Abstract

Weather is an atmospheric condition that occurs in a narrow area with a short space of time. Observations of weather elements are needed in everyday life. for it can affect the safety of air transportation. The weather element that is often predicted is rainfall. Rainfall in tropical regions such as Indonesia is one of the parameters that can describe weather conditions in general. The method used to predict rainfall was artificial neural network with backpropagation algorithm. The purpose of this paper is to apply the model of artificial neural networks with backpropagation algorithm to predict daily rainfall and to determine prediction accuracy based on Mean Square Error (MSE). The network used has 3 layers namely input layer. hidden layer. and output layer with 7 input neurons, 12 hidden neurons, and 1 output neuron. The activation function used were bipolar sigmoid function and linear function. Based on data analysis carried out using network architecture and parameters that had been determined with 578 data at the training stage. MSE values of 25,0639 was obtained  and based on the results of the network training process. the prediction was quite well. In the testing stage. the model developed using data as much as 145. MSE value of 405,1994 was obtained. MSE obtained during the testing stage was greater than that of obtained during the training process due to several factors. one of them is because the weather is volatile so the weather conditions vary every year and global warming causes weather conditions to be unpredictable.

Abstract

International Standard Book Number or ISBN is a code that contains information about the title, the publisher, the different types of materials for making the book, and publisher group from a book. The ISBN code of a book along with its development need to be checked for validity, because the more books are published, the more chance the book will be copied so that it has a double ISBN number. This research show that the use of modulo arithmetic in arranging ISBN for a book, especially ISBN-10 and ISBN-13. In this research too discussed about validation ISBN-10 and ISBN-13 using modulo arithmetic and expanded by developing an ISBN-n, for a natural number n greater than 10. Validation will be carried out in two stages, namely manually using modulo arithmetic calculation and then computing, by compiling java-based application to validate an ISBN. The development of ISBN-n for n ∊ ℕ and n ≥ 11 use the advantages of ISBN-10 and ISBN-13 and (Memorandum of Understanding/MoU) ISBN agency. Case studies in the Department of Library and Archives of West Nusa Tenggara Province on the ISBN validity of additional collection books for the 2015-2016 period showed that the ISBN validity of these books is 96%.

Abstract

The pipeline network is one of the most complex optimization problems consisting of several elements: reservoirs, pipes, valves, etc. The pipeline network is designed to deliver water to consumers by considering the demand and adequate pressure on the water pipe network. The main problem in designing reliable pipelines is the cost. The amount of cost that most influences the design of pipelines is the diameter of the pipe used. Therefore, this study aims to combine (hybrid) simulated annealing algorithm with genetic algorithm to optimize water pipe networks. The simulated annealing algorithm is the main algorithm in finding the optimal cost.Meanwhile, the genetic algorithm will assist in the pipeline update process using the roulette wheel selection. Simulation data is used to test the hybrid algorithm performance compared to the standard simulated annealing algorithm. The results show that the simulated annealing hybrid algorithm is able to get a more optimal cost in designing a water pipe network compared to the standard simulated annealing algorithm. Keywords: Optimization, Epanet 2.0, Simulated Annealing, and Genetic Algorithm

Abstract

The COVID-19 pandemic has affected various aspects of life in Indonesia, one of which is the education sector. For example, during the COVID-19 pandemic, most junior high school teachers, especially at the Islamic Junior High School Pondok Pesantren At-Tamimy, only used textbooks as teaching materials which of course were less effective and interactive. Therefore, this Community Service (PkM) activity aims to introduce teachers at the Islamic Junior High School Pondok Pesantren At-Tamimy with interactive e-modules for online learning using Canva. The results of this activity indicate that the implementation of this Community Service Activity has been running quite well and smoothly. Through this workshop, the teachers of the Islamic Junior High School Pondok Pesantren At-Tamimy were given tutorials on making interactive e-modules which can actually not only be used in the online learning process during the COVID-19 pandemic, but can also be used for more efficient, effective offline learning. and fun because teachers can be creative in making e-module designs as attractive as possible for students. Based on the explanation of the results of the implementation of this activity, it can be concluded that the team has carried out the workshop well, smoothly, and fun because teachers can be creative in making e-module designs that are as attractive as possible.
