Pengukura Suhu dengan Ir MLX90614 dan NoDeMCU dan Membandingkan dengan Ds18B20 untuk pencegahan Covid 19

This research was carried out by comparing the DS18B20 sensor and the MLX 90614 sensor to detect the accuracy of detecting human body temperature which is used to detect Covid 19 symptoms. In this experiment, 10 trials were carried out with different human segments detected using the sensor. In the experiment, it was found that the MLX90614 sensor is more suitable to be used for development with an IoT-based system because it does not need to come into contact with the skin of the human body. The MLX90614 sensor will detect the temperature and change it to one Celsius unit then send it to the firebase database which will then be picked up by the android application which is held by the security officer so that the temperature can be known remotely. When the temperature is more than 38.5 Celsius it will turn on the buzzer sound which can be heard from a distance which indicates the temperature is above 38.5 Celsius and on android will also display a danger sign

Rancang bangun sistem deteksi suhu tubuh dan hand sanitizer nirsentuh pada prototype pintu geser otomatis

Dalam situasi pandemi Covid-19, roda perekonomian harus tetap berjalan dengan mengedepankan protokol kesehatan. Melansir dari keputusan menteri kesehatan bahwa setiap kantor di Indonesia yang tetap melaksakan Work From Office selama PSBB berlangsung maka harus melakukan pengukuran suhu tubuh, menyediakan hand sanitizer dengan konsentrasi alkohol minimal 70% atau menyediakan sarana cuci tangan di depan pintu masuk. Masalah yang sering terjadi adalah pengukuran suhu tubuh masih dilakukan secara manual oleh satpam kantor, dan tidak terbiasanya para karyawan untuk menggunakan hand sanitizer. Sebagai upaya pendisiplinan karyawan, maka dirancang prototype pintu otomatis yang hanya bisa terbuka jika suhu tubuh normal dan karyawan sudah menggunakan hand sanitizer. Deteksi suhu tubuh dilakukan menggunakan sensor suhu MLX90614 dan deteksi objek tangan menggunakan sensor infrared. Pintu geser digerakkan oleh Stepper Motor NEMA 17, pintu secara otomatis akan terbuka ketika suhu terdeteksi normal, jika tidak maka buzzer akan berbunyi dan pintu tetap tertutup. Hasil dari penelitian ini memperoleh hasil pengujian keakuratan sensor suhu MLX90614 sebesar 96.8%, posisi tangan optimal yaitu posisi tangan menengadah dengan jarak 1cm terhadap sensor, dan volume hand sanitizer yang cukup untuk mengcover seluruh telapak tangan dewasa adalah pada delay 500 ms yaitu sebesar 2.2991 gram. During the Covid-19 pandemic, the economics activities must go on with strict health protocols. From the recommendation of health ministry, that every office in Indonesia that still performs Work From Office during the pandemic, temperature measurements must be carried out at the entrance to the office and hand sanitizer that contains minimum of 70% alcohol or hand washing facilities must be provided as well. The problem is that body temperature measurements are still done manually by security officer, and some employees are still not familiar to use hand sanitizer periodically. As an option to make employees discipline, a prototype of automatic door is designed in this research. It can only open if the body temperature of employee is normal and the employee has used hand sanitizer. Body temperature detection is carried out by using the MLX90614 temperature sensor and hand object detection will utilize infrared sensor. The sliding door is driven by the NEMA 17 Stepper Motor, the door will automatically open when the temperature is detected normally, otherwise the buzzer will sound and the door will be still closed. From the testing results in this research, the accuracy of the MLX90614 temperature sensor is 96.8%, the optimal position of the hand is 1 cm from the sensor with looking up position. And the volume of the hand sanitizer that is sufficient to cover all adult palms with 500 ms delay is 2.2991 grams.

A strategy choosing method for solving the problem of a guard movement while searching for a criminal under condi-tions of uncertainty

The work is devoted to the issue of the complex use of technical means and physical security forces while ensuring the safety of several objects located in the controlled area. The method proposed is for solving the problem of choosing a strategy for searching for a criminal by a security officer while minimizing the time of knowing the direction of movement of the first one to one of the two objects. The proposed method is based on a criminal search strategy implemented by the security guards movement control system, which includes two straight sections of their path, which are formed based on information from the security alarm sensors. A mathematical model has been developed for calculating the parameters of controlling the movements of a guard and an algorithm for the control system operation, which makes it possible to implement an optimal search strategy depending on the location of objects, a guard, a criminal, and information from technical means of protection.

“Concepts of Konstantine Gamsakhurdia`s “Moon`s Abduction”

“Moon`s Abduction” by Konstantine Gamsakhurdia is a very important text written in the Soviet Georgia. The writer created monumental literary landscape in the period of so called “socialist realism” literary style. The novel makes a great demand on the reader`s erudition, on his capacity to understand the complex allusions, literary, philosophical and mythological, that characterize Gamsakhurdia`s prose. The present article deals with the world-outlook of Soviet and Post-Soviet literary critique – on the background of the publicistic letters of the outstanding critics Beso Zhghenti and Soso Sigua. The novel clears up the writer`s attitude to the revolution, socialism, collectivization of agriculture, person`s role as a member of society. The Soviet and Post-Soviet critics world-outlooks are absolutely different. By the Soviet critic (Beso Zhghenti) the novel is an excessive apologia of Soviet system, of Soviet state-building, a positive character (hero) is Arzakan Zvambaia, the security officer, the ossicial of Cheka, Bolshevism is better than traditional life of Georgia, civilization is better than culture. By the Post-Soviet world-outlook (Soso Sigua) the novel is a reflection of tragedy of the Georgian nation (because of negation of Georgian traditions, unique Georgian culture), a positive character is a prince Tarash Emkhvari, cultural and well-educated person; Bolshevizm is tragedy. Literary, philosophical and mythological allusions characterize Gamsakhurdias literary heritage (verses, short-stories, novels). The article deals with the world-outlook of the author. The official of Cheka Arzakan is a patricide, another official Arlan cut the centuries-old sacral tree - Bolhevizm hates roots and traditions. There are a lot of mythological characters reflected in the novel (Aramkhutu-Amirani, Sacral-tree, Mezir – Sacral serpant…). A reader feels the influence of Nitcze and Bergson world-outlook, passages from Hesiod`s “Theogony” and Appolonios from Rodoss “Argonautica.”The novel of Konstantine Gamsakhurdia is one of the best reflections and the best samples of Georgian novel of the 30s of the 20th century epoch.

Feeling Unsafe at School and Associated Mental Health Difficulties among Children and Adolescents: A Systematic Review

This study systematically reviewed the literature on perceived school safety. We investigated the prevalence, factors and associated mental health difficulties, as well as cross-cultural findings. Five databases were searched up to 9 February 2021 for peer-reviewed papers published in English. We included quantitative studies that explored the perception of school safety among children and adolescents. The reference lists of the selected papers were also searched. We conducted a narrative synthesis of the included studies. The review included 43 papers. The mean prevalence of the students who felt unsafe at school was 19.4% and ranged from 6.1% to 69.1%. Their perceived safety was associated with a wide range of personal, school, and social factors. Not feeling safe at school was related to being victimized and mental health difficulties, including depressive symptoms and suicidal behavior. Higher perceived school safety was associated with measures such as the presence of a security officer and fair school rule enforcement. The results showed the lack of cross-cultural studies on perceived school safety. Empirical studies are needed that examine the mechanisms of school safety, using valid measures. A clear definition of school safety should be considered a key aspect of future studies.

Perceptions of Hospitality and Safety Are Two Sides of the Same Coin

Entering a building is a ‘moment of truth’ and may invoke feelings of hospitableness. Physical environments and staff behaviour deliver ‘clues’ that may result in the experience of hospitality. The focus in a reception area may be on mitigation of risks, or on a hospitable atmosphere, with either a host or a security officer at the entrance. However, the division of tasks to either the pleasing host or the controlling security officer to a certain extent disavows the overlap between perceptions of hospitality and safety. This exploratory qualitative study combines a group interview with three managers responsible for hospitality and security in reception areas and Critical Incidents by staff and visitors (N = 51). Thematic coding was based on The Egg Aggregated Model and the Experience of Hospitality Scale. Results show that hospitality and safety are indeed two sides of the same coin. Usually people do accept security measures, provided that staff act in a hospitable way. A lack of security measures may seem ‘inviting’, but also decreases the perception of care for your visitor, and may cause uncertainty and therefore decrease comfort. A correct risk perception, flexible appliance of security measures, and a friendly approach connect aspects of ‘safe’ and ‘hospitable’ sentiments.
