Abstract

Isolasi selulosa dari tanaman Eceng Gondok (Eichornia crassipes) berhasil dilakukan dengan menggunakan metode bleaching diikuti dengan alkalinasi. Metode bleaching dilakukan menggunakan NaOCl dengan pengadukan dan pemanasan suhu rendah yaitu 80 oC selama 4 jam, diikuti dengan metode alkalinasi menggunakan NaOH dengan pemanasan pada suhu rendah yaitu 45 oC selama 3 jam. Penerapan metode bleaching dan alkalinasi ini bertujuan untuk delignifikasi dengan memutuskan rantai polimerik diantara selulosa dengan lignin atau hemiselulosa. Selain itu, proses oksidasi lanjut juga terjadi karena keberadaan HOCl dan OH- sebagai hasil peruraian NaOCl dan NaOH. Setelah pencucian hingga pH netral, hasil isolasi yang didapatkan adalah berupa serbuk putih yang secara fisis berbeda dari material awal sebelum perlakuan. Hasil rendemen berkisar 6 ? 20% dengan penyusutan massa sebesar 80%. Analisa gugus fungsi hasil isolat dengan spektrometer Fourier Transform Infrared (FTIR) menunjukkan keberadaan serapan dari gugus hidroksil ?OH, ?C?H, =C?H, ?OH dan C=O (gugus karboksilat), C-H dan C?O, dan C?O?C pada cincin piranosa yang menguatkan keberhasilan isolasi selulosa. Berdasarkan observasi morfologi dan struktur dengan menggunakan scanning electron microscope (SEM), selulosa hasil isolasi berbentuk butiran kristal dengan ukuran mikrometer yang secara signifikan berbeda dari penampakan fisis serat awal sebelum perlakuan.Isolation of Cellulose Microfiber from Water Hyacinth (Eichornia crassipes) Waste by Bleaching-Alkalization Method. Cellulose isolation from water hyacinth plants (Eichornia crassipes) was successfully performed using bleaching followed by alkalization methods. The bleaching method was carried out using NaOCl with stirring dan heating at a low temperature of 80 oC for 4 hours. This method was then followed by an alkalization method using NaOH with heating at a low temperature of 45 oC for 3 hours. The application of the bleaching followed by alkalization method aimed to proceed the delignification by breaking the polymeric chain between cellulose dan lignin or hemicellulose. In addition, the process of advanced oxidation also occurred due to the presence of HOCl dan OH- decomposed from NaOCl dan NaOH. The solid was then washed until the pH of the solution was neutral. As results, the white powder solid was obtained which was physically different from the initial material before treatment. The yield obtained was around 6 ? 20% with a mass shrinkage of 80%. Analysis of the functional groups of the isolates using Fourier Transform Infrared (FTIR) spectrometers showed the presence of the hydroxyl groups ?OH, ?C?H, =C?H, ?OH dan C=O (carboxylic groups), CH dan C ?O, dan C?O?C on the pyranose ring that reinforces the success of the cellulose isolation. Based on morphological dan structural observations under a scanning electron microscope (SEM), the cellulose isolated was in crystalline granules in micrometer size which was significantly different compared to the physical appearance of the initial fiber before treatment.

Abstract

The chemical characteristics of composite material of iron oxide with carbon synthesized by arc discharge method in liquid medium have been identified. The liquid medium used in the method was ethanol with ammonia addition. The chemical characteristics of the resulting product were studied by Fourier transform infrared spectroscopy (FTIR) and energy dispersive X-ray (EDX). The morphology of the material was studied by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The observed materials have a spherical and orderly structure. The FTIR spectra profile shows the peaks of N-H and C-N. The amino groups coming from ammonia as a liquid medium during arc discharge were supposed to have been covalently attached to carbon materials composited with iron oxide. The elemental analysis of EDX confirms the presence of nitrogen elements that were not found on the materials synthesized in arc discharge without ammonia addition.

Abstract

Clustering is an unsupervised method to group multiple objects based on the similarity automatically. The quality of clustering accuracy is determined by the number of similar objects in a correct cluster group. The robust preprocessing process and the choice of cluster algorithm can increase the efficiency of clustering. The objective of this study is to observe the most suitable method to cluster document in Bahasa Indonesia. We performed tests on several cluster algorithms such as K-Means, K-Means++ and Agglomerative with various preprocessing stages and collected the accuracy of each algorithm. Clustering experiments were conducted on a corpus containing 100 documents in Bahasa Indonesia with a commonly used preprocessing scenario. Additionally, we also attach our preprocessing stages such as LSA function, TF-IDF function, and LSA / TF-IDF function. We tested various LSA dimension reductions values from 10% to 90%, and the result shows that the best percentage of reduction rates between 50%-80%. The result also indicates that K-Means++ algorithm produces better purity values than other algorithms.
