Abstract

One source of natural fiber whose utilization still needs to be developed is fiber from corn husk which is cheap, abundant and environmentally friendly. The increasing production of corn plants causes an increase in corn husk waste which is also higher. Even though this corn husk has very strong fiber and can be used as a composite of natural fibers. Composites reinforced with natural fibers have excellent corrosion resistance properties, as well as lower production costs, are more abundant and are considered to be more environmentally friendly. The aim of the study was to determine the effect of soaking 7% NaOH for 1 hour, 2 hours and 3 hours and the effect of curing time at temperatures of 95°, 105° and 115° for 4 hours on the tensile strength of the corn husk fiber woven composite and to determine whether corn husk woven fiber composite can be applied as a car bumper manufacture. Making samples using the hand lay-up method. The analysis was performed using the factorial method. The highest results were found in the tensile test specimens using a variation of NaOH immersion time for 2 hours at a temperature of 95°C having a tensile test strength of 19.93 MPa. Meanwhile, the lowest tensile test strength value was 12.13 MPa using a variation of NaOH immersion time for 3 hours with a temperature of 115°C. Based on the standard for making car bumpers, the corn husk woven fiber composite can be applied as an alternative material for making car bumpers.

Abstract

Occupational Safety and Health (OSH) is a vital component in creating a safe, healthy, and productive work environment while protecting workers from the risks of accidents and work- related illnesses. This article provides an in-depth review of the basic concepts of OSH, the underlying regulations, workplace risk factors, and effective implementation strategies. In Indonesia, OSH implementation is governed by Law No. 13 of 2003 on Manpower and Law No. 1 of 1970 on Occupational Safety. Despite the availability of regulations, OSH implementation still faces various challenges, particularly in the informal sector and small and medium enterprises. This article identifies various risk factors that can affect the safety and health of workers, including physical, chemical, biological, ergonomic, and psychosocial risks. Strategies such as strong policy formulation, continuous training, routine audits, and active worker participation can help minimize these risks. The use of modern technology, such as automated detection devices and safety sensors, also supports more effective risk management. The findings of this study reveal that optimal OSH implementation not only reduces workplace accidents and work-related illnesses but also provides significant benefits for companies. These benefits include increased productivity, operational efficiency, worker motivation, and the organization's reputation as an entity that cares about employee welfare. Therefore, OSH is not merely a legal obligation but also a strategic investment that supports business sustainability and long-term worker welfare
