AbstractThis research aimed to figure out the infrastructure effect on the poverty level in the Eastern Part of Indonesia. The developed research model applies an econometric approach i.e. simultaneous equation model using data panel of 16 provinces. The variables of the energy, housing, transportation, clean water, education, health, and telecommunication were used to measure the effects of the infrastructure whereas the growth and income inequality were used as the intervening variables. The result indicates that housing, clean water, and telecommunication have a negative and significant effect, while energy has a positive and significant effect on the poverty level. Indirectly, housing, clean water, education, and telecommunication variables have a negative and significant effect on the poverty level. In addition, energy and transportation have positive and significant effects on the poverty level. Another finding is improving economic growth in the Eastern Part of Indonesia causing more equal income distribution. However, it is not accompanied by poverty reduction.

Abstract
City open space is an open space within a city, commonly used for parks, green spaces, and other open areas. The landscape of the city’s open space can range from playing fields to highly maintained environments to relatively natural landscapes. In Palangkaraya city, there are many vacant open spaces located in flood-prone areas near a river stream. It has a significant function for the city environment, however, most of them are occupied illegally for settlements. Palangkaraya city is a small-medium city located in Central Kalimantan Province, Indonesia. The city is surrounded by forest 285,349.28 hectares while the size of the city itself is 168,000 hectares with a population of 376,647 people. According to Burgess, a small-medium city is a city with a population of more than 100,000 people but a little bit less than the minimum number of the population categorized as a medium city which is 500,000 people. The use of the vacant open spaces in flood-prone areas in such a small-medium city like Palangkaraya city is mainly for environmental function. This research will measure scientifically the use of the vacant open spaces in flood-prone areas for environmental function, hence city policy on the development of city open spaces can be formulated to increase benefits from the existence of city open spaces within a small-medium city.

Abstract
A livelihood strategy is fundamental in the lives of residents, including torani fishermen as an effort to survive or improve their standard of living. The sustainability of the torani fishermen’s livelihood pattern is related to the social formation in the mode of production (production power and production relations) that takes place. This research aims to analyze the relationship between the mode of production with a livelihood strategy that is carried out for the sustainability of torani fishermen in Takalar district. This research develops a pospositivistic paradigm of descriptive research through a qualitative method using a case study design. Data was collected and analyzed according to the instructions of qualitative research through three stages of activities, namely 1). Data reduction 2). Data exposure and 3). Conclusion and verification. The results of the study indicate that the mode of production that takes place in the torani fishing community is the capitalist mode of production and the non-capitalist mode of production, where the capitalist mode of production dominates the non-capitalist mode of production. The two modes of production provide different income results and become the basis for making a choice of livelihood strategies. Some choices of livelihood strategies that have been carried out are survival strategies, consolidation strategies, accumulation strategies and diversification strategy

Authors: Loto Roland T. 
Published: May 2020

AbstractThe corrosion resistance of as-received 409 ferritic, 430 ferritic, 444 ferritic and 316 austenitic stainless steels was studied in 0.05M H2SO4/3.5% NaCl solution by potentiodynamic polarization and potentiostatic measurement and compared to their counterparts subjected to repetitive temperature variation at 1000°C. As-received 409 ferritic steel exhibited the highest corrosion rate at 8.406 mm/y compared to as-received 316 austenitic steel with the lowest corrosion rate at 3.130 mm/y. Corrosion rate of heat treated 409, 430 and 444 ferritic stainless steels significantly increased to 10.766 mm/y, 5.694 mm/y and 6.096mm/y while the corrosion rate of as-received 316 austenitic steel decreased to decreased to 0.409 mm/y. As-received 444 ferritic steel exhibited the weakest resistance to pitting corrosion while as-received 409 ferritic steel exhibited the most significant metastable pitting activity. Pitting corrosion susceptibility of heat treated 409 ferritic, 316 austenitic and 444 ferritic steel decreased significantly to 0.137 V, 0.384 V and 0.096 V while heat treated 430 ferritic steel exhibited significant improvement in pitting corrosion resistance.

Published: May 2020

Abstract
The mass loss of three wood species in Malaysia, Shorea laevis, Koompassia malaccensis, and Shorea parvifolia were measured against time and temperature at three different heating rates (5, 10 and 20 °C/min) in nitrogen environment, through thermogravimetry analysis (TGA) technique. This measurement revealed that the decomposition of these wood generally occurred in three stages, the dehydration stage, the active stage, and; the passive stage. The maximum decomposition peak in derivative thermogravimetric (DTG) analysis curve shifted towards higher temperature range with the expedition in heating rate. The kinetic decomposition parameters of the timbers were determined by adopting thermal kinetic method of Coats and Redfern. Principally, the density and moisture content of timber does not influence the kinetic parameters studied in this work. Overall, the thermal decomposition in the second-stage (active stage) was dominated by the hemicellulose and cellulose while the decomposition of lignin was apparent in the third-stage (passive stage) of pyrolysis. The higher activation energy in the second-stage indicates that more cellulose is contained in the sample. The activation energy of lignin is observed to be much lesser compared to the activation energy of the hemicellulose and cellulose for two species tested except for the Shorea parvifolia.

Published: May 2020

Abstract
Silica aerogel-based thermal insulation coating (SA-coating) was prepared from a commercial acrylic binder. The purpose of this investigation is to determine the effectiveness of SA-coating with the application in energy-efficient home design for temperature insulation purposes. The weather acceleration test and thermal insulation property of SA-coating were investigated and compared to the original commercial binder. The weather acceleration test of SA-coating showed equivalent weathering stability and robustness compared to the original binder. The thermal insulation property was performed from an in-lab setup, called temperature difference (TD) measurement. In a closed chamber, without air circulation, the surface temperature with SA-coating was reduced by as much as 26 degrees from 90°C to ∼64°C. More so, if TD measurement was performed in a ventilated area, the temperature can be reduced from 50°C to 36°C (room temperature was 31 °C). The thermal conductivity of the coating at different temperatures was also measured. The water contact angle measurements and the scanning electron micrographs showed that SA-coating can be made hydrophilic to hydrophobic by simple abrasion.

Abstract
In luxurious glass buildings and constructions, heat gain (or heat loss) mostly comes through the windows. Infrared (IR) radiation is an important factor that causes the entry of heat into the buildings. To save energy consumption of air conditioners, low-emissivity (Low-E) glass coating applications are focused. In the energy-saving field, transparent conductive oxide (TCOs) are used as coatings to minimized IR entry. In this work, copper-doped zinc oxide (CZO) is synthesized for thermal reflective material. Cu(II) ions are doped to ZnO by a sol-gel method to obtain CZO nanoparticles and is coated on a glass substrate. The morphology of CZO is investigated with scanning electron microscopy (SEM); phase crystallinity is determined by X-ray diffraction (XRD); and UV-Vis-NIR spectroscopy is used to characterize UV/IR-shielding and also the optical transparency. IR cameras and in-lab thermal insulation setup are used to test the heat insulation properties. The result shows that 15% copper-doped zinc oxide has the best insulation from IR rays with the lowest temperature in the interior (T3) of 50.6°C while the outer temperature (T2) was at 85.5°C the lowering of the temperature by 34.9°C (cooler by 59%). CZO synthesized from the sol-gel method has promising properties for Low-E glass coating applications.

Published: May 2020

AbstractBlends of polyamide 6 (PA6) and, polybutylene terephthalate (PBT) have been prepared in this work. They were compatibilized using epoxidized natural rubber (ENR-50) by varying amount of ENR-50 i.e., 0, 3 and 5 phr. The effect of blend compositions and compatibilization on the phase morphology and properties of the resulting blends were investigated using a scanning electron microscope, universal testing machine, impact testing machine, and hardness shore durometer. All blends were prepared and shaped by using twin-screw extruder at 260°C and injection molding machine, respectively. The results revealed that the phase morphology of the PA6/PBT blend was incompatible. The separation of PA6 and PBT was observed wherein PBT is dispersed in the form of spherical domains in the PA6 matrix. The mechanical properties exhibit loss in tensile and impact strength. This could be attributed to poor interfacial adhesion between the two polymers. SEM micrographs showed that the addition of ENR-50 improved the compatibility of PA6/PBT blends. With the addition of ENR-50 as a compatibilizer, the uniformity and the maximum reduction of dispersed phase sized were achieved. The water absorption of PA6/PBT blends decreased with an increasing amount of PBT. Additionally, the results indicated that, as the amount of ENR-50 increased, the mechanical properties, including tensile stress at peak, tensile modulus, and izod impact strength were improved.

Abstract
This presented work was to study mechanical and tack properties of unvulcanized rubber tapes made from STR 20 and IR 2200 with various amount of carbon black and rosin as reinforcing agent and tackifier, respectively. Mixing process of solid rubbers and all chemicals was carried out by two roll mill machine. All rubber compounds were subjected to increasing the stickiness by aging under hot air at 150°C for 3 hours. From the experiment, green strength of the sticky rubber tape mixed with carbon black and rosin showed higher than that of the commercial rubber tape. The formulation exhibited the highest tensile stress at 400% strain is STR 20 mixed with 15 and 5 phr of carbon black and rosin, respectively. Mooney viscosity of the rubber tape made from STR 20 and IR 2200 was also reduced with the higher content of rosin. Although Mooney viscosity of the adhesive rubber tape normally decreased after heating under hot air, its tack property investigeted by rolling ball test on the surface predominantly became increased. Moreover, Mooney viscosity of the rubber tape made from IR 2200 would be remarkably enhanced by blending with only 20% of STR 20.

Authors: Fahada Adil 
Published: May 2020

Abstract
The network traffic classification is used as a basis of network management related works, from security monitoring and Intrusion Detection Systems (IDS) to Quality of Service (QoS). Many works have been carried out on this theme that proposed various approaches. Most of the proposed approaches utilize predefined class label provided by an expert to perform the network traffic classification. Nevertheless, the difficulty to acquire consistent, adequate and up-to-date ground truth for classifying network flows effectively is still as serious problem. This work addresses such an issue via multi-view stacking to fuse the metadata from heterogeneous types of semi-supervised classifiers for accurate classification thru the following steps. Firstly, the original data is represented as multi-view using dimensionality reduction methods, with the aim to have strong discrimination capability. Secondly, integrate different semi-supervised learning algorithms from an ensemble learning perspective, to deliver a better stability and quality classification output. Finally, propose N-fold cross validation on metadata for training the meta-classifier, to produce the final class decision and predict the unlabelled traffic data. Experiment results on four existing network traffic datasets provide the best average accuracy mark is above 96% on all datasets and the best stability performance is up to 99.50%.

Published: May 2020

Abstract
Rosemary oil was investigated on carbon steel in 0.5M sulphuric acid through weight loss technique. It was observed that weight loss, inhibitor efficiency and corrosion rate differ in concentration of the oil and exposure time. Maximum inhibitor efficiency of 78.45% was obtained at 10ml concentration of the oil. The performance of the oil was associated with the existence of organic compounds such as alkaloids, flavonoids, tannins, among others which form a protective film and act as a barrier against corrosion attack in sulphuric acid environment.

Authors: Rusdi S , Ma’mun S , Qifari M Y , Gite R D V 
Published: May 2020

Abstract
Acid protonation constant (Ka) is one of the parameters required for thermodynamic modelling. In addition, a rigorous thermodynamic model requires solvent non-ideality properties in order to have a better model representation. This study aims to evaluate species activity coefficients from potentiometric titration data of the MEA-H2O system at temperatures ranging from 303 to 333K. The results show that the activities of the free MEA and the protonated MEA depend on pH. In addition, the activity coefficients of the protonated MEA determined by the extended Debye-Hückel model were less than unity at different temperatures. This means that the system observed was the non-ideal one.
