Distributed 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 occurs

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.

Hypertensive retinopathy is a type of eye disease where microvascular changes occur in the retina experienced by high blood pressure sufferers. The arterial and venous ratio (AVR) in the retina of the eye is an indicator used to determine the presence of high blood pressure, which is measured by the ratio of the width of the retinal arteries and veins. Traditionally, ophthalmologists use fundus images or retinal images of the eye to diagnose hypertensive retinopathy's physical symptoms and determine the phase of evolution. Still, traditional methods have limitations because, in the case of borderline stages, the early symptoms of hypertensive retinopathy will be difficult to identify manually, so they are often ignored. Referring to these problems, early diagnosis is needed for accurate prevention and treatment of hypertensive retinopathy. Based on the abovementioned issues, this service activity aims to implement a hypertensive retinopathy disease detection model using a local dataset from a regional general hospital in West Nusa Tenggara (NTB). It will compare the model detection results with those of three eye disease experts. Classification model testing results using the Messidor training and NTB Regional Hospital datasets. In models using the Messidor training dataset, the highest accuracy is a comparison with the results of the most senior expert's observations. The results of the classification model are only a tool to assist ophthalmologists in diagnosing hypertensive retinopathy, while the final decision remains with the expert or ophthalmologist.

Tropical diseases are common in tropical and subtropical regions and are often difficult to diagnose due to symptoms that resemble other conditions and limited access to healthcare facilities. This study aims to develop a self-diagnosis application that integrates the Certainty Factor and Dempster-Shafer methods to improve the accuracy and reliability of tropical disease diagnosis. The application is expected to assist the public in conducting preliminary diagnoses independently, enabling timely treatment and reducing mortality and morbidity rates. The novelty of this research lies in the integration of these two artificial intelligence methods, offering an innovative solution to enhance diagnostic capabilities. The system achieved an accuracy rate of 83% based on testing, with the Certainty Factor method addressing uncertainty in symptom inputs, while the Dempster-Shafer method complements its limitations by managing uncertainty more adaptively. This combination enables more comprehensive diagnostic recommendations. However, challenges remain in cases with limited symptom data, indicating the need for further development to enhance algorithm performance and expand the clinical database
