Judul: Implementation of PDCA (Plan, Do, Check, Action) Cycle to Reduce the Weight Loss of Spicy Wing Product at PT XYZ
Abstrak: PDCA (Plan, Do, Check, Action) adalah metode yang umum digunakan oleh perusahaan untuk mengidentifikasi permasalahan dan penyebabnya. Penelitian secara formal mengenai weight loss saat proses produksi dengan sampel yang besar dan proses berkesinambungan di industri pengolahan daging ayam spicy wing belum pernah dilakukan. Penelitian ini bertujuan mengkaji weight loss saat proses produksi, menganalisis faktor penyebab weight loss, dan membuat standard kombinasi proses yang paling optimal dalam produksi spicy wing di PT XYZ. Penelitian dilakukan dengan tahap Plan (identifikasi masalah, spesifikasi masalah, dan pengumpulan data), tahap Do (analisis data, pembuatan kesimpulan tentatif, dan pemeriksaan kesimpulan statistik), tahap Check (melakukan percobaan), dan tahap Action (melakukan tindakan perbaikan dan mempertahankan hasil perbaikan). Penentuan faktor penyebab weight loss dilakukan dengan metode PDCA dan dibantu dengan teknik GKM (Gugus Kendali Mutu) yang berisikan manajer, supervisor, dan leader pada masing-masing divisi. Hasil penelitian menunjukkan perlakuan pembekuan dengan Individual Quick Freezing (IQF) pada sampel middle wing dan wing stick dapat menurunkan thawing loss menjadi 0,68±0,19% dibandingkan perlakuan Blast Freezer (BF) dengan thawing loss sebesar 2,84±0,39%. Metode IQF ini juga menghasilkan saving cost sebesar Rp 1.195.200,-/Order Kerja Produksi (OKP). Kata kunci: freezing, GKM, PDCA, spicy wing, weight loss., PDCA (Plan, Do, Check, Action) is a method commonly used in company to identify problems and it causes, to conduct the improving and controlling as well as to maintain the produced product quality. Formal the research topic about weight loss in production line with a large sample and continuous process in the chicken meat (spicy wing) processing industry has never been done. This research aimed to study weight loss in line production, to analyze the factors behind weight loss and create the most optimal process combination standard in the production of spicy wings at PT XYZ. The research was carried out with 4 stages. Plan (problem identification, problem specification and data collection), Do (data analysis, formulation of provisional conclusions and verification of statistical conclusions), Check (realization experiences), and Action (take corrective action and maintain improvement results). The determination of the factors that caused weight loss was done using PDCA method and supported by Quality Control Group (QCG) technique involving managers, supervisors, and leaders of each division. The results showed that freeze treatment with Individual Quick Freezing (IQF) on samples middle wing and wing stick was able to reduce thaw loss to 0.68±0.19% than the freez treatment with Blast Freezing (BF) with thaw loss 2.84±0.39%. IQF method was able to gain saving cost Rp 1.195.200,-/Production Work Order (PWO). Keywords: freezing, PDCA, spicy wing, QCG, weight loss.

Judul: Aplikasi Siklus PDCA (Plan, Do, Check, Action) Dalam Upaya Menurunkan WIP (Work In Process) Produk Chicken Nugget di PT. Belfoods Indonesia
Abstrak: Chicken nugget is the main product that produced by PT. Belfoods Indonesia. The purpose of this research internship is reducing the amount of WIP (Work In Process) of chicken nuggets A which has size 250 grams during the production process. Chicken nugget production process has several stages. Packaging stage is the stage that determines the amount of WIP product. Working methods to implement PDCA cycle (Plan, Do, Check, Action). The analysis showed that there were four factors that influence the amount of WIP products, the amount of spade and design didn’t fit, unstructured product after filling, the difference determination officers to tidy packaging, and packaging decoding after exit IQF products. Work plan was prepared by providing employee training and submission of the purchase and design of a new tool. The results of the second times from repairing process after conducting employee training even without the use of alternative tools (shovel) was quite successfully. Control measures had been done by drafting some work rules and division of labor during packaging
