Abstract

Optimizing customer service for the number of drivers in an area through real-time transportation service industry online to scale up. In this paper, the dataset used is traffic management accompanied by attributes such as level 6 geohash, day, timestamp, and demand. The dataset used is a sample from geohash6 coded qp0991, containing online transportation demands from 01/04/2018 until 31/05/2018 (61 days). The training datasets are from the qp0991 code sample, starting from 01/04/2018 until 10/05/2018 and the remaining datasets are used as the testing datasets. The percentages for training and testing are respectively 67% and 33%. The methods applied to construct the objective function are three different forecasting methods, namely the Naïve approach, auto-regressive integrated moving average (ARIMA), and simple exponential smoothing. The results of this study indicate that the simple exponential smoothing method is better than the naïve approach and auto-regressive integrated moving average based on the root mean square error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE). The simple exponential smoothing has an accuracy rate of 98.7% for the RMSE value, 98.9% for the MAE value, and 88.81% for the MAPE value. Keywords: time series, traffic management

Abstract

This development research aims to describe the quality of learning media for Student Worksheets (LKPD) with a contextual approach to class VIII statistics material. The quality of development products is assessed based on: 1) aspects of validity, 2) aspects of practicality, and 3) aspects of effectiveness. The learning media development procedure refers to the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. The subject of this study was a student of class VIII MTs Bahrul Ulum Blawi Lamogan. The instruments used to obtain data on the quality of the learning tools developed are: 1) LKPD validation sheets to measure validity, 2) questionnaires of student and teacher responses to measure practicality, 3) tests of student learning outcomes to measure effectiveness. The results of this development research show that the quality of the validity of learning media meeting the very valid criteria is indicated by an average score of 3.50 by media experts and an average score of 3.27 by material experts from a maximum score of 4. The quality of practicality of learning tools meeting practical criteria is indicated by the average student response score of 3.01 from a maximum score of 4, the average score of teacher responses which is 3.43 from a maximum score of 4. The quality of the effectiveness of learning tools is seen from the results of student learning tests with a percentage of student completion.
