Penelitian ini berjudul “Analisis Kandungan Protein Oyster (Crassostrea sp.) di Kawasan Laguna Segara Anakan Cilacap. Laguna Segara Anakan memiliki peran ekologis penting bagi berbagai biota perairan, salah satunya yaitu oyster (Crassostrea sp.). Oyster (Crassostrea sp.) memiliki kandungan protein tinggi yang dapat dijadikan sebagai sumber nutrisi. Kandungan protein pada oyster (Crassostrea sp.) dapat berbeda-beda dipengaruhi oleh kondisi fisika-kimia air. Tujuan penelitian ini untuk menganalisis kandungan protein, mengetahui parameter fisika-kimia air, dan menganalisis hubungan faktor fisika-kimia air terhadap kandungan protein oyster (Crassostrea sp.) di Kawasan Laguna Segara Anakan Cilacap. Metode penelitian yang digunakan adalah metode survei. Penentuan kandungan protein dianalisis menggunakan metode Kjedahl. Hasil penelitian menunjukkan kandungan oyster (Crassostrea sp.) berkisar antara 18,57±1,13 - 20,02±1,37%. Parameter fisika-kimia air seperti suhu, salinitas, pH, DO (Dissolved Oxygen), kecerahan dan kedalaman berada pada batas toleransi. Kandungan protein oyster (Crassostrea sp.) memiliki hubungan yang sedang dengan parameter kedalaman (r= 0,455), sedangkan salinitas (r= -0,234 dan pH (r= -0,227) hubungannya lemah, serta DO (Dissolved Oxygen) (r= -0,062); suhu (r= -0,024); dan kecerahan (r= 0,015) hubungannya sangat lemah dengan kandungan protein oyster (Crassostrea sp.).

The study entitled “Analysis Protein Content of Oyster (Crassostrea sp.) in Segara Anakan Lagoon Cilacap. Segara Anakan Lagoon has an important ecological role for various aquatic biota, one of which is oyster
(Crassostrea sp.). Oyster (Crassostrea sp.) has a high protein content that can be used as a source of nutrition. The protein content in oyster (Crassostrea sp.) can vary influenced by the physical-chemical conditions of water. The purpose of this study was to analyze the protein content, determine the physical-chemical parameters of water, and analyze the relationship of water physical-chemical factors to the protein content of oyster (Crassostrea sp.) in the Segara Anakan Lagoon Cilacap. The research method used is the survey method. Determination of protein content was analyzed using the Kjedahl method. The results showed the content of oyster (Crassostrea sp.) ranged from 18.57±1.13 - 20.02±1.37%. Physical-chemical parameters of water such as temperature, salinity, pH, DO (Dissolved Oxygen), brightness, and depth are still at the tolerance limit. The protein content in oyster (Crassostrea sp.) has a moderate relationship with the depth parameter (r= 0.455), while salinity (r= 0.234) and pH (r= 0.227) the relationship is weak, and DO (Dissolved Oxygen) (r= 0.062); temperature (r= 0.024); and brightness (r= 0.015) very weak relationship with protein content of oyster (Crassostrea sp.).
