Data Security and Privacy in Cloud Computing Platforms: A Comprehensive Review

/in /by

Cloud computing is the on-demand usage of computer resources through the internet, allowing us to relocate application software and databases. Its purpose is to deliver IT services that enable clients to benefit from the pay-per-use model’s substantial cost advantages and the ability to flexibly scale up or down without having to make significant investments in new hardware. On the other hand, the provider manages the data and services under this cloud architecture. Consequently, cloud clients have less control over their outsourced data and depend on cloud service providers to safeguard their data and infrastructure from both external and internal threats. In this study, we look at information security in cloud computing. It is the consideration of information on the cloud, considering security concerns. This article will go through data protection strategies utilized all around the globe to provide optimum data security by lowering risks and threats. Information accessibility is beneficial for various cloud applications, but it poses risks by exposing data to apps that already have security escape clauses. In addition, the presentation will outline information security highlights for Data in Transit and Data at Rest.

 

Theoretical Study of Determination the Energy Gap of Murrastanine-A Conjugated Metal Using Density Functional Theory (DFT)

/in /by

The research has been carried out to determine the energy gap of the compound murrastanine-a conjugated with period 4 metals. The calculation of the energy gap is carried out theoretically using computational methods with density functional theory (DFT) and the basis set 6-31G*/B3LYP through NWChem software. The results showed that all period 4 metal conjugations could reduce the energy gap of the murrastanine-a compound except for conjugation with gallium metal. The energy gap of the murrastanine-a compound decreased from 4.479 eV to 4.444 until 0.019 eV. The presence of conjugation with metals makes the energy gap of murrastanine-a diverse so that it can increase its potential use. CaM2, CuM2, and AsM5 complexes can be potential as high-temperature sensors. CrM6 and FeM2 complexes can be potential as solar cells. KM, CaM2, TiM4, ZnM2, GeM2, and AsM3 complexes can be potential as blue LED devices. Complex compounds resulting from the conjugation process with period 4 metals can be formed stably except for complexes with potassium and calcium metals which are characterized by the absence of charge distribution.

/in /by

The internet has the potential to transform banks and the financial sector dramatically. The advent of online banking is projected to impact the variety of financial services that banks offer. Service delivery techniques may evolve if banks utilize new technology to analyses profitability. Online banking has made banking more accessible and convenient for both banks and customers, but it also has its own set of hurdles and problems. Despite the benefits of online banking, banks continue to confront difficulties due to customers’ reluctance to utilize it. This research will focus on Bank XYZ, a pseudonym of a real Corporate Bank in Indonesia. In an effort to compete with other players who have online banking products, Bank XYZ must be able to recognize challenges and opportunities that impact their internet banking product, namely XGEB.

Bank XYZ has over 1400 customers, but only 830 utilize XGEB. Since early 2021, this statistic has not changed. It is undergoing a complete digitalization transformation to support its internet banking services in order to give a better customer experience while being more customer-centric. According to an interview with Bank XYZ employees that engage directly with customers regarding the internet banking service, it was determined that the bank’s customer experience has fallen short of optimum customer satisfaction. This research discovers a number of internal and external elements that contributed to this. Customers’ perceptions of XGEB’s utility and simplicity of use are influenced by its user interface design and absence of necessary functionality. External challenges include the threat of new entrants as well as competition among existing rivals.

After completing a business solutions analysis, this research concluded that to enhance XGEB usage, Bank XYZ should first identify existing and future customer demands, and then provide customized solutions in the manner the consumer expected. In addition, this study suggests that XYZ include mobile banking as an internet channel and that XYZ buy or acquire a digitally savvy local bank to improve Bank XYZ’s competitiveness.

Business Opportunity Analysis on Halal Vaccine in the Indonesian Market (Case Study of XYZ Biopharmaceutical Company in Jakarta)

/in /by

Vaccine hesitancy is defined by the World Health Organization (WHO) as a behavior influenced by several factors, including issues of confidence (do not trust vaccine or provider), complacency (do not perceive a need for a vaccine, do not value the vaccine), and convenience (do not perceive a need for a vaccine, do not value the vaccine) (access). Muslim consumers are becoming increasingly aware of halal medications in addition to food products. They’re starting to notice the negative consequences of product development, testing, and production, all of which may deviate from halal standards. As a result of this confusion, the general public is beginning to question the sources of their medicinal items.

Conservative Muslims may refuse vaccinations due to worries that some vaccines were obtained from the contents of pigs or porcine, which Muslims are prohibited from eating. Today, a quarter of the inhabitants of the world are Muslims. This figure is expected to grow by 35% over the next two decades, leaping from 1.6 billion to 2.2 billion by 2030. By 2021, the worldwide halal pharmaceutical industry will be worth USD 132 billion. Based on data from the Directorate General of Population and Civil Registration of the Ministry of Home Affairs, the total population of Indonesia is 272.23 million in June 2021. Of this number, 236.53 million people (86.88%) are Muslims.

To turn this hesitancy into an opportunity, XYZ Pharmaceutical plans to build a manufacturing plant for halal vaccines. In this research, the vaccines that will be produced by XYZ are ACYW135 Meningococcal Polysaccharide Vaccine, ACYW135 Meningococcal Conjugate Vaccine, 13 Valent Pneumococcal Polysaccharide Vaccine, and 23 Valent Pneumococcal Conjugate Vaccine. These vaccines are selected due to their close association with halal vaccines for the use case of Indonesian vaccine hesitancy. The objective of this study is to assess the feasibility of the halal vaccine manufacturing plant project through financial methods emphasizing capital budgeting technique, internal study, and market analysis. The result of this study shows that the development of the XYZ halal vaccine manufacturing plant is financially feasible due to the net present value of (USD 81,141,154), internal rate of return of (31.43%), the payback period of 4 years and six months, and the profitability index of (5.06), which in other scenarios testing are all acceptable for this project.

Backward Design on Online Teaching for Spanish Technical Engineering Students

/in /by

Pedagogical practices in Spain maintain a traditional format in which the teacher is revealed as the neural axis of the teaching-learning process, limiting the student to a passive role in which they merely reproduce the knowledge transferred without being able to contribute new knowledge through critical, reflective and transformative postures. Added to this reality is the fact that teachers are not up to date in the use of new information and communication technologies. The general objective of this research is to propose the application of the Backward Design Method in a technical engineering degree in a Spanish university in order to develop the understanding and transfer of what has been learned in the English language. This research was carried out with the purpose of proposing solutions to problems caused at the time of developing the class regarding the teaching-learning of the English language.

/in /by

The potential growth of video streaming market is derived by the growing revenue the high consumption towards entertainment in the market. This led to the intense competition in the OTT (Over-the-Top) industry, as OTT players focused their business with the subscription model that competed both for content and subscribers. Among the competitors, Vidio placed as the third rank based on the new paying subscribers in Southeast Asia. However, despite the growth of the new subscribers, the existence of weekly subscription still became a challenge to Vidio along with its impact that has tendency to result churn and unhealthy subscription cycle. To formulate strategies to enhance user retention, researcher use Consumer Decision Journey framework (McKinsey, 2009) to analyze the behaviour of the existing and ex-users of Vidio, and Customer Switching Behaviour (Keaveney, 1995) to identify the switching factors. This study conducts a quantitative method through online questionnaire and qualitative method through online interview. Those frameworks show alignment in identified the main factors of user willingness to keep subscribing and the switching factors which are content offerings, price, convenience, attractive interface and brand trustworthiness. This lead to the proposed solution based on the framework used, TOWS matrix and Diamond Strategy Model which focus on improving the competitive advantage of Vidio’s service quality including its content offerings which requires completeness, exclusiveness and attractiveness, as well as product development of feature improvement, personalized recommendation, resolution quality to improve user experience, also strengthening strategic partnership and company driven marketing to enhance the brand attractiveness that will reflect on the consumer-driven marketing while balancing the price offers with the benefit provided.  Lastly, implementing a new subscription pricing strategy by creating a special monthly subscription for high-demand content is needed to result in a healthier subscription lifecycle and to avoid churn users from weekly subscription.
