Abstract

This study applies the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method to evaluate occupational health and safety (OHS) risks in the steel pipe manufacturing industry, specifically in machine installation and construction works performed by third-party contractors at PT. XYZ in East Java. These tasks are known for their elevated risk profiles due to limited supervision and differing OHS standards among contractors. The research adopts a qualitative approach through direct observation and interviews, analyzing risks using the ISO 45001:2018-aligned HIRADC framework. A total of 43 hazards were identified and initially categorized into 16 low, 20 medium, and 7 high-risk hazards. Following the implementation of control measures based on the hierarchy of controls (elimination, substitution, engineering, administrative controls, and PPE), risks were significantly reduced to 35 low and 8 medium-risk hazards. The findings highlight the effectiveness of systematic risk management and reinforce the need for continuous improvement in administrative and engineering controls. Regular evaluations are recommended to ensure the sustainability and responsiveness of the OHS system to evolving workplace conditions.

Abstract

Penelitian ini bertujuan untuk mengevaluasi kelayakan penerapan konsep ekonomi sirkular dalam pengolahan limbah cair industri Monosodium Glutamate (MSG) menjadi produk pupuk daun dan pupuk buah sebagai upaya mendukung industri pupuk yang berkelanjutan. Limbah cair yang mengandung unsur hara seperti nitrogen, fosfor, dan kalium dimanfaatkan kembali sebagai bahan baku pupuk cair berbasis organik. Analisis dilakukan terhadap nilai Benefit-Cost Ratio (B/C Ratio), Payback Period (PP), dan Break-Even Point (BEP) dengan pendekatan data keuangan dari produksi PT. ABC pada tahun 2025. Hasil menunjukkan bahwa B/C Ratio untuk pupuk daun mencapai 425% dan pupuk buah 234%, keduanya jauh di atas ambang kelayakan minimum sebesar 100%. Waktu pengembalian modal hanya 0,96 tahun (11,5 bulan), serta nilai BEP tercapai pada 3 liter pupuk daun (Rp 116.000) dan 2 liter pupuk buah (Rp 60.000). Temuan ini membuktikan bahwa pengolahan limbah cair industri menjadi pupuk cair tidak hanya layak secara finansial, tetapi juga mendukung prinsip keberlanjutan dan efisiensi sumber daya dalam kerangka ekonomi sirkular. Oleh karena itu, kegiatan ini direkomendasikan untuk terus dilanjutkan dan dikembangkan

Abstract

This study aims to determine the technical specifications of a digital QR Code system for the weighing process of practical spice powder recipes using Axiomatic House of Quality to prevent human error. User requirements data were collected from 25 respondents and validated through a Focus Group Discussion (FGD) involving 9 technical experts. The results identified 14 Customer Attributes (CA), which were subsequently translated into 14 Design Parameters (DP). Design matrix analysis indicated that the system is categorized as an uncoupled design, where each Functional Requirement corresponds to a specific DP, thus maintaining the independence of functions and design parameters. The resulting technical specifications are practical and applicable, covering hardware components, user interface, alarms, data storage systems, and material detection mechanisms. Therefore, the designed digital QR Code system can prevent weighing errors caused by human error and enhance product quality from the consumer’s perspective
