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

Authors: Halim Helmi A , Hayder Gasim
Published: April 2019

This research is an acoustical performance study in an open cycle peaking gas turbine power plant located at the southern coast of Peninsula Malaysia. Referring to its location at the middle of residence and tourism area, throughout its operation years, several complains from public has been lodged about the excessive operational noise at the perimeter of the plant and statistically from the last decade, twenty-four (24) noise related public complains were recorded. This issue has initiated a study to determine the current operational noise level as well as the effectiveness of the existing noise barriers. Based on EIA approval, the boundary noise for the operation should be limited to 55 dB(A) at any time. The field measurement of noise level at two (2) different locations are assessed in-situ and continuously noise monitoring covering all the plantâ€™s operational regime and at different plant operational pattern. These results are compared with the initial noise report during its early year of operation in 1999. Finally the hypotheses then compared with the referenced legislations. Results from all the methodologies show the current operational noise level of the plant are within the permissible limit, however the overall operational noise of the plant is increasing compared with 1999 report due to the increasing of surrounding activities as well as deteriorating of current engineering and natural noise barrier arrangement. Mitigation plans has been recommended to the management to minimize the impact of the excessive noise to surrounding residence and to the plant workers. On top of that, the theoretical and commercial implication of the research is also discussed.

Tight glycaemic control in critically ill patients is used to reduce mortality in intensive care units. However, its usage is debatable in reducing hypoglycaemia or accurately maintain normoglycaemia level. This paper presents the assessment for two ‘wider’ Stochastic TARgeted (STAR) glycemic controllers, namely Controller A (blood glucose (BG) target 4.4-8.0 mmol/L) and Controller B (BG target 4.4-10.0 mmol/L) with 1 to 3 hour nursing interventions. These controllers were assessed to determine the better control on diabetic and non-diabetic patients. 66 diabetic and 66 non-diabetic critically ill patient’s data from Hospital Tunku Ampuan Afzan (HTAA) were employed for virtual trial simulations with a clinically validated physiological model. Performance metrics were assessed within the percentage time in band (TIB) of 4.4 to 8.0 mmol/L, 4.4 to 10.0 mmol/L, and 6.0 to 10.0 mmol/L. Controller A shows better performance in normoglycaemic TIB of 4.4 to 10.0 mmol/L where non-diabetic and diabetic patients achieved 92.5% and 83.8% respectively. In conclusion, Controller A is higher in efficiency and safer to be used for both patients cohorts. However, higher clinical interventions in diabetic patients within this control raise the alarm to reduce nursing workload. This is believed to improve clinical interventions burnout and ensure patient’s comfortability.

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.

Nowadays, sandblasting is commonly use in industries. The ability of sandblasting is to remove any stain, unwanted matter and many other functions making this process generally used worldwide. The effect of sandblasting on mechanical properties of ASTM A516 grade 70 was investigated in this study. Samples of the material have been sandblasted with different size of grits and times. Surface roughness, hardness and tensile was measured before and after sandblasting. The roughness test result showed that when the time duration of sandblasting increased, the roughness of the specimen also increased. Based on hardness test result, it showed that the hardness improved when the smallest size of grits was applied. However, the hardness decreased when the size of grits and time was increased. The tensile test result pattern showed quite similar to hardness test result. The size of grits and time duration for sandblasting need to set depending on application of the sandblasting process usage applied to the samples or materials.

Published: April 2019

The mechanical performance of silica modified epoxy at various concentration of sodium hydroxide for surface treatment of multi-axial kenaf has been analyzed. Epoxy resin with amine hardener was modified with silica powder at 20 phr and toughened by treated kenaf fiber that immerses in various concentrations of sodium hydroxide (NaOH) ranging from 0% to 9% of weight. The composite was analyzed through differential scanning calorimetry (DSC) to ensure complete curing process. The mechanical properties of the composites were analyzed through flexural test, Charpy impact test and DSC to ensure the complete curing process. DSC analysis results show epoxy sample was completely cured at above 73Â°C that verifies the curing temperature for preparation for the composite. Hence, 3% NaOH treated composite exhibits the best mechanical properties, with 10.6 kJ/m2 of impact strength, 54.1 MPa of flexural strength and 3.5 GPa of flexural modulus. It is due to the improvement of fiber-matrix compatibility. Analysis by SEM also revealed that a cleaner surface of kenaf fiber treated at 3% NaOH shown cleaner surface, thus, in turn, improve surface interaction between fiber and matrix of the composite. The composites produced in this work has high potential to be used in automotive and domestics appliances.

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.

Published: April 2019

The separate absorption, grading, charge, and multiplication (SAGCM) InGaAs/InP avalanche photodiodes (ADPs) are widely used in long distance, high bit rate optical communication system due to their high performance and response to optical fiber wavelength spectrum. In this work, the effect of multiplication layer width (MLW) and absorption layer width (ALW) on APD performance is studied and investigated. Silvaco TCAD software is used as simulation tools to simulate a precise model of InGaAs/InP APD and analyze its, performance under an illuminated condition. As such, three different ALW with various MLW has been simulated while the structure values and material parameters are kept constant. It was found that in the APD with smaller MLW, the distance between the punch-through voltage and the breakdown voltage can be maximized. Therefore, the operation region of APD will be extended. In addition, the multiplication gain is obtained from the photocurrent and primary current by taking the APD collection efficiency effect under the consideration.

Published: April 2019

Groundwater quality is one of water resource problem. This problem is driven by contaminant transport phenomena and can be described as a mathematical model. Contaminant transports equation usually is composed by advection and dispersion flux. In the porous medium or aquifer, contaminant meet tortuosity effect, therefore hydrodynamic dispersion must be considered as the development of dispersion flux. This paper explains the mathematical model of groundwater contaminant on fully saturated condition. It starts from governing equation of contaminant transport. Advection flux is based on groundwater velocity. In steady state condition, groundwater velocity can be determined as certain value. In another hand, in the transient condition, groundwater velocity must be determined based on the solution of groundwater flow model. Dispersion flux is calculated through first Fickâ€™s law and this component is distinguished into two parts follow mechanical dispersion and molecular diffusion. Mechanical dispersion affected by groundwater velocity and dispersivity. Contaminant transport equation is solved numerically using Finite Difference Method (FDM). This final model is validated theoretically and then this model is simulated into transient condition. The result of the simulation is described and explained graphically. Based on this research, the result of FDM model has similar physical behavior to FEM model from CTRAN example.

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.

Recently, bauxite waste was found as newly sourced of Fe-based oxygen carrier in chemical looping combustion (CLC) since it contains high Fe and capable to be used as oxygen carrier at low cost. This study focuses on synthesizing and characterizing the bauxite waste that found in Malaysia with Mn2O3 using dry impregnation method and study the feasibility of this bauxite waste as oxygen carrier. Results show the combination of bauxite waste â€“ Mn2O3 at 900Â°C produces crystallite size 21 nm with the presence of Fe-Mn, stable Al2O3 and Ti elements that can improve the reactivity of Fe-Mn oxygen carrier. Moreover, Al2O3 that contains naturally in bauxite waste can acts as supported material for Fe-Mn oxygen carrier in order to increase performance in CLC process. Therefore, this powder was successfully synthesized using dry impregnation method at calcination temperature 900Â°C and fit to be tested in a fluidized bed reactor to simulate the CLC process since it has smaller and stable particle size.

Automation in Civil Engineering design is no longer unfamiliar anymore in the construction industry. It brings great efficiency gains and has reduced many of the complicated aspects of design. Automation has been developing since over the last four decades where advancement of computer hardware and in line with software developments has enabled various sort of design to be computerized. The design process is now more fast and accurate, and the entire process has been outstandingly improved by the available technology. However, the problems related to computerized design, started from the possibilities for unrecognized or unanticipated consequences as the design becomes more complicated. In line with it is the global warming issue that has been threatening the human being. Therefore, this paper reviews the design automation and its application in civil engineering design emphasizing in assessing the energy efficiency of buildings, which includes background information, its application, advantages, and challenges and also suggestions to further improve the automation in civil engineering design by artificial intelligence (AI). It was discovered that since over the past few years, BIM implementation in Civil Engineering design has started to be adopted massively in construction industry due to its tremendous advantages. In this paper, a new flow process in design automation in assessing building sustainability has been proposed by implementing AI BIM which is linked with MyCREST, a green rating tool in Malaysia in order to assist designers to conceptually design for a more energy efficient building.

This paper describes CFD investigation of flow and heat transfer in liquid cool plate of a lithium-ion battery. The work aims to compare the cooling performance of an LCP at different fin arrangement for both laminar and turbulence conditions. Prior to the extensive simulation works, the prediction of surface and liquid temperature is first compared made by conducting an experiment using one of the fin arrangement. Good agreement was obtained indicating the ability of the current model to simulate the flow and heat transfer of similar domain at different fin arrangement. The results indicated that the behaviour of the flow and heat transfer is different at laminar and turbulence conditions. The louvered find arrangement showed superior performance in terms of the enhancement of heat transfer. A combination of optimum configurations for fin arrangement and flow condition has enabled excellence overall heat transfer performance of the system.

Published: April 2019

Separation of job functions between developers and testers due to enforcement of Software Quality Assurance (SQA) concept in software development has created worldwide demands for highly skillful software testers. This job function separation is to ensure that the systems or applications being developed are transparent at its testing activities. This will eventually lead to better quality of software products that will minimize impact or issues regarding software or system errors, bugs or faults. The aim of this article is to discuss on the current nature of software testing industry for identification of competencies issues or challenges related to software testers. This paper is intended to propose a software testing competency development framework as a job profiling, competencies assessment, training needs and professional career development for software testers. It is targeted that the proposed competency development framework will benefit software tester as individual, public or private agencies as organizations and education institutions as academia. Â
Initial Development of a Master-Slave Controller for a Five-Fingered Robotic Hand Design by Using Pressure Sensors Comparator Technique
Authors: Bahrin Syed Zainal Abidin Syed Kamarul , Sahari Khairul Salleh Mohamed
Published: April 2019

There are numerous robotic hand designs but the five-fingered robotic hand design is the most dexterous robotic hand design due to its similar appearance and motions with the human hands. The five-fingered robotic hands are commonly controlled or governed through a master-slave system that can be accomplished by using simple preset motions or other complicated and advanced technologies. However, a five-fingered robotics hand can also be controlled by a novel approach known as pressure sensors comparator technique. This technique compares the values from the pressure sensors that are strategically located at the glove (master) and robotic hand (slave). If the values differ, the actuators will generate motions accordingly. The initial finding based on the master and slave prototypes showed that applying this technique is very challenging due to the humans' physiological diversity. Nevertheless, a solution was proposed for further studies and future developments by introducing an offset.

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.
