Abstract

Sentul fruit (Sandoricum koetjape Merr.) is representing one kind of fruit that is amount enough abundance at West Nusa Tenggara, but it hasn’t been exploited in an optimal fashion and more castaway useless. Parts of Sentul plant have been applied as traditional medicine. Sentul fruit can be oxidated by the browning reaction when it is pared or sliced, these symptoms showed the existences of phenolic compounds so that very potential as an antioxidant. To analyze the total phenolic and antioxidant activity of methanol extract of Sentul fruit, the Folin-Ciocalteu and DPPH methods have been used. Results of analysis for three treatment types of samples ( A, B, and C) shown their total phenolic: 6,9 %, 12,86 %, and 9,36 % respectively and also their antioxidant activity shown by values of IC50 of each: 43,36 ppm (1/IC50 = 0,023 ppm-1); 40,53 ppm (1/IC50 = 0,025 ppm-1); and 44,43 ppm (1/IC50 = 0,0225 ppm-1) respectively. These results indicated that Sentul fruit is very potential as an antioxidant.

Abstract

[Title: Students' Understanding of the Nature of Science in Learning using the Mobile-NOS Learning Model]. This research aimed to evaluate the influence of the Mobile-NOS model of learning application towards Students' Understanding of the Nature of Science. In the form of pre-experimental research, this study has been carried out by pretest-posttest non-control group design. The research subjects consisted of 27 students participating in the Basic Chemistry II course in the chemical education program of IKIP Mataram Academic Year 2018/2019 collected by saturated sampling. The Nature of Science data was obtained using the Understanding of Nature of Science questionnaire that consists of 39 valid items with very high reliability (r = 0.802) proved by test result to 84 subjects. A paired sample t-test used to analyze the data obtained. The results showed significant enhancement on students' understanding of the nature of science after the Mobile-NOS model of the learning implementation. The value of t count (5.353) is higher than the t table (1.706) in the one-way hypothesis. Based on the results of the study, it can be concluded that the Mobile-NOS learning model influences students' understanding of the nature of science.

Abstract

The goal of this study is to see how problem-solving learning paradigms affect students' grasp of physics ideas. This study is a quasi-experimental study. The sample was chosen using the cluster random class methodology, which consisted of two classes, the first of which was taught using a problem-solving learning model and the second of which was taught using traditional methods. Experiment classes provide problem-solving opportunities to help students better understand physics ideas, while control classes are taught in a traditional manner. Pre- and post-test results from students in both classes were used to collect data. The two-way Anava-test was applied, and the level of significance was found to be 0.000 (sig. 0.05), indicating that problem solving learning is beneficial in improving students’ understanding of physics concepts.

Abstract

Passive learning leads to low student chemistry learning outcomes. This study aims to improve learning outcomes and students' critical thinking skills on thermochemical subject matter through problem-solving learning model with context-rich problems. This research was conducted in 2 cycles, namely: planning, implementation, observation, evaluation, and reflection. Student learning result data obtained through formative test given at each end of the cycle and students' critical thinking skills adapted to the indicator of critical thinking. Learning outcomes show that classical completeness earns a score of at least 70 85% of the total number of students taking the evaluation test. The results showed that the results of classical evaluation in cycles I and II were 35% and 90%, respectively. Improvement of learning result that is 157%, and critical thinking ability of student in cycle I score that is 45% (uncritical category). In cycle II, the score achieved is 65% (critical category). Increased critical thinking ability reached 44.4%. We conclude that the application of problem-solving learning model with Context-rich problems can improve learning outcomes and critical thinking skills

Abstract

KEK Mandalika is located in a coastal area which is very vulnerable to changes in the quantity and quality of groundwater due to seawater intrusion. This study aims to detect the presence of aquifers (groundwater), seawater intrusion and analyze the effect of physical parameters to determine groundwater quality in the KEK Mandalika area. The physical parameters used are: resistivity, conductivity, Total Dissolved Solid (TDS) and salinity. The resistivity value was obtained using the geoelectric resistivity method with 10 lines using a dipole-dipole configuration, while the other parameters were obtained through 10 samples of well water which were located adjacent to the geoelectric line. Resistivity geoelectrical data processing using Res2Dinv software, Surfer13 software to observe the spread of each parameter and perform regression analysis to see the effect of resistivity, conductivity, TDS on salinity. The results obtained are geoelectric resistivity in the form of an aquifer layer around the KEK Mandalika at a depth of (2 – 12) meters with resistivity values ranging from (0 – 2257) Ωm. The results of groundwater samples are: conductivity with values ranging from (1.02 – 20) mS/cm, TDS with values ranging from (67.3 – 3070) mg/L and salinity with values ranging from (0.05 – 2.07) ppt. The effect of conductivity, TDS on salinity is directly proportional, while the effect of resistivity on salinity is inversely proportional. Most of the KEK Mandalika area is likely to experience seawater intrusion, especially in the Eastern region.

Abstract

The Implementation of Small Group Discussion Learning Methods to Improve Learning Outcomes and Student Activity. This study aims to improve the learning outcomes and activeness of STKIP Paracendekia NW English Language Education students in the Basic Natural Sciences (IAD) course through the application of small group discussion methods. Student cognitive learning outcomes are still low, so it is necessary to apply new methods in learning. The activity in this research includes activeness in asking questions, answering questions, discussing, and presenting. This research is a classroom action research with two cycles. Stages of research include planning, implementation, observation, and reflection. The subjects of this study were 55 students of STKIP Paracendekia NW Sumbawa English Language Education semester I (one) in the Basic Science (IAD) course. Data collection techniques are tests (pretest and post test) and non-tests (observation). The result of this study were an increase in student learning outcomes and activity. Learning outcomes can be seen from the value of the pretest and post test. The average value of pretest and post test in cycle I is 65,22 and 70,67. Cycle II, the average value of the post test is 85,34. Student activeness before the action in only 15 active students. After being given the action, in the first cycle, students were activein asking, answering questions, discussing, and presenting 30 peoples. In cycle II, active students reached 42 peoples.

Abstract

Learning is directly realized from the interaction process between educators and students, supported by learning resources, learning media, and other learning components. As time progressed, various learning problems, especially physics subjects were found, for example, the Covid-19 pandemic, which made it difficult for educators to provide and deliver material to students in class. This study aims to produce valid, practical, and effective android-based interactive learning media on work and energy materials. This learning media uses the ADDIE development method with stages up to Implementation only. After developing the product, the researcher used an assessment questionnaire to determine the product's validity from the media and material aspects. After that, the researcher tested it on physics subject teachers and 36 students at SMAN 14 Surabaya to determine the practicality and effectiveness of learning media. The results of the study obtained the value of media and material validity with an average percentage of 78.5% in the appropriate category, the practicality of the media obtained an average percentage of 93.5% in the very practical category, and the effectiveness of the media can be seen from the increase in learning outcomes students who get the effectiveness of 0.70 in the high category. Thus it can be concluded that the media is feasible and practical to use in the learning process and is very effective in motivating students to learn physics.
