Abstract

Abstract Mistakes in solving math problems are common for students. Most teachers often do not pay attention to the types of mistakes made by students. The types of mistakes made by students can be one of the successful benchmarks of mathematics. This study aims to describe the types of problems of students in solving mathematics problems at Al-Kindi Middle School Pekanbaru. The research method used is descriptive research with a form of qualitative research. Data collection techniques used are tests and interview, data analysis techniques used descriptive qualitative and quantitative. Subjects in the study were 26 students and objects that answered tangent questions circle 5 questions. Based on the results of data analysis it can be concluded: students make fact errors 17%, concept errors 34%, principle errors 39% and operating errors 10%. The biggest type of error is a mistake in principle and concept. The implication is that teachers need to understand the concepts and principles when teaching, so the level of errors in solving problems is low. and to the next researchers, to be able to carry out further in-depth research to improve the quality of mathematics education in schools related to students' mistakes in solving tangent circle material questions. Keywords : error analysis, tangent circle.

Abstract

The identification of heavy metals Hg, Pb and Cd in the Batang Kuantan River, Kuantan Singingi Regency has been carried out successfully. Heavy metals are measured not only from their heavy metal content such as Hg, Pb and Cd but also from the pH level of the river flow itself. The research location is at the Batang Kuantan River, which is measured from 3 points. Changes in Data Observed / Measured are the quality levels of heavy metals in the waters. The research model used includes field research using survey and laboratory methods. The research design was analyzed using the Atomic Absorption Spectometer (AAS). The water sample was given HNO3 until it was acidic and filtered so that there was no sedimentation, then analyzed by AAS. Heavy metal analysis result data technique is compared with quality standard of government regulation no 82 of 2001 regarding water pollution control and water quality management. Pb did not have a problem because the levels were not found. Whereas for Cu and Cd in the category of concentration threshold for reasonableness, which ranged from 0.158-0.1598 ppm and 0.0233-0.2769 ppm.

Abstract

This research is a quantitative study that aims to analyze the effect of ethical judgment on student behavior at the Kuantan Singingi Islamic University (UNIKS). The population used was students of the Tarbiyah and Teaching Faculty (FTK) with the sampling technique. Random sampling used SPSS. Data collection techniques use secondary data sources and pimer, for independent variables using secondary data sources by directly requesting the FTK UNIKS archive center, while the dependent variable uses primary data sources obtained directly from the original source through the Behavior scale. The test statistic needed to test the hypothesis is the correlation coefficient between the test score as a predictor and the score of a criterion. The interpretation of the analysis results in predictive studies is based on the betha index (β) or the b score in the regression model obtained. From the results of the study it was concluded that there was an effect of ethical judgment on the behavior of FTK UNIKS students with sig = 0.00 and F = 50.524, Y = 31.5 + 0.645X

Abstract

Basil is known to contain chemical flavonoids, namely orientin and vicenin where these two compounds can protect the body from the effects of radiation.The purpose of this study was to determine the toxicity of the ethanol extract of basil leaves (Ocimum Scantum Linn). Artemia salina Leach larvae using the Brine Shrimp lethality Test (BSLT) method. This study used 3 concentrations, each of which was carried out in triples. The concentrations are 1000 ppm, 100 ppm, 10 ppm. 90 Artemia salina Leach larvae were used. Then observations were made for 24 hours. Then counted the number of shrimp larvae that died after 24 hours. The results were calculated by probit analysis and calculated LC50, obtained LC50 = 21.0523 ppm. So it can be concluded that basil leaves have toxic potential. Because the value of LC50 < 1000 ppm.

Abstract

This research is the second research in the theme of Lesson Study-based Didactic Design. This research is based on the problem of learning difficulties and the low understanding of high school students on the concept of solubility and the solubility product constant. This study aims to make Lesson Design on the concept of solubility and solubility product constant in class XI SMA. This research was conducted at SMA Negeri 1 Singingi in class XI science and 2 chemistry teachers. The instruments used in this study were the TKR (Respondent Ability Test) questions, observation sheets and interview guidelines on the concept of solubility and solubility product constants. The method used in this research is a qualitative research method with a Didactic Research Design (DDR) approach. The research started from observation, interviews, and making TKR (Respondent Ability Test). The results of this study are the dissolution of the characteristics of the Learning Obstacle (LO) of students identified in the solubility concept and the probability of product being known. on the concept of solubility and the solubility product constant. Furthermore, the Learning Obstacles (LO) obtained were used to create online learning lesson designs during the Covid-19 pandemic.

Abstract

Papaya (Carica papaya L) is a popular plant in tropical regions such as as Indoneisa. whole areas of papaya from the root to the tio of the leaf, including the flower, fruits and seeds have good health benefits. Most studies see only the beneficial effects of the fruit and leaves, since they treat papaya seeds as waste have and are of no benefit. Papaya seeds are used as traditional remedies such as treating diarrheal diseases, skin diseases. Papaya seeds as an antibacterial that can kill bacteria by damaging the integrity of bacterial cells membranes. The papaya seeds are thought to contain a high level metabolic compound such a flavonoids, tokoferols, a terponoids that works as antioxidal in free radical counteract. Antiodants are substances that have small molecular weights that impede the oxidation reaction by promoting free radicals and highly reactive molecules that cause resistance cell damage. The study aims to determine the antioxidant activity on the extract of papaya seeds by using methanol by method of 2.2- diphenyl 1- picrylhidrazyl (DPPH). Research has shown that extract of papay methanol has IC50 of 872,0964 ppm indicates the antioxidal activity in papaya seed extract is very weak.
