Noise exposure could have a negative effect on humans in the form of hearing loss, sleep disturbances, high blood pressure and heart problems, respiratory and metabolic disorders, mental health disorders and cognitive impairment. So noise control efforts are needed. Noise control efforts was carried out by making porous absorber of noise control panel by utilizing abundant natural resources in the form of coconut fiber, utilization of PET fiber from textile waste (shoody fiber) and low melt polyester. From the test results obtained that all combinations meet the criteria for sound absorption from class B to E, and the results of maximum absorption are 0.88 absorption coefficient obtained by a combination of three layers between 50% coconut fiber, 20% shoody fiber and 30% low melt polyester.

Serat nano kitosan telah berhasil dibuat dengan penambahan polietilen oksida (PEO) sebagai polimer sekunder pada kondisi larutan dan parameter proses pemintalan elektrik yang optimum. Pada penelitian ini, larutan polimer kitosan/PEO pada berbagai konsentrasi (3,2, 3,6, dan 4 wt%) dan rasio (3:2 dan 1:1) dipintal secara elektrik ( electrospinning ) untuk memperoleh serat dengan morfologi paling baik. Selain kondisi larutan, parameter proses pintal elektrik yang penting seperti tegangan, laju alir umpan, dan jarak antara jarum dengan kolektor juga disesuaikan untuk mendapatkan proses dengan kondisi jet polimer yang stabil. Serat nano yang terbaik yakni tanpa butiran polimer ( polymer microspheres ) dan minim jumlah manik-manik ( beads) berhasil diperoleh pada konsentrasi kitosan/PEO 4 wt% dan rasio 3:2. Parameter proses yang digunakan untuk mendapatkan serat ini yaitu tegangan 30 kV, laju alir umpan 0,3 ml/jam, dan jarak antara jarum dan kolektor 30 cm. Karakterisasi morfologi serat dari setiap eksperimen dilakukan dengan menggunakan mikroskop Phenom. Selanjutnya, serat nano terbaik yang diperoleh dikarakterisasi dengan menggunakan SEM dan diameter rata-rata serat diukur dengan aplikasi ImageJ. Hasil menunjukkan bahwa serat nano yang dihasilkan pada kondisi optimum memiliki diameter rata-rata 68 nm dan distribusi ukuran diameter serat tersebar cukup lebar mulai dari 30-150 nm.

Exploration of banana peduncle waste is an attempt to search new product material alternatives. The purpose of this research is to reveal the character of banana peduncle fiber especially in its ability to absorb the color compared to abaca fiber and coir fiber. The color intensity test was conducted by calculating the luminance or the intensity of light which was reflected back by the surface area of the fiber. The result of this research was the bleached banana peduncle fiber generates more vivid and brighter color than the unbleached banana peduncle fiber. The unbleached one was similar to abaca fiber especially in absorbing red color (ratio = 1.00) and blue color (ratio = 1.01), however, it was lower than abaca fiber in absorbing green color (ratio = 0.98) and yellow color (ratio = 0.92). Thus, the unbleached banana peduncle fiber can be used effectively to perform color gradation of red and blue. Comparing to coir fiber, the absorption of banana peduncle fiber toward red, green, blue, and yellow color was higher. This research can be applied in coloring process of product material because it can accelerate production process and save production cost.

One of the processes to improve the function of cotton fabric is microcapsule finishing. Microcapsules are expected to have adequate resistance to surface of cotton fabric. However, since microcapsule shell has no chemical bond with cotton fabric, a binder is used for example polyacrylic and polyurethane . The aim of this research is to study the effectiveness of polyacrylic and polyurethane binder in cotton fabric microcapsule finishing using pad ding technique . The cotton fabric is immersed in a solution of microcapsules and binder for (5-10) minutes at room temperature, press with 90% Wet Pick Up (WPU), dried at 100 ° C for 60 seconds then followed by a temperature of 110 ° C for 120 seconds. The cotton finishing fabric of microcapsule observed from its surface with Scanning Electron Micros c ope (SEM), tested its washing fastness with Launder-O-meter, its tensile strength with tensile tester, and its stiffeness with stiffeness tester. Particle size of microcapsules analyzed with Particle Size Analyzer (PSA), and shell of microcapsule with Fourier Transform Infra R ed (FTIR). Results showed that the microcapsule size of 1.14 μm with melamine formaldehyde shell, the use of polyacrylate and polyurethane binder could maintain the microcapsules in the fabric up to ten times, increase the tensile strength and stiffness of cotton fabric.

Cotton is widely used for clothing material, because it is able to absorb sweat/water, so comfortable to wear. But the product is still an export comodity and waste that occurs after spinning into yarn is about (4 - 5)%. Much of the waste still contains short fibers, potentially as composite reinforcement; and the rest are dirt, dust, soil and others. Therefore, in the framework of handling and utilization of such waste, in order to produce an added value product, then a research was conducted to make biocomposites using that waste. The purpose is to get a biocomposite with a cotton fiber waste of felt (a nonwoven product) with a low melt polyester matrix and manufactured wood in the form of a fiber board with an epoxy resin matrix that can meet applicable standards. From the test results, it is known that the felt can absorb sound up to 78% at the reference frequency of 5000 Hz (meets minimum standards for sound absorbing coefficient, based on ISO 11654: 1997), so it can be used as a sound absorber material (for building/automotive) and can also be used as raw material for automotive textile (door trim, dashboard or head lining). In addition, the fiber board also has performance that meets the standard (SNI 01-4449-2006) and can reflect sound ≥ 90%, so it can be used as a sound reflector interior panel
