Abstract

ZSM-5 can be synthesized from Lampung Natural Zeolite (ZAL) and rice husks as a source of additional silica. To speed up the synthesis time, ZSM-5 was synthesized using microwaves. Based on this, the synthesis of ZSM-5 was carried out using microwaves at a temperature of 140 oC with a power of 540 watts with time variations of 10, 15 and 30 minutes with the seeding method as a template replacement of 20%. Amorphous silica with a SiO2 content of 95.324% was extracted from rice husks with a suitable alkali solution. The influence of synthesis time on the formation of ZSM-5 has been carried out. The resulting product was characterized using X-ray Diffraction (XRD), and FTIR (Fourier-Transform-Infrared), Scanning Electron Microscopy (SEM) and BET (Brunaur, Emmet and Teller). The results of the analysis show that the results of the research show that the synthesis of ZSM-5 has been successfully carried out by changing the amorphous phase from natural Lampung zeolite and rice husks into ZSM-5 crystals using microwaves which can shorten the synthesis time 216 - 72 times faster than with heating. conventional, produces high crystallinity, provides small particle sizes with larger surface area, pore volume and pore diameter, and microwave radiation does not damage the Si-O bonds. The best sample was obtained at a synthesis time of 30 minutes with a crystallinity percentage of 96.76% and a specific surface area of 138.616 m2 /g.

Abstract

Poverty is a phenomenon that occurs in almost every developing country. Poverty stems from the inability of some people to organize their lives at a level that is considered humane. The problem of poverty is an unresolved problem in almost every country, including Indonesia. The research method used in this study was a literature study by examining various literature related to the topics discussed. The purpose of this research is to analyze poverty in Indonesia. The results of the analysis show that poverty in Indonesia can be caused by declining standards of global per capita income development, declining work ethic and people's productivity, low levels of education, and limited capital, these conditions reduce the quality of human resources, which leads to decreased productivity. and income. The reason is that the problem of poverty remains a major problem that needs attention and concrete action through the implementation of programs that are both recovery, empowering and facilitative. Therefore, the author wants to analyze poverty in Indonesia along with overcoming economic problems in Indonesia.

Abstract

Sharia mutual funds are one of the halal investment options because they are in accordance with sharia provisions. In this sharia mutual fund, wakalah and mudharabah contracts are used. The contract between the investor and the investment manager uses a wakalah contract. Meanwhile, the contract between the investment manager and the investment user uses a mudharabah contract. This study aims to analyze the implementation of contracts in Reksadana Manulife Syariah Sektoral Amanah Kelas A. The research method used is a literature study by reviewing several journals and literature related to the topic of discussion. From the results of the analysis, it is shown that the Reksadana Manulife Syariah Sektoral Amanah Kelas A rights and obligations between investors as owners of capital and investment managers as users of capital are regulated using wakalah and mudharabah contracts. This sharia mutual fund complies with sharia provisions and is halal to be used as an investment. By looking at the development of sharia mutual funds in Indonesia, the author would like to analyze and provide deeper insight into the implementation of the contracts used in sharia mutual funds in Indonesia, especially in the Manulife Syariah Sektoral Amanah Kelas A Mutual Funds.
