“…Titik data tersebut masih berada dalam batas kendali dikarenakan jumlah rejectnya masih berada di antara nilai UCL dan LCL. Sedangkan titik data yang melewati nilai LCL memiliki jumlah reject yang kurang dari 6,58 hal ini menunjukkan bahwa reject belum terkendali secara maksimal (Idris et al, 2021). Selama titik-titik data tersebut terdapat dalam batas-batas pengendali, proses dianggap terkendali dan tidak perlu adanya tindakan tertentu.…”

Statistical Process Control (SPC) is a process used to monitor standards, make measurements, and take corrective action on products or services being produced. This research aims to determine the factors that cause damage to the packaging of ground coffee products at CV. Dewi Starindo and applying the SPC method to reduce the number of packaging rejects along with improvements. This research method uses Statistical Process Control (SPC) to determine whether the packaging quality is within control limits or not. Data analysis uses p control charts (p-chart), Pareto diagram, fishbone chart. The data used is the number of rejected products and packaging from July to September 2023. The research results show that the types of defects found in product packaging are slanted labels, open seals, inappropriate weight and holes. 5 data are outside the control limits and 3 data are within the control limits. The Pareto diagram shows that the largest reject rate is from unsuitable heavy reject types, 55.56%, and the smallest for perforated packaging, 1.94%. As for fishbone chart, the main factors causing rejects come from humans, materials, and machines. After improvements were made with suggestions in the form of providing direction and training, installing written SOPs, carrying out calibration and maintenance on machines, and checking the materials used, the Pareto diagram showed that there was a decrease in the number of rejects, from 55.56% to 47.76%. It shows that there is no more data that is outside the control limits. Keywords: Statistical Process Control (SPC), p control chart (p-chart), pareto diagram, fishbone chart Statistical Process Control (SPC) merupakan proses yang digunakan untuk mengawasi standar, membuat pengukuran dan mengambil tindakan perbaikan pada produk atau jasa yang sedang diproduksi. Penelitian ini bertujuan untuk mengetahui faktor-faktor penyebab kerusakan kemasan produk kopi bubuk di CV. Dewi Starindo dan menerapkan metode SPC dalam mengurangi jumlah reject kemasan beserta usulan perbaikannya. Metode penelitian ini menggunakan Statistical Process Control (SPC) guna mengetahui kualitas kemasan dalam batas kendali atau tidak. Analisis data menggunakan peta kendali p (p-chart), diagram pareto, fishbone chart. Data yang digunakan, yaitu jumlah produk dan kemasan reject pada bulan Juli hingga September 2023. Hasil penelitian menunjukkan bahwa jenis cacat yang terdapat pada kemasan produk kopi bubuk Nusantara adalah label yang miring, segel terbuka, berat yang tidak sesuai dan berlubang. 5 data yang berada di luar batas kendali dan 3 data di dalam batas kendali. Diagram pareto menunjukkan bahwa tingkat reject terbesar adalah pada jenis reject berat yang tidak sesuai, yaitu sebesar 55,56% dan terkecil pada kemasan berlubang, yaitu 1,94%. Adapun pada fishbone chart diketahui faktor utama penyebab reject berasal dari manusia dan mesin. Setelah dilakukan perbaikan dengan saran berupa memberikan arahan dan pelatihan, memasang SOP tertulis, melakukan kalibrasi dan pemeliharaan pada mesin, dan memeriksa bahan yang digunakan, diagram pareto menunjukkan bahwa terjadi penurunan jumlah reject, dari 55,56% menjadi 47.76%. Setelah dihitung kembali menunjukkan bahwa tidak ada lagi data yang berada di luar batas kendali.

Towards Digital Transformation of the Validation and Triage Process of Textbooks in the Brazilian Educational Policy

et al. 2023

One factor that impacts the quality of Brazilian education is the quality of books and other didactic materials freely distributed throughout the country to public schools, thanks to the Brazilian National Textbook Program. The current evaluation process may take at least two years to complete, involving hundreds of people, and the final result may impact the entire educational system. One of the first activities of the process is to validate and triage the editorial quality attributes of textbooks. However, the validation and triage process needs improvement, considering the gradual expansion of the quantity and variety of materials that currently affect it. This generates risks of reduced quality and timely deliveries. This paper provides a comprehensive critical analysis of the validation and triage process based on the Policy Design Arc framework of Harvard’s Kennedy School of Government. We identified causes that affect the quality of deliveries and the time required to conclude tasks. We also propose a theory of change for digital transformation, defining strategies to address the causes of problems, outputs, outcomes, and impacts. Therefore, we have gradually implemented our theory of change in the validation and triage process.

“…[25,26] The value of Z1 in simplex optimization provides a solution for optimizing the farmers' profit by an average price. [27,28,29] The value of Z2 in simplex optimization provides a production solution based on the average amount of consumption. In this case, Pareto makes a representative solution philosophy in deciding production and optimization criteria Z1 and Z2 for medium-quality and super-quality rice in the form of graphs.…”

Indonesian agricultural production is unpredictable. The harvest quality causes this is not-optimal harvest quality. The researchers provide a solution by utilizing a severe game design model as a learning medium to make decisions for optimizing production. In comparison, Blockchain technology is for data security, Distributed ledgers and Smart Contracts. The transaction between producers and consumers are permanent and verified. For the literature study of optimization to maximize farmers' production, the researchers use Simplex Method as an objective function and the Pareto function as an optimization model for multiple problems by finding solutions for all purposes to improve farmers' production. Multi-Objective Optimization, Linear Programming, Blockchain, and Hierarchical State Finite Machine are needed to design a serious game. This study designed Hierarchical State Finite Machine Serious Game using Blockchain and Multi-Objective Optimization method as a learning medium to simulate farmers making decisions In producing agricultural quantities based on consumer demand, stock, price, season, and planting time. Blockchain is used to track the availability of farm stocks so that the supply of consumer needs is met.
