Statistical reasoning through metacognitive brain-based learning

The low ability of students' statistical reasoning needs a promising learning innovation. The aim of this paper is to evaluate students' learning abilities through brain-based learning with metacognitive strategy. The Quasi Experiment Method, Nonequivalent Pretest-Posttest Control Group design, involved a sample of two classes of third semester students from Gunung Djati Swadaya University Cirebon. Instruments of this paper are statistical reasoning test and statistical preliminary knowledge tests. The result shows an increase in the ability of statistical reasoning among students who conducted brain-based learning with metacognitive strategy in the smart category, higher than students who applied expository learning strategy that only classified as the moderate category. Based on initial statistical knowledge (low, middle, and high) students who applied brain-based learning with metacognitive strategy, got a higher level than students who applied expository learning strategy. It shows interaction between the type of learning as well as initial statistical knowledge with the escalation of the ability of statistical reasoning. Brain-based learning with metacognitive strategy facilitates the process of conflict, discovery, social interaction, and reflective processes of students. Therefore, students abilities of statistical reasoning are better than expository learning strategy

The Study of Code-Mixing Phenomenon on the Trials Held by Madiun Military Court

This current research attempts to describe and explain the phenomenon of a speech event so-called code-mixing with military trials held by Madiun Military Court as the setting. The descriptions are based on (1) types and (2) factors attributing the code-mixing phenomenon. The source of data for this study is the utterances spoken by social components during the trials (juries, auditors, witnesses, victims, and defendants). Meanwhile, the data for this study are the application of code mixing. The data were collected through participative study method with noticing and recording technique. Meanwhile the secondary data of this study are the information related to the trials process obtained by conducting document study on official reports. In maintaining the validity, the current study employs method and data triangulation. The data were analyzed through interlingual and extralingual reference on the basis of Sociolinguistics. There are four lingual forms correlating to the code mixing namely (1) words (2) phrases (3) baster (4) and repetition. Those lingual realizations of code mixing are found to be attributable to four factors namely (1) habit (2) vocabulary mastery (3) humor (4) and interlocutor influence

Studies on the nephrotoxicity of silicon

Until recently it was generally accepted that the main source of exposure to silicon in man was the occupational inhalation of silica dust. Contrary to previously held belief silicates have been shown to be absorbed from the alimentary tract and that the kidney is the main organ of excretion of dietary absorbed silicon. In man renal functional impairment is accompanied by a fall in urinary excretion of silicon and a rise in serum silicon (Bobbie et al 1981). For the past 50 years there have been several reports on the nephrotoxicity of a variety of silicon compounds administered to experimental animals by several different routes. Moreover, there have been claims that acute or chronic exposure to siliceous dusts or prolonged intake of drinking water with a high silica content resulted in renal lesions in man. Secure in the belief that silicon compounds were nonabsorbable and non-toxic there has been an increasing use of silicates by the food and pharmaceutical industries as anticaking, antifoaming or hygroscopic agents. Thus recent evidence that silicates are absorbed and that the kidney is the main route of excretion raises a natural concern for the liberal ingestion of silicates by man in in view of the reports of nephrotoxicity in the experimented animal. Whereas, the few previous investigations of silicon nephrotoxicity have been rather limited in nature and inconclusive as to the nature of the pathogenetic mechanism, this investigation has attempted a study in depth while bringing to bear on the problem many new and different investigative techniques. This investigation has examined the renal effects of intraperitoneal injection of four silicon compounds to which man may be exposed. The intraperitoneal route was chosen since it was found to be the most convenient and reliable method, whereby the kidney could be exposed to different levels, of serum silicon. A series of acute experiments in rats determined that high serum silicon levels resulted in a tubulo-interstitial lesion, which was most pronounced in and around the distal tubule and collecting ducts. Extensive electron microscopic examination of the lesions revealed that the damage was manifest in gross swelling and oedema of the epithelial cells and their cytoplasmic contents. A marked acute inflammatory response in which eosinophils were prominent accompanied the lesions. Significant glomerular pathology did not result from acute silicon nephrotoxicity. All four silicon compounds tested produced a similar degree of renal damage. Three different, but complementary techniques were then used to demonstrate the concentration and localisation of silicon in the kidney in the acute experimental model. Atomic absorption spectroscopic (A.A.S;) measurement of silicon in ashed samples showed an early and rapid rise in renal tissue silicon concentrations in contrast to a slower accumulation in other organs. The rarely studied radioactive isotope of silicon, 31Si which was specially made in an atomic reactor for this investigation, confirmed the A.A.S. findings while additionally providing autoradiographic studies which showed silicon concentration in the distal tubule.

Efektivitas Air Rendaman Jerami Alang-Alang (Imperata cylindrica) sebagai Atraktan terhadap Jumlah Telur Aedes aegypti

The use of ovitrap with attractants modification has been known as an alternative method in controlling DHF vectors. Attractant material will be better if it uses natural ingredients that are cheap and easy to obtain and easy to manufacture. Attractant material is recommended to use natural ingredients that are cheap and easy to obtain and are easy to make. Imperata plants can be easily obtained and easily processed as attractant material. This study aims to determine the effectiveness of attractants on a laboratory scale in the form of immersion water from the straw of the Imperata cylindrica plants in various concentration levels to Aedes aegypti eggs number. Research with an experimental design using a completely Randomized Design (CRD) was conducted at the Entomology Laboratory of the Tanah Bumbu Research and Development Center, in July 2019. Treatment concentrations consisted of 5%, 10%, 15%, and 20%, control using akuades. Samples for testing using Ae. aegypti gravid mosquitoes. Treatment with 5 repetitions, carried out for 7 days. Data analyzed by normality test, Anova test, and Least Significant Differences (LSD) test. The average number of eggs at concentrations of 5%, 10%, 15%, and 20% respectively was 45.00; 78.60; 129.40; and 174.00. Anova test showed Imperata cylindrica straw soaking attractant had a significant effect on oviposition of Ae. aegypti mosquitoes. LSD test results showed attractant 15% is the optimal concentration in increasing the number of eggs in the ovitrap
