Abstract

The service system for every laundry in every area is currently still done manually, this is considered less efficient because the waiters are often confused when looking for clothes that a customer wants to pick up. Then waiters sometimes forget to give information to customers to pick up clothes that have been washed. This becomes a problem where customers have to go back and forth to ask whether their clothes have been washed or not. Smart laundry is a form of implementation whose main objective is to help customers find out which clothes are ready to be picked up and can help waiters find out where the customer's clothes are. RFID tags for customers who are registered as members of the laundry service are used as a tool to store customer data when the customer brings clothes to be washed and to find out where the customer's clothes have been washed when the customer picks up the clothes. This research also uses the QoS (Quality of Service) method to measure the delay parameters produced in the network used. The results of testing that were carried out 35 times in this research resulted in a delay of 0.956458 seconds. From the test results, the maximum reading distance between the RFID tag and the RFID reader is 3 cm. From the results of 10 trials, the percentage of system success in sending notifications in the form of clothes that have been completed and ready to be picked up to customers is 80% and system failure in sending notifications is 20%.

Abstract

One of the problems that internet users often face is slow internet access. This problem can occur because there is no bandwidth management system in use. The Random Early Detection and Hierarchical Token Bucket methods are good methods. However, it is not yet known which is the best between the two. Research needs to be carried out to determine the comparison of network quality using these two methods. This research aims to determine the quality of networks that apply the Random Early Detection and Hierarchical Token Bucket methods whether they are given noise injection or not. This research data was collected by testing the wireless local area network. The collected data is analyzed using QoS. The results show that the implementation of the Hierarchical Token Bucket method is of better quality, it can be seen with a throughtput value of 879128 bps, a delay value of 8 ms, a jitter value of 11,041 ms and a packet loss value of 0%. On the other hand, the Hierarchical Token Bucket method was given Noise Injection with a throughput of 582716 bps, a delay value of 15,427 ms, a jitter value of 21,924 ms and a packet loss value of 2.8%. Meanwhile, the application of the Random Early Detection method obtains quality with a throughput value of 816,287 bps, a delay value of 8,673 ms, a jitter value of 12,591 ms and a packet loss value of 0%. On the other hand, the Random Early Detection method is given Noise Injection with a throughput value of 704778 bps, a delay value of 11,154 ms, a jitter value of 15,565 ms and a packet loss value of 2.14%.

Abstract

The system of pressing the electricity token value button on the prepaid electricity kWh meter is a tool that works by filling in the electricity token value via smartphone with the MIT APP Inventor server which aims to make it easier for prepaid electricity users by not having direct contact with the prepaid kWh meter. In general, filling in the value of electricity tokens is still done manually and what happens is that there are still many people who experience problems with distance and are afraid to top up the value of electricity tokens manually. This research aims to create a control system for pressing keypad buttons on prepaid kWh meters. The control system uses Arduino Uno with the MIT APP Inventor server as input from the smartphone. Data sent from the smartphone will be received by the Bluetooth Module which is processed by the Arduino Uno as a microcontroller to control the relay driver as a selonoid controller, the selonoid as a button press will work by inputting the electrical token value that has been input. The research results show that a system of pressing the electricity token value button on the prepaid electricity kWh meter has been realized. Testing is carried out by operating and testing the tool functionally and the performance of all components as well as realizing that the tool is successful and the tool works as expected.

Abstract

Cloud storage is a technology used to store data online. However, this technology also poses problems in terms of security. Therefore, the author wants to build a cloud storage system by implementing cryptographic security to secure data. By implementing cryptographic techniques in cloud storage, users don't need to worry about data loss or theft. The cryptographic method applied is the Vigenere Cipher algorithm, which is a classic type of cryptography. Cloud storage is applied to public and private networks to test the comparison of data encryption times. Based on tests carried out, implementation on private networks is better with an average time of 3.84 seconds for encryption and 253.6 milliseconds for decryption. Meanwhile, on public networks, the average time is 45.3 seconds for encryption and 392 milliseconds for decryption. To measure whether cryptography is effective or not, the avalanche affect method is used which produces a value of 1.4% to 7% with an average of 3.92%.

Abstract

The problem and obstacle currently experienced by aquarium users is that users have to check the condition of the food and water conditions by coming directly to the aquarium. This method can be annoying and waste a lot of the user's time working and it is certainly not easy if every time the user has to directly check the condition of the feed and water in the aquarium. So from this problem I designed a system, namely designing an aquarium prototype based on IoT (internet of things) which can help with the problems being faced by aquarium users. This system is a sophisticated manual system using Arduino Wemos D1, Turbidity sensors and Proximity sensors to determine the condition of fish food and water conditions in the aquarium. With this system, it can make it easier for users to know the condition of the feed and water conditions in the aquarium, so that the user's time is not wasted and the user does not need to bother taking care of the condition of the aquarium. From the results of water testing using the Turbidity sensor, the values ​​for very turbid water conditions were 266, 272, 281, 283, turbid water 518, 526, 536, 544 and clear water 589, 590, 594, 595. In the Proximity sensor test, the has a value of 1 when the sensor detects the presence of food and the sensor has a value of 0 when it does not detect the presence of food.

Abstract

The flow of news regarding the development of Covid-19 has dominated various information channels in Indonesia in the last 2 years, either through print media or digital media. Various types of news related to Covid-19 continue to circulate, including hoax news. One of the hoax news that is widely circulating is news about the Covid-19 vaccine. The rise of information containing hoax news and untrue rumors about the Covid-19 vaccine in society can worsen the pandemic situation. Currently there is no intelligent system capable of classifying hoaxes regarding the Covid-19 vaccine. To maximize prevention of the spread of hoax news about the Covid-19 vaccine and overcome the problems faced, the author designed a classification system for hoax news about the Covid-19 vaccine using a machine learning approach. The system built can classify news using a combination of the Name Entity Recognition (NER) and Backpropagation algorithms. The datasets used are: 600 Covid-19 vaccine news data obtained from the sites https://turnbackhoax.id/ and https://www.kompas.com/ with the keyword "covid vaccine". The dataset is divided into two, training data and test data. The training data is preprocessed and then used in model design. Test data is used to evaluate the results of model design. This process produces a machine learning model with a good accuracy level of 97.62%.

Abstract

Traffic accidents are a significant problem in various areas, including highways that cross National Park areas. This research aims to analyze the level of traffic accidents on roads in Baluran National Park using the Equivalent Accident Number (EAN) method as an evaluation tool. This case study involves collecting data on traffic accidents, traffic characteristics, and related environmental factors. The first step involves collecting traffic accident data from relevant agencies, including accident locations, types of accidents, and victims involved. Risk factors such as speed, traffic volume and road conditions are also identified to support the analysis. The AEK method is then applied to calculate the expected equivalent number of accidents based on traffic characteristics and road parameters. The analysis results show the actual accident rate compared to the calculated AEK. If the AEK is higher, this indicates that the location has a significant risk of accidents. Recommendations for improvement were then put forward, including improving infrastructure, implementing more effective traffic signs, and efforts to increase driver awareness. This research makes an important contribution to understanding and overcoming the challenges of traffic accidents in Baluran National Park. With the AEK approach, policies can be designed to effectively improve traffic safety, while maintaining the environmental sustainability of the National Park.

Abstract

A parking area is a place where consumers or the public can park their cars or vehicles in the empty spaces provided in the parking lot. Usually the parking area is filled with quite a lot of vehicles, so it is difficult to find empty parking spaces that are still available in the parking area, due to the density of cars or vehicles passing around the parking area who also want to find empty spaces that are still available to park their cars. This thesis aims to create a parking system that can be monitored via smartphone to determine the availability of parking slots. The parking system uses a raspberry pi microcontroller, an infrared sensor which functions to detect cars entering each parking space, LEDs are used as indicator lights to notify the status of each parking space. The results obtained from system testing are that the system has been successfully implemented as expected based on respondents' responses to the feasibility of an IoT-based intelligent parking system application using questionnaire data from 40 respondents indicating "Strongly Disagree = 0%", "Disagree = 0.5%" , “Neutral = 20.5%”, “Agree = 93.5%”, “Strongly Agree = 88%”. The maximum distance for infrared sensor detection is 80 cm. Meanwhile, the speed of obtaining data values ​​from the sensor also depends on the distance and voltage applied to the sensor.
