<![CDATA[Pondok Pesantren Qur'an Almajidiyah is an institution that is engaged in Islamic education. Every year, the Qur'an Al-Majidiyah Islamic Boarding School holds admissions and selection of new santri candidates and also accepts transfer students from other Islamic boarding schools. The prospective students' data is recapitulated into excel as a database and the data often has a mismatch with the original data during the value entry process resulting in a large amount of energy and energy expended so that the data collection process such as preparing the selection examination assessment forms is still taking a long time. From these problems, an application is needed that can help the process of admitting new students become easier. This final project presents an administrative application for admission of new students. This application is built using PHP (Hypertext Processor) as a programming language and MySQL as a database. This application is tested using black box testing which results in the system being successful according to its function. And testing uses the User Acceptence Test (UAT) and Usability Testing. Based on the User Acceptance Test (UAT), a total of 94% was obtained and Usability Testing was obtained for a total of 90.3%, which means that the administrative application for admission of new students has been accepted by prospective students, the PSB committee and treasurers of the Qur'an Al-Majidiyah Islamic Boarding School. With this application, it is able to make it easy for the Institute to collect data on prospective new students.]]>

<![CDATA[The kWh meter is a tool used to measure the total electrical energy consumed by equipment drawn from the main power supply in the house. People are currently using a lot of digital kWh meters with prepaid system payment methods. In the prepaid system, customers can charge electricity tokens with Stroom tokens that have been purchased through ATMs of a number of banks or at the nearest counters. This Stroom token will be entered through the keypad on the digital kWh meter. This digital kWh meter system is considered less than optimal at this time, in this industrial 4.0 era, many users have high enough mobility so they are not always in the home environment for every activity. To solve this problem, an application was created that can monitor the remaining digital kWh meter electricity tokens and can charge electricity tokens. The method used is an android-based application that uses MIT App Inventor as the application design, then the server used is PHP/HTML and a MySQL database to accommodate data that has been processed through the Raspberry Pi microcontroller 3. The results of research testing are very good on the registration page, login page. The test results on the stroom token input page from the keypad have a 27.42 second delay on the solenoid.]]>

<![CDATA[The lungs are part of one of the organs in a system, namely breathing which is useful as a container for the exchange of oxygen from the air which replaces carbon dioxide in the blood. Which is in the chest and also the most important organs in the human body. And covered by a double-wall sac or pleura that lies on the outer surface of the lung and is also protected by the collarbone. Humans have two parts of the lungs, namely the right side is divided into 3 parts and the left is divided into 2 parts. Homotopy comes from the Greek homos and topos, tomos has the same activity while topos has topology. Homotopy Tree is a method used to obtain an object boundary in an image based on the color equation between neighbors. The test results with manual segmentation use the ROC (Receiver Operating Characteristic) method. In testing the system several X-Ray images of the throax for the right lung and left lung will produce an average value of accuracy, sensitivity and specificity of the two parts of the lungs. In this final project using several samples of x-ray images of the chest, which will be calculated the validation results of the right and left lung organs. This application system can automatically calculate the accuracy, sensitivity and specificity of human lungs which can simplify medical work such as assisting radiology. The purpose of the application system for lung segmentation is to facilitate the measurement of thorax x-ray images to be more efficient than manual measurement. This system uses the preprocessing stage to improve image quality in order to obtain good results.]]>

<![CDATA[Caltex Riau Polytechnic Building has 3 floors which are always crowded with students, lecturers and staff every day. The network connection inside the building is not as good as the network connection outside the building because the signal from the BTS is attenuated by the thick walls of the building, causing the signal strength inside the building to be weak. The solution to overcome the problems that occur is to design an indoor Femtocell network on the LTE network in the building. Caltex Riau Polytechnic which can improve signal quality and expand coverage. This design applies the COST 231 Multiwall propagation model which will be simulated using RPS Software. Before designing the femtocell network, calculations are carried out based on Coverage and Capacity to get the required number of FAPs per floor. The simulation results get the average value of RSRP on each floor of the Main Building is -48.55 dBm, -48.81 dBm, -43.18 dBm and the average value of RSRP on each floor of the Multipurpose Building is -45.16 dBm, -51.16 dBm, -42.61 dBm.

<![CDATA[The intestine is part of the human digestive system which starts from the stomach to the anus which consists of two parts, namely the small intestine and the large intestine (colon). Many types of diseases and inflammation that occur in the large intestine are caused by many factors, where if the inflammation gets worse it can cause colon cancer. In the medical world, conventional disease detection is based on detection by taking blood tests or tissue samples using a microscope that can be seen visually with the human eye. Taking a test like this may result in errors that will affect the final diagnosis of the disease. So in the final project, a Computer Aided Diagnosis (CAD) system was made to be able to detect and classify the types of diseases in the large intestine from the colonoscopy image using the Adaptive Neuro Fuzzy Inference System (ANFIS) method quickly and accurately so as to ease the work of medical professionals.]]>

<![CDATA[Rapid technological development requires services that can be accessed at any time. The increasing number of client requests will result in the server being down due to more workloads. Therefore, clusters are present to handle increased server workloads and evenly divide each server. However, to run a cluster requires cluster orchestration software that is Kubernetes. Kubernetes is used for container management. The virtualization technology used in Kubernetes is Kernel-Based Virtual Machine (KVM) virtualization. In this research, we compare latency, CPU usage, and memory usage when opening web pages, between conventional technology and Kubernetes cluster. The results of the highest latency test are 16614 ms by Kubernetes cluster and the lowest latency is 1522 ms by conventional technology. In conventional systems, the response from the user is directly received by the web server, processed and then sent. In Kubernetes clusters, there are nodes running on top of virtual machines, so it takes longer to respond. Good latency is low latency because it can open web pages faster. In the standby state, the lowest CPU usage and memory usage occurred in conventional were 0.07% and 28% because there were no nodes running on the virtual machine. In a busy state, the lowest CPU usage occurs on the Kubernetes cluster server is 1.06% due to the division of workload on virtual machines. The lowest memory usage occurs on a conventional server is 57% because there are no nodes running on a virtual machine.]]>

<![CDATA[The development of the technology industry is currently very fast, not to mention that household electrical products are also increasingly varied. All of this equipment really requires electrical energy to operate it. Sometimes in a household there are a lot of electrical appliances, regardless of how much electricity is installed. Safety and comfort problems caused by overload currents are one of the most important things for electric power users. From the description above, the authors found an idea to make equipment that functions to monitor and control the use of electric power, namely a monitoring system and control of electronic devices based on android. The tool uses an ESP32 wifi module, ACS712 current sensor, 4 channel relay and an Android Smartphone. The way this tool works is the ESP32 wifi module measures the incoming current through the ACS712 sensor, after the current is obtained the ESP32 wifi module calculates the electricity usage rate (Tariff = (Power x electricity rate / watt) which is then stored to the server. If an electronic device crosses the power limit, then the electronic device is cut off via a relay on the last device. The server will be given a storage memory of the monitoring results in the form of a graph, so that it can be viewed again and given a scheduling system for the on or off time of each electronic device. On this tool, the accuracy level of the ACS712 current sensor is obtained , at sensor 1 is 98.56%, sensor 2 is 98.54% and sensor 3 is 98.33%.]]>
