Abstract

Respiration rate is an important physiological parameter that helps to provide important information about the patient's health status, especially from the human respiratory system. So it is necessary to measure the human respiratory rate by calculating the number of respiratory frequencies within 1 minute. The respiratory rate meter is a tool used to calculate the respiratory rate by counting the number of breaths for 1 minute. The author makes a tool to detect human respiratory rate by using a sensor that detects the ascend and descend of the chest cavity based on a microcontroller so that the operator can measure the breathing rate more practically and accurately. Component tool contains analog signal conditioning circuit and microcontroller circuit accompanied by display in the form of LCD TFT. The results of measurement data on 10 respondents obtained an average error value, namely the position of the right chest cavity 6.6%, middle chest cavity 7.92%, and left chest cavity 6.85%. This value is still below the error tolerance limit of 10%. It can be concluded that to obtain the best measurement results, the sensor is placed in the position of the right chest cavity.

Abstract

Light Curing merupakan alat kedokteran gigi yang menghasilkan cahaya tampak dengan panjang gelombang 400-500 nm. Light Curing sendiri digunakan untuk mengeraskan bahan tambal gigi. Penambalan pada gigi tersebut dilakukan karena terjadinya kerusakan pada struktur gigi (Karies). Salah satu bahan tambal gigi untuk mengganti struktur gigi yang hilang yang digunakan saat ini adalah resin komposit. Alat ini akan menyinari resin komposit dengan waktu yang telah ditentukan, Penulis menggunakan Arduino NANO sebagai pengatur waktu pada alat. Proses penyinaram pada alat ini dilengkapi dengan 3 Mode Penyinaran (Stepped, Ramped, Dan Pulse-Delayed) dan juga pengaturan intensitas cahaya untuk mode konvensional. Berdasarkan hasil pengujian dan pengambilan data dengan mengukur kekerasan resin komposit dengan alat Hardness Tester, resin komposit yang di berikan penyinaran dengan waktu 20 detik, 40 detik dan 60 detik dengan ketebalan resin komposit 2mm. Pada alat dengan tambahan 3 mode dan tambahan pemilihan intensitas penyinaran dengan waktu 20 detik belum dapat memenuhi, namun pada penyinaran dengan waktu 40, dan 60 detik sudah dapat memenuhi tingkat kekuatan kunyah manusia yang mampu menahan sebesar 47 Ba. Pada hasil penyinaran 20 detik belum dapat memenuhi, hal ini dapat dipengaruhi oleh beberapa faktor diantaranya spesifikasi LED yang digunakan berbeda, kondisi lingkungan saat pemberian penyinaran pada resin komposit, kurangnya ketelitian saat menyiapkan sample yaitu kurang ratanya permukaan sample, dan ketelitian pembacaan saat pengujian.

Abstract

Berdasarkan data yang dikeluarkan oleh Organisasi Kesehatan Dunia (WHO) pada April 2011, kematian yang disebabkan oleh penyakit jantung koroner yang tidak menular telah mencapai 37% dari total jumlah kematian di Indonesia. Selain itu, dalam laporan WHO lain menyatakan bahwa pada tahun 2020, diperkirakan bahwa penyakit jantung koroner akan menjadi penyakit pembunuh utama di negara-negara di seluruh Asia-Pasifik. Tujuan dari penelitian adalah merancang deteksi sinyal jantung menggunakan stetoskop elektronik dengan sensor mic condensor untuk membandingkan nilai S1 (suara lub), S2 (suara dub), suara S3 yang disebabkan oleh osilasi darah antara dinding aorta dan ventrikular serta S4 yang disebabkan oleh turbulensi injeksi darah. Rancang bangun utama terdiri dari rangkaian pre-amp, filter jantung, mikrokontroller atmega 328p yang ditampilkan pada pc menggunakan delphi. Responden terdiri dari 5 laki-laki dan 5 perempuan, rentan usia berkisar antara 20 hingga 25 tahun, sedangkan untuk berat badan responden antara 50 hingga 76 Kg. Posisi perekaman suara jantung yang digunakan berbeda-beda untuk setiap respondennya, pada responden laki-laki didapatkan nilai amplitudo S1 dan S2 maksimal pada posisi perekaman Right Ventricel (RM), sedangkan untuk responden perempuan nilai amplitudo S1 dan S2 maksimal pada posisi perekaman Aortic (AO) dan Pulmonary Artery (PM). Untuk responden laki-laki maupun perempuan Ada banyak faktor yang mempengaruhi amplitudo S1 dan S2 setiap pasien sedangkan untuk nilai S3 dan S4 tidak terlihat dengan jelas. Jika berat badan responden diatas berat badan idealnya maka amplitudo S1 dan S2 akan cenderung lebih kecil dan sebaliknya, jika berat badan responden kurang dari berat badan idealnya maka amplitudo S1 dan S2 akan cenderung lebih besar. Selain itu juga, seberapa kuat stetoskop ditekan ketika melakukan perekaman juga dapat mempengaruhi amplitudo S1 dan S2. Terdapat kendala pada proses pengambilan data dimana responden perempuan cenderung lebih sulit untuk menemukan titik rekaman suara jantung di bandingkan laki-laki dan hanya pada titl-titik sadapan tertentu yang dapat terlihat nilai S1 dan S2 dengan jelas. Hal tersebut dapat diakibatkan oleh frekuensi cut off yang lebar, berkisar antara 10 – 1000Hz sehingga terdapat noise terutama suara paru-paru.
