Abstract

This study looks into how well flipcharts and the circuit learning model might improve scientific learning results and cooperative attitudes in Indonesian elementary school students. In order to address the widespread problem of low educational quality, the research proposes a novel method of instruction. The underutilization of engaging media in scientific education is the research gap, and the uniqueness is in suggesting the circuit learning model with flipcharts as a possible solution. The study used the independent sample t-test as a quantitative method for assessing hypotheses. The experimental group outperformed the control group in terms of learning outcomes, according to the statistical results. The findings of the t-test (p < 0.05) attest to the effectiveness of the circuit learning model utilizing flipcharts in improving science learning. In particular, there was an increase in student involvement, attention span, and general learning activities when flipchart media was used. These statistical results offer empirical backing for the suggested intervention, indicating that it has the capacity to close the noted research gap and improve students' academic and social learning experiences. The statistically significant findings of this study suggest that teachers should think about implementing the circuit learning model with flipcharts as a successful tactic to enhance scientific teaching outcomes

Abstract

This study explores the effects of incorporating palm oil fuel ash (POFA) and fly ash (FA) as partial cement substitutes on the mechanical properties and characteristics of high-quality mortar, specifically Engineered Cementitious Composites (ECC). ECC mortar was fabricated by milling POFA waste and FA through a top-down method utilizing a ball mill. The resulting material was subjected to tests for slump flow, water absorption, compressive strength, and characterized through XRF, FTIR, SEM/EDX, and XRD analyses. FTIR analysis verified the existence of Si-O and Al-O groups within the composite made of POFA-FA ECC. XRF analysis of FA and POFA showed cementitious properties, with SiO2+Al2O3+Fe2O3 exceeding 50% and CaO surpassing 10%. SEM and XRD results indicated minimal cavity formation, suggesting a high compressive strength in the mortar. Particle size distribution analysis revealed prevalent particles in the 1.5×10−1 to 2.0×10−1 μm range. The compressive strength test after 28 days, incorporating 15% FA and 10% POFA, yielded the highest strength at 59.30 MPa. The water absorption values ranged from 1.25% to 2.67%, indicating that POFA-FA assists in the cement hydration process and also serves as a filler. As a result, the material’s density is very high, leading to fewer voids formed, thus reducing the trapped water, which significantly affects the mortar’s strength.

Abstract

Titanium dioxide (TiO2) is a semiconductor material that has great stability so that it can be utilized as a filler material for High Density Polyethylene (HDPE) thermoplastics. This study was conducted to determine the effect of TiO2 PEG 6000 nanoparticle filler composition on the mechanical properties of HDPE thermoplastics. TiO2 was synthesized with sol gel method and then mixed with PEG 6000. Nanocomposites are made by mixing HDPE with TiO2 nano filler in a rheomixer tool with variations in filler composition (2, 4, 6, 8, 10) %wt, then molded using injection molding tools with ASTM 638 type V standards and analyzing mechanical properties using UTM (Universal Testing Machine) test equipment which includes tensile strength, elongation at break and elastic modulus. The results of XRD analysis produced a particle size of 22nm and SEM tests showed that the surface of TiO2 nanoparticles had a smooth and even surface. The sample with 8% wt filler composition variation is the sample with the best tensile strength value of 84.72 MPa, the highest elongation at break value in the sample with 4% filler of 35.5% and the highest elastic modulus in the sample with 8%wt filler composition of 729.33 MPa.Keywords: Titanium dioxide, HDPE thermoplastic, PEG 6000, Tensile test.
