Abstract

Kulit biji kakao merupakan hasil samping agroindustri yang belum dimanfaatkan secara optimal, padahal mengandung senyawa bioaktif penting seperti polifenol (katekin, epikatekin, antosianin, tannin), alkaloid (theobromine dan kafein), serat pangan, protein, serta mineral esensial yang berpotensi tinggi untuk dikembangkan sebagai bahan pangan fungsional. Melalui teknologi nano, kulit biji kakao dapat dimodifikasi menjadi nanopartikel sehingga memiliki sifat fisikokimia, fungsional, dan amilografi yang lebih sesuai dengan kebutuhan industri pangan. Penelitian ini bertujuan untuk mengevaluasi sifat fungsional, amilografi, dan fisikokimia nanopartikel kulit biji kakao terfermentasi dari kategori mutu edel, bulk, serta campuran keduanya. Penelitian dilakukan secara eksperimental dengan pendekatan deskriptif menggunakan tiga jenis sampel dan dua ulangan. Hasil penelitian menunjukkan bahwa perbedaan kategori mutu tidak memberikan pengaruh signifikan terhadap sifat fungsional, amilografi, dan fisikokimia. Namun, kategori mutu edel memiliki nilai kelarutan (41,27%), swelling volume (96 mL/g), dan daya serap air (3,05 g/g) tertinggi. Hal ini diduga terkait dengan kadar serat dan amilosa yang lebih tinggi serta kadar lemak yang lebih rendah. Secara umum, ketiga sampel menunjukkan profil viskositas rendah yang menandakan kemampuan pengembangan terbatas, namun memiliki kapasitas penyerapan air yang tinggi. Temuan ini mengindikasikan bahwa kulit biji kakao, khususnya kategori edel, berpotensi dikembangkan sebagai bahan pangan fungsional dalam bentuk nanopartikel yang aplikatif untuk industri.

Abstract

Rice husk as organic waste can be used as raw material for activated charcoal. The quality of activated charcoal is influence by the ash content in the raw material, which can inhibit the development of carbon pores and the concentration of chemical compounds during chemical activation. The purpose of this study was to determine the best treatment from pre-treatment using NaOH and KOH concentrations of 10, 20, and 30% on rice husk charcoal activation to produce activated charcoal with the best morphological and proximate characteristics. The method used in this study is an experimental laboratory approach for the characterization and activation of rice husk charcoal. The results showed that the lowest water content of activated charcoal was obtained with N30 treatment, namely non-pre-treatment with activation using 30% KOH and P30 treatment (pre-treatment and 30% KOH), namely 1.23 and 1. 47%. Activated charcoal with NaOH pre-treatment all had lower ash content compared to non-pre-treated activated charcoal and commercial charcoal. The morphological characteristics showed that the development of activated charcoal pores of rice husk with pre-treatment was better than non-pre-treatment, which was indicated by the number of pores in a certain area unit. Increasing the concentration of KOH resulted in a decrease in the water content and ash content as well as an increase in the porosity of the activated charcoal of rice husk.
