Abstract

The research aims to determine the phytochemical content such as phenolics, flavonoids, tannins, saponins, alkaloids, steroids, and triterpenoids found in the seaweed G. verrucosa. Seaweed G. verrucosa taken from the waters of North Sulawesi, Nain Village, North Minahasa, was extracted by maceration for 24 hours at room temperature, repeated 3 times using 96% ethanol solvent. The analysis in this study consisted of seven test parameters such as phenolic compounds, flavonoids, tannins, saponins, steroids, triterpenoids, and alkaloids. The results of the analysis showed that the secondary metabolites of G. verrucosa contained phytochemical compounds such as phenols, flavonoids, tannins, saponins, steroids, and alkaloids, and no triterpenoid compounds were found. It was concluded that G. verrucosa which grows in the waters of North Sulawesi, Nain Village, can function as functional food, and medicine because it has natural bioactive compounds. Keywords: Phytochemical content, Gracilaria verrucosa, secondary metabolites Abstrak Penelitian bertujuan mengetahui kandungan fitokimia seperti fenol, flavanoid, tanin, saponin, alkaloid, steroid, dan triterpenoid yang terdapat pada rumput laut G. verrucosa.  Senyawa metabolit sekunder yang umum terdapat pada tanaman adalah senyawa terpenoid, alkaloid, fenolik, streroid, saponin, tannin. Rumput laut G. verrucosa yang di ambil dari perairan Sulawesi Utara Desa Nain Minahasa Utara di ekstraksi dengan cara maserasi selama 24 jam pada suhu ruang di ulangi sebanyak 3 kali menggunakan pelarut etanol 96 %. Analisis pada penelitian ini terdiri dari tujuh parameter pengujian seperti senyawa fenol, flavonoid, tanin, saponin, steroid, triterpenoid dan alkaloid. Hasil analisis menunjukan bahwa kandungan metabolit sekunder dari G. verrucosa mengandung senyawa fitokimia seperti fenol, flavonoid, tanin, saponin, steroid, alkaloid dan tidak ditemukan adanya senyawa triterpenoid. Hal ini disimpulkan bahwa G. verrucosa yang tumbuh di perairan Sulawesi utara Desa Nain dapat berfungsi sebagai pangan fungsional, obat-obatan karena memiliki senyawa bioaktif alami. Kata kunci: Kandungan fitokimia, Gracilaria verrucosa, metabolit sekunder

Abstract

The purpose of this study is to determine the pH level and macro and micronutrient content in the soil of the mangrove forest area in Bunaken Marine Park, Meras Village, Wori District, North Sulawesi Province. Soil samples were collected from both dry soil and waterlogged soil. The samples were then taken to the laboratory for analysis of macro- and micronutrients as well as pH levels. The analysis used includes: Nitrogen (N) analysis following SNI 7763:2018, section 6.6.1; Phosphorus (P) analysis following SNI 7763:2018, section 6.7; Elements K, Ca, Fe, Mg, Cu, Zn, B, Mn, and Mo analyzed using IK-1.13 Method for Determination of Metal Minerals in Food and pH analysis using SNI 01-2891-1992. The research results show that the pH values of dry and waterlogged soil are 6.67 and 6.0, respectively, which are considered good categories. The macro-nutrient analysis results for N, P, K, and Mg are classified as good because they exceed the minimum requirements set by SNI 7763:2024. However, the Ca element is classified as not good as it exceeds the maximum limit specified by SNI 7763:2024. For micro-nutrients, Fe (Iron) content is 13,682 ppm, which falls under the good category since it is below the maximum limit of 15,000 ppm as per SNI 7763:2024. Zn (Zinc) content is 0.4807 ppm, which is also considered good, as it does not exceed the maximum limit of 5,000 ppm as per SNI 7763:2024. Keywords: Meras Mangrove Forest, Nutrients, pH. Abstrak Tujuan dari penelitian ini adalah untuk mengetahui kandungan pH, unsur hara makro dan mikro pada tanah kawasan hutan mangrove taman laut Bunaken desa Meras kecamatan wori propinsi sulawesi utara. Pengambilan sampel tanah diambil pada tanah yang kering dan tanah yang tergenang air. Sampel tanah dibawa ke laboratorium untuk dianalisa unsur hara makro, mikro dan pH. analisa yang digunakan adalah Analisa N dengan SNI 7763:2018 butir 6.6.1. Analisa P dengan SNI 7763:2018 Butir 6.7. unsur K, Ca Fe dan Mg, Cu, Zn, B, Mn dan Mo dengan metode IK-1.13 Penentuan Mineral Logam pada Pangan dan Non Pangan. Dan pH dengan metode SNI 01-2891-1992. Hasil penelitian bahwa nilai pH tanah kering dan tergenang adalah pH 6,67 dan 6,0. Termasuk kategori baik.  Hasil Analisa unsur makro yaitu N, P, K dan Mg adalah adalah katgori baik karena melebihi syarat minimum dari SNI 7763:2024, sedangkan nilai Ca kategori tidak baik karena melebihi batas maksimum SNI 7763:2024.  Unsur mikro Fe adalah 13682 ppm termasuk kategori baik karena mempunyai nilai lebih rendah dari 15.000 ppm sebagai batas maksimum dari SNI 7763:2024. Unsur Zn adalah 0.4807 ppm termasuk kategori baik karena tidak melebihi batas maksimum 5.000 ppm sebagai batas maksimum dari SNI 7763:2024. Kata kunci: Hutan Mangrove Meras, unsur hara, pH
