Abstract

The manufacture of pineapple leaf fiber decorticator machines has been made in the village of Onan Runggu III, Sipahutar District, North Tapanuli Regency. Machine making aims to help pineapple farmers to overcome the problem of waste and pineapple. The method used starts from feasibility studies, designing machines, collecting and purchasing tools and materials, evaluating results and testing tools. Results obtained by the pineapple leaf fiber decorticator machine 0,12 kg/hour obtained through two stages of grinding namely grinder 1 and grinder 2. The final results obtained from the decorticator machine of pineapple leaf fiber are pineapple leaf fibers that can be used to make raw materials for textile products.

Abstract

West Sumatera is a disaster prone area, especially disasters such as earthquakes, landslides, floods, tsunamis, and volcanoes. The high potential of natural disasters has consequences for the importance of disaster mitigation efforts. School is an effective tool in shaping of mindset and behavior of students. One effort that can be done is integrate the topic of natural disaster into learning, especially physics learning. Integrating physical matter in learning requires material analysis aimed at making disaster topics integrated in accordance with learning topic. The type of this research is descriptive research. The results of the research indicate that an analysis of the relevance of learning material to the topic of integrated disasters needs to be done so that the integration between teaching material and the topic of disasters is carried out in harmony. Almost all physics learning material can be integrated with the topic of disasters that often hit the West Sumatra region. The classification of material on the topic of integrated disasters is classified into fact and metacognitive material.

Abstract

Indonesian nation is renown as a nation that has cultural heritage of high value, one of them is the relics of archaeological sites of Barus Kingdom in Lobu Tua Tapanuli Tengah regency. Have  to be investigated using study early detection of the presence of archaeological sites by based combintion  geoelectric method with geomagnetic which aims to determine the presence of the sites in Lobu Tua based combination  geoelectric method with geomagnetic. Date processing is done by geoelectric research area is dominated by alluvium rock with the resistivity 55,3 – 705 at depth 6 m - 30 m and tuff with the resistivity 2600 – 4601 at depth 1,25 m - 6 m and andesite rocks with the resistivity 500 – 2300. Qualitatively, the result shows there are magnetic anomalies part with high value is -90 nT, susceptibility value ranged between 0,714 – 0,994 interpreted with sand  and susceptibility value ranged between 1,008 - 1,261 interpreted with alluvium rocks. So the research area of archaeological sites in the city of Barus dominated by alluvium rock. Where from Of both methods Can be interpreted rock archaeological sites in the city of Barus with alluvium rocks.

Abstract

The learning process of physics at school, the topics is sometime less relatedto the existing dailylife phenomenon.This condition causes low improvement of students' cognitive learning result. In this case, it was a necessary to apply a learning model to improve student learning result by applying phenomenon based learning model (PhenoBL). Quasi experiment in the form of nonequivalent control group design as the model of the research. The instrument to collect data used test of student cognitive at pretest and posttest, respectively. The Data was analyzed by descriptive and inferential analysis. The results of descriptive analysis show the average absorption rate of experiment class is 71.05% and control class is 63.33% which both classes are in a good category. In the paired sample t-test results stated an increasing of students cognitive learning outcomes from pretest to posttest. This can also be seen from the inferential analysis in that means there was a significant differences between experimental class and kontrol class. Thus, it can be concluded that the use of PhenoBL model can improve student learning outcomes of class XI MIPA SMA Negeri 5 Pekanbaru on optical material.

Abstract

The purpose of this research is to know the student learning outcomes and student learning activities that use Cooperative Type Group Investigation model and conventional learning. The type of research is quasi experiment, and the sampling is done by simple random sampling. The instrument used is the cognitive learning outcomes test. From the data analysis for the experimental class learning outcomes, it results in an average of  pretest 46,667 and posttest 73,714. The control class results in an  average of  pretest 40,381 and posttest 60,761. The result of data analysis using t-one test, when the result of t test is thitung = 4,056 while ttabel = 1,668, thitung> ttabel. Because then there is a significant difference, this shows there is the influence of the use of cooperative learning model of type group investigation of toward student learning outcomes content Work and Energy in class X Semester II SMA Negeri 12 Medan T.P 2016/2017.
