COVID-19 Tracking Applications: A Human-Centric Analysis

The year 2020 will always be remembered with the imprints left by COVID-19 on our lives. While the pandemic has had many undesirable effects for the whole world, one of its biggest side effects has been the fast digital transformation that has taken place, which was already in progress with the Industry 4.0 era. The readily available technology and wireless communications infrastructures paved the way for a myriad of digital technologies for the containment of the disease using mobile contact tracing applications developed by health authority organizations in many countries. The mounting privacy concerns especially with Bluetooth-enabled proximity tracing and centralized tracking technologies used by these applications have given rise to the development of new privacy-preserving contact tracing protocols. Although these new protocols have alleviated the privacy concerns of citizens to a certain extent, widespread adoption is still far from being the reality. In this paper, we analyze existing contact tracing technologies from a human-centric standpoint by focusing on their privacy implications. We present our comprehensive dataset consisting of the contact tracing application usage information in 94 countries and provide results of a multinational survey we have conducted on the sentiments of people regarding contact tracing applications. The survey results demonstrate that privacy concerns are still the leading deterrent for people when deciding whether to use these applications. Nevertheless, it is a globally accepted argument that the most effective and fastest method for contact tracking will be digital technologies free from human errors and manual procedures. Accordingly, it is concluded that a policy of developing decentralized tracking solutions based entirely on user privacy should be followed, in which independent trusted third parties assume the role of authority in the system architecture, if absolutely necessary, in order to effectively combat the pandemic worldwide. An important feature of the systems to be developed to pave the way for widespread use is to provide the users the right to be forgotten

Construction of Chicken Drinking Water Sterilization Device Using Ultraviolet Light Based on ATMega8535 Microcontroller

This research aimed to design of a chicken drinking water sterilization device using ultraviolet light-based microcontroller ATMega8535. After constructing the device, the test that is carried out were running the system according to the procedure, observing the performance of the system that begins with setting the sterilization timer at the minimum position, and recording the results. After the power supply was activated, the potentiometer of timer set to a minimum. The pump was on for 1 minute, then the UV lamp was also active and the process continues to repeat. Potentiometer was set to increase by 50% timer in 5 minutes position, and raised again to 100% at 10 minute position. The control process of this system is carried out by an ATMega8535 microcontroller that regulates the process of draining water from the container to the pipe, the length of time it takes to activate the ultraviolet lamp and the length of time it takes to activate the pump. This device was designed to demolish germs and bacteria in the water. The test resulted in a 100% reduction in bacteria in ultraviolet-illuminated water

Isolation and Analysis of Chemical Components of Garlic (Allium sativum L.) Tuber Essential Oil As Well As Antibacterial and Antioxidant Activity Tests

The essential oil from garlic tubers (Allium sativum L) was isolated by hydrodistillation method using the Stahl apparatus. Garlic tubers were distilled for 4 to 5 hours to produce as much oil as 0.05% (w/ w). The chemical components of essential oil of garlic tubers were analyzed using GC-MS spectroscopy. The GC-MS results showed that there were 11 components with 5 main components, namely diallyl disulfide (44.98%), 1,3-diallyl tri sulfane (13.63%), allyl sulfide (13.06%), methyl allyl disulfide (11.87%), and methyl allyl trisulfide (4.84%). The antibacterial activity of essential oil of garlic tubers with diffusion method to use concentration variation of 5%, 10%, and 15% have strong antibacterial activity against Gram-positive bacteria like Staphylococcus aureus and have a medium to strong antibacterial activity against Gram-negative bacteria like Escherichia coli. The antioxidant activity of the essential oil of garlic tubers with DPPH (2,2-diphenyl-1-picrylhydrazil) showed an IC50 value was 22.863 mg/L and a very strong antioxidant group

SURVEY SANITASI PERUMAHAN DI DESA JUHAR TARIGAN KECAMATAN JUHAR TAHUN 2016

Homes for human beings have the meaning of a place to unwind, rest after tiring to perform daily obligations, as a place to mingle with the family, as a place to protect themselves from danger, as a symbol of social status, a place of wealth. In relation to that, the law of the Republic of Indonesia Number 36 Year 2009 on the Health program states that the highest degree of public health is achieved through the implementation of health development entitled to residence and to have a good and healthy environment.

Penguatan Kelembagaan Pimpinan Ranting Aisyiyah melalui Inisiasi Prosedur Litigasi dan Non Litigasi Penanganan Kasus Kekerasan Terhadap Perempuan

This volunteer effort intends to help the Aisyiyah Branch Leader of the Jember Regency deal with instances of abuse against women. To address cases of abuse against women, both non-litigation and litigation strategies are used. The overall number of participants in all the action was 50 (fifty). Three (3) steps make up the execution of this community service: preparation, performance, and evaluation. There were two activities before the event: (1) Through the distribution of questionnaires, the community service activities confirmed to the Aisyiyah Branch Manager the types of violent cases that had happened and the breadth of the handling efforts that had been made in the working area of the Aisyiyah Sumbersari Branch Manager, Jember Regency. (2) The service project delivery includes data processing from the distributed surveys. (3) The activity's organizer must create the materials necessary by the Aisyiyah Branch Managers in the office of the Aisyiyah Sumbersari Branch Manager, Jember Regency, based on the data acquired regarding the various types of violence. The primary topic of the literature is litigation, or the processes used to adjudicate cases of victimized violence in court system. While the purpose of non-litigation is to help by using alternate techniques without going through legitimate methods. According to the evaluation of the activities, the Aisyiyah Branch Leaders in the Jember Regency-managed Aisyiyah Sumbersari Branch are better able to handle situations of violence against women
