Abstract

Penyakit jantung merupakan salah satu penyebab utama kematian di dunia dan masih menjadi penyebab kematian tertinggi di Indonesia. Kondisi geografis Indonesia yang terdiri dari 7000 pulau menyebabkan proses penanganan penyakit jantung lebih sulit, terutama pada daerah terpencil. Proses deteksi dini penyakit jantung perlu dilakukan sebagai upaya mengurangi angka kematian. Namun proses deteksi dini dari penyakit jantung menjadi tantangan yang sulit, karena membutuhkan biaya yang mahal dan bergantung dengan petugas medis untuk hasil deteksi yang akurat. Seiring berkembangnya teknologi, smartphone mulai bermunculan dengan kemampuan yang semakin canggih dan dapat mendukung perkembangan aplikasi mobile health sebagai solusi untuk pemantauan kesehatan jarak jauh. Dalam Tugas Akhir ini, dirancang stetoskop yang terhubung dengan smartphone berbasis android untuk proses analisa sinyal suara jantung menggunakan aplikasi. Aplikasi akan dilengkapi metode identifikasi suara sehingga dapat mengurangi ketergantungan pengguna dengan petugas medis. Sinyal suara jantung akan diproses menggunakan metode Discrete Wavelet Transform untuk denoising dan metode Linear Envelope untuk pemrosesan suara jantung. Alat dirancang dengan menggunakan stetoskop berbiaya rendah yang membedakan dengan stetoskop elektronik di pasaran. Dari proses identifikasi sinyal suara jantung yang dilakukan dengan 20 subjek, 75% dari data perekaman sinyal jantung menghasilkan keluaran identifikasi yang akurat. Data sinyal PCG, pemrosesan, dan hasil ditampilkan pada aplikasi android secara optimal.

Heart disease is one of the leading causes of death worldwide and the highest cause of death in Indonesia. The geographic conditions of Indonesia, comprising over 7000 islands, engender significant challenges in managing heart disease, particularly in remote and underdeveloped areas. Early detection is critical for reducing mortality rates associated with heart disease. However, this process poses challenges due to its high cost and reliance on clinicians for accurate detection. With technological advancements, smartphones have emerged with increasingly advanced capabilities, supporting the development of mobile health applications for remote health monitoring. This research aims to create an electronic stethoscope that connects to an Android-based smartphone application for heart sound signal identification. The application offers a reliable validation method to reduce dependency on clinicians. The process of heart sound signal uses the 5^th levels of the Discrete Wavelet Transform method for denoising and the Linear Envelope method for heart sound identification. The instrument design incorporates a cost-effective stethoscope, distinguishing it from existing electronic stethoscopes in the market. The heart sound identification method was applied to 20 individuals, revealing that 75% of the recorded heart signal data generated precise identification results. The Android application effectively showcases PCG signal data, processing, and outcomes.
