Abstract

Biofloc is one of the advances in fish farming technology with the main principle of recycling nutrients into the culture system. Biofloc application has been widely used in freshwater aquaculture systems, but in seawater aquaculture systems it is still very limited. This study evaluated the application of bioflocs with different bacterial sources, EM4_Fishery and Nitrobac, on the growth and survival of White Snapper (Lates calcalifer) and the water quality of the aquaculture environment. This study used a completely randomised design (CRD) with three replications. A total of 19 White Snapper fish with an average weight of 6.86±0.17 g/L were put into each 14-day-old biofloc and control. Feeding was 2% of total body weight with a frequency of once a day (09.00 am). The results showed that during the experimental period, the weight of White Snapper fish decreased variably in both treatments and controls. The survival rate of White Snapper fish in the Nitrobac bacteria treatment tended to be higher than in the EM4_Fishery bacteria, but both were lower than the control with a tendency for large fish to survive longer than small fish. Concentrations of ammonia, nitrite and nitrate in the treatments at the beginning of the experiment were higher than the control but tended to decrease with the length of rearing. DO values tended to increase in the treatments compared to the control, while DO values tended to increase in the treatments compared to the control. These findings revealed that the Nitrobac as a source of biofloc bacteria in marine White Snapper culture is more effective than EM4_Fisheries, but requiring further experiments with some concern on individual fish size greater than 7 g and the biofloc older than two weeks is recommended.

Abstract

Rumput laut merupakan salah satu sumber daya hayati laut yang memiliki nilai strategis sebagai bahan pangan, energi alternatif, serta agen ekologis dalam menjaga keseimbangan lingkungan. Potensi ini sangat relevan diperkenalkan kepada generasi muda, khususnya siswa SMA, untuk membangun kesadaran sains dan lingkungan berbasis sumber daya lokal yang melimpah di wilayah Maluku. Edukasi berbasis rumput laut diharapkan dapat memperkuat literasi ekologis sekaligus menumbuhkan sikap peduli lingkungan pada peserta didik. Kegiatan ini bertujuan untuk meningkatkan pemahaman siswa kelas XI IPA 1 SMA Negeri 3 Ambon mengenai manfaat dan peluang pemanfaatan rumput laut dalam mendukung ketahanan pangan, energi terbarukan, serta mitigasi perubahan iklim. Metode pelaksanaan dirancang secara edukatif melalui tahap persiapan, sosialisasi tatap muka, dan evaluasi dengan instrumen pre-test dan post-test. Materi disampaikan secara interaktif menggunakan media visual berupa slide, infografis, dan diskusi kontekstual. Hasil kegiatan menunjukkan adanya peningkatan signifikan dalam pemahaman siswa terhadap definisi, fungsi ekologis, dan pemanfaatan aplikatif rumput laut. Sebelum kegiatan, mayoritas siswa hanya memahami rumput laut sebatas organisme laut yang bermanfaat secara umum, sedangkan setelah sosialisasi terjadi peningkatan pemahaman mendalam terkait fungsi ekologis sebagai penyerap karbon, penyaring logam berat, hingga potensi pengembangan bioenergi dan bioplastik. Siswa juga menunjukkan antusiasme tinggi, tercermin dari partisipasi aktif dalam diskusi dan refleksi akhir kegiatan. Dengan demikian, kegiatan ini terbukti efektif dalam meningkatkan literasi sains, kesadaran ekologis, serta wawasan siswa mengenai potensi rumput laut sebagai solusi pangan dan energi berkelanjutan.
