Abstract

The prospective cchemistry teachers student should be free from the burden of misconceptions before graduating and take part in society. Researchers opinions previously stated that students who have the ability to think logically high that students typically high levels of cognitive conflict. Analogy of the statement, it means that students with higher levels of cognitive conflict, the burden misconceptions is low, even free from the burden of misconceptions. Expenses misconceptions known to provide misconceptions detector test in the form of questions that have been analyzed using the theoretical analysis of the concept of Herron. The concept is used as a detector test misconception here is the concept of chemical solutions. Detector test misconceptions coupled with a test of confidence in the results of the demonstration and testing of the levels of cognitive conflict is used to detect the level of student cognitive conflict. Showed that prospective teachers student in 7th semester chemistry Unesa was 98% had misconception loads and 84% of which have high levels of cognitive conflict moderate to low. The results show that students who have a high level of cognitive conflict is not necessarily free from the burden of misconceptions.

Abstract

Mother and Child health education in general is still mostly done through individual or case-by-case consultations given when the mother checks the womb or during the posyandu activities. Counseling given is not coordinated so that the knowledge given to mothers is only the knowledge possessed by officers only. To overcome these weaknesses, a method of learning for pregnant mothers is carried out using the MCH Handbook and class turning sheets of pregnant women in the form of face-to-face meetings in groups followed by discussion and exchange of experiences between pregnant women and health workers. As planned, identification has been carried out for pregnant women with gestational ages 8 weeks to 36 weeks of 11 pregnant women. The meeting was held at Lorulun Village Hall. The results are a) A class of pregnant women is formed in Lorulun Village with 11 participants, between 8 weeks and 36 weeks of pregnancy, b) 11 pregnant women in Lorulun village have a MCH book, c) Based on pre-test average results is 47% and the average post-test result is 82%, and d) A total of 5 pregnant women aged 20 weeks to 36 weeks who carry out puerperal exercises, while 6 pregnant women do not carry out pregnancy exercises because the gestational age is below 20 weeks .

Abstract

The aggregate usage of nature that continually taken or used for the manufacture of concrete mix for civil building construction work can impact for its availability in nature. By him it was one of the alternatives to reduce the intensity of natural aggregate consumption is by utilizing waste concrete shards as fillers in the concrete mix. Self Compacting Concrete (SCC) is very fresh concrete and easy flowing because plastis weight itself fills the whole mold due to the concrete properties to condense on its own, without the help of the vibrator to compaction. Compressive strength of concrete calculated based on the formula, f'c = P/A. Research done with the experimental method, where compressive strength testing done when the concrete was 3, 7, and 28 days. Waste fractions plus concrete into concrete mix SCC with two variations, where variations of the one using 100% of waste fractions of concrete aggregate in lieu of coarse concrete mixtures in SCC, two variations using 50% of waste fractions of concrete and 50% rock burst in the concrete mix SCC. Each variation uses 3 cylindrical test objects with a diameter of 15 cm and a height of 30 cm for 3, 7, and 28 days. The research results show compressive strength of concrete median age 3 days for a variety of one and two respectively 12,88 Mpa and 14,42 Mpa, and at the age of 7 days of compressive strength of concrete average increased to 18,65 Mpa and 20,57 Mpa, and at the age of 28 days and a powerful compressive strength of concrete median to two variations of usage of waste fractions concrete increased by 28.07 Mpa and 30,77 Mpa.

Abstract

Learning in the new normal era during the co-19 pandemic will certainly be different from previous learning. Long before covid-19 learning was free to learn individually or in groups, but in this new normal era learning only focused on individuals without group assignments. So from that the purpose of this study is to find out how much the level of effectiveness of learning on student learning outcomes with high interpretation expectations. The method used in this study is a quantitative approach where data is obtained by statistical tests which are assisted with the application of SPSS for windows. The data is accumulated and analyzed by regression analysis so that after a statistical calculation is obtained a value of 73,2% in which a value of that size can be interpreted quite well or it can be said that learning is quite effective in the new normal era.

Abstract

Ebony is a luxury wood that grows endemic to Pulau Buru Maluku with the name Ebony Maluku while the other local name is the wood of Belo Hitam (Diospyros sp). Eboni is one type of wood that is very much liked by the community and the existence of quite a lot on the island of Buru, but the information about its basic nature is not well known by the local community. The study aims to determine the influence of the wood vertical position (base, middle, and end) and anistropic (radial tangential) areas of the wood physics properties of ebony. The results showed that the moisture content of three parts varies from the base of the stem to the end, while the highest wood density in the trunk is the base, then, the end, and the low at the center. The timber depreciation on three anistropic surfaces indicates the largest depreciation in the tangential field compared to radial

Abstract

Regression analysis method is one of the statistical methods used to describe the relationship between two or more variables, so that a variable can be predicted from another variable. In regression analysis there are two types of approaches, namely parametric and nonparametric approaches. Estimates used to estimate the parameters in the regression analysis using the OLS method. This method is based on the mean distribution, so it is not appropriate to analyze a number of data that are not symmetrical or contain outliers. Therefore, a quantile regression method and kernel smoothing were developed that were not affected by data containing outliers and could also be used as an alternative to solving fluctuating data problems. This study uses quantile regression with kernel smoothing in the case of factors affecting malaria in Indonesia. The results show that the main factors causing the spread of malaria in Indonesia are access to proper sanitation, household factors that behave in a clean and healthy life, and the number of puskesmas and the percentage of medical personnel.
