Abstract

The melting process (extrusion) plays a key role in the recycling process of plastic waste into plastic pellets. This study aims to compare the recycling process of PET plastic waste between induction heating and band heater heating. The comparative analysis parameters are from the quality of the plastic pellets studied including water content, cadmium (Cd), and lead (Pb) based on SNI 8424:2017 and machine energy efficiency seen from electricity consumption and production speed. The results showed that the water content, cadmium metal content, and lead metal content of plastic pellets from the recycling process with an induction heating machine, namely 0.33%, 0.00049 ppm and 0.0633, were still far below the maximum quality standard limit even though the water content was higher than the plastic pellets produced by the band heater machine. The level of electricity consumption from the induction-heated machine was much lower with a higher production speed compared to the band heater-heated machine, namely 0.0849 kWh and 0.099 Kilogram Per Hour.

Abstract

The limited knowledge owned by KWT Sekar Arum in seedling hydroponic plant seeds and lack of manpower to maintain the seedlings caused the seeds produced to be poor (small stems and few leaf shoots) and some were eaten by pests. Poor seeds produce plants that are not optimal. Therefore, in this community service activity, a nursery chamber is designed for seedling hydroponic plant seeds that utilize solar panel energy as a source of electrical energy in indoor hydroponic plant seed cultivation. This nursery chamber is equipped with artificial light and automatic irrigation so the seedling process can save energy and time. Artificial light is made using 2 types of LED lamps with a red spectrum and a blue spectrum arranged at a certain distance so that the intensity of the light produced is 100 mol/m2/s. To be utilized optimally, all members of KWT Sekar Arum were given counseling and training related to the use of the nursery chamber. In addition, KWT Sekar Arum is also assisted in the process of transplanting and maintaining hydroponic plants so the results are maximized. Based on the results of the evaluation, it can be seen that the transfer of technology provided can be utilized properly by KWT Sekar Arum, the seeds produced from the nursery chamber already have 3-4 leaf shoots when they are 9 days old and ready to transplant, and the results of hydroponic plants produced has been maximized with wide and many leaves.
