Abstract

Decimal numbers are difficult to understand by elementary school students because they consider fractions and decimals as different things. Therefore, learning decimal fractions should be associated with real experiences to make it more meaningful, one of which is through realistic mathematics education (RME) with Islamic context. This study aims to analyze students' understanding and response to RME with Islamic context by using mixed method. The population of this study were fourth grade students in one of the integrated Islamic elementary schools in Banda Aceh, Indonesia. Data collection was done through tests and interviews. The results showed that 75.56% of students had good concept understanding skills. Students experience misconceptions in sorting one-digit and two-digit decimal numbers, even though the teacher has provided illustrations in learning and students also find their own position of one-digit and two-digit decimal numbers on the scale model. Based on interviews, it was found that students were very happy in participating in mathematics learning with an Islamic context because they could get a reward (pahala) while learning mathematics reading the Qur’an and getting new knowledge such as the story of the prophet Syuaib's people, sincerity in giving, and prioritizing honesty in trading.      Keywords: concept understanding ability, realistic mathematics education, Islamic context, decimal numbers.

Abstract

2013 curriculum has mandated the importance of teachers and paying attention to aspects of diversity of students in learning, including intelligence. Based on the type of intelligence proposed by Gardner (2003), linguistic-verbal intelligence and mathematical logical intelligence are two intelligences that need to be considered by the teacher in mathematics learning, for example when the teacher prepares a mathematics learning tool. This study aimed to determine the effectiveness of mathematical learning tools based on linguistic-verbal intelligence and mathematical logical intelligence on material equations and linear inequalities. This study used the Plomp development model which consists of three phases, namely initial investigation, design, and assessment. The trial was carried out four times for students of class VII-8 in SMP Negeri 2 Banda Aceh. To determine the effectiveness of learning devices, criteria Kemp was applied, et al (1994). The results of the development showed that the mathematics learning tools based on linguistic-verbal intelligence and mathematical logical intelligence were effective. Because of that, this learning tool is worthy of being used by teachers in mathematics learning, especially in similarities material and linear inequalities.

Abstract

Malaria, caused by the Plasmodium parasite, represents a significant global health challenge, with approximately 229 million cases reported in 2020. Current treatments include artemisinin-based combination therapy; however, drug resistance poses serious issues. Natural products, including alkaloids from Sida rhombifolia, particularly cryptolepine, effectively inhibit Plasmodium falciparum through DNA intercalation. Research indicates that mutations in the PfDHFR enzyme of P. falciparum contribute to drug resistance, highlighting the urgent need for new inhibitors. A literature review combined with SwissADME, toxicology predictions, and molecular docking methods identified 11-cryptolepine carboxylic acid (B1) and N-trans-feruloyl tyramine (B11) as potential new inhibitors. The compounds exhibited binding energies of −7.22 and −8.41 kcal/mol, which are close to the native ligand (−7.31 kcal/mol). Additionally, they demonstrate favorable drug-likeness properties, indicating their potential as viable candidates for drug development. The molecular dynamics simulation for 100 ns was conducted to observe molecular interactions in a specific system dynamically. It was found that ligand B1 has better stability compared to ligand B11. This compound demonstrates significant potential for advancing malaria treatment strategies. Further research and clinical evaluation are warranted to fully realize their potential and translate these findings into effective clinical interventions for combating malaria globally.

Abstract

Tagetes erecta is one of traditional herbs with a variety of pharmacological actions. This study attempted to assess the toxicity and antidiabetic activity of T. erecta leaf extract. The extraction was carried out by maceration, then continued with phytochemical analysis. Toxicity of the extract was conducted using the brine shrimp lethality test. The antidiabetic activity was evaluated by α-amylase inhibitory using the 3,5-dinitrosalicylic acid method. The phytochemical of the most active extract was identified using GC-MS and subjected to bind the α-amylase (PDB ID: 2QV4) employing molecular docking. The LC50 values of n-hexane, EtOAc, and MeOH extracts were 33.41, 14.00, and 35.03 ppm, respectively, indicating high toxicity. The antidiabetic activity showed that EtOAc extract has the lowest IC50 value (1053.95 mg/L). Molecular docking analysis revealed the compounds 1–5 has range of binding energy at −4.07 to −4.83 kcal/mol. Acarbose as a positive control showed the lower binding energy at −5.03 kcal/mol, indicated more effective α-amylase inhibitory. This study revealed that T. erecta leaf extract has significant cytotoxic potential, which may warrant further exploration for anticancer applications. However, the relatively weak α-amylase inhibitory and lower binding affinity compared to acarbose imply limited utility as an antidiabetic agent.
