Abstract

Milk pie cake is the most popular product in MSME Queen Pie, but the number of orders is directly proportional to the resulting defect. Statistical Quality Control (SQC) and Failure Mode and Effect Analysis (FMEA) methods are used to optimize this. In the study there are defects in milk pie cake is charred, immature, broken, bubbling and sticky. In the check sheet, the average defect per month is 8.6%. Furthermore, the flowchart in the production process consists of 3 parts, namely raw material handling, production and packaging. From the results of the Scatter Diagram shows that between production variables and defects are interconnected. Then on the histogram, the biggest defect is the rupture product with defect 844. In pareto seen dominant defect type rupture by 34.7%. Furthermore, the attribute map contains data out of control in February. The results of fishbone diagram analysis of the causes of defect factors are human, machine, method, material and environment. Based on the analysis of FMEA further improvement proposals are made that perform regular maintenance, give workers adequate rest periods, check the temperature of the oven periodically, more thorough in choosing flour with good quality and ensure the mold has been smeared with margarine before given the dough.

Abstract

UMKM Chellbie merupakan industri rumahan yang bergerak di bidang produksi sandal kulit dengan skala menengah. Dalam proses produksinya, perusahaan sering menghadapi masalah kecacatan produk (defect) yang melebihi batas toleransi maksimal sebesar 5%, sehingga berdampak pada penurunan efisiensi, peningkatan biaya produksi, dan penurunan kepuasan pelanggan. Penelitian ini bertujuan untuk menganalisis dan mengendalikan jenis-jenis kecacatan produk sandal kulit dengan menerapkan metode Failure Mode and Effect Analysis (FMEA) dan Root Cause Analysis (RCA). Metode FMEA digunakan untuk mengidentifikasi mode kegagalan dan menghitung nilai Risk Priority Number (RPN) berdasarkan tiga parameter utama: Severity (S), Occurrence (O), dan Detection (D). Sementara itu, metode RCA digunakan untuk menelusuri akar penyebab dari jenis kegagalan dengan pendekatan 5 Whys dan diagram tulang ikan (fishbone diagram). Data yang digunakan diperoleh dari produksi bulan Juni hingga Desember 2024. Hasil analisis menunjukkan bahwa jenis defect yang paling dominan meliputi: aksesoris sandal rusak, sisa lem meluber di sisi sandal, katoan tidak melekat, sablon meluber, dan upper yang tidak melekat sempurna dengan sol. Nilai RPN tertinggi ditemukan pada faktor material dan manusia, dengan nilai mencapai 900. Berdasarkan RCA, penyebab utama dari kegagalan tersebut berasal dari rendahnya kualitas bahan baku, tidak digunakannya SOP, serta kurangnya pelatihan operator. Penelitian ini menghasilkan rekomendasi perbaikan berupa penerapan SOP secara konsisten, pengawasan terhadap bahan baku dan supplier, perawatan mesin secara berkala, serta pengendalian lingkungan kerja. Implementasi metode FMEA dan RCA secara terpadu terbukti mampu menurunkan potensi defect dan meningkatkan mutu produk sandal kulit di UMKM Chellbie.
