Abstract

Porang (konjac) plants have long been used as a food source and traditional medicine. Glucomannan derived from porang has been utilised for various uses such as antidiabetic and antihypercholesterolemia agent. This paper studies the mixture of porang flour and nano activated-carbon and its effect on the cholesterol activity of rats. The mixture of porang and activated carbon were subjected to test for male Sprague Dawley rats to test the antihypercholesterolemia activity. The result showed that concerted anticholesterol activity of porang and nano activated-carbon revealed the cholesterol level decreases in rat's blood. However, the different treatments of unleached and leached porang either leached porang and nano activated-carbon applied in the experiments showed that the levels of cholesterol decrease were slightly different (16–18%). Low glucomannan content as the alleged anticholesterol agent was regarded quite effective in lowering the cholesterol level in rat's blood and comparable with those of simvastatin which achieved 18% reduction. Therefore, it indicates potential utilisation as a functional food for a cholesterol-lowering agent. The involvement of activated carbon in the alleged anticholesterol agent (leached porang flour) did little in enhancing the cholesterol level decrease in rat's blood. The glucomannan in both leached porang flour and leached porang flour + nano activated-carbon shows potential utilisation as an anticholesterol agent. Yet, raw (unleached) porang is prospectively potential as a functional food for cholesterol-lowering.

Abstract

Biopelet adalah bahan bakar alternatif terbarukan yang dibuat dari biomassa pertanian. Jerami padi merupakan biomassa pertanian yang berpotensi dimanfaatkan sebagai bahan baku biopelet, namun memiliki nilai kalor yang relatif rendah. Oleh karena itu, diperlukan kombinasi dengan biomassa lain yang memiliki nilai kalor yang lebih tinggi, seperti serbuk gergaji kayu sengon, untuk meningkatkan kualitas dan energi biopelet yang dihasilkan. Tujuan penelitian ini adalah untuk memperoleh formulasi bahan baku biomassa untuk menghasilkan biopelet yang baik dari campuran jerami padi dan serbuk gergaji kayu sengon. Metode yang digunakan pada penelitian adalah metode pengempaan pada suhu 200 oC dengan ukuran sampel 40 mesh. Penelitian ini menggunakan Rancangan Acak Lengkap Faktorial dengan dua faktor yaitu komposisi (% bobot) campuran bahan baku jerami:serbuk gergaji kayu sengon, yaitu jerami padi saja (A), 25:75 (AB1), 50:50 (AB2), 75:25 (AB3), dan serbuk gergaji kayu sengon saja (B). Faktor kedua adalah variasi waktu pengempaan (10, 15, dan 20 menit). Kualitas biopelet akan diuji sesuai persyaratan SNI 8675:2018. Penelitian memperlihatkan bahwa biopelet terbaik dihasilkan oleh campuran jerami:serbuk gergaji kayu sengon 25:75 (AB1) dengan waktu pengempaan 20 menit. Biopelet yang dihasilkan memiliki karakteristik densitas 1.00 g/cm3, kadar air 0.09%, kadar abu 5.5%, nilai kalor 23.3 MJ/kg, dengan laju konsumsi pembakaran biopelet 0.52 g/detik.
