADES has highest catalytic activity on the glycerolysis of stearic acid. The kinetic calculation results using choline chloride-sorbitol NADES as a catalyst validated that the reaction was pseudo second order with an activation energy of 64.04 kJ∙mol−1, and a collision factor of 196,696 L∙mol−1∙min−1. This kinetics data will be useful for reactor design in industrial applications.

Abstract Trypanosoma evansi is reportedly divided into two genotypes: types A and B. The type B is uncommon and reportedly limited to Africa: Kenya Sudan, and Ethiopia. In contrast, type A has been widely reported in Africa, South America, and Asia. However, Trypanosoma evansi type non-A/B has never been reported. Therefore, this study aims to determine the species and genotype of the Trypanozoon subgenus using a robust identification algorithm. Forty-three trypanosoma isolates from Indonesia were identified as Trypanosoma evansi using a molecular identification algorithm. Further identification showed that 39 isolates were type A and 4 isolates were possibly non-A/B types. The PML, AMN-SB1, and STENT3 isolates were likely non-A/B type Trypanosoma evansi isolated from buffalo, while the PDE isolates were isolated from cattle. Cladistic analysis revealed that Indonesian Trypanosoma evansi was divided into seven clusters based on the gRNA-kDNA minicircle gene. Clusters 6 and 7 are each divided into two sub-clusters. The areas with the highest genetic diversity are the provinces of Banten, Central Java (included Yogyakarta), and East Nusa Tenggara. The Central Java (including Yogyakarta) and East Nusa Tenggara provinces, each have four sub-clusters, while Banten has three.

Sustainable aquaculture is crucial for environmental and economic stability in tropical regions. JICA tilapia (Oreochromis sp.) aquaculture development in Sumatran peatlands requires sustainable fry. This study aimed to analyze the optimal egg density to maximize larval production in a controlled hatchery environment. Utilizing a randomized experimental approach, we obtained eggs from naturally spawned tilapia, hatched in a funnel container (top diameter 30 cm; bottom diameter 15 cm; height 50 cm; water volume 10 L) within a 5 x 10 x 1 m3 tub filled with 90 cm of water using a recirculation system. We compared two densities: 2,000 eggs/L water and 3,000 eggs/L water. The findings of our study indicate that the difference in hatching rate between egg densities of 2000 eggs/L and 3000 eggs/L was not significant at the 95% confidence level (p> 0.05). Increasing the egg density to 3000 eggs/L does not significantly reduce the hatching rate, making it possible to consider higher densities without significant risks to larval production. This offers a model that can be replicated in similar tropical peatland environments.

Human resources that can face the challenges of increasingly rapid and dynamic development must have high intellectual skills. High intellectual skills are characterized by critical thinking skills, creativity competitiveness, and the ability to communicate ideas and solve any problems. Intellectual skills, especially critical thinking skills, are the demands of human resources in the 21st century. In recent years, the development of critical thinking skills-based research has been rapid. Critical thinking skills research has produced many theoretical and empirical findings. Many trends and issues have emerged, proving the complexity and dynamics of critical thinking skills research. This study aims to provide an overview of the latest research on critical thinking skills. The development of recent research on critical thinking skills in recent years can be illustrated through a bibliometric approach. The bibliometric approach was applied to uncover the most common keywords and terms and their interactions through compound word analysis. The Scopus database was selected for the period 2011 to 2021; 2,855 documents were obtained, and then the publications each year, the most researched topics, and the development of interest in these topics were identified. The research results show that from 2011 to 2020, there was a significant increase in research on critical thinking skills, while there was a decline from 2020 to 2021. Research topics that are closely related to critical thinking skills are higher-order thinking skills. The topic of critical thinking has a close relationship with education, curriculum, and educational measurement. Research on critical thinking skills with innovative learning models, such as inquiry learning and discovery learning models, has not been widely studied. Even though a lot of research on critical thinking skills has been carried out, there is still a need to develop research on critical thinking skills in various frameworks.

Turtles are one of the fauna that is threatened with extinction. The cause of its extinction is inadequate management of conservation techniques. The Lantera Trenggalek Community sees the problem of the high operational costs of turtle conservation faced by the people of Masaran Village, Trenggalek, East Java. The operational costs of turtle conservation are high, including the costs of turtle feed, turtle maintenance and the electricity costs for turtle egg incubators reaching 1800 watts, so they require high PLN electricity. Therefore, this research aims to innovate to overcome partner problems by utilizing off grid PLTS using Bidirectional Buck and Boost Converter. The aim of using PLTS in Masaran village is to increase the availability of electricity sources at relatively low prices. However, in the PLTS implementation system, the electrical energy produced is unstable. So the PLTS system is equipped with batteries to store energy. The energy storage process requires a converter which functions to stabilize the output voltage of the PLTS. This research used Bidirectional Buck and Boost Converters because these converters are able to work in two directions so they can optimize the output voltage from PLTS. The results of testing the PLTS system with Bidirectional Buck and Boost Converter show that when in buck mode, the converter output voltage can reach 14.4V which is used for battery charging. The output of this research is that the Off Grid PLTS system can produce maximum electrical energy so that it can overcome partner problems in increasing the turtle population.

The intricacy of real-world challenges in project-based geoscience learning is complex to assess with a STEM approach; hence, research into an effective model is necessary to address current issues in education. Understanding the role of STEM in resolving challenging real-world issues requires integrating STEM literacy that is appropriate for geoscience education. This study examines the effectiveness of the Project-Based Geoscience Learning (PJBGL) model in enhancing STEM literacy. By integrating project-based learning with geoscience, the aim is to create an interactive and immersive learning environment. The study seeks to contribute to knowledge about the effectiveness of this model compared to the conventional model. The aim was to evaluate the PJBGL model's impact on students' literacy, particularly in the geosciences. The study utilized a pretest-posttest control group design with 33 students, 19 in the experimental group and 14 in the control group, collecting STEM literacy data using a test instrument and analyzing the data with the Mann-Whitney test. Effect Size calculation using Cohen's d and increased STEM literacy was tested with the N-Gain formula. The research results show that the PJBGL model is more effective in increasing STEM literacy in geoscience learning than the conventional learning model. This finding holds implications for educators and curriculum developers seeking innovative strategies to cultivate students' STEM literacy

Bordetella pertussis infection is a highly contagious respiratory disease that can cause complications such as pneumonia and death. A total of 62,646 cases of pertussis worldwide were reported by WHO in 2022. This study aimed to obtain the pertussis seroprevalence and sociodemographic data in children aged 1–14 years and its association factors in the community based on Riskesdas 2013 and 2018. Bivariate and multivariate analysis was carried out on data from 12,753 children aged 1–14 years collected from Riskesdas 2013 and 2018 in Indonesia. Pertussis serology data was obtained based on the results of the ELISA examination which was categorized as seropositive if anti-pertussis toxin IgG ≥ 100 IU/mL or anti-pertussis IgG > 11 NTU. Pertussis seropositive indicated recent pertussis infection if no pertussis vaccine was received within the last twelve months. Pertussis seroprevalence was found at 9.8% and 33.4% in Riskesdas 2013 and 2018 respectively. While 10.1% of children aged 5–14 years were found pertussis seropositive by excluding the possible effect of vaccination in the last twelve months in Riskesdas 2013. The most important associated factor in seropositive pertussis at ages 1–4 years and 5–14 years was a history of pneumonia in the last month (OR = 2.709, 95%CI: 2.592–2.831 in Riskesdas 2013 and OR = 2.421, 95%CI: 2.299–2.550 in Riskesdas 2018). In the adjusted analysis for respondents' characteristics, low maternal education was the predictive factor that most influenced pertussis seropositivity, especially in the 2013 Riskesdas (APOR = 2.983, 95%CI: 2.670–3.333). In conclusion, the results of this study showed that the seroprevalence of pertussis was high, especially in children aged 5–14 years, so that pertussis vaccine booster administration could be considered. Because the most influencing factor towards pertussis seropositive was low maternal education, the groups of children with low-educated mothers should be targets for strengthening complete vaccination coverage and disease control.
