Abstract

Assessment based on Higher Order Thinking Skills (HOTS) plays a strategic role in chemistry learning because it encourages students to think critically, analytically, and creatively. These abilities are essential for connecting chemical concepts with real-life contexts, as well as preparing students to face the challenges of the global era and advancements in science. To formulate appropriate and evidence-based assessment strategies, an in-depth review through a Systematic Literature Review (SLR) is necessary. SLR is a method of literature review that is systematic, objective, and structured to identify trends, research gaps, and relevant empirical evidence. This review focuses on the implementation of HOTS-based assessment, particularly in the development of assessment instruments. The results show that the most commonly used instruments in HOTS-based assessment are test-based assessments, especially in the form of essay and multiple-choice questions. These findings serve as a crucial foundation for designing and developing more effective and contextual chemistry assessment practices.

Abstract

This study aims to examine the effectiveness of the Team-Assisted Individualization (TAI) cooperative learning model in improving the learning outcomes of Grade XI students on hydrocarbon material at State Senior High School 2 Dumai. The research employed a randomized control group pretest-posttest design, involving two groups selected randomly, an experimental group that applied the TAI model and a control group that used discussion-based learning. A test on hydrocarbon concepts was administered to both groups before and after the treatment to measure student performance. The data were analyzed using a t-test at a 0,05-significance level. The results showed that the calculated t-value of 5,24023 exceeded the t-table value of 1,6664, indicating a significant difference in learning outcomes between the two groups. These findings suggest that the cooperative learning type of the Team Assisted Individualization is more effective in enhancing the learning outcomes of students compared to the discussion method previously used in the class.

Abstract

This study was motivated by the low level of students' critical thinking skills, which is evident from their difficulties in solving complex problems. Students tend to rely on memorized formulas rather than analyzing the problems beforehand. The objective of this study was to investigate the improvement of students’ critical thinking skills on the topic of ionic equilibrium and buffer solution pH in Grade XI at SMAN 2 Tambang, through the implementation of the Predict-Observe-Explain (POE) learning model. The research was conducted in the even semester of the 2024/2025 academic year using a randomized control group pretest-posttest design, involving two classes: class XI-1 as the experimental group and class XI-4 as the control group. Data collection was carried out using pretest scores as baseline data for normality and homogeneity tests, and the difference between pretest and posttest scores was used for hypothesis testing. Data analysis techniques included normality tests, homogeneity tests, and hypothesis testing. The results indicated that students’ critical thinking skills improved significantly after the application of the POE model. This improvement was confirmed by the hypothesis test, where the significance value was 0.000 < 0.05, indicating that H₀ was rejected and Hₐ was accepted. Therefore, the implementation of the POE learning model is recommended as an effective alternative to enhance students’ critical thinking skills, particularly in learning materials related to ionic equilibrium and buffer solution pH.

Abstract

Microcrystalline cellulose (MCC) is a partially depolymerized cellulose derivative obtained through the hydrolysis of α-cellulose. However, MCC has limitations in drug delivery systems, particularly for poorly water-soluble (hydrophobic) drugs; therefore, MCC modification is required to improve the loading and delivery efficiency of such compounds. This study aimed to modify MCC produced from the hydrolysis of Liberica coffee husk cellulose to enable its application as a carrier for hydrophobic drugs. The modification was carried out using saponins, followed by dexamethasone loading into MCC–saponin and unmodified MCC using ethanol as the solvent, with incubation for 24 h. The MCC–saponin system exhibited a substantially higher dexamethasone loading capacity (23.436 mg/g) than unmodified MCC (6.768 mg/g). In vitro drug release results further showed that dexamethasone release from MCC–saponin increased within 60–180 min.

Abstract

Global population growth has driven increased demand for energy, particularly fossil fuels. A sustainable alternative to address this issue is the production of biodiesel from renewable sources, such as waste cooking oil. This study utilized a heterogeneous potassium oxide (K₂O) catalyst derived from local Trenggalek durian peel ash to enhance the efficiency of the transesterification reaction. The catalyst was synthesized via calcination at 400°C, 500°C, and 600°C for 5 hours. The transesterification reaction was carried out with a methanol-to-oil molar ratio of 12:1 and catalyst concentrations of 1%, 3%, and 5% (w/w) at 65°C. The optimum condition was achieved using durian peel ash catalyst calcined at 600°C at a concentration of 3% (w/w), yielding a biodiesel conversion of 96.24% via ultrasonic-assisted transesterification. The physicochemical characterization of the produced biodiesel showed results that met standard specifications, including analyses of yield, density, viscosity, refractive index, acid value, saponification value, and iodine value. Furthermore, FT-IR and GC-MS analyses were performed to confirm the functional groups and components of the biodiesel product, in accordance with the expected specifications.
