In life, in nature there is potential energy that can be utilized for human life behind the ineffectiveness of fossil energy for the environment, the use of natural resources that can be renewed by utilizing the energy contained in the heat of the sun. Utilization of solar thermal energy can be converted into useful power by using solar power plants (PLTS), therefore solar power plants are very potential to be developed in Indonesia, because Indonesia's climate is suitable as a tropical country with sunshine throughout the year. Solar Power Generation (PLTS) is a relatively new method of generating electrical energy by utilizing solar energy. The Solar Power Generation System (PLTS) as a power plant is directed so that it can be utilized by users who are not reached by PLN. The author conducted a study which was conducted to find out how potential solar thermal energy is to be used as a solar power plant, the use of natural resources is carried out in order to find out how potential the use of PLTS is. The process of generating solar power can be done with sunlight in order to produce electrical energy and be used for home lighting systems. One unit of lighting with 10 Watt specifications requires 132Wh. In solar panels there will be power loss depending on the type and quality of the solar panels, to stabilize the need for electricity consumption to be no less than the safe requirement, the total power per day is multiplied by 0.13 = 13%. This value must be generated by the solar panel

Blood Bank Refrigerator is a piece of equipment used as a cooler. It is usually used to store blood, and various blood products such as plasma, platelets, and red blood cells. Blood Bank Refrigerator can maintain the quality of blood products even if stored for a long time. Inappropriate temperatures can make blood clot or rupture, making it unsafe to give to patients. The problem with the blood bank referigator is that it cannot be monitored, and currently monitoring the temperature in the blood storage refrigerator is still done independently by taking manual notes.Based on the description above, in this Final Project the author will make a database-based blood bank referigator temperature monitoring tool. This research uses the System Development Life Cycle (SDLC) method, which is the process of making and changing systems as well as models and methodologies used to develop a system. The temperature measurement is done with a value of 4 ° C which is displayed on the LCD and database. Using an average time of 12 minutes and measurements every 2 minutes testing 6 times from 2 blood bank refrgator obtained an average difference of less than 0.2°C.

Detection and counting of Escherichia coli (E. coli) bacteria is an important indicator in assessing water quality and food safety, particularly in the field of environmental health. Conventional methods still require a long time, skilled personnel, and have the potential to cause subjectivity in microscopic observations. This study aims to design and build a digital microscope system equipped with an automatic bacterial counting system based on Artificial Intelligence (AI). The use of this technology is expected to accelerate microbiological analysis, improve detection accuracy, and reduce subjectivity in the manual counting process. The study was conducted using an experimental approach with the System Development Life Cycle (SDLC) method. The dataset consists of 3,011 bacterial images divided into 74% training data, 13% validation data, and 13% test data. The object detection model uses YOLOv11 integrated with Roboflow for annotation and dataset management. Test results show that the model achieved a detection accuracy of 94.1% on the test data, indicating good performance in identifying and counting E. coli colonies. The system is also equipped with a Streamlit-based interface to facilitate users in visualizing detection results in real-time. Thus, the design of this AI-based digital microscope can be an effective and efficient solution to accelerate and improve the accuracy of microbiological analysis, especially in the detection of E. coli bacteria in the fields of environmental health and food safety.

Intestinal diseases such as polyps, esophagitis, and ulcerative colitis may lead to serious complications when they are not detected early. Endoscopy provides important visual information for diagnosis; however, manual interpretation still depends on clinical expertise and requires time. This study aimed to develop an automatic intestinal disease classification model based on Convolutional Neural Network (CNN). The study used a Research and Development method consisting of data collection, preprocessing, model training, evaluation, and web interface implementation. The dataset was obtained from Kaggle and consisted of 6,000 endoscopic images categorized into normal, polyps, esophagitis, and ulcerative colitis. Each class contained 1,500 images, divided into approximately 87% training data and 13% testing data. The model was trained for 15 epochs and evaluated using accuracy, loss, confusion matrix, and single-image testing. The results showed stable validation accuracy in the range of 98-99%, while single-image testing produced confidence scores from 99.91% to 100%. This system is recommended as an initial endoscopic image classification aid, with further development involving a random-image class and an examination history database.
