Abstract

Abstrak- Sebagai daerah sentra pengembangan perkebunan kelapa sawit dan industri crude palm oil (CPO), Kalimantan Timur memiliki potensi untuk menghasilkan tandan kosong kelapa sawit (TKKS) dalam jumlah yang cukup besar. TKKS merupakan limbah padat dari hasil industri CPO yang menggunakan tandan buah sawit (TBS) sebagai bahan bakunya.  Bagian TKKS adalah 23% dari TBS. TKKS memiliki nilai ekonomi yang tinggi jika diolah lebih lanjut. Salah satu cara yang digunakan adalah dengan menghidrolisis kandungan pentosan di dalam TKKS menjadi furfural. Tujuan penelitian ini adalah megembangkan teknik hidrolisis satu tahap TKKS menjadi furfural dengan bantuan gelombang mikro untuk mendapatkan waktu optimum yang dapat mengasilkan furfural maksimum.. Pada penelitian ini 10 gram TKKS ditambahkan dengan 250 mL H2SO4 15% sebagai katalis. Campuran kemudian dihidrolisis menggunakan bantuan gelombang mikro dengan variasi waktu 15, 30, 45, 60, 75, 90, dan 105 menit. Hasil analisa dengan Gas Chromatography (GC) menunjukkan hasil furfural tertinggi diperoleh pada waktu 75 menit dengan konsentrasi 1,34 mg/mL.  Kata Kunci: furfural, gelombang mikro, hidrolisis, TKKS Abstract- As a regional center for the development of oil palm plantations and crude palm oil (CPO) industry, East Kalimantan has the potential to produce oil palm empty fruit bunches (EFB) in large enough quantities. EFB is the solid waste from the palm oil industry which uses palm fruit bunches (FFB) as a raw material. EFB part is 23% of FFB. Whereas EFB has a high economic value if processed further. One of the method that is used to hydrolyze the content of pentosan in EFB into furfural. The purpose of this research is to develop one step hydrolysis technique of EFB into furfural  with microwaves assistance  to obtain the optimum time which can produce maximum furfural. In this research 10 grams of EFB was added with 250 mL of H2SO4 15%  as the catalyst. The mixture was then hydrolyzed using microwave-assisted with a time variety of for 15, 30, 45, 60, 75, 90, and105 minutes. The results of analysis by Gas Chromatography (GC) showed that the highest results of furfural  was at 75 minutes with a concentration of 1.34 mg / mL. Keywords: EFB, furfural, microwaves, hydrolysis

Abstract

Rice production in East Kalimantan is quite high. In the process of milling usually rice husk obtained is about 20-30% from grains weight produced. The quite potential amount of rice husk  has not yet widely utilized, even though rice husk contains pentosan which can be processed into furfural by hydrolysis method.  The purpose of this research is to develop one step hydrolysis technique of rice husk into furfural  with  microwaves assistance to obtain the optimum time which can produce maximum furfural. In  this research 50 grams of rice husk was added with 500 mL of H2SO4 1% as the catalyst. The mixture was then hydrolyzed using microwave-assisted method with a time variety of 15, 30, 45, 60, 75, 90, 105 and 120  minutes.  The result of analysis by Gas Chromatography (GC) showed that the highest result of furfural was at 90 minutes with a yield of 2.923%.
