Abstract

Advances in renewable energy sources have led to the development of more powerful power plants using fewer fossil fuels to protect the environment and reduce the amount of greenhouse gases produced. Some of the most common renewable energy sources that have been developed are water, sun, wind and biomass. In this research, an analysis was carried out on how water flow from the regional drinking water company (PDAM) can produce electrical energy. System design, system work and analysis of the effectiveness of the pico hydro type hydroelectric power generation system using household PDAM water discharge. The method is carried out by installing branching pipes, namely the channel leading to the generator and the channel leading to the residence. The author's research objectives are divided into three, namely measuring water discharge at 4 times, namely morning, afternoon, evening and night, calculating voltage, current and electrical power, and determining the battery charge at these 4 times. The results obtained are a water discharge of 7.6 liters/minute with the largest electric current at night being 0.04A, the 5Ah battery charging time is 125 hours, this charging will not continue as long as the use of PDAM water and free electrical energy stored in the battery from a 12V marine generator. It can be concluded that night is the right time to charge the battery.

Abstract

The problem with transformers, especially those used in the supply of electrical power supply to high-rise buildings, is in the output voltage of the distribution transformer. Lifetime and continuous use cause a decrease in performance and transformer performance in supplying usage loads. There needs to be a solution to the transformer performance problem in order to save transformer efficiency costs on the use of electrical power against the load used. The research method used is to purify the transformer so that the transformer performance remains stable in supplying the load. The step in purification is to take measurements before and after at the transformer terminals to LVMDP. The result obtained is a voltage drop of 39% but still within the range of >30 kV, with an average load of 1145A. The average 3phase voltage after data purification is 405 Volts, after a purification period of 2 operational years it drops to 402 Volts. As for the 1phase voltage, data is obtained after purification of 235 Volts down to 231 Volts. The temperatur of the HV 400C transformer has increased to 44,80C.

Abstract

The need for information in the field of education is crucial in determining the progress of an institution. With the utilization and application of information technology, data sets can be interconnected. The Academic Information System at SMP Gemilang Modernland is an academic information system that must be implemented for easier access by students, teachers, school administrators, and the wider community seeking information about the school. The delivery of information, such as teacher data, student data, class representatives, school information, payments, and classes, is currently not as efficient as desired, resulting in the accumulation of data that requires a considerable amount of time to process. To address these challenges, a system is required. The system is designed using the PHP programming language with a MySQL database and employs the Rapid Application Development (RAD) method. The outcome of this research is a web-based academic information system that is needed by teachers, students, staff, and external communities, enabling easy and swift access without constraints of time and place.

Abstract

The introduction of this film script writing format aims to introduce AR augmented reality to students at Teruna Integrated Vocational School, Borces 1, majoring in broadcasting. The low intention to learn is influenced by learning media such as Power Point presentation texts, which are displayed via projectors, student web portals and practicums. Based on the results of the questionnaire given to students, the media used was felt to be less interesting, and this influenced the students' lack of understanding of the material presented by the teacher. To overcome this, more interactive learning media is needed, utilizing augmented reality technology. The method for building system development applications uses the Multimedia Development Cycle (MDLC), while the application creation method uses marker based tracking. Place the marker on two cubes that will be directed at the camera to produce objects, namely: EXT, INT, Character, Actionlines, Dialogue. By applying augmented reality technology to the application for introducing film screenplay writing formats, there are also advantages, namely that we can display film screenplay writing formats in 3D and add information regarding the introduction of screenwriting formats.  This makes it easier for students in the learning process to introduce the film screenplay writing format.

Abstract

Currently, many automatic and practical tools have been created. Including in the world of health, for example baby incubators. Baby incubators are generally used for babies born prematurely. Baby incubators generally still use manual methods in controlling the temperature of the incubator room, for example the temperature in the incubator is above the ideal temperature, or even the temperature is below the required temperature. So the role of the operator, in this case the doctor or nurse, is still dominant. With this problem, we need a system that can control and monitor the baby incubator temperature based on web and SMS, making it easier for doctors and nurses to monitor the baby's condition. This tool will be developed to be web and SMS based. With the development of this tool, it is hoped that it can help doctors and nurses in monitoring the condition of babies in incubators.

Abstract

In this day and age, photography is very popular in Indonesia, many people want to document the moments of their activities with camera devices. Sometimes, the use of the camera that is arbitrary or does not follow the rules can cause damage to the camera. Lack of knowledge about cameras makes amateur users confused if there are problems that arise if there is damage and in the end the user decides to buy a new one because of the user's ignorance in repairing the camera. Camera experts or technicians are people who can check and repair cameras. However, limited expert readiness is not always available 24 hours, especially in locations far from settlements, it will be complicated to consult an expert or camera technician at an important time in the event of a camera malfunction. Therefore, the author makes an Expert System for Diagnosing Damage to the Camera using the Dempster Shafer Method. The method used is Dempster Shefer where this method focuses on the magnitude of the belief that a symptom of damage supports the diagnosis of certain damage. The expected results can help camera users diagnose camera malfunctions and their solutions.
