The area of critical land in Indonesia is increasing. Critical land rehabilitation has been carried out by one of the methods used is direct planting. However, direct planting has drawbacks, namely the seeds are very prone to be eaten by insects and birds, and the seeds are easily damaged due to environmental factors. One method that can be tested is the application of seedballs using adaptive plants, such as jackfruit (Artocarpus heterophyllus), bisbul (Diospyros blancoi), and merbau (Intsia bijuga). The purpose of this study was to formulate seedballs and their application for the growth of jackfruit (A. heterophyllus), bisbul (D. blancoi), and merbau (I. bijuga) plants. This study used a quantitative descriptive analysis method with 3 types of seedballs’ formulas. The results showed the fastest germination rate was produced by formula 1 (clay) on bisbul, formula 2 (clay: topsoil) on jackfruit, and formula 3 (clay: topsoil: husk charcoal: palm waste) on merbau. The highest seed germination capacities were formulas 1 and 3 for jackfruit species, formulas 2 and 3 for bisbul species, as well as formulas 1 and 2 for merbau species. Formula 3 is generally able to increase the height, diameter, and number of leaves of plants. Keywords: acceleration of rehabilitation, adaptive plant, oil palm waste

Review: Potensi Tandan Kosong Kelapa Sawit sebagai Bahan Baku Pembuatan Bioetanol dengan Metode Fed Batch pada Proses Hidrolisis

et al. 2021

Peningkatan kebutuhan energi terutama bahan bakar minyak yang tidak diimbangi dengan ketersediaan sumber energi tak terbarukan akan mengakibatkan kelangkaan energi. Pembuatan bahan bakar terbarukan merupakan solusi untuk mengatasi kelangkaan tersebut, salah satunya bioetanol. Biomassa Tandan Kosong Kelapa Sawit (TKKS) merupakan bahan baku yang cocok untuk pembuatan bioetanol karena jumlahnya yang melimpah dan mengandung lignoselulosa. Bioetanol dapat diperoleh melalui proses fermentasi dengan metode yang digunakan adalah Fed Batch Simultaneous Saccharification Fermentation. Pretreatment berupa size reduction dan delignifikasi direkomendasikan sebelum proses hidrolisis enzimatik dan fermentasi secara serentak. Metode pengumpanan Fed Batch pada High Total Solid Loading (HTSL) direkomendasikan sebagai strategi pengumpanan pada proses hidrolisis enzimatik dengan jumlah frekuensi yang tinggi memberikan hasil kadar etanol lebih tinggi.The enhancement of energy needs, especially fuel, that is not complemented by the availability of non-renewable energy sources, would affect the deficient of energy. The production of renewable fuel such as bioethanol is a solution to overcome that deficiency. One of the substrates that are appropriate to be processed into bioethanol is Oil Palm Empty Fruit Bunch (OPEFB) because of abundant and lignocellulosic biomass. Bioethanol can be produced through the fermentation process by Fed-Batch Simultaneous Saccharification Fermentation method. Size reduction and delignification for pretreatment are recommended before the simultaneous enzymatic hydrolysis process and fermentation. Using the fed-batch as a feeding method of High Total Solid Loading (HTSL) is recommended for feeding strategy in hydrolysis enzymatic process with high frequency that can produce a higher yield of ethanol.

“…Setiap pengolahan satu ton tandan buah segar (TBS) akan menghasilkan TKKS sebanyak 22-23% atau sebanyak 220-230 kg. Limbah ini belum dimanfaatkan secara optimal oleh sebagian besar pabrik kelapa sawit (PKS) dan masyarakat (Salmina, 2016). Sebagian besar PKS masih membakar TKKS dalam incinerator, padahal cara ini sudah dilarang oleh pemerintah.…”

Oil Palm Empty Fruit Bunches (OPEFB) are the largest cellulose waste produced by oil palm plantations. Each processing of one ton of Fresh Fruit Bunch (FFB) will produce OPEFB as much as 22-23% or 220-230 kg. OPEFB waste has not been utilized optimally by most palm oil mills and communities. It was reported that OPEFB contains 32.57% cellulose, 27.70% hemicellulose, and 26.49% lignin. The purity of cellulose component in OPEFB can be increased by delignification and hydrolysis of OPEFB. This research aims to produce alpha-cellulose from OPEFB with the highest purity level. The stages of the process include biologically delignification using white oyster mushroom (Pleurotus ostreatus), chemical delignification using 17,5% NaOH solution, and combination of treatment using solution of 17,5% NaOH and hydrolysis using 10% H2SO4solution. The analysis was carried out using the Fourier Transform Infrared Spectroscopy (FTIR). The best result of alpha-cellulose purity was by the treatment of delignified NaOH baglog resulting in 97.43% alpha-cellulose content, 4.47% pentosan hemicellulose level, and undetectable lignin levels.The results of FT-IR spectrum from alpha-cellulose obtained from OPEFB has shown functional groups contained in alpha-cellulose polymers including O-H groups at wave number 3289 cm-1, C-H groups at wave number 2901 cm-1, and functional groups C-O at wave number 1372 cm-1.[Key words: hydrolysis, FT-IR, mushroom, bleaching, waste] Abstrak Tandan kosong kelapa sawit (TKKS) adalah limbah terbesar yang dihasilkan oleh perkebunan kelapa sawit.
