Abstract

Natural product-based noise-absorbing composite can be an alternative to replace synthetic fiber because of its advantages of high strength, toughness, low price, and abundance to reduce noise. The materials used were pineapple leaf fibers with paper waste. This research aims to study the advantage of natural products to reduce noise by analyzing the coefficient of sound absorption and impact strength to evaluate the absorbing composite. The composites were tested with the Charpy method with ISO 11654 standard and ASTM E23 for sound absorption and impact strength. Sound absorption was carried out using an impedance tube at a frequency range of 250 – 3000 Hz. The volume fraction of pineapple leaf fibers, paper waste, and resin epoxy concentrations were 20% : 30% : 50%, 25% : 25% : 50%, and 30% : 20% : 50%. The thickness for the sound absorption coefficient was 2 cm and 3 cm, while the thickness of the impact strength was 0.5 cm. The highest sound absorption coefficient of pineapple leaf fibers composite for 30% : 20% : 50% volume fraction was 0.788 for sample 2 cm. The highest impact strength for 20% : 30% : 50% volume fraction of the thickness of 0.5 cm was 3.527 J/mm2. The results of the sound absorption coefficient will increase if used more pineapple leaf fibers but it will decrease the impact strength. Based on this research, the pineapple leaf fibers will improve the quality of the composite that can be used as a sound-absorbing material as well. These materials possess the promising potential to decrease waste and are used in industries for a low cost.

Abstract

Computational physics is concerned with the application of numerical methods in solving physical problems. The van der Waals gas model is one of the most common non-linear models. This study simulated a mathematical model of a non-linear equation using MatLab for the case of the specific volume of gas in the equation of the state of van der Waals. This study aimed to determine the molar volume and compressibility factor, as well as describe the relationship between the compressibility factor and the reduced pressure. The method of the study is experimental. The independent variables are the reduced pressure and temperature values. The dependent variable is the determination of the value of the molar volume (V) and the compressibility factor (Z). The control variable, in the form of a function used in solving this case, is based on van der Waals equation with the gas used is ammonia. The fzero command can be used to solve f(x)=0 with a single variable. This program that has been running successfully can show various predictions in the form of reduction pressure, thus obtaining the values of the molar volume and compressibility factor using the ideal gas equation. There is a deviation in ammonia gas, the Z>1 at high reduction pressures and Z<1 at medium pressures. This study can provide contributions and benefits in the form of material enrichment of thermodynamics to understand how real gases behave. The ideal gas equation can be modified into the van der Waals equation.

Abstract

Feedback on formative assessment is a teacher's effort to help students with learning difficulties by responding to their evaluation results, especially on HOTS-based evaluations, which have a higher level of completion. Therefore, this study aims to determine the effect of immediate feedback on improving Material Comprehension (MC) and Learning Motivation (LM). Unfortunately, the teacher needs to provide feedback due to several factors, one of which is time constraints due to teachers’ activity. This study aims to investigate the effect of Go Formative in providing immediate feedback on formative physics assessments on material comprehension and learning motivation enhancement of 10th-grade high school students. This research is quasi-experimental with a non-equivalent control group design involving two classes, namely the control and experimental classes. The two classes were selected by employing a simple random sampling technique. This study's results show a different effect of using Go Formative in providing quick feedback in improving students' material comprehension. The existence of these differences makes the provision of quick and immediate feedback through the Go Formative website a solution to overcome the obstacles experienced by teachers in carrying out formative assessments.

Abstract

Problem-solving Skills and Reading-Writing Literacy are two necessary things students must have to compete in the 21st century. This study aims at determining the effectiveness of Problem-based Learning with Integrated Reading and Writing tasks to improve students' problem-solving and reading-writing literacy skills. A quantitative method using a quasi-experimental design with a non-equivalent control group was employed in this study. The sampling technique used in this study was the purposive sampling technique. The sample used in this study was 36 students divided into two groups: the control group and the experimental group. The instrument used in this study was a physics problem-solving skill test instrument and a reading-writing literacy instrument. The data analysis technique in this study was a quantitative analysis technique. The results showed that the N-gain value of the physics problem-solving skill test for the experimental group was 0.67 in the medium category, and the control group was 0.65 in the medium category. In the reading-writing literacy test, the N-gain value for the experimental group was 0.55 in the medium category and 0.29 in the low category for the control group. The Problem-based Learning model with Integrated Reading and Writing Tasks has little impact on improving students' problem-solving skills. However, it has a significant effect on increasing students' reading-writing literacy.

Abstract

The increasing use of fossil-based fuels causes an imbalance between energy demand and the availability of that energy. Therefore, the use of rice husk biomass as alternative energy was implemented through the use of rice husk furnaces. This research aims to optimize the efficiency of a small industrial-scale husk furnace by varying the oxygen flow valve holes and the mass of the heated water. The test on the husk furnace was carried out using the Water Boiling Test (WBT) method with the following test parameters: combustion time, FCR, input power, output power, power loss, radiant energy, and thermal conductivity of the pan and chimney of the husk furnace. Tests were carried out on four variations of the oxygen flow valve holes (horizontal: 18 x 36 cm2 and 27 x 36 cm2, vertical: 27 x 24 cm2 and 27 x 12 cm2) and three variations in the mass of heated water (6 kg, 12 kg, and 18 kg). The highest efficiency of the husk furnace was obtained at 18 kg of water, and based on each test parameter, the performance of the husk furnace was most optimal at the horizontal valve hole measuring 27 x 36 cm2 with an average efficiency of 17.32%.
