Abstract

Persaingan bisnis semakin ketat seiring dengan perkembangan dan perubahan zaman, yang mana perubahan tersebut menuntut perusahaan agar senantiasa menghasilkan produk berkualitas dan kompetitif guna memenuhi harapan dan persyaratan /spesifikasi pelanggan. Perusahaan PT. X Surabaya merupakan salah satu industri yang bergerak pada sektor industri manufaktur (perakitan) peralatan medis, antara lain produk timbangan digital, tensi meter, pulse oximeter dan sebagainya. Dalam visinya perusahaan berkomitmen tinggi menghasilkan produk bermutu, ramah lingkungan dan berdaya saing tinggi. Dalam rangka upaya peningkatan kualitas (quality improvement), perusahaan perlu menerima masukan yang berkaitan dengan isu-isu kualitas baik dari internal maupun eksternal perusahaan (keluhan pelanggan). Pada tahun 2021 terdapat 32 keluhan pelanggan terkait kualitas produk timbangan digital kesehatan. Dari data rejection rate yang terdokumentasi pada tahun 2020 – 2021, untuk produk timbangan mencapai 0,80% hingga 2,53% dengan jumlah produk cacat terbanyak 127 unit dari total produksi 5010 unit. Nilai tersebut masih di luar batas sasaran mutu perusahaan yaitu maksimal 2% dari total produksi. Permasalahan-permasahan di atas disebabkan karena proses pengendalian kualitas yang dilakukan oleh internal perusahaan masih belum optimal dan kesadaran sumber daya manusia terhadap mutu produk masih rendah. Untuk menurunkan terjadinya produk cacat di masa mendatang, konsep zero defect digunakan sebagai alat manajemen yang ditujukan untuk mengurangi cacat produk melalui pencegahan. Tindakan pencegahan tersebut dapat dianalisis menggunakan pendekatan root cause analysis dan model House of Risk (HOR), dimana keduanya berperan untuk mengidentifikasi dan mengetahui hubungan antara peristiwa resiko dan penyebabnya hingga menentukan prioritas rekomendasi dari penyebab kritis. Dari penelitian yang telah dilakukan, diperoleh 42 risk event yang berdampak pada kerusakan produk dengan kategori critical, major, minor berurutan sebanyak 21, 11, dan 8 jenis serta mendapatkan 49 risk agent berdasarkan root cause analysis. Hasil analisa HOR mendapatkan 3 nilai ARP tertinggi sebesar 155673, 80496, dan 78138 dengan penyebab masalah secara berurutan yaitu belum diberlakukan pelatihan dan sosialisai karyawan secara rutin sesuai dengan kebutuhan pekerjaan, SOP dan IK untuk update database belum ada, dan monitoring hasil kualitas secara manual masih sulit dilakukan. Sehingga didapatkan 9 poin rekomendasi (preventive action) yang berdampak dalam mereduksi potensi adanya cacat produk antara lain perencanaan pelatihan dan sosialisasi kepada karyawan, penyempurnaan SOP dan IK, merancang dashboard untuk quality control, merancang peta kerja tangan kanan dan kiri proses perakitan, merencanakan sampling plan yang tepat guna, merancang desain jig/fixture untuk proses perakitan, merancang desain holder/casing untuk mainboard assembly, meningkatkan standar pengujian, serta merencanakan untuk pengelolaan supplier bahan baku.
===============================================================================================================================
Business competition is becoming increasingly tight with the development and changes of the times, which demands companies to always produce high-quality and competitive products to meet customer expectations and specifications. PT. X Surabaya is one of the industries that operates in the medical equipment manufacturing sector, including digital health scales, blood pressure meters, pulse oximeters, and so on. In its vision, the company has a high commitment to producing high-quality, environmentally friendly, and highly competitive products. In order to improve quality (quality improvement), the company needs to accept input related to quality issues both from within and outside the company (customer complaints). In 2021, there were 32 customer complaints related to the quality of digital health scales. From the documented rejection rate in 2020-2021, the rejection rate for digital health scales reached 0.80% to 2.53% with the highest number of defective products at 127 units out of a total of 5,010 units. This value is still outside the company's quality target of a maximum of 2% of total production. The problems above are due to the insufficient quality control process carried out by the company and the low awareness of human resources regarding product quality. To reduce the occurrence of defects in the future, the zero defect concept is used as a management tool aimed at reducing product defects through prevention. The preventive actions can be analyzed using root cause analysis and the House of Risk (HOR) model, both of which play a role in identifying and understanding the relationship between risk events and their causes, and determining the priority recommendations from the critical cause. From the research that has been carried out, 42 risk events that have an impact on product damage have been obtained, with critical, major, and minor categories in order of 21, 11, and 8, also 49 risk agents have been obtained based on root cause analysis. The results of the HOR analysis found the 3 highest ARP values to be 155673, 80496, and 78138 with the problem causes in order of not having regular employee training and socialization according to job requirements, no update of the SOP and IK database, and manual quality control results monitoring being difficult. Thus, 9 preventive action recommendations were obtained that have an impact in reducing the potential for product defects, such as employee training and socialization planning, refining SOP and IK, designing a dashboard for quality control, designing a work map for the right and left assembly process, planning the right sampling plan, designing jigs/fixtures for the assembly process, designing holders/casings for mainboard assembly, increasing testing standards, and planning supplier material management.
