PT Adi Satria Abadi is a company engaged in tanning. The problem faced by the company is the presence of defective leather during the goat and sheep tanning production process. From these problems, the purpose of this study was to identify the level of product defects, analyze the factors that cause defects, and make recommendations for improvements to improve the quality of goat and sheep tanning products. Data processing in this study uses the SQC (Statistical Quality Control) and FMEA (Failure Mode and Effect Analysis) methods. Based on the identification results, it was found that there were 1,507 holes for holes, 1,066 for thick defects, 1,061 for louse defects, and 1,086 for size defects. The results of the SQC analysis still have uncontrolled data based on the control chart which is on size defects with a total of 1,086 defects, while for hollow defects, too thick defects, and tick defects are under control. The results of the FMEA analysis show that the order of completion with the first priority is spotting bugs with an RPN value of 36. The suggested improvements to the company are by directly selecting raw materials and supervising employees.

The development of information technology in various fields, one of which is in the field of queuing systems. That we know about the queuing system which is so tedious because of the long process of queuing. Therefore, the number of customer queues at several banks so that customers cannot relax to carry out transactions at the bank is a problem that is often encountered, as well as what happened at PT. BPR SARIBUMI Bank Godong Branch, which still uses a manual system. To overcome this problem, a queue display is used that uses text and voice displays and prints the queue serial number so that customers no longer need to queue conventionally.
With this queuing system, the queue counter clerk, cashier or teller will have no difficulty in determining the first person to be served in the queue. This is a solution, but the display of the queue display uses electronic equipment that performs a counter so that the possibility of damage to the device exists. In making this final project the author uses Microsoft Visual Basic 6.0 software and MySQL database.

Entering the era of globalization, the use of information technology in all areas of daily life cannot be avoided. There are at least two technologies that have developed rapidly in the last few years for the lives of millions of people, namely the internet and cell phones. By combining these two technologies, technology is created that makes it possible to access information that does not depend on the information source and location of access, namely WAP.
 Along with the development of the combination of the two technologies, several business owners began to use it. One of them is the Podomoro Notebook Store, which is located at SCC Plaza Simpang Lima, Fl. V No. 62 Semarang which is engaged in selling notebooks is trying to use it. There are several things that might encourage this application to be used, including in terms of notebook sales. The absence of an application regarding ordering goods online is also an obstacle for the shop.
The solution to solving the problem of this case is to create a wap-based information system for ordering goods. With the wap-based information system, it is hoped that it will help a little in terms of sales and this system can help to order goods online.

Data security is very important today, because the amount of big data is increasing day by day, forcing every sector to review its security system. The security of SIM and STNK documents is always associated with the authorities. This authority can be public or private. In this country, in the transportation sector, the security of driver's license and vehicle registration documents are given to two private company authorities. Among them are Presprint PI for SIM and High Tech Telesoft for STNK card. Its purpose is to prove the authenticity, availability, and confidentiality of the SIM or STNK holder. However, until now, the security of these documents is still facing obstacles, such as the presence of several individuals who have fake driver's licenses or fake STNKs. Sometimes with the involvement of a particular system manager, the time it takes for the applicant to get a driver's license or STNK card, data management must be secured by one authority. Faced with this situation, to ensure that only qualified people who have the appropriate driving training certificate and have the original driver's license can be allowed to drive the vehicle. System security is optimized through the use of blockchain technology, in data management transparently and without central authority.

Internet of Things (IoT) is a dynamic global network infrastructure with standard configuration capabilities and interoperable communication protocols where physical and virtual "things" have identities, physical attributes and virtual personalities and use smart interfaces, and are integrated into the network. Water is a source of life for humans and nutrients needed by humans. One of the essential daily needs of living things in this world that cannot be separated is water. The problem or obstacle that exists with the use of artesian water is that when the meter calculation (usage standard) is still using human labor, in other words there is a mobile officer at the end of every month, while in the middle of the month the officer returns to provide a payment account receipt. Not yet, if the officer has difficulty checking, they have to be behind the customer's house if the meter (standard of use) is located behind the house, and the place is not strategic. Then sometimes the recording is not accurate because it is not in accordance with the usage of the existing customer being metered. This gives the effect of a longer process, less accurate results, and makes the job more difficult and customers also feel worried that if the staff is not careful about recording water usage, the authors are inspired to design and make a tool to make it easier to record water usage with modern technology. namely the Artetis Water Billing Information System using Water Flow and IoT-based Sim900A in the Purwoyoso village area of Semarang where people can maintain and manage water more effectively and efficiently for human survival.
