High Density Polyethylene (HDPE) is a type of plastic that widely used for packaging because it has good mechanical properties. HDPE is naturally non-biodegradable, and the consequence it will increase plastic waste that will damage the environment. To increase their biodegradability, it is necessary to add an oxo-biodegradation additive in the form of a stearate metal compound. This oxo-biodegradation additive is a chromophore that can absorb UV light. Polyethylene oxo-biodegradation films are prepared by mixing HDPE and cobalt stearate to homogeneous on various compositions. To know the effect of adding cobalt stearate into HDPE has done by photodegradation process. The polyethylene oxo-biodegradation film was given irradiation using UV light in the wavelength range 280-300 nm at room temperature for 10 days. After irradiation, in the ATR spectrum shows an absorption peak at 1712 cm-1 wavenumber indicatied the presence of a carbonyl group with a stronger intensity. The higher concentration of cobalt stearate added in HDPE, increases the peak intensity of carbonyl group. This is due to the increasing number of chromophores from cobalt stearate that can absorb UV light, the faster the breakdown of HDPE chains into small fragments so that HDPE is rapidly degraded in nature.

Teak sawdust is a waste of the furniture industry. The main compound content is cellulose, which contains hydroxyl groups so that can be used as adsorbent. This work aims to determine adsorption capacity and isotherm adsorption pattern of teak sawdust activated by EDTA for copper (II) dan chromium (III) ions. Some parameters were optimized including the ratio of adsorbent and EDTA, and contact time. The results showed the optimum ratio of teak sawdust and EDTA was 2:3, and the optimum contact time was 105 minutes. Both of isoterm adsorption patterns of teak sawdust to Cu (II) and Cr (III) ions follow the Freundlich equation, with determination coefficient close to one. Optimum adsorption capacity was obtained 46.5 and 39.7 mg/g for Cu (II) and Cr (III), respectively.

In this study, bentonite was used as a filler in the synthesis of polylactic acid (PLA) nanocomposite. The mechanical property of PLA-Bentonite nanocomposite was treated using two different surfactants, namely octadecyl amine (ODA) and trimethyl stearyl ammonium chloride (TSC) at two different concentration (20 mmol and 40 mmol). The treatments of ODA and TSC in the matrix with regards to the basal spacing of bentonite stacks measured by X-Ray Diffraction (XRD) analysis. The results showed a significant increase in basal spacing was obtained when TSC 40 was applied for treatment. Data of Fourier Transform Infrared Spectroscopy (FTIR) suggested that this increase was caused by the incorporation of surfactant into the bentonite stacks. Most of the PLA-Bentonite nanocomposite can form intercalation structure, while a sample containing TSC 40 formed exfoliation structure. This exfoliation structure resulted in a film with the best tensile strength and water vapor permeability compared to the others. The film containing TSC 40 showed the lowest reduction in water activity, almost similar to the bread sample wrapped using conventional plastic. The bread wrapped with TSC 40 film was not grown by fungi as opposed to the conventional plastic, showing the potential of the nanocomposite film as food packaging.

Published: August 2024

Waste from the textile industry is considered as a potential source of environmental pollution, especially water because it contains dangerous dyes. In this research, natural zeolite is used as an effective and efficient alternative adsorbent to overcome pollution caused by methylene blue and methyl orange dyes. Activation of natural zeolite was carried out with 3 M HCl solution and was characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). While the methylene blue and methyl orange adsorption processes were studied in variations in the weight of the adsorbent, contact time, and pH. The concentration of dyes left in the solution was observed with Spectrophotometer UV-Vis. The results showed that the adsorption capacity of natural zeolite in absorbing methylene blue was 21.189 mg/g and methyl orange was 18.208 mg/g. The optimum conditions of methylene blue and methyl orange adsorption are achieved with successive adsorbent weights 0.3 g and 0,4 g, successive contact times are 60 minutes and 90 minutes, and successive pH are 6 and 2 respectively. The adsorbent weight factor, contact time, and pH have an effect on the adsorption of methylene blue and methyl orange by natural zeolite from Ende.

Lycopene is a red pigment found in tamarillo with its function as an antioxidant that protects body cells from the negative effects of free radicals so that they do not trigger diseases, especially cancer and premature aging. This study was intended to improve the quality of tamarillo by isolating lycopene from tamarillo through an extraction process with chloroform as a solvent by maceration for 3 days at room temperature. The lycopene extract obtained was dissolved by means of a rotary evaporator at 40 oC under vacuum pressure and oven temperature at 60 oC. The lycopene obtained was analyzed by Gas Chromatography-Mass Spectrometry and the crystal structure of lycopene was characterized by Fourier Transform Infra-Red Spectroscopy. GCMS results showed that 0.21 g of lycopene was successfully isolated from 100 g of dried red tamarillo fruit powder. Functional group analysis using FT-IR at a wavelength of 978.23 cm-1 showed the R-CH=CH-R group; the -CH3- group of 1371.43 cm-1; the 1460.16 cm-1 indicates the bending vibration of -CH2-; the C=C chain of 1656.91 and 1745.64 cm-1; and the C-H of 2856.67 and 2926.11 cm-1 of the lycopene chain.

Published: August 2024

Styrofoam waste is difficult to be decomposed by bacteria or microorganisms. Therefore it takes a long time to be decomposed naturally. Styrofoam waste, in general, is a big problem for the survival of living things on earth because there are quite a lot of them. So, if not handled properly can cause environmental pollution. Styrofoam waste is inorganic waste composed of polymers derived from chemicals. Additives from styrofoam are harmful to humans because they are carcinogenic. This study aims to utilize Styrofoam board waste into liquid fuel. Liquid fuel from styrofoam waste has been made successfully through dry distillation and fractionation methods. The result of fractional distillation is 42.00% liquid fuel. Based on the physical properties tests that have already been carried out, including the density test, viscosity, flash point, boiling point, calorific value, and octane number, it turns out that the liquid has characteristics close to the standard gasoline fuel. The MS spectra and the GC chromatogram show that the liquid fuel consists of a mixture of hydrocarbon compounds, namely acetone 0.23%, acetic acid 0.40%, benzene 2.82%, toluene 3.56%, heptane 1.04%, 1-octene 0.26%, butyl ester 4.92%, 2,4-dimethyl-1-heptane 0.32%, p-xylene 13%, the compound with the highest composition was styrene 73.45%.
