Abstract
Elderly persons falling while showering or bathing is currently common happenings. The fall is due to various reasons. The worst part is due to deadly attacks such as heart attack or what commonly is called as stroke where the elderly lose consciousness. If the attack is handled within a certain period, the elderly could survive and recover fully. Beyond that period there could be grave consequences. Due to age the agility and resilience of an elderly is limited and often need assistance in order to overcome the incident. Providing human assistance within a bathroom or its vicinity is not an easy matter due to certain limitation. This research strives to provide emergency warning system that can invoke justifiable human action to provide assistance. The assistanceis often lifesaving within or in the vicinity of the bathroom where the accident is happening. The warning system uses a sensor that identifies movements within the confines of the elderly movement. The research object is a shower room normally found in a non-luxurious apartments or landed houses. As soon as no movement is detected awarning indicator is raised. To detect movement a common detector known as PIR is selected. The indicator from PIR is transmitted using LoRa as the communication infrastructure. LoRa will act as the sender and recipient of data from the sensor. The LoRa receiver will send an audible alarm and an SMS message as warning to the family member in charge. All system within the shower room use low voltage batteries. Electrical power must be avoided due the hazard it could cause, Measurements showed the most likely blind spots. The system functions as designed.

Published: August 2021

Abstract
Milk is an optimal liquid medium for the growth of microbial contaminants due to the high nutritional content. Therefore, the sterilization process is needed to make the milk save to be consumed as well as to extend the milk’s shelf life by inactivating microorganisms. A non-thermal plasma system has been utilized as a new alternative sterilization method for food products. Non-thermal plasma generates free radicals, reactive oxygen species (ROS), and reactive nitrogen species (RNS) that contribute to bacterial cells inactivation. This review focused on the factors that affect the non-thermal plasma efficacy to microbial inactivation during the development of milk cold sterilization. The plasma effectiveness in inactivating bacteria could be affected by the attributes of plasma treatment time, the applied voltage, working gas and the type of plasma system. The non-thermal plasma system successfully applied to reduce the number of total bacteria in milk and prolong the shelf-life.
