Ketidaksesuaian kualitas pada proses assembly sepatu kulit kerap memicu siklus rework berulang yang menguras sumber daya waktu maupun biaya produksi secara signifikan. Penelitian ini mengkaji mekanisme pengendalian cacat yang diterapkan pada Product D-01 di Lini C PT XYZ, dengan menggunakan DMAIC sebagai kerangka perbaikan utama serta Pareto, P-Chart, Fishbone Diagram, 5 Whys, Failure Mode and Effects Analysis (FMEA), dan Cost of Quality (COQ) sebagai alat pendukung. Data primer bersumber dari catatan produksi internal perusahaan, pengamatan lapangan, dan wawancara terstruktur bersama pengawas produksi dan staf quality control. Pengukuran baseline menunjukkan bahwa Lini C menyumbang volume cacat paling tinggi di antara seluruh lini yang ada, dengan Product D-01 mencatat 10.487 pair cacat dari total output 80.387 pair, sehingga menghasilkan defect rate sebesar 13,05%. Distribusi Pareto mengidentifikasi wrinkle, incorrect colour, dan not straight sebagai tiga kategori cacat paling kritis. Penilaian FMEA menetapkan Risk Priority Number tertinggi sebesar 245 pada perilaku operator yang terburu-buru selama proses lasting dan brushing. Tindakan korektif mencakup pemasangan SOP visual, implementasi checklist QC pra-shift, verifikasi kondisi mesin secara rutin, dan penyediaan sampel referensi warna serta bentuk yang terstandar. Pemantauan selama dua periode berikutnya mengkonfirmasi penurunan defect rate secara bertahap menjadi 12,80% dan kemudian 11,65%, disertai penurunan estimasi biaya kegagalan internal dari Rp 2,36 juta menjadi Rp 1,86 juta per periode.

This study designs and implements an up-down counter system based on an AT89C2051 microcontroller programmed in assembly using the MC-51 application. The system modifies an existing digital clock board by mapping the display selector pins, seven-segment segment pins, pushbuttons, and buzzer to the microcontroller ports. The research method consists of literature review, hardware identification, algorithm design, assembly programming, program downloading, and functional testing using a 5 V DC supply. The implementation uses a four-digit common-cathode seven-segment display and a multiplexing routine to show the counter value in real time. The functional test shows that the system can display the initial value, increase the value through the up button, and decrease the value through the down button. The display is readable during operation, and the program can run on the target circuit after being downloaded to the AT89C2051. This study confirms that assembly programming on MC-51 can be applied to implement a simple counter system on a reused digital clock circuit. The main limitations are the absence of explicit button debouncing, overflow and underflow protection, quantitative response-time measurement, and non-volatile data retention.
