Abstract

Tangan adalah salah satu bagian tubuh manusia yang sering digunakan. Aktivitas berlebihan bisa menjadikan otot pada tubuh manusia mengalami kelelahan sehingga mengakibatkan nyeri. Penyembuhan nyeri otot bisa dilakukan menggunakan salah satu alat medis yaitu therapy infrared. Terapi infrared adalah penyinaran lampu pijar inframerah ke bagian tubuh yang menembus bagian kulit sehingga dapat melancarkan peredaran darah. Penggunaan metode VAS sebagai nilai indikator tingkat nyeri. Metode ini dilakukan dengan uji coba ke pasien di RSUD Jombang. Penelitian ini dilakukan dengan 3 percobaan yaitu pasien diminta untuk melakukan handgrip 10, 20 dan 30 kali, dan masing-masing akan diukur tegangan sensor ototnya baik sesudah disinari infrared maupun sebelum disinari, sehingga dihasilkan data sebagai berikut : jika memakai 10 handgrip terjadi penurunan tegangan otot dari 250,784 mV menjadi 240,833 mV, jika pasien memakai 20 handgrip dihasilkan penurunan tegangan otot dari 255,375 mV menjadi 246,94 mV dan percobaan memakai 30 handgrip dihasilkan penurunan tegangan dari 278,026 mV menjadi 264,566 mV, sehingga terdapat hasil yang signifikan antara sebelum dan sesudah penyinaran inframerah

Abstract

Abstrak Komunikasi menjadi hal terpenting dan utama bagi kehidupanmmanusia dan tidak semua orang dapat menggunakan indra pendengarannya dengan sempurna. Penyembuhan terhadap indra pendengaran bukan solusi yang efektif. Dikarenakan terdapat dua faktor yang mempengaruhinya yaitu (1) faktor keturunan dan biaya yang dikeluarkan sangat mahal. Bahasa isyarat menjadi media komunikasi yang digunakan oleh anak tunarungu/wicara untuk meminimalisir keterbatasan yang mereka miliki berupa keterbatasan pengucapan dan pendengaran. SIBI (Sistem Isyarat Bahasa Indonesia) merupakan bahasa isyarat yang baku sehingga memudahkan untuk berkomunikasi. Akan tetapi fakta dilapangan menunjukkan bahwa tidak semua dapat mengerti dan menggunakan bahasa isyarat. Sistem komunikasi yang berbasis speech recognition menjadi media komunikasi yang tepat. Sistem ini dapat memudahkan berkomunikasi antara anak tunarungu/wicara dengan anak normal yang harapannya tidak ada lagi perbedaan atau diskriminasi terhadap anak berkebutuhan khusus. Pada penelitian ini kami menggunakan sistem pengenalan suara dan Model Hidden Markov (HMM). Cara kerja sistem ini yakni menggunakan input suara kemudian diproses oleh PC/Laptop. Adapun outputnya berupa teks kalimat dan video isyarat hasil terjemah dari input suara yang diberikan. Sofware yang kami gunakan ialah python 3.6.5 dan Qt-Designer sebagai interfacenya. Hasil penelitian menunjukkan tingkat akurasi yang dihasilkan sangat baik, sedangkan apabila terjadi noise disekitar maka tingkat akurasi menjadi sedikit berkurang yakni 85%. Dengan demikian penelitian memiliki nilai manfaat dan kontribusi kepada anak tunarungu/wicara. Media ini memudahkan siswa agar dapat berkomunikasi dengan anak normal pada umumnya. Kata Kunci — Komunikasi, SIBI, Speech Recognition, Hidden Markov Model. Abstract Communication is the most important and foremost thing in human life, but not everyone can use their sense of hearing perfectly. The healing of sense of hearing is not an effective solution, because there are two factors that influence it, namely (1) heredity and (2) the very expensive cost. Sign language is a communication medium used by deaf/mute children to minimize the limitations they have in the form of speech and hearing limitations. Sibi (Indonesian sign system) is a standard sign language that makes communication easier. However, the facts in the field show that not all normal children can understand and use sign language. So that, a communication system based on speech recognition is made. This system can make the communication between deaf/mute children and normal children becomes easier and it is expected that there will be no more differences or discrimination against children with special needs. In this study, we used a speech recognition system and the hidden markov model (HMM). The way this system works is using voice input which is then processed by a PC/laptop. The output is in the form of sentence text and sign video translated from the given voice input. The sofware we use is python 3.6.5 and Qt-Designer as the interface. The results of the study show a very good level of accuracy, while if there was noise around, the accuracy rate would be 85%. Thus, this study has the value of benefits and contributions to deaf/mute children to be able to communicate with normal children in general. Keywords — Communication, SIBI, Speech recognition, Hidden Markov Model.

Abstract

The Community Partnership Program (PKM) is a community service program that carried out in the village assisted by the Electrical Engineering Study Program at the University of Trunojoyo Madura. the program is a continuation of the Real Work Lecture program (KKN) which is carried out in the Even semester 2019/2020 involving students, as well as village officials. The village of Sabiyan is located on the coast of Madura where the average population still relies on electricity for daily activities. The problems faced by the people of Sabiyan village Bangkalan Regency are: the people of Sabiyan Village do not yet have the knowledge and skills to utilize renewable energy, lighting facilities are still limited so that not all citizens can get electricity, the price of Basic Electricity Tariff (TDL) is higher so it is necessary renewable energy reserves. With these problems, it is necessary to have a hybrid power plant training. Based on the results of the pre-test conducted on the training participants, the average value was 62.50 and the post-test value was 75.83, with a paired sample correlation of -13.33 so that it could be concluded that there was an increase in knowledge after the training was held

Abstract

The measurement of the quality of the density of fuel oil is one of the mandatory activities in the management of the fuel oil supply station (SPBU) business. Density quality test is Pertamina’s way to maintain the quality or standard of fuel that will be used by gas station producers. Measurement of the quality test of the standard density of fuel used at gas stations is conventional or manual measurement using a hydrometer and thermometer. In this final project, a design tool for quality fuel oil density test is made which is useful for maintaining the quality of Pertamina’s fuel when distributed to gas stations by using parameters of density and temperature. This research aims to produce a quality density test tool for fuel in accordance with the standard density set by Pertamina using the ATMEGA16 microcontroller-based hydrostatic pressure method and the Sturdy PC521 USB Webcam Camera as a detector for the height of a liquid and the MLX90614 sensor as a temperature detector. Because the parameters of this method can only be used in ideal conditions, to get the density according to the measurement standards of Pertamina, the combination value for Lux needed by the camera and the camera's viewing distance is with the light intensity 54-59 Lux with a webcam camera distance of 40cm facing the object (Fuel Oil). Output processing from the Sturdy PC521 Usb Webcam Camera and MLX90614 sensor will be displayed in the Delphi XE7 GUI.
