The Internet itself is a form of utilization of a computer network system, a computer network system consisting of a group of computer systems and other computing hardware linked together through communication channels to facilitate communication and resource sharing among various users. TCP / IP is a standard protocol that is applied to the internet network. The existence of a router in a TCP/IP network is very important, this is due to the large number of hosts and the differences in the devices used on a TCP/IP network. Router is a computer network device that is used to forward data packets from one network to another, both within the scope of LAN and WAN networks (Yani A., 2008). As a result, a routing mechanism is needed that can integrate many users with a high degree of flexibility. Routing is generally divided into two categories, namely static routing and dynamic routing. Static routing is a routing mechanism that depends on the routing table with manual configuration while dynamic routing is a routing mechanism where the routing table exchange between routers on the network is carried out dynamically. Routing in the world of information technology (IT) is part of how to improve network performance. Routing is a process to choose the path (path) traversed by the packet. Routing itself is very instrumental in building a network, be it LAN or WAN. Currently the use of routing in a network is something that needs to be taken into account in a company. Today's companies that have business processes in the IT sector are very dependent on network availability. Network reliability is the main point in the operation of the system. An adequate and reliable network infrastructure is very much needed by the company, especially regarding the company's electability. Companies that have large-scale networks need several techniques so that the network can work optimally and reliably in overcoming various problems that arise, including network connectivity that is still not stable and link redundancy has not been implemented as a backup path to overcome network failures if interference occurs. alternative network paths that are used to increase network availability, so that if there is a broken link in a network, the data path can still be connected without affecting the connectivity of devices on the network </em></p> 2022-06-24T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) Implementation of Quality Improvements to Minimize Critical to Quality Variations in Polyurethane Liquid Injection Processes 2022-06-29T12:07:01+07:00 Nazaruddin Nazaruddin <p><em>PT Topjaya Antariksa Electronics is a manufacturing company that produces various refrigerators, home freezers, and showcase refrigerators.

Web Service is a set of standards and programming methods for sharing data between different software applications, distributing services over the internet that supports system interoperability. In this digital era, the system that will survive is one that can function on multiple platforms, and one of the options is to use web servicess. Data is exchanged in JSON format, and JSON Web Tokens are used for authentication security (JWT). The use of JWT for token-based authentication on web services can help overcome interoperability issues. JWT is stateless and allows for the inclusion of data in the token authorisation. JWT includes a number of algorithm possibilities, including HMAC. Overall, the adoption of HMAC outperforms the criteria of token generation time, token size, and token transfer speed. Storing JSON Web Token into local storage in the client browser using the HMAC algorithm has been presented in this paper. The proposed work has shown that JWTs do not need to be stored on the server but can be stored on the client browser side using local storage.</em></p> 2022-06-30T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) Web-Based Cooperation Information System at The Science Techno Park Technology Business Development Center 2022-07-07T18:56:26+07:00 Jefril Rahmadoni Ricky Akbar Ullya Mega Wahyuni <p><em>Science Techno Park (STP) Unand's partnership with various government, business, and legal institutions will continue for the foreseeable future in order to disseminate innovators' knowledge to the larger community.

Erpandi Dalimunthe <p>Utilization of the potential that exists in tourist attractions aims to increase the savings in expenses that must be borne by the community to manage tourism. The beach is a place that is rich and abundant in wind potential that can be used to drive wind turbines. To take advantage of the existing wind potential, of course, we must know how the wind potential is in the form of wind speed and locations that have wind speed potential and how to use it as energy to drive wind turbines. To obtain the potential of wind energy and utilize it, wind speed measurements are carried out using a digital anemometer and recorded for some time. The position of the measuring instrument installed must be protected from wind obstacles so that it is installed as high as 20 meters above the ground in an open position against the direction of the incoming wind. From the measurement results over a period of one day, the wind speed varies and changes at any time and the maximum value is 6 m/s during the day starting at 10:00 to 04:00. The wind speed profile obtained is analyzed and the type of turbine is determined according to the low wind speed below 10 m/s. From the analysis results, the appropriate turbine is the Savonius VAWT type and can produce electrical energy of approximately 2.43 Watts with a diameter of 0.11 m.
