Abstract

Currently, paper demand in the world has reached 394 million tons/year, while in Indonesia paper consumption has reached ± 8.9 million tons/year. As demand for pulp increases, paper production in Indonesia also needs to be increased. Paper products are produced from fibrous raw materials such as wood. The reduced availability of wood means that demand for wood raw materials cannot be met. This encourages the pulp and paper industry to look for sources of fiber. One natural resource that is easy to manage as a substitute raw material for the pulp and paper industry is water hyacinth. In this research, the delignification process of paper from water hyacinth was carried out using sodium hydroxide to determine the effect of NaOH on the manufacture of packaging paper with fixed variables, namely cooking temperature 100C, water hyacinth 60 gr, chlorine and starch 2gr each, and the variable changing the concentration of NaOH 2%, 2,5%, 3% with a cooking time of 90 minutes, 100 minutes and 110 minutes to obtain a paper tensile strength of 4,683 kN/m2, paper weight (gramatur) of 70 gr/m2 with a paper thickness of 0,7 mm. Abstrak Saat ini kebutuhan kertas didunia mencapai 394 juta ton/tahun sedangkan di Indonesia konsumsi kertas mencapai ± 8,9 juta ton/tahun. Bertambahnya kebutuhan pulp maka produksi kertas di Indonesia juga perlu dilanjutkan. Produk pulp dihasilkan dari bahan baku yang berserat seperti kayu. Berkurangnya ketersediaan kayu mengakibatkan permintaan bahan baku kayu tidak bisa dipenuhi. Hal ini mendorong indutri pulp dan kertas mencari sumber serat. Salah satu sumber daya alam yang mudah dikelolah sebagai bahan baku subtitusi industri pulp dan kertas adalah eceng gondok. Pada penelitian ini dilakukan proses delignifikasi kertas dari eceng gondok menggunakan katalis Natrium Hidroksida untuk mengetahui pengaruh NaOH terhadap pembuatan kertas kemasan dengan variabel tetap suhu pemasakan 100, eceng gondok 60 gr, kaporit dan tepung kanji masing-masing 2 gr dan variabel berubah konsentrasi NaOH 2%, 2,5%, 3% dengan lama waku pemasakan 90 menit, 100 menit dan 110 menit sehingga diperoleh kuat tarik kertas 4,683 kN/m2, berat kertas (gramatur) 70 gr/m2 dengan ketebalan kertas (Thickness) 0,7 mm.

Abstract

Furfural can be applied in various industrial fields as a solvent in the petroleum processing industry, lubricant manufacturing materials, nylon, shoe dyes, insecticide raw materials, herbicides, and fungicides. The method used in Furfural uses the supra yield process method, which can save energy, have high product purity, and do not produce by-products. The process of making fulfural with the supra yield method is bagasse from the separator basin is transported to the hydrolysis reactor to be homogenized with a 98% H2SO4 catalyst in a ratio (6: 1). Next is the hydrolysis and dehydrolysis process, where the hydrolysis process takes place in a reactor with a temperature of 700C and a pressure of 1 atm with a time of 1 hour using a semi-batch process heated using steam. The hydrolysis reaction results in pentose, which flows to the rotary vacuum filter to separate the cake and the filtrate. Then, in the dehydrolysis process, the pentose results from the previous process will be converted into Furfural using an H2SO4 catalyst and water, with a temperature of 2000C and a pressure of 15 atm for 75 minutes. Furthermore, the temperature will be lowered to 1000C. The final process is the separation and purification of the product; the mixer will add Toluene, and then it will flow to the distillation tower to separate Toluene and Furfural to get pure Furfural. As a top product, Toluene will evaporate at a temperature of 1150C. The final product with a purity of 99.9%. The primary tool used is a dehydration reactor that dehydrates pentose into Furfural. Abstrak Furfural dapat diaplikasikan pada berbagai bidang industri sebagai pelarut dalam industri pengolahan minyak bumi, bahan pembuatan pelumas, nilon, pewarna sepatu, bahan baku insektisida, herbisida dan fungisida. Adapun metode yang digunakan dalam fulfural yaitu menggunakan metode supra yield process, dimana pada metode ini dapat menghemat energi, kemurnian produk yang tinggi dan tidak menghasilkan produk samping. Proses pembuatan fulfural dengan metode supra yield yaitu ampas tebu dari bak separator diangkut menuju reaktor hidrolisis untuk dihomogenkan dengan katalis H2SO4 98% dengan perbandingan (6:1). Selanjutnya yaitu proses hidrolisa dan dehidrolisa, dimana proses hidrolisa berlangsung dalam reaktor dengan suhu 700C dan tekanan 1 atm dengan waktu 1 jam dengan menggunakan proses semi batch yang dipanaskan menggunakan steam. Hasil dari reaksi hidrolisa adalah pentosa yang selanjutnya dialirkan menuju rotary vacum filter untuk dipisahkan antara cake dan filtratnya.

Abstract

Using bioplastics as a substitute for plastics that decompose more slowly is one way to overcome the problem of plastic waste. Natural polymers are the basic ingredients of biodegradable plastics, or bioplastics. Water and microorganisms are two tools that can be used by the environment to break down bioplastics. The main qualitative research methods in this research are observation of test phenomena, biodegradation assessment, and water absorption capacity assessment. Biodegradation tests measure the rate at which microorganisms or the environment degrades biodegradable polymers. To find out how effectively plastic decomposes, samples of biodegradable plastic are planted in the soil. Based on samples with glycerol sorbitol content of 15%, 20% and 25%. The 15% concentration group experienced damage or weight loss more quickly compared to samples containing 20%, 25% and 15% glycerol. One thing that is taken into account in evaluating the quality of bioplastics is their ability to absorb water. Because it is related to how long plastic can last in storage, the greater the water absorption capacity of a bioplastic, the worse its quality. From the analysis of biodegradation and water absorption tests, the lower the concentration of glycerol and sorbitol, the more fragile the plastic produced, less elastic, and more easily decomposed by water, soil and other microorganisms. The higher the concentration of glycerol and sorbitol, the higher the results obtained. The plastic produced will be harder so that it is not easily decomposed or damaged.
