Now, washing carpets no longer requires a lot of human power. Just one person can wash carpets on a large scale at the same time as three human workers. By using this carpet brush machine, the job of cleaning carpets will be easier and faster. The aim of designing this machine is a form of innovation and creativity in a carpet brush machine with an electric motor drive. The machine is made with the addition of a detergent channel tube to make work easier and increase efficiency. The working principle of this carpet brushing machine is that when the motor is turned on, a pulley with a size of Ø 76.2 mm will rotate with a rotation of 1400 rpm, followed by a belt with a size of 24 inches to rotate the pulley on the shaft with a rotation of 703.5 rpm with a pulley size of Ø 152 mm. The rotation will be continued by the shaft, and the brush will rotate to clean up dirt or stains on the carpet. In making this machine, we obtained a motor power of ½ HP and a rotation of 1400 rpm. This machine has dimensions of 580x380x980 mm and uses a belt and pulley transmission with brush components. This carpet washing machine is used for MSME businesses (micro, small and medium businesses)Sir AndersonKhairul AmriFerdi Nanda Hafni

In this paper, a Multiple-Input-Multiple-Output (MIMO) antenna that can work in Ultra-Wideband (UWB) technology is presented. The antenna can work in frequencies of 3.1-10.6 GHz, has dual bands notched, and in small dimensions at once. The antenna is made in size 34 x 34 x 1.6 mm using a 4-element planar monopole antenna with L-shape and C-shape slits on the radiator. This antenna research was designed and simulated using CST Studio Suite 2019. The design results were fabricated for testing through a Vector Network Analyzer and Anechoic Chamber. The ground plane on the rhombic slot-shaped antenna by utilizing the slot on the antenna radiator produces notched bands from simulations at 3.39-3.64 GHz (WiMAX) and 4.57-5.82 GHz (WLAN). The fabricated antenna has a bandwidth impedance value through S11 <-10 dB in the range of 2.7-12 GHz, including the frequencies of the generated notched bands. With the resulting mutual coupling < -16.51 dB in the measurements of the fabricated antenna and the resulting bandwidth impedance reaching -50 dB at a frequency of 3.05 GHz. This UWB MIMO antenna produces Envelope Correlation Coefficient (ECC) < 0.4, forms an omni-directional radiation pattern, has a gain of 2.6 times at a frequency of 7.01 GHz, a consistent VSWR value of 1.6 at a frequency of 5.6-12 GHz outside of the resulting nocthed bands, and a Total Active Reflection Coefficient (TARC) that reaches -24 dB at a frequency of 7.2 GHz. The results of this paper can be an illustration in making UWB MIMO antennas that have dual bands notched with small dimensions and complex antenna performance that works well in UWB applications.Wahdina JamilFirdaus NursalYulindon yulindon

This research aims to design an off-grid PLTS system for garden lighting based on IoT that is efficient and effective. This system will use IoT technology to control garden lights automatically based on light levels and time. This Off-Grid PLTS system will be designed based on the energy needs of garden lighting, solar panel and battery capacity, as well as a lighting control system. The results of research on solar panels tested for three days at 06:00 to 18:00 from the results of the first day of research obtained when the weather conditions were clear, the light level was obtained, namely 74000 lux with the power obtained 25.78 watts when charging the battery and when it rains, you get a light level of 800 lux with a charging power of 1.78 watts. From this it can be concluded that the effect of light intensity and weather on solar panels has an effect on charging the garden lamp battery. From the research results, charging the garden lamp battery with 12 V 35 Ah, the charging time is 21 hours 43 minutes with an average charging current of 1.92 A and battery discharge is obtained from research on the state of the automatic light, the battery discharge time is 19 hours 25 minutes with an average current 1.41A average. Bright light battery discharge time 18 hours 2 minutes with an average current of 1.55A.Muhammad TaufikJunaidi AsrulRiza Widia

https://jpr-pnp.com/index.php/jpr/article/view/307
Technological developments are currently increasingly rapid and the impact of these developments is that various kinds of design technologies will emerge, especially in the fields of mechanical engineering and automotive methods. Therefore, a lot of research and analysis is needed, one of which is the braking load on the drum braking test equipment through brake pressure parameters using a GX 160 robot type machine. The aim of this research is to determine variations in the braking test equipment on load. The method in this research is data collection through literature study, observation and experimentation. The type of tool in this research is a drum braking test tool. In this study the load was varied from 0 gr to 1300 gr. The research results showed that torque level values ranged from 1,225 Nm to 6.37 Nm, power values ranged from 21,142 Watts to 652,725 Watts, and different rpm rotations due to additional load would reduce the rotation (rpm) ranging from 1663 to 979 rpm, and It was obtained that Pertamax fuel consumption levels ranged from 0.157 ml/s to 0.862 ml/s and Pertalite fuel consumption ranged from 0.157 ml/s to 0.961 ml/s.Muchlisi NalahuddinRidwan MaulanaRiza MuharniIkhsan -
