A shot blasting machine is a cleaning machine for casting products with a steel ball shooting mechanism from the impeller/blast wheel rotation's centrifugal force. As the main machine in the final process of casting production activities, the decrease in machine reliability has a negative impact on the production system. Currently, the production equipment maintenance strategy at PT ABC is still implementing corrective maintenance, which is unplanned and reactive when a machine malfunction occurs. It resulted in high production loss and increased maintenance costs. Therefore, the shot blasting machine's maintenance strategy should be changed to a type of preventive maintenance. This study aims to plan preventive maintenance (PM) system for the shot blasting machines of PT. ABC, such as creating PM schedule, calculating machine downtime, and technician needs for each PM activity. PM system planning is achieved using the ISMO (Inspection, Small repair, Medium repair, and Overhaul) method. Its method was conducted in several stages, which start with identifying machine objects, making PM work specifications, determining the value of mark complexity and maintenance cycle, calculating machine downtime and technician needs. Then making schedules annual and monthly, and several other maintenance documents. The mechanism for determining the complexity value is determined based on the similarity of the HP Garg methodology's machine specifications. Finally, The planning of the shot blasting machine PM system has been successfully done, some of the PM information obtained are (i) the machine maintenance cycle is C - I1 - I2 - S1 - I3 - I4 - M1 - I5 - I6 - S2 - I7 - I8 - M2 - I9 - I10 - S3 - I11 - I12 - C, (ii) the time interval between maintenance activities is one month, (iii) machine downtime for each shot blasting machine, (iV) the number and level of maintenance technicians required in every ISMO activity for drum shot, batch shot and hanger shot machines. The calculating verification of the shot blasting machine's availability value on the proposed PM schedule shows that machine availability increased to more than 80%.

The implementation of Quick Response (QR) Code to share or store information increased widely. QR code can quickly provide a data or information such as contact person, plain text, URLs or other data by scan a QR code using smartphone camera. The raised of QR code implementation must to be follow by a level of data security. In this journal we will discuss a number of processes that can be used to improve data security in QR codes. In computer science there are several terms related to data protection i.e. Cryptography and Steganography. Cryptography focuses on securing information in the data exchange process. Steganography is a process of hiding information into an object that cannot be detected by anyone without a steganographic key. With these two processes i.e. cryptography and steganography or a combination of both, the data embedded in the QR code will not be easy to translate. The method that will be discussed is Speck Algorithm encryption and Advanced Encryption Standard (AES) with a combination of Steganography. Both methods succeed in converting confidential information into data that is not easily recognized. Confidential information that goes through a steganographic process becomes difficult to detect and gives the wrong message to a third party.

This paper discusses the failure that occurred on the right front drive shaft of a vehicle with the specification of S45C medium carbon steel material. The right front drive shaft receives several dynamic loads and torque so it must be strong to endure stress [1]. The right front drive shaft shows that there is an initial crack which causes the brittle fracture overload and is caused by sudden external loads. The purpose of this study is to determine the factors causing the failure and to provide a solution if a similar case occurs in components with the same material. Keywords: Front drive shaft right car, carbon steel medium S45C, brittle fracture over load, sudden impact load.
