Abstract

Learning or material on processing waste to produce electricity is needed because demand for electricity increases, while uncontrolled trash. Uncontrolled increase in litter causes uncontrolled pollution in the air anyway. Coupled with the fossil fuel emissions that are contributing to pollution and environmental pollution are greatest. Processing environmentally friendly fuels such as waste must be developed. Learning about the waste that exists today only still lacking and is still text-based or in book form. This leads to a lack of public interest to learn the material on waste management. The existence of this application, a solution to these problems. This application is designed in the form of exciting multimedia learning so as to increase public interest in the field of waste management. In addition in the form of multimedia, this application is also easy to operate, because the location and navigation menu uncomplicated. Waste processing in this application refers to the existing landfill gas systems in Power Plant Waste (PLTSa) Bantargebang.

Abstract

Instructor is the main aspect that exists in the implementation of the training. The increasing number of instructors and the need for training is also increasing every year there is no system that can help the process of determining quickly and precisely. In need of a method that can classify the instructor data in accordance with the title of training materials and can be assigned instructor each of the training materials and do not ignore aspects of assessment of the instructor. In this study data mining techniques are used to help recommend instructors for each subject matter of the training based on the cluster data group approach. So it can be used in determining the instructor's assignment per training materials in the future. K-Means clustering method is used to group data into clusters by looking at the centroid value that has been determined. And the Topsis method is used to assign one instructor's name through the rankings of preference values. In this research CRISP-DM method is used as software engineering method system work done in sequence or linearly. In the testing process has been generated if the manual data and data processing if the application system is the same. This application to facilitate the Supervisor and Learning Development staff in setting instructors per training materials.

Abstract

The purpose of this study is to predict HbA1c in diabetics. The obstacles behind the prediction of HbA1c is the limitations in the laboratory to provide services for diabetics regarding HbA1 check-up. HbA1c prediction is made by a combination of K-Means and C4.5 methods. K-Means is used to classify continuous data. From the results of the K-Means classification will be used by C4.5 to create a rule (decision tree). The prediction results obtained will be carried out as a validation process to determine the level of accuracy by using K-Fold Cross-Validation. The accuracy value obtained is 72%. The resulting benefit from the prediction of HbA1c can be used as an alternative solution to overcome limitations in the laboratory in terms of HbA1c check-up servicing and the results of HbA1c prediction can also be used as a recommendation by doctor in determining the medical decision for diabetics.

Abstract

The use of electricity in household sector has increased, especially during the Covid-19 pandemic. The large number of activities carried out in home such as Work from Home, online schools, and online businesses caused difficulty to monitor the electricity consumption. The absence of electricity usage provisions affects the electricity monitoring process. Hence it takes a real time monitoring application of electricity consumption. Fuzzy subtractive clustering is an unsupervised method to form the number and center of clusters according to data conditions. This method serves to classify the household electricity users with the parameters used, is the amount of usage in rupiah and electric power. The grouping results from this method help users to monitoring electricity consumption in real time. The output describes the level of high, medium and low user electricity consumption. Based on the test results, the best Silhouette Coefficient value is 0.8322535 and three clusters are formed, with an accept ratio is 0.5, a reject ratio of 0.15, a radius of 1.7 and a squash factor of 0.5 hence a high level of use is obtained with an average value of the number of uses in IDR 655,993, power 2757 VA, medium level 240,553, 1071 VA and low level 46,479, 675 VA

Abstract

The process of analyzing and classifying comment data done by reading and sorting one by one negative comments and classifying them one by one using Ms. Excel not effective if the data to be processed in large quantities. Therefore, this study aims to apply sentiment analysis on comment data using K-Nearest Neighbor (KNN) method. The comment data used is the comments of the participants of the training on Udiklat Jakarta filled by each participant who followed the training. Furthermore, the comment data is processed by pre-processing, weighting the word using Term Frequency-Invers Document Frequency, calculating the similarity level between the training data and test data with cosine similarity. The process of applying sentiment analysis is done to determine whether the comment is positive or negative. Furthermore, these comments will be classified into four categories, namely: instructors, materials, facilities and infrastructure. The results of this study resulted in a system that can classify comment data automatically with an accuracy of 94.23%

Abstract

The determination of employee uses an alternative method to produce a decision. Methods for generating decision alternatives for employees who are entitled to travel is the method of Weighted Product. Weighted Methods Product has a consistent pattern in its calculation formula so that the calculation formula kesederhanan remains stubbornly high accuracy to four decimal places. determination of weighting between the criteria of benefit and cost criteria are within the powers of formula distinguishing numbers with positive and negative values ​​so the calculation becomes easier. Simplicity in calculation and the value of high accuracy is needed because the predefined criteria of ten criteria so that the result is very selective. This research was placed as a tool which is used prior to decision-making, for the alternative decision in determining employees in following official travel based on the criteria. This application required for the emergence of budget problems are less, the use of the budget surplus of the budget is predetermined. With this application, is expected to assist in the administration of official travel and provide the first step in saving and adjusting travel budgets in each of its parts.

Abstract

Automation in daily life has now become a necessity which began to be used in all areas, especially in the fields of education, economics, business, and industry. In the field of education , especially in elementary school, junior high school and high school, almost all the schools in Indonesia do electronic equipment settings which should help school personnel work with ease but still in do with the complicated, for example, conventional job still turn on and off the buzzer and lights, open the gates still use human tools, turn on a fan that has not been controlled in the center and many problems are still to be done manually with the help of human hand. In this case there needs to be a system that can manage and monitor the places they live and conduct electricity in a sustainable management. Responding to the issue in this thesis was designed and fabricated an integrated device such as intelligent building control system based on Android that uses a microcontroller, network and webserver in control. By utilizing the wireless connection technology , Raspberry, Arduino is expected to work optimally so as to provide safety and comfort .
