As we know, coffee is a refreshing drink that is very popular in the world and is consumed related to aspects of consumer: refreshment and satisfaction. Coffee is the second traded commodity in the world, with global revenue reaching $68.5 billion, and 15% of which is instant coffee. However, currently the main problem experienced by the instant coffee industry is production costs which tend to continue to increase due to the use of excess energy in thermal evaporation and drying reaching 40.8 MJ/kg of instant coffee. Therefore, the efforts made by the UNDIP Vocational School Research Team in making contributions and contributions through applied research in order to reduce production costs and improve the quality of instant coffee to become a competitive premium. For this reason, SV UNDIP formed a research consortium with collaborations including: RPM Study Program, TRKI SV UNDIP, Sirap Coffee Industry Partners, Mas To New Star Workshop, CV. Teguh Jaya Ungaran and BILK, Semarang Metal and Wood Industry Center. This effort turned out to be fruitful, so that this applied research was funded by the Ministry of Education and Culture through the PTUPT scheme, Higher Education Excellence Applied Research for a period of 3 years with the title “DEVELOPMENT OF STEAM NANO DISPERSION PROCESS -VIBRO NANO FILTRATION FOR PREMIUM INSTANT COFFEE PRODUCTION”. The development of process integration through a subcritical extractor machine based on nano dispersed steam and vibro nano filtration has been able to reduce energy costs for thermal evaporation and drying by up to 30%.
The research team with coordinator Drs. Sutrisno, M.T, whose members are Mohamad Endy Yulianto, S.T, M.T., Didik Ariwibowo, S.T., M.T, Dr. Eng. Vita Paramita, S.T., M.M., M.Eng, Ria Desiriani, S.T., M.T. assisted by students Rega Ardiansyah, Anita Carolina, Abitha Monawisya, Belinda Azhara. The production of premium instant coffee by developing a high efficient subcritical extraction system based on nano disperse steaming and vibro nano filtration is currently in the process of registering a patent, according to Tris, his nickname. So that after the patent has been granted and certified, it is hoped that instant coffee industry players can immediately develop it. This will greatly assist in solving the problems experienced by the instant coffee industry throughout Indonesia. Drs. Sutrisno, M.T. as the person in charge of this activity, his work is no longer in doubt. The owner of 16 patents & intellectual property rights always gets research grants competitively every year. In fact, the LPPM UNDIP has been entrusted in the last few years to carry out community service activities, this is inseparable from the competence he has. Together with the team, various technological results have been disseminated to industry players including: zeolite-based adsorption dryers for the candied pineapple industry, mixed flow dryers for the coffee industry, cashew industry and others. This research consortium is very solid because it is supported by competent MBKM students with coordinator Rega Ardiansyah, a TRKI student class of 2019, even though they have not graduated yet, they have been proposed to by the largest petrochemical company in Asia, namely PT. Lotte Chemical Indonesia. “This is inseparable from the research that has been carried out with lecturers since the beginning of 2020 until now which has made them skilled, innovative and competent, in addition to the myriad of competency certificates they have,” said Endy, as a member of the Team as well as the Head of TRKI Study Program. Thus, this activity is expected to be able to pioneer the production of competitive premium instant coffee through well-proven technology with royalty sharing in the technology sector.
Impact of research results/activities for Indonesian agriculture:
The impact of the research results are: (i) will encourage the creation of national independence in the production of premium instant coffee, (ii) high market potential and mastery of steaming-based hydrothermal extraction technology is a promising investment attraction for the coffee industry to carry out the commercialization of premium instant coffee as a result of this research, (iii) the commercialization of agriculture-based technology resulting from this research has high prospects and will encourage economic growth, (iv) for the community, the nation’s independence in producing premium instant coffee will open up new jobs, (v) the availability of reliable and inexpensive technology for super coffee production so that the empowerment of farmers will develop in the field of cultivation coffee plants, (vi) a positive impact on the cultural behavior of the community to optimally empower all local agricultural-based potentials, and (vii) the formation of an integrated network of collaboration between researchers from various different institutions with the support of the resources they have.
