The Impact of Tax Amnesty on Tax Revenue and Tax Ratio: Case in Indonesia
Authors: Sari Diana , Mulyati Yati 
Published: April 2019

The development of tax evasion in a country, often the problem solving is done by voluntary disclosure or tax amnesty. Both voluntary disclosure or tax amnesty seem to be a dilemmatic policy between the desire to uphold the rule of law by prosecuting tax smugglers on the one hand by imposing tax amnesty on the other which is viewed from a legal point of view which negates these claims legally. Tax amnesty is a counterproductive action in the tax sanctions system that regulates the waiver of prosecution or reduces or eliminates claims against penalties or fines contained in the provisions of taxation legislation. The positive side of the tax amnesty program is an increase in state revenues from the tax sector. However, an increase in tax revenues is not always followed by an increase in tax ratio.Â Â

Published: April 2019

Soil stabilization using bio-grouting method based on microbial induced calcium carbonate precipitation (MICP) technology has been developed recently to improve the engineering properties of the soil. This new technology could provide an alternative to traditional methods of soil stabilization using soil-cement and chemical grouting. Vegetable waste is a good source for the growth of various kinds of microorganisms which is suitable to be applied as bio-grouting material. The bio-grout extract known as vege-grout was able to induce bio-cementation and bio-clogging process. In this study, vege-grout from vegetable waste was injected into the soil to strengthen the slope and improve the mechanical properties of the affected area. The changes in the subsurface soil after treatment with vege-grout were evaluated by electrical resistivity measurement. Resistivity test showed the resistance in the soil has increased after the grouting using vege-grout. Results indicated that the underneath soils have transformed from medium dense sand to dense sand. The water containment in the subsurface appeared to shift deeper into the ground. SEM analysis showed evidence of bio-clogging process as a result of microbial activities in the soil. This analysis showed that the vege-grout from vegetable waste has successfully strengthened and stabilized the slope from soil erosion.

Published: April 2019

Buffer overflow marks a phenomenon of a malicious technique employed by attackers, as reported in the NIST statistics. This paper presents a method of implementing a dual stack approach using software to protect the data stack from experiencing the attack by using 3 types of architecture, ranging from parallel program, multi-threading to a simple sequential subroutine.Â The current research on dual stack may require new hardware or a modified version of compiler which may complicate the implementation. These implementations spark some major issues in code backward compatibility with some changes in the language semantics especially in handling the movement of data to and from the dual stack. This paper discusses the implementation of Alternative Stack prototypes in 3 types of architecture and observation on its behavior during the performance and security test. The test has been benchmarked against the programs that are compiled with Microsoft Security Cookie. The Alternative Stack Architecture 3 prototype displayed a significant performance against the benchmarked programs whilst maintaining the confidentiality, integrity and availability of the programs.

Published: April 2019

The current changes in climate have marked significant impacts in our daily weather. The changes have affected the trend, pattern and magnitude of rainfall-runoff as compared to the events commonly experienced. Flood is one of the effects of weather and climate change. Floods can be classified as one of the most devastating natural hazards and is a major concern to the country as it causes damages to human lives, environment, agriculture, land and structures. Therefore, effective flood planning and mitigation measures should be carried out in order to reduce the effects of flooding. Flood hazard map is one of the non-structural mitigation measures that can be used for planning purposes. Flood can be directly estimated or derived from frequency analysis when long duration of stream flow records is available. However, in the case of limited or no stream flow data available, design storm are generally used to estimate design flood. Downstream of Bertam Catchment is an ungauged river station where no flow records are available. Based on this limitation, in this study, design storm was used to design the flood map. Info Works RS was used to develop the flood model and sensitivity analysis of the design storm was performed. Results obtained in this study presented the comparison of flow between 100-years Annual Recurrence Interval (ARI) at various storm durations of 0.25hr, 0.5hr, 1hr, 3hrs, 6hrs, 12hrs, 1 day, 2days and 3 days. The maximum flow is found to be at 6hrs storm duration at 1103.418m3/s. Besides river flow, comparison of water level at 100-year ARI of various storm durations was also conducted. Results obtained from this study found that 24hrs storm duration will produce the highest water level at 1034.753m. By comparing the flow and water level, the result from river flow produces the maximum at 6hrs storm duration while the result of water level gives the maximum at 24hrs storm duration. Since, water level is preferable in producing flood hazard mapping at 2-D view, therefore, the storm duration is chosen based on results of sensitivity storm duration on water level conducted. Comparison is then conducted between 24-hrs storm duration at various ARIs. It can be concluded that 100-years ARI will lead to the maximum value of 1034.910mÂ water level. Suitable storm duration and Annual Recurrence Interval (ARI) are to be determined in order to produce the best flood hazard map. In this study, it is found that 100-years ARI and 24hrs storm duration are the best combination, performed based on water level.

The quality of Klang river water is deteriorating dramatically since it is in urban places every day and become one of the major problems.Â Therefore, the Malaysian government had initiated one river cleaning project named River of Life (ROL) project. This project is for rehabilitating and restoring the Klang river. A series of river water treatment plant (RWTP)s have been operated in Klang river catchment since 2014. Six RWTPs station has been monitored up to eight stations until presents. Eight parameters consisting of physio-chemical types and biological types have been recorded. RWTP effluent discharges are targeted to achieve Malaysia Interim National Water Quality Standard (INWQS) under Class II B. Since previous RWTP performance only emphasized on local river pollutants and certain conditions, this paper will investigate the effectiveness of full-scale RWTP unit process for river condition. Water quality assessment are involved which are consist of effluent water quality monitoring and pollutant removal efficiency. Most of the major pollutants able to be reduced by more than 50% reduction. Although BOD and AN still not able to achieve standard range gazetted by INWQS Class IIB, there is an improvement of river water quality at Klang River by using IFAS technology adopted in the RWTP system.

Authors: Mahat Norhazilah binti , Binti Ali Norâ€™ashikin 
Published: April 2019

In today's world, the development of new technologies has transformed the way employees perform their tasks without the limit of time and place. Bring Your Own Device (BYOD) is a concept to enable employees to perform their tasks with the limitless infrastructure, which allows mobility and access to anyone, anywhere using their own devices. The growing trends of BYOD have many benefits including increased employeesâ€™ productivity, increased employee satisfaction, and reduced costs. Â Despite the benefits, companies are also facing challenges such as security, loss and stolen of device and data, as well as malware attacks. One of the reasons for these challenges is that the BYOD policy is still not established and enforced in the public sector. Failure to create BYOD policy will have a negative impact on the organisation. However, issues and benefits are only anecdotes and they are not empirically studied in the public sector.Â Therefore, this study aims to identify benefits and challenges in Malaysian Public Sectors (MPS). Through literature review, benefits and challenges were extracted to list out the construct by measuring the frequency of constructs appearing in the literature. For that purpose, the quantitative survey will be conducted.

Authors: Muthaiyah Gopinathan , Palanisamy Kumaran 
Published: April 2019

Biodiesel is one of the well-known renewable fuels that can be produced from organic oils and animal fats. Biodiesel fuel that meets ASTM D6751 fuel standards can replace diesel for reciprocating engine. On the other hand, biodiesel can also be considered for gas turbine application in power generation. Nevertheless, inferior properties of biodiesel such as high viscosity, density and surface tension results in inferior atomization and high emission which consequently hinders the fuel for gas turbine utilisation and generate higher emission pollutants. Therefore, this work focused on the evaluation of atomization characteristics of second generation biodiesel which is produced using microwave assisted post treatment scheme. The atomisation characteristics of second generation biodiesel was evaluated using air blast atomiser in terms of spray angle and spray length. Subsequently, numerical evaluation was performed to evaluate sauter mean diameter and droplet evaporation time of second generation biodiesel.Â The results show, atomization characteristics of second generation biodiesel has improved in terms of spray angle and spray length, sauter mean diameter and shorter evaporation time compared to biodiesel which is commonly referred to as first generation biodiesel and fossil diesel.

Published: April 2019

The significant increase in the effect of global warming has given more attention to consumers to protect and preserve the environment.Â This is evident as we see the purchasing trends of consumers moving towards environmentally friendly products. In Malaysia consumers consist of three main generations with varied purchasing behaviors. The aim of this study is to investigate the variables affecting Gen Y consumerâ€™s green purchasing behavior. Phase 1 being qualitative in nature, involved five focus group interview sessions and a pilot study, while phase 2, being quantitative, involved the distribution and collection of questionnaires to Gen Y consumers of green products. The independent variables that affect green purchasing behavior are environmental concerns, attitudes towards the environment and environmental knowledge. Awareness of environmental problems was found not to be the variable that affects Gen Y green purchasing behavior. The implications of this study are that it supports energy conservation and environmental preservation businesses to better understand the green market environment, its opportunities and potential, enables businesses to better market their products, create products with competitive advantages and encourage the consumerâ€™s green purchasing intentions. Subsequently, this study assists the government or policy makers to promote green purchasing behavior among the Malaysia population.

Published: April 2019

Multi-wavelength fiber laser based on Brillouin scattering in optical fiber has the potential of application in dense wavelength division multiplexing (DWDM) system. To enhance the performance of the fiber lasers, researchers proposed usages of erbium, or Raman amplification techniques. In an earlier work, it was reported that extracting residual Raman pump out of the laser cavity improves the performance of a multi-wavelength Raman fiber laser. In this paper, we proposed a setup utilizing the residual Raman pump to pump an erbium-doped fiber in multi-wavelength Brillouin-Raman fiber laser. Results show that the additional erbium-doped fiber is capable of amplifying the propagating Brillouin Stokes by more than 15-dB. This in turn helps in achieving lower stimulated Brillouin threshold and subsequently allow for higher number of Brillouin Stokes lines to be generated.Â Â Â

Published: April 2019

Reservoir inflow forecasting assists dam operator in reservoir operation by providing advance information on lake level. This paper discusses on the application of the physical-based numerical model to simulate one-dimensional channel network using WASH123D Model. The model was developed to simulate streamflow at two locations namely Sg Kejar and Sg Tiang, located in the Temengor catchment. The WASH123D model performed channel routing using shallow water equation. The model input data includes rainfall from 5 rainfall stations, river cross sections and simulated runoff data using SCS Method. Due to unavailable observed data, results comparisons were performed using streamflow results obtained using InfoWorks RS Platform. The peak flow from simulation results at Sg Kejar & Sg Tiang Station is 152.6m3/s and 36.6m3/s. The analysis shows good agreement for both simulations with Nash-Sutcliffe Efficiency of 0.68 for Sg Kejar and 0.99 for Sg Tiang. It is suggested that model recalibration shall be made once there is enough water level data to enable more accurate representation of spatial heterogeneity in the catchment processes.Â Â Â

Malaysian Nuclear Agency hosts the 1MW Thermal TRIGA MARK II research reactor since 1982. It first initial criticality was achieved on 28th June 1982 with loading of solid fuel elements like Uranium Zirconium Hydride. TRIGA MARK II started its operation of the research reactor on the same year with a 1MW power generation. Training, Research, Isotope Production and General Atomic (TRIGA) is designed to successfully actualize the variety fields of fundamental nuclear research, the manpower training and the production of radioisotopes. This study deals with the initial criticality analysis of the TRIGA research reactor using TRIGLAV reactor physics computer program. For this purpose, a model of its initial core will be developed and simulated using the software and the results will be validated against the experimental result as mentioned in the final safety analysis report (FSAR). The TRIGLAV computer code solves the neutron diffusion equation by using a finite differences method with iteration of fission density. TRIGLAV is based on four group time independent diffusion equation in two dimensional cylindrical (r, Î¸) geometry. Â TRIGLAV can also be applied for criticality of reactor, fuel burn-up calculations, and power distribution and flux distributions calculations of the core and also the reactivity predictions of the reactor.Â Â
