Abstract

Stunting is a description of chronic malnutrition during growth and development from early life. Many factors can cause stunting in toddlers, such as toddler characteristics and socio-economic factors. This observational research was conducted in Sengkong Village, Sesayap Hilir District, Tana Tidung Regency. There is a lack of knowledge among village residents about stunting, so KKN students at the University of Borneo, Tarakan, collaborate with the village Community Health Center to carry out stunting prevention health education activities. This activity contains information about preventing and handling stunting appropriately. Then there is the impact of inequality that occurs if you do not implement a healthy and clean lifestyle which can cause stunting in children. Apart from that, KKN 01 UBT students also participated in providing appropriate, cheap complementary breast milk food to the residents of Sengkong Village. From this activity, the results and targets that KKN students want to achieve are citizens who have high enthusiasm so that this health education activity runs smoothly. Village residents no longer feel strange and know about how to prevent stunting. As well as, providing appropriate complementary foods for breast milk.

Abstract

Conveyor belt is a material handling tool that is widely used in minning industry. The tool consists of belts or tires made of various types of materials that are resistant to the transportation of solid objects or coal. In order to drive the conveyor, a 3-phase induction motor is needed. PT. Mitrabara Adiperdana used induction motors on each conveyor including conveyor 06. With consumer demand, motors continue to operate to drive conveyors in transporting coal on stockpiles filling barges. The number of berges filled makes the motor continue to operate to move the conveyor for up to one full day. Therefor, it is necessary to analyze the power of consumption and performance level of the motor on conveyor 06, because if there is demage to the motor, the production process on conveyor will be hampered. From the primary data obtained in the field by making direct measurements and obtained the calculation results, the power value is 35.058 Kw when the conveyor is not loaded and 81.80 kw when the conveyor is loaded. With the result of power used when loaded, the calculation of efficiency is 69,45%. Whith this value, the conveyor motor 06 operates less effectively. It is stated be effective when the efficiency value is between 80% and 100% of the effeciency value on motor rating rate.

Abstract

The 3-phase induction motor is a commonly used motor type in various industries due to its advantages in cost, size, and durability. Despite its significant benefits, such as high torque and good efficiency, this motor is still susceptible to several factors that can affect its performance, with load changes and overloads being among the primary causes. Overloads can result from system overload, lack of maintenance, or suboptimal environmental conditions. The impact of these overloads can lead to reduced efficiency and torque in the 3-phase induction motor, potentially harming the overall system performance. This study focused on using braking loads as a form of load testing. The method implemented involved automatic measurement and calculation, displaying outputs such as slip, input power, induced torque, output power, and efficiency. Based on the results of this study, variations in the applied load affected the motor's torque values, with torque increasing as the load was periodically increased: at 75% load, the torque was 0.857 Nm; at 100% load, it was 0.947 Nm; and at 125% load, it was 0.936 Nm. The motor slip values at 75%, 100%, and 125% loads were 9.3%, 10.8%, and 12%, respectively. The input power values at 75% load were 530.6 Watts, at 100% load were 587.54 Watts, and at 125% load were 623.57 Watts. The efficiency values at 75% load were 23.23%, at 100% load were 22.77%, and at 125% load were 20.85%. From the data obtained, it could be seen that the input power continuously increased with the load, the motor slip increased, and the best efficiency occurred when the motor operated at a 75% load.

Abstract

In general, traffic light regulations (traffic tights) currently use fixed times where the lights are set to work alternately at fixed times, without paying attention to traffic flow conditions, for example at four intersections in each direction of the road the duration of the light is green, yellow, red at the same time. In this condition, there is a long queue on one side and a very short queue on the other, so setting the time duration equally will result in unnecessary stopping time. The aim of this research is to calculate the timing of traffic lights in order to identify obstacles and determine the performance of intersections based on the volume of traffic flow during the morning peak hours. The solution method is to calculate traffic flow, cycle time, saturation flow, signalized intersections, using secondary data. The author also uses references from the book (MKJI 1997) for calculations that comply with the provisions. So, the results obtained at the green light at intersection 1 for 33 seconds, the green light at intersection 2 for 33 seconds, the green light at intersection 3 for 21 seconds, and the green light at intersection 4 for 18 seconds, with yellow lights at all intersections for 3 seconds, with a value of the degree of saturation each phase, namely north 0.89, east 0.90, south 0.87, west 1.22.

Abstract

The Dahlander motor is an asynchronous AC motor that operates at two or more distinct rotational speeds, making it different from standard three-phase motors, which generally maintain a single speed under the same power conditions. This motor features a squirrel-cage rotor design and is integrated with a programmable logic controller (PLC), which simplifies wiring systems and allows operational adjustments without altering the wiring layout. However, an additional component, the selector switch, is also employed. This switch controls the motor's rotational direction, enabling it to rotate either clockwise or counterclockwise. The study utilizes a quantitative approach with a developmental design to assess the performance of the Dahlander motor control system. The system functioned as expected, with the selector switch responsible for changing rotational direction. In the right position, pressing the ON 1 button activates contactor 1 for slow clockwise rotation, while pressing ON 2 activates contactors 2 and 3 for fast clockwise rotation. In the left position, pressing ON 1 activates contactor 4 for slow counterclockwise rotation, and pressing ON 2 activates contactors 5 and 6 for fast counterclockwise rotation. The measured rotational speeds were as follows: during slow clockwise rotation, the rotor reached 1494 rpm, while for fast clockwise rotation, it hit 3055 rpm. During slow counterclockwise rotation, the rotor speed was 1456 rpm, and for fast counterclockwise rotation, it reached 3050 rpm.

Abstract

The three-phase induction motor is a prevalent electrical machine utilized across various industrial applications. Notably, the surge current of the induction motor can range from five to seven times the nominal current. This research aims to address this issue by identifying an appropriate three-phase induction motor. One effective method for operating three-phase induction motors is through the implementation of a Variable Speed Drive (VSD). This study develops an induction motor starting system utilizing VSD technology to mitigate the surge current associated with three-phase induction motors. Frequency and duty cycle variations were tested to evaluate their impact. Adjusting the frequency from 25 to 75 Hz at a VSD output voltage of 220 V resulted in a current reduction of 0.74 A. Conversely, modifying the duty cycle from 10% to 100% at a frequency of 50 Hz led to an increase in current of 1.136 A.

Abstract

Electricity is a very essential need for every element of society in this modern era, with electricity, various kinds of work can be easily done. However, in electricity distribution, there are often disturbances that can be detrimental to consumers, One of the power lines that usually experiences interference is the Low Voltage Network (JTR) line. JTR is a transmission network with a low voltage classification between 220 volts and 280 volts. In this transmission, various kinds of disturbances often occur, such as overvoltage and voltage drops. In this research, the author discusses the overvoltage protection system using Proportional Integral Derivative (PID) control. PID control is a simple control method that several researchers have developed to overcome various electrical problems in this modern era. For this reason, the researcher will develop PID as a protection system to overcome overvoltage disturbances in JTR transmissions. The appropriate PID parameter value to overcome overvoltage in this study is the value Kp = 5; Ki = 0,3 Kd = 0.01, where the system is able to protect the overvoltage according to the setpoint value 220 volts.

In general, traffic light regulations (traffic tights) currently use fixed times where the lights are set to work alternately at fixed times, without paying attention to traffic flow conditions, for example at four intersections in each direction of the road the duration of the light is green, yellow, red at the same time. In this condition, there is a long queue on one side and a very short queue on the other, so setting the time duration equally will result in unnecessary stopping time. This research uses an experimental method which is carried out through the stages of procurement, assembling and carrying out trials. By using a Programmable Logic Controller (PLC) and User Interface (UI) to control and monitor the traffic light system at road intersections with the aim of designing and simulating the traffic light system at intersections manually using GX-Developer software and GT-software Designer3. PLC is used to automatically control the work of traffic lights which regulates the operational time of traffic lights which can respond and follow all commands given by the UI system. So testing the light timing settings at intersections can be set directly in the UI system with the timer in the traffic lights program, the timer from the calculation results, and the timer on the stopwatch having relative time differences. So, the real timer results were obtained on the stopwatch at the green light at intersection 1 for 41,79 seconds, the green light at intersection 2 for 41,79 seconds, the green light at intersection 3 for 25.77 seconds, and the green light at intersection 4 for 21,89 seconds. with yellow lights at all intersections 3 seconds, and red lights at all intersections only 1 second as the delay time between red and green lights at one intersection to another
