Abstract

Abstrak Banyak gejala yang akan dirasakan oleh manusia jika mengalami penyakit, dari gejala-gejala yang ada bisa dimiliki penyakit yang sama. Untuk memastikan kebenaran sebuah kesimpulan yang rumit dimiliki banyak penyakit tetap harus menggunakan pengetahuan dari dokter untuk pengambilan keputusan. Namun, tidak semua orang memiliki waktu dan kesempatan untuk menjumpai dokter. Hal ini dapat diatasi dengan kemajuan teknologi sekarang, dengan bermodalkan ponsel pintar, semua orang dapat mengakses apapun dan dimanapun. Dari permasalahan yang ada, kami memberikan solusi yaitu menyediakan aplikasi yang dapat mendeteksi penyakit berdasarkan gejala yang diberi nama “SiHelti”. Aplikasi ini dapat diakses menggunakan android. Model pengembangan aplikasi untuk aplikasi ini menggunakan metode Waterfall yang dimulai dari tahapan perancangan, implementasi, pengujian, dan deployment. Hasil dari pembuatan aplikasi ini diuji dalam pengujian acceptance testing dari pengguna untuk mengecek kelayakan dari aplikasi yang dibuat. Aplikasi diharapkan dapat membantu dalam mencegah masalah keterlambatan pengecekan penyakit pada masyarakat. Kata kunci : penyakit, aplikasi, android, waterfall, acceptance Abstract Many symptoms will be felt by humans if they experience a disease, from the symptoms that there can be the same disease. To ensure the correctness of a complex conclusion many diseases have to use the knowledge of doctors for decision making. However, not everyone has the time and opportunity to see a doctor. This can be overcome with advances in technology now, with smart phones, everyone can access anything, anywhere. From the existing problems, we provide a solution, namely providing an application that can detect diseases based on symptoms, which is named "SiHelti". This application can be accessed using android. The application development model for this application uses the Waterfall method which starts from the design, implementation, testing, and deployment stages. The results of making this application are tested in acceptance testing from the user to check the appropriateness of the application made. The application is expected to help prevent the problem of delays in checking disease in the community. Keywords: disease, application, android, waterfall, acceptance

Abstract

Pengguna internet di Indonesia pada tahun 2020 tercatat mengalami peningkatan sebanyak 17% dari tahun sebelumnya. Peningkatan tersebut membuka peluang baru di bidang perdagangan barang dan jasa di Indonesia. Penyediaan Akomodasi dan Makan Minum (Kategori I) memiliki peringkat kedua terbanyak dengan jumlah 4.431.154 usaha atau sekitar 17% dari total UMK di Indonesia. Data tersebut menunjukkan bahwa banyaknya UMK di bidang Penyedia makan minum yang bisa dimaksimalkan potensinya untuk mendongkrak perekonomian Indonesia. Permasalahan pemesanan katering juga ditemukan pada sejumlah mahasiswa Telkom. Mereka melakukan survei langsung ke toko fisik pada saat akan memesan katering sehingga 28 dari 30 orang (93%) merasa jasa katering perlu dibuat dalam bentuk platform digital. Survey lanjutan terhadap 10 orang responden juga menunjukkan bahwa 8 orang diantara 10 orang membeli katering dengan cara mendatangi toko fisiknya. Berdasarkan permasalahan dan fenomena tersebut, kami memiliki sebuah solusi yaitu Ketringan, sebuah marketplace katering yang memungkinkan orang bertransaksi dan mencari menu yang sesuai secara instan. Ketringan memiliki Unique Value Proposition (UVP) yaitu standarisasi, sistem pembayaran yang aman, dan harga yang sangat terjangkau. Kata kunci : Marketplace, Katering, UMK, Online, Aplikasi.

Abstract

Cryptocurrency price prediction is a crucial task for financial investors as it helps determine appropriate investment strategies and mitigate risk. In recent years, deep learning methods have shown promise in predicting time-series data, making them a viable approach for cryptocurrency price prediction. In this study, we compare the effectiveness of two deep learning techniques, the Recurrent Neural Network (RNN) and Long-Short Term Memory (LSTM), in predicting the prices of Bitcoin and Ethereum. Results of this research show that the LSTM method outperformed the RNN method, obtaining lower Root Mean Squared Error (RMSE) and Mean Absolute Percentage Error (MAPE) values for predicting both cryptocurrencies. Bitcoin and Ethereum. Specifically, the LSTM model had a RMSE of 0.061 and MAPE of 5.66% for predicting Bitcoin, and a RMSE of 0.036 and MAPE of 4.58% for predicting Ethereum. In this research, we found that the LSTM model is a more effective method for predicting cryptocurrency prices than the RNN model.

Abstract

Sentiment classification of user reviews plays a vital role in business decision-making, especially on e-commerce platforms like Tokopedia. This study evaluates the performance of various sentiment classification models such as Logistic Regression LinearSVC, and BERT models, both baseline and fine-tuned. Evaluation metrics used include accuracy, precision, recall, and F1-score, applied to Tokopedia review data labelled based on user ratings. The result is fine-tuned BERT model has the best and consistent result, with 92% accuracy and 0.92 f1-score for each class. This shows that fine-tuned BERT can effectively capture the semantic context of user reviews. Its consistent performance across classes makes it suitable for reliable sentiment classification in real-world applications. Furthermore, fine-tune BERT model is visualized by Local Interpretable Model-agnostic Explanation to identify features – in this case is word – that indicates sentiment as positive or negative. It will show as color, orange for positive and blue as negative. This method will make the model more transparent and more reliable.
