Abstract

Abstract In the machining process, there are three parameters that need to be determined before the machining process is carried out, namely: depth of cut (a), feed motion (f) and cutting speed (v). Determination of the three parameters of the machining process will determine the quality of the product to match the desired geometry and tolerance. The three parameters of the machining process will affect tool life, where the selection of a constant depth of cut and feed motion will produce the most optimum level of tool wear. This study used several machining parameters with several variations, namely: depth of cut (a) of 0.5 mm; 0.8mm; 1.1mm; and 1.4 mm and feeding motion (f) of 0.062 mm/revolution and 0.1 mm/revolution. The machining process is carried out at a constant (n) rotation of 425 rpm. Based on the research that has been done, it was found that the tool life on the feed motion (f) = 0.062 mm/revolution is better than that on the feed motion (f) = 0.1 mm/revolution, where at (f) = 0.1 mm/revolution chisel wears out faster. Optimum cutting conditions are produced at feed motion (f) = 0.062 mm/revolution and with a depth of cut (a) = 1.1 mm where the production cost (Cp) is Rp.746.56/product.

Abstract

The importance of accurate, real-time intelligence in modern warfare is crucial, especially in reconnaissance and surveillance operations. Currently, drones are widely used for reconnaissance, but generally rely only on the operator's ability to monitor operation targets. This research is aimed at developing an AI vision assistance system to enhance the ability to detect military vehicles and infantry. The method used is computer vision trained to recognize and differentiate several military objects. The YOLO model is used to detect and distinguish objects. To improve detection capabilities, the YOLO v8 model was retrained with an additional dataset sourced from battle recordings on the battlefield. The results show a detection accuracy rate of 95% in detecting vehicles and infantry under normal visual conditions. The model from this research can be used to enhance the capabilities of reconnaissance drones and the effectiveness of monitoring operations.

Abstract

Biomaterials is an advanced material engineering technology that is used to help heal bone fractures or fractures. Currently, many biomaterials use materials such as titanium alloy, stainless steel, platinum, and chromium, but these materials cannot be degraded naturally so a second operation must be carried out to remove the installed biomaterial. Biomaterials are temporary in nature so when the bone returns to its original state, the biomaterial must be surgically removed. Research was conducted to obtain a design with a material that can be naturally degraded without causing toxicity. Magnesium AZ31B is a recommended candidate as a base material for degradable bone implants. Magnesium AZ31B material, it is expected to reduce or minimize the surgical removal of implant biomaterials. Bone plate geometry use plate bone dimension 150mm x 15mm x 3mm with variation 10 hole parallel and zigzag as well as with a bolt bone dimensions long 40 mm with pitch 1mm diameter 5mm. Test bending was conducted with ASTM E290-14 showing that on plate bone hole parallel with burden maximum 33,419 KN with a deformation maximum of 30.89 mm whereas for plate bone hole zig zag with the burden maximum 32,863 KN with deformation maximum big as 29.97 mm. From the study experimental that plate bone hole parallel have nature mechanic more tall compared with plate bone hole zig Zag although with the difference which is not significant. Whereas on simulation FEA plate bone hole parallel with burden 33,419 KN get results total deformation as big as 31,481 mm with von Mises stress 15,337 MPa, then for plate bone hole zig Zag with burden 32,863 KN with total deformation 32.466 mm and von Mises stress as big as 33,948 MPa. In testing by experiment and simulation FEA plate bone hole parallel get difference around 0.591 mm or 0.94% whereas for plate bone hole zig Zag in testing by experiment and simulation get difference around 2,893 mm or 4.60%.

Abstract

This research aims to design and create a sms-based motor vehicle security system with an ATMega 8535 microcontroller. This research utilizes hand phone technology and microcontroller. Making this tool has an economical price to secure motorized vehicles. Important prototypes in making this tool are the ATMega 8535 microcontroller, GSM Modem and HP. In making this tool the first thing to make is to make a microcontroller program for the controller. Making this program uses CV Avr soft ware (Code Vision Avr). After the program is finished, the program is downloaded to the microcontroller. Control is done by the microcontroller when it gets input. The result of this research is to get a vehicle security system that is integrated by the ignition system on a motorcycle. The process of securing a motorized vehicle when it is stolen is, the security system will send sms information that the motorcycle is stolen, the alarm sounds and the ignition system is cut off. To turn off the alarm and start the motorcycle, the owner sends an SMS with the format *ALOF# to the security system and starts the motorcycle normally (Pull the front brake three times then position the key to ON mode).
