Abstract
Peningkatan produksi dan nilai ekonomi minyak sawit melalui konversi menjadi produk yang bernilai ekonomi lebih tinggi akan memberikan dampak yang berarti terhadap pendapatan Indonesia. Di samping itu, kelapa sawit juga merupakan salah satu sumber penghasil limbah pertanian. Dalam satu ton kelapa sawit, terdapat 230-250 kg tandan kosong kelapa sawit, 130-150 kg serat, 65 kg cangkang dan 55-60 kg biji dan 160-200 kg minyak mentah. Salah satu pemanfaatan tandan kosong kelapa sawit (TKKS) menjadi bioetanol generasi-2 telah dilakukan di PP-Kimia LIPI. Produksi bioetanol generasi-2 dari tandan kosong kelapa sawit (TKKS) yang ada di PP-Kimia LIPI juga menghasilkan beberapa limbah, antara lain limbah pretreatment dan limbah destilasi. Limbah destilasi ini masih memiliki kandungan glukosa, xylosa, dan etanol sehingga memiliki potensi untuk di proses kembali guna mendapatkan produk baru yang lebih bernilai. Pengolahan limbah destilasi ini dapat dilakukan salah satunya dengan cara proses hidrotermal yang merupakan suatu proses ideal yang cocok untuk bahan baku basah seperti lumpur atau slurry. Penelitian ini menggunakan beberapa analisa, yaitu analisa HPLC dan analisa elemen CHON sebelum proses hidrotermal serta analisa GC-MS sesudah proses hidrotermal. Data yang diperoleh dari hasil analisis GC-MS berupa data kandungan senyawa kimia meliputi data angka dan grafik. Dari data angka tersebut kemudian diolah untuk mengetahui presentase mol tiap-tiap senyawa kimia berdasarkan produksi liquid. Dari perhitungan tersebut maka dapat diketahui kondisi optimum untuk mendapatkan kandungan senyawa kimia terbaik. Hasil yang diperoleh bahwa pada hasil proses hidrotermal, diketahui limbah destilasi bioetanol generasi-2 masih memiliki kandungan asam asetat, fenol, dan 2-pyrollidinone. Untuk mendapatkan hasil asam asetat tertinggi dapat digunakan temperatur 250°C. Untuk mendapatkan hasil fenol tertinggi dapat digunakan temperatur 300°C. Dan untuk mendapatkan hasil 2-pyrrolidinone tertinggi dapat digunakan temperatur 325°C. Dari kandugan yang telah diketahui, dapat disimpulkan bahwa hasil proses destilasi limbah destilasi hidrotermal hanya dapat dijadikan bahan sediaan kimia atau chemical feedstock.

ix AMI MAHARANI PUTRI. 115100207111011. Product Identification of Hydrothermal Liquefaction Process Distillation Waste of 2nd Generation Bioetanol. TA. Pembimbing: Dr. Ir. Bambang Susilo, M.Sc., Agr.; Dr. Ir. Bambang Dwi Argo, DEA; Sabar Pangihutan Simanungkalit, MT SUMMARY Increased production and economic value through the conversion of palm oil into products of high economic value more will give a significant impact on revenues in Indonesia. In addition, palm oil is also one source of agricultural waste. In one ton of palm oil, there are 230-250 kg of oil palm empty fruit bunches, fibers 130-150 kg, 65 kg and 55-60 kg of seed shells and 160-200 kg of crude oil. One of the utilization of oil palm empty fruit bunches (EFB) into second-generation bioethanol has been done in PP- Chemistry LIPI. 2nd generation bioethanol production from oil palm empty fruit bunches (EFB) in PP-Chemistry LIPI also produce some waste, including waste pretreatment and distillation waste. This distillation waste still contains glucose, xylose, and ethanol so that it has the potential for re-use in the process of getting new products more valuable. This distillation waste treatment can be done either by way of a hydrothermal process that is a process that is ideal suited for wet raw materials such as mud or slurry. This study uses several analysis, namely analysis and analytical HPLC CHON elements before the hydrothermal process and GC-MS analysis after hydrothermal process. Data were obtained from the GC-MS analysis of the data in the form of chemical compounds such as data points and graphs. From the numeric data is then processed to determine the mole percentage of each chemical compound based liquid production. From these calculations it can be seen optimum condition to obtain the best chemical compounds. The results obtained that the results of the hydrothermal process, known distillation waste generation bioethanol-2 still x contains acetic acid, phenol, and 2-pyrollidinone. To get the highest acetic acid can be used a temperature of 250 ° C. To get the highest phenol can be used a temperature of 300 ° C. And to get the highest 2-pyrrolidinone can use temperature of 325 ° C. From kandugan known, it can be concluded that the results of the process of distillation waste hydrothermal distillation can only be used as a chemical preparation or chemical feedstock
