<p>The submission of job orders for repairs, new machine installations, modifications, and machine relocations is currently done manually using paper. This manual process causes delays in job order delivery, difficulties in monitoring the progress of job orders, and challenges in finding and archiving job order forms. To address these issues, this study designed a web-based e-JO system using the CodeIgniter framework and MySQL database. The system aims to make the process more efficient and structured. After implementing the e-JO system, data was collected to measure potential time savings. The results showed that before the change, the job order submission process took 17,287 seconds, whereas after the new system was implemented, it only took 1,137 seconds. Thus, it can be concluded that the e-JO system significantly reduced the job order submission time, making the process faster and more efficient.</p>Diva Herna AuroraM. Ridwan Arif Cahyono

https://jurnal.poltek-gt.ac.id/index.php/jiti/article/view/86
<p>PT AWW operates several plants, one of which is a mixing plant that produces compounds. The mixing plant produces two types of compounds: master-batch compounds and final-batch compounds. Master-batch compounds are not allowed to undergo the metal detector process. In contrast, final-batch compounds are reprocessed master-batch compounds with the addition of final-batch powder, making them suitable for the Metal Detector process. The processed final-batch compounds pass through the metal detector machine for foreign material detection. However, a problem was identified during the process: operators are required to manually mark compounds with foreign material, resulting in loss time. This loss time occurs when the machine detects foreign material in the compounds, and operators need time to mark the detected compounds. Therefore, a marking tool was developed to facilitate operators in marking compounds detected with foreign material. Design and construct wiring and programming for a control system utilizing a stepper motor as the actuator for a marking tool based on Arduino Mega and TB6600 driver, resulting in a semi-automated tool. This eliminates the need for manual marking and replaces it with a one-button operation marking device..</p>Rosyidin JibrilAdik Susilo Wardoyo

https://jurnal.poltek-gt.ac.id/index.php/jiti/article/view/87
<p>At PT XYZ, the Bias cutting process plays a crucial role in tire production, particularly in the handling of<br />Treatment rolls involving the Air Brake Roll Treatment system. Currently, pressure adjustment on the Bias cutting machine at the Let Off section is performed manually by operators, often leading to inaccuracies in pressure reduction. These inaccuracies result in uneven compression of the Treatment rolls, leading to increased scrap rates and reduced production efficiency. This study aims to modify the pressure system by replacing the manual method with an automated system using the IFM O1D100 Distance Sensor. This modification involves automatically adjusting pressure based on the distance of the Treatment roll, thereby reducing the risk of unwanted compression and enhancing the consistency of the Bias cutting process. The study results show that using an electro-pneumatic system controlled by the Distance Sensor allows for more precise pressure adjustment, contributing to reduced scrap rates and improved production efficiency.</p>Muhamad Kahlil FirdausiRahmat WidiantoroMuhammad Ibnu Rusydi

https://jurnal.poltek-gt.ac.id/index.php/jiti/article/view/88
<p>PT. XYZ, a motorcycle tire factory, encountered a malfunction in the ITL.01.TL.01 cutting machine due to an overheating heating system. This research aims to modify the heating system on the ITL.01.TL.01 machine used for cutting inner liners. Manual cutting caused variations in inner liner length (73-78 meters), impacting production efficiency and consistency. The improvement method involved modifying the heater control system. Data were obtained through direct observation and analyzed using descriptive statistics. The modification, including the addition of a thermocouple sensor for real-time temperature monitoring, improved accuracy and efficiency in temperature control. Power calculations showed that the modified system operated with better energy efficiency. Paired T-test analysis indicated a significant performance improvement after the modification. These modifications allowed the cutting machine to operate, reducing material length variation and increasing overall<br />efficiency.</p>Wahyu Pebriansyah AsmaraPaul Michael SiahaanDharmanto

https://jurnal.poltek-gt.ac.id/index.php/jiti/article/view/82
<p>This research discusses monitoring the flow rate used as a cooling medium for a cold runner type curing machine which is equipped with a flow sensor and integrated with an Omron PLC and HMI TS1100 to increase production results in the IMD-50 curing machine. This system is designed to monitor and control coolant flow accurately, so as to maintain product quality. Tests were carried out using the Wilcoxon test method to analyze NG data before and after implementing the modification to add the SM7000 IFM floe sensor, to ensure a significant increase in production efficiency and quality. The research results show that the use of the IFM SM7000 floe sensor on a 2000 cc cold runner curing machine and the integration of the Omron PLC and HMI TS1100 significantly improves process control and reduces torn and short mold NG products. In addition, payback period analysis shows that investments in this system can be returned in a relatively short time, making it an economical and<br />effective solution for the manufacturing industry. Thus, the implementation of this technology not only provides technical benefits but also significant financial benefits for companies.</p>Yogi Tama Muhammad ArdiyansyahAri Kuswantori

2025-05-262025-05-2662172182Rancang Bangun Sistem Kontrol Elektro Pneumatik Pada Alat Bantu Pemotong Green stick tube
https://jurnal.poltek-gt.ac.id/index.php/jiti/article/view/94
<p>The current process for cutting green stick tubes at the company is still done manually by operators using scissors because the extruder machine cannot cut sizes below 1,000 mm. As a result, sizes 6.00-9 and 6.50-10 must be cut manually before the splicing process. The green stick tubes coming out of the extruder often exceed the splicing machine’s cutting tolerance of 20 mm. According to the data, sizes 6.00-9 and 6.50-10 with a length of 1010 mm need to be cut to 840 mm and 910 mm, respectively. The average cutting time per shift is 164.6 seconds, influenced by the time operators take to find scissors and the lack of efficient cutting tools. The main issues in this cutting process are caused by three factors: Machine, Material, and Man. The extruder machine cannot cut green stick tubes smaller than 1,000 mm. The green stick tube material of sizes 6.00-9 and 6.50-10 needs to be cut because their length exceeds the requirement. Additionally, inconsistencies among operators when cutting occur due to the lack of proper tools or guides. To address these issues, a cutting aid tool using a heater and pneumatic system is designed. This tool is expected to facilitate the cutting process of green stick tubes. The design of this tool aims to overcome the extruder machine’s inability to cut smaller sizes, reduce unnecessary additional time, ease the cutting process for operators, decrease the variation in cutting time, and improve the workflow in the splicing section, so the green stick tubes can be processed directly without additional hindrances.</p>Syifa Amalia Azzahra Putri WardoyoHenry Prasetyo
