Abstract

In a large dataset, data mining is a solution to arrange new models into useful information. The algorithm is often used in machine learning is C4.5. This algorithm is known to be very strong in classifying, but has several weaknesses, such as overlapping and overfitting of data. To handle this, it is necessary to select an attribute that can identify the relevant attribute without reducing the accuracy of the algorithm itself. The Particle Swarm Optimization (PSO) is an optimization algorithm which one can be used as an attribute selection. The PSO benefit is that to easy to use, efficient and has a simple concept when to compared of data mining algorithms and other optimization techniques. In this study, the precision of C4.5 which is optimized by Particle Swarm Optimization (PSO) algorithm is proven to be higher than using the C4.5 algorithm alone. Where the algorithm C4.5+PSO has an precision of 66.80% while the algorithm of C4.5 has an precision of 76.32%.

Abstract

Water is one of the most important sources of life. One way to save water is by monitoring the flow of water consumed per month. The flow rate measurement is applied to every household that uses the PDAM, so that each house is installed a water meter, which is used to measure or record the volume of water that has been used for each household’s needs. The measurement of the volume of water contained in the water meter is used to determine the number of tariffs that must be paid by each household to the PDAM every month of use. In this research, a system is made that can monitor the quality and use of PDAM water. In this system, a turbidity sensor is used which will measure the level of water turbidity in NTU units. This NTU value will show the quality of PDAM water whether it is suitable for use in daily needs or not. The water flow sensor will be installed in the middle of the PDAM pipe, the water flow data measured on the sensor will be processed on the Arduino Uno module to be converted into data for the estimated cost of using PDAM water. Furthermore, all data will be displayed on the LCD, namely data on the level of water turbidity, data on the amount of water discharge and the estimated cost to be paid by the customer. All data will be sent to the blynk server via ESP32 Camera. The data stored on the server can be accessed using the blynk application on a smartphone. In addition, the data will also be stored on the SD Card as a data backup. The results of the turbidity sensor readings show a water turbidity value of 5 NTU. The error value of the water flow sensor readings is 1.6%, which means the accuracy rate is 98.4%. While the data from the reading of the PDAM water usage costing system has no errors so that the data accuracy reaches 100%.

Abstract

Traffic accident is one of the most significant contributors which makes the death number is increasing around the world. With the demographic condition from Indonesia, motorcycle driver is the types of the driver that dominated the traffic, therefore increasing the probability of caught in a traffic accident The existing Vehicle Activity Detection System (VADS) mainly focused on the car driver, with the main problem is that the computational time from the system is too high to be implemented on a real-time condition. To solve this problem, in this research, a classification system for abnormal driving behavior from motorcycle drivers is created, using Light Gradient Boosting Machine (LightGBM) model. The system is designed to be lightweight in computation and very fast in response to the changes of the activities with a high velocity. To train the LightGBM model, the data from Accelerometer and Gyroscope sensor, that has been integrated into a smartphone, will be used to detect the movement from a driver. The accuracy rate from the proposed model is reaching 82% on the test dataset and shows a promising result of around 70% on the real-time detection process. With a computational time of around 10ms, the proposed system is able to work 5 times faster than the existing system.

Abstract

Waste products are increasing every day in line with the increasing number of products and people's consumption patterns. Many people do not separate organic and inorganic waste during disposal. One of the reasons is that people cannot distinguish between organic and inorganic waste. Based on these problems, an Internet of Things-based tool was designed that uses NodeMCU ESP8266 as its microcontroller. To distinguish organic and inorganic waste, three sensors are used at once, namely proximity infrared, capacitive and inductive sensors. The data read by this tool then turns on the LED according to the type of trash can. In this study, a trash can was also designed that uses an ultrasonic sensor to detect the height of the garbage. This altitude information is then sent to a website-based monitoring application using a Wi-Fi network and the MQTT protocol. This application is used by cleaners to monitor which trash bins have to be transported. From the test results, the three proximity sensors used succeeded in distinguishing organic and inorganic waste. The recommended distance for the sensor to work optimally is 3 mm. The data obtained by the sorting tool has also been successfully sent to the waste height monitoring application. Officers get notifications on the website, which trash bins must be transported.

Abstract

Water is one of the keys to the success of rice farming. Rice fields that are always flooded can produce 5.92 tons per hectare while those that are not flooded only produce 4.80 tons per hectare. Irrigation channels that support the availability of water often experience problems such as silt deposits, water distribution based on estimates, and water theft. Therefore, the author proposes an intelligent irrigation system that is able to automate the control and supervision of floodgates through the internet network. The result of this research is a prototype system that can work well, with an average measurement error of 2.1% by ultrasonic sensors, and the conductivity of water flow with silt is above 641 points. Radio-based communications and TCP/IP require lower operational costs than SMS-based GSM methods. Radio-based technology and TCP/IP can save operating costs by 97.5% compared to GSM technology. The system is also capable of sending 16 data to the server in one minute. Overall, the system has worked well to automate the floodgates, and detect sludge.

Abstract

Existing research on course scheduling was conducted only from the institutional side.  However, students usually have other considerations, such as routine activities outside of class, course time, holidays in a week of study, and lead time between courses. These conditions had never been taken into consideration in existing research.  In this paper, a recommendation system was proposed using Depth First Search and Simple Multi Attribute Ranking Technique methods.  Depth First Search method was used to find all possible alternative schedules. All the possible alternative schedules were used to determine the schedule that best suits student preferences using Simple Multi Attribute Ranking Technique method. The system performance was measured through simulation to get course schedule recommendations for 28 students.  The simulation results were compared with the ideal schedule desired by the students and the real course schedule for those students. The accuracy of the recommended schedule against the ideal schedule desired by students was 70.8% with an average processing time of 1.05 seconds. The accuracy of the recommended schedule increased to about 91% when compared to the actual student courses schedule.  So it can be concluded that the research can help to recommend students' weekly class schedules in real terms.
