Analisis Perbedaan Pembacaan Kalibrator Temperatur dengan Drywell Menggunakan Uji Wilcoxon
The oven calibration process is a crucial step in ensuring the accuracy of temperature testing on tire components. At the PT XYZ DKM Plant, oven calibration is still performed externally due to the lack of a nine-point temperature calibrator compliant with AS 2853. This impacts calibration time and costs. Therefore, this study aims to design and analyze the performance of a nine-point temperature calibrator compared to the AIS-TCL-3 master temperature calibrator. The test was conducted at a temperature range of 30°C to 150°C with a minimum of 30 data points per point. The results were then analyzed using normality tests, Wilcoxon test, and Cohen's d test. The Wilcoxon test results showed no statistically significant differences between the designed instrument and the master instrument. Furthermore, all measurement values were within the ±1°C tolerance limit as per ASTM D1509-15 standard. This is supported by the Cohen's d value, which indicates a low to moderate difference in effect. Thus, the designed calibrator tool is declared suitable for use in internal calibration processes and can be an economical solution for the company.
Modifikasi Sistem Counter Length Tread Pada Mesin Building PT ASD
The positioning system for the photocell on the PT ASD tire building machine's tread counter length is still manually operated and relies on the operator's intuition. The operator needs several attempts to adjust the photocell's position to produce tread cuts that meet specifications.

Rancang Bangun Sistem Kontrol Elektro Pneumatik Pada Alat Bantu Pemotong Green stick tube
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.
