Abstract

The purpose of this prototype is to enhance communication between stroke patients and their caregivers, as difficulty in understanding the nuanced wishes of stroke patients often leads to a reduced quality of life for the patients and increased caregiver depression. This study aimed to address these challenges by providing a more effective means of interpreting the desires of stroke patients during their interactions with their caregivers. The prototype utilizes a dual-input system to capture the intricate communication dynamics. The first input involves recording the finger movements of the patient through touch interaction with the TTP223 touch sensor area. In contrast, the second input comprises a time-step phrase that serves as a complementary mechanism for selecting communication phrases. The combination of these inputs is processed using Boolean logic, specifically employing basic AND logic, in which both inputs must register as high to yield a correspondingly high output. The ESP32 microcontroller processes the output signal, and the resulting information is displayed on both an LCD screen and a dedicated Telegram application. The prototype achieved a notable accomplishment of 100% accuracy in reading inputs.

Abstract

Detection of veins is a critical aspect of intravenous catheterization, but it is a challenging task prone to errors, which can lead to complications such as discomfort or vessel damage. To address this issue, Vein Viewer, an auxiliary tool that employs an infrared camera, has been used to enhance vein visibility. This device captures a subcutaneous venous map using an infrared camera and then processes the images using a Raspberry Pi to display them in real-time on an LCD. This study aims to improve the use of Vein Viewer by analyzing its performance in relation to cliplimit adjustments and varying distances from the skin surface. Our findings indicate that the clearest images are obtained with cliplimits of 500 at 10 cm, 300 at 20 cm, and 400 at 30 cm. These results provide valuable insights into the optimal use of Vein Viewer and offer a practical approach to improve the accuracy of vein detection and reduce the rate of intravenous catheterization errors, ultimately enhancing patient care.

Abstract

Bleeding during surgery is common in major surgical operations. So, it is not recommended to make an incision using a conventional scalpel. As an alternative to replacing a conventional scalpel, an electric scalpel or know as electrosurgery unit (ESU) is made by utilizing a high frequency whose duty cycle can be adjusted and then being focused on one point is a solution to prevent bleeding. This research will design a bipolar electric scalpel or bipolar electrosurgical unit with a frequency of 210-250 KHz and an input voltage of 50-90 VDC to perform pure cuts on chicken meat samples. The box pulse frequency will be generated from IC 4069. The output of the oscillator generator will read the high and low voltage on the Arduino Nano digital pin. The current will be amplified at the oscillator output and then processed in the inverter driver circuit. The selection of the DC input voltage will use a voltage driver circuit. The inverter driver output and voltage driver will be step-up to get a maximum power of 10.4W with a resistance of 100Ω at a frequency setting of 210 KHz and an input voltage of 90 VDC and a minimum power of 1.4W with a resistance of 100Ω at a frequency setting of 250 KHz and input voltage 50 VDC.

Abstract

A deaf person is someone who has lost the ability to hear so that it hinders the process of language information through his listeners. In Indonesia, most of the population is Muslim and has more than 13,000 people with hearing impairments.In carrying out congregational prayers, it is difficult for the deaf to follow the instructions of the priest's movement. This study aims to make prayer aids technology for the Deaf is to assist in performing congregational prayers. The method used in this tool is to provide notifications in the form of different vibrations at every change in the priest's movement to the Deaf community. The device control system uses Arduino nano FT232RL FTDI FT232. The communication module uses HC-12 SI4463, with 433.4 – 473.0 MHz wireless frequency. The MPU6050 gyroscope sensor is employed for detecting changes in angle or motion, and a micro vibrator motor is used as a vibration indicator. Based on the conducted test, the designed Bracelet performed excellent results. It runs according to its working principle where the Bracelet used by the Imam will send a code, and the code is in the form of a change in the angle to the Bracelet used by the Deaf community in the form of vibration, the vibration at each prayer change will be different. Different vibration notifications on each Shalat movement can help the Deaf know the Imam's movement instructions.Furthermore, the prayer aids technology for the Deaf has a success rate of 89%. Thus, this tool can help the Deaf to perform congregational prayers.

Abstract

Pengukuran terhadap suhu tubuh manusia dapat dilakukan dengan menggunakan termometer badan. Jenis termometer badan yang sudah ada saat ini beberapa diantaranya adalah termometer badan analog dan termometer badan digital. Pada umumnya alat-alat tersebut membutuhkan waktu paling cepat selama satu hingga dua menit sampai didapatkan nilai suhu tubuh manusia, sehingga dibutuhkan cara baru untuk mendapatkan nilai suhu tubuh dengan waktu lebih singkat tanpa  mengorbankan keakuratan. Dalam penelitian ini telah dirancang sebuah alat yang dapat digunakan untuk mengetahui nilai suhu tubuh manusia dengan waktu yang singkat dan menghasilkan nilai pembacaan yang akurat. Menggunakan sensor infra merah dengan seri MLX90614 yang dipadukan dengan Arduino Nano serta tampilan LCD OLED 128x64 merupakan cara yang digunakan untuk membuat termometer tubuh tanpa kontak fisik. Metode penelitian yang digunakan yaitu membandingkan antara alat non-contact thermometer dengan alat pembanding. Alat pembanding ini sebagai acuan untuk mendapatkan nilai presisi dan akurasi yang tinggi. Kedua alat melakukan pengukuran suhu dalam kondisi yang sama.

Abstract

Wanujoyo Lor merupakan salah satu dusun dari 17 dusun yang berada di desa Srimartani yang terletak di bagian Timur Kecamatan Piyungan, Kabupaten Bantul. Monografi dusun yang sebagian besar wilayahnya merupakan areal persawahan, lebih dari separuh mata pencaharian utama penduduk Dusun Wanujoyo Lor merupakan petani yang bekerja menggarap sawah atau ladang dari pagi hingga petang. Permasalahan yang dihadapi oleh warga di RT 01 Dusun Wanujoyo Lor kurangnya pemahaman masyarakat dalam hal menjaga dan memelihara kesehatan terutama dalam hal penanganan rasa nyeri, membuat mereka rutin mengkonsumsi obat-obatan di pasaran. Selain itu, kurangnya kesadaran terhadap pentingnya pemeriksaan rutin terhadap kesehatan pribadi seperti pemeriksaan kadar oksigen dalam darah, tekanan darah, serta berat badan. Padahal hal tersebut penting untuk dilakukan untuk mencegah bertambah parahnya suatu penyakit. Dalam kegiatan pengabdian kepada masyarakat dilakukan penyuluhan guna meningkatkan pemahaman warga dalam hal menjaga dan memelihara kesehatan terutama dalam hal penanganan rasa nyeri, membuat mereka rutin mengkonsumsi obat-obatan di pasaran. Selain itu untuk menumbuhkan kesadaran warga terhadap pentingnya pemeriksaan rutin terhadap kesehatan pribadi seperti pemeriksaan kadar oksigen dalam darah, tekanan darah, serta berat badan guna mencegah bertambah parahnya suatu penyakit. Kegiatan pengabdian masyarakat ini berjalan dengan lancar. Saat ini warga dusun Wanujoyo Lor RT 01 desa Srimartani telah memiliki tempat layanan terapi infra-merah yang dilengkapi dengan dukungan alat cek kesehatan yang dapat dengan mudah diakses oleh warga setempat.
