Published: July 2020

Abstract
The mission goal of the Working Group for Sustainable Development Goals (WG4SDG) of the Hungarian Society of Surveying, Mapping and Remote Sensing (MFTTT) is to promote the use of the steadily developed Earth observation (EO) and geospatial data infrastructures (SDI) and services – considering as base elements of the Digital Earth concept -as supportive tools for many of the SDGs-related indicator monitoring and reporting. The engagement of the stakeholders from government, academia/education, private sector/industry and learned societies is a key issue also on national level. It is anticipated, the link with the forum of the EO industry represented by the Hungarian Space Cluster HUNSPACE will leverage the experiences of the EO and SDI communities. Similarly, the connection with the national geographic information (GI) association HUNAGI and international societies such as FIG, ISPRS, ICA and ISDE are vital for knowledge transfer.

Mapping impact of urbanization in Shahat-Cyrene (Libya) using a big SAR data approach of change detection with COSMO-SkyMed time series
Authors: Tapete D , Cigna F 
Published: July 2020

Abstract
Uncontrolled and unregulated urbanization around the modern town of Shahat, Libya, has been reported by several studies as a pressing issue for the conservation of archaeological heritage in the cultural landscape south of Cyrene UNESCO World Heritage Site (WHS). In this paper, we implemented a big Synthetic Aperture Radar (SAR) data analysis approach on a selection of more than 180 StripMap images that the Italian Space Agency (ASI)’s COSMO-SkyMed constellation has consistently collected at 3-m resolution over Cyrene since 2011, as part of its background acquisition scenario. We prove the accuracy of the method to map the spatial and temporal spread of new building and road blocks using COSMO-SkyMed SAR data, and its complementarity with the mapping based on the full archive of cloud-free Copernicus Sentinel-2 multi-spectral imagery at 10-m resolution (2015-2017). Owing to the higher spatial resolution and half-month frequency of observation of COSMO-SkyMed, we better delineated the new urban features and estimated more precisely when these were developed across the landscape.

Published: July 2020

Abstract
Progenies from two seedling seed orchards (SSO) consisting of the same families could perform different growths. Concerning this fact, improved seeds of Eucalyptus pellita collected from two SSOs based primarily on the same families and provenances were tested together in a genetic gain trial. The study aims to observe the impact of within family seed trees in two SSOs on growth superiority of the improved seeds. The trial was established in Wonogiri, Central Java and laid out in randomized complete block design with three seed sources: SSO-A,SSO-B and one seed stand (as control), 100 trees/plot, 4 replications and 4x1.5mspacing. Measurements were conducted at seven periodical times (16 months up to 66 months of ages). Improved seeds from the two SSOs displayed better growths than that from seed stand at all measurements. The growth superiority of SSO over the control varied among the two SSO. SSO-A showed consistently higher superiority relativelythanSSO-B, on average of 110%, 236%, 122% and 165% in height, dbh, stem volume, and stand volume, respectively. The results demonstrated the importanceof within family variation of E. pellita in establishing seed orchard for seed production and further breeding.

Published: July 2020

Abstract
Shorea producing tengkawang grows naturally in Indonesia, however several species are now listed in the IUCN as endangered species. Their presences in natural forests arebecoming scarce so that it requires conservation efforts such as the construction of ex- situ conservation plots. This research aims to obtain data and information about the genetic diversity structure of several species of Shorea producing tengkawang. The material used was leaf samples from 11 (eleven) populations consisting of 4 (four) species of Shorea producing tengkawang. The method used 4 pairs of microsatellite DNA markers (SSR), and data analysis used POPGENE and GenAleX. The results show various genetic distances between populations, ranging from 0.028 to 1.510 with the value of genetic diversity in the population larger (72%) than among the populations (28%). Genetic diversity in the population ranges from 0.5269 - 0.8244. Cluster analysis shows that the existing Shorea producing Tengkawang population does not form a specific grouping. This genetic diversity information can be used as the basic data for the development of Shorea producing tengkawang ex-situ conservation plots.

Abstract
Kulim (Scorodocarpus borneensis Becc.) is one of Indonesian wood species with high economic value. Kulim wood is widely used for house construction, bridges and shipbuilding, while its fruit is used for cooking for its garlicy fragrance. Unfortunately, this species is currently rare in the wild due to habitat disturbance. Re-planting efforts require good quality seeds which can be collected from designated seed sources. The aim of this study was to identify the potential of Kulim stand in the arboretum of PT. Arara Abadi, Riau which covers 26.2 ha. Data collected from the site include tree height, diameter, geographic position as well as stand conditions. Total of 152 individual trees (121 trees, 23 poles, 5 saplings and 2 seedlings) were found in the area of study. The area is accessible, relatively safe from interference and well managed. The quality of the stands is quite good with no significant attack from pests or diseases. Fruits, seedlings and saplings were also found in the forest floor. The stand is therefore appropriate to be designated as Identified Seed Stand of Kulim based on the criteria of regulation concerning implementation of forest seeds. This stand can also be reserved as an insitu conservation area of Kulim.

Published: July 2020

Abstract
The aim of this paper is to study the effect of magnesium hydroxide burning rate, mechanical properties and surface morphology analysis of Arenga pinnata fibre hybrid with polyester yarn (APF/PET) reinforced epoxy composite with the addition of magnesium hydroxide as flame retardant. The composites were prepared with different amount of fibres (i.e. 0%, 20%, 35% and 50% by weight percent) and two constant material of 5% which are the magnesium hydroxide and the polyester yarn with epoxy resin as the matrix. With the incorporation of the flame retardant the horizontal burning rate of APF/PET reinforced epoxy decreased with the amount of 35% APF. The fibre loading increased to 50% as the mechanical properties of the hybrid composite decreased which due to the lack of interfacial bonding between the fibres and matrix. Surface morphology studies through scanning electron microscopy showed the similar distribution of Arenga pinnata fibres and matrix with less adhesion which reduce the mechanical properties of the hybrid composites.

Abstract
Steel corrosion and biofouling have adverse impacts on various high-end engineering applications including, in biomedical and maritime industries. Smart functional polymer coatings have been developed to simultaneously control corrosion and prevent biofouling problems on steels. In this study, translucent epoxy coatings loaded with 1, 3, and 5 wt% of functional hybrid composite (HC) microparticles were formulated. The HC particles contained cerium doped ZnO encapsulated in conductive poly(3,4-ethylene dioxythiophene) polystyrene sulfonate (PEDOT: PSS) polymer at mixing ratio of 3:1. The effects of HC composition towards the corrosion inhibition and antifouling properties of the coating were evaluated. The microstructure and composition analyses were performed by using SEM and EDX techniques. The anticorrosion performance of the coating films deposited on stainless steel (SS 316 L) substrates was evaluated by using the Potentiodynamic Polarization (PP) technique. The antifouling characteristics of the coatings were investigated by performing the antimicrobial susceptibility test and a series of photodegradation test in medium containing ∼108 CFU/ml of bacteria under UV light in 180 minutes. The findings revealed that the presence of PEDOT:PSS-Ce doped ZnO HC increased the barrier properties of the epoxy matrix on SS 316 L against corrosion. The corrosion inhibition properties increased with increasing HC composition. The formulated coatings also exhibited antifouling effects against bacteria. The Gram positive-S. aureus exhibited susceptibility against the coating whereas the Gram negative – S. aureus showed resistant. The coatings demonstrated photocatalytic properties under UV light irradiation and capable of inactivating <99% of bacteria in less than 180 min. The epoxy coating functionalized with 5wt% HC exhibited the highest corrosion inhibition performance (corrosion rate of 0.0001 mm/year) and excellent antifouling effects against selected bacteria.

Published: July 2020

Abstract
Palm slag in previous studies has proven to have the potential to be used as alternative filler in friction composite. However, the reported hardness is still high and not within the proper range and might cause damage to the disc brakes. As is well known, the good damping, soft and flexible nature of rubber, being the main reason for waste tire dust to be selected as an additive to reduce or moderate the hardness of friction palm slag composite. Weight percentage and the filler size of waste tire dust used are the main parameters considered in this research paper. The hardness and wear rate of the friction composite produced are measured. The result revealed that friction composite with ratio of palm slag/waste tire dust (30/10) and the highest filler size (>600 µm) give a moderate hardness with better wear rate which comparable with the commercial brake pad used. Morphological view also give a prove that the worn surface of composite have less wear defects. Overall the used of waste tire dust can improve the hardness and wear rate properties of palm slag friction composites in order to become alternative for non-asbestos brake pads.

Abstract
This paper investigates the incorporation of sodium hydroxide (NaOH) concentration and CaO-Si component on ground granulated blast furnace slag geopolymers (GGBFS). An optimal mechanical property of GGBFS with various NaOH concentrations had been determined by performing a number of compressive strength tests. It was found that GGBFS with 10M NaOH concentration resulted in high compressive strength at 65.31 MPa after 28 days curing. The microstructure analysis of the GGBFS geopolymers using SEM and FTIR revealed the formation of calcium silicate hydrate (Ca5Si6O16(OH)2.4H2O) and calcium carbonate (CaCO3) phase within the geopolymer backbone chain. The optimum NaOH concentration allows the acceptable formation of CaO-Si bond on the GGBFS geopolymers main structure and thus leads to optimum compressive strength.

Published: July 2020

Abstract
Recent research reveals that formulation of blended geopolymers based on the association of two aluminosilicate precursors had a better performance than one precursor geopolymers. This study presents a facile method to enhance the compressive strength of fly ash-metakaolin blend geopolymer by incorporating monoaluminum phosphate (MAP) during the geopolymerization reaction. The effect of the thermal exposure on the microstructure and compressive strength of the geopolymer are investigated. Results show that the MAP is transformed to granule structures, bonded and surrounded by geopolymer gel. The unique microstructure increases the compressive strength of the room temperature curing geopolymer from 54.7 MPa to 64.21 MPa (14.8%) with an optimum addition of 1.0 wt% MAP. This enhancement in compressive strength was ensured by the formation of an amorphous structure of aluminosilicophosphate (SiO2.Al2O3.P2O5.nH2O) phase. At higher temperatures, the formation of stable crystalline phase of berlinite and nepheline contribute to strength retention of the geopolymer. Hereby, it can be concluded that the addition of 1.0wt% MAP in the geopolymer reinforced the structure.

Abstract
Filtering Facepieces (FFPs) are commonly use as personal protective equipment (PPE). It is disposable Respiratory Protective Equipment (RPE). Basically it is used for protection against dusts, particles and aerosols. Available in 3 classes FFP1, FFP2 and FFP3. Various Respiratory Protective Equipment (RPE) offered in Malaysia’s market today are not being controlled and monitored by expert bodies and authorities. This has led to various perceptions among the users, especially on the quality and safety and health features of the products offered by different companies. This situation also makes it difficult for users to decide appropriate RPE based on quality and standard compliance. The tendency of consumers to choose RPE is mainly based on the price but not the technical aspect of RPE. Hence, the RPE they purchased not necessary enhance user protection, as there is no guidance available to assist user before they purchase the most appropriate RPE. This study describes market surveillance testing of FFP2 respirator from 30 different brand in Malaysia. The objective is to determine performance requirements required by the Malaysia standard. 3 types of testing were used on this study Filter Penetration, Breathing Resistance and Carbon Dioxide Content. All testing was carried out based on Malaysia Standard; MS 2323:2010 and MS2553:2014.All 30 sample were passed the breathing resistance and carbon dioxide content except 10 brand was failed the filter penetration testing. It is noticed that the user and consumer should aware with their PPE basic requirement.

Published: July 2020

AbstractSoil-structure interaction (SSI) is often disregarded to reduce difficulties in analyses. Thus, most of analyses adopted rigid foundation despite ignoring SSI could lead to inaccurate response. Current study investigates the influence of SSI on low-to medium-rise existing frames considering non-seismic loading. A multichannel analysis of surface wave (MASW) is performed at several locations in Penang to obtain shear wave velocity of local site conditions. The frames are modelled with rigid and flexible (soil flexibility) and analyzed using nonlinear static analysis. Each of the frames is subjected with seismic zone factor to predict the seismic response using Acceleration-Displacement Response Spectra (ADRS) concept. A flexible base elongated the period mainly under soft soil (soil E), increasing by up to 6.27%, 9.44%, and 4.12% for 3-, 6-, and 16-story frames, respectively. The frames that considered SSI experienced degradation of their capacity curve, strength, and stiffness. Under a dissimilar seismic zone factor, low-story frames achieved high demand, whereas high-story frames delivered maximum displacement is observed.
