“…To overcome this challenge, the idea of adopting wireless transmission was suggested. Wireless transmission system is the use of Radio Frequency (RF), which is one of the electromagnetic wave frequencies from around 3KHz to 300GHz, for signal transmission in wireless communication as opposed to communication via electric wires [2]. Wireless exploders present opportunities for demolition exercises without the need for physical wire connections between the exploder and the unserviceable stores [3].…”

YAMUGAG-20 Exploder is a Radio Frequency (RF)-based wireless exploder system designed and constructed specially for the Nigerian Air Force (NAF) to overcome the challenges associated with the existing wired exploders used for the disposal of unserviceable ordnances. The Exploder system has three main parts namely, the master transmitter unit, the master receiver/slave transmitter unit, and the slave receiver unit. Each of these units is made up of transceiver module, microcomputer and power source. The microcomputers were programmed using C and C++ programming language of the Integrated Development Environment (IDE) software. The exploder is portable and easy to operate. For a typical demolition exercise, the operation of the exploder is such that signals are relayed from the master transmitter unit to the master receiver/slave transmitter unit onto the slave receiver unit to initiate an electric detonator leading to the detonation of the unserviceable ordnances. Functionality, range, power consumption, and system reliability tests were conducted on the exploder to establish its performance and efficiency. The results obtained from the tests indicated that the exploder transmitting at a frequency of 2.4GHz performed satisfactorily up to a range of 1000 meters. Therefore, the exploder has the potential of not only meeting the demolition demands of the NAF but can also be applied for other nonmilitary purposes like mining and related activities.

“…Kemudian teknologi fuze bergeser ke chemical based, dan electro-mechanical based [5]- [7] . Untuk electromechanical based, teknologi berkembang mulai dari pengaturan delay detonasi, pengenalan target dan jarak dari target, hingga berbagai metoda trigger untuk primer peledak [5], [8], [9]. Riset mengenai fuze telah dilakukan di Indonesia akan tetapi porsinya sangat sedikit [1].…”

Fuze is a device to ensure the safety, to prepare and to detonate a warhead, with a certain requirements which is set from the design of the mechanism. The design of the fuze requires that the system must be robust so that it will not endangered the handling, transporting and storing the warhead. In addition to that, a fuze must be confirmed that it will trigger the explosion of the warhead when it reaches the target. The sensitive application of the fuze in the military world makes the design mostly confidential and only a little portion is revealed in the media and scientific article. All of this problem contribute to the inability of Indonesia to produce it's own fuze, either the mechanic, chemical or electro-mechanic version of it. All of Indonesian warhead uses imported fuze from overseas, which makes Indonesian military depends on other countries. In this study, prototype of a robust detonator system for a proximity fuze, a type of electro-mechanic fuze that uses a range-sensor to determine the detonation time of the warhead, is made. The system was made using an SF30C Laser as the proximity sensor and a detonation system utilizing an electric signal. The Printed Circuit Board (PCB) was custom built with the majority of components using the Surface Mount Devices (SMD) design style, a Lithium Polymer type battery with a voltage of 7.4 VDC was used as the power supply. The Arduino Pro-Micro was used to be the processor, which was placed on the PCB using a Pin Through Hole (PTH) system. Several configurations have been tested and documented.The detonation system using double-PhotoMOS was proved to be the most reliable compared to several other systems. PhotoMOS was configured so that when it was activated, Proximity Fuze would be able to send an electric current to the detonator, so that the detonator will be burt. The results of experiments shows that the Photomos can trigger detonator explosions at an average error target distance of 1,15%. Thus the Proximiti fuze prototype can be said to work well and is possible to be applied in the defense industry.
