Abstract
Dampak pemanasan global yang meningkat tiap tahun mengakibatkan peningkatan suhu dan pengasaman laut. Peningkatan suhu dan pengasaman laut menyebabkan gangguan metabolisme organisme laut, salah satunya keong lola (Rochia nilotica). Bermacam respon fisiologis dan perilaku dari R. nilotica diakibatkan oleh kenaikan suhu dan pengasaman laut. Namun, pemanfaatan R. nilotica sebagai bioindikator belum banyak dilakukan. Tujuan penelitian ini untuk pengembangan cangkang R. nilotica sebagai bioindikator dengan menghubungkan parameter suhu dan pH melalui morfometrik cangkang (Panjang (SL), Spire (Sp), Whorl (Wh), Lebar (BWL), dan Berat (W)). Pengukuran morfometri menggunakan jangka sorong, timbangan digital, sedangkan warna dan rasio whorl dengan software ImageJ. Data seri suhu dan pengasaman laut dari NASA Ocean Color dan studi literatur dianalisis dengan software SeaDAS. Korelasi antara suhu dan pH dengan parameter morfometri dinalisis menggunakan scatter plot program Ms. Excel. Hasil penelitian menunjukkan bahwa perubahan suhu & pH yang luas mempengaruhi morfometri. Nilai r ΔT dengan morfometri (±0.4 - 0.46) di lebar & berat. Sementara nilai r ΔpH (± 0.34 - 0.36) di panjang & spire. Sehingga cangkang R. nilotica berpotensi sebagai bioindikator pemanasan global pada perubahan suhu.

The impact of global warming, which increases every year, has resulted in an increase in ocean temperature and acidification. Increased temperature and ocean acidification cause metabolic disturbances in marine organisms, one of which is Lola snails (Rochia nilotica). Various physiological and behavioral responses of R. nilotica are caused by increased ocean temperature and acidification. However, the utilization of R. nilotica as a bioindicator has not been widely carried out. The purpose of this study was to develop R. nilotica shells as bioindicator by correlating temperature and pH through shell morphometrics (Length (SL), Spire (Sp), Whorl (wh), Width (BWL), and Weight (W)). Morphometric measurement used a caliper, a digital scale, while color and whorl ratio with ImageJ software. Ocean temperature and acidification data series from NASA Ocean Color and literature studies were analyzed with SeaDAS software. The correlation between temperature and pH with morphometric parameters was analyzed using a scatter plot of Ms. Excel program. The results showed that wide changes in temperature and pH affected morphometry. The r ΔT value (±0.4 - 0.46) in width & weight. Meanwhile the r ΔpH value (± 0.34 - 0.36) in length and spire. Therefore, R. nilotica shell has the potential to be a bioindicator of global warming due to temperature changes.
