Abstract

Green mussel (Perna viridis) is oyster has high potential to be developed. A huge market demand is an important factor to optimized green mussel cultivation, there are to system that could be applied for cultivation green mussel is polyculture and monoculture. The purposed of this study is to determined growth performance of green mussel which culture in monoculture and polyculture system. Green mussel is culture in floating cage bath of monoculture and polyculture system. In polyculture system green mussel placed within seabass (Lates calcarifer). Growth performance of green mussel determined by comparizing growth in wide and body lenght using T-test to analyzed factor that assigned to growth performance used principle component analysis (PCA) to environment factor such as Total Amonia Nitrogen (TAN), Total Organic Matters (TOM), Total Suspended Solid (TSS) and phytoplankton both in polycultured and monocultured system. The result of this research was shown that growth in this significant shown from third place where sample collected at 0-100 in depth The results showed that this significant growth was shown from the third place where the samples were collected at 0-100 in depth and the second place where the samples were collected at 100-150 in depth. This is caused by availability of feed source such as TOM and phytoplankton thy driven by sea current. The significant value shown by growth in wide of mussel shell at 100-150 cm in depth.

Abstract

 Guru memiliki peranan sentral dalam pembelajaran PPKn untuk membentuk karakter dan kesadaran bernegara, namun konsep hak dan kewajiban pada siswa kelas III SD sering kali dirasakan abstrak dan sulit dipahami, sehingga memerlukan strategi pembelajaran yang konkret dan interaktif. Tujuan penulisan ini adalah membahas urgensi penerapan kombinasi demonstrasi gerak dan kuis interaktif untuk meningkatkan pemahaman hak dan kewajiban siswa. Metode telaah yang digunakan adalah pendekatan deskriptif berdasarkan hasil pengamatan dan pengalaman penulis selama pelaksanaan peer teaching. Analisis menunjukkan bahwa demonstrasi gerak efektif meningkatkan minat dan keterampilan berpikir karena siswa dapat mengamati proses secara langsung, sementara kuis interaktif seperti Wordwall terbukti meningkatkan motivasi dan membuat pengulangan materi menjadi menyenangkan. Implikasinya adalah rekomendasi untuk mengadopsi strategi pembelajaran inovatif yang konkret dan interaktif di tingkat sekolah dasar guna mengatasi kesulitan belajar konsep abstrak dan meningkatkan partisipasi siswa dalam PPKn.
