Analisis Peluang dan Ancaman Produk Pasar Modal: Studi Kasus Sukuk di Indonesia

The last century, the world experienced 25 economy crises. Usury system claimed to be the main elements of the crisis. In this case, the financial institution; bank or non-conventional bank become main cast. One of them is the capital market which provides a considerable contribution to the cashflow for the economy of a country. So, non-usurious system is needed in order to minimizing the crisis. Islamic economic system through Islamic financial institution is considered to be the solution and alternative for the investors who have excess capital to be invested in non-usurious system. One of the instrument in Islamic capital market is sukuk, which is currently competing with conventional products. This research was qualitative descriptive research which aimed to analyze how the opportunities and threats of sukuk in Indonesia. Then, the instrument analysis was SWOT analysis. Based on the analysis it was found that overview of the implementation strategy of sukuk in Indonesia still had substantial opportunities. Stakeholders were expected to synergize and have a good commitment in the context of minimizing the weaknesses and the threats

Negative frequency-dependent selection is intensified at higher population densities in protist populations

This is the final version of the article. Available from the Royal Society via the DOI in this record.Natural populations of free-living protists often exhibit high-levels of intraspecific diversity, yet this is puzzling as classic evolutionary theory predicts dominance by genotypes with high fitness, particularly in large populations where selection is efficient. Here, we test whether negative frequency-dependent selection (NFDS) plays a role in the maintenance of diversity in the marine flagellate Oxyrrhis marina using competition experiments between multiple pairs of strains. We observed strain-specific responses to frequency and density, but an overall signature of NFDS that was intensified at higher population densities. Because our strains were not selected a priori on the basis of particular traits expected to exhibit NFDS, these data represent a relatively unbiased estimate of the role for NFDS in maintaining diversity in protist populations. These findings could help to explain how bloom-forming plankton, which periodically achieve exceptionally high population densities, maintain substantial intraspecific diversity.E.J.A.M. was supported by a NERC research studentship (NE/H025472/2) as part of the UK Ocean Acidification Research Programme

The Challenges and Prospects of Oil Companies Activities on Communities in Akwa Ibom State, Nigeria

The rising issues is what has happened to the impoverished communities in Eket Local Government Area whose livelihoods have been affected due to the activities of oil companies which is the backdrop of this work However Two communities were used namely Mkpanak and Upenekang of which ninety three copies of questionnaire were randomly distributed to each of the community in order to captured the impact of the oil companies activities such as type of infrastructural development impact on the environment nature of activities and companies by-products The data collected were analyzed using the Pearson s product moment correlation However Findings show that even though the oil companies in the area have contributed significantly to the socio-economic wellbeing of the people through income generation employment creation provision of social amenities their activities were not devoid of environment crises These crises arises due to oil spills which in turn affect the soil nutrients lost of aquatic life and mangroves Beside the data analyzed show a high positive relationship between the companies by-product and the impact on the environment which indicate that the oil companies have really destroyed the natural ecosystem which is the major source of sustenance to the impoverished communities Therefore the various stakeholders in environmental management must provide a mechanism that would guarantee the sustainability of the people in the ecosyste

Assessing the Potentials of Epoto Cave as an Ecotourism Asset in Abi Local Government Area of Cross River State, Nigeria

This research examined the potentials of Epoto Cave as an ecotourism asset in Abi Local Government Area of Cross River State. Three communities in Abi Local Government Area were used for this study. Three hundred and seven copies of questionnaire were randomly distributed to residents within the sample framework. The research findings shows that Epoto Cave has the potential for ecotourism development in the area. It was discovered that threat to local culture, exposure of community natural resources among others were community concerns towards the development of Epoto Cave for ecotourism. The data collected shows that some basic amenities such as effective road network, electricity and adequate security network in the area are needed to ensure the development of Epoto Cave. It was also noticed that the development of Epoto Cave can enhance community development as it would create investment opportunities, employment generation and at the same time lead to emergence of other small scale enterprises in the area. However, the neglect of the Epoto Cave for ecotourism development by government and private sector have caused increase in the rate of anthropogenic activities and socioeconomic activities that have degraded the entire aesthetics of Epoto Cave and its environs. Therefore, an effective mechanism must be put in place in order to ensure the development of Epoto Cave for ecotourism activities if the potential must be reaped.
