Keberadaan Kampus Unit 1 UPY berada di Kabupaten Bantul tempat secara historikal di Bantul pernah terjadi gempa besar tahun 2006 yang mengakibatkan korban jiwa dan kerusakan bangunan dengan skala besar di DIY. Pada kurun waktu 5 tahun terakhir di kawasan unit 1 terjadi pembangunan gedung baru hingga diperlukan penelitian untuk melihat kerentanan terhadap getaran seismik. Dari data pengukuran mikroseismik dapat melihat dan memetakan gedung yang rawan saat terjadi gempabumi agar dapat dilakukan pencegahan dan ketahanan gedung. Pada penelitian ini menggunakan alat Seismometer Lennartz Electronic tipe LE 3D/20s. Data yang telah didapatkan kemudian diolah dengan bantuan software Geopsy untuk memperoleh nilai frekuensi dominan dan amplifikasi dengan metode HVSR. Berdasarkan hasil penelitian diperoleh nilai frekuensi dominan (f0) di daerah penelitian berkisar 1.27 Hz-2.79 Hz, Amplifikasi (A0) berkisar antara 1.28-2.05, nilai kerentanan seismik (Kg) berkisar antara 1.445-2.056, dan nilai Peak Ground Acceleration (PGA) berkisar antara 82.04 gal sampai dengan 236.84 gal. Dari hasil pengolahan data yang diperoleh, dapat disimpulkan bahwa nilai frekuensi dominan yang rendah mengindikasikan adanya lapisan sedimen yang tebal, yang berpengaruh terhadap nilai kerentanan seismik. Untuk nilai PGA dilapisan permukaan masuk ke dalam tingkat resiko sedang dua sampai dengan risiko besar tiga dengan intensitas VII-IX MMI yang sebagian besar berada di area gedung perpustakaan dan auditorium UPY.
Regular use of computers in the workspace contributes to suffering from many risk factors associated with musculoskeletal disorders (MSDs). Ergonomic principles is a determining factor of comfort and increased worker productivity at work. Ergonomics is also very important for workers who use computers. Working with computers is at high risk of suffering from a variety of complaints, including having the three biggest risk factors: back posture, repetition, and static strength. Preventive measures can minimize the negative impact of the main risks above. The purpose of this study is to assess and measure the ergonomics of the Internet Marketing Society's workplace workers. This service research uses observational methods from survey results with questionnaires distributed via google form. The total sampling is 33 workers from the Internet Marketing Society. The results show that 54.5% of workers do not know about ergonomics, 75.8% of workers do not use wrist and arm support devices. In the complaint problem, most of the workers experienced muscle pain 27.3% and back pain 24.2%, and 24.2% workers experienced shoulder conditions that were not relaxed while working. Based on these results, it is concluded that workers need to implement the principles of K3 and ergonomics in their work while working with computers.
This study aims to develop an infrared therapy device by embedding the internet of things technology in the research area of therapy devices, especially infrared therapy. Low back pain is a disease that attacks the back muscles that can cause disability and discomfort in activities. This system was developed with an automatic system located in the automation of the lights off and the LM35 temperature sensor, which records the temperature if you feel hot and the timer setting that appears on the LCD and the android interface. This system is based on the internet of things to be monitored from anywhere, anytime. This study consists of an LED lamp, cloud system, and ATmega 328 microcontroller. The study and literature review are carried out following the device development method that embeds the internet of things technology systems in infrared. This study’s result is a prototype design of an infrared therapy device with the internet of things technology that can be used to treat people with low back pain.
