Abstract

Penelitian ini bertujuan untuk menganalisis pola konsentrasi klorofil-a dari citra satelit Aqua MODIS pada musim timur, menganalisis berbagai parameter yang memberikan dampak dominan terhadap nilai klorofil-a serta melakukan validasi nilai konsentrasi klorofil-a dari citra satelit Aqua MODIS terhadap nilai konsentrasi klorofil-a data in situ. Distribusi klorofil-a di perairan Selat Madura pada Musim Timur diselidiki berdasarkan data citra satelit Aqua MODIS bulan Juni-September 2013 serta pengukuran klorofil-a in situ pada bulan September 2013 menggunakan metode spektrofotometri.Hasil penelitian menunjukkan bahwa parameter oseanografi yang berkaitan dengan persebaran klorofil-a di perairan Selat Madura diantaranya adalah suhu permukaan laut, kecerahan, oksigen terlarut dan kecepatan arus. Sebaran klorofil-a pada musim timur berkisar antara 0,022317 – 1,561958 mg/L dengan puncak sebaran tertinggi di bulan Juli yaitu berkisar antara 0,102566 – 1,561958 mg/L. Setelah dilakukan uji validasi terhadap hasil analisa citra dan in situ menggunakan uji regresi, diperoleh nilai R square sebesar 80,14% sehingga dapat disimpulkan hasil analisa citra satelit berpengaruh besar terhadap hasil analisa in situ sebesar 80% dengan rata-rata konsentrasi klorofil-a hasil analisa citra 1,127181 mg/L dan rata-rata konsentrasi klorofil-a in situ 1,195664 mg/L. Kedua data memiliki nilai rata-rata pada rentang 1-1,5 mg/L sehingga dapat disimpulkan perairan Selat Madura memiliki kandungan klorofil-a yang tinggi.

Abstract

The aim of this study is to isolate the antioxidative peptide from Spirulina platensis. Peptide was obtained by proteolytic digestion, ultrafiltration, fractionation by RP-HPLC, identified by LC-MS/MS—MASCOT Distiller and measured its antioxidant activity by DPPH (2.2-Diphenyl-1-picrylhydrazyl) assay. Results showed that thermolysin was the most effective enzyme to digest this algae. The active peptide Phe-Ser-Glu-Ser-Ser-Ala-Pro-Glu-Gln-His-Tyr (m/z 1281.51) was identified and synthetized, which exhibited 45.98 ± 1.7% at concentration 128.15 µg/mL. Therefore, S. platensis is indicated as a potential therapeutic source for combating oxidative stress.
