Abstract

Palm oil-based cooking oil is the most widely used cooking oil. Palm oil circulating in the market is often mixed with animal oil by culinary entrepreneurs with a view to produce a more tasty taste so it needs to be examined purity. Research on the content of saturated fatty acids using gas chromatography mass spectrophotometer (GCMS) requires quite expensive cost so that an alternative method is needed to determine the quality of cooking oil; especially its purity is by using polarization both naturally and by electrooptic method. This research uses incandescent lamp as light source. Samples flanked by parallel metal plates are placed between polarizers and analyzers. Samples of a mixture of palm oil with each animal oil (chicken oil, pork oil, cow oil). The samples of each oil are tested byu using natural polarization (active polarization) and electro-polarization polarization (impact polarization). The results showed that the polarization angle change in the oil of the mixture was greater than that of pure palm oil with the greatest angular change produced by a mixture of palm oil and cow oil (1.5 for natural polarization and 3 for electro-polarization). This result was in accordance with the result of the titration test shows that mixed oils have free fatty acids and PV peroxide numbers higher than pure palm oil. The cow's oil mix is the greatest change compared to pigs and chickens. This result shows that cow's oil has the highest saturated fatty acid content. Electrooptical polarization angle larger than natural polarization. This is due to the interaction of the electric field of the light source with the electric field of the molecule induced by the electric field of the power supply. The polarization method successfully distinguishes the type of pure and mixed cooking oil.

Abstract

The use of animal oil for various purposes by the people has inspired this study. The purpose of the study was to distinguish the mixture of cooking oil palm and variety of animal oil (chicken oil, beef oil, and pork oil). The composition of the mixture of palm oil and animal oil is 3:1 mL, respectively. The light source used were He-Ne laser of 1 mW (λ = 633 nm) and IR lamp of 250 watt (λ = 750-800 nm). Measurements were made based on changes in the natural polarization angle (0 kV) and electrooptics (6 kV). The result showed that the natural polarization angle changes and electrooptics of  mixture of palm oil and animal oil greater than pure palm oil, both at He-Ne laser and IR light. This is consistent with the results of the titration test, peroxide value and free fatty acids (FFA) oil mixture was greater than pure palm oil. Change in the polarization angle represents the presence of saturated fatty acids. Animal oils have saturated fatty acid content greater than palm oil, so the polarization angle changes of oil mixture is greater than polarization angle changes of pure palm oil. Keywords: animal frying oil, palm oil, polarization angle

Abstract

Teachers' Teaching materials are still limited, such as simple worksheets or textbooks. The available teaching materials are not yet integrated with the verses of the Qur'an and are not technology-based. One of the technologies currently being developed is Augmented Reality (AR) which can convert 2D images into 3D ones. AR is an innovation used to reduce the weaknesses of books and e-learning and can assist in visualizing things. Therefore, developing an integrated physics learning module using Augmented Reality with Al-Qur'an verses on fluid material is necessary. The type of development research used was the 4-D model, namely definition, design, development, and dissemination. However, this study is only in the development stage with limited trials. This study aims to produce an integrated physics learning module using AR based on Al-Qur'an on fluid material for senior high school that is valid and practical. Validation was obtained from some aspects, which are contents, media, and Al-Qur'an interpretation. The results showed that this module is very valid based on these three aspects (92% for contents, 83% for media, and 92% for Al-Qur'an interpretation). Practicality was obtained by a limited trial with students and physics teachers of MAN 2 Payakumbuh. The results obtained in this study are 89% for students and 91% for teachers. It means that this module is very practical. So, this module is very valid and practical for use in learning by teachers and students. From the results of this study, it can be concluded that the integrated physics learning module uses Augmented Reality with verses of the Qur'an in fluid material that meets the requirements with very good quality and is very suitable for use as a supporting teaching material in learning. The implications of this research will positively impact the development of Physics learning media in the future; using media learning based on augmented reality (AR) can provide information for educators on how to use appropriate learning media in the learning process.

Abstract

This study aimed to determine whether students who used the Self Organized Learning Environments (SOLE) learning model using the Microsoft Teams application had better learning outcomes than students who used the face-to-face learning model. The post-trial-only control group design is a study design used in quasi-experimental studies. The population of this study was XI IPA SMA Negeri 1 Bukittinggi. Two classes are sampled, that is, experimental class XI IPA 7 and control class XI IPA 6, which are sampled through normality test, homogeneity test and population mean similarity test. The sampling method uses simple random sampling where the results of the analysis found that both classes of samples are normally distributed, have homogeneous variants and the average population class is the same. The 20-question final exam is a tested and analyzed research tool. The experimental class achieved an average overall score of 80.13 for the cognitive domain, while the control class got an average final test score of 77.28. For the affective domain, the average value of the experimental class was 73.19, while the average value of the control class was 71.61. For the psychomotor domain, the average value of the experimental class was 73.51, while the average value of the control class was 70.04. The research hypothesis explains that "the learning outcomes of students who apply the SOLE (Self Organized Learning Environments) learning model assisted by the Microsoft Teams application are better than the learning outcomes of students who apply the direct learning model" formulated based on research results.
