Plastic waste is one of the triggers of environmental pollution. Most plastics used are not biodegradable. So it is important to look for alternative plastic materials that are environmentally friendly and biodegradable. Raw materials that can be used as alternatives for making biodegradable plastics include gelatin and seaweed. Gelatin raw material used is the skin of catfish and seaweed Euchema cottonii.
The use of these two raw materials is due to the ease of obtaining them in the Indonesian region. Gelatin is made by soaking the skin of catfish that has been cut into pieces with an acid solution, then rinsed and extracted with water at a temperature of 65 degrees Celsius. Seaweed porridge is made by blanching seaweed and then soaked with water and blended. Then all that is left is to mix all the ingredients together then print using a mold and dried in the oven.
Bioplastics that can be decomposed by microbes in the soil so that it does not pollute the environment
- Raw materials are easy to get
- Safe for the environment
- Affordable prices

According to the study’s results, it is proven that Pseudomonas aeruginosa’s growth with the addition of crookneck pumpkin (Curcubita moschata) seed extract is faster than the culture with no treatment. Amino acids have a vital role in growth and lipolytic enzyme production. This shows that crookneck pumpkin seed extract can be a supplement to increase growth rate and lipolytic enzyme activity of Pseudomonas aeruginosa. The lipolytic enzyme produced is suggested to degrade plastic.
The protein extract from crookneck pumpkin seed can be used as a supplement to increase growth rate and lipolytic enzyme activity. Besides that, this finding can increase the utilization of crookneck pumpkin seed.
Amino acids, arginin, alanin, and isoleusin in pumpkin seeds can increase growth rate of Pseudomonas aeruginosa. P. aeruginosa can degrade microplastic.

Supervisor: Ir. Wahyu Purwakusuma, MSc
This research is motivated by the issue of environmental pollution and social problems that arise around the Galuga sub-district, Bogor regency. This study aims to treat leachate water in the Final Disposal Site (TPA) galuga into liquid fertilizer, by utilizing phytoremediation by hyperaccumulator plants such as Kiambang.
Research can be used as an alternative to reducing waste, as well as environmentally friendly waste management.
Liquid fertilizer-based products that are easily applied.
