Abstract This study aimed to analyzed market reaction caused  the announcement of rising dividend or dividend down before and after Ex-dividend date in Indonesia Stock Exchange (IDX).This research used event study method by using abnormal return on share as research variable and used price data of shares as research unit analysis. As the result, 26 companies as the sample of 45 companies which registered in index LQ45 in Indonesia Stock Exchange period 2016-2018 by purposing sampling technique. Measurement of variable using the calculation of the average abnormal return of shares by testing the hypothesis using different test paired sample t-test and Wilxocon related sample test with the help of SPSS version 22.The research result showed there was no difference in abnormal return on share before and after Ex-dividend date in the companies which announced rising dividend and dividend down in Indonesia Stock Exchange (IDX) period 2016-2018. The results of the different paired sample t-test obtained a significance value of 0,486 which was greater than 0,05 and in the Wilxocon test the related sample test obtained z score of 1,478 which was greater than z table which was 1.458. For the next research, it is recommended to test the different indexes and regard to the confounding effect which can lead to bias.Key words: Dividend, Abnormal Return, Ex- Dividend date, Event StudyAbstrak Penelitian ini bertujuan untuk menganalisis reaksi pasar saham yang ditimbulkan oleh  pengumuman dividen naik atau pengumuman dividen turun sebelum dan sesudah ex- dividend date di Bursa Efek Indonesia (BEI).

      This study aims to determine the effect of the Type STAD Cooperative Learning model on mathematical problem solving abilities. The data collection technique was obtained by means of a test in the form of description questions and documentation in the form of a list of student names. The research instrument used was 3 pre-test and post-test questions. The data analysis technique used is the normality test, homogeneity, t test with the technique of paired samples t-test and independent t-test.      The results showed that, the paired sample t-test on the problem solving ability before and after treatment with STAD obtained an average value of 50.29 to 83.71 with a significance of 0.000 <0.05. This means that the students' scores before and after STAD learning have differences in the average mathematical problem solving abilities. Based on the results of the paired sample t-test on the ability to solve mathematical problems before and after treatment using conventional learning models, the average value was 44.57 to 75.79 with a significance of 0.000 <0.05. This means that there is a significant increase before and after conventional learning. Based on the results of the independent samples t-test, the mean values were 83.71 and 75.79 with a significance value of 0.009 <0.05. This means that there is a difference in the average problem-solving ability of students in STAD learning with students in conventional learning. It can be concluded that the STAD type of cooperative learning model has an effect on students' problem solving abilities in mathematics.

Abstract: Chloride as the major anion in the extracellular fluid plays a role in maintaining fluid and electrolyte balance. One of the factors that influence the levels of serum chloride is sweating during physical exercise. This study aimed to determine  the differenceof serum chloride levels before and after moderate intensity exercise in the students of Faculty of Medicine year 2010 Sam Ratulangi University. This is a pre-exsperimental research with pretest and posttest design with 30 students as samples. The samples were chosen using purposive sampling method and the results were analyzed using paired-sample t-test. The results showed the average levels of serum chloride before and after moderate intensity exercise are 106,10 mEq/L and 107,37 mEq/L while paired-sample t-test significance value (p) is 0,000. From the results can be concluded that there is a significant differences in serum chloride levels before and after moderate intensity exercise in the students of Faculty of Medicine year 2010 Sam Ratulangi University. Keyword: serum chloride, moderate intensity exercise, student of Faculty of Medicine Sam Ratulangi University   Abstrak: Klorida sebagai anion utama dalam cairan ekstraselular berperan dalammemelihara keseimbangan cairan dan elektrolit.

Purpose of this study is to predict trend value of collecting ZIS with fintech and non fintech. Data taken from BAZNAs from 2002-2017 and using descriptive statistics with linear trend and parabolic, inference statistic with paired sample test. Result shown that fintech trend like parabolic and non fintech like linear. There is a significant and power full correlation at ZIS revenue with fintech and non fintech. Thus, there is difference average of ZIS revenue before and after using fintech. Using SIMBA fintech will be affecting the revenue of ZIS. Average prediction of ZIS collecting funds from 2018-2025 with fintech is greater than using non fintech. Average growth of ZIS revenue with fintech is 9.98 percent and 5.78 percent with non fintech.
