The existing crowdfunding platforms still operate using centralized system. While centralized system can operate well, it requires a third party intermediary in order to operate and thus does not completely provide data security and transparency of crowdfunding activities. In addition, the existence of a third party intermediary in a crowdfunding activity also causes the existing processing costs to be expensive. Therefore, the crowdfunding system needs to be built in a decentralized manner so that it eliminates the need for third parties as intermediaries in the crowdfunding process. This study proposes a prototype of decentralized crowdfunding system using Ethereum blockchain and smart contract technology. The result of system functionality test using black box testing method shows that all functionality of the crowdfunding system can run properly while operate in decentralized architecture.

Blockchain which includes smart contract and tokenization features is the latest technology in the world, especially Indonesia. Smart contracts and tokenization make it very easy for users and can maintain valid data security, but there are still many universities that have not implemented the system so they have to involve many parties and costs. The problem taken in this study is the payment process for transactions such as credit and data processing that is vulnerable to illegal data leakage. This study aims to develop a smart contract system and blockchain tokenization in universities in the payment transaction process. The method used in this research is literature review analysis and testing method. The implementation of smart contracts and tokenization can replace third parties as security guards of transaction data with all Blockchain users paying attention and ensuring the integrity of the entire process and activity. This of course can avoid problems that arise from the presence of third parties in the transaction process. So it can be concluded that the implementation of smart contracts and Blockchain tokenization in payment transactions is the right solution to be applied in the payment transaction process at universities.

In this employee payroll application, if there is an error program there will be a loss for employees and the company. Losses for employees, if this application program error occurs then the salary reduction will experience delays due to the difficulty in the process of calculating employee salaries and employees will be late in receiving salaries. Losses for the company, if there is an error program in this application, the company will suffer losses if the employee wants a salary reduction quickly but the company cannot calculate quickly and accurately. In solving this problem, the authors use the black box testing method. Black box testing method is a test that sees the results of execution through test data and ensures the function of the software. Black box testing method has several testing techniques, namely Sample Testing, Boundary Value Analysis, Equivalence Partitions and others. From the testing techniques that have been mentioned, we use the Equivalence Partitions testing technique. Equivalence Partitions are tests that refer to data entry on the employee payroll application form, input will be tested and then put together based on the test function, both valid and invalid values. The expected results of this test are a payroll system for employees who are computerized, have standard rules in the process of developing the program so that it is easy to develop and maintain, and can minimize errors in processing salary calculations for employees.

The development of the internet and the implementation of technology that makes it easier for users to increasingly influence the business sector. Business people are starting to take advantage of the internet and technology to run their business or so-called E-Commerce. Denia Donuts Shop is an online shop that sells donuts in South Sumatera. The problems that occur, even though this store has marketed its products online, shop owners still use social media only in the process of transactions with consumers. This becomes very difficult when consumers want to make a purchase, consumers must send messages according to the format determined by the shop's owner, this method is made very difficult for consumers every time they make a purchase. On the other hand, the shop owner also finds it difficult to find product information, stock information, find out which consumers have bought during a certain period, and sales reports that are still recorded in a book. This article aims to build E-Commerce at Denia Donuts Shop that can help in marketing products widely and facilitate the process of transactions carried out by consumers. The system development method used is the prototype method. This research has resulted in an E-Commerce system that has been tested using the black box testing method and has been implemented in accordance with user requirements specifications.

A driving simulator gives a driver the impression that he is driving a real vehicle. This is done by simulating a realistic terrain and background scenario, as well as the windows, mirrors, sound, motion and vehicle dynamics of a real vehicle. A vehicle dynamics model uses the driver input such as accelerator, brake and steering position as well as terrain input to determine the position, orientation and velocity of the vehicle. Proper testing is necessary to ensure that the vehicle dynamics model represents the dynamics of a real vehicle. This implies more than only verifying standard vehicle dynamics equations. Integration and other numerical methods used may also influence the end result. Detail about the vehicle dynamics model used is not always available when developed by another institution. This article describes a "black box" testing method for verification of the vehicle dynamics model. This testing scenario has not yet been discussed within the literature.

Software that contains defects (errors) can cause harm. Losses caused can affect all stakeholders. Losses can take the form of financial, time, and others. So before the software is implemented it needs to be tested. Testing on an application aims to check whether a program is running properly or not. In testing this software will use Blackbox Testing. Black Box Testing Method consists of several techniques, including Equivalence Partitions, Boundary Value Analysis, Sample Testing, and so on. Among the many testing techniques, in this study the testing technique was chosen using Equivalence Partitions. Equivalence Partitions technique is a test based on data input on each form in the performance data information application system, each menu input will be tested and grouped according to function whether it is valid or invalid. Testing is done on 4 forms that will be filled with data form added jobdesk, form added work targets, form edit work targets, form approve work targets, and employee performance while in the company. The test results show that there are still many shortcomings when validating data to be entered, so that it can cause data stored in the database to be incompatible with the expected data. The results of this test can be used as input to improve the application of performance data for the future.
