K3 merupakan suatu permasalahan yang banyak menyita perhatian berbagai organisasi saat ini karena mencakup permasalahan segi perikemanusiaan, biaya, pertanggung jawaban serta citra organisasi itu sendiri. Saat ini perusahaan dapat dikatakan belum menerapkan K3 dengan baik. Hal-hal tersebut dapat menyebabkan kecelakaan kerja dan penyakit akibat kerja. Oleh karena itu, diperlukan dilakukan upaya pencegahan kecelakaan kerja dan penyakit akibat kerja, salah satunya dapat dilakukan dengan cara analisis risiko. Salah satu metode HIRARC (Hazard Identification, Risk Assesment, and Risk Control). Metode ini terdiri dari 3 tahapan yaitu identifikasi bahaya, penilaian risiko, dan penentuan pengendalian berdasarkan data. Identifikasi bahaya dilakukan dengan cara melakukan wawancara dan observasi karyawan dan pemilik industri, sedangkan penilaian risiko dilakukan dengan cara menyebarkan kuesioner penilaian tingkat kemungkinan dan keparahan terjadinya risiko setiap potensi bahaya. Kuesioner ini disebarkan kepada karyawan dan pemilik salah satu rumahan industri tahu. Setelah didapatkan indeks risiko dari setiap potensi bahaya, langkah selanjutnya adalah menetapkan langkah-langkah pengendalian risiko. Berdasarkan hasil penelitian, didapatkan 19 potensi bahaya pada proses pembuatan tahu, dimana 15,9% merupakan bahaya dengan kategori risiko rendah, 36,9% merupakan bahaya kategori risiko sedang, dan 47,2% merupakan bahaya kategori risiko tinggi. Pekerjaan dengan risiko tingkat tinggi berada pada kegiatan perebusan tahu, menggoreng tahu dan pemberian larutan pengendap tahu. Pengendalian yang dapat dilakukan untuk mengurangi risiko antara lain adalah penggunaan Alat Pelingdung Diri (APD) bagi pekerja, sehingga pekerja dapat dengan aman dan nyaman dalam bekerja, dan dipasangkan rambu-rambu peringatan pada setiap sudut ruang produksi untuk mencegah terjadinya hal-hal yang tidak diinginkan.

Efficiency and quality are two crucial factors in the manufacturing industry in Indonesia. PT. SASL and Sons Indonesia is a manufacturing company in the coconut processing industry, with various stages of production separated into different rooms. However, the production room layout was found to be inefficient due to the distance and size between the rooms, which affected the flow of material movement. To address this issue, the Computerized Relationship Layout Method (CORELAP) was used to redesign the layout of each production room and improve the flow of material movement. Factors considered in the redesign included the sequence of production processes, the distance of material movement, and the dimensions of the machine and material handling equipment. The new layout resulted in a material movement distance of 53.963 meters, a reduction of 86.7% from the initial layout's distance of 406.75 meters. This study demonstrates the importance of optimizing production room layout for improved efficiency and material movement, which can ultimately lead to better quality products and customer satisfaction.
