Abstract

Scheduling is one of the most needed requirement for high school. Scheduling at brawijaya smart school senior high school(BSS SHS) had some problems like processing time, schedule size, Musyawarah Guru Mata Pelajaran(MGMP), and managing variety subjects. Scheduling took 3 days to be done. Problem space's size is 834 hours of subject. Teacher's schedule cannot crashed with MGMP. Variations of teachers and subjects cannot be the same within a day from those problems above researcher will use genetic algorithm to solve them. Genetic algorithm is an algorithm that can be used to get the solution that closed to optimum from the wide possibility solution area. In this research, researcher used partially-mapped crossover, reciprocal exchange mutation, and elitism selection. The result gets that the 233rd generation, 150 population size, 0,7 crossover ratio, and 0,3 mutation ratio are the most optimum solution parameter in BSS SHS scheduling case. This research has its disadvantage in early convergence that happened at 233rd generation so random injection is needed to be applied. Global and local search aren't effective because searching ratio is always the same. Population size was too big that difficults the searching for the best parent so parent selection needed to be applied.

Abstract

Rainfall is the height of rain water that is found and collected in a flat, not absorbed, does not evaporate and does not flow. Information about rainfall is very important especially in agriculture and civil. In agriculture, rainfall information is used to determine the type of plants to be planted in accordance with the intensity of rainfall, predicting the start of the growing season in the planting calendar to minimize the risk of planting. In the civil field, it is used as a determinant of engineering design standards in planning flood disaster control buildings. Above normal rainfall will cause natural disasters such as floods and landslides. Rainfall is part of the weather element and one of the meteorological processes that is quite difficult to predict. Rainfall forecasting is needed so that the community and the government can take preventative measures against the existing problems. The forecasting process is divided into several processes which include data normalization, forecasting with the Extreme Learning Machine algorithm, data denormalization and the results of errors with MAPE. Based on the test results using rainfall data in the Poncokusumo area with a span of years 2002 to 2015 obtained the smallest MAPE value of 3.6852%, with as many features as 4, many neurons in the hidden layer as much as 2, the percentage of training data 90%.

Abstract

Tourism is one of the important aspects contributing to income for the country, especially Singapore. Singapore is ranked 2nd on the Asian continent and ranks 13th in the world in the tourism sector. One of Singapore's state revenue generated in the tourism sector is 14.8%. More than 16 million foreign tourists come to Singapore every year. However, the number of tourist visits has increased and decreased every month. Changes in the value of the fluctuations can lead to less than the maximum tourism industry in Singapore, especially the infrastructure sector. Because the accommodations are limited in accommodating a large number of tourists. Therefore, a prediction of the number of tourist visiting to the country of Singapore is needed, so that it becomes material for consideration in preparing better accommodation. One prediction algorithm that can be used is Extreme Learning Machine (ELM). From the results of the research that has been done, the optimal algorithm parameters on ELM are, the number of feature data = 5, the ratio of training data and testing data = 80%: 20%, and hidden neuron = 10 with the data on the number of tourist visiting in January to December from 2010 to 2016, the error value obtained using MAPE was 7.41%.

Abstract

Mobility is the movement from one place to another, where in the implementation of mobility requires a tool that can support. The field associated with mobility is transportation. The use of transportation is applied in MI Salafiyah Kasim as a solution to ease the burden of guardians. Because the guardian can not every day pick up their children from school, especially the age of students who are still very young and worried about having to go or go home from school alone and distance of school and home far enough. Optimization of the school's own private transportation will be expected to bring the optimal solution to minimize constraints, such as: lack of efficiency in delivery times, traffic accidents, to save the school budget. Ant Colony Optimization (ACO) is the preferred algorithm for optimizing Travelling Salesman Problem (TSP) problems. In this research, the data is the distribution of kloter delivery of students to homes divided by 2 kloter. Where the total number of students is 44 people, the first group of 20 people and the second group of 24 people. From the test results obtained best optimization was 5,711 km (22,71%) on first cluster and 34,5551 km (62,14%) on second cluster.
