چکیده

Rumput laut hijau Ulva sp. dapat dimanfaatkan sebagai bahan baku pembuatan garam rendah natrium tinggi kalium dari rumput laut. Peningkatan kandungan ditambahkan dengan alami salah satunya tanaman genjer ( Limnocharis flava ). Tujuan penelitian ini adalah mendapatkan komposisi kimia tepung dan aktivitas antioksidan ekstrak lactuca L . Penelitian terdiri beberapa tahapan meliputi preparasi U. genjer, ekstraksi genjer. Parameter yang dianalisis kimia, logam berat, mineral, fitokimia, antioksidan. Hasil menunjukkan tertinggi pada U yaitu karbohidrat nilai sebesar 43,55±0,25% 53,11±0,23%.
