The two-tank water system is common practice for the storage and distribution of water in many homes. Water is transported via a pipeline network from the storage tank (lower tank) to the ...distribution tank (overhead tank) using an electric pumping machine. Due to limited control in the existing pumping system, water wastage becomes inevitable. Determining the quality of water in the overhead tank before supply in the home is still unaddressed. In this work, an integrated Android mobile App and a control system were developed to assess the water quality, perform level check in the overhead tank, and activate intelligent pumping control. An ultrasonic pulse-echo technique was used for water level checks, while the water turbidity and pH signals were used for water quality checks. Three-level control conditions (LC_1, LC_2, LC_3) and two water quality check conditions (QC_1 and QC_2) were devised and used in the intelligent control algorithm of the system. Control valve1 regulates the flushable poor water quality while valve2 regulates the house's supply of good water quality. The absolute relative error between the expected time and the system time of filling the tank level was observed to be less than 10% when the water volume is less than 81%. Hence, distortion in the sensory signals increases and worsen as the water level approaches the ultrasonic sensor position. The poor internet signal network was observed to affect the real-time monitoring and automation of the system control through delay in system responses to commands. However, the average recorded response time of the system is 3 s, and it could be less in the situation of good internet network services.

Information in the form of an agenda made by the teacher is an important thing that parents should know, but the fact is that parents are mostly late in getting all of this information. With the real ...time features that have been developed in mobile applications today, this problem can be overcome. This study aims to implement the push notification function in applications used by parents and teachers in school. This application is useful as a connector that provides an agenda between users, so all parents can find out the information agenda in real time. We are using prototyping method which consists of the stages of gathering needs, building prototyping, evaluating prototyping, coding, system test, system evaluating, and system implementation. The system built runs well that proved by the blackbox testing carried out. The results of the test show that all the features of the system run intact and well.
Hajj and Umrah are worship activities carried out by Muslims around the world. The problem that often occurs during the implementation of the Hajj and Umrah is that pilgrims are often lost and ...separated from the group. Pilgrims also find it difficult to look for prayers because they are still using guidebooks, they have to look for prayers one by one in the feeling of a busy and hot holy land. The case study was carried out at Dago Wisata Internasional. The solution used is utilizing geofencing technology and Firebase Cloud Messaging that allows the process of monitoring pilgrims to be carried out easily and the pilgrims can get prayer notifications in accordance with the location of pilgrims. Research supporting data obtained from interviews with employees of Dago Wisata Internasional and literature studies. Based on testing on the application that has been built, the following results are obtained 93.33% supervisor states that this application simplifies the process of monitoring pilgrims, 84% worshipers claim to be able to ask for help easily from the supervisor using this application, and 86% worshipers claim this application makes it easy for pilgrims in looking for the practice deeds.
Fire due to Liquefied Petroleum Gas (LPG) gas leak is one of the disasters that still often occurs in the community. Community ignorance of safety standards in using LPG gas is one reason. Fires ...can be prevented if at the time of the LPG gas leak can be detected earlier. Therefore we need a system that can monitor the condition of gas leaks and fires remotely. Internet of things (IoT) technology can be applied to this monitoring system so that information on LPG gas leaks and fires can be monitored remotely. The Internet of Things (IoT) based LPG and Fire leak monitoring system is a concept that utilizes internet connectivity between smartphone devices connected to sensor devices. The devices used to support this system include NodeMCU ESP8266 as a microcontroller and as a liaison to the internet, MQ-6 gas sensors and flame sensors as sensors for detecting gas and fire leaks, buzzers as alarms, and fans as neutralizing gas levels in the room. Data obtained by the sensor will be uploaded to the database via the internet and can be accessed through an android application. The results of the design show that the android application can display notifications when a gas leak or fire occurs. In testing the performance of data transmission, the results show that the highest data transmission delay is 64,61 seconds, and the lowest delay time is 61,56 seconds, the highest throughput value is 747,6 bits/second, and the lowest value is 285,4 bits/second.

Every day, we engage in a variety of activities such as shopping, reading, swimming, and so on. Many people in our community, however, are unable to participate in such activities, due to a variety ...of eye problems. Directing a blind person to the optimal position (the center of a spot where there is enough space in all directions such that a blind person avoids various obstacles) is a challenge. This paper proposes wireless bracelets that are able to guide a blind person to the optimal position. The proposed system employs ultrasonic sensors in order to detect various obstacles in an indoor environment. It also makes use of the Firebase database and NodeMCU WiFi module to enable real-time communication with a blind individual. Furthermore, the suggested system includes a novel fall-detection mechanism. The proposed Internet of Things (IoT) system is evaluated in an indoor environment. Experiment results showed that the proposed system could efficiently direct a blind person to the optimal position. In comparison to the current state of the art, the proposed system is simpler, less expensive, and more efficient in determining the optimal position to which a blind person must navigate.
