Authors: Dwidienawati D , Abdinagoro S B , Gandasari D , Tjahjana D 
Published: April 2021

AbstractGeneration Z has started entering adulthood and the workplace in the last couple of years. Both generations Y and Z will be a major force in workplace as well as marketforce. Both generations shared similar characteristics, e.g. digital naïve, constant connection online, high confidence, and demanding. However, they are born and raised in different economic and life situation. Those differences will affect the beliefs, behaviors, and values. Understanding this will help companies and other organizations who work to tackle the environmental issue on how to approach and ensure their participation. At present, there remains limited studies to see the difference between both generations’ characteristics. This research aims to see whether there are differences in concern on the environmental issue between groups. A descriptive quantitative study was conducted in generation Y and Z in Indonesia. Samples were collected using snowball methods. Four-point Likert scale questionnaires were designed and distributed. 140 questionnaires were collected and eligible to be analyzed. The result shows there are no significant differences in the concern of the environment, participate in reducing plastic use, and the opinion of the importance of a company to have a sustainability development program. However, there is a significant difference in actively participating in an event promoting environmental issues. This research contributes to the body of evidence on Generation Y and Z characteristics.
Women’s representation and government welfare spending in Indonesia 1970—2020
Authors: Prihatini E S 
Published: April 2021

Abstract
Women’s participation in decision-making process is imperative in achieving Sustainable Development Goals (SGDs), as their representation will improve the quality of development in the society. Cross-national studies suggest that the number of women in parliament and in the labor-force are closely associated with higher government spending on education and health. Other studies highlight the correlation between women’s share in parliament with better economic performance measured by GDP per capita. Using a unique dataset for the years spanning from 1970 to 2020, this paper aims to unpack the experience in Indonesia, an emerging economy in Asia with a relatively stable democracy. The findings suggest that women’s presence in the national parliament correlates strongly positive with higher GDP. Also, with a weaker correlation, more women elected as legislator, bigger fiscal allocation by the government for education and health. On the other hand, the impact of women’s participation in the labor force has less significant connection with government welfare spending in Indonesia.

Published: April 2021

Abstract
As the world embraces the fourth industrial revolution, the relationship between customers and their clients will change. The rate of this change might vary from one organization to another; revenues from existing or new businesses that refuse to embrace this revolution will experience a steady decrease. Utility firms, whose operations are affected by this revolution, must devise a means of estimating the number of customers that will deflect from a grid. This article, therefore, presents a system dynamics (SD) model for utility firms’ revenue estimation. The model was used to study the relationship among the parameters that influence households’ connection and disconnection from a grid. A case study of households in South Africa was used to test the proposed model applicability. We observed that the model responses to change in internal and external parameters that affect utility firms’ revenue. When the administrative factor is 0.4, less number of households disconnect from the grid when it was compared with an administrative factor of 0.6. In addition, there was an increase of 12.04% in revenue when the administrative factor was changed from 0.4 to 0.6. Also, there was a 15.16% increase in revenue when the technological advancement factor was changed from 0.4 to 0.6. The model’s results show that it can be used to support a decision-making process in a utility firm.

Abstract
The demand for light weight metals in engineering design has led to the increasing use of aluminum and its alloys. However, conventional high-strength casting aluminum alloys usually exhibit low ductility and toughness, as a result of boundary segregation and coarse dendritic grains which result in its limited application in large-sized and complex shaped work pieces. Also, the possession of a significant low resistance to corrosion of Al 6063 alloys has been a major challenge in applications involving acidic and alkaline media. In this study, silver nano-particle was extracted from a fixer solution. Al 6063 was impregnated with silver Nano-particle at different percentage ratio to form a metal matrix nano composite and the Hardening heat treatment of the reinforced metal matrix nano composite was performed. The elemental composition of Al 6063 prepared from scrap was determined using Light Emission Polyvac Spectrometer. The hardness and microstructural analyses of the composites were evaluated. The micro hardness of the composites was positively influenced by the addition of AgNps and the hardening heat treatment process it was subjected to. The percentage increase in micro hardness of the sample not heat treated but impregnated with 3% and 9% weight nano particles are 20% and 22% respectively. Subjecting these samples to heat treatment further increased the micro hardness to 33% and 37% respectively. The morphology of the composites revealed reasonably homogenous distribution of the reinforcement in the matrix of Al 6063 alloy. It can be concluded that both percentage increase in weight fraction of AgNps and hardening has significantly increased the micro hardness and refined the grain morphology of the Al-AgNps composites.

Abstract
The generation of electric power is presently dominated by gas turbine (GT) power plants in Nigeria, as is the drift globally. This is due to gas turbine low carbon footprint, high power to weight ratio, and high efficient energy utilization in combined cycle configuration. The gas turbine operates off-design on leaving the manufacturer’s shelf. The information on gas turbine performance is relevant for the effective operation and maintenance of these plants. Design focus and performance off-design of the GE LM2500 turbine established in Cranfield University, UK, was undertaken to assess the effect of the imposed ambient situation on the GT routine factors such as power output, fuel flow, and mass flow. The results obtained indicate that the accessible GT power and efficiency are vastly penalized by an adverse ambient condition in addition to other factors relative to its design point. Such conditions are predominant in the tropics where Nigeria falls, with the obvious consequence that the user must give careful thought to site-specific operating conditions before the procurement.

Published: April 2021

Abstract
Using the most environmentally sustainable agro-waste fibers as reinforcement has opened up a new direction for polymer composite research. Research has recommended that altering of fibre surface by both chemical and physical means, increases the performance characteristic of natural fibre/polymer matrix. In this study, high-frequency microwave irradiation at a frequency of 2.45 GHZ and 550W power was used to treat natural fibre extracted from plantain (Musa paradisiacal) pseudo steam. Microwave modified and untreated plantain fibre was used to fabricate a biocomposite using polyester resin as polymer matrix, by means of hand lay-up and compression moulding technique. Results reveal an increase in mechanical strength of the modified fibre reinforced bio-composites at optimised conditions, thus creating opportunities and consistency to be use in technological and structural applications.

Abstract
The current study reports the effects of waste glass additives on the properties and compliance level of fired ceramic masonry bricks. In the course of producing durable bricks for masonry, waste glass powder sieved to 150 μm was added to clay, mixed with water and fired to 1000°C. The effects of the waste glass addition were investigated by subjecting 242 ceramic bricks produced to physical, mechanical, and thermal tests. Their morphological behaviour was thereafter examined. From the results obtained, the physical and mechanical properties were improved as waste glass content increased in the samples. Values of properties obtained were compared with existing standard values for bricks and it was observed that compliance level at 0% waste glass was 63%, at 10% waste glass addition, it was 75% and at 15% to 40% waste glass addition, compliance was 100%. Therefore, it was concluded that waste glass addition to bricks improved the properties of bricks for construction purpose.

Abstract
Computational models have been developed and solved by the use of a computer coded software Python on Spyder console. The models were developed to gain an improved insight of carbon dioxide capture process performance by concentrating on the volume flowrate of the flue gas. The models were based on chemical absorption method. The study was aimed at exploring the absorption capacity of monoethanolamine (MEA), chilled ammonia and potassium carbonate (K2CO3) systems by concentrating on the movement of flue gas volume. The profiling of volume was prepared in order to see how much of the flue gas will be lost at the end of absorption when the three mentioned absorbent are used to capture carbon dioxide (CO2). The results showed that high volume flow of the gaseous phase has led to poor absorption, whilst low volume flow yields higher CO2 absorption. Moreover, in comparison to K2CO3 and chilled ammonia, the MEA was found to have the best absorption capacity.

Abstract
An Operating System is an interface between a user and computer hardware. It’s a piece of software that handles hardware devices and acts as a bridge between an application software and hardware of the computer. Everything the user does is done in the user mode and what the system does is done in the kernel mode. The kernel is a computer program at the heart of the operating system, with absolute control of everything. Operating system concepts have been developed by many manufacturers over the years and a few quality ones to match with user demand and preferences. This paper helps compare operating systems by their quality attributes and using four of the most influential operating systems – Windows, Linux, Mac and Android OS, along with other technical details in assuring user guide when deciding what operating system to choose based on their requirements. The research uses factor analysis to obtain aggregate score based on selection criteria, with first choice at 50%, second choice at 42%, third choice at 6%, fourth choice at 2%. Windows 10 has highest GUI, Hardware Compatibility, Portability and Process Management features. Also it has high Memory Management, Text Mode Interface and file system features. However, Security feature on Windows 10 was least only 2% as fourth choice. Mac OS X has high percentage for Memory Management, GUI, Security and Architecture features. However, Hardware compatibility, Text Mode Interface, File System and Portability features was least only 2% as fourth choice. Linux Ubuntu 17.4 has highest Security, Text Mode Interface, Architecture and File System features. Also having high Portability and Process Management features. However, GUI and Memory Management was least only 2% as fourth choice. It was observed for latest version of operating system all have quality attributes but selecting most preferred choice of operating system would require proper analysis of the user. Windows with a percentage of 37% was first choice, followed by Linux having 33%, Mac with 23% and finally Android with the lowest score of 7%.
