Abstract

The process of education and learning in public schools has limitations on communication problems for the deaf. The communication process in public schools is based on verbal language, whereas the deaf rely on sign language to communicate. Based on this problem, an auxiliary communication tool is needed to carry out learning with deaf students. The systems used in the e-learning process can support the learning process of deaf students. The main feature in this learning process is converting voice into sign language in real-time. Two-way communication requires video, audio, and chat. The system is set up using Web Realtime Communication (WebRTC) as a real-time data transfer protocol using a browser.

Abstract

PT. Digital Indonesia Berkat or what is called Tokocrypto is a cryptocurrency exchange company based in Jakarta that is officially registered with the Commodity Futures Trading Regulatory Agency (Bappebti). The level of customer satisfaction is of course very important to note so that companies can benefit and retain service users to continue using the company's services and attract potential service users. Public sentiment towards a cryptocurrency can also affect the price of the cryptocurrency such as the cryptocurrency owned by Tokocrypto called TKO. The amount of data provided by customers will take a long time to be analyzed manually. To overcome this, sentiment analysis can be carried out using a machine learning model that can understand the content of Tokocrypto customer feedback. This study applies the Bidirectional LSTM method to classify sentiment analysis using the tweet data of Tokocrypto service users. In addition, it is necessary to apply pre-processing of text data to overcome customer feedback which includes non-standard words and slang which causes the model to not understand the original meaning. The model is also adjusted for hyperparameters with the grid search method so that the model gets the optimal combination of parameters. Changing non-standard words does not guarantee increasing the accuracy of the model but can still help produce a better model with evaluation results including an f1-score value of 0.9485, a precision value of 0.9423, a recall value of 0.92, a training loss value of 0.0001 and a validation loss value of 0.0004.

Abstract

Hydroponics is one of today's modern farming methods that can be done on limited land. Hydroponics is a farming method without using soil as a medium but using water. One of the main factors for the success of hydroponic farming is controlling the conditions of the growing media, in which the growing medium is water. Temperature and pH are parameters that can be controlled to ensure successful farming with the hydroponic method. Currently, the way to control the temperature and pH values of water is usually done by manual monitoring every day. This method is considered very impractical. Therefore, innovation is needed in the field of technology that can monitor and automate the pH value and water temperature. In this research, a prototype system was created that can perform this function using the Internet of Things method assisted by an Android application as output. This system uses ESP8266 as the main processor to measure temperature and pH values and automate pH values using a 12-volt DC pump and 5-volt submersible pump as well as automate temperature values using a DC fan in the hydroponic system. The accuracy of reading the temperature and pH values obtained by the system is quite high, namely 96.58% for the pH sensor and 99.61% for the temperature sensor. The android application that was created can run well and the system prototype was also successful in automating the hydroponic system's pH and water values.
