Abstract:
Abstrak Selama beberapa tahun terakhir pemantauan dengan citra satelit menunjukkan kondisi garis pantai Surabaya mengalami perubahan signifikan, hal ini dikarenakan fenomena erosi, akresi dan antropogenik. Fenomena tersebut dapat menjadi ancaman terhadap lingkungan pantai Surabaya dimana masyarakat pesisir (nelayan) bergantung langsung terhadap hasil pantai dan tambak. Penelitian ini bertujuan untuk mengetahui adanya dampak sosial ekonomi akibat perubahan tutupan lahan khususnya area tambak. Metode yang dilakukan adalah penginderaan jauh dengan analisis metode maximum likelihood dan metode statistik deskriptif. Hasil penelitian menunjukkan bahwa pada tahun 2011-2017, area tambak mengalami penurunan sebesar 8,66 km2 .Berkurangnya area tambak dan jumlah produksi ikan tambak (air tawar), tidak memberikan dampak signifikan terhadap nilai Produk Domestik Regional Bruto (PDRB) kategori A. Hal ini dikarenakan produksi ikan tidak hanya berasal dari tambak (air tawar) tetapi juga dari produksi ikan laut. Nilai PDRB kota Surabaya selama 3 tahun terakhir mengalami naik turun dikarenakan dampak pandemi COVID 19. Namun pada tahun 2021, nilai PDRB kota Surabaya mulai menunjukkan dampak positif. Perlu adanya pendampingan dari pemerintah terhadap nelayan tambak dan aturan pengelolaan kawasan pesisir. Diharapkan kawasan tambak dapat secara optimal memproduksi ikan air tawar dengan tujuan memberikan tambahan nilai lebih terhadap PDRB kota Surabaya kedepannya.

Abstract Over the last few years, satellite imaging data shows that the condition of coastal lines in Surabaya has significantly changed. Several factors can contribute to this issue, such as erosion, accretion, and anthropogenic phenomena. These factors are a threat to the environment of Surabaya because many coastal communities (fishermen) are relying on beach and pond products. This research aims to better understand the socioeconomic effect of changes in land cover, especially in pond areas. To collect data, the research used remote sensing tools. The data were then analyzed using maximum likelihood and descriptive statistics methods. Results indicated that between 2011 – 2017, the pond areas declined by 8.66 km2. However, the decline of the pond areas and pond fish quantities (freshwater fish) does not have a significant impact on the value of the Gross Regional Domestic Product (GRDP) category A. One of the reasons is that fish production is not only taken from the pond (freshwater) but also from the sea. The value of Surabaya’s GRDP in the last three years is volatile due to the Covid-19 outbreak. However, in 2021, the GRDP has shown an increase. The government should play their roles by providing assistance to pond fishermen and regulating the management of coastal areas. Hopefully, pond areas can increase freshwater production in order to give an additional contribution to the GRDP of Surabaya.
