Abstract

Zero-Inflated Negative Binomial (ZINB) regression is one of the methods used in troubleshooting overdispersion due to excessive zero values ​​in the response variable (excess zeros). ZINB regression model was based on the negative binomial distribution resulting from a mixture distribution between Poisson distribution  withis value of random variable which gamma distributed. ZINB regression parameter estimation can be performed by using Maximum Likelihood Estimation (MLE) method then is followed by the EM algorithm (Expectation maximization) procedure and Newton Rhapson. Test the suitability of the model simultaneously performed using Likelihood Ratio test and significance testing parameters individually performed with Wald test statistics. The model is applied to the case of car insurance obtained PT. Insurance of Sinar Mas Semarang Branch in 2010 in the form of data many policyholders filed claims to the PT. Sinar Mas Semarang Branch Insurance. Response variable is the number of claims submitted to the PT. Insurance of Sinar Mas Semarang Branch, while the predictor  variable is the age car and the type of coverage that consists of All Risk, Total Lost Only (TLO), and the joint between All Risk and Total Lost Only (TLO). From the analytical result obtained the conclution that the age of the car and the type of coverage affects number of claims filed by the policyholder to the PT. Insurance of Sinar Mas Semarang Branch in 2010.

Abstract

The purpose of this study is to develop a multimedia-based edutainment to increase interest and learning outcomes student in vocational school in linear program material. This type of research is development research with ADIE model. The purpose of research is to produce multimedia products are valid, practical and effective. The research was conducted from 21th of November 2016 until 3th of December 2016 and held at SMK-PP N Kupang. Trialling performed twice. The first trial conducted to seek advice and input from students as users of the product while the second trial was conducted to see the practicality and effectiveness of the product. The results show that the development of products developed are valid (average score validation of all the validator is 4.18), practical (average score of questionnaire responses for all students is 2.81), and effective (average questionnaire student's interests is 8,9 and there is an increase compared with the end of the test to the early test).
