Abstract

AbstrakParu-paru merupakan organ tubuh pada manusia dalam menjalankan sistem respirasi (pernapasan), dan berfungsi sebagai bertukarnya oksigen dan karbondioksida. Untuk mendeteksi suara paru-paru diperlukan stetoskop sebagai alat untuk mendengarkan suara pada paru-paru. Teknik ini disebut sebagai auskultasi, dimana pada teknik ini banyak batasan dan kekurangan. Untuk mengatasi permasalahan tersebut maka pada penelitian ini diusulkan sebuah teknik auskultasi yang dimodifikasi dengan electret condenser microphone untuk menangkap suara pada paru-paru. Tipe yang digunakan electret condenser microphone yaitu unidirectional (cardioid). Sinyal listrik yang dihasilkan oleh electret condenser microphone dikuatkan lagi menggunakan pre-amplifier karna sinyal listrik yang dihasilkan electrets condenser microphone sangat kecil. Pre-amplifier yang digunakan yaitu tube ultragain mic100. Sinyal yang dikuatkan dengan pre-amplifier masih berbentuk sinyal listrik, sinyal listrik ini akan diproses di DSP untuk mengubah sinyal menjadi data diskrit untuk mengubah sinyal suara ke sinyal listrik analog. Sinyal analog akan diubah melalui unit ADC agar dapat berubah menjadi sinyal digital kemudian DSP akan menerima sinyal digital dan memproses data digital tersebut yang kemudian sinyal disimpan dalam bentuk  file .wav. File .wav yang disimpan kemudian dipindahkan ke android melalui RobotDyn UNO+WIFI sebagai media komunikasi. RobotDyn UNO+WIFI yang digunakan yaitu tipe  ATmega328p+ESP8266 CH340G, file .Wav diproses dan diputar untuk dapat divisualisasikan pada android sehingga mempermudah dokter dalam menganalisa suara paru-paru pasien.  Kata kunci:  Suara paru-paru, Stetoskop, Electret Condenser Microphone, Pre-Amplifier dan DSP TMS320C6416T, dan RobotDyn UNO+WIFI ATmega328p+ESP8266 CH340G. AbstractThe lungs are organs in the human body in carrying out the respiratory system (breathing).  It function as the exchange of oxygen and carbon dioxide. To detect lung sounds, a stethoscope is needed as a tool to listen the sounds in the lungs. This technique is called auscultation.  In this technique, there are many limitations and disadvantages. Thus, to overcome this problem, this study proposed an auscultation technique modified with an electret condenser microphone to capture sounds in the lungs. The type used by the electret condenser microphone is unidirectional (cardioid). The electrical signal generated by the electret condenser microphone is amplified using a pre-amplifier because the electrical signal generated by the electrets condenser microphone is very small. The pre-amplifier used is the mic100 ultragain tube. The signal that is amplified by the pre-amplifier is still in the form of an electrical signal, this electrical signal will be processed on the DSP to convert the signal into discrete data to convert the sound signal to an analog electrical signal. The analog signal will be converted through the ADC unit so that it can be transformed into a digital signal then the DSP will receive a digital signal and process the digital data which is then stored in the form of a .wav file. The saved .wav file is then transferred to android via RobotDyn UNO + WIFI as a communication medium. RobotDyn UNO + WIFI used is the type ATmega328p + ESP8266 CH340G, .Wav files are processed and played so that it can be visualized on Android making it easier for doctors to analyze the sound of a patient's lungs. Keywords:  Lung sounds, Stethoscope, Electret Condenser Microphone, Pre-Amplifier and DSP TMS320C6416T, and RobotDyn UNO + WIFI ATmega328p + ESP8266 CH340G.

Abstract

SMPIT Harapan Mulia is one of the schools that uses iPad for its teaching and learning activities.  The use of this small, simple and lightweight iPad is certainly one of the solutions to reduce the burden of the books that the students should carry.  All the learning materials can be found easily in the iPad, therefore the students can learn many things anywhere and anytime. In addition, the use of this iPad also will certainly make the students to more focus on the lesson.  The students have an opportunity to be more flexible in terms of self-development.  Besides the benefits provided by the iPad, there are several obstacles that are often faced, including, the use of iPad is monotonous andexcessive use of iPad can reduce student performance compared to those who do not use tablets (according to research from the Organization for Economic Cooperation and Development (OECD) and University of Michigan). Based on observations and interviews with the principal at SMPIT Harapan Mulia, students who use the iPad are more enthusiastic in joining the teaching and learning process. This can be proven by an increase in the average value obtained by the students of SMPIT Mulia Harapan. However, unfortunately the school also often found the students looked bored with their tablets. This is because their iPad is connected directly to MDM (Mobile Device Management), where the MDM manages the content and activities on each student's iPad.  This MDM limits the student's movement, so that they will not get out of line. However, this MDM also makes students feel uncomfortable and not to be free to express themselves.  Therefore, we need a solution to overcome these problems. This dedication is carried out with the aim to maintain the stability of the students' enthusiasm in using the iPad. In practice, this service provides opportunities for students to develop their skills in using the iPad. Students are equipped with the theory of the development of the use of iPad (in this activity, the iPad is used to control the trash robot). Besides that, the service activity also demonstrated and gave a short workshop on the control of garbage robots using the iPad. The results of this dedication were a simple coding and a monitoring module using a Blynk based iPad.
