IntisariPenerapan Teknologi Modifikasi Cuaca (TMC) di Indonesia terus mengalami perkembangan. Tidak hanya untuk menambah curah hujan, belakangan TMC kerap dijadikan solusi yang menjanjikan untuk mengurangi curah hujan si suatu daerah. Melalui konsep Metode Kompetisi dan Metode Jumping Process, curah hujan di suatu daerah dapat dikurangi intensitasnya. Penerapan TMC untuk mengurangi curah hujan pernah diterapkan di area proyek pembangunan jalan tol-Balikpapan-Samarinda, Kalimantan Timur. Melalui evaluasi terhadap curah hujan secara spasial maupun temporal, dapat diketahui indikasi pengurangan curah hujan di wilayah tersebut. Secara spasial, aktivitas TMC mampu meredistribusi hujan di daerah upwind sehingga area pembangunan tol mendapatkan curah hujan yang lebih kecil. Menggunakan pendekatan statistik dengan membandingkan curah hujan prediksi dan curah hujan aktual, didapatkan estimasi tingkat pengurangan curah hujan selama kegiatan TMC berlangsung di kisaran nilai 40%. AbstractThe application of Weather Modification Technology (WMT) in Indonesia continues to develop. Not only to increase rainfall, but WMT is often used as a promising solution to reduce rainfall in an area. Through the concept of the Competition Method and the Jumping Process Method, the intensity of rainfall in an area can be reduced. The application of WMT to reduce rainfall has been applied in the project area of the Balikpapan-Samarinda toll road construction, East Kalimantan. Through the evaluation of rainfall spatially and temporally, it can be seen as an indication of a reduction in rainfall in the region. Spatially, WMT activity can redistribute rainfall in the upwind area so that the toll road construction area gets smaller rainfall. Using a statistical approach by comparing predicted rainfall and actual rainfall, an estimated level of rainfall reduction during the TMC activity takes place in the range of 40%.

Background: In Indonesia, the persistent occurrence of forest and land fires highlights the critical importance of early detection in determining the success of mitigation efforts. Method: This study explores several key aspects related to peatland wetness and its impact on fire prevention. Firstly, it examines the relationship between rainfall and the humidity and temperature of peatlands. Secondly, the study investigates peatland wetness as an indicator of hotspot emergence. Thirdly, the study evaluates stakeholder perceptions regarding the use of peat wetness monitoring in determining the emergency status of forest and land fire disasters. Findings: The study's results indicate that rainfall significantly influences peatland humidity, which in turn reflects the level of peat humidity and temperature. It was also found that peatlands with a Dry-Moderate humidity category can be a reliable indicator of the emergence of fire spots. The consensus among stakeholders is that monitoring peatland humidity is very important for decision-making related to emergency status. Finally, this study proposes a forest and land fire mitigation concept based on peatland humidity. Conclusion: This approach aims to reduce the risk of such fires by utilizing monitoring results to enhance preparedness, taking into consideration the current state of peatland wetness. Overall, this research underscores the importance of integrating peatland wetness monitoring into forest and land fire mitigation strategies to improve early detection and reduce the risk of fires. Novelty/Originality of this study: A study of forest fires in Indonesia links peatland wetness to fire hotspots, providing a reliable indicator for early fire detection. This is an innovative approach to forest fire prevention.

The Indonesian government's food estate program aims to achieve food security through the use and improvement of agricultural land, one of which is in peatland areas. The implementation of the food estate program in Indonesia needs to comprehensively consider environmental, economic and social aspects, so that it will not only provide benefits to the wider community, but also pay attention to the ecological functions of the peatland ecosystem. In this paper, a study is carried out on several aspects such as the availability and potential of peatlands for agriculture, the right commodities for agricultural activities on peatlands, examples of the economic benefits of peatland agriculture, and the involvement of local communities as indicators of sustainability of the food estate program. The discussion is carried out using the perspective of environmental science and FEW Nexus. The results of this study explain that the food estate program on peatlands needs to pay attention to several challenges in the environmental, social, and economic sectors. Furthermore, food estate on peatlands is also considered necessary to be implemented within the framework of the FEW Nexus in order to become a sustainable program.

Peatland wetness as an indicator of fire occurrence in Forest and Land Fires (FLFs) Prayoga, M. Bayu Rizky; Karuniasa, Mahawan; Frimawaty, Evi

Background: Peatland ecosystems play an important role in the hydrological cycle and carbon cycling. In Indonesia, peatlands store about 28.6 gigatonnes of carbon which is equivalent to 10 years of global fossil fuel emissions. Peatlands act as a water storage during wet seasons and slowly release water during dry seasons to maintain river discharges and hydrological balance. However, climate change induced prolonged drought has increased peatland dryness in recent decades which elevate the risks of unwanted peatland fires. During El Nino-induced drought in 2015, over 2.6 million hectares of forest and land burned, emitting 0.81–1.4 gigatonnes of greenhouse gasses. The extreme fires damaged biodiversity, degraded water quality and displaced thousands of locals. This study aimed to analyze peatland wetness as an indicator of fire occurrences in forest and land fires (FLFs) in Riau, Indonesia by examining the relationship between degree of peatland wetness derived from satellite imagery and hotspots data. Methods: Peatland wetness was estimated from microwave backscattering coefficients at several RadarSat synthetic aperture radar (SAR) wavelengths and cross validated with water table depth measurements from 120 monitoring wells. Hotspots data between 2015-2020 were obtained from NASA's MODIS active fire product. Findings: Preliminary results showed significant negative correlations between peatland wetness and numbers of hotspots in peatlands, with more hotspots occurring in drier peatlands compared to wetter ones. This implies that maintaining peatland hydrological functions through continuous saturation is pivotal to prevent severe peatland wildfires under future climate change. Conclusion: Conservation efforts to restore hydrological balance in degraded peatlands through re-wetting strategies are recommended. Further research utilizing machine learning algorithms to produce high-resolution peatland wetness maps can improve fire risk monitoring in peatlands. Novelty/Originality of this Study: This study introduces the novel concept of utilizing peatland wetness as a key indicator for predicting and mitigating forest and land fires in Indonesia, particularly in Riau Province. By combining peatland moisture and temperature data, the research establishes threshold values to better predict fire risks and guide timely mitigation efforts, thereby enhancing the efficiency and effectiveness of FLF response activities.
