Abstrak—Pergerakan lengan pada saat mengayun akan menghasilkan beberapa besaran yaitu energy, gaya, dan daya. Besaran-besaran inilah yang banyak diteliti, terutama untuk dunia olah raga dan dunia kesehatan. Penelitian pergerakan lengan di dunia olah raga dilakukan untuk meningkatkan performa atlet sehingga bisa mendapatkan prestasi yang optimal. Masalah yang timbul pada penelitian di bidang biomekanik adalah menyangkut bagaimana cara pengukuran dan pengolahan data hasil penelitian. Tujuan dari penelitian yang sedang dilakukan adalah mengukur Gaya, Energy dan Daya pada lengan saat melakukan aktivitas gerakan tangan. Metode pengukurun yang digunakan adalah dengan mengukur arah vektor sensor wiimote yang dipasang pada telapak tangan kemudian pada saat lengan kita bergerak direkam menggunakan kamera, hasil dari rekaman pergerakan tangan kemudian diolah menggunakan program Mathlab. Ada dua subyek dengan berat badan yang berbeda pada percobaan yang diukur dalam penelitian ini.Hasil dari pengukuran gaya, energi,dan daya pada subyek pertama adalah gaya terukur 44,644 Newton, energi terukur 419 Joule, daya terukur 1323,14 Kg.M2.S-3. Hasil dari pengukuran gaya, energi,dan daya pada subyek kedua adalah gaya terukur 44,644 Newton, energi terukur 456 Joule, daya terukur 793,04 Kg.M2.S-3.Kata kunci: biomekanik, gaya, energi, dayaAbstract—The movement of the arm when swinging will produce several quantities, namely energy, force and power. This magnitude has been widely researched, especially for the world of sports and the world of health. Research on arm movements in sports is carried out to improve athlete performance so that they can get optimal performance. Problems that arise in research in the field of biomechanics are related to how to measure and process research data. The aim of the research being carried out is to measure the Force, Energy and Power on the arm during hand movement activities. The measurement method used is to measure the vector direction of the wiimote sensor attached to the palm of the hand, then when our arms move it is recorded using a camera, the results of the recorded hand movements are then processed using the Mathlab program. There were two subjects with different weight in the experiment measured in this study. The results of the measurement of force, energy, and power in the first subject are the measured force 44.644 Newtons, the measured energy 419 Joules, the measured power 1323.14 Kg.M2.S-3. The results of the measurement of force, energy and power in the second subject are the measured force 44.644 Newton, the measured energy 456 Joules, the measured power 793.04 Kg.M2.S-3.Keywords: biomechanics, force, energy, power

The condition of human health can change overtime. It can be affected by lifestyle and daily diet, as well as attacks from mutated viruses and bacteria. The emerging problem is the lack of healthy living behavior practiced by Indonesia people, so that viruses, bacteria and microorganisms can stick to the human body. The purpose of this research is to design a sterilization container to sterilize items that are used daily. A sterilizer to eradicate germs by utilizing UV-C lighting and a disinfectant that can be used. An important factor to raise the public awareness about the importance of cleanliness is the necessity to pay attention to aspects affecting the public hygiene, namely access to adequate sanitation, habit of washing hands, and sterilizing goods. An attempt to sterilize goods after we use them is by using Sterilization Container. This medical device has the objective of sterilizing goods, either directly or indirectly. In this case, the container is very useful as a preventive measure and maintains cleanliness from bacteria and viruses that could stick to human body and clothes. Sterilization Container can be defined as a space that is expected to eliminate microorganisms. In this research, entitled ‘Sterilization Container Using UV-C’, UV-C lamp was used to modify the container with additional disinfectant spray by pressing the button according to the needs.

Mayangsari, Kalipancur Village, Ngaliyan District is an area with the potential to experience river water overflows during high rainfall. This condition causes the community to be at risk of being late in evacuating goods or saving themselves because a simple, independent, and easy-to-operate early warning system is not yet available. This community service activity aims to implement a river water level rise early detection tool based on a float switch as an early warning facility that suits the needs of the community. The implementation method includes three stages, namely 1) socialization regarding mitigation and flood risk reduction, 2) installation of an early detection tool that works mechanically using a float switch without requiring an internet network so that it is easy to operate and maintain, and 3) training on the operation and maintenance of the tool for neighborhood administrators and residents. Activity evaluation was carried out through tool function tests and observation of participants' abilities in operating and maintaining the installed system. The results of the activity show that the tool is able to activate the buzzer automatically when the water surface reaches a warning limit of about one meter according to the set settings. Based on the results of function tests on-site, the system can work according to the design and be utilized by residents as an early warning medium. In addition, the community has understood how to operate and maintain the tool so that the system can be used independently. The implementation of this tool provides an alternative early warning system that is simple, easy to maintain, and supports community preparedness in facing potential floods in the local environment.

Medical waste presents a serious threat to health and the environment if not properly managed, especially in clinical facilities that require high hygiene standards. Manual waste disposal is still commonly practiced, which increases the risk of cross-contamination and reduces operational efficiency. This research aims to design and develop an automated and hygienic SmartBin system for medical waste using Artificial Intelligence (AI) and edge computing technologies without relying on internet connectivity. The system employs distance and weight sensors controlled by an Arduino Uno R3 microcontroller, along with a local image recognition module to classify medical waste based on type. All classification and system responses are processed locally to ensure fast and independent operation. A notification feature using visual and audio indicators is included to alert staff when the bin is full or when hazardous waste is detected. Testing conducted in a simulated clinical environment demonstrated a classification accuracy rate of 92% and reduced direct human contact by up to 85%. This study concludes that the SmartBin system, powered by AI and edge computing and supported by the Arduino Uno R3, offers an effective solution for improving hygiene and safety in medical waste management.
