Pengelolaan sumber daya pesisir yang tidak berbasis lingkungan dapat menyebabkan terjadinya penurunan kualitas lingkungan pesisir, seperti masuknya cemaran zat organik ataupun zat anorganik ke dalam badan perairan. Salah satu bentuk cemaran yang sangat berpotensi hadir dalam lingkungan perairan laut adalah logam berat seperti Kadmium (Cd) sebagai akibat dari aktivitas manusia di dekat wilayah pesisir. Keberadaan logam ini sangat berpotensi membahayakan biota laut seperti kerang-kerangan, kepiting, udang yang hidupnya di daerah pesisir. Penelitian ini bertujuan untuk menentukan kandungan logam Cd dalam daging kerang darah (Anadara granosa) dan sedimen pada habitat kerangnya serta kelayakannya untuk dikonsumsi berdasarkan nilai ambang batas cemaran Cd yang disyaratkan. Pengambilan sampel dilaksanakan pada bulan Juni 2020 menggunakan 2 stasiun (titik sampling), menggunakan metode purposive sampling yaitu berdasarkan jarak dari pusat aktivitas. Analisis cemaran logam berat Cd dilakukan dengan menggunakan spektrofotometer serapan atom. Hasil pengukuran menunjukkan bahwa kandungan Cd dalam daging kerang A. granosa dan sedimen pada perairan pulau Sedanau pada kedua stasiun pengambilan sampel bernilai rata-rata 1,1123 mg/kg dan 1,4551 mg/kg di statsiun 1 serta 0,0781 mg/kg dan 1.4223 mg/kg, yang masih berada di bawah ambang batas yang disyaratkan Standar Nasional Indonesia (SNI) No. 7387 tahun 2009 yaitu sebesar 1,5 mg/kg.

The maritime industry requires professionals who possess not only technical expertise but also strong ethical foundations and intercultural competence. This study offers a unique contribution by integrating Islamic values, such as humility, responsibility, and intercultural competence, into maritime cadet education, an area that remains underexplored in previous research. Unlike existing studies that primarily focus on technical or multicultural training, this research emphasizes character formation through religious and value-based education, aligning with the ethical demands of global maritime practice. This study aims to evaluate the extent to which Islamic values are embedded in cadet training programs, assess their effectiveness in shaping professional competencies, and recommend strategies for curriculum improvement. A qualitative research design was employed, involving semi-structured interviews and surveys with 20 stakeholders, including maritime professionals, lecturers, and recent graduates from Indonesian maritime institutions. Thematic analysis was used to categorize findings under the three core values. Data reliability was ensured through triangulation, expert validation of instruments, and cross-group comparison. The results reveal strong integration of Islamic values, with responsibility receiving the highest ratings, followed by humility and intercultural competence. While graduates confirmed the relevance of values in real-world settings, gaps were noted in experiential and intercultural training. The study highlights the strategic importance of values-based education in developing ethically grounded and globally competent seafarers. Recommendations include strengthening experiential learning, expanding multicultural exposure, and aligning curriculum with both industry standards and Islamic ethical principles.
