Comparative Analysis of Image Steganography using SLT, DCT and SLT-DCT Algorithm

Steganography is an interesting science to be studied and researched at this time, because steganography is the science of hiding messages on other digital media so that other parties are not aware of the existence of information in the digital media. Steganography is very effective in maintaining information security, because the existence of this information is obscured so that it is difficult to know where it is. This paper discusses hiding text into images using the Slantlet Transform (SLT) method, Descreate Cosine Transform (DCT) and Hybrid of SLT and DCT. The three methods are implemented in the frequency domain where steganographic imagery is transformed from the spatial domain to the frequency domain and the message bit is inserted into the cover image frequency component. The comparison parameters of these three techniques are based on MSE, PSNR, Capacity & Robustness. From the results of the tests that have been done, it is obtained that the highest PSNR value is generated using the SLT-DCT method, the largest storage capacity is the SLT method while the resistance, SLT-DCT method and DCT method are more resistant to attack than the SLT method

Uji coba atau scenario pengujian yang dilakukan adalah Ftp Deploy dan Web Server Nginx sehingga dapat menjaga ketersediaan dan sistem mampu melakukan failover saat terjadi kegagalan pada serverDistributed computing systems are one of the requirements in implementing server-based applications such as database servers and web servers in order to achieve high levels of performance. The problem that often occurs is failure on the server so that the performance of a server is disrupted, so it takes a deployment technique that can be used to provide a distributed system with high performance. Container-based virtualization is the choice for running distributed systems because of its lightweight architecture, fast performance and resource efficiency. One of the container-based virtualisations is the introduction of a distributed systems development tool called Kubernetes, which allows managing server deployments to provide high availability systems. The system development methodology used is the Network Development Life Cycle (NDLC). Of the 6 stages, only 3 stages are used, namely Analysis, Design, and Simulation Prototyping. The test or test scenario carried out is Ftp Deploy and Nginx Web Server so that it can maintain availability and the system is able to failover when a server failure occur

Optimization of The use of Wireless Lan Devices to Minimize Operational Costs

WLAN technology has been widely developed for the needs of internet access in people's lives. Several generations of WLAN technology include IEEE 802.11b, IEEE 802.11a, IEEE 802.11g and IEEE 802.11n. At the STAHN Rectorate Building, Gde Pudja Mataram, WLAN technology in its application requires financial consideration because excessive use of Internet Service Provider services results in a waste of operational costs. The application of WLAN is still not optimal, because there are not too many users, but the operational costs of implementing the local wireless network are very large, due to less optimal application of network infrastructure. The recommended WLAN technology is IEEE 802.11n, while the technology is the latest technology that has better quality than the previous generation technology. The research methodology uses the Network Development Life Cycle (NDLC). Of the 6 stages available, only 3 stages are used, namely Analysis, Design and Simulation of Prototyping. The results obtained from this study are models that design a WLAN that suits your needs, and complements the entire Building area.  Optimization has succeeded in reducing the need for ISP and client services while still being able to enjoy services as needed and cost optimization can be reduced by around 28%

Diharapkan dengan adanya aplikasi Linktree ini dapat memudahkan para pelaku UMKM dalam menjual produknya sehingga lebih dikenal oleh konsumen dan mendapatkan keuntungan yang lebih banyak

Home Security Voice Notification System With Arduino Sensor, PIR based SMS Gateway

The level of crime that afflicts households such as theft and robbery is still common. Many thefts occur when the homeowner is away and the house is staying for a long time. Although some residential neighborhoods already have security officers, human limitations can be a gap for perpetrators of theft. To overcome this, we need a guard who is always there to monitor the house to avoid theft. In this case the risk of guards on duty to guard the house is very large, such as acts of theft accompanied by violence. The design and manufacture of this system uses the Network Development Life Cycle (NDLC) method. NDLC is a method that relies on previous development processes such as business strategy planning, application development lifecycle, and data distribution analysis. There are 6 stages in the Network Development Life Cycle (NDLC) namely Analysis, Design, Simulation Prototyping, Implementation, Monitoring, Management. The purpose of this research is Designing a home security system that can guard the house in real time and can be accessed remotely. The conclusion of this research is that the entire system is proven to be able to work in detecting, giving warnings, and making calls to the user.Network Development Life Cycle (NDLC) namely Analysis, Design, Simulation Prototyping, Implementation, Monitoring, Management.
