PENGGUNAAN SISTEM KOMUNIKASI ALTERNATIF I-TALK UNTUK MENINGKATKAN KETERAMPILAN KOMUNIKASI SISWA CEREBRAL PALCY

Faktor yang melatarbelakangi penelitian ini ialah terdapat siswa Cerebral Palsy yang mengalami kesulitan dalam melakukan proses komunikasi terutama dalam berbicara. Gangguan bicara yang dialami subjek disebabkan karena adanya kekakuan pada otot organ bicara. Otot pada organ bicara yang mengalami kekakuan atau lumpuh (spams) diantaranya adalah lidah, bibir dan rahang bawah dan menyebabkan artikulasi tidak benar. Hal ini menyebabkan pesan yang disampaikan secara verbal oleh anak sulit dimengerti komunikan, akibatnya apa yang ia butuhkan tidak dapat terpenuhi. Penelitian ini bertujuan untuk mengembangkan sistem Alternative and Augmentative Communication (AAC) dan mengetahui pengaruhnya terhadap keterampilan komunikasi subjek. Metode penelitian yang digunakan oleh peneliti ialah mix methode dengan pendekatan exploratory sekuensial. Metode ini dipilih karena peneliti harus mengolah data deskripsi yang menghasilkan penjelasan mengenai kondisi objektif subjek serta pengembangan sistem AAC dengan menggunakan metode kualitatif, serta data pengukuran keterampilan komunikasi subjek sebelum dan sesudah menggunakan AAC, dengan metode penelitian kuantitatif. Hasil dari penelitian ini ialah sebuah sistem komunikasi alternatif I-Talk. I-Talk memiliki dua komponen utama, yakni tombol pemanggil untuk memanggil orang disekitar ketika membutuhkan bantuan dan papan gambar untuk menyampaikan kebutuhan. Hasil lain dalam penelitian ini ialah berupa peningkatan keterampilan komunikasi subjek. Peningkatan keterampilan komunikasi terlihat dari keterampilan komunikasi subjek yang pada awalnya belum bisa dipahami sama sekali oleh komunikan, setelah menggunakan I-Talk meningkat dengan indikator mampu memanggil orang tua, pengasuh dan guru. Selain itu, mampu menanggapi pertanyaan komunikan, menyampaikan keinginan saat ingin minum air, teh gelas, susu, roti, mie, snack, buah, buang air besar, buang air kecil, jalan- jalan,nonton TV, pulang ke rumah dan mendengar musik.;---The factor that underlying this research is there are student of Cerebral Palsy who have difficulty in doing communication process especially in talking. Speech disorders experienced by the subject caused by the stiffness of the muscles talking organs. Muscles in the speech organs that have stiffness or paralysis (spasm) include the tongue, lips and lower jaw and cause the articulation is not true. This causes the message delivered verbally by the child is difficult to understand communicant, consequently what he needs can not be fulfilled. This research aims to develop Alternative and Augmentative Communication (AAC) system and to know its influence on subject communication skill. Research method used by researcher is mix method with sequential exploratory approach. This method was chosen because the researcher had to process the description data which resulted in the explanation of the objective condition of the subject and the development of AAC system using qualitative method, as well as the data of communication skills of the subject before and after using AAC, with quantitative research method. The result of this research is an alternative I-Talk communication system. I-Talk has two main components, namely a call button to call people around when needing help and a drawing board to convey a need. Another result in this research is the improvement of subject communication skills. Improved communication skill seen from subject communication skills that intially can not be understood at all by the communicant, after using I-Talk communication skills increased with indicators able to call parents, caregivers,and teacher. In addition, able to respond of question communicant, convey the desire when want to drink water, ‘teh gelas’, milk, bread, noodles, snack, fruits, toilet, walk, watch TV, go home and listen music

Properties of Bio composite Film Based on Whey Protein Isolate Filled with Nanocrystalline Cellulose from Pineapple Crown Leaf

Among the main bio-based polymer for food packaging materials, whey protein isolate (WPI) is one of the biopolymers that have excellent film-forming properties and are environmentally friendly. This study was performed to analyse the effect of various concentrations of bio-based nanocrystalline cellulose (NCC) extracted from pineapple crown leaf (PCL) on the properties of whey protein isolate (WPI) films using the solution casting technique. Six WPI films were fabricated with different loadings of NCC from 0 to 10 % w/v. The resulting films were characterised based on their mechanical, physical, chemical, and thermal properties. The results show that NCC loadings increased the thickness of the resulting films. The transparency of the films decreased at higher NCC loadings. The moisture content and moisture absorption of the films decreased with the presence of the NCC, being lower at higher NCC loadings. The water solubility of the films decreased from 92.2% for the pure WPI to 65.5% for the one containing 10 % w/v of NCC. The tensile strength of the films peaked at 7% NCC loading with the value of 5.1 MPa. Conversely, the trend of the elongation at break data was the opposite of the tensile strength. Moreover, the addition of NCC produced a slight effect of NCC in FTIR spectra of the WPI films using principal component analysis. NCC loading enhanced the thermal stability of the WPI films, as shown by an increase in the glass transition temperature at higher NCC loadings. Moreover, the morphology of the films turned rougher and more heterogeneous with small particle aggregates in the presence of the NCC. Overall, the addition of NCC enhanced the water barrier and mechanical properties of the WPI films by incorporating the PCL-based NCC as the filler

Optimization of Biocomposite Film Based on Whey Protein Isolate and Nanocrystalline Cellulose from Pineapple Crown Leaf Using Response Surface Methodology

This study employed response surface methodology to optimize the preparation of biocomposites based on whey protein isolate, glycerol, and nanocrystalline cellulose from pineapple crown leaf. The effects of different concentrations of nanocrystalline cellulose as a filler and glycerol as a plasticizer on the thickness, the tensile strength, and the elongation at break on the resulting biocomposite films were investigated. The central composite design was used to determine the optimum preparation conditions for biocomposite films with optimum properties. The regression of a second-order polynomial model resulted in an optimum composition consisting of 4% glycerol and 3.5% nanocrystalline cellulose concentrations, which showed a desirability of 92.7%. The prediction of the regression model was validated by characterizing the biocomposite film prepared based on the optimum composition, at which the thickness, tensile strength, and elongation at break of the biocomposite film were 0.13 mm, 7.16 MPa, and 39.10%, respectively. This optimum composition can be obtained in range concentrations of glycerol (4–8%) and nanocrystalline cellulose (3–7%). Scanning electron microscope images showed that nanocrystalline cellulose dispersed well in the pure whey protein isolate, and the films had a relatively smooth surface. In comparison, a rough and uneven surface results in more porous biocomposite films. Fourier transform infrared spectroscopy revealed that nanocrystalline cellulose and glycerol showed good compatibility with WPI film by forming hydrogen bonds. The addition of nanocrystalline cellulose as a filler also decreased the transparency, solubility, and water vapor permeability and increased the crystallinity index of the resulting biocomposite film

Isolation and characterization of nanocrystalline cellulose isolated from pineapple crown leaf fiber agricultural wastes using acid hydrolysis

Pineapple crown leaf fiber (PCLF) is one of the major biomass wastes from pineapple processing plants. It consists mostly of carbohydrate polymers, such as cellulose, hemicellulose, and lignin. It can be further processed to form a more valuable and widely used nanocrystalline cellulose (NCC). This study investigates the effect of hydrolysis time on the properties of the produced NCC. The acid hydrolysis was conducted using 1 M of sulfuric acid at hydrolysis times of 1–3 h. The resulting NCCs were then characterized by their morphology, functional groups, crystallinity, thermal stability, elemental composition, and production yield. The results show that the NCC products had a rod-like particle structure and possessed a strong cellulose crystalline structure typically found in agricultural fiber-based cellulose. The highest NCC yield was obtained at 79.37% for one hour of hydrolysis. This NCC also displayed a higher decomposition temperature of 176.9 C. The overall findings suggest that PCLF-derived NCC has attractive properties for a variety of applications
