Abstract
In this study a prototype of a Hybrid Power Plant (PLTH) will be built that integrates the Pico-hydro Power Plant (PLTPH) and the Solar Power Plant (PLTS). The prototype of the PLTH to be built has a capacity of 500-1000 watts. From the making of the prototype-1 it was discovered that the PLTPH produced a maximum power of 86 W (from a capacity of 100 W) and the PLTS produced a maximum power of 30 W during bright weather and 23 W when the weather was dim (from a capacity of 100 W). The results of testing on prototype-2, it is known that PLTPH with a capacity of 600 W produces maximum power of 257.48 W and PLTS with 3 x 200 Wp (watt-peak) solar panels producing maximum power of 176.4 watts. After some adjustments, the electrical energy from these two sources is then stored in the battery. Electrical energy from PLTS is stored on the battery after going through the MPPT Solar Charge Controller; while the electrical energy from the PLTPH is stored on the battery after the electricity voltage is lowered and rectified with the rectifier. From the results of observations and measurements during testing, these two sources of electrical energy can charge the battery normally. Electrical energy from batteries that are direct current electricity is then converted into electrical energy alternating current of the power frequency to be supplied to the load, especially the electric load of alternating current.

Abstract
In this paper we developed insurance model on property rental business. We used Generalized Linear Models(GLM) to develop this model because the data on property rental matches to the characteristics of GLM. Analysis of the model is done by looking at the relationship between the distribution functions that are most widely used in the analysis of property rental data. The models for the relations of distribution functions are: Poisson-Gamma, Poisson-Inverse Gauss, Negative Binomial-Gamma and Negative Binomial-Inverse Gauss. The relationship between distributions is seen from the root-mean-squared error (RMSE) and absolute mean error (MAE). Simulation results show that the model formed in the case of random effects increases in standard deviation values also increases the variation value on the average estimator. This is in accordance with the condition that the addition of standard deviation means that there is an increase in the variance of the data.

Abstract
This study aims to develop learning media for 3-dimensional object modeling video tutorials that will be used in 3-dimensional animated learning on graphic design extracurricular activities at Al-Azhar Bumi Serpong Damai Islamic High School, as well as to find out the feasibility of learning video tutorial media. The 3-dimensional object that will be created is the Iron Man mask. Making 3-dimensional objects using Blender software version 2.79b, while for making tutorial videos use Camtasia software version 8.6.0. The concept of developing video tutorials uses the R & D (Research and Development) method with a development model from the Ministry of Education (2004) in Andi Prastowos book. The stages of development are: (1) making a title, (2) making a synopsis, (3) making a script, (4) taking pictures, (5) editing videos, (6) expert testing, (7) distribution and (8) evaluation. After the media video tutorial is complete, the next is to test the tutorial video for respondents, namely class X and class XI participants of graphic design extracurricular activities at Al-Azhar Bumi Serpong Damai Islamic High School. The results of the respondents trials were scored 84.86%. With details of the aspect of display quality / impressions 86.5%, aspects of interest and attention 74% and aspects of accuracy of material content 87%. Based on the results of these tests, it can be concluded that the learning media (tutorial video) makes Iron Man characters worthy of being used in learning 3-dimensional modeling material on graphic design extracurricular Al-Azhar Islamic High School Bumi Serpong Damai.
