Peningkatan penggunaan plastik dalam kebutuhan sehari-hari menjadi salah satu penyebab dari permasalahan lingkungan yang patut untuk di minimalisir. Sampah penyumbang terbesar ini karena sifatnya sulit terurai atau tidak mudah terurai. Daur ulang sampah sudah tak terpakai material jenis baru (komposit) dapat dilakukan sebagai usaha meminimalisir penimbunan menyebabkan lingkungan. Dalam peneliti...

Currently, materials flow optimization and creating of optimal job scheduling are one of the main tasks of all company for increase of competitiveness. A schedule problem in a manufacturing company is characterized as jobs sequence and allocation on machines during a time period. The first part of this article is focused on dynamic scheduling and its methods. The second part describes a case st...

Devices and materials intended for clinical applications as medical and implant devices should be evaluated to determine their biocompatibility in physiological systems. This article presents results from cytotoxicity assay of L929 mouse fibroblasts culture, tests for skin irritation, intracutaneous reactivity and sensitization, and material implantation tests for the novel copper/low-density p...

Polycyclic aromatic hydrocarbons (PAHs) on virgin polystyrene (PS) and PS marine debris led us to examine PS as a source and sink for PAHs in the marine environment. At two locations in San Diego Bay, we measured sorption of PAHs to PS pellets, sampling at 0, 1, 3, 6, 9, and 12 months. We detected 25 PAHs using a new analytical method with comprehensive two-dimensional gas chromatography couple...

Accumulation of low-density polyethylene (LDPE) has caused a threat to the environment because its stable and inert nature as it cannot be degraded easily by microorganisms. Its lightweight, low cost, strength, durability, various other applications, have led wide usage polymer, which is exerting negative effect on both marine land biota. The development an eco-friendly or promising strategy ne...

Using biocomposites containing wheat straw (WS) and synthetic polymers like polyethylene (PE) has gained tremendous popularity, but its application in the packaging industry is not substantial. Due to the prevalence of raw WS color which manifests itself in the WS/LDPE biocomposite, the present investigation is dedicated to fabricate a bleached WS/LDPE composite. Thus, raw WS and the pulp of WS...

this article reports a study of the thermo-oxidation and biodegradation in the soil of low-density polyethylene/starch films (ldpe/starch) by infrared spectroscopy: films of ldpe/starch blends of different composition (starch content range from 0 to 15% w/w),were prepared and exposed to thermo-oxidation at different temperatures at 80, 90 and 100°c,and buried in the soil of public dump during 3...
