Abstract

This study aims to describe the effectiveness of the inquiry learning model to improve students' cognitive learning outcomes at the temperature and heat of class XI from one public school (SMAN 1 Gerung). This type of research is a quasi experiment with the basic pattern "The One Group Pretest-Posttest Design" and descriptive method. The research instrument used was the observation sheet applying the learning model and test the learning outcomes in the cognitive domain (C1 to C6). Assessment of learning implementation using a scale of 1 to 4. Student learning outcomes are said to be complete if 80% of students obtain a minimum value of 75. The results of this study indicate that: the implementation of learning increased from the criteria both in the first meeting to rise to be very good criteria at the fourth meeting. Student cognitive learning outcomes increased from 43 in the pre-test to 78 in the post-test, with classical completeness of 84%. The conclusion of this study is inquiry learning effectively improves students' cognitive learning outcomes in temperature and heat.

Abstract

The SASAMBO (Sasak, Samawa, Mbojo) tribe has a variety of medicinal plants. The abundance of SASAMBO tribal medicinal plants can be used in learning the natural product chemistry which are expected to support traditional health tourism on the islands of Lombok and Sumbawa. Natural product chemistry examines the chemical content associated with the efficacy of a medicinal plant. This linkage can provide scientific support for the use of SASAMBO traditional medicinal plants. The method used in this research is the study of literature and questionnaires. Data sources came from public records, the results of questionnaire responses, and scientific articles related to SASAMBO traditional medicine. The results showed that there were various SASAMBO medicinal plants which were potentially used in the study of natural product chemistry with details, Lombok (Sasak) 43 species, Sumbawa (Samawa) 25 species, and Bima (Mbojo) 35 species. Some of these plant species are used for the treatment of diseases caused by viruses, so it has the potential to be used to treat corona outbreaks. Lombok and Sumbawa islands have abundant medicinal plants, this makes the two islands potential as a traditional health tourism destination.

Abstract

This study aims to develop a cooperative learning model of KOSAJI type that valid, practical and effective. KOSAJI of cooperative learning model is a collaboration between cooperative learning model type STAD and Jigsaw in physics learning. The method used was the research development model adopted Dick and Carey with ten stages which includes a needs analysis to determine the objectives, formulate indicators, the analysis of the students and the context, the establishment of specific goals of learning, the development of assessment tools of learning, the development of learning strategies, the development and selection of material lesson, formative evaluation, revision of the device, and a summative evaluation of the effectiveness of the device. This research was conducted at SMAN 1 Mataram. KOSAJI cooperative learning model developed together with learning devices such as lesson plans, worksheets, questionnaires students' attitude towards physical and cognitive achievement test. KOSAJI learning model along with the device has been through expert validation, test a small group, limited field testing and large-scale (summative evaluation). Implementation KOSAJI learning model in teaching physics to minimize shortage and optimize the advantages that exist in both the type of cooperative learning model. Based on expert validator test KOSAJI learning model and is well worth learning device used with a percentage value of 94.99% . After going through the stages of the test group was small and limited field KOSAJI learning model can be applied to both in terms of the response of the students (80.52 % on a small test group and 83.41% in the limited field testing ), the response of teachers (76.92 % in the small test group and 82.69 % limited field tests) and enforceability of RPP (86.61 % on a small group of test and 86,62 % in limited field test) with some revisions .Summative test results showed that the learning model KOSAJI effectively improve students' cognitive learning outcomes with increased value in terms of pretest and posttest of 41.93%. Therefore, the development of cooperative learning in teaching physics KOSAJI proved valid, practical and effective.Keyword: KOSAJI Cooperative Learning Model, Physics Learning

Abstract

Discovery learning (DL) model is a learning model that hones students' process skills in finding concepts. Science process skills are needed to support optimal learning outcomes. The absence of a laboratory is thought to be the cause of the less optimal learning process so that supporting media such as virtual laboratories (VL) are needed. This study aims to determine the effect of implementing the VL-assisted DL model to improve Science Process Skills (SPS) and student learning outcomes in the circulatory system material. The research design used was the pretest-posttest control group design. The study population was all students of class VIII Junior High School Darul Ihsan Aceh Besar, and the sample selection was using random sampling techniques so that 60 students were selected as the research sample who were divided into two classes. The results showed that the application of the VL-assisted DL model in the experimental class experienced an increase in SPS by 71.05 (high category) compared to the control class. The application of the VL-assisted DL model also experienced an increase in learning outcomes, namely 73.16 (high category). The conclusion in this study is the application of the VL-assisted DL model to the circulatory system material has an effect on improving SPS and learning outcomes

Abstract

The research aim to identify the mechanical properties of  Areca nut fiber composite.. Pinangs fiber composite board uses polyester resin as a binder. Areca nut fiber that used in this research is fiber obtained from pinang which is old and not used anymore. The sample was made by varying the concentration of fiber used (30%, 40%, 50% 60% and 70%). From the results of tests conducted, there are differences in mechanical properties of pine fiber composite material on tensile test and press tests performed. In tensile test, composite of pinang fiber with 50% fiber concentration is the fiber with the best mechanical properties because it has the highest tensile strength, maximum length and maximum load, that is 16.35 MPa, 2.06 mm and 3147.45 N. Meanwhile, Composite betel fiber with a concentration of 30% has the highest broken modulus (MOR) at 30.43 kg / cm2, and elastic module of 1980.2 MPa

Abstract

This research was carried out to investigate the effect of temperature in carbon production on its performance in the catalystic cracking of CPO to fuel.  The carbon was produced using palm shell at 2 different temperatures (450 and 550oC).  The cracking of CPO was carried out with and without the active carbon catalyst.  The result showed that the use of catalyst increase the conversion of both gas and liquid conversion.  The use of higher temperature in the production of active carbon catalyst increased the performance of the catalyst, in particular, for the liquid conversion. Keywords :Activated carbon, catalyst, catalytic cracking, crude palm oil

Abstract

To improve the quality of the Nuclear Physics lectures in addition to understanding the material as knowledge aspect, students are also expected to practice for the skills. The Nuclear Physics lecture material is microscopic so it requires laboratory activities, but there is no suitable practical tools available in the laboratory of Physics Department, mathatics and science faculty, universitas negeri padang. Therefore, a virtual laboratory model was developed in this research which was supported by students' worksheet. The valid and practical students' worksheet have been obtained. Then, it was tried out to students who take the Nuclear physics lecture to see whether the students' worksheet are effective to support virtual laboratory activities. The research conducted is included in the type of quasi-experimental research. The population is students who take part in the Nuclear Physics lecture in semester January-June 2018. The samples were taken using Cluster Random Sampling techniques. Data on knowledge and skills competencies were analyzed using the t test at a real level of 0.05. Based on the results of data analysis, there were significant differences in the two sample classes. The results of the regression analysis indicate that there is a strong correlation between the use of students' worksheet to support virtual laboratory activities for knowledge and skills competencies.Keywords: Nuclear Physics, Students Worksheet, Virtual Laboratory
