DECISION SUPPORT SYSTEM USING THE COMPOSITE PERFORMANCE INDEX (CPI) FOR WIRELESS REPEATER SELECTION

To connect to the internet, a device must have an internet connection via an internet network, one of which is through a wireless network or what is called Wireless Fidelity (Wi-Fi). On a Wi-Fi network there is a Wi-Fi router that is used to provide a connection to the internet network, but the signal from the WI-FI router is limited. Then the Wi-Fi signal needs to be strengthened with a signal booster known as a Wi-Fi Repeater or Wi-Fi Extender. Wi-Fi Repeaters are important devices for individuals, agencies and companies so that the desired areas get internet connection. So, to make a purchase of this product, foresight is needed so that the device chosen is right and in accordance with the needs. The large selection of Wi-Fi Repeater products on the market results in a person having to find information in advance regarding the specifications of the Wi-Fi Repeater product to be purchased. This has an impact on the length of the process in making decisions. The purpose of this research is to implement the Composite Performance Index (CPI) method on a decision support system for choosing Wi-Fi Repeaters, so that it can make it easier for users to determine alternatives quickly and precisely. The CPI method is used to solve decision problems with a number of alternatives through a combined index to rank alternatives from several criteria. The results of the calculations in the case study produced the highest combined index value, namely the Asus N300 Range Extender (A2) getting a score of 125, then followed by Mercusys WiFi Extender (A1) getting a score of 92.5, Comfast WiFi Extender (A3) getting a score of 100 and Xiaomi Mi AC1200 (A4) get a value of 100. The calculation results of the CPI method obtained by the system obtain the same value as manual calculations, so the developed system is declared valid. In addition, based on tests using black-box testing, it shows that the system built can function as it should.
DEVELOPMENT OF INFORMATION SYSTEMS FOR SERVICE AND CUSTOMER COMPLAINTS USING THE EXTREME PROGRAMMING METHOD

The Regional Drinking Water Company (abbreviated as PDAM in Indonesian) Tirta Yapono strives to provide the best service for its customers by providing access to information and complaints for the general public. However, currently the provision of information about company programs uses the company's web portal. This is considered insufficient, because the web portal is static or only provides information without interaction with its users. Apart from that, for public complaints, only provide telephone numbers and email complaints. This system causes slow handling of complaints due to the accumulation of incoming complaints via telephone or email. For this reason, a website-based system is needed that can provide services to the community dynamically and the public can submit complaints directly and can communicate with related officers through the website. This study aims to develop a website-based customer service and complaint system using the Extreme Programming (XP) system development method, so that users can interact directly so that information and resolution of complaints can be handled immediately. The XP method is a method for developing an agile development system that is capable of producing a short system and is proven by short development results. The developed customer service and complaint information system can manage new installations, customer complaints, announcements and customer chats. The resulting application is in the good category, because based on usability testing it shows an average value of 90% in the good category, so the application is feasible to use and as needed.

We show that it is decidable whether the language generated by a given context-free grammar over a tree alphabet is a tree language.Furthermore, if the answer to this question is "yes", then we can even effectively construct a regular tree grammar which generates that tree language.
Estimation of the Daily Maximum Air Temperature for Baghdad City Using Multiple Linear Regression

In this paper, we relied on historical observations for the period between (2005-2020) for the Baghdad meteorological station, which is characterized by a hot, dry climate in summer and cold and rainy in winter, as it is an example of a subtropical region. The multiple linear regression equation was developed and improved to produce a formula that predicts maximum air temperature. This was done by relying on climatic elements, namely minimum air temperature, wind speed, and relative humidity, and entering them into the formula as independent inputs that have a direct impact on estimating the maximum air temperature also calculating the correlation coefficients for each of them. The bias of the model was calculated and its value was entered as the correction for errors that accompany the application of the model.

Monitoring System and Hydroponic Plant Automation Using Microcontroller Internet of Things Based (IoT)

Hydroponics is a technique of cultivating plants without using soil media, but using water as a planting medium. Important factors that must be considered in hydroponic plants are plant nutrition, water, temperature, and light intensity. These factors are necessary for hydroponic plants for the growth and reproduction of hydroponic plants. Due to the nutritional needs of hydroponic plants, farmers must take the time to check the concentration of nutrients in hydroponic plants so that the plants can grow well. Therefore, it is necessary to develop new methods of hydroponic farming so that they can grow and develop properly, which can be controlled and monitored automatically. Thus, farmers no longer need to come to agricultural locations. One of the technologies used is technology with the Internet of Things (IoT). This study uses a prototype methodology. For the plant sample used is the lettuce plant. The microcontroller is used as the main controller of all IoT components while the sensors used are the TDS sensor, temperature sensor and light intensity sensor. The research that has been done is IoT technology on hydroponic plants that can monitor and automate plant nutrition settings that are personalized to the needs of hydroponic plants. From the results of testing the IoT tool by reading data from the light intensity and temperature sensors, there is a link between the UV light intensity produced and the water temperature in the hydroponic plant reservoir, that is, the higher the UV light intensity, the higher the water temperature and vice versa. In addition, the other factors are weather and climate conditions around hydroponic plants. IoT data is stored in cloud storage which requires a rental fee.

IMPLEMENTASI AUDIO STEGANOGRAFI MENGGUNAKAN ALGORITMA DISCRETE COSINE TRANSFORM

The data exchange is increasingly felt in the era of massive technological developments. This condition results in data requiring a safe path in the delivery process. However, the current condition of the communication system or public internet is not completely secure because there is a possibility of data interception and manipulation by eavesdroppers. One solution to this problem is to apply steganography. Steganography is the science of hiding messages into other media so that people other than the sender and recipient do not know the existence of the message. In this study, the implementation of the steganography method was carried out by hiding text messages in audio files. Audio files are used in this study with the aim of exploiting gaps in human hearing so that the difference between the initial audio and the audio that has been inserted with the message is blurred. The audio type used is wav, because the wav file contains uncompressed audio, so the file will not be damaged after the message is inserted. The use of the Discrete Cosine Transform (DCT) method was chosen because of its ability to maintain the integrity of the messenger file which resulted in the message being difficult to detect in the steganographic file. Implementation is done using Matlab. The test is carried out using the black box testing method and calculating the Peak Signal to Noise Ratio (PSNR) value using a combination of 8 audio files and 3 sound recordings of various sizes with the message inserted in the form of 6 sample messages of type txt and messages typed directly on the form provided. The results of the black box test show that every feature and button installed in the application can function properly. While the results of the message insertion experiment with a total of 88 test scenarios obtained 7 error scenarios and 81 successes. The error occurs because the size of the inserted data is larger than the duration of the audio to be inserted. PSNR calculation results show that 75.31% of audio files after message insertion have PSNR values above 40dB from a total of 81 successful trials. This shows that the output audio file that has been inserted with a message still has good quality.
