CV.XYZ is a company that produces footwear. From December 2022 – February 2023, the BS-12 footwear model experienced many product rejects. The high percentage of rejected products raises quality costs for rework activities. Identification of the type of rejection and the rework process is needed to determine the rework costs incurred by the company. Analysis of quality costs due to the rework process was carried out using the Process Costing method while identifying the factors causing the occurrence of rejected products using Why-why Analysis. The results of the analysis showed that there were 6 types of damage, namely straps (mouldy, abrasions, broken seams), insole (mouldy, abrasions, broken seams), excess glue, less sticky insole and outsole, loose straps & slippery sole. The quality costs incurred by the company during December 2022 – February 2023 amount to IDR 16,250,104. Products were rejected for multiple reasons, including inadequate facilities and equipment, operators working from home, and a staff shortage to meet production demands. Proposed improvements using 5W+1H included rearranging the production layout for strap storage, making SOP and WI for operators who work at home, buying press machines, and increasing the number of operators.

PT XYZ is a manufacturing company that produces clay roof tiles with one of the raw materials is Carboxymethyl Cellulose (CMC) for the glazing process. Currently, CMC inventory management faces a problem where during January-December 2023 there was an average overstock of 2,467 kg/month or Rp225,241,200/month. In order to minimize overstock and reduce inventory costs, it is necessary to analyze CMC inventory planning. Inventory analysis begins with forecasting to determine CMC requirements for the January-December 2024 period. The inventory planning methods used were Economic Order Quantity (EOQ) and Economic Order Interval (EOI). The selected forecasting method was Double Moving Average because it has the smallest forecasting error with a MAPE of 10.86% and valid MR Chart verification. The results of the analysis of total inventory costs during the period January-December 2024 using the EOQ method amounted to Rp2,139,459,931 while the EOI method amounted to Rp2,139,739,357. Based on the cost difference between the two methods, it is proven that the EOQ method is cheaper than the EOI method, and the results of the cost comparison analysis using the method used by the company is proven that if the company uses the EOQ inventory method the company will be able to save Rp7,042,779 or 0.33% per year. Thus the EOQ method is the right method in minimizing the total cost of CMC inventory and can minimize the risk of overstock.

PT. XYZ is a manufacturing company that produces ceramic roof tiles. A good tile specification is if the clay as raw material has a wetness level after the drying process ?2.5%. The level of clay wetness affects the quality of the product. If the level of wetness after the drying process does not meet the specifications, the product will break easily. Currently, the average initial wetness level of clay (before the drying process) is 18%-22%. This research aims to determine the right time setting in the ceramic tile drying process to produce a wetness level after drying according to specifications by conducting an experimental study at the Company's Laboratory. Experiments were conducted on five clay samples with initial wetness levels of 18.60%; 19.87%; 20.45%; 21.42%; and 22.03%. Each sample was dried for 30, 40, 50, 60, and 70 minutes to produce post-drying wettability according to specifications. The experimental results were processed by Two-Way ANOVA without interaction to evaluate the effect of initial wetness level and drying duration on clay wetness level after drying process. The analysis resulted in clay drying duration for initial wetness of 18.60% at least 40 minutes, initial wetness of 19.87% at least 50 minutes, initial wetness of 20.45% and 21.42% at least 60 minutes, and initial wetness of 22.03% at least 70 minutes with a temperature of 180°C, resulting in clay wetness after drying according to specifications. Based on these findings, an SOP for checking the initial wetness of clay for the drying process was developed to produce good quality roof tiles. PT. XYZ merupakan perusahaan manufaktur yang memproduksi genteng keramik. Spesifikasi genteng yang baik adalah jika clay sebagai bahan baku memiliki tingkat kebasahan setelah proses pengeringan ?2,5%. Tingkat kebasahan clay berpengaruh terhadap mutu produk. Jika tingkat kebasahan setelah proses pengeringan tidak sesuai spesifikasi, akan berakibat pada produk mudah pecah. Saat ini, rata-rata tingkat kebasahan awal clay (sebelum proses pengeringan) adalah 18%-22%. Penelitian ini bertujuan untuk menentukan pengaturan waktu yang tepat pada proses pengeringan genteng keramik untuk menghasilkan tingkat kebasahan clay setelah proses pengeringan sesuai spesifikasi dengan melakukan studi eksperimen di laboratorium PT. XYZ serta menyusun SOP pengecekan kebasahan awal clay. Eksperimen dilakukan terhadap lima sampel clay dengan tingkat kebasahan awal 18,60%; 19,87%; 20,45%; 21,42%; dan 22,03%. Masing-masing sampel dikeringkan selama 30, 40, 50, 60, dan 70 menit hingga menghasilkan tingkat kebasahan clay setelah proses pengeringan sesuai spesifikasi. Hasil eksperimen diolah dengan Two-Way ANOVA tanpa interaksi untuk mengevaluasi pengaruh tingkat kebasahan awal clay dan durasi pengeringan terhadap tingkat kebasahan clay setelah proses pengeringan. Hasil analisis menghasilkan durasi pengeringan clay untuk kebasahan awal 18,60% selama 40 menit, kebasahan awal 19,87% selama 50 menit, kebasahan awal 20,45% dan 21,42% selama 60 menit, dan kebasahan awal 22,03% selama 70 menit dengan suhu 180°C sehingga menghasilkan tingkat kebasahan clay setelah proses pengeringan sesuai spesifikasi. Berdasarkan temuan ini, disusun SOP pengecekan kebasahan awal clay untuk proses pengeringan agar menghasilkan kualitas genteng yang baik.
