Abstract

Produksi bioetanol menggunakan hidrolisat ampas tebu dengan sistem selulase Bacillus subtilis memiliki keuntungan karena ampas tebu merupakan bahan baku yang melimpah dan murah, serta proses hidrolisis yang efisien dapat mengonversi lignoselulosa menjadi glukosa yang siap difermentasi. Penelitian ini bertujuan untuk mengevaluasi produksi bioetanol dari hidrolisat ampas tebu dengan menggunakan sistem selulase Bacillus subtilis dan variasi waktu fermentasi serta jenis inokulum. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan dua faktor: waktu fermentasi (24, 48, 72 jam) dan jenis inokulum (Saccharomyces cerevisiae 5% dan ragi tape 5%), masing-masing pengulangan triplo. Karakteristik bioetanol yang dihasilkan dianalisa rendemen, efisiensi fermentasi dan kadar alkohol. Analisis data dilakukan menggunakan uji ANOVA dua arah, dilanjutkan dengan uji Tukey (α=0,05%) untuk menentukan perlakuan terbaik. Hasil penelitian menunjukkan bahwa perlakuan dengan Saccharomyces cerevisiae 5% pada waktu fermentasi 48 jam memberikan hasil terbaik, dengan rendemen bioetanol 122,16 mL/kg dan kadar alkohol 76,8%. Implikasi dari hasil ini menunjukkan bahwa pemilihan inokulum dan waktu fermentasi yang tepat sangat penting untuk memaksimalkan produksi bioetanol dari ampas tebu

Abstract

Cocoa pulp is a layer of mucus covering the beans which mostly consists of water and a layer of nutritional components that are quite high, including sucrose, glucose, organic acids and fiber. The fermentation process is carried out to release the cocoa pulp to produce cocoa pulp extract. This research aims to determine the effect of fermentation period on the characteristics of cocoa pulp extract and syrup. The research design used was a randomized block design, with period fermentation treatment were 24-hour, 48-hour, 72-hour, 96-hour, and each treatment was repeated 4 times. The parameters observed in the cocoa pulp extract were antioxidant activity, pH, total acid, yield and organoleptic (color, aroma and taste), while the organoleptic properties of the syrup were only observed. The results showed that treatment of fermentation period had a significant effect on pH, total acid and yield, however, it did not have a significant effect on antioxidants. The fermentation period also has a significant effect on the color, flavor and taste of cocoa pulp extract and the of cocoa syrup.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh formulasi perbandingan tepung ubi ungu (Ipomoea batatas L.) dan tepung daun kelor (Moringa oleifera) terhadap karakteristik kimia (proksimat) dan kandungan antioksidan pada produk brownies sebagai pangan fungsional. Ubi ungu diketahui mengandung senyawa antosianin yang berperan sebagai antioksidan alami, sedangkan daun kelor mengandung protein nabati, vitamin, mineral, serta senyawa bioaktif seperti flavonoid yang bermanfaat dalam menjaga kesehatan tubuh.Penelitian ini menggunakan tiga formulasi proporsi tepung ubi ungu dan tepung kelor, yaitu 100%:0% (kontrol), 90%:10%, dan 80%:20%. Setiap perlakuan dianalisis menggunakan uji proksimat untuk menentukan kadar air, abu, lemak, protein, dan karbohidrat. Uji antioksidan dilakukan terhadap formula terbaik menggunakan metode DPPH dan dianalisis dengan spektrofotometer UV-Vis.Hasil penelitian menunjukkan bahwa peningkatan proporsi tepung kelor secara signifikan meningkatkan kadar protein dan abu, namun menurunkan kadar lemak dan karbohidrat. Kadar air juga mengalami peningkatan, namun masih berada dalam batas aman sesuai SNI. Formula terbaik adalah formulasi C (80% tepung ubi ungu : 20% tepung kelor), dengan kadar protein tertinggi sebesar 6,80% dan nilai IC50 sebesar 61,93 ppm, yang dikategorikan sebagai antioksidan kuat.Berdasarkan hasil tersebut, dapat disimpulkan bahwa substitusi sebagian tepung ubi ungu dengan tepung daun kelor dalam pembuatan brownies mampu meningkatkan nilai gizi dan aktivitas antioksidan produk. Brownies ini berpotensi sebagai alternatif camilan sehat dan merupakan contoh pangan fungsional berbasis bahan lokal yang mendukung upaya peningkatan kesehatan masyarakat.
