Published: January 2020

Abstract
In this work, lithium bismuth aluminium borate glasses doped with different concentration of Er2O3 were prepared to investigate the physical, chemical group, optical and luminescence properties. All glasses were prepared by melt-quenching method. Glass density is in a range of 3.20 – 3.27 g/cm3 with no obvious relation to Er2O3 concentration. The FTIR spectra confirm the trigonal BO3 and tetrahedra BO4 borate unit appearing in glass network. This BO4 unit and non-bridging oxygen tend to increase with increment of Er2O3 content. Er3+ in glass absorb photon in visible light and near-infrared region, confirmed by the absorption spectra. The emission and excitation spectra perform the infrared emission of Er3+ under 523 and 977 nm excitation. The strongest emission with 1536 nm belongs to 1.00 mol% Er2O3 doped glass that was excited by photon with 523 nm. This developed glass possesses the good potential for using as the source and medium material for infrared emitting and communication device.

Particulate matters with the diameter less than 2.5 µm or PM2.5, have been known to the health adverse. The developing of a measurement system of PM2.5 with a high precision has become a challenge in the last decade. We design the system using a NOVA SDS011 sensor to measure PM2.5 concentration. The problem is that the sensor has a capacity to measure particulate matter in the range of 0.3 to 10 µm, meanwhile we would like to design the measurement system of PM2.5 with the high precision. Another this that we address is how to optimize the sensor. A factor influenced the sensor optimization is a sample compartment. In this paper, we present the PM2.5 measurement system with the different compartments. The PM2.5 measurement system was calibrated using the 3443 Kanomax dust monitor. The result shows that the system works well with the compartment is important factor to increase the precision.

Published: January 2020

Abstract
Air pollution caused by motor vehicle exhaust emissions produced gases such as carbon monoxide (CO) and hydrocarbon (HC) that are dangerous for health of living things. Those gases can be adsorbed with activated carbon made from agricultural waste such as banana peel because it has quite high lignocellulose content and available in large amount in Indonesia. Activated carbon from banana peel in this research was used the AC made in previous studies which has 617 mg/g and 614 mg/g surface area for chemically activated AC and chemical and physical activation combined respectively. The characterization of activated carbon was done by Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDX) tests which resulted that the pore on AC surface was visually clear and the AC contained up to 88% of carbon, respectively. Chemical-activated carbon with H2SO4 6 N was capable of adsorbing 40.46% CO and 31.51% HC respectively. While physical-chemical activated carbon with H2SO4 6 N was capable of adsorbing 56.27% CO and 42.63% HC. The banana peel waste was proven to be a promising adsorbent raw material to reduce pollutant contents in environment.
The Oxidant Effect of Bisphenol A (BPA) Can be Decoupled from its Endocrine Disruptor Property
Authors: Wisesa I B G R , Sukoco H , Siswanto F M 
Published: January 2020

Abstract
Bisphenol A (BPA) is an environmental defilement released mainly from polycarbonate plastic and epoxy resins. The main toxicological impact of BPA is its endocrine disruptor activities. Its structural features confer the ability to bind to both estrogen receptor (ER) subtypes. Furthermore, we recently reported that BPA aggravates male reproductive hormones. In addition to its endocrine disruptor properties, we have also reported that BPA possesses oxidant activity which is able to trigger oxidative stress. Several types of research previously reported that oxidative stress may cause hormonal imbalance and vice versa. However, the relation of both the toxicological properties of BPA is poorly understood. In this study, we found that oral testosterone undecanoate treatment in BPA-induced rats does not prevent decreasing serum superoxide dismutase, glutathione peroxidase, and catalase, and increasing serum malondialdehyde. Oral N-acetyl cysteine (NAC) in BPA-induced rats also does not attenuate decreasing total testosterone levels. These results suggest that the oxidant effect and endocrine disruptor property of BPA can be separated and might not interfere with one another. Therefore, future treatment in any pathological condition resulting from BPA exposure has to be carried out with more comprehensive approaches rather than focusing on its endocrine disruptor activity.
