Blue Carbon Potential of Salt Marshes in Kulon Progo for Climate Change Mitigation in Indonesia

Tue, 29 Apr 2025 00:00:00 +0000

Salt marshes along the coast of Kulon Progo in Yogyakarta can act as blue carbon storage facilities to achieve the climate change mitigation goals outlined in Indonesia’s Nationally Determined Contributions (NDC) for 2030. Three villages in Temon District became the location of this research: Glagah, Palihan, and Jangkaran Villages. A mixed-methods approach was employed in this research, encompassing direct field observation, soil and vegetation analysis in their capacity as carbon storage, and interviews with individuals in the 3 villages. The results of the analysis showed that there was a small amount of carbon content in various locations in the 3 villages. Mangroves and pine trees, particularly those growing around swamps, play a significant role in carbon absorption. However, this study revealed a decrease in the potential of salt marsh land due to changes in land use to Yogyakarta International Airport (YIA) and the surrounding city planning. As a result, carbon storage capacity is reduced, and carbon emissions from land that has changed function are higher. The study also sees the importance of strengthening government policies and regulations and increasing community participation in salt marsh conservation through village-based programs such as the Climate Village Program (PROKLIM) and Resilient Coastal Village. The study concludes that through salt marsh conservation, the potential for blue carbon becomes more significant, which also requires collaboration between stakeholders.

This study aims to develop a reminder application system for patients with hypertension and diabetes mellitus (DM) to improve medication adherence and health monitoring. Hypertension and diabetes are non-communicable diseases whose prevalence continues to rise in Indonesia, with Puskesmas Ngaglik 1 as the study location showing low patient compliance with the chronic disease management program (Prolanis). Using the User Centered Design (UCD) method, this research involves users at every stage of system development, from problem identification, literature review, to prototype creation. The results indicate that the developed application can assist patients in remembering their medication schedules, routine check-ups, and exercise, as well as providing emergency features to enhance interaction between patients and Prolanis staff. Prototype evaluation was conducted through two iterations, demonstrating that the resulting system meets user needs. Users say that the system built can help in the Prolanis program and improve discipline in patients.

Potensi Limbah Hasil Pertanian Padi menjadi Sumber Bioenergi melalui Konsep Biorefineri dengan Pendekatan P-Graph dan Analisis Ekonomi Teknik di Kabupaten Sleman, Yogyakarta

Agricultural waste, especially from rice such as straw, husks, and bran, is one of the abundant biomasses in Indonesia, particularly in Sleman Regency, DI Yogyakarta, which is one of the regions with the highest rice productivity. The potential of rice waste can be used as a source of bioenergy using a biorefinery approach. The concept of a biorefinery is the processing of biomass that produces various products and by-products to achieve sustainability. The analysis of the potential of this biomass waste was conducted using p-graph and techno-economics. Based on the optimization analysis with the p-graph, the optimal and maximal solutions were obtained after running the superstructure flow. The optimal solution indicates that the transesterification process of rice bran into biodiesel is more feasible with a profit of 9000 USD/year. For the maximal solution, an economic analysis was conducted because the products generated are more numerous, allowing for the implementation of a biorefinery approach. The results of the techno-economic analysis show that the production of several bioenergy products will fully recoup the initial investment by the 8th year. The IRR value obtained is 21.7%, while the MARR (Minimum Attractive Rate of Return) is 15%, indicating that the investment is viable for funding. Additionally, from an environmental perspective, the use of biomass waste for bioenergy production has a positive impact by reducing greenhouse gas emissions and pollution, as well as enhancing soil fertility through the application of biochar. From a social perspective, community-based bioenergy production can increase income, improve community welfare, enhance bioenergy production, and support energy independence and sustainability.
