Abstract

Signal quality assessment is important procedure to assess if a signal can be preprocessed into next step or not. In this study, we proposed an improving of convolutional neural network with recurrent model and generative adversarial network. The experiment shows that enhancing convolutional neural network by using recurrent model or data augmentation via GAN for wearable ECG signal quality assessment is feasible to try. Adding recurrent model to CNN increase its performance by approximately 3% margin in un-augmented dataset. Generating fake samples from “unacceptable” class can enhance CNN performance up to 2% margin. Combination of recurrent model and GAN still not yet matched found. However, It doesn’t mean that the combination is impossible to do.

Abstract

Keys play an important role in a security system. Most room door security systems still use conventional door locks, especially in room management applications. Room management with conventional keys has several problems, such as long key searches for each loan, and easily lost and duplicated. Therefore, the authors propose a door lock system that is capable of automating room door control and supervision via the internet network. Research that has been done previously uses single factor authentication (SFA). This technology is less secure for the authentication process for parties/users who want to access the room. This research proposes that a system with multi factor authentication (MFA) aims to protect the system from unauthorized users. The MFA concept will be implemented by validating the physical token on the RFID card and the security code or PIN entered by the user. MFA also increases the level of security and allows the implementation of identification, verification and authentication to ensure user authority. The results of this study are system prototypes that can work well, the system can be realized using backend services using expressjs and data stored in cloud services that can be accessed anytime and from anywhere by the client. The system can also be realized using a combination of nodejs, expressjs, PostgreSQL and esp32 client technologies. The validation process at check-in can occur within 207ms. The server is reliable enough to execute 500 requests simultaneously. Overall, the system has worked well for room management.

Abstract

People's living standards are increasing with the development of the global economy, so that the production of domestic waste is increasing from year to year. However, in waste processing there is still a problem of mixing waste in landfills where hazardous waste is still mixed so that it can cause the spread of covid. Currently the trend is starting to shift to smart devices that use the Internet of Things to solve common problems such as waste management problems. In this study, a Mobile Smart Trashbin is proposed which can reduce direct interaction because it has an automatic opening and closing feature, can sort waste into hazardous and harmless, can transmit waste weight data, and can be controlled remotely and equipped with livestream. The developed system is tested by the methods of functionality testing, performance testing, and connectivity testing. Functionality testing gives the result that the whole system can work. Performance testing on the ultrasonic sensor results in an accuracy rate of 97.18%, the MG995 servo motor is at 100%, the weight sensor has an accuracy rate of 98.65%, and the use of batteries in standby can work for 13 hours 3 minutes 40 seconds and in a running state can work for 1 hour 56 minutes 42 seconds. The connectivity test of the average delay of robot control when given a command is 103.4ms, and the delay in sending waste weight data is 112.8ms.

Abstract

Feed is a vital element crucial to supporting the growth and survival of livestock. Forages, commonly known as livestock fodder, serve as the primary food source for animals and form the foundation of livestock development efforts. Sei Mencirim Village has a livestock farmers' group named "Mencirim Ayu." This group comprises 15 farmers, each raising an average of 10 head of livestock, specifically goats/sheep. The issue faced by the group is the direct feeding of animals due to the lack of a feed chopper. The proposed solution involves creating and providing a livestock feed chopper machine and training on its usage. The outcome of this Community Partnership Program (PKM) activity includes implementing a chopper machine with a capacity of 30-50 kg/hour. Farmers can produce feed more economically for their livestock with this machine, potentially enhancing productivity.

Abstract

Community Service aims to increase the income of farmer groups by making hydroponics based IoT, the Mekar Ayu Farmers Group in Sei Mencirim Village has so far relied on horticultural farming by using agricultural land that is very dependent on nature and controlling hama by spraying anti-pests which results in the harvest being contaminated with these anti-pest substances. Farming groups have not utilized the empty land around the group members' housing which can be used to create various businesses that can increase their members' income, such as training in hydroponics, sowing water spinach and bok choi seeds. The problem is that there is no hydroponics yet, even though the land for laying hydroponics is mostly in the homes of members of farmer groups. So far, farmer groups have relied on agricultural land and knowledge of sowing seeds. IoT-based hydroponic production training solutions and seeding and pest control training until harvest arrives.
