Provision of appropriate learning strategies will be able to improve concepts understanding and applications of graphic design concepts. This study aimed to determine the effect of Collaborative e-learning support strategies for a classroom and self-regulated learning (SRL) outcomes and concepts application. Data analysis was performed with the MANOVA statistical test. The results of the study concluded: (1) There is a significant difference in the learning outcomes of concepts understanding between students who implemented the Collaborative e-learning (CeL) strategy and students who implemented the Collaborative Non e-learning (CNeL) strategy (p = 0.000). (2) There is a significant difference in the learning outcomes of the concepts application between students who apply CeL strategies and students who apply CNeL strategies (p = 0.000). (3) There is a significant difference in the learning outcomes of concepts understanding between students who have high and low SRL (p = 0.049). (4) There is a significant difference in the learning outcomes of concepts application between students who have high and low SRL (p = 0,000). (5) There is an interaction between the CeL strategy and the CNeL strategy with high and low SRL towards the concepts understanding learning outcomes (p = 0.002). (6) There is no interaction between the CeL strategy and the CNeL strategy with high and low SRL to the learning outcomes of the concepts application (p = 0.761). The use of CeL strategies can improve SRL of understanding graphic design concepts and application. In building the ability to understand and apply graphic design concepts in the Mathematics Education Study Program, the application of CeL strategies in this study is better than CNeL strategies in terms of improving the application ability of students' mathematics learning concepts
Response surface methodology was used to determine for optimum processing condition that yield maximum water loss and weight reduction and minimum solid gain during osmotic dehydration of radish in salt solution. The experiments were conducted according to Box-Behnken Design. The independent process variables for osmotic dehydration were processing time (30-120min), temperature (40-60°C) and salt concentration (6-10%w/w). The osmotic dehydration process was optimized for water loss, solid gain, and weight reduction. The optimum conditions were found to be; temperature = 44.575°C, immersion time =30min, salt concentration =6%. At this optimum point, water loss, solid gain and weight reduction were found to be (27.87g/100g initial sample), (1.05g/100g initial sample) and (26.83 g/100g initial sample), respectively
Nowadays, the study on fluid flow over bluff bodies is utmost important and as a fundamental topic in fluid mechanics. Generally, when a bluff body is immersed in a fluid flow, a strong tonal noise or whistle-liked noise will produce. This sound is known as Aeolian tones. This study will investigate the Aeolian tones radiated by flow past two square cylinders in a tandem arrangement. Two rigid flat plates placed in the wake of two square cylinders are investigated numerically at Reynolds number of 150, 500, 1000, 2500 and 5000. Computational Fluid Dynamic (CFD) with ANSYS Software is used to do the simulation. Two types of flow are observed at different Reynolds numbers. At low Reynolds number, the vortex formation easily occurs. Typically, the Von Karman Street Vortex is more clearly observed in low Reynolds number. At high Reynolds number, the characteristic of the flow propagation shows similar patterns. Less entrainment of the flow occurred and the vortex is reattached together formed a streamline at high Reynolds number. The sound produced is measured by using the acoustic power level. The higher the Reynolds number, the higher the sound occupied at the vicinity of the cylinders. The maximum acoustic power level is 42.7 dB which occurred at gap length G=3.0 D
Surface roughness is an important parameter determining the quality of machine elements, with the desire to reduce surface roughness to increase the quality of the product. This paper uses the experimental design method of Taguchi in combination with genetic algorithm (GAs) to study the optimization of surface roughness of machine elements when external cylindrical grinding 9CrSi steel. The smallest surface roughness achieved is Ra = 0.258261 m when feed rate Sd = 0.3 m/min, the rotation speed of the workpiece nw = 100 rpm, and the depth of cut t = 0.005 mm
This research examines the degradation of lignin by photocatalytic activity from oil palm empty fruit bunches (OPEFB) by the FeTiO3.TiO2/Ti reagent. This reagent was synthesized by the dissemination of the liquid phase by TTIP and Fe (NO3)3 prepared by the sol-gel technique utilizing acetylacetonate, acetic acid, and ethanol. Then, its morphology and structure are characterized via scanning electron microscopy energy dispersive (SEM-EDX) and X-ray diffraction (XRD). The outcomes found that FeTiO3.TiO2/Ti and TiO2/Ti reagent crystals consisted of anatase TiO2 phases. Though, FeTiO3.TiO2/Ti reagent performed well against degradation of lignin under the treatment of visible light with a degradation proportion of 64.26% in 50 minutes. The high photocatalytic activity of this reagent occurs for the least number of Fe ions, producing a duping effect in separating photogeneration holes and electrons
