Although not all tax planning actions are carried out illegally, the more loopholes a company uses to avoid taxes, the more aggressive the company is considered. And this study aims to examine the relationship between the dependent variable and the independent variable of this study. The independent variables are liquidity, ROA, leverage and firm size and the dependent variable is tax aggressiveness. And for the analytical method used is regression analysis, and descriptive analysis. Descriptive statistics are used to describe or describe the variables in the study. Descriptive statistics used are measures of tax aggressiveness of all sample companies. The description of the variables can be seen from the mean and standard deviation. The descriptive statistical test was carried out with the SPSS program. The results of the study found that liquidity has no effect on tax aggressiveness, then Renturn on Assets (ROA) affects tax aggressiveness, then leverage affects tax aggressiveness and company size affects tax aggressiveness.   Keywords: Liquidity, ROA, Leverage, Company Size, Tax Aggressiveness

Mathematics is an applicable science and very close to human life, so mathematics is very important to learn from elementary school. However, the mathematics competence of elementary school students in Indonesia is relatively low. One of them is SD IT Cahaya Ummat which is located in Karangjati, Kecamatan Bergas, Kabupaten Semarang, the grade 6 students' average mathematics score is lower than other subjects. So far, learning is still conventional in nature with learning resources in the form of printed books, thus it is necessary to have learning innovations to increase students' interest in learning mathematics.The design of interactive media as a learning aid can be a solution to attract students' attention to be more focused when the teacher explains math material in class. When students feel interested and focused on learning, learning will be more effective so that students' understanding of the material presented by the teacher will also increase.Interactive learning media made with Adobe Flash CS5.5 to combine text, images, sound, and animation will make the application more attractive, so that students are more interested in learning mathematics with statistics material. The results of the validation score obtained from media experts are 34, material experts 39, and users 35, so this learning media product is classified as a very good category, so it is valid to be used.  

The development of computers in the current era can help teachers improve human resources (HR), especially in the field of education. SPSS and Excel are statistical applications that can process teacher research data such as education management data and classroom action research data and so on. This community service (PKM) is carried out in the form of statistical application training (SPSS and Excel) as well as writing techniques and publication of scientific articles. Participants in this activity consisted of 21 teachers and employees of the Muhammadiyah Mamala High School in Central Maluku. The conclusion obtained in this activity is that activities that have been carried out in the form of training are considered very good (99%). All material that has been planned can be delivered, although due to time constraints there are some materials that are only presented in an outline. The participants' ability in mastering the material was considered very   1Jurusan Matematika FMIPA Universitas Pattimura, Ambon-Maluku         good (98%). This is based on the teacher's ability in training and trials in the form of classroom action research data processing using Excel and SPSS applications. In addition, from the results of the training given to the participants, it was found that all the training participants perfectly mastered the tasks given in the training.

Study This goal is to ascertain how return on investment affects the share price of PT Astra International. Time frame for the study: this covers the years 2013–2018. population studied This is a mining company that is listed on IDX. Purposive sampling is used in the election sample. In the years 2008 to 2010, there were up to 31 firms miningyang listed on the IDX. utilized data analysis Simple regression analytical techniques are used to test the hypothesis.According to a results study, the results mark significance of 0.935 acquired by results processing statistics is larger than the criteria significance (0.05). The regression model is therefore not significant. Therefore, the linearity criterion is satisfied by linear regression. The R2 result is 0.002 which indicates that the variability variable dependent may be described by the variability variable independent by 0.2% while the remaining 99.8% is explained by other factors not included in the regression model.

Workload is the ability of the worker's body to accept the job. From the standpoint of ergonomics, every workload received must be appropriate and balanced against the physical and psychological ability. The good Response time for patients is <5 minutes. Handling of emergency is the whole act performed in emergency conditions that are effectively and efficiently. The purpose of this study was to determine the relationship workload response time nurses with nurses in emergency departments of RSUD Bitung General Hospital. This study was descriptive and cross sectional study. Samples were taken based on the number of respondents as many as 31 nurses by using total sampling. The data collection is done by filling out the observation sheet and questionnaire. Furthermore, the data that has been collected processed with the aid statistics analyzed by chi square test with significance level is ? = 0.05. After the results, the value of p = 0.008, this may imply that there is a relationship between the workload of nurses response time. CONCLUSIONS of this study found that there is a relationship between nurses workload response time. Suggestions for the research was taking place is setting a good system including facilities and infrastructure in order to nurse response time can be improved.
