Abstract

Bunut is one of regions in Kisaran. The majority of Asahan District work as shoe craftsmen. The length time of shoes making procces make the shoe craftsmen need long time to market it. Similarly when designing shoe model that still us traditional tools that make shoe’s model impressed outdated. In terms of making Bunut shoe is not easy. Cutting leather shoe that use traditional tools make the cutting process of the shoe becomes long. The method is started from designing a modeling tool, preparing tools and material, making and testing machines. The result obtained by this shoe modeling machine work optimally 8 hours per day with the cutting velocity 1,4 minutes for each shoe's pattern, from the result modelling machine able to cut design pattern a pair of shoes in 40 minutes. So in one day it can produce shoe pattern pieces is able to produce 12 pairs of shoe patterns from the previous one, only 2 pairs per day.

Abstract

The implementation of learning, especially Physics, is currently based on the results of observations still experiencing several obstacles. The tendency of passive students and learning outcomes as part of students still shows results that have not been maximal. Based on this fact, this classroom action research was carried out to improve the learning process and physics learning outcomes of students in the fluid material in class XI IPA1 SMA 4 Pekanbaru, using PHET (Physics Education Technology) media. The type of research conducted is classroom action research consisting of 2 cycles, with the subject are students of class XI SMA Negeri 4 Pekanbaru. Time for the implementation of odd semester 2018/2019 academic year. Data collection techniques used observation sheet instruments for learning activities and fluid material test sheets for physics learning outcomes. Data is analyzed descriptively in percentage representation. The results of the research showed that the learning activities of students had increased from cycle I to cycle II. Furthermore, for physics learning outcomes, students increase from the first cycle to cycle II, with the average results obtained by the good category. Therefore, the application of PHET-based information technology simulation media in physics learning can improve learning activeness and learning outcomes of class XI students of SMA 4 Pekanbaru.

Abstract

In general, this research aims to produce a valid magnetic induction experimental device as a medium for learning physics in high school. The experimental device consists of experimental equipment and tool usage manual. In particular, this research aims to design, build, and validate devices for magnetic induction experiments on coiled wire as a physics learning media according to the research development steps. Three experts and two physics teachers as users have been involved to provide an assessment of the experimental devices that have been built. Assessment is carried out on the construction and content of the experimental device. The results of data analysis showed that every aspect of the assessment of the experimental tool was declared valid with a very good category (index validity 3.34) and the manual for using experimental tools was also declared valid with a very good category (index of validity 3.47). Thus, it can be said that the magnetic induction experimental device in circular wire is declared valid as a medium for physics learning.

Abstract

Andaliman has the Latin name Zanthoxylum acanthopodium and is a family of Rutaceae. Andaliman is a native spice from North Sumatra called the golden spicy from North Sumatra. Andaliman farmers in Parsoburan Village, Toba Samosir said that one of the problems in andaliman production is the number of Andaliman fruits that are still not effective, even most of the Andaliman fruit becomes rotten. The design of Andaliman perfume machine has been carried out which aims to increase the usefulness of Andaliman through the manufacture of andaliman perfume as well as to increase the economic value of Andaliman. The method used is by designing a perfume machine and making an official perfume machine, testing the machine and using a perfume machine. Making perfume machines and testing perfume machines was carried out at the UNIMED Mechanical Engineering Workshop and the implementation of machine use activities was carried out in Parsoburan, Toba Samosir Regency. The results obtained from the andaliman smoothing machine were processed as 2 kg of perfume in a single smoothing process, for the heating stage mixed with 300 mL ethanol and the results of the perfume ± 20 mL which will be mixed with alcohol according to the strong aroma made.
