Abstract

Accuracy of rainfall data is very important in hydrological analysis, especially in areas with limited data such as Labuan Bajo City, Indonesia. Global climate data generated from satellite observations and assimilation products, which are freely available, have great potential for use in data scarce areas. However, this data needs to be evaluated to measure its accuracy in rainfall estimates. This research aims to evaluate the accuracy of eight global rainfall data products, namely Global Precipitation Measurement (GPM), Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN), Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks – Cloud Classification System (PERSIANN-CCS), Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks - Climate Data Record (PERSIANN-CDR), Precipitation Data Integration and Retrieval - Now (PDIR-Now), European Reanalysis for the 5th Generation (ERA5), European Reanalysis for the 5th Generation Land (ERA5-LAND), and Climate Hazards Group InfraRed Precipitation with Station Data (CHIRPS) at two temporal scales: monthly and 15-daily. Evaluation is carried out using an assessment matrix which includes Root Mean Square Error (RMSE), Nash-Sutcliffe Efficiency (NSE), correlation (r), and Relative Bias (RB). The evaluation results show that on a monthly scale, ERA5, PERSIANN, and GPM provide the best results, with ERA5 being the top. On a 15-daily scale, ERA5 also shows the best performance, followed by GPM and ERA5-LAND. These findings confirm that ERA5 is the main choice for monitoring rainfall in Labuan Bajo City, which is very important for water resource management in areas with limited direct observation data.

Abstract

Abstrak: Pelatihan pembuatan greenhouse dan instalasi hidroponik sangat penting untuk meningkatkan pemahaman dan keterampilan praktis masyarakat dalam memanfaatkan lahan secara optimal, mendukung ketahanan pangan, serta mendorong penerapan teknologi pertanian modern yang ramah lingkungan. Pelatihan pembuatan greenhouse dan instalasi hidroponik ini bertujuan untuk meningkatkan keterampilan teknis dan pemahaman praktis petani di Kelurahan Wali dalam penerapan teknologi pertanian modern dengan metode praktik langsung. Kegiatan ini dilakukan di Kelurahan Wali, Kecamatan Langke Rembong, Kabupaten Manggarai, Nusa Tenggara Timur (NTT) sebanyak 40 orang yang tergabung dalam kelompok tani Kebun Delapan. Kegiatan ini melibatkan ceramah, diskusi, dan implementasi langsung, yang mencakup pembuatan struktur greenhouse dan instalasi sistem hidroponik. Hasil menunjukkan bahwa petani mampu mengatasi berbagai tantangan teknis dan memahami pentingnya pengaturan lingkungan mikro serta manajemen pupuk. Evaluasi yang dilakukan pada PkM ini menggunakan evaluasi hasil dengan melihat keberhasilan pembuatan greenhouse dan instalasi hidroponik. Pelatihan ini berhasil meningkatkan kompetensi petani dalam mengaplikasikan teknologi pertanian yang efisien dan berkelanjutan sebanyak 95% sekaligus produksi tanaman dengan menggunakan sumber daya air dan lahan secara efisien.Abstract: Training on greenhouse making and hydroponic installation is very important to improve the understanding and practical skills of the community in utilizing land optimally, supporting food security, and encouraging the application of modern agricultural technology that is environmentally friendly. This training on greenhouse construction and hydroponic installation aims to improve the technical skills and practical understanding of farmers in Wali Village in the application of modern agricultural technology with hands-on methods. This activity was carried out in Wali Village, Langke Rembong District, Manggarai Regency, East Nusa Tenggara (NTT) for 40 people who are members of the Kebun Eight farmer group. The activity involved lectures, discussions, and hands-on implementation, which included the creation of a greenhouse structure and the installation of a hydroponic system. Results showed that farmers were able to overcome various technical challenges and understood the importance of micro-environmental settings and fertilizer management. The evaluation conducted in this PkM used outcome evaluation by looking at the success of greenhouse construction and hydroponic installation. This training succeeded in increasing farmers' competence in applying efficient and sustainable agricultural technology by 95% as well as crop production by using water and land resources efficiently.
