Abstract

A device that has the basic function of moving a fluid from one container to another is called a pump. In pumps that play an important role is the impeller, now there are many modifications and innovations of pump impellers to support every industrial need. The purpose of this study was to determine the effect of differences in rotational speed variations, design variants of the impeller, and temperature variations set in such a way on the performance of centrifugal pumps. The impeller used in this study is a semi-open impeller with a total of 3 blades that uses a variable spacing of 2 mm, 3 mm, and 4 mm interfering gaps and a motor rotation of 1500 rpm, 2000 rpm, 1800 rpm, and temperature variations of 30 ° C, 40 ° C and 50 ° C. By using an electric motor as the driving force, the type of flow is radial flow, and the pipe diameter is inch. The highest head value that can be produced by this study is 15.70 meters with an electric motor speed setting of 2500 rpm. The highest capacity is 47 LPM at a rotational speed of 2500 rpm. The temperature variation achieved at 30 ̊ C was 2.3 meters and became the highest head. From the analysis of the pump with the impeller gap, the greater the blade gap on the impeller, the smaller the head, capacity, and efficiency produced by the pump.

Abstract

Pumps are equipment that functions to move fluid flow from one place to another. In pumps that play an important role is the impeller, now there are many modifications and innovations of pump impellers to support every industrial need. The purpose of this study was to determine the effect of the impeller with variations in blade curvature on the performance of a centrifugal pump using variations in motor rotation and temperature. In this study, the type of impeller used is an impeller with a total of 4 blades using a blade curvature of 60°, 70°, 80°, and 90° with a motor rotation of 1500 rpm, 1800 rpm, 2100 rpm, and temperature variations of 40° C, 50° C and 60° C. The driving motor used is a motor, the pump that will be used is a radial flow centrifugal pump with a suction and discharge pipe size of inch. The results of this research are the highest head on the impeller with variations in blade curvature is 11.36 meters at a rotational speed of 2100 rpm, a capacity of 37 liters per minute at a rotation speed of 2100 rpm, and an efficiency of 13.60% at 2100 rpm. For the highest head temperature variation of 5.35 meters at a temperature of 40° C. From the analysis of pumps with variations in the curvature of the impeller blades, the larger the blade gap on the impeller, the smaller the head, capacity, and efficiency resulting from the related pump.

Abstract

Trainer is a tool used to support learning activities, training, and introduction of materials in education. In general, trainers or props are widely used in the world of education, namely to support educational methods that use methods of application of theory by means of practice or trials. Where it is necessary to make a 4-step gasoline motor trainer with the aim as a means of practice and to analyze the work process and function of a 4-step gasoline motor. Research design 4-step gasoline motor trainers using development methods (researtch and development). While the analysis of trainer testing uses descriptive methods. In the trainer design process is started with the frame design process, cutting the materials used, welding process, smoothing process, and painting process and the last is the process of assembling all trainer components. The results obtained in the implementation of research and testing resulted in a tool in the form of a 4-step gasoline motor trainer made from galvalume 4x4 iron, and a 4-step gasoline motor type MCN 110cc. While the process of analysis of the results of 4-step gasoline motor trainer testing is obtained with the results of all component mechanisms, including valve mechanisms, transmission mechanisms, and clutch mechanisms can work properly and normally according to initial planning.

Abstract

Watering plants on agricultural land by applying IoT application that can be monitored on smartphone is veri necessary for farmers to faciliitate farmers to monitor and care for plants easily, effectively and efficiently. The purpose of this research to design and make watering devices for chili and tomato plants that can watering automatically IoT based. The research method used is an experimental method designed using esp32 as the main control module of the system, humidity sensor YL-69 to measure soil moisture, ultrasonic sensor HCSR-04 to control water availability in reservoirs, and blynk application as a display on smartphone. The result of research on the design of automatic watering on chili and tomato plants carried out for 3 consecutive days starting at 07:00 WIB to 17:00 WIB. The result of research on the design of watering plants for chilies and tomatoes can function well and can work with adc values of > 600 pumps on up to < 600 pumps off.

Abstract

This research aims to develop and research further about the potential of wind in Jombang to be used as analternative to wind power plants by utilizing the domed swivel mosque. The method in this research is experimentalresearch related to science and engineering technology, namely the making of a mosque turning dome as an alternativeto wind power generation. This tool utilizes the spinning dome of a turning mosque as a producer of motion energywhich is connected to a dc generator using gear and chains as a transformer of rotary motion energy into electricalenergy that produces dc electricity output. The DC electricity is supplied to the Buck boost converter to be regulatedand stabilized the voltage entering the charger module to charge the battery. The output from the battery is then insertedinto a step up step down to be regulated and the voltage is stabilized to 12 v towards the volt ampere meter input as atool to read the voltage on the battery and the current on the lamp. Based on the results of this study, it can be found thatthe blow angle of the blower against the dome 30 ° to the dome is less effective, if the blow angle of the blower againstthe dome is 40 ° it has good effectiveness and greatly affects the stability and speed of the dome rotation and theincrease in load applied to the dc generator results in drop voltage so it greatly affects the supply to the battery.
