Abstract

Perkembangan ilmu pengetahuan dan teknologi saat ini telah mengalami kemajuan pesat yang berpengaruhi terhadap kemajuan sistem pertahanan termasuk dalam sistem operasional di satuan TNI-AD. Penggunaan sistem pertahanan senjata biasanya digunakan untuk mendeteksi sumber suara letusan atau tembakan. Penerapan metode back propagation pada raspberry dengan menggunakan sensor microphone boya diharapkan mampu membantu personel yang bertugas untuk mendeteksi sumber suara letusan tembakan. Sensor merupakan alat yang berfungsi untuk mendeteksi adanya perubahan lingkungan secara fisik yang digunakan untuk berbagai kebutuhan sesuai dengan spesifikasi alat yang diinginkan. Penelitian ini menggunakan metode fft yang dapat mengubah time domain menjadi frekuensi domain dengan cepat. Metode back propagation berfungsi untuk mengenali bobot atau presentase jenis suara tembakan SS2. Sensor mikrofon menerima suara tembakan yang nantinya dengan penggunaan raspberry pi 4 akan menghasilkan output yang mempresentasikan suara senjata ringan SS2- V1 pada layar lcd dan speaker. Output yang didapat berupa arah suara tembakan dan jenis suara tembakan.

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.

Abstract

Sistem monitoring indeks WBGT adalah suatu alat yang dirancang berfungsi sebagai pengganti alat WBGT (Wet-Bulb Globe Temperature) yang sudah ada. Penelitian ini dilaksanakan dikarenakan adanya beberapa faktor yang pertama yaitu mahalanya alat WBGT dan yang kedua yaitu pengukuran suhu, kelembaban, dan intensitas cahaya pada jajaran TNI AD saat ini masih menggunakan cara manual. Pada alat ini menggunakan 2 macam sensor yang memiliki 4 parameter hasil yang saling berkaitan untuk menghasilkan data indeks seperti pada alat WBGT. Kegunaan dari masing-masing sensor yaitu sensor DHT21 sebagai pengukur suhu dan kelembaban, sensor DS18B20 sebagai alat pengukur suhu bola basah dan dry temperature. Selain menjadi alternatif untuk mengukur indeks WBGT yang sudah ada dan beredar di TNI AD karena dari segi ekonomisnya, alat WBGT yang dirancang ini juga memiliki indikator lampu dan alarm untuk memberikan peringatan apabila indeks WGBT melebihi batas yang telah ditentukan. Kata Kunci: dry temperature, sensor DHT21, sensor DS18B20, WBGT

Abstract

Abstract: The post of the conflict area in Papua at night is in danger of an enemy approaching silently. Thus, resulting in material and personnel losses. To minimize personnel and material losses, it is necessary to have a silent enemy detector with efficiency and high effectiveness. The purpose of this study is to help post guards in conflict areas so that the level of vigilance at night is higher. For this reason, researchers made a tool that is able to detect enemies at night using geophone sensors by planting them in the ground and sent to the post using the NRF24L01 radio frequency after being processed by Arduino uno. In this study, experimental methods are used to achieve maximum results and will focus on geophone sensors, experiments carried out when the sensors are planted in the ground to detect vibrations that occur when there are humans around the post. The geophone sensor will detect the frequency that occurs when around the postal area there are humans walking. From the frequency data that has been concluded, you will get data that vibrations that occur when humans are around the post that has been processed by Arduino Uno are then sent via radio frequency and a warning will appear on the post in the form of LED lights and buzzer sounds that are like the sound of crickets. With this detection device, the security of posts in conflict areas is more maintained and safer at night. Keywords: Geophone Sensor, NRF24L01, Arduino Uno.
