<![CDATA[Air is one of the essential components for the survival of living things, air is a mixture of gases found in layers that surround the earth.Later, We were surprised by the rumors of air pollution happening in Indonesia, Especially in jakarta and beberaqpa other major cities in Indonesia.Without good air will surely be fatal to the respiratory system of humans and other living things on the face of the earth.Carbon (CO and CO2) is one of the materials found in the air and on the ground as carbonate rock, The gas has had a terrible impact on humans and other living things.If a living thing is exposed to that gas in a long time can result in death caused by a lack of oxygen intake. For that, The author performs the design and manufacture of carbon gas levels monitoring tools (CO and CO2) based on NodeMCU ESP 8266.Where the tool works by monitoring CO and CO2 levels that can provide information about CO and CO2 levels that then data from the gas levels will be sent directly to the whatsapp app and also through the LCD display and there will also be a warning alarm from the buzzer.Based on the tests that have been performed, the tool works to maximize the ability to monitor the levels of co and co2 gas sent to the whatsapp app and also be able to provide information via lcd and alarms through the buzzer when the levels of co and co2 exceed the previous threshold when the gas levels have returned to normal then the alarm will cease to sound and become normal]]>

<![CDATA[The door security system using fingerprint is one of the many systems that is often used to add a level of security to school, home and other doors. The door system uses fingerprints as a medium to read or identify so that the door can be opened. Automatic doors with a fingerprint recognition system are a modern solution for securing access to various locations. The implementation of Fuzzy Logic in this tool is used to provide a delay time of 3 seconds in the open state based on the number of fingerprints attached. Arduino Uno functions as the main controller that integrates the fingerprint module and door actuator. The result of this research is a door security system tool that applies a fuzzy logic algorithm and includes a hardware and software design process, including integration of electronic components and development of a fingerprint verification algorithm. Implementation The experimental method is used to test the reliability of the system in user recognition and access. Experimental results show that the system can identify users with high accuracy and provide a fast response in operating the automatic door. The practical contribution of this research is the development of automatic door technology that can be applied in various contexts to increase user safety and comfort.]]>

<![CDATA[Indonesia has vast agricultural and plantation lands, yet the efficiency and productivity of this sector still need improvement. One solution is the application of Internet of Things (IoT) technology in hydroponic systems, allowing for automatic and real-time control and monitoring of plant conditions. This research aims to develop a hydroponic room monitoring system based on the NodeMCU microcontroller with automated nutrient scheduling. The methods used in this study include the design and implementation of an IoT system using NodeMCU, humidity sensors, temperature sensors, and nutrient pumps, as well as the development of a smartphone application for monitoring and control. The research results show that the developed system can accurately monitor hydroponic environmental conditions and automatically provide nutrients according to the scheduled time. The use of this technology is expected to facilitate farmers in monitoring and maintaining hydroponic plants, improving water and nutrient use efficiency, and optimizing crop yields. In conclusion, the application of IoT in hydroponic systems positively impacts agricultural productivity, especially in areas with limited land, and offers a practical solution for urban communities interested in modern agriculture.]]>

<![CDATA[Educational scholarships are financial aid given to students or students to support the financing of their education. Mistakes in the assessment of scholarship recipients are often related to subjectivity and lack of transparency in the selection process. Unclear or inconsistent assessment criteria can lead to unfairness, where some deserving candidates may not get the same opportunities. The number of data used in Determining Scholarship Recipient Students is 10 students. The purpose of the MAUT modification research with geometric mean in producing criterion weights is to improve accuracy, stability, and consistency in the decision-making process. This study also aims to test the effectiveness of the geometric mean method in producing more objective and structured weights, as well as compare it with other traditional MAUT methods such as direct addition or multiplication. The modification of the MAUT method with a geometric mean is named G-MAUT. The results of the ranking of scholarship recipients using the G-MAUT method the first-place scholarship recipient with a final score of 1.0048 was obtained by Student 3, the second-place scholarship recipient with a final score of 0.6260 was obtained by Student 8, and the third-place scholarship recipient with a final score of 0.5048 was obtained by Student 5. This modification under the name G-MAUT allows for a more holistic and comprehensive assessment of potential recipients, ensuring that non-academic aspects are also taken into account proportionately.]]>

<![CDATA[The transformer is a crucial component in the electrical energy distribution system. Therefore, strict supervision is necessary to ensure that the electricity supply network is maintained and safe during operational processes. This research aims to measure the transformer load installed at PT. Sunrise Steel to determine the values of loading, imbalance, power losses, and efficiency of the loaded transformers. This measurement is important to ensure that the values resulting from operational processes do not exceed predetermined limits. Observations over 10 days show that the peak load value during operational time is 66.08%, which can still be categorized as quite good. The load imbalance reached a maximum value of 10.13%, which is categorized as poor since SPLN regulations state that a good imbalance should be below 10%. The percentage of power loss has a maximum value of 0.33%, and the best transformer efficiency reaches 97.17%, which is the highest efficiency value considering several other loss parameters.]]>
