Abstract

In data mining, predictions are known to find knowledge about what will happen in the future. Predictions are usually made on time-series data. The Consumer Price Index (CPI) is an index value derived from daily consumer price data. The results of the CPI calculation are derived from observations of commodity prices at the household consumer level, which are carried out routinely on a daily, weekly, bi-weekly, and monthly basis. CPI prediction can be done using a data mining algorithm, namely Support Vector Regression (SVR). SVR is part of the Support Vector Machine algorithm that functions to solve regression cases. SVR is a reliable algorithm in the case of regression because it can handle data overfitting well. The data used as input in this paper comes from 34 food commodity prices, and the output data is obtained from the CPI value data. The food commodity price data used is from Surabaya City. The data period used is from 2014-2020. The results of the implementation of SVR with 4 kernels show that the Polynomial kernel has the best error rate with a MAPE value of 4.31%.

Perintah suara merupakan salah satu media pengoperasian sistem automation yang banyak diminati. Pengoperasian sistem yang mudah dan tidak membutuhkan banyak tenaga merupakan alasan utama perintah suara cocok digunakan untuk sistem automation. voice recognition dapat digambarkan sebagai suatu proses di mana mesin atau program menerima dan menafsirkan dikte serta memahami dan menjalankan perintah yang diucapkan. Penggunaaan suara adalah suatu cara berkomunikasi yang paling sering dilakukan oleh manusia. Dimana penelitian dibidang pengelolahan suara telah memotivasi banyak orang untuk menciptakan model mekanik untuk meniru kemampuan komunikasi verbal manusia. Tujuan penelitian ini yaitu untuk memperoleh informasi dari hasil spectrum perintah suara manusia, sehingga mampu di terapkan pada sistem automation seperti home automation, smart wheelchair dan peralatan automation lainnya yang mampu memahami bahasa manusia sehingga dapat menjalankan apa yang pengguna perintahkan. Dari hasil penelitian ini menghasilkan untuk kelompok pria dan wanita durasi waktu yang dibutuhkan rata-rata menunjukkan nilai berkisar antara 0,5344 – 0,8217 (pria) dan 0,9001 – 1,1135 seconds (perempuan), artinya bahwa pria lebih membutuhkan sedikit waktu dalam mengeluarkan perintah suara dibandingkan wanita. Nilai Kedekatan dengan standar perintah suara untuk Pria dan wanita hampir memiliki kesamaan yaitu 1,00 hingga 3,00 atau 97 % - 99 %. Artinya tidak terlalu adanya perbedaan yang cukup signifikan ketika pria dan wanita menghasilkan suara yang disesuaikan dengan pedoman perintah suara. Sehingga jika metode ini diterapkan untuk sistem Voice Recognition, metode ini dapat menangkap suara yang diberikan oleh pengguna dengan cukup akurat yaitu diatas 90% akurasi Kata kunci: deteksi suara, pengenalan suara, perintah suara, sistem deteksi suara, audacity
