The decrease level of vital capacity can be restriction, obstruction or both of them. Some factors, like non jobs and environment can lead the decrease level of vital capacity. The goals of this research is knowing all factors that have associated with vital capacity of street sweeper in Kecamatan Medan Denai. The research was conducted on September 2018. The factors of this research are work period, exposure period, mask utilization, employment history, disease history, smoking and sports habits. The total sample of this research are 67 workers. The method of this research was cross sectional. Data was collected by using research instruments such as peak flow meter and questionnaires. The results showed that workers with more than 5 years of service experienced a decrease in KVP as many as 62 people (92.5%) and workers who did not use masks decreased by 53 people (79.1%). Based on the results of statistical tests, it is known that the variables of working period and the use of masks are associated with a decrease in KVP. To reduce the decrease level of street sweeper’s vital capacity, it is recommended that workers are leave the workplace right after the job is done and use mask at work site all the time.

WHO memperkirakan sekitar 15% dari seluruh kehamilan akan mengalami komplikasi yang berhubungan dengan kehamilan, baik secara langsung maupun tidak langsung. Komplikasi langsung meliputi perdarahan, infeksi, eklamsia, partus lama dan komplikasi abortus, sedangkan secara tidak langsung anemia sebesar 51%.

Tiga bentuk opioid receptor antagonist yaitu naltrexone (ReVia), naloxone (narcam), dan nalmefene (Revex). Dimana peran dari opioid receptor antagonist dapat mengurangi atau menghilangkan kecanduan. Penggunaan opioid receptor antagonist yang saat ini yang telah mendapat persetujuan dari Food and Drug Administration (FDA) adalah naltrexone oral yang digunakan untuk pengobatan ketergantungan alkohol dan dapat dipergunakan untuk proses rapid detoxification dan untuk menghambat efek dari opioid. Diharapkan akan mampu untuk menangani kasus-kasus yang berhubungan dengan psikiatri maupun gangguan adiksi lainnya. Pada prinsipnya terapi dengan menggunakan Opioid receptor antagonist akan memberikan hasil yang maksimal apabila dilakukan kombinasi dengan intervensi non farmakologi lainnya.

Sensasi, persepsi dan kognitif adalah tiga hal mendasar dalam penyampaian proses informasi pada manusia. Sensasi menggambarkan adanya suatu proses atau adanya suatu stimulus yang cepat dari neuron sensorik dimana persepsi ikut terlibat mengatur dan mengevaluasi sensasi untuk mendapatkan informasi yang berasal dari dalam dan luar.Setiap informasi yang kita dapatkan di dunia ini akan dapat sampai melalui proses indera yang memberikan informasi kepada kita tentang segala sesuatu yang kita butuhkan untuk dapat mengartikan atau mempersepsikan berbagai peristiwa yang terjadi dan mengantisipasinya di masa depan. Kognitif mengacu pada suatu proses yang kompleks melibatkan memori, fungsi eksekutif, orientasi dan atensi seperti dalam proses berbahasa, pemecahan masalah dan proses berpikir yang dapat digunakan atau diterapkan sebagai rencana dan strategi dari proses sensasi dan persepsi.

The phenomenon of the outbreak Covid-19 pandemic in a number of countries, including Indonesia. This condition not only affects the condition of a country, hinders social interaction among community, and also has been impact on the health condition of every human being. To avoid the wider spread of Covid-19, the Indonesian government adopted a policy of social distancing and physical distancing in the form of staying at home, working from home, studying, and worshiping at home.The research’s design used Analytical Observational with Cross Sectional Study design. The independent variables of this study are the application of physical distancing, the application of hands washing behavior and consumption pattern of fruits and vegetables. The amount of sampling in this study were 109 respondents spread across Bogor Regency, West Java using accidental sampling’s and analyzed using chi-square. The results of the study illustrate that efforts to prevent Covid-19 by implementing physical distancing, hands washing behavior and vegetables fruits consumption patterns can reduces the risk of being exposed to Covid-19 in Indonesia. The Indonesian people must apply the Covid-19 prevention appeal that has been set by the government to reduce the spread of Covid-19 in Indonesia.

Acute Respiratory Infections (ARI) are a health problem that has not been handled properly in Indonesia,every year the incidence of acute respiratory infections is still high, which can be fatal, namely death. Severalfactors cause acute respiratory infections such as nutritional status, dust exposure, length of exposure todust, and years of service for workers in industries who have a high risk of acute respiratory tract infectionproblems. This study aims to determine the risk factors for acute respiratory infections in the industry. Thisstudy uses a cross-sectional approach with a sample of 89 respondents, where the results will be analyzedusing the chi-square test. The result of this study is that there is a relationship between nutritional status,dusty workspace, length of exposure to dust, and length of work with the incidence of acute respiratoryinfections in industrial workers. Based on the results of this study, it is hoped that workers and the industrywill pay attention to the use of PPE to minimize dust exposure to workers in the industry.

The Artificial Neural Network in this study has been used to predict drug users by using the backpropagation method with the Matlab 7.7 software program. The variables consist of the number of drug users, the type of drug used and the employment status of drug users. The data input from 2010 to 2012 while the target data is 2013 data consequenlty if input data and target data are processed on artificial neural networks will produce output that can predicts 2014 drug users. Predictions actually consider the value which has not been seen in the future based on past data. Prediction is the process of predicting something by correcting the previous action. To predict a condition, it requires proper calculation to answer the problem. The calculation can use artificial neural networks with the backpropagation method.

In this modern era, information technology is very influential in many ways, especially in the business and business world. Computer is a device that is needed for data processing, so the data processed can be effectively and efficiently to provide information needed by individuals, companies, and agencies. Clustering is a method for finding and grouping data that has similarity between one data and others. In the clustering algorithm, data will be grouped into clusters based on the similarity of one data to another. The principle of clustering is to maximize the similarity between members of one cluster and minimize similarities between different cluster members. The most well-known category of clustering algorithms is Hierarchical Clustering. As well as PLN (State Electricity Company), where PLN is a state-owned enterprise (BUMN) that provides electricity services to all communities and all circles, both private and business entities whose job it is to serve users in electricity. Services will be maximized and can be accessed by all parties if in the service there is a role for the media as a assistant in conveying information to all circles. This information will be right on the target if the information is processed from a reliable source. PT PLN (Persero) Krueng Geukuh did not yet have a load data collection system that makes staff still did data collection by manual methods. The result of this study shows the system of 2 hour load cluster data grouping using hierarchical clustering of PT PLN (Persero) Krueng Geukuh is an effective solution to help staff record computerized loads and can increasing the work performance in data collection. Designing systems of Grouping Data Load 2 Hours Substation Using Hierarchical Clustering PT PLN (persero) Krueng Geukuh was built by using PHP so it has a more attractive appearance and uses a MySQL database so that load managers become more effective.
