Pcnclitian pcngembangan metode sintesis furfural dengan bahan dasar campuran limbah pertanian dilakukan dengan tujuan untuk menentukan waktu pemanasan dan konsentrasi asam optimum serta mewujudkan prinsip green chemistry. Dalam penelitian-inidigunakan campuran limbah pertanian ampas tebu, limbah daun nanas dan limbah tanaman jagung dengan perbandingan 1:1:I. Proses sintesis melalui tahap hidrolisis pentosan, dehidrasi, dan siklodehidrasi untuk membentuk furfural dengan menggunakan alat refluks termoditkasi. Identifikasi furfural menggunakan uji wama dengan anilin asetat, uji indeks bias, spektrofotometer UV -Vis, dan JR, serta Gc. Analisis pemenuhan prinsip green chemistl) mcnggunakan daftar ceck 12 prinsip green chemstry. Hasil penelitian menunjukkan bahwa: Waktu pcmanasan dan konsentrasi asam sulfat optimum pada pembuatan furfural dari campuran limbah pcrtanian adalah 5 jam dan konsentrasi asam sulfat 10% (1,876 M) dengan rendemen sebesar 5,58%. Mctode sintcsis furfural yang dikembangkan dapat memenuhi 11 dari 12 prinsip green chemistry yang telah ditetapkan. The study of developing furfural synthesis method from compost heap mixture had been done to determine optimum condition jar this process and to reach out the green chemistry principles. In this research. the compost heap mixture isfrom three kinds of compost heap (bagasse, pineapple leaf, waste of' corn plant) with same amount (I: 1:1). The steps offurjilral production process are hydrolysis of pentose by sulfuric acid. dehydration, and cyclode hydration to form furfural. It was produced by using a modtlication rellux apparatus. IdentifY offurfural product by using qualitative analysis color test with aniline acetate, refractive index test, UV-Vis, IR spectrophotometer, and Gc. Green chemistry principles are analyzed by using check list of 12principles of green chemistry. Based on this research was ohtained that the optimum concentration of sulluric acid is 10% (I.876M) with 5 hours heating process and 5,58% yield. Furfural synthesis methods had been developed in this study and reach out only 11 of the 12 principles of green chemistry set.
