Hydroxyapatite (HAp) is a biomaterial containing calcium phosphate with the chemical formula which is similar to the structure of human bone, so it is good for the purpose of healing human bones and teeth. HAp synthesis has several methods that can affect the results of HAp synthesis, such as the method of mixing CaO with phosphate, namely mixing with ultrasonic machines and magnetic stirrers. However, the discussion about the difference of HAp results with the mixing method of ultrasonic machine and magnetic stirrer is still rarely done. Therefore, it is important to examine and compare the characteristics of HAp synthesized by ultrasonic and magnetic stirrer mixing. The result of XRD test shows that HA1 has a purity of weight percentage (wt.%) of HAp crystal of 99.8%, while HA2 has a weight percentage (wt.%) of HAp crystal of 97.7%. For the FTIR test results of both specimens detected the presence of phosphate groups, and hydoxide, where both are the basic form of hydroxyapatite. Carbonate groups were also detected in the test, but it cannot be said to be bad because carbonate is a natural substitute for phosphate.

This study aims to investigate how the indigenous knowledge lexicon of Balinese undagi (traditional architects) in architecture can be transferred into visual cinematography to preserve cultural heritage, with a focus on engaging broader audiences. Employing an iconographic approach, the research analyzes the documentary Calaccitra Undagi Mahottama: Biografi I Gusti Made Gede (1843-1940) through three stages: pre-iconographic identification of visual motifs, iconographic interpretation of thematic meanings, and iconological assessment of cultural significance. Results reveal that Balinese architectural lexicons—such as Tri Mandala, Sanga Mandala, and CWSGR—are effectively abstracted into cinematic frames via intermediality, using symbolic natural imagery and spatial grids rather than physical structures to convey aesthetic and philosophical values. The study concludes that visual cinematography offers a potent medium for preserving architectural heritage by translating static spatial concepts into dynamic narratives, fostering continuity of traditional knowledge, particularly among younger generations, though its efficacy hinges on audience reception and contextual adaptation.

Grounded in cognitive neuroscience, Brain-Based Teaching (BBT) enhances science instruction by aligning classroom practices with how the brain optimally learns and processes information. This mixed-methods study investigated the effectiveness of BBT in improving Grade 8 students' conceptual understanding of Newton's Laws of Motion. Conducted in a public school in Manila, Philippines, the study involved 51 students who participated in an intervention utilizing BBT strategies, including relaxed alertness, orchestrated immersion, and active processing. Quantitative data were collected through a validated 25-item concept test, daily performance worksheets, and a Student Perception of Instruction Questionnaire (SPIQ). Qualitative data came from student journals and semi-structured interviews. Findings showed a significant improvement in post-test scores (M = 9.35), as confirmed by a paired-sample t-test (t(50) = 3.80, p < .001) and a moderate effect size (Cohen's d = 0.67). Daily worksheets consistently received "Very Good" to "Excellent" ratings. One-way ANOVA results revealed significant differences in post-test scores across prior ability levels (F(2, 48) = 10.07, p < .001, ?² = .30), suggesting that BBT's effectiveness varied depending on students' initial competence. The SPIQ survey revealed positive perceptions, with the highest mean score (3.6) indicating student satisfaction with the classroom environment and instructional support. Thematic analysis identified three key themes: enhanced instruction through various classroom activities, insightful learning, and retention of learning. Overall, BBT was found to be effective in fostering conceptual understanding and promoting a positive learning environment. Its novelty lies in highlighting the differentiated impact of BBT based on prior achievement in a resource-constrained public school context.
