The land-use and land-cover (LULC) pattern of an area is an outcome of natural and socio-economic factors and their use spatially by man; this LULC varies from the forest, water body, agricultural land and so on. Remote Sensing (RS) and Geographical Information System (GIS) studies have predominantly focused on providing the technical knowledge of, where, and the type of LULC change that has occurred and its impacts on man and the environment. Knowledge about LULC changes is essential for understanding the relationships and interfaces between humans and the natural environment. The purpose of this article is to review the previous studies of the spatiotemporal LULC changes. However, thirty (30) articles were reviewed from 2011 to 2017. However, these articles studied the LULC, classification, changes and change detection analysis, using different methods and software of RS and G.I.S. The finding shows that these articles have overall accuracy assessment ranges from 75% to 95% validations. Also, supervised classification in Maximum Likelihood Algorithm method was mostly employed for the LULC classification. Moreover, these reviewed articles confirmed that LULC changes are imminent as a result of both natural and human factors which lead to increase and decrease of one LULC cover to another. Therefore proper monitoring of LULC changes when applied help the relevant government bodies, agencies and environmental managers utilise the environment to the fullest.Â Â

Published: April 2019

This study is conducted to observe how language element gives impact to the integration of the Siamese and Malay communities in Kampung Keluang. The study is done by applying two techniques of data collection through fieldwork, namely join observation and thematic interview with the villagers in Kampung Keluang which consist of the Malays and Siamese, besides some other noteworthy individuals. The research findings showed the Siamese community use Malay language as their main language in daily undertakings and their fluency in in using the language has become an element that fosters their integration with the surrounding Malay community. Nevertheless, Siamese language is kept preserved as an identity of the Siamese through informal approach such as the socialization of parents towards their children. Preservation of the Siamese identity through their mother-tongue apparently has not given any repercussion towards integration process of the society in Kampung Keluang. The sharing of language with similar dialect, with the Malay community by the Siamese community proved that they have shared a comparable code system when interacting and it has given positive impact to the social integration in Kampung Keluang.Â Â

Published: April 2019

One of the important issues for sustainable island tourism is knowledge about the needs of the host and tourist. As tourism is now becoming a global issue, there is also a need to examine this issue from the context of a cross-culture. A better understanding of cultural dissimilarities between hosts and guests at certain areas of destinations could improve tailored services and increase satisfaction for both the host and tourists. Existing studies related to expectation mainly undertaken from the tourist view. However, this study takes into consideration the expectation of service quality from tourists’ perspectives as well as host community. This study aims to gain some understanding about the impacts of cross-cultural dissimilarities between hosts and tourists by measuring their mutual expectations. Survey data is collected from Perhentian and Redang Islands, Malaysia. Two sample groups were involved in the study: host and tourists (Malay, Chinese, English and European). This study adopted two methods - the Mann-Whitney U-test and the Principal Components Analysis (PCA). The findings of this study demonstrate that mutual expectations between hosts and guests diverge across the cultural groups. This study contributes to the existing literatures related to service quality and highlights the importance of cultural differences in providing better quality tourism services particularly to island tourists in Malaysia and elsewhere. .

Published: April 2019

Wetlands have been introduced as natural based devices for treating the stormwater runoff. Temperature plays an important role in the nutrient removal process of wetland plants. Thus, the effect of temperature on nutrient removal efficiency of the water hyacinth plant was evaluated in this study. Water quality of both tanks that containing water hyacinth plants and control tank were monitored continuously for 2 weeks. The collected water samples were examined for total phosphorous (TP), turbidity, dissolved oxygen (DO), pH, conductivity (Cond.), total dissolve solid (TDS) and water temperature. The results showed that there are changes in the water quality concentration although there is no water hyacinth in the control tank. The release of phosphorus from the organic matter and particle in the control tank is suggested that occurred during the high temperature period. The optimum removal of nutrient occurred during the water temperature at 30℃. This clearly showed the effect of temperature on the flux of phosphorus in the water tank.

Authors: Al-Bloush Hani , Solemon Badariah 
Published: April 2019

Crowdsourced Software Engineering (CSE) is an application of online problem-solving model that provides a dynamic way of harnessing crowd intelligence in obtaining creative solutions. It consists of four elements: crowdsourcer, crowd, platform, and tasks. Although CSE offers various advantages to software engineering practices, recent research highlighted that there is still a lack of thorough understanding of Intellectual Property (IP) ownership rights of CSE elements. Therefore, management and control of CSE for obtaining adequate IP from the crowd is inevitable to reduce the risks of using that IP.Â This paper reviews existing CSE platforms and analyses associated IP challenges encountered by software engineering activities. 51 platforms were preselected and amongst these, analyses were performed on 37 CSE platforms. Exclusion of 11 platforms is on the basis of unavailability and 3 of which are linked to the same webpage. It also shows that 59% of the platforms acquire IP ownership of deliverables submitted by the crowd while 19% do not have a statement which provides clarity on IP ownership in their legal documents. This paper is significant in providing better understanding of IP risks of these CSE platforms and in assisting both crowdsourcers and the crowd in choosing crowdsourcing platforms based on the default IP ownership specification, which is often specified in legal documents of these platforms.

Brick is one of largest material used in construction of infrastructure all over the world. A conventional bricks such as clay brick and concrete brick are produced from clay with high temperature kiln firing and from ordinary Portland cement (OPC) concrete respectively. Â Â Both of this activities lead to CO2 emission. The burning process requires high temperature at the same time release carbon dioxide and pollute the environment. At present, carbon emissions has become a crucial issues in the society that must be solved. Several studies had demonstrated that brick can be produced from bacteria based on Microbial Induced Calcite Precipitation (MICP). The objective of this study is to develop cement free- brick from vegetables waste with added eggshell as calcium additive to induce biocementation of brick. Brick specimen was cast in the mould size 210 x 90 x 65 mm and casting for 28 days. The study showed that there was an increased in compressive strength up to 0.062 N/mm2 as the curing period increased to 28 days which showed the occurrence of biocementation activities. SEM-EDX analysis confirmed the presence of calcite precipitation. The result indicated that vege-grout can be used as binding agent for biocementation to produce bricks.

Red algae species, Euchema Spinosum (ES) in Malaysia possesses excellent biosorbent properties in removing dyes from aqueous solutions. Studies had been made on the effect of pretreatment and reusability of this species as a biosorbent for economic viability. In the present study, physical and chemical pretreatments processes were employed on the ES. Desorption using seven different eluents (hydrochloric acid (HCl), sodium hydroxide (NaOH), phosphoric acid (H3PO4), potassium hydroxide (KOH), sodium chloride (NaCl), nitric acid (HNO3 and deionized water).Â Caharacterization of ES biosorbent was conducted using FTIR to investigate the active functional group responsible in the biosorption process. It was observed that the pretreatment process does not enhance the uptake capacity of ES.Â Among of the six eluents used, it is suggested HNO3 as an effective eluent with 51% desorption efficiency.Â Â Through regeneration study, HNO3 as eluent can promote four times of biosorption-desorption cycles. FTIR confirm the functional groups such as â€“OH, â€“NH and â€“COO- are responsible for the MB dye biosorption. The experiment displays that the ES does not require any pretreatment procedure to improve biosorption efficiency and has the capability of regeneration hence suggesting that ES is indeed an economical biosorptive material for MB dye removal.
Comparison of 2D and 3D Stability Analyses for Natural Slope
Authors: Bahsan Erly , Fakhriyyanti Rifani 
Published: April 2019

Slope stability analyses are performed mostly as a two-dimensional (2D) section under the assumption of plane strain conditions, without much consideration to the impact of three-dimensional (3D) shapes. For natural slopes that have the complexities of slope surfaces, 3D modeling may also be considered since it can represent the more realistic geometry of the slope. However, previous studies show that the factor of safety (FS) as a result of 3D analyses mostly overestimated the FS from 2D analyses. This may lead to a long discussion on whether the 3D analysis is still applicable for the natural slopes, and could it represent the same results as the 2D analysis. This study was conducted using the finite element method for calculating the 2D and 3D FS of Pasir Muncang natural slope in order to observe differences of FS resulted from both analyses. A comparison of the FS from the 2D and 3D analyses, and also verification of sensitivity on several factors that impact the 2D and 3D models have been performed. The results of this study has indicated that some factors such as soil parameters, contour interval, and mesh coarseness greatly affect the results of the 2D and 3D calculations. Having carefully selected the aforementioned factors as the inputs for calculations, the difference between the FS values of 3D and 2D analyses becomes smaller. The final result of FS for this case study from the 3D analysis was still higher than the one from the 2D analysis, with the ratio of FS from 3D to FS from 2D was 1.44. It can be inferred that the use of 3D analyses needs more accurate data selections compared to the 2D analyses.Â Â

Published: April 2019

This paper presents the experimental investigation on the effect of sintering schedule to the final properties of FeCuAl powder compacts formed at elevated temperature through a lab-scale uniaxial die compaction rig. Â Iron (Fe) powder ASC100.29 was used as a main powder constituent and mixed with elemental powders which are copper (Cu) and aluminum (Al). Â The weight percentage of powder mass was divided into four, i.e., iron (91.7 wt%), copper (7.5 wt%), aluminum (0.5 wt%), and zinc stearate (0.3 wt%) as lubricant. Â All the powders were mixed through mechanical blending at a rotation speed of 30 rpm for 30 min. Â The mixed powder mass was compacted at 150ËšC by 425 MPa of axial loading from upward and downward simultaneously. Â Subsequently, the defect-free green compacts were sintered under controlled argon gas atmosphere at three different sintering temperatures, i.e., 800ËšC, 900ËšC and 1000ËšC for 120 min, 150 min and 180 min, respectively at constant sintering rate of 10ËšC/min. Â Afterwards, the sintered samples were characterized for their physical properties, electrical properties, mechanical properties and their microstructures were evaluated. Â The results revealed that higher flexure stress was acquired by sample sintered at 1000ËšC for 120 min and their microstructures were found to be better, i.e., the particles were bonded perfectly.

Published: April 2019

The Internet-of-Things (IoT) is a wireless technology that offers opportunities for Government-Agencies (GA) to improve services to citizens. However, the challenge is to ensure that the IoT is fully utilized as the real value of using IoT services comes from the establishments of services through effective utilization of technologies. This paper aims to develop a conceptual model for successful implementation of IoT services in GA which is one of the least essential studied aspects of utilization of Digital-Government services. This study proposes a new integrated success model that combines the dimensions of Technology-Readiness-Index (TRI) 2.0 with other success factors â€“ service quality, information quality, system quality, user satisfaction, use (from DeLone&McLean Information-System-Success-Model), perceived usefulness (from Technology-Acceptance-Model), and trust construct to understand the determinants of IoT services success model in GA from the perspective of government officers. Interviews with Government-IoT experts are conducted to define and delineate the research problem. The proposed model could bring a better perspective of the critical factors that contribute to the success of IoT services implementation process particularly in GA as well as providing a groundwork for further empirical testing. Moreover, it will suggest an appropriate implementation mechanism to help GA increase the use of IoT services.Â Â

Published: April 2019

The study of prediction has drawn great interest in a wide range of field. T-Method which was developed specifically for prediction of the multidimensional case using historical data to develop its baseline model proved that making a prediction is possible even with limited sample size. The element of the signal to noise ratio (SNR) adopted into the T-Method strengthens its robustness. Orthogonal array (OA) in T-Method was used as features selection optimization in improving the analysis speed, cost and computer burden during the analysis. However, the limitation of OA in dealing with higher dimensionality and complex combination factors restraint the optimization accuracy. Artificial Bee Colony (ABC) was adopted in this study to overcome this limitation. The result of this study shows that T-method +ABC provide the best error% accuracy with only 2.45% and 2.53% (3 optimized features out of 15) compared to T-Method +OA which 2.81% and 2.67% and T-Method +Spearman Correlation as 3.16% and 3.06%. The power consumption prediction case study is a good example for cases that deal with high correlation coefficient (R2) baseline model (>0.8). If the R2 is lower than 0.8, further enhancement needs to be done to ensure a low risk of high error% prediction.Â Â

The computing devices utilized as a part of an extensive class of remote correspondence systems, for example, cell phones, remote sensor systems (WSNs), vehicular ad hoc networks (VANETs), mobile ad hoc networks (MANETs), Internet of Things (IoT), body area networks (BANs) and so on, are little and asset compelled. In the current developments of the resource constraint environments, the trend is shifted towards lightweight cryptographic algorithm. Many lightweight cryptographic algorithms have been developed and also existed algorithms are modified in terms of resource constraint environments. One of such new procedures is utilizing three prime numbers for RSA cryptosystem, which is not easily breakable. Our approach using three prime number rather than two prime-dependent systems to get (n) with same length of standard RSA but less bits for prime numbers. The suggested algorithm has speed enhancement on standard RSA key generation side and decryption side by utilizing three primes and the Chinese Reminder Theorem (CRT). The results indicate that the average of speed improvement is ~80% in key generation process, ~96% in decryption process, and only 4% in the encryption process.Â Â Â
