Abstract

.  Cinnamon leaves have properties as lowering blood sugar levels, inhibiting bacterial growth. Cinnamon traditional medicine contains the largest component of chemical substances, namely cinnamic alcohol, coumarin, cinnamic acid, sinamaldehyde, anthocinin and essential oils with sugar, protein, simple fat, pectin and others. Furthermore, it is said that cinnamon has antimicrobial, antifungal, antiviral, antioxidant, antitumor, blood pressure lowering, cholesterol and has low fat compounds. The dominant polyphenolic compound in cinnamon leaves is from the aldehyde group, which has insulin-like activity and antioxidant activity.  This study aims to determine the compounds contained in cinnamon leaves and antibacterial and toxicity testing of cinnamon leaves (Cinnamomum burmanni) was carried out to determine the effect on the mortality rate of Artemia salina Leach larvae. The results of toxicity testing of cinnamon leaf extract are known to be non-toxic and have an LC50 value of 128.6 ppm.  From the results of antibacterial tests of cinnamon leaf extracts with methanol, ethyl acetate and N hexanes solvents, it is known that the highest inhibition is in leaf extracts using methanol solvents with a yield of 12% and inhibition of 5 mm, while phytochemical tests of cinnamon leaf water extracts contain Alkaloids, tannins, saponins and flavonoids, triterpenoids and flavonoids.

Abstract

Caulerpa racemosa merupakan salah satu komoditas baru yang memiliki potensi tinggi dalam bidang perikanan. Selama ini, pemanfaatannya masih bersifat ekstraktif, yakni dengan cara pengumpulan langsung dari wilayah pesisir, sehingga budidayanya sangat prospektif untuk dikembangkan secara berkelanjutan. Penelitian ini bertujuan untuk menganalisis pertumbuhan panjang stolon, panjang ramuli, dan berat total C. racemosa pada empat kedalaman tanam berbeda, yaitu 1 meter, 2 meter, 3 meter, dan dasar perairan (kontrol). Penelitian dilaksanakan di Keramba Jaring Apung Politeknik Perikanan Negeri Tual selama 30 hari, dari 23 Desember 2024 hingga 23 Januari 2025. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan tiga ulangan untuk setiap perlakuan. Pengukuran panjang stolon, ramuli, dan parameter kualitas air dilakukan setiap tiga hari, sementara pengukuran berat dilakukan pada awal dan akhir penelitian. Data dianalisis menggunakan analisis keragaman (ANOVA). Hasil penelitian menunjukkan bahwa perlakuan pada kedalaman 3 meter (perlakuan C) menghasilkan panjang stolon tertinggi sebesar 35,6 cm dan panjang ramuli tertinggi sebesar 14,7 cm. Sementara itu, berat total tertinggi diperoleh pada perlakuan kontrol (dasar perairan) sebesar 1,9 kg.
