Abstract
Pola makan yang tidak sehat memicu berbagai penyakit seperti hipertensi, diabetes, obesitas, jantung, dan lainnya. Untuk mencegah resiko mengalami penyakit-penyakit tersebut, masyarakat harus membiasakan gaya hidup sehat, dan rajin melakukan olahraga. Salah satu jenis olahraga yang dapat dilakukan oleh seluruh lapisan masyarakat tanpa mengeluarkan biaya adalah berjalan kaki. DEPKES RI, serta para ahli, merekomendasikan olahraga jalan kaki sebanyak 1.000 langkah sebagai target minimal, dan 10.000 langkah tiap harinya sebagai target jangka panjang. Maka, diperlukan alat yang mampu menghitung langkah kaki dan jumlah kalori terbakar, serta menampilkan hasilnya di telepon genggam pengguna. Alat tersebut dibangun menggunakan sensor akselerometer, dimana data diolah dengan mikrokontroler Arduino Nano untuk selanjutnya dikirimkan ke telepon seluler pengguna untuk ditampilkan. Pengolahan data dilakukan dengan cara menghitung varians dari masing-masing sumbu sensor dan menjumlahkannya. Kemudian, mikrokontroler menghitung selisih dari penjumlahan tersebut dengan rata-ratanya. Hasil perhitungan selisih inilah yang kemudian menjadi penentu pemasangan threshold untuk menghitung jumlah langkah kaki. Dari 18 kali total pengujian, didapatkan rata-rata akurasi alat sebesar 91,48%.

The unhealthy diet then overcomes various diseases such as hypertension, diabetes, obesity, heart disease, and others. To avoid the risk of being overcome by the diseases, the community must familiarize a healthy lifestyle, such as making a healthy and regular diet with diligent exercise. One type of exercise that can be carried out by all levels of society without spending is walking exercise. Ministry of Health of Republic of Indonesia, as well as experts, recommends exercising as many as 1,000 steps to walk as a minimum target, and 10,000 steps everyday as a long-term target. So, a device is needed to be able to count the number of footsteps. The device is built by using an accelerometer sensor where the data is processed within Arduino Nano microcontroller to be sent to the user's mobile phone to be displayed. The data processing is done by calculating the variance from each accelerometer sensor's axis, and add them up. Then, the microcontroller calculates the diference of the sum from its average. The result of this calculation determines the threshold value to count footsteps. From the total of 18 tests, it was found the the average accuracy of the device was 91,48%.
