Abstract

The hydroponic method of growing has developed rapidly in recent years because it can save agricultural land. Hydroponic planting systems need to pay more attention to the pH content of the water because water is the main factor for the growth of hydroponic plants. So far, hydroponic owners still use manual methods to monitor Ph levels in the water, measuring PH levels using a PH meter and then giving a solution to lower or increase PH levels according to the measurement results. This activity must be done regularly to maintain plant fertility. This research develops a solution in the form of a tool to control the PH level of the water automatically using the SKU SEN 0161 sensor. This sensor works by checking the PH level of the water. If the PH level of the water is too low (acidic), then the alkaline solution pump will turn on to increase the PH level of the water. If the PH level of the water is too high, then the acid solution pump will turn on to lower the PH level of the water. To get good measurement results, a PH sensor calibration process is carried out using a linear regression method by comparing the voltage data from the sensor with the water PH data measured using a PH Meter. From the results of testing the accuracy of the water PH sensor, it has good accuracy with an average error of 0.51%.

Abstract

Web-based Academic Information System (SIA) has been used by all students of the Faculty of Information Technology KH. A. Wahab Unwaha Jombang University. Because all student academic records are stored through the campus network, it is necessary to conduct research on security so that a secure system is obtained. This research was conducted with steps including analysis and testing of installed systems, analyzing needs, designing problem solutions, making repair modules, installing modules and retesting repair modules. From the results of the research conducted, it can be concluded that there are weaknesses in the login system. The weaknesses include the use of the Student Identification Number (NIM) as the default username and password, username and password data is not encrypted before being sent to the server over the network, traces of usernames and passwords left in the browser as a cache or in the password manager can be seen as unencrypted plaintext. From the security analysis results, the SIA login system can be improved by applying HMAC MD5 encryption technology and Challenge Handshake Authentication Protocol (CHAP). Challenge is generated by the server randomly and used as a key in the HMAC MD5 encryption process. With the use of challenge passwords sent in the form of hash values will always be different in each session. Javascript on the client side is used to perform encryption so that the data before being sent to the server is already in an encrypted state.
