Abstract

This study analyzes quality control for tofu products at SM Sari Murni Tofu Factory using Statistical Quality Control (SQC) and Failure Mode and Effect Analysis (FMEA) methods. The study aims to evaluate the defect level, identify key causes of defects, and propose improvement measures. The results from SQC indicate that tofu product defects are within not acceptable tolerance limits. This method utilizes statistical tools such as control charts to monitor production process variability, improve efficiency, and reduce costs. Meanwhile, FMEA successfully identified two critical processes, namely cutting and pressing, with the highest Risk Priority Numbers (RPN) of 648 and 504, respectively. These findings highlight the need for improvements, including enhanced machine reliability, operator training, and stricter production process monitoring. The combination of SQC and FMEA proved effective in reducing defect rates, improving product quality, and maintaining market competitiveness. This study provides strategic recommendations for SM Sari Murni Tofu Factory to achieve continuous quality improvement.  Keywords: Quality Control, Statistical Quality Control, Failure Mode and Effect Analysis, Product Defects, Tofu Factory   Abstrak Penelitian ini menganalisis pengendalian kualitas produk tahu di Pabrik Tahu SM Sari Murni dengan menggunakan metode Statistical Quality Control (SQC) dan Failure Mode and Effect Analysis (FMEA). Penelitian ini bertujuan untuk mengevaluasi tingkat kewajaran cacat produk, mengidentifikasi penyebab utama kecacatan, serta memberikan usulan perbaikan. Hasil analisis menggunakan SQC menunjukkan bahwa tingkat kecacatan produk tahu berada dalam batas toleransi yang tidak dapat diterima. Metode ini memanfaatkan alat statistik seperti peta kendali untuk memantau variabilitas proses produksi, meningkatkan efisiensi, dan mengurangi biaya. Sementara itu, FMEA berhasil mengidentifikasi dua proses kritis, yaitu pemotongan dan pengepresan, dengan nilai Risk Priority Number (RPN) tertinggi masing-masing sebesar 648 dan 504. Temuan ini menunjukkan perlunya langkah perbaikan, seperti peningkatan keandalan mesin, pelatihan operator, dan pengawasan yang lebih ketat terhadap proses produksi. Kombinasi penerapan SQC dan FMEA terbukti efektif dalam mengurangi tingkat kecacatan, meningkatkan kualitas produk, serta menjaga daya saing produk tahu di pasar. Penelitian ini memberikan rekomendasi strategis bagi Pabrik Tahu SM Sari Murni dalam meningkatkan kualitas produk secara berkelanjutan.   Kata Kunci: Pengendalian Kualitas, Statistical Quality Control, Failure Mode and Effect Analysis, Kecacatan Produk, Pabrik Tahu

Abstract

This study aims to test the quality of logistics Anteraja, using SERVQUAL method and Important Performance Analysis using five dimensions of SERVQUAL, namely Tangible, Assurance, Responsiveness, Reliability, and Empathy. This study uses a quantitative approach through a survey of 100 respondents. The results will be collected using a Google form and then will be processed through reliability and validity tests using SPSS and analyzed using SERVQUAL, which is subtracting perception and expectation score and then will be mapped through the Important Performance Analysis quadrant. Based on important performance analysis quadrant, six service atribut were found that need an immediate improvement such as the readiness of courier in delivering packages, the speed of customer service in responding to complaint or problem, the politeness of courier in their interaction with customer, the ability of employee toexplain the service offered, the timeliness of delivery by couriers in accourdance to their service, and the timeliness of pick up in accordance within the time range Keywords: IPA, SERVQUAL, Quality Service, Anteraja   Abstrak Penelitian ini bertujuan untuk menguji kualitas jasa logistik Anteraja menggunakan metode SERVQUAL dan Important Performance Analysis menggunakan lima dimensi SERVQUAL yaitu Tangible, Assurance, Responsiveness, Reliability, dan Empathy.

Abstract

The community-based empowerment carried out at home industries in Ciantra Village is a form of dedication by the Higher Education staff to community groups in producing butterfly pea-based processed products. The problems faced by partners, namely the drying process of butterfly pea flowers is still done conventionally by drying in the sun, and the drying process takes quite a long time, especially during the rainy season. Solutions that can be offered to overcome these problems with the application and assistance of infrared burner technology-based dryers. The aim of the community partnership empowerment program activities is to carry out technology transfer to home industries and to improve the quality of butterfly pea products. The stages of the activities used in the implementation of the community partnership empowerment program are socialization, application of the dryer, how to use the dryer, assistance, and evaluation. The results achieved through this program are that partners are able to understand the process of drying butterfly pea flowers, are skilled in the drying process of butterfly pea using the technological innovations that have been provided, and the availability of dryers based on infrared technology that partners can use to improve the drying results of butterfly pea flowers.
