Abstract

The purpose of this study is to determine whether there are differences in the skipping exercises and the bench step-up on the leg muscle explosive power of members of Participants of extracurricular futsal Bina Darma. The research method used an experimental method with a two-group pretest-posttest design, a population of 24 people, and a sample of 12 people in the skipping exercise group and 12 in the bench step-up exercise group using the MSOP technique. The pre-test and post-test test instruments used a standing broad jump. Data analysis used t-test difference (paired t-test). The results showed a significant difference in skipping exercises and the bench step-up in generating leg muscle explosive power in Bina Darma university futsal club participants (F-count 4,620> F-table 3,98). The percentage of skipping training on the explosive power of the leg muscles was 26%, and bench step-up training was 63%, so the difference between the two was 37%. Still, it was inseparable from the limitations that existed during the study, namely: 1) The sample was not in a dormitory, so there might be some who practiced alone outside treatment 2) In this study, the subjects studied were still very few, limited to the men's futsal extracurricular members of Bina Darma University Student Activity Unit. 3) The researcher cannot control other factors that may affect the test results, such as body condition, psychological factors, and so on. Suggestions for the trainer or teacher; they should provide more varied exercises as an effort to increase the explosive power of the leg muscles and further research is needed by adding other variables.

Abstract

The application of data mining technique currently is widely used in supporting business activity, especially for insurance company which has to analyze a big number of customer data. The insurance company has to predict its new customer acquisition as well as maintain its existing customers. This paper is focused on how we support insurance companies, especially PT. XYZ, to analyze their customers’ characteristics data using the best data mining algorithm technique. The research aims to analyze existing customer data and to predict as well as find optimal patterns of how many of their customers will extend their insurance policies, and how many will not. We also explore the customer retention rate discovering the optimal solution for the company. We applied 4 different algorithms were applied, i.e. support vector machine algorithm, decision tree, k-NN, and random forest algorithm, comparing the results and finding a better solution. From the analysis, we found that the random forest algorithm provides better results in predicting the status of the insurance policy extension of current customers, with an accuracy rate of 91.08% and AUC value of 0.962. This result is quite good for PT XYZ, and could be enhanced in the future by applying a good strategy to increase their customer renewal ratio.

Abstract

Complex training is an exercise method that combines plyometrics with strength training. This exercise is an exercise used to increase muscle power. This study aims to determine the effect of training of complex training methods towards leg muscle power and arm muscle power for adolescent volleyball athletes. The method used in this study is an experiment with a control group pretest - post test design. Subjects in this study are 23 adolescent volleyball athletes (14-17 years old) with 12 males and 11 females, who are divided into two groups of experimental groups (n = 12) and control groups (n = 11) with randomized matched pair design based on the ranking of the vertical jump ability. Instrument used in this study is vertical jump test (leg power) and the medicine ball throw test (arm power). The data analysis technique uses the paired t-test with a significance level of α = 0.05. The results show that training using a complex training method provides a good benefit in improving leg and arm muscle power. Therefore, this method is appropriate for used by adolescent volleyball athletes that have had experience of weight training in improving muscle power towards adolescent volleyball athletes
