Exploring Sustainable Waste Management Practices in Bali
upskill Udayana's Excursion Postgraduate of Tropical Coastal Ecology and Community-Based Management Winter Semester 2023
Day 1: Tackling Waste Management Challenges at TPS3R Ketewel
The first day commenced with a site visit to TPS3R Ketewel, where the Upskill students, alongside their Udayana counterparts, were welcomed by the village head, Pak Putu Widya Kusuma Negara. Led by Pak Ketut Suwarnaya, the brains behind the waste management initiative, the tour showcased the village's utmost commitment to sustainable waste practices.
Pak Ketut's tireless efforts, spanning eight months of community engagement, resulted in the enrollment of 500 households (approximately 2,000 individuals) in the organic waste management program. Families paid a nominal monthly fee of 20,000 IDR, ensuring their organic waste was not only responsibly disposed of but also utilized in producing high-quality organic compost.
The meticulous process involved sorting and grinding organic waste, utilizing a unique Okashi system for cost-effective composting. The 60-70-day process, monitored rigorously, resulted in the creation of organic compost, sold at 7,000 IDR per kilogram. Pak Ketut's commitment to waste management extended beyond Ketewel, with 13 additional TPS3R sites in surrounding villages.
Day 2: A Deep Dive into Waste Management Initiatives in Gianyar
The second day featured a double-site visit to Padang Tegal TPS3R and Griya Luhu Waste Bank in Gianyar. The students were joined by industry experts and Udayana's Professor Dwipayanti to give them further insights about environmental practice and enhance the whole educational experience.
Site 1: Padang Tegal TPS3R
The morning session began with an in-depth tour led by Anggi Giovanda from the management team. The facility, operational since 2012, focused on segregating waste from 673 households and 700 businesses. The waste, collected twice daily, underwent a meticulous composting process, emphasizing aerobic composting for its environmental benefits. Anggi demonstrated the composting boxes and explained the duration of the composting timeline (around 3 to 4 months), ensuring the final product was rich, odor-free soil. The facility's achievements, including winning first place from the Ministry of Public Health Governance, highlighted the positive impact of collaborative efforts between administrative and traditional villages.
Site 2: Griya Luhu Waste Bank
The afternoon session at Griya Luhu Waste Bank, presented by Alfina Febrilia Arantika, showcased a community-driven initiative that evolved from waste awareness campaigns to a full-fledged waste bank. The bank, established in 2017, adapted to the challenges of COVID-19 by introducing a digital waste bank application and supporting community engagement through incentives and education.
Key Takeaways and Future Implications
Our study program not only provided a firsthand look into Bali's waste management landscape but also offered invaluable insights into community-driven initiatives. The experiences shared by waste management pioneers like Pak Ketut Suwarnaya and the teams at Padang Tegal TPS3R and Griya Luhu Waste Bank serve as inspiration for future endeavors in combating the global challenge of waste management. As we return with a wealth of knowledge and a broader perspective on waste management, the hope is that their experiences will fuel positive change in their academic pursuits and professional endeavors. The excursion program stands as a testament to the transformative power of education and community collaboration in addressing environmental threats and building a sustainable future.
