Abstract

The first-ever Covid-19 virus Pandemic was found in Wuhan, China in December 2019. This virus has become a pandemic and become the cause of death for many people. This Virus spreads rapidly and that's why it becomes every country's concern. The Covid-19 Virus can be detected by a method called PCR Swab Test. The Swab and PCR method can't be separated from defining a suspect result of Covid-19. Even more, Swab tests and PCR have become an important requirement for traveling. But the Test is so costly and takes a long time to get the result where it becomes a new problem. Hence, there is a device called Poltekad Electronic Detector that can detect a suspect of Covid-19 based on Body Temperature, Blood Pressure, Heartbeat, and Oxygen level on blood. All these parameters will be used by a smart system to draw a conclusion and showing it on a Web Server. This research using some of the methods used in sensor calibration thus makes the output of the device is corresponding to the Health Equipment Standard. According to the result of this research, the device could read a parameter and then draw a conclusion about the suspect and also send the data to the Web Server so the data can be accessed from a PC or a Smartphone. The result from the Web Server can be printed in PDF Format.

Abstract

Abstract: Indonesia is an archipelagic country with 17,504 islands, geographically Indonesia is located between the continents of Asia and Australia and the two Pacific and Indian Oceans. In support of maintaining the sovereignty of the Republic of Indonesia, especially the land dimension, equipment is needed to support the main tasks. The majority of the equipment used requires electrical energy in its use. Meanwhile, in carrying out their duties, while maintaining sovereignty in border areas, the geography is in the form of tropical forests with minimal fields of electrical energy as an energy supply. Therefore, researchers develop a source of electrical energy by utilizing footsteps, which is a solution for recharging electrical energy. In developing the tool, the method used is fast charging. The mini generator located on the shoe is expected to be a solution for recharging as a supply of electrical energy for equipment to support basic tasks. Capacitor Bank is used to stabilize the input voltage of the mini generator so that recharging becomes more stable and charging faster.

Abstract

Abstract - The rise of a shooting incident that occurred in the border areas of the Republic of Indonesia is a big loss for the state in terms of personnel. Technological developments can be used as an alternative in the military world to help the role of soldiers so as to reduce personnel losses. This study aims to create a system for detecting the direction and distance of gunshots. This study uses an experimental method. This gunshot detection system also applies the Fuzzy Logic Method which is applied to the Raspberry Pi 4 and Microphone Max 4466 which is expected to detect the direction and distance of gunshots. This Fuzzy Logic method is used as an inference system or decision maker according to the input given. Fuzzy Logic broadly consists of fuzzification, rule base, and defuzzification. Fuzzification is useful for input normalization, so that the input quantity is in accordance with the fuzzy magnitude, namely the value in the range 0 to 1. After that, enter the rule base where in this step, the input set is compared with the rules or provisions of sound decibels so that it can be classified whether the distance and the direction of the captured sound is in the data range that has been programmed, in this step the signal is analyzed how much decibel sound SS2-V1 is by the MAX 4466 sensor. The conclusion is done by defuzzification, so the final result is that the closest distance to a gunshot at 1 meter is 250 Decibels.

Abstract

Electricity is one of the essential needs for society today, serving as a primary economicresource. The use of electricity in household sectors reached 50.80% in 2020,contributing to the total electricity consumption in Indonesia each month. To raiseawareness about excessive electricity usage leading to inflated electricity bills, there is aneed for a remote monitoring and control device, based on the Internet of Things (IoT),specifically targeting electronic appliances that consume electricity.Addressing this issue, a research study titled "Design of Electricity Monitoring SystemUsing NodeMCU ESP8266 and PZEM-004T for Controlling Electricity Usage" wasconducted. The energy usage monitoring system is implemented in a terminal socketdevice capable of displaying power consumption through a module. Additionally, thisterminal socket can be connected to the internet, allowing users to view electricity usagedata on the ThingSpeak website. The necessary tools and materials for designing themonitoring and controlling system include a laptop, NodeMCU ESP8266 module,PZEM-004T sensor, relay (Rlay), OLED display, power terminal, plug (Stekker), andjumper cables.Based on testing using the blackbox method, the system has demonstrated effectivemonitoring and control of energy usage. It was observed that the power consumptionstated for an electronic device may differ from the actual power consumed. Thisdifference could be attributed to variations in the stated power consumption informationcompared to the actual power consumption.Keywords: households, NodeMCU ESP8266, PZEM-004T, IoT, electricity monitoring..

Abstract

The Bekang Corps, a vital component of the Army responsible for logistics and transportation, plays a crucial role in maintaining the military's operational readiness and mobility. In the intricate landscape of military operations, the seamless integration of strategy, logistics, and tactics becomes imperative for success. Integrated logistical support, encompassing maintenance, supply, personnel, education, and training, and base facility support, serves as the backbone of effective military operations. However, the manual monitoring of underground fuel tanks at Storage and Supply Points (SPBT) presents challenges in terms of potential errors, time consumption, and significant efforts. The aim of this research is to address these issues by focusing on leveraging Internet of Things (IoT) technology to design and implement a monitoring application specifically tailored for the SPBT environment within the Army's Bekang Unit. This research method is aimed at providing a real-time solution for efficiently monitoring and managing fuel levels. By integrating the Float Level Switch sensor and NodeMCU ESP 8266 microcontroller, this research establishes a foundation in IoT. The Android application, developed using Android Studio, serves as the user interface, while Firebase functions as the real-time database, facilitating seamless communication and data exchange. The results of this research are the successful implementation of this IoT-based solution, which not only enhances the accuracy and responsiveness of fuel level monitoring but also contributes significantly to military operational efficiency. The anticipated significant contribution of the application includes the enhancement of military operational efficiency, the reduction of human error risks, and an increased sense of responsibility regarding fuel availability for operational needs.
