Abstract

Product diversification through Cymbopogon citratus briquettes as an alternative fuel for the development of renewable energy. The waste from the Cymbopogon citratus production process is a potential source of renewable energy that can be used as briquettes. This is an alternative to reduce dependence on fuel oil energy which is the main need for ordinary people. The purpose of developing Cymbopogon citratus waste briquettes with various variances and the use of tapioca adhesive, in obtaining the characteristics of the calorific value of briquettes. The method of making briquettes by using a press and optimizing the composition of the appropriate mixture as an effort to get the calorific value. From this research, the calorific value of Cymbopogon citratus briquettes is 8230.65 kJ/kg at a percentage mixture of 90 : 10 and its density is 394.90 kg/m3. From the acquisition of these characteristic values, it can be recommended as an alternative fuel in an effort to develop renewable energy in the utilization of lemongrass waste.

Abstract

Study towards the recycling of PET waste has arisen in the last decades. One of the most widely used methods was the mechanical recycling process due to its simplicity and low cost of production. In this research, PET waste obtained from the disposable water gallon containers was used to produce recycled PET fibers for textile applications. The PET fibers were prepared using the extrusion technique by varying the processing temperatures, i.e., 200, 210, 220, 230, and 240°C. The diameter, FTIR analysis, XRD analysis, and mechanical properties of the PET fibers at various processing temperatures were studied. The results showed that the optimum processing temperature for preparing recycled PET fibers was 210°C with a diameter of 0.23 mm, a degree of crystallinity of 8.9%, a tensile strength of 70.4 MPa, and an elongation at break of 83.6%. In conclusion, PET waste shows a promising application to be processed as recycled PET fibers for textile applications.
