Abstract

Zakat and waqf funds in the global scope are equivalent to 1% of the total GDP in the world. However, the usage of zakat and waqf funds is still not optimal. Blockchain could be used to supervise the management of the waqf and zakat. This study has a purpose for the topic development of previous studies related to the usage of blockchain for zakat and waqf management globally. This study used the bibliometric method to gather and analyze the secondary data. The data were collected from the Web of Science (SCI) website from 1979-2023. There were 415 metadata documents found and would be analyzed using R Studio software. The result showed that the majority of the total documents as in previous studies were article type. The co-authorship per paper was 23.13% from 415 documents. The affiliation countries of the authors with the biggest papers were Indonesia and Malaysia. They were also the two words that were most frequently used both in the abstract and in the title of the previous studies.

Abstract

Piping is a tool that functions to drain fluid from one place to another. The problem at Factory X is the failure of the boiler pipe. Pipe failures that occur are known by indications of leaks in the boiler. The initial process of a failure in an ordinary pipe is characterized by corrosion. The problem of corrosion in boilers is usually caused by feed water or feed water which still contains high oxygen levels. The purpose of the research is to determine the microstructure of the boiler pipe after experiencing the combustion process in the combustion chamber. This research method is an analysis of the chemical composition of boiler pipe material, Visual / Macro and Micro Testing. From the results of the inspection, observation, it can be concluded, the cause of pipe damage on the outside of the fire side caused by erosion corrosion is classified as very severe because it is beyond the optimum thickness of the pipe. Specimen A which is a material that has not received heat treatment has a microstructure, where the condition of the fearlite area is greater than specimen B with heat treatment.
