Abstract

High levels of phosphate in waters, the majority of which comes from domestic liquid waste containing detergents. To overcome pollution arising from domestic liquid wastewater, wastewater treatment is absolutely necessary. The urgency of this research is very important in that an environmental mitigation engineering system is sought, so that it can reduce or even eliminate these pollutants if possible. The waste processing technique using plants is known as phytoremediation. Phytoremediation using water hyacinth plants. The analytical method in this study used a completely randomized design (RAL) where each treatment was repeated three times with an additive linear model for a two-factor factorial design with an environmental design in the form of RAL which was analyzed using the SPSS program. If the results of the analysis of variance show an F-count value > Ftable 0.5, a further test is carried out using the Tukey further test (honest significant difference). The results of this research were that the pH value was 6.9, close to the normal pH of water, and the temperature was around 26-25 0C. The BOD level decreased further over 7 days. Phosphate levels also experienced changes in concentration levels which decreased on day 7. The TSS value increased greatly. The TSS value greatly increased the yield and the color changed to cloudy brown.

Abstract

By conducting an analysis of the influence of solar radiation temperature on the output power of a 150 Wp Pematangsiantar solar cell whose energy source comes from renewable energy, which is the sun, it is hoped to help the community's maximum needs by obtaining it directly from solar energy, in addition to being cheap, the use of solar energy has never exhausted, the maintenance cost of Solarcell is also very reasonable and not least it does not produce pollution that can damage the environment. This research aims to find out the performance of a 150 Wp solar panel in producing electricity in the form of current, voltage and power to charge a battery with a capacity of 12 V 7 Ah. Research data collection was carried out at 08.00 WIB - 17.00 WIB. The test to determine the current, voltage and power in this study uses several components, namely a 150 Wp solar panel, solar charger controller, battery, voltmeter and ammeter Testing of a 150 Wp solar panel as an alternative energy source and data taken every hour for 9 hours. The magnitude of the current and voltage from the solar panel can be read directly. Each solar panel has a different level of efficiency. In general, solar panels on private residential solar systems have a standard temperature of 25°C (77°F), with a general temperature range between 15°C and 35°C. It is in this temperature range that solar panels perform best. The limit point for solar panel efficiency is 65°C (149°F). Above this temperature, the performance efficiency of the solar system can be disrupted due to the drop in voltage produced.

Abstract

Ethnophysics is part of ethnoscience which studies and presents the relationship between physical knowledge and culture. The knowledge of physics regarding the matter of force and heat is a complex material and is widely applied in everyday life. However, some students do not like physics subjects, especially in the material of force and heat because there are many physics equations that make students bored to memorize. Therefore it is necessary to have a strategy for presenting physics material so that it is comfortable and liked by students. One of them is by being connected to the local culture. This study aimed to explore the making of Langkat pottery as a local wisdom in North Sumatra which can be used as a medium for learning physics. The research method used was descriptive qualitative with data collection techniques through observation, questionnaires and interviews. The data obtained were then analyzed, verified, and reduced then constructed into scientific knowledge and interpreted into physics concepts in class X high school physics learning. The results showed that the process of making Langkat pottery could be used as a medium for learning physics on force and heat.

Abstract

Two assessment systems in education are summative assessment and formative assessment. One example of a formative assessment is the progress test which is carried out once a year at the Faculty of Medicine and Health Sciences (FKIK) at Warmadewa University. The progress test aims to determine the extent to which competencies have been mastered by students, stimulate long-term retention and stimulate deep learning behavior. This study aims to determine the relationship between progress test scores and grade points of 2017 FKIK Warmadewa University students. This research is an analytical study with a cross-sectional design. The population in this study were 95 students of the 2017 FKIK Unwar class, 76 people fulfill the inclusion criteria and 2 people were excluded based on exclusion criteria so that the final population was 74 people. The study uses secondary data including progress test scores, odd semester social studies and GPA. Secondary data will be processed using the SPSS application. The results of the bivariate analysis showed that there was a significant relationship (p<0.05) between the score of the progress test and the achievement index with a weak strength level (r=0.20-0.39), moderate (r=0.40-0.59) to very strong (r=0.80-1). The average grade 2017 progress test score is 31.2. The average grade point average for odd semester 2017 students is 3.49. The cumulative grade point average for the 2017 class is 3.47. Suggestions that can be given are for students to take the exam seriously so that the progress test scores can describe their cognitive abilities.

Abstract

This research aims to validate the IKARME learning model in training students' scientific communication skills. This research uses development research through a validation study design by testing two criteria, namely content validity and construct validity. Validation involved three experts through Focus Group Discussion (FGD) activities. The research results show that the IKARME model is valid and reliable. This is based on calculations using the Aiken formula, that the V value for each instrument item is 0.75 ≤ V ≤ 1 with a very valid category and the reliability coefficient for each aspect of validity is in the range of 100% so that the validity results developed are reliable. It was concluded that the IKARME model was declared valid both in terms of content validity and construct validity to be able to improve students' scientific communication skills.

Abstract

[Analysis Of Factors Causing Mathematics Anxiety In Instiki Bali Students]. The aim of this research is to determine and explain the factors that cause anxiety about learning mathematics at INSTIKI. This research is descriptive with a qualitative approach. The subjects of this research were INSTIKI Bali students. Research data was collected using questionnaires and interviews. The research results show that the anxiety learning mathematics experienced by INSTIKI Bali students is categorized into three groups, there are students with high, medium and low learning outcomes. Factors that cause anxiety about studying mathematics in the high learning outcomes category are intellectual factors including confusion with the material, personality and environmental factors in the form of being stressed during learning due to lack of understanding of explanations but being embarrassed to ask questions, and other factors, namely fear if the grades do not match expectations. The moderate learning outcome category is caused by intellectual factors in the form of lack of ability to learn mathematics, personality factors include lack of self-confidence, and environmental factors include fear of not being able to answer questions that are suddenly given and fear of not being able to solve problems in front of the class. The anxiety factors causing the category of low learning outcomes are intellectual factors in the form of a lack of understanding of mathematics and anxiety during exams, personality factors including of lack of self-confidence, and environmental factors including fear of learning in class and feeling monitored and intimidated by class conditions during learning.
