摘要:Pemanfaatan kolang-kaling sebagai produk pangan dalam bentuk serbuk memberikan nilai tambah bagi buah tersebut. Buah ini memiliki kandungan mineral yang cukup banyak, seperti: potassium, besi dan kalsium yang bermanfaat dan dapat memperlancar proses metabolisme dalam tubuh. Tujuan dari penelitian ini adalah untuk melihat pengaruh dari penambahan konsentrasi tepung agar pada pembuatan serbuk agar dari kolang-kaling. Penelitian dilakukan dengan penambahan tepung agar 1%, 2%, 3% dan 4% pada bubur kolang kaling. Hasil penelitian menunjukkan bahwa penambahan tepung agar secara statistik tidak berbeda nyata terhadap kadar air, kadar abu, kadar serat kasar, kadar karbohidrat dan jenis ikatan rangkap (uji FTIR), tetapi berbeda nyata pada tingkat kepercayaan 95% pada kadar beberapa mineral alami yaitu fosfor, kalsium dan besi. Perlakuan optimal didapatkan pada perlakuan penambahan tepung agar 2% dengan nilai kadar air 4,98%, kadar abu 0,49%, kadar serat 5,19%, kadar karbohidrat 64,29% dan mineral fosfor 400 ppm, kalsium 292,8 ppm dan besi 44,8 ppm, serta absorpsi air 10 kali. Produk memenuhi SNI 01-2802-1995 tepung agar-agar untuk kadar air, abu dan absorpsi air. ABSTRACT The utilization of kolang-kaling fruit as a food product in powder form can add the value of the fruit. The fruit has a lot of mineral content, such as: potassium, iron, and calcium which are useful and can facilitate the body metabolic processes. The research purpose was to find the addition effect of the concentration of agar flour in the making of kolang-kaling agar powder. The research was done with the addition of agar flour 1%, 2%, 3% and 4% into kolang-kaling puree. The results showed that the addition of agar flour statistically had no significant different to the water content, ash content, crude fiber content, carbohydrate content and type of double bond (FTIR test), but significantly different at 95% confidence on some natural minerals namely phosphorus, calcium and iron. The optimal treatment was obtained in the addition of 2% agar flour with a moisture content 4.98%, ash content 0.49%, fiber content 5.19%, carbohydrate content 64.29% and minerals phosphorus 400 ppm, calcium 292.8 ppm and iron 44.8 ppm with 10 times water absorption. Products meet the SNI 01-2802-1995 agar-agar powder for moisture content, ash content, and water absorption.
