Projects

Contact Tracing App

An app, generated from Streamlit library, can be used for tracing the historical contact location, it is usually done especially during the COVID-19 pandemic. Through the app the tracing process can be searched based on free text, zip code, business ID, and device ID.

Library App

App to simulate borrowing book and record all the borrowing and returning (active or not active) by which customer and book in database.

Sentiment Analysis - Tweets

The project aims to develop a ML model to classify sentiments on Twitter, about 2019 Indonesian Presidential Election. This system will help obtain positive, negative or neutral opinion sentiment trends from users on the platform. To achieve that, this project use Random Forest and LSTM models.

Text Summarization - Liputan6

Developed a model for summarizing documents using text understanding method which can obtain the main idea of a news from Liputan6 News dataset. Thus, users can get the text in a more concise. To achieve that, this project use BERT and T5 models.

Automatic Speech Recognition - Minds14

Utilize and fine-tune pre-trained Wav2Vec2, Whisper, and HuBERT models to convert speech to text. The project uses MINDS-14 dataset which popular in domain research. Specifically uses the English (US) language version dataset.
