Findings – This research shows how the learning process occurs in individuals based on generative learning theory. In addition, this study also reveals several learning strategies based on generative learning theory, including learning through summarizing, learning through mapping, learning through drawing, learning through imagining, and learning through teaching. Research Implications/Limitations – The results of this study can be used as a reference for teachers who want to implement learning strategies that can involve students’ cognitive aspects to produce more meaningful learning achievements. Originality/value – The results of this study provide educators with insight into how information processing occurs in a person’s cognition and uncover several learning strategies that align with information processing theory

Principles of Online Learning Assessment: A Literature Review Between Western Education Theory and Islamic Education Theory

Purpose – The right assessment strategy can reduce the number of academic dishonesties during online learning in the pandemic era. Academic dishonesty is a problem considered normal but has a detrimental impact on the development of a nation. Therefore, instructors need to know the principles of assessment that can reduce the number of academic dishonesties in universities. Design/methods/approach – This study uses a qualitative approach with a literature study technique. This literature comes from several online assessment books, articles, handbooks, and others. The procedure used in this study involves selecting a topic, developing themes, selecting problems, searching for literature in the database, and selecting and evaluating literature based on these problems. Findings – The results of this study are in the form of online learning assessment principles that can be applied in designing assessment activities. First, design a student-centered assessment that includes self-reflection. Second, design and include grading rubrics for assessing contributions to the discussion and assignments, projects, and the collaboration itself. Third, include collaborative assessment. Fourth, encourage students to develop skills in providing feedback. Fifth, use assessment techniques appropriate to the context and learning objectives. Sixth, design an assessment that is clear, easy to understand, and guaranteed success in the online environment. Seventh, ask students for input on how the assessment is carried out. Research implications – This study contributes to the development of literature regarding the online learning assessment process, especially in universities. Originality/value – Future research should be able to test these online learning assessment principles to find empirical evidence of their effectiveness

Uji Kekerasan Resin Komposit Olahan Sendiri dengan Filler Hidroksiapatit dari Tulang Ikan Air Tawar

Resin composite is one of the restoration materials used in dentistry. The study toward resin composite was being done to improve mechanical properties and the biocompatibilities, one of the ways  by using hydroxyapatite filler. State of the aim of this study was to evaluate the hardness number of resin composite with hydroxyapatite filler from fresh water fish bones. The study was true experimental using five samples of resin composites processed with hydroxyapatite filler from fresh water fish bones and five samples of  fabricated resin composites (GC Solare P) as a  control. Hardness was evaluated using the Vickers microhardness testing machine (Leco). The average hardness number of resin composite processed was 18.384 VHN and resin composite made by factory was 27.952 VHN. The results were analyzed statistically by t independent (α=0.05) and showed significantly difference between resin composite processed with hydroxyapatite filler from fresh water fish bones compared to fabricated resin composite. The conclusion from this study showed that the hardness number of resin composite processed with hydroxyapatite filler from fresh water fish bone is lower than fabricated resin composite

α-Mangostin hydrogel film with chitosan alginate base for recurrent aphthous stomatitis (RAS) treatment: study protocol for double-blind randomized controlled trial

Background: Recurrent Aphthous Stomatitis (RAS) is a common ulcerative disease of the oral mucosa which is characterized by pain, and recurrent lesions in the oral cavity. This condition is quite painful, causing difficulty in eating, speaking and swallowing. Topical medications have been used for this condition, but the obstacle in using topical medications is the difficulty of achieving drug effects due to saliva wash out. This problem can be overcome by film hydrogel formulation which can protect the ulcer and reduce the pain to some extent. α-mangostin is a xanthone isolated from the rind of the mangosteen fruit. One of the activities of α-mangostin is anti-inflammatory effects, which operate through the characteristic mechanism of inhibiting the inflammatory response. This protocol study aims to investigate the efficacy of an α-mangostin hydrogel film with a chitosan alginate base for recurrent aphthous stomatitis (RAS) in comparison with a placebo over a period of 7 days.Study design: This is a two-arm, double blinding, randomized controlled trial enrolling patients with RAS. The efficacy test of α-mangostin Hydrogel Film will be tested against the placebo. Patients with RAS will be allocated randomly into the two arms and the hydrogel film will be administered for 7 days. The diameter of ulcer and visual analog scale (VAS) score will be used as the primary efficacy endpoint. The outcome measure will be compared between the two arms at the baseline, day 3, day 5, and at the end of 7 days.Discussion: The purpose of this clinical research is to provide scientific evidence on the efficacy of α-mangostin hydrogel film with a chitosan alginate basis in treating recurrent aphthous stomatitis. The trial is expected to improve our capacity to scientifically confirm the anti-inflammatory effectiveness of α-mangostin compounds in a final formulation that is ready to use.Trial registration: NCT06039774 (14 September 2023)

Bioactive Carbonate Apatite Cement with Enhanced Compressive Strength via Incorporation of Silica Calcium Phosphate Composites and Calcium Hydroxide

Carbonate apatite (CO3Ap) is a bioceramic material with excellent properties for bone and dentin regeneration. To enhance its mechanical strength and bioactivity, silica calcium phosphate composites (Si-CaP) and calcium hydroxide (Ca(OH)2) were added to CO3Ap cement. The aim of this study was to investigate the effect of Si-CaP and Ca(OH)2 on the mechanical properties in terms of the compressive strength and biological characteristics of CO3Ap cement, specifically the formation of an apatite layer and the exchange of Ca, P, and Si elements. Five groups were prepared by mixing CO3Ap powder consisting of dicalcium phosphate anhydrous and vaterite powder added by varying ratios of Si-CaP and Ca(OH)2 and 0.2 mol/L Na2HPO4 as a liquid. All groups underwent compressive strength testing, and the group with the highest strength was evaluated for bioactivity by soaking it in simulated body fluid (SBF) for one, seven, 14, and 21 days. The group that added 3% Si-CaP and 7% Ca(OH)2 had the highest compressive strength among the groups. SEM analysis revealed the formation of needle-like apatite crystals from the first day of SBF soaking, and EDS analysis indicated an increase in Ca, P, and Si elements. XRD and FTIR analyses confirmed the presence of apatite. This combination of additives improved the compressive strength and showed the good bioactivity performance of CO3Ap cement, making it a potential biomaterial for bone and dental engineering applications
