Students of the Industrial Chemical Engineering Technology (TRKI) Study Program, Vocational School, Diponegoro University (UNDIP) have once again achieved impressive national-level recognition. Three student teams successfully secured funding in various prestigious research competitions in 2025, demonstrating the research and innovation capabilities of TRKI students in addressing industrial and environmental issues.
1. Palm Oil Research: Bio-Filter Innovation from TKKS Waste and Magnetic Biochar
In the 2025 Palm Oil Research Competition for Students organized by the Palm Oil Plantation Fund Management Agency (BPDPKS), the team led by Irgy Khairoel Al Fahrezi and mentored by Abdullah Malik Islam Filardli, S.T., M.T., secured funding with their research titled: “Development of a Bio-Filter Based on TKKS and Magnetic Biochar Modified with FeCl to Improve the Efficiency of BOD, COD, and Heavy Metal Absorption in Palm Oil Mill Effluent (POME)”.
This research aims to develop biofiltration technology using empty fruit bunch (TKKS) waste and magnetic biochar as a more efficient and environmentally friendly solution for processing palm oil mill wastewater. The team also includes Farid Alpharaby, Marsya Rizkya Ramadhani, Fadlie Fadila, and Stefany Sebayang.
2. PKM: ClearaSpray — Anti-Scale Spray from Siwalan Sap
The second team secured funding in the Student Creativity Program (PKM) 2025 organized by the Directorate General of Higher Education, Research, and Technology (Ditjen Diktiristek) with an innovation titled: “ClearaSpray: An Innovative Product Based on Siwalan Sap as a Natural and Eco-Friendly Anti-Scale Spray for Glass Laboratory Equipment”.
ClearaSpray is a natural solution for removing scale on laboratory equipment without the use of aggressive chemicals, utilizing the potential of siwalan sap as an organic cleaning agent. The team is led by Alam Surya Negara and mentored by Dr. Ir. Fami Arifan, S.T., M.Eng., M.M., IPM., ASEAN Eng. The team members come from various departments: Senifa Azzahra (FEB), Salsa Kamilia, Amsal Jobit Mangaraja Sinaga, and Mohamad Rasyid Bahaudin (TRKI).
3. PKM-RE: Antibacterial Gel from Palm Shell Charcoal and Tea Tree Oil
The third achievement comes from the Exact Science Research Student Creativity Program (PKM-RE) with the research titled: “Formulation of Gel Preparation Based on a Combination of Palm Shell Activated Charcoal and Tea Tree Oil as an Antibacterial”.
This research utilizes palm shell waste that is processed into activated charcoal, combined with tea tree oil to create a gel formulation that acts as a natural antibacterial, with potential applications in pharmaceuticals and personal care. The team is led by Muhammad Amyra Faiz with the guidance of lecturer Sri Risdhiyanti Nuswantari, S.T., M.T., and consists of Aini Silvia Astha, Lailatul Safitri, Al Fariza, and Abellia Puteri Hapsari.
