Abstract

Ekonomi biru merupakan pendekatan berkelanjutan yang memanfaatkan sumber daya kelautan untuk meningkatkan kesejahteraan ekonomi dan melestarikan lingkungan. Penelitian ini bertujuan mengoptimalkan potensi ekonomi biru melalui pengolahan limbah perikanan menjadi pakan ikan, yang dapat mengurangi dampak lingkungan dan meningkatkan kesejahteraan masyarakat pesisir. Metode pengabdian yang digunakan melibatkan persiapan, pelaksanaan, dan evaluasi hasil. Tahap persiapan mencakup koordinasi dengan mitra dan pemerintah desa, serta persiapan peralatan dan bahan. Pelaksanaan dilakukan melalui pelatihan dan praktek langsung pembuatan pakan ikan menggunakan bahan baku lokal. Hasil kegiatan menunjukkan bahwa kelompok budidaya di Desa Tukak berhasil memproduksi pakan ikan secara mandiri, dengan biaya produksi yang jauh lebih rendah dibandingkan pakan komersial. Pakan yang dihasilkan digunakan untuk budidaya ikan bandeng dan udang windu, yang secara signifikan mengurangi ketergantungan pada pakan komersial. Kegiatan ini berhasil meningkatkan kemandirian dan efisiensi produksi budidaya ikan, serta membuka peluang ekonomi baru yang berkelanjutan bagi masyarakat pesisir. Dukungan dari pemerintah dan mitra lokal diharapkan dapat memastikan keberlanjutan program ini di masa depan.

Abstract

Water is a fundamental human need that must be available to support daily activities. However, ensuring the availability of clean water remains a significant challenge for both communities and water providers, whether managed by the private sector or the government. One effective approach to ensuring the availability of clean water is accurately predicting the water discharge from raw water sources. The results of these predictions can be used to map the potential for water availability and identify areas with water deficits. This study focuses on predicting water discharge in the Kolong ST 12 reservoir, located in the Sungailiat District of Bangka Regency. The Singular Spectrum Analysis (SSA) method is used for prediction. The aim of this study is to evaluate the accuracy of the SSA method as a prediction model. The results show that predictions made using the SSA method are quite accurate, as evidenced by the Mean Absolute Percentage Error (MAPE) values of 46.68% for in-sample data and 35.54% for out-of-sample data. These MAPE values indicate that the SSA method has an accuracy of 53.32% for in-sample predictions and 64.46% for out-of-sample predictions. Parameter selection and data preprocessing processes affect the accuracy of the SSA method prediction results. The results of this study indicate that the SSA method has the potential to be developed into an accurate prediction model in analyzing water discharge data for optimal water resources management. The implications of this study are that the findings can assist the government and relevant stakeholders in water management. This study provides strategic information for policy planning to support food security programs and prevent water shortages through well-planned distribution.
