Abstract

Proses pemilahan biji kopi secara manual merupakan tahapan krusial dalam industri pengolahan kopi, terutama pada segmen specialty coffee, namun seringkali belum memenuhi prinsip ergonomi yang baik. Aktivitas ini dilakukan dalam posisi duduk statis dengan durasi yang lama dan gerakan repetitif, sehingga berpotensi menimbulkan gangguan otot dan rangka. Penelitian ini bertujuan untuk mengidentifikasi dan mengevaluasi risiko ergonomi yang dihadapi oleh pekerja pemilah biji kopi menggunakan pendekatan Standar Nasional Indonesia 9011:2021 tentang penilaian risiko ergonomi. Penilaian dilakukan melalui kuesioner keluhan GOTRAK, daftar periksa potensi bahaya ergonomi, serta observasi langsung terhadap postur kerja, durasi paparan, dan aktivitas pengangkatan beban. Selain itu, pendekatan 5S diterapkan sebagai strategi identifikasi potensi bahaya ergonomi dari aspek lingkungan kerja, guna mendukung pengendalian risiko secara sistematis. Hasil penelitian menunjukkan bahwa penerapan prinsip 5S menunjukkan masih rendahnya keteraturan, kebersihan, dan disiplin kerja di area sortir manual. Lingkungan kerja masih belum optimal dalam mendukung postur kerja ergonomis. Elemen Seiri (pemilahan barang) dan Seiton (penataan barang) masih belum diterapkan secara maksimal, terbukti dari tata letak alat kerja yang tidak efisien dan keterbatasan ruang gerak pekerja. Penilaian risiko ergonomi berdasarkan SNI 9011:2021 menunjukkan bahwa pekerja pemilah biji kopi mengalami tingkat paparan risiko yang berada pada tingkat tinggi dengan skor total antara 9 hingga 13. Berdasarkan hasil kuesioner GOTRAK yang disebarkan pada empat pekerja, ditemukan keluhan paling dominan terjadi pada punggung bawah, leher, dan bahu. Berdasarkan temuan tersebut, penelitian ini memberikan rekomendasi perbaikan berupa desain stasiun kerja ergonomis, mencakup rancangan meja sortir dengan kemiringan tertentu, sekat pelindung sisi meja, serta kursi kerja berbantalan untuk mengurangi tekanan tubuh bagian bawah. Rekomendasi ini diharapkan mampu meningkatkan kenyamanan, mengurangi risiko cedera kerja, serta mendukung produktivitas tenaga kerja secara berkelanjutan di sektor UMKM kopi.

The manual coffee bean sorting process is a crucial stage in the coffee processing industry, especially in the specialty coffee segment, but often does not meet good ergonomi principles. This activity is carried out in a static sitting position with a long duration and repetitive movements, so it has the potential to cause muscle and skeletal disorders. This study aims to identify and evaluate the ergonomi risks faced by coffee bean sorting workers using the Indonesian National Standard 9011:2021 approach on ergonomi risk assessment. The assessment was carried out through the GOTRAK complaint questionnaire, a checklist of potential ergonomi hazards, and direct observation of work posture, exposure duration, and lifting activities. In addition, the 5S approach was applied as a strategy for identifying potential ergonomi hazards from the work environment aspect, in order to support systematic risk control. The results of the study showed that the application of the 5S principle showed that the orderliness, cleanliness, and work discipline in the manual sorting area were still low. The work environment is still not optimal in supporting ergonomi work postures. The elements of Seiri (sorting goods) and Seiton (arranging goods) have not been implemented optimally, as evidenced by the inefficient layout of work tools and limited space for workers to move. Ergonomi risk assessment based on SNI 9011:2021 shows that coffee bean sorting workers experience a high level of risk exposure with a total score of 9 to 13. Based on the results of the GOTRAK questionnaire distributed to four workers, it was found that the most dominant complaints occurred in the lower back, neck, and shoulders. Based on these findings, this study provides recommendations for improvements in the form of ergonomi workstation design, including the design of a sorting table with a certain slope, protective partitions on the side of the table, and cushioned work chairs to reduce lower body pressure. These recommendations are expected to increase comfort, reduce the risk of work injuries, and support sustainable workforce productivity in the coffee MSME sector.
