Abstract

This study aims to determine: the practice of managing pension funds according to Islamic law and positive law, as well as the similarities and differences in the management of pension funds in Islamic law and positive law. This study uses the library research method, which means that the collection of data or materials needed in writing this thesis comes from books, scriptures, theses, journals and theses. The results of this study indicate that the practice of managing pension funds according to Islamic law is appropriate as long as the pension fund is not used as a deposit and the pension fund is immediately withdrawn, not stored in the banking system, worrying that the bank is still a conventional system. The practice of managing pension funds according to positive law: A pension fund is an income received every month by an employee who is no longer able to work, to finance his next living, so that he is not left stranded when he is powerless to find other income. Article 1 Point 4 of Law Number 11 of 1992, states that a financial institution pension fund is a pension fund established by a bank or life insurance company, to administer a defined contribution pension program for individuals. Similarities and differences in pension fund management in Islamic law and positive law. Pension fund management in Islam is based on a contract agreed upon by both parties and does not contain usury, maisir, tadlis, gharar and other elements prohibited in Islam, while in conventional it uses general management laws and does not involve both parties. initial agreement, so that there are fears of elements that are prohibited from transactions that are prohibited in Islam. The similarity is that they manage funds with the aim of providing benefits to retired customers when they are no longer working in government agencies.

Abstract

Maqashid al-syari'ah is al-ma'ani allati syuri'at laha al-ahkam (value content which is the purpose of law enforcement). Observing the three levels mentioned above, it can be said that for the level of daruriyyat, then in ushul fiqh it is categorized as amulet. At the hajiyyat level, it is categorized as rukhshah. Where as at the tahsiniyyat level, it is in the form of a complement which may contain elements of local customs (‘urf). The level of application of maqashid al-syari'ah in a legal provision is still based on the priority level which is considered standard. Unless it collides at the daruriyyat level, between maintaining religion at the first level and caring for the soul at the second level, then the form of solution can prioritize the safety of the soul. After the needs of dharuriyat and hajiyat are met, (by still prioritizing dharuriyat needs over hajiyat), then it is permissible to meet the needs of tahsiniyat, however, with the requirements, namely, if the primary and second needs are met without reducing the purpose of Allah and the servant.

Abstract

Nigeria faces the dual challenge of harmful industrial emissions contributing to climate change and unreliable power supply, demanding urgent attention. This study focuses on optimizing a grid-connected photovoltaic (PV) system at the Department of Electrical Engineering, Ahmadu Bello University Zaria, Kaduna, Nigeria, with the goal of achieving economic and environmental sustainability. The study utilizes HOMER, a widely used optimization tool for renewable energy systems, to design and evaluate three distinct energy scenarios. The first scenario relies solely on grid power, resulting in high annual costs of $2,838, significant environmental degradation, and zero renewable energy contribution. The second scenario integrates solar PV with grid power, reducing grid dependency but only partially addressing cost and environmental concerns, with an annual energy cost of $2,714 and 1,867 kWh generated from solar PV. The third scenario demonstrates the most favourable outcomes, combining high solar PV generation with economic benefits. The system produces 29,684 kWh annually, selling $521 worth of surplus energy back to the grid, resulting in a net yearly energy cost of $1,043. The initial installation cost is expected to be recovered within two years, offering potential savings of $20,000 over the system's 20-year lifespan. These findings show the viability of solar PV systems as a solution to Nigeria's energy challenges, underscoring the importance of balancing economic and environmental factors in energy system design. The study provides valuable insights for institutions and similar contexts looking to transition to more sustainable energy systems.

Abstract

The increasing use of renewable energy sources, such as solar and wind power, and the growing ubiquity of High Voltage Direct Current (HVDC) transmission systems to improve power transmission efficiency are the main factors behind the increased deployment of inverter circuits. However, high harmonic distortions in the resultant sine wave are a major problem for inverter circuits and could jeopardise circuit efficiency if left unchecked. This study presents a novel, affordable, and effective LC filter intended to remove almost all harmonic content from inverter circuits. The study uses PSIM software to model, design, and control a three-phase inverter. Starting with the DC power supply, the study makes use of effective three-legged IGBT (insulated gate bipolar transistor) semiconductor devices as switch elements due to their high and current rating as well as faster operation. The switching gate pulses that turn inverter switches on and off at regular 60-degree intervals are produced by the pulse controller that controls the switches. This study's results show that the innovative LC filter in the inverter significantly reduced total harmonic distortion (THD) in all phases of the power signal. Specifically, THD decreased from 37.68% to 0.47% in the red phase, from 37.69% to 0.48% in the blue phase, and from 37.71% to 0.48% in the yellow phase. This reduction results in a notable improvement in power quality in all phases of the signal. Additionally, there is a noticeable increase in voltage magnitude, stabilizing and raising levels from 17.92 V to 23.83 V in the red phase, 17.93 V to 23.81 V in the blue phase, and 17.83 V to 23.81 V in the yellow phase due to the LC filter. These results demonstrated the effectiveness of the LC filter-equipped inverter for industrial, HVDC, and renewable energy applications.
