Waste Is Not the End, Polibatam Proves TPST Compost Can Become a Sustainable Solution

BATAM – Politeknik Negeri Batam (Polibatam) continues to strengthen its commitment as a green and sustainable campus through the Demonstration Plot for Quality Testing of TPST Polibatam Compost Products. The activity is carried out at a trial garden located behind the futsal/tennis field area of Polibatam.

The demonstration plot was developed using five raised beds and hundreds of polybags as planting media to test the quality of compost produced from the processing of organic waste, particularly leaves and grass collected from the campus environment. The compost is a product of Polibatam’s Integrated Waste Processing Facility (TPST), which was developed as part of efforts to manage organic waste in a more productive and sustainable way.

In this trial, TPST Polibatam compost was used as a supporting medium for the growth of water spinach. The harvesting process was carried out on Friday afternoon, 26 June 2026, as part of the initial evaluation stage to observe the results of using the compost in the trial garden.

Through this activity, Polibatam aims to assess how far compost produced from campus organic waste can support plant growth. Moving forward, the compost will also undergo laboratory testing to determine its nutrient content and quality in a more measurable manner.

This activity does not only focus on compost quality testing, but also represents a concrete step toward creating a circular economy within the campus environment. Leaves and grass that previously had the potential to become waste are now processed into useful products that can support urban farming activities and open opportunities for broader community economic development.

In addition to supporting better environmental management, this initiative is also part of Polibatam’s efforts to strengthen the implementation of green campus practices and improve its UI GreenMetric (UIGM) rating achievements. Through simple yet impactful innovation, Polibatam continues to encourage environmental awareness, sustainable resource utilization, and practical learning within the campus environment.

Polibatam hopes that this demonstration plot can become an example of productive, educational, and sustainable organic waste management. This step also reinforces the role of the campus in promoting environmental solutions that can be applied not only in higher education institutions, but also by the wider community.
