Published: June 2020

Abstract
Coastal area in Mentawai Islands has natural diversity ranging from coral reefs, great waves for surfing and the beauty of the beaches. However, facilities, infrastructure and human resources are still limited. Facilities and infrastructure are the most important things in developing a tourism. This research was conducted to determine the character of the landscape, potentially of constraints and analysis of user behaviour, perception and provide design recommendations for ecotourism development on Jati Beach in North Sipora Island. The method used the physical-biophysical, social, economic, cultural, tourism, oceanography, and conservation approach aspects using quantitative and qualitative descriptive analysis. The basic concept of the site is Arsa Metarpa is an extension of Arat Sabulungan and 3 principles of nature conservation efforts in Mentawai, metanoia, catharsis, and paripatia which are adaptations of the Mentawai indigenous beliefs in preserving the environment to develop aspects of conservation, education and recreation. The resources are flat landforms, typical Jati beach plants such as Barringtonia and pes-caprae coastal plants formation. The design concept that applied in the site is transformation from one of the symbols of the Mentawai, jaraik. Jaraik is a traditional element of Mentawai, commonly used in uma’ as welcoming. Its distinctive shape is transformed into the circulation pattern and the pattern of landscape elements in the site. The output of this research is limited to the landscape design phase, with the final product as site plan and other supporting technical drawings that can be used in design reference in the landscape of the ecotourism coastal in Jati beach.

Abstract
Life cycle analysis (LCA) is a powerful method to quantify impacts based on material input in the process production. The results of midpoint impact analysis categories vary from global warming potential to water footprint. In addition, endpoint impact analysis also provides quantitative results of general environmental impact assessment which is possible to be written as additional results and a deeper analysis in Government or Company Environmental Report. There are many types of software that can be used for impact analysis, for example, SimaPro, OpenLCA, Gabi, Umberto, etc. In this study we analyze the difference of impact assessment result using Simapro and OpenLCA with same material input data and similar database. The results of the environmental impact analysis using the CML-IA baseline V3.05 / EU25 method in the SimaPro software after normalization are as follows: global warning impact contribution 0.0206, ozone layer depletion 0.0002, acidification 0.0016, and eutrophication 0.0134. Meanwhile, the analysis results from OpenLCA software after normalization are: global warming impact contribution 4,5071 × 10−13, ozone depletion 1,0794 × 10−14, acidification 3,2878 × 10−13, and eutrophication 8,4541 × 10−13.

Published: June 2020

Abstract
Bioethanol is one of the most interesting biofuels in Indonesia. In the recent years, various research studies on bioethanol production have been reported. The main problem using bioethanol as alternative energy is the refining process. In this paper, we report on our effort to increase the purity of bioethanol. The effects of different entrainer combinations were investigated. Based on our study, we found that the double entrainers combination generated better ethanol purity compared to a single entrainer. Among the possible combinations of entrainer, the combination of 10% (v/v) n-Heptane on cyclohexane-n-heptane could increase ethanol purity up to 87.39%.

Authors: Wibawa B S S , Iswara A P , Boedisantoso R 
Published: June 2020

Abstract
The electricity production using coal starts with the process of transforming heat energy into mechanical energy which drives turbines and generators to produce electricity. These activities produce emissions that can cause environmental impacts. Air pollutants causing impacts generated by coal power plants are mainly CO2, CH4, N2O, SOx, and Particulate Matter (PM). These emissions may increase global warming and decrease air quality which affects humans and the environment. This study identifies the impacts that occur from the activities of electricity production with coal using the Life Cycle Assessment (LCA) approach. LCA is an analytical method that is used to evaluate and compare the environmental impacts of a product. Identification of environmental impacts was carried out using the SimaPro 8.5.2 software. The cycles of coal production activities analyzed include coal bunkers, coal mills, boilers, turbines, and generators. The results of emission calculation, obtained in the production process of the steam power plant boiler unit at one of the coal power plants in East Java, are as follows: 1,085 kgCO2/kWh; 1,01 × 10−5 kgCH4/kWh; 1,52 × 10−5 kgN2O/kWh; 3,18 × 10−4 kgSOx/kWh; 1,12 × 10−4 kgNOx/kWh; 1,19 × 10−5 kgPM/kWh.

Abstract
This study of supply and demand of water in Surabaya City evaluates the equilibrium of domestic and non-domestic water demand with the existing supply so that the source flow rate can be prepared for the demand in the following 20 years. PDAM Surabaya has reached water service area of 96.67% and will increase to 100 percent in the following year as targeted by the Central Government. The method used was water balance of PDAM Surabaya planned for every five years until 2039. The result of this study showed the potential of raw water from Umbulan with 1,000 L/s and from Kali Brantas with 1,000 L/s. Projection for water demand for the first water balance in year 2024 resulted 15,037 L/s and there was a deficit of 3,062 L/s. The result of water balance in 2019-2039 showed that the supply would not fulfil the water demand.

Published: June 2020

Abstract
Results of an experimental investigation on shear-critical responses of small-scale reinforced concrete beams fabricated with normal concrete (NC) and concrete blended with supplementary materials using Class F fly ash (SMFA) are presented. The beams were reinforced with adequate stirrups as per requirement specified in design specifications. The beams were tested using Ohno beam testing setup to induce direct shear mechanisms across the shear plane. It was also intended to evaluate the shear capacity of a disturbed region (D-region) where the flexural moment was negligible. It was found that all beams fail in brittle shear manner, showing a significant increase of shear forces with a subtle increase in beam deflection. It was also found that the use of adequate stirrups could cease the localised crack formation. In overall results, it was found that the use of Class F fly ash as cement replacement was applicable because the response did not differ significantly.

Published: June 2020

Abstract
Two small-scale reinforced concrete beams, one made of ordinary Portland cement (NC) and the other blended with supplementary material using fly ash (SMFA), were investigated to gain insights into their flexural behaviour. Class F fly ash by 15 per cent of the mass of cement was added in the concrete mix of SMFA beam, enabling the reduction of cement usage. The specimens were designed under-reinforced having low steel bar ratio and were tested under four-point bending to failure. To ensure the beam failing in flexure, the M/Vd ratio of 3.2 was customary to allow the development of flexural cracks transpired over the centre span as the load further increased. Predictions incorporating manual calculation and computer simulation using Response-2000 were also performed and compared against the experimental data. The results showed that the NC and SMFA beams were generally equivalent in terms of load-deflection response, crack pattern, and mode of failure. Nonetheless, it should be marked that the load-carrying capacity of the SMFA beam was 22 per cent higher than that of NC beam, while the deflection of the SMFA beam was found to be significantly higher. Predictions from the manual calculation and computer simulation using Response-2000 were also in good agreement with the results obtained from the experiment.

Published: June 2020

Abstract
In this study, we developed a polymer inclusion membrane (PIM) using the phase inversion technique, based on polymer supports polyvinylidene fluoride (PVDF) and polyvinylpyrrolidone (PVP), with chitin as extractive agent (EA). This PIM was used to study facilitated extraction and recovery processes of Astrazon Red FBL 200%, Blue P3R, Direct Turquoise FBL 400% and BEMACID Yellow N-TF dyes from simulated aqueous textile solutions. To explore the composition, structure and morphology of the developed PIM, both FTIR and SEM techniques were used. To explain the performance of the PIM and describe the mechanism of the process studied for the recovery of dyes from simulated wastewater, kinetic and thermodynamic models were also adopted, which are based on Fick’s laws and the saturation law of EA by the substrate (dyes). The overall data indicate that the used EA is effective for theses oriented processes, and the facilitated extraction of dyes is not depending on the pore size but on structures and interactions between the molecules of the EA and the dye.

Published: June 2020

Abstract
The removal of textile toxic contaminants is an essential process to provide clean water to the increasing population rate. It requires a design of a selective material to adsorb dyes pollutants with stability, effectiveness and reusability. Regeneration efficiency and recovery extent (RCE) are one of the critical factors to measure the performance of the adsorption process. In this study, magnetic Core-shell beads based on porous carbon@Fe3O4 NPs with high specific surface area were successfully synthesized by simple Co-precipitation method. The structural, textural, chemical and morphological proprieties of the prepared materials were studied by XRD, FTIR, Raman spectroscopy, nitrogen adsorption-desorption, XPS, SEM and TEM. The adsorption kinetic and isotherm data were well fitted to the pseudo-second-order and Langmuir models. Magnetic particles exhibited an excellent ability to adsorb methylene blue (MB) from aqueous solutions with maximum MB adsorption capacity of 180.42 mg/g (porous carbon@Fe3O4-NPs powder) and 49.66 mg/g (magnetic Core-shell beads based on porous carbon@Fe3O4-NPs).
The synthesized core shell adsorbent showed good magnetic response, high regeneration efficiency with excellent recovery extent. We believe that in the near future these new magnetic Core-shell beads based on porous carbon@Fe3O4-NPs can be used as an alternative to solve the separation problem involving the material pollutant interfaces and can be commercialized as a benchmark adsorbent for the removal of toxic dyes.

Published: June 2020

Abstract
In this study, a cellulose nanomaterial (Cellulose nanofiber, CNF) was employed as solid support and stabilizing agent for the highly active cobalt nanoparticles via in situ green and facile synthesis as an environmentally benign supported catalyst. The process of preparation involves the reduction of cobalt precursors on the surface of CNF in ambient conditions with the presence of NaBH4. The structure of the synthesized organic-inorganic hybrid Co/CNF was characterized by field emission scanning electron microscopy, energy dispersive spectroscopy and Fourier transform infrared spectroscopy. The hybrid aerogel nanocomposite Co/CNF demonstrated excellent catalytic activity for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) in water with NaBH4. Even with a very low amount of catalyst and was found to be good enough to achieve 100% reduction of 4-NP with a higher reaction rate (in 8 min). The heterogeneous nanocomposite catalyst was easily isolated from the reaction mixture by simple filtration and reused 5 times without significant loss of its catalytic activity.
Synthesis of BaCO3 particles tailored by carboxylated cellulose fibers
Authors: Jada A , Ladhari S , Jradi K 
Published: June 2020

Abstract
The present work deals with the use of carboxylated cellulose fibers, thereafter called Cellulose Nano Fibers (CNF), as eco-friendly materials and sustainable resources for remediation and valuation, of metal ions present in contaminated water. Barium divalent cation (Ba2+) is among the most common heavy metal pollutants found in water such as arsenic, cadmium, chromium, copper, nickel, lead and mercury. Thus, CNFs containing carboxylate groups were first prepared by the oxidation of the cellulose fibers using the NaOCl-NaBr-TEMPO system, and thereafter, they were used as adsorbent for Ba2+ ions removal from BaCl2 aqueous solutions. Such Ba2+ removal was evidenced by the decrease of both the CNF surface charge and the CNF absorbance, upon the addition of the metal divalent cation, BaCl2 to the CNF aqueous dispersions. It is shown that the interaction occurring between the fiber carboxylic groups and the positively charged metal ions, Ba2+, occurs via electrostatic interactions and leads to the CNFs –Ba2+ complex formation. In the second part of this work, we investigated the effect of the CNFs on the crystallogenesis of barium carbonate particles, BaCO3. Thus, the CNFs aqueous solution was first added to barium chloride BaCl2 solution, and the mixture was stirred for a period of time (complexation time), prior the addition of sodium carbonate (Na2CO3) solution. The precipitation of barium carbonate particles in the presence of CNFs occurred at ambient temperature, in a water-jacketed Pyrex glass vessel. Finally, the resulting Barium carbonate-CNFs composites were examined by various methods such as Scanning Electronic Microscopy (SEM), and X-ray Diffraction. From the SEM data, two BaCO3 morphologies were observed, dendritic and bent or rods particles, respectively, in the absence and in the presence of the CNFs.

Authors: Ait El Fakir A , Anfar Z , Jada A , El Alem N. 
Published: June 2020

Abstract
The present work deals with the degradation in water of organic dye such as Orange G by using sulphate radicals as oxidant. Thus, a new catalyst based on polypyrrole coated hematite sand particles, (HS@Ppy) was first prepared. Thereafter, sulphate radicals were produced by activating the persulfate (PS) agent in the presence of the HS@Ppy catalyst. The resulted HS@Ppy/PS system was finally mixed with Orange G aqueous solutions for dye degradation. The data indicate that polypyrrole shell coating amount in the HS@Ppy particles has a great influence on the Orange G degradation. The HS@Ppy/PS system exhibited the highest OG removal rate (the removal rate is 98 % after 15 minutes of reaction) as compared to the various systems: PS alone, HS@Ppy alone, or HS/PS alone.

Published: June 2020

Abstract
Piezoelectric polymer-ceramic composites are promising materials for Sensing, Wireless electronics and actuating applications. We report the fabrication of highly piezoelectric biocompatible films containing lead zirconate titanate (PZT) ferroelectric ceramic particles dispersed in poly lactic acid (PLA) with different volume fractions using a solvent cast technique. The properties of the piezoelectric polymer-ceramic films were investigated by Fourier transform infrared spectrometry (FTIR) and field emission scanning electron microscopy (FE-SEM). In the FTIR spectra appear a large number of absorption bands which are attributed to the phases from PLA matrix confirming the total embedding of PZT filler into the matrix. The SEM results showed a good distribution of fillers in the matrix. We find that the added PZT imposes a significant effect on the α–β phase transformation. Our finding can lead to extraordinary enhancement of piezoelectric properties for the PLA/PZT composite films. Keywords: Piezoelectric polymer-ceramic, PLA, PZT, solvent cast technique.

Abstract
Smart textiles can detect, react, and adapt to various stimuli; they offer promising perspectives in occupation health and safety (OH&S). The objective of this study was to identify technologies, solutions, and products based on smart textiles and flexible materials that could have an application in OH&S and provide a response to some of the current needs. The collection of information included three aspects: 1) technologies, solutions, and products involving smart textiles and flexible materials found in the literature over the period 2000-2016; 2) issues in OH&S associated with traditional textiles and flexible materials; and 3) current or foreseeable problems associated with the use of smart textiles and flexible materials in OH&S. Issues with traditional textiles and flexible materials in OH&S were cross-matched with technologies, solutions and products relevant to smart textiles and flexible materials. This allowed us to propose short, mid, and long-term developments that could provide a response to some of the current needs in OH&S. The analysis shows that smart textiles and flexible materials offer a promising response to current challenges observed with PPE used in OH&S. With manufacturing and R&D capabilities available in various countries, the feasibility of development of these solutions is very high.

Published: June 2020

Abstract
The wool processing sector in Romania experienced a regression in terms of fiber quality after 1989, caused by a combination of factors: uncontrolled crossbreeding, low area and low quality pastures and lack of support for sheep breeders. As a result, the spin ability limit of the Romanian wool has decreased, as well as the possibility of using it in the textile industry, in the conditions of increasing demand for fine fabrics and knitwear, leading to the closure of many traditional textile companies and the use of imported wool. Under these circumstances, the use of the Romanian wool for related fields such as construction is much more important, as an efficient and viable alternative for recovery and an alternative for revitalization of several economic sectors. The paper presents aspects regarding the textile valorization of the thick Romanian wool varieties in order to produce materials with the role of insulation and sealing, in the field of eco-friendly constructions.
