Home security system is a term to describe a system of protection for residents in the environment and its surroundings from the interference of crime. A house has been equipped with high technology and can be connected to the security equipment in the house. Home security is made in order to create security, comfort and safety for residents of the house and can maintain the security of the environment without monitoring. Home security can be operated via a microcontroller and a mobile device. Home security in Indonesia is currently classified as very important, this is because the crime rate is increasing every year. The development of home security has been carried out using various existing technologies, such as the nodemcu microcontroller, which is a hardware platform intended to create prototypes of interactive electronic equipment based on flexible and easy-to-use hardware and software.
This research was conducted to produce a simple home security system by utilizing nodemcu technology and a combination of sensors and an ESP32 cam as a medium to be able to run sensors and home security cameras. This research was conducted by conducting a literature study, exploring the technologies used, as well as the concept of mobile-based software development. The next step is to define requirements, analysis, design, and implementation (programming and testing the system that has been built).

In recent years IoT has developed very rapidly. IoT devices are used to monitor and control physical objects to transform the physical world into intelligent spaces with computing and communication capabilities. Compared to cloud computing, fog computing is used to support latency-sensitive applications at the edge of the network which allows client requests to be processed faster. This study aims to propose a monitoring framework for containerized black box microservices in a fog computing environment to evaluate CPU overhead, as well as to determine the operating status, service characteristics, and dependencies of each container.
This study proposes a monitoring framework to integrate computing resource usage and run-time information from service interactions using a black box approach that seeks to integrate service-level information and computing resource information into the same framework. The proposed framework is limited to observing information monitoring after the server receives a request. This study uses JMeter to simulate user actions, which send requests to the server, and this research assumes the user knows the IP address of the server. For container monitoring methods in fog computing, all are indirect monitoring methods.
The results of this study indicate that the proposed framework can provide operational data for visualization that can help system administrators evaluate the status of running containers using a black box approach. System administrators do not need to understand and modify target microservices to gather service characteristics from containerized microservices. Regarding future research, it is suggested to expand the exploration of modified system information, and that part of the container management tool code can be pre-tried so that the framework proposed in this study can provide real-time quantitative indexes for the load balancing algorithm to help optimize the load balancing algorithm.

According to the research design, the research results go through two testing or validation processes, namely design validation by experts in this case expert lecturers in the computer field, and product validation by users.Validation is carried out using an assessment instrument in the form of a questionnaire or validation sheet. The questionnaire contains 10 questions that must be filled in with a value between 1 and 4. The total score will get a score of not good, enough, good, or very good. The final conclusion is a statement that the product must be replaced, can be used with many revisions, can be used with few revisions, or can be used without revision.The results of the design validation test by experts gave a total score of 37, included in the score indicator 31 n 40, namely "Very Good". The conclusion drawn by the expert for system design is "Can be Used Without Revision".The results of product validation testing by users give an average value of 35 so that it is in the indicator category and gets the "Very Good" predicate. The final conclusion of user validation is a product or prototype "Can Be Used Without Revision".This research was conducted in a restaurant, Restaurant isn’t just a place to eat something but also  a place to relaxing, meet someone or hang out with friends or colagues. Service of the restaurant is the main factor to make customer feel comfortable and relax. Many restaurant make their own order  and payment system   for  better service but they  forgot about  the speed of their services.Using research methods data collection, observation, and  interviewin Kedai Cangkir Gubug,  face to face service like greeting, take order, and serving order  all of it   is waiter’s  job.   All of that tasks need time at most that makes if the restaurant    have many customers, every single customer have to wait for  a longer time waiting for waiter that serving another customer. The payment method is quite troublesome for customer because they have to save order paper for payment in cashier later.The solution that writer’s made is to decrease the task of waiter so that services can be done equally with QRcode technology for ordering menu with the scanner is android smartphone. Payment only need name of customer or table number and customer can do it in cashier or they can request the bill at their table. Therefore waiter no need to take order one after another and customer can do payment easier.
