Abstract
A country is said to be progressing, if all regions of the country prosper. In Indonesia, the smallest area that runs the government function is the village. The legal basis regarding the village government itself is stated in Law No. 6 of 2014 Republic of Indonesia. In carrying out its functions as a government, the village is supported by village funds. Village funds sourced from the state budget are intended for the development and improvement of the welfare of rural communities. Village funds can go down based on the proposal submitted. The proposal for submitting village funds is processed by a work team called Tim 11. So far, the determination of village funds is still manual and less transparent. Therefore we need a system that can overcome the problem of determining village funds. This research provides alternative solutions regarding the determination of recipients of village funds using the weight product method. There are four criteria in this research, namely the number of residents in an RT area, the standard of living of an RT area, the extent of the area, the level of geographical damage in an RT area. And the object of the research chosen was Kasihan sub-district, Tamantirto village. the results obtained are a priority submission in writing the proposal submitted.

Abstract
Electrocardiogram (ECG) signal is one of importance signal from our body that sourced from heart. There are many benefits that can be obtained from ecg signals, for example can determine whether sleepy or not, whether stress or not, and several diseasses like arrhytmia, hypertension, heart failure, etc. In this research, we proposed module for extraction feature for ecg signal to Heart Rate Variability (HRV) parameters using GPU Acceleration. The output can be used for further analytics or another module, but in this research only emphasis on QRS detection and peak detection from ecg signal. The input will be ecg Signals and the output will be array of peak in every row. There have been various research trying to extract or detect QRS and peak based on Pan-Tomkins Algorithm, but this research will make use python and will compare the acceleration using some library. The flow comprise five main step, (1) load ecg signal, (2) filtered ecg, (3) derivative from filtered ecg, (4) squaring from derivative ecg, (5) convolution squaring ecg, and (6) peak detection using Fiducial Mark. The output will list of array that contain mark for every peak in every ecg signal. The overall module has been succesfully implemented and compared in python. The result show that computation using numpy is still better and faster for small array data. The Output of peak of array can be used to the next module.

Abstract
The source of electricity in each university building in PGRI Semarang is obtained from each distribution transformer or power transformer. The power transformer used to distribute electricity in the central building (GP) has a capacity of 400 KVA, while the power transformer used in the main building (GU) has a capacity of 160 KVA. In the previous study, identification of the quality of electrical power in the PGRI University Semarang building, obtained a low power data factor and a large electrical network harmonics. The problem was solved by designing and installing bank capacitors and harmonic filters. To avoid dependence on PLN electricity and not using a generator when PLN electricity goes out, the source of electrical energy is designed by using solar energy sources through Photovoltaic. Solar Panel as an important component of solar power plants, converts sunlight into electricity. Generally we calculate the maximum amount of sunlight that is converted into electricity throughout the day is 5 hours. Electricity in the morning is stored in the battery, so electricity can be used at night, where without sunlight. Based on the identification of the load in the GP is 26.12 KW, then in the design using solar energy as many as 27 solar panels are needed. As for the storage system uses 44 batteries 100Ah battery. Off-grid solar panel systems are only used when PLN electricity goes out or can be used at night. The research method used is observing the amount of electrical load, calculating the capacity of solar panels and batteries, and simulating the model using a Power Simulator.

Abstract
Internet user is growing incrementally over the world. Most of them use mobile devices to connect the internet. They aim to stay in connection every time and everywhere. Thus, they use mobile IP communication to get always connected to the internet while they move to another place. Fortunately, the telco infrastructure has reached many places in the world. In addition, the video file transmission is now becoming a new trend especially a short movie transmitted via social media. The huge of the internet connection caused the scarcity of Internet address. This was anticipated by introducing IPv6 that supported the mobility by presenting the Mobile IPv6. This paper evaluates the performance on the MIPv6 mechanism on transferring video when the user moves to another place that usually different network infrastructure. Therefore, the vertical handover does not disturb the quality of the video transmission. The experimentation results show during the vertical handover, transmission packet loss less than 3% that categorized as good. Thus, the handover success ratio for all video format file reached 100%

Abstract
The high level of activity of internet users, which will have a negative impact on information providers. Requests from many users can cause performance capabilities on the web-server to decrease. The large number of requests results in crashes or overloads that have an impact on requests that cannot be served by a single server. Web balancing technology is needed so that the incoming request load is not only served by one server. Some scheduling algorithms that will be applied to web balancing testing in this study are round-robin and weight round-robin. In this study using ipvsadm as a means of making web balancing. This test aims to determine the performance of web servers when using web balancing technology by measuring the QoS parameters of web server services. The results show, the best value for measuring QoS parameters is responese time, request error, throughput, in the weight round-robin scheduling algorithm method.

Abstract
To construct beta converters with maximum efficiency it is necessary to carry out a theoretical calculation in order to determine their optimal parameters - the geometry of the structure, the thickness of the deposition of the radioisotope layer, the depth and the width of the p-n junction, and others. To date, many different theoretical models and calculation methods have been proposed. There are fairly simple theoretical models based on the Bethe-Bloch formula and the calculation of the rate of generation of electron-hole pairs, anf on calculations by equivalent circuits. Also, the Monte-Carlo method is used for theoretical modeling of beta converters. This paper explores beta converter optimization using the Monte Carlo method. The purpose of the study is to conduct a Monte-Carlo simulation of a beta converter to determine its optimal parameters.

Abstract
Final project is a prerequisite that must be taken by students to get a Bachelor or Master degree. Final project contains the results of research made in a specific format as reporting the research process to the institution. Each institution has a standard format for the final project or thesis writing rules which are usually written in the instructions for writing a thesis. Institutions usually provide writing templates to follow, but because the templates only make a number of important parts and are still manual, the format of student skiry writing often changes and is not uniform with other students or some are deviant and not in accordance with the standard written format. This study designed a text editor application to help students or researchers so that it was not too problematic in the writing format. This application is based on a graphical user interface, making it easier to operate. the rules in the program are made to automate the writing entered to produce written output in accordance with the format specified by the institution. With this system, student or researcher will be easier in writing the script according to the standard of writing and get a final project or thesis report in a uniform format.

Abstract
One stochastic process that is often used to model real phenomena is the compound Poisson process (CPP). CPP is a process in which a component in the process of the events occurred is assumed to be a Poisson process with a certain intensity function (homogenous or nonhomogeneous). Thinning process algorithm is usually used to generate events that occurred in the Poisson process. The study aims to find out the algorithm for generating the CPP which has nonhomogeneous Poisson process (NHPP) intensity functions. The value of the load caused by the Poisson process is assumed to be a family of i.i.d random variables and the variables are also independent of the Poisson process. The results of this study have obtained the thinning process algorithm and its generalizations for compound Poisson process having nonhomogeneous Poisson process (NHPP) intensity functions. This algorithm is the result of developing theory and computational simulation analysis by generating data that can be applied in various fields of science.
