Abstract

The Indonesian tofu industry faces challenges in the soybean grinding stage, which is still dominated by small-scale machines with limited capacity, poor grinding quality, and low energy efficiency. These constraints reduce the productivity and competitiveness of micro, small, and medium enterprises (MSMEs). This study aims to design a more efficient tofu grinding machine that meets user needs by applying the Quality Function Deployment (QFD) method. Using a descriptive approach with quantitative support, consumer needs (Voice of Customer) were identified, translated into technical responses, and analyzed through the House of Quality (HoQ) to determine technical priorities. Results show that consumers demand large production capacity, smooth grinding results, energy efficiency, durability, and easy maintenance. The highest-priority technical responses include high-power motors, stainless steel piping, and large-capacity grinding tubes.

Abstract

Jet dyeing machines, essential for producing high-quality and environmentally friendly textiles, face persistent issues with defects that lead to production stoppages, compromised cloth quality, and significant financial losses for companies. These challenges hinder operational efficiency and undermine the competitive edge of textile manufacturers in a rapidly evolving market. Jet Dyeing machines continue to innovate to produce high quality and environmentally friendly textiles, with the discovery of defects causing cloth production to stop, cloth quality to decline, and company losses. The Fuzzy-FMECA approach enhances accuracy and adaptability in identifying failure risks, improving maintenance for complex jet dyeing systems. This study aims to identify the root causes of jet dyeing machine damage for preventive maintenance design. Studies using robust fuzzy-FMECA can identify critical components of jet dyeing machines with a high degree of accuracy. This can improve machine reliability and reduce fabric quality failures. The dominant machine failures identified in jet dyeing components are leakage, short circuits, and installation errors. The Pareto analysis shows that leaks, tears, and short circuits are responsible for over 70% of total failures. The most critical components include the main pump and electric socket, both with an RPN score of 7.42, representing a significant 30% of overall risk. Other high-risk components such as the steam pipe packing and heat exchanger steam pipe also have an RPN of 7.25. These findings indicate that over 60% of the failures arise from just a few key components. These findings have succeeded in identifying the critical components of the jet dyeing machine (main pump and socket) which have the highest potential risk of failure. The proposed preventive maintenance design can reduce these risks, but needs to be refined with consistent, competent and monitored inspections. The preventive maintenance design significantly mitigates risks, requiring ongoing refinement through regular, skilled, and supervised inspections to ensure optimal effectiveness.

Abstract

IKM Tempe XYZ menghadapi kesulitan dalam menjaga efisiensi proses produksi. Penelitian ini bertujuan untuk mengidentifikasi pemborosan utama pada proses produksi tempe di IKM Tempe XYZ guna meningkatkan efisiensi operasional. Pendekatan dalam penelitian ini menggunakan metode deskriptif kuantitatif dengan pengumpulan data melalui kuesioner terkait adanya tujuh jenis waste. Data tersebut kemudian dianalisis menggunakan metode keputusan Borda untuk menentukan prioritas waste utama, dilanjutkan dengan analisis akar penyebab berbasis fishbonediagram untuk mengidentifikasi faktor-faktor penyebab utama dari masalah tersebut. Hasil analisis menunjukkan bahwa pemborosan transportasi akibat pemindahan bahan secara manual menjadi prioritas utama dengan skor tertinggi, yaitu 32. Pemborosan ini terjadi karena aktivitas pemindahan kedelai secara berulang akibat tata letak lokasi yang tidak efisien dan minimnya alat bantu seperti troli. Untuk mengatasi permasalahan tersebut, disarankan untuk melakukan perancangan ulang tata letak proses produksi berdasarkan alur linier yang efisien serta menyediakan troli stainless untuk mempercepat pemindahan bahan. Usulan perbaikan ini diharapkan dapat mengurangi meningkatkan produktivitas secara keseluruhan.Kata Kunci:  Metode Borda, Produksi Tempe, Pemborosan Transportasi.

Abstract

The effectiveness of production machines is a key factor in increasing the productivity and competitiveness of the manufacturing industry. CNC Lathe machines as one of the main machines in the machining process are required to operate optimally with a high level of reliability and quality. This study aims to analyze the level of effectiveness of CNC Lathe machines using the Overall Equipment Effectiveness (OEE) method and identify the sources of production losses based on the Five Big Losses concept. The research method used is a quantitative approach with a case study on one CNC Lathe machine unit in a manufacturing company with a make-to-order production system. Research data were obtained through direct observation of machine working time, downtime, number of outputs, and the number of defective products during one production shift. The results showed that the availability value was 94.10%, performance was 98.28%, and quality was 99.50%, resulting in an OEE value of 92.01%. This value has exceeded the world-class standard of 85%, which indicates that the performance of the CNC Lathe machine is in the very good category. The Five Big Losses analysis shows that the dominant losses come from breakdown losses and idling and minor stoppages. This research contributes by evaluating the performance of a CNC lathe machine in a contextualized make-to-order production system and recommending improvements to maintain and enhance machine effectiveness.

Abstract

The effectiveness of production machinery is one of the key factors determining the success of manufacturing processes, particularly in the pharmaceutical industry, which demands high accuracy and consistent product quality. PT XYZ utilizes the Romaco Killian KTP 720X as one of its main machines in the tablet compression process. However, during the period from January to September, the machine's production output did not meet the company’s target. This condition highlights the need for a systematic evaluation of the machine’s performance. This study was conducted using the Overall Equipment Effectiveness (OEE) method, a comprehensive indicator used to assess machine effectiveness based on three main components: availability, performance, and quality. Production data were collected through direct observation, company documentation, and interviews, covering loading time, downtime, operation time, actual output, number of defective products, and the machine’s ideal cycle time. The results show that the machine’s average availability was 68.00%, performance was 29.14%, and the quality rate reached 99.11%. These components generated an OEE value of 19.52%, which is significantly below the international standard of 85% established by the Japanese Institute of Plant Maintenance (JIPM). The low OEE value is primarily attributed to the performance component, which falls far below the required standard, indicating that the machine does not operate at its ideal speed. These findings underscore the need to improve process efficiency, optimize machine speed settings, and evaluate operational procedures to enhance machine performance and ensure the achievement of the company's production targets.
