Abstract

Laundry wastewater has the potential to pollute the aquatic environment if it is thrown away in large volumes without any prior treatment. The easy and inexpensive laundry wastewater treatment method for household-scale has been carried out through the filtration method using a combination of natural adsorbent as a laundry wastewater filtration media. This study aims to determine the effect of filtration using a combination adsorbents of activated charcoal, zeolites, silica sand, anthracite and ferolite on pH, TDS (Total Dissolved Solid), electrical conductivity and temperature values ​​in laundry wastewater samples. Based on laboratory test results, it was found that after the filtration process, a pH value of 22.2% was decreased, the TDS level was 21.5% and the conductance value was 15.1%, while the temperature value was relatively stable. Statistically, the presence of filtration treatment only gives a significant influence on changes in pH, TDS and conductance values ​​while the relative temperature value does not change.

Abstract

Working voltage diode can be determined based on the exponential form equation that states the relationship between the variable electrical current , voltage , and temperature diode electron charge . Determination of potential voltage diode can be done numerically using the method of looking for the root of the equation . There are several methods of searching for the roots of the equation graph method , the direct method , the two methods , regulation falsi method , Newton – Raphson method and the secant method.The purpose of this study is to show which method is most effective in determining the working voltage diode . The method used is descriptive analytic method . The results showed that the direct measurement method is a short procedure , obtain employment diode voltage v = 0.42216 volts at the 4th iteration , as well as the method of Newton - Raphson procedure is also very short because it only took 5 steps in determining the working voltage diode . The other method , the method for two , regulations falsi and secant method requires a longer iteration. Themethod is effective in determining the working voltage of diode 5selected method I sadirectmethod an dNewton-Raphson method

Abstract

Research on the application of incuiri strategis for improve mastery of the conceps of vibration and waves.The purpose of the study is 1) Knowing the relationship of mastery of the initial concept with the result of learning to study physics students junior high school Savio Dominiko Manado on matter of vibration and waves.2) To Determine the effectiviness of applying inquiri learning strategies in vibration and wave material. The physic material used is vibration and waves. This study used the experimental method Pre-test and Post-test control group design. The research subyek taken in this study were the 8 th grade students of Catholic high school Savio Dominiko Manado with a total of 22 students. Data collection was carried out by holding a Pre-test and Post-test to find out the mastery of the conceps of vibration and waves. Data is processed using t test statistic. The results of the study show 1) there is a positive and significant relationship between mastery of the initial concept and achievement of student learning outcomes on vibration and wave material seen t count = 2,196 while t table =20,18. 2) Student group learning outcomes taught with conventional learning strategies that can be seen from average value of achievement for the control class is 70,0 and also seen from t count t count t table that is obtained t count = 1,975 while t table = 1,721

Abstract

There are quite a lot of high school physics books available, but contextual teaching materials based on local wisdom are still lacking in schools. Explicitly the 2013 curriculum provides an opportunity for schools and teachers to develop contextual and local wisdom teaching materials but their determination and motivation are still encouraged and encouraged. In increasing the competence and professionalism of alumni as prospective physics teachers, it is necessary to be equipped with experience in designing contextual regional-based teaching materials. Research on the development of teaching materials based on local culture Kolintang music instrument carried out for 6 months. To build competence as a whole and systematically, the focus of research (development of teaching materials) is: (1) determining the main elements in teaching materials namely attitudes (curiosity about natural phenomena), processes (problem solving processes), products (in the form of facts, principles, theory, and law), and contextual (application in everyday life). 2. Studying the previous teaching material to be developed seen from the aspect of breadth, depth, whether or not there is a concept map, a decrease in formulas (mathematical aspects), student worksheets (LKS) to make observations. 3 Testing of teaching materials in schools as a test of the feasibility of using teaching materials. The efficiency and productivity of students increases as reflected in the improvement of their learning achievements. The results showed that the formulation of physical concepts contained in the Kolintang music instrument play are the concepts of momentum and impulse, the concept of vibration, the concept of resonance, the concept of sound waves (longitudinal waves), the concept of sound propagation in the air / gas medium, the concept of period and frequency sound produced by each type of instrument, the concept of sound wave energy and the concept of the intensity of the sound waves produced by kolintang. Physics teaching materials integrated with Minahasa culture Kolintang tools for high schools are suitable for use in schools.

Abstract

Blended learning is a learning strategy that utilizes internet technology combined with face to face in class. The purpose of this study was to improve student learning outcomes in the material of Class XII Dynamic Electricity in SMA N 2 Tondano. This research is an experimental study with the design of the One Group Pretest-posttest design. The sample taken was Class XII IPA as an Experiment class with 22 students. Data is collected by conducting research observations and giving tests. The data were analyzed from the posttest results and from the process assessment students were in the good category 66% -79% and very good 80% -100%. In the normality test, researchers used the Liliefors test in Lcount = 0.162 while Ltable = 0.184 because Lcount <Ltable, then the data was normally distributed. Furthermore, hypothesis testing was done by t test at 5% significant level, obtained tcount = 5.215 while t table = 1.721 because tcount> ttable, so that it can be concluded that the Blended Learning learning model has an effect on student learning achievement.
