Abstract

Analysis of the physicochemical characteristics of seaweed (Eucheuma cottonii) jam with the nipah (Nypa fruticans) sugar addition Eucheuma cottonii can be used as an ingredient for making jam because it contains carrageenan which can form a gel, in general, making jam will use granulated sugar, granulated sugar tends to only contain sucrose, in contrast to nipah sugar which has a more complex content. So that nipah sugar can be an additional ingredient in making seaweed jam replacing granulated sugar. This study aims to measure the effect of adding nipah sugar (Nypa fruticans) on the physicochemical characteristics of seaweed jam (Eucheuma cottonii) this study used a Randomized Block Design (RAK) with different concentrations of nipah sugar with 4 treatment levels A0 (50% granulated sugar), A1 (40% nipah sugar), A2 (50% nipah sugar), A3 (60% nipah sugar) and repeated 3 times. The test parameters observed include Color (L *, a *, and b *), gelling point, water content, ash content, and mineral content (K, Mg, and Fe). The concentration of added nipah sugar significantly affected the color L* (Lightness), a* (Redness), b* (Yellowness), gelling point, water content, ash content, potassium (K), and iron (Fe) mineral content, but did not significantly affect the magnesium (Mg) mineral content in seaweed jam (Eucheuma cottonii). The characteristics of seaweed jam with the addition of nipah sugar produced are color L* (Lightness) 51.35 - 82.93, a* (Redness) -0.25 - 18.21, b* (Yellowness) 11.51 - 43.87, gelling point 42.87 - 51.43℃, water content 33.36 - 45.10%, ash content 0.673 - 1.635%, potassium mineral content 898.05 - 2682.05 ppm, magnesium 96.84 - 110.3 ppm, iron 3.71 - 10.95 ppm. Keywords : concentrations, Eucheuma cottonii, nipah sugar, physicochemical, seaweed jamPITO BERLIANO, Analisa karakteristik fisikokimia selai rumput laut (Eucheuma cottonii) dengan penambahan gula nipah (Nypa fruticans) (Dibimbing oleh INDAH WIDIASTUTI dan PUSPA AYU PITAYATI) Eucheuma cottonii dapat dijadikan bahan pembuatan selai karena mengandung karaginan yang dapat membentuk gel, pada umumnya pembuatan selai akan menggunakan gula pasir, gula pasir cenderung hanya mengandung sukrosa, berbeda dengan gula nipah yang memiliki kandungan yang lebih kompleks. Sehingga gula nipah dapat menjadi bahan tambahan dalam pembuatan selai rumput laut menggantikan gula pasir. Penelitian ini bertujuan untuk mengukur pengaruh penambahan gula nipah (Nypa fruticans) terhadap karakteristik fisikokimia selai rumput laut (Eucheuma cottonii) penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan perlakuan perbedaan konsentrasi gula nipah dengan 4 taraf perlakuan A0 (50% gula pasir), A1 (40% gula nipah), A2 (50% gula nipah), A3 (60% gula nipah) dan dilakukan pengulangan sebanyak 3 kali. Parameter pengujian yang diamati meliputi Warna (L*, a*, dan b*), gelling point, kadar air, kadar abu, dan kadar mineral (K, Mg, dan Fe). Konsentrasi penambahan gula nipah berpengaruh nyata terhadap warna L* (Lightness), a* (Redness), b* (Yellowness), gelling point, kadar air, kadar abu, kadar mineral potassium (K), dan iron (Fe), tetapi tidak berpengaruh nyata terhadap kadar mineral magnesium (Mg) pada selai rumput laut (Eucheuma cottonii). Karakteristik selai rumput laut dengan penambahan gula nipah adalah warna L* (Lightness) 51,35 - 82,93, a* (Redness) - 0,25 – 18,21, b* (Yellowness) 11,51 – 43,87, gelling point 42,87 – 51,43℃, kadar air 33,36 – 45,10%, kadar abu 0,673 – 1,635%, kadar mineral potassium 898,05 – 2682,05 ppm, magnesium 96,84 – 110,3 ppm, iron 3,71 – 10,95 ppm. Kata Kunci : Eucheuma cottonii, fisikokimia, gula nipah, konsentrasi, selai rumput laut.
