Abstract

Tujuan penelitian ini untuk mengolah sampah plastik menjadi BBM dengan metode pirolisis sebagai energi alternatif dan mengolah kembali gas hasil pirolisis sebagai sumber energi. Metode penelitian yang digunakan adalah eksperimen. Data  hasil  penelitian dianalisis  dengan  cara  mengamati secara  langsung  hasil  eksperimen,  kemudian menyimpulkan   dan   menentukan   hasil   penelitian yang  telah dilakukan dengan menggunakan teknik analisis regresi berganda. Parameter yang diamati dalam penelitian ini adalah suhu reaktor, waktu pirolisis, dan densitas minyak plastik. Pirolisis sampah plastik ini menggunakan sampah jenis PolyPropylene dan sampah plastik jenis High Density PolyEthylene. Proses  pirolisis  dijalankan  dalam  reaktor yang berisi 0,5 kg plastik dengan variasi suhu 1000 C, 1500 C, 2000 C, 2500 C, dan 3000 C. Untuk menghemat bahan bakar dalam menamaskan reaktor maka digunakan gas sisa pirolisis yang tidak dapat terkondensasi pada tabung kondensor. Hasil penelitian menunjukkan minyak hasil pirolisis terbanyak dari sampah plastik PolyPropylene dan High Density PolyEthylene diperoleh pada suhu operasi 3000 C sebanyak 110 ml dan 145 ml. Waktu tercepat proses pirolisis plastik PolyPropylene adalah 60 menit  dengan nilai densitas minyak sebesar 818,181 kg/m3dan plastik High Density PolyEthylene adalah  30 menit dengan nilai densitas minyak sebesar 714,285 kg/m3 serta 551,728 kg/m3. Densitas  minyak  hasil  pirolisis  pada plastik PolyPropylene mendekati densitas bahan bakar etanol dan solar masing-masing 777,777 kg/m3 dan 818,181 kg/m3. Sedangkan pada plastik High Density PolyEthylene nilai densitas mendekati bahan bakar bensin sebesar 714,285 kg/m3. Data analisis regresi berganda pada plastik PolyPropylene dan High Density PolyEthylene menunjukkan bahwa suhu, waktu pirolisis dan densitas memiliki hubungan yang sangat kuat dan saling mempengaruhi satu sama lain. DOI : 10.29408/kpj.v4i1.2156

Abstract

Many theories of learning are appear from education experts. Not just environmental education in formal schools that make students understand the science. Instill a sense of love, happy, interested, and need to students is one of the effective tips for the success of learners. Teachers should be able to change the atmosphere of a stiff  or lesson class becomes more enjoyable. By offering a lighter atmosphere and pleasant feel would give a positive effect on learners. The aim of this study is to change the view that physics was stiff and boring into physics fun through games in learning physics. The benefits of this research is to give response to prospective physics teachers to be able to give a pleasant impression on the subjects of physics. Result of this research is the implementation of the learning game physics can drop the impression of stiffness of physics teacher. It is shown by the percentage of students who apply games in physics have motivation  79.5% better than the control group that had motivated 68.375%. In addition, 76.5% of students responded positively to teach prospective physics teachers in implementing the learning game physics, while the group that did not apply in the learning game physics only 68.625%.

Abstract

The purpose of this study was to describe the application of the think-pair-share method with article analysis to improve students' higher order thinking skills. This type of research is pre-experimental with research subjects, namely students who take the Physics Learning Strategy course, academic year 2020/2021, at one of the universities in Mataram, totaling 27 people. The research design used was One Group Pre-test and Post-test Design. The instrument used in this study was a test of higher order thinking skills. The level of higher order thinking skills of students is calculated as a percentage, with 5 categories. The increase in score is calculated using N-gain, with 3 criteria. The results showed that the level of high-order thinking skills of students at the pre-test was 49 with a very low category, while at the time of the post-test it was 83 in the good category. The N-gain score is 68 with moderate criteria. Thus, the application of the think-pair-share method with article analysis can improve students' higher-order thinking skills in the Physics Learning Strategy course.

Abstract

The use of student's worksheets in biology physics lectures will contribute to optimizing the achievement of learning objectives in conveying material from lecturers to students and the achievement of scientific literacy skills to students. This article aims to describe the validation of student worksheets in Biology Physics courses to improve student scientific literacy. Development research was carried out in the Lambung Mangkurat University Physics Education Study Program 2019/2020. Validation is one of the processes at the part of the development stage. The validity of student's worksheets is measured using a validation sheet and then determined based on validation by experts which are stated as Valid or invalid. If valid, it will be categorized again as very good, good, enough, less, and not very good. The conclusion of this article is the Student Worksheet for increasing scientific literacy in Physics Biology courses is valid in both categories. Thus this Worksheet can be implemented for further testing at the dissemination stage.DOI: 10.29408/kpj.v4i1.1722

Abstract

The process of learning physics at various levels of education is still faced with several difficulties, especially the use of interactive multimedia which is still lacking so that educators are required to innovate to develop interactive multimedia to increase interest in learning and student learning outcomes. This research is a development research that aims to produce interactive multimedia based on problem based learning that is valid, effective, and practical to improve student learning outcomes on parabolic motion material. The research development model used in this study is a 4D (four D) model consisting of define, design, develop and disseminate. The instruments in this development research consist of interactive multimedia, syllabus, lesson plans, LKPD, test instruments. The data collection techniques used in this study were expert validation, limited trials and student responses. The results showed that interactive multimedia had an average score of 3.12 with a very good category, the syllabus had a score of 78.08% with a very valid category, lesson plans had a score of 73.66% with a fairly valid category, LKPD had a score of 75.50% with a very valid category and the test instrument has a score of 77.60% with a very valid category. Interactive multimedia based on problem based learning is effectively used with an average score of 3.04 with a very good category and is effectively used because there is an increase in learning outcomes with an N-gain value of 0.49 having a medium category. Interactive multimedia based on problem based learning on parabolic motion material is valid, practical, and effectively used in learning so that it is suitable for use in the learning process and proven to improve students' cognitive learning outcomes

Abstract

In this study, research was conducted on the analysis of Cu concentrations in mangrove plants (Rhizophora.sp) using the Atomic Absorbtion Spectrophotometry (AAS) method in the Gilimanuk Jembrana port area of Bali. The research was conducted on June 23, 2019 until July 28, 2019 in the Faculty of Mathematics and Natural Sciences, Udayana University. The method used is Atomic Absorption Spectrophotometry (AAS), a principle that is based on the process of absorption of energy by atoms that are at the level of basic energy (groundstate). The sample used is in the form of root stems and leaves of mangroves that are cleaned and destroyed in advance, because AAS can only analyze the material in the form of liquid. The results of the analysis with AAS are the Cd metal content at Gilimanuk port has exceeded the threshold of the quality standard that is in accordance with sea water quality standards according to Environmental Decree Number: KEP-MEN LH No.51 / Men KLH / 2004 Cd threshold for tourism marine is 0,002 ppm and for biota is 0,001 ppm, while mangrove is included in marine tourism with a threshold of 0,002 ppm.
