Abstract

Rejects represent a major quality issue in the production process. If not effectively mitigated, they can increase production costs, disrupt process flow, and reduce customer satisfaction. This study aimed to minimize product rejection in rubber clutch damper manufacturing by applying the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) methodology. In the Define phase, Critical to Quality (CTQ) characteristics were identified to determine key improvement priorities. The Measure phase involved data collection to calculate Defects per Million Opportunities (DPMO), sigma level, and the construction of a Pareto chart to highlight the dominant sources of defects. Subsequently, the Analyze phase employed Failure Mode and Effects Analysis (FMEA) to evaluate the Severity, Occurrence, and Detection of potential failures, leading to the determination of the Risk Priority Number (RPN) as a basis for improvement prioritization. In the Improve phase, corrective actions targeting the highest RPN factors were implemented, followed by the Control phase, which established sustainability through One Point Lessons and Standard Operating Procedures (SOPs). The implementation of the DMAIC framework resulted in a substantial improvement in process capability, indicated by an increase in sigma level from 4.11 to 4.58, and a reduction in the total production rejection rate from 1.51% to 0.31%. A paired t-test confirmed a statistically significant difference between pre- and post-improvement rejection rates (t = 61.63, p < 0.0001), leading to the rejection of the null hypothesis. These findings demonstrate that the applied improvements effectively reduced product defects and achieved a total rejection rate below the company’s management target of 0.40%. The study confirms the effectiveness of the DMAIC approach in enhancing product quality and operational efficiency within rubber component manufacturing. Bahasa Indonesia Abstract: Permasalahan reject merupakan salah satu isu krusial dalam proses produksi yang apabila tidak segera ditangani, dapat berdampak pada peningkatan biaya produksi, keterlambatan pengiriman antarproses, serta penurunan tingkat kepuasan pelanggan. Penelitian ini bertujuan untuk menurunkan tingkat reject pada produk rubber clutch damper melalui penerapan metodologi Six Sigma dengan pendekatan DMAIC (Define, Measure, Analyze, Improve, Control). Pada tahap Define, dilakukan identifikasi Critical to Quality (CTQ) untuk menentukan karakteristik yang berpengaruh signifikan terhadap kualitas produk. Tahap Measure meliputi pengumpulan data produksi guna menghitung nilai Defects Per Million Opportunities (DPMO), tingkat sigma, serta penyusunan diagram Pareto untuk mengidentifikasi jenis cacat dengan kontribusi terbesar terhadap total reject. Selanjutnya, tahap Analyze dilaksanakan menggunakan metode Failure Mode and Effects Analysis (FMEA) dengan penilaian terhadap parameter Severity, Occurrence, dan Detection, yang dikalikan untuk memperoleh nilai Risk Priority Number (RPN) sebagai dasar prioritas tindakan perbaikan. Tahap Improve difokuskan pada penerapan solusi korektif terhadap faktor penyebab dengan nilai RPN tertinggi, sedangkan tahap Control menitikberatkan pada keberlanjutan hasil perbaikan melalui penyusunan One Point Lessons (OPL) dan Standard Operating Procedures (SOP). Penerapan metodologi DMAIC menghasilkan peningkatan kapabilitas proses dengan kenaikan nilai sigma dari 4,11 menjadi 4,58, serta penurunan rejection rate total produksi dari 1,51% menjadi 0,31%. Hasil uji paired t-test menunjukkan perbedaan yang signifikan antara tingkat rejection rate sebelum dan sesudah perbaikan (t = 61,63; p < 0,0001), sehingga hipotesis nol ditolak. Dengan demikian, penerapan DMAIC terbukti efektif dalam menurunkan tingkat reject secara signifikan hingga di bawah target manajemen sebesar 0,40%, sekaligus meningkatkan kualitas produk dan efisiensi proses produksi.

Abstract

Institute of Dharma Keuskupan Agung Jakarta is a community that serves the poor and oppressed in the Jakarta area and beyond. One of the services provided is through the existence of the same Mission to teach residents to be diligent in saving. Currently the manager uses Microsoft Excel to process data 30 groups with 370 cooperative members manually, and this method takes a lot of time and labor. To help solve these problems, a cooperative information system was created that could process data and provide information quickly for cooperative managers using Microsoft Access. The system design is done by the Prototyping method, one of the Systems Development Life Cycle methods, which consists of four stages. The first, the Planning: system requirements are determined and a feasibility study is carried out. The second, the Analysis: functional and non-functional requirements are defined and behavior modeling is carried out. The third, the Design: the interface layer is designed. The fourth, the Implementation: the proposed system program is run and tested. The information system is made capable of receiving financial data input, members, and cooperative groups and then provide information on financial reports, book closing reports, and statistical reports automatically. The application has been tested by the cooperative manager and declared successful in providing information quickly, accurately and easily.Bahasa Indonesia Abstrak: Lembaga Daya Dharma Keuskupan Agung Jakarta merupakan sebuah komunitas yang melayani warga miskin dan tertindas di daerah Jakarta dan sekitarnya.

Abstract

Kalila Ultimate Bantal, a micro, small, and medium enterprise (MSME), faces challenges in balancing production capacity, sales targets, and operational efficiency. This Community Service Program (PkM) aimed to support production planning through the application of the Simplex Method, Sensitivity Analysis, and Goal Programming. Data were collected through observation and interviews regarding production costs, capacity, and sales targets. The Simplex Method identified the minimum-cost production plan, while Sensitivity Analysis evaluated the robustness of the solution. Goal Programming was then applied to accommodate multiple operational objectives simultaneously. The Simplex Method recommended producing 13 pillows for online sales and 400 pillows for offline sales, resulting in a minimum production cost of IDR 7,802,650 per day. Sensitivity Analysis indicated that the solution remained stable under moderate parameter changes. Goal Programming produced a compromise solution of 13 bolsters for online sales and 348 bolsters for offline sales to satisfy cost, capacity, sales, and profit targets. These findings demonstrate the usefulness of quantitative optimization in supporting MSME production planning and decision-making.

Abstract

SAMPAHQU as a waste collection company in Tangerang Selatan plays a crucial role in the circular economy. With the increasing number of customers and collaborating waste banks, the need for a waste deposit application that can be accessed by SampahQu, waste bank administrators, and customers has become evident. This application is intended to facilitate SampahQu in monitoring the volume and types of waste deposited, as well as the corresponding monetary transactions to be paid to customers or waste bank administrators. Additionally, customers and waste bank administrators can access information regarding the types and quantities of waste they have deposited, along with the earnings derived from these deposits. To address these requirements, a web-based waste deposit application has been developed, enabling access via mobile devices. Nonetheless, several issues have been identified during its implementation, such as the lack of a payment reporting feature to the waste bank and the absence of customer-specific reports grouped by waste bank. Consequently, this research focuses on the enhancement of the SampahQu application to improve its utility for waste banks and SampahQu customers.
