The fuzzy logic method is a method that is not much different from the case that resembles the level of thinking of people's logical reasoning. It has two inputs from two different sensors with linguistic values or called membership degrees and the resulting voltage is 0 - 5.5 Volts. The PIR sensor will work optimally at a distance of 4 meters where for the sensitivity of the PIR sensor itself it can react in a time range of 3-4 seconds and for its own range of approximately 4 meters and on the LM35 sensor test that this sensor is better for temperature due to the sensitivity of detecting temperature when compared to a thermometer, this sensor will be able to stabilize the room temperature which is less precise, so that in making the room for automatic cooling the sensor works optimally in a room measuring 4 x 4 meters.

Employees are a company resource to produce services or goods to meet consumer needs. To improve the performance of company resources, companies need to meet the needs of employees and give appreciation to employees who have good performance, one of which is giving bonuses. PT Fiture Teknologi Inovasi is a company engaged in the field of IT solutions. Determining bonuses still uses manual methods and there is no media or tools that can process employee ratings who deserve bonuses. Based on the problems above, the authors made a decision to support a web-based bonus system using the weighted product and weighted sum methods. The result of this system is one employee who has the highest vector v value of the two methods. From the results of the calculation of the data, then the percentage of the method's suitability with the data is calculated.

One type of reptile that is currently developing is the Eublepharis Macularius or better known as the Leopard Gecko. Leopard Gecko is a tame reptile class animal that has a unique pattern on the outer skin of its body. The size of this animal is also not too big but also not too small, around 24 - 27 cm. The breeding of this animal is one of the interesting things to study because the sex of the Leopard Gecko can be influenced through the temperature setting of the egg incubator. Engineering the Leopard Gecko incubator for temperature is one of the interesting implementations of electrical engineering to enliven the Leopard Gecko industry. A simple plastic container can be engineered as a means of monitoring and controlling the temperature of the Leopard Gecko incubator by wireless Xbee. By controlling the temperature of the incubator, the sex of the Leopard Gecko eggs can be monitored. A certain temperature can determine the sex tendency of the Leopard Gecko. A temperature of 26°C can hatch female Leopard Gecko eggs, while a temperature of 32°C can hatch male Leopard Gecko eggs. Some electronic equipment that can be used are such as temperature sensors, microcontrollers, ZigBee, relays, incandescent lamps, and monitors. With this set of electronic equipment, the temperature in the incubator can be monitored and controlled wirelessly.

This study aims to observe and analyze the load of the press machine using a star-delta configuration in a palm oil mill. The press machine is a key component in the palm oil extraction process, and its efficiency is significantly influenced by the motor control system used. The efficiency of the extraction process is crucial as it directly affects production output and operational costs. The star-delta configuration was chosen for its ability to reduce the initial current when the motor starts, thereby increasing motor lifespan and reducing maintenance and operational costs. In this study, the load of the press machine was measured during operational stages to comprehensively assess the performance of the star-delta configuration. Data collected included motor current and voltage during start-up and normal operation. This analysis aimed to determine the extent of initial current surge reduction achieved and load stability during operation. Observations showed that using the star-delta configuration significantly reduces initial current surges, which are often the main cause of motor damage and wear. Additionally, this configuration provides a more stable load during press machine operation, positively impacting overall energy efficiency. Therefore, this study provides valuable insights into the importance of using the star-delta configuration in the palm oil industry and its potential to enhance the performance and operational sustainability of the mill Abstrak Penelitian ini bertujuan untuk mengamati dan menganalisis beban mesin press yang menggunakan rangkaian star-delta di pabrik kelapa sawit. Mesin press merupakan salah satu kunci utama dalam proses ekstraksi minyak kelapa sawit, dan efisiensinya sangat dipengaruhi oleh sistem pengendalian motor yang digunakan. Efisiensi proses ekstraksi sangat penting karena berkaitan langsung dengan output produksi dan biaya operasional pabrik. Rangkaian star-delta dipilih sebagai solusi karena kemampuannya untuk mengurangi arus awal saat motor dinyalakan, sehingga dapat meningkatkan umur motor dan mengurangi biaya perawatan serta operasional. Dalam penelitian ini, dilakukan pengukuran beban mesin press pada tahap operasional untuk menilai kinerja rangkaian star-delta secara komprehensif. Data yang dikumpulkan mencakup arus dan tegangan motor selama proses start-up dan operasi normal. Analisis ini bertujuan untuk menentukan seberapa besar pengurangan lonjakan arus awal yang dicapai dan stabilitas beban selama operasi berlangsung. Hasil pengamatan menunjukkan bahwa penggunaan rangkaian star-delta secara signifikan mengurangi lonjakan arus awal, yang sering menjadi penyebab utama kerusakan dan keausan motor. Selain itu, rangkaian ini memberikan beban yang lebih stabil selama operasi mesin press, yang berdampak positif pada keseluruhan efisiensi energi. Oleh karena itu, penelitian ini memberikan wawasan berharga tentang pentingnya penggunaan rangkaian star-delta dalam industri kelapa sawit dan potensinya untuk meningkatkan kinerja dan keberlanjutan operasional pabrik.

Jetson Nano, a Single-Board Computer or SBC developed by NVIDIA, is used to implement a face recognition system that requires large computing resources. This research aims to analyze the resource usage on the Jetson Nano during the running of the face recognition system, including CPU usage, GPU, memory, and power consumption. Monitoring data was obtained using Jtop software to record real-time resource usage and a wattmeter for electrical power consumption. The results showed that the Jetson Nano CPU performed consistently with an average utilization of 77.14%, reflecting an even distribution of workload. The GPU showed an average utilization of 44.05% with higher fluctuations, indicating variations in graphics workload intensity. Memory was used close to the maximum capacity of 4 GB, with an average utilization of 3.75 GB, indicating efficient memory management. Average power consumption was recorded at 8.56 Wh, confirming the energy efficiency of this device. This study concludes that the Jetson Nano is capable of running the facial recognition system stably and efficiently, although there is room for further optimization on GPU load distribution and memory management. With its high power efficiency, the Jetson Nano is an ideal solution for artificial intelligence-based applications with low power requirements.
