The construction sector plays an important role in a country's economy. This is because construction projects such as the construction of buildings, roads, bridges and other infrastructure are one of the benchmarks of economic progress and civilization of a country. Work accidents on construction projects can cause work to stop and result in financial losses and decreased work productivity. According to the Minister of Manpower in 2018 the number of work accidents has increased from the previous year even from the data of the Central Statistics Agency stating that the majority of construction workers are junior high school graduates and below. This is one of the factors causing the increase in occupational accidents in the construction sector. Losses from work accidents are also included in workers' losses, damage to equipment and materials wasted due to work accidents. Occupational health and safety (K3) risk control is very important as a preventive effort to prevent a bigger event. One such control is the use of Personal Protective Equipment (PPE) or more commonly called personal protective equipment (PPE). The existence of PPE is important for workers to minimize the impact of accidents so that each company is obliged to use PPE. This study aims to minimize the number of work accidents in Indonesia, especially in the construction sector. The method used in making the body vest is the addition of an airbag by applying the fall detection algorithm to the K-Nearest Neighbor (KNN), which is to calculate the Euclidean distance which is the distance between the sample and training data and then determine the k nearest data from the sample so that the sample can be classified on the sensor and microcontroller. The way it works is when a collision or a hard collision occurs, workers will generally be thrown or dropped then there will be a change in the acceleration of the position of the body wearing a body vest. The change in acceleration triggers the development of airbags on the body vest. This is expected to reduce injuries to vital organs in the worker's body.
<div class="page" title="Page 1"><div class="layoutArea"><div class="column"><p><span>Deafness is a condition in which a person cannot hear due to a disturbance in his hearing organs. In communicating, most of the deaf sufferers only receive hearing aids. WHO (World Health Organization) initiated the Sound of Hearing 2030 by preventing hearing loss by 50% in 2015 and 90% in 2030. The main objective of Sound of Hearing is to develop a comprehensive, inclusive, and sustainable ear care program. Various studies on tools for deafness have been developed. However, this tool is only used to help deaf hearing but not to help speech learning (learn to speak). Thus we need hearing aids and speech learning tools for the deaf. This tool can be a government program, namely supporting a diffable-friendly Indonesia. The tool is designed like a headband, where the headband is composed of a row of vibrating modules that will be connected to the Google Assistant on a smartphone, so that any sound received by the Google Assistant will be sent to the tool to be converted into a vibration pattern. It is from these vibration patterns that a deaf person will get experience in recognizing sounds and learn to speak based on the vibration patterns that are formed. With the design of this tool, it hoped that it can help deaf people and get support from the community and government to create a diffable-friendly Indonesia. </span></p></div></div></div>
