Introduction

The world is facing a significant challenge in managing organic waste, which not only pollutes the environment but also poses a threat to public health. In this context, the utilization of organic waste, such as Tempe Fermentation Liquid Waste, has emerged as an environmentally friendly and economical solution in various fields. One of the promising applications of this waste is its use as a latex clumping material to produce SIR (Synthetic Isoprene Rubber). This study aims to investigate the potential of Tempe Fermentation Liquid Waste as a latex clumping material for producing SIR and to explore its advantages and limitations.

Background

Tempeh, a fermented soybean product, is a popular food item in many parts of the world. The fermentation process produces a liquid waste that is rich in nutrients and has a high pH value. This liquid waste can be used as a clumping material for latex, which is a key component in the production of SIR. SIR is a synthetic rubber that is widely used in various industries, including automotive, aerospace, and construction. The production of SIR requires a high-quality latex clumping material, which is currently obtained from natural sources such as rubber trees.

Research Methods

In this study, we used 40 ml of formic acid as a latex clumping control and tested the quality of the resulting SIR by measuring several parameters, including early plasticity (PO), plasticity retention index (PRI), viscosity of Mooney, dirt content, ash content, and dry rubber content (DRC). We also varied the volume of liquid waste (20 ml, 40 ml, and 60 ml) and temperature (30 ° C, 35 ° C, and 40 ° C) to investigate their effects on the quality of the resulting SIR. Additionally, we added ammonia (2.5%) to some of the samples to study its effect on the quality of the SIR.

Research Results

Our results showed that the variation of volume of liquid waste with tempeh fermentation without ammonia (20 ml) at a temperature of 30 ° C produced SIR with the following values: early plasticity (PO) 43, plasticity retention index (PRI) 68.216%, viscosity of Mooney 79.714, dirt content 0.034 %, ash content 0.372%, and dry rubber content (DRC) 27.624%. Meanwhile, variations in the volume of liquid waste with tempeh fermented with ammonia (20 ml) at 30 ° C produced SIR with the following values: early plasticity (PO) 41, plasticity retention index (PRI) 63.415%, viscosity of Mooney 64.714, dirt content 0.058 %, ash content 0.134 %, and dry rubber content (DRC) 24.758%. These results indicate that the use of tempeh fermentation liquid waste as a clumping material of latex has a good potential to produce SIR with quality that is proportional to SIR-20.

Conclusion

The utilization of Tempe Fermentation Liquid Waste as a latex clumping material for producing SIR opens new opportunities in the development of a more environmentally friendly and sustainable rubber industry. The results of this study show that tempeh fermented liquid waste has good potential as a latex clumping material and needs further studies to be implemented on an industrial scale. The advantages of using tempeh fermented liquid waste as a clumping material of latex, including its environmental friendliness, economic viability, and sustainability, make it an attractive option for the rubber industry.
