Abstract

A double-speed motor is a type of asynchronous AC motor designed with two or more windings. The presence of two separate windings causes three-phase double-speed motors to have a significantly larger physical size compared to three-phase single-speed motors of the same power rating. Numerous studies have investigated the impact of the rewinding process on the efficiency of single-speed induction motors. However, limited attention has been given to double-speed induction motors. Addressing this research gap, the present study focuses on two primary objectives: first, to analyze the impact of rewinding on the performance characteristics of double-speed induction motors; and second, to evaluate the operational performance of these motors after undergoing the rewinding process. In this study, the rewinding process utilized copper wire with a diameter of 0.50 mm, wound using a mold to create a total of 52 windings. Performance testing revealed the following results: under no-load conditions with slow rotation, the motor exhibited a current of 1.3 A, a frequency of 50.45 Hz, a power factor (cos φ) of 0.86, and a speed of 1515 RPM. When a load was applied under fast rotation, the motor demonstrated a current of 1.9 A, a frequency of 50.29 Hz, a power factor (cos φ) of 0.997, and a speed of 2949 RPM. The experimental results showed minimal variation in current and frequency between loaded and unloaded conditions, with significant differences primarily observed in rotational speed between slow and fast modes. This behavior is characteristic of double-speed motors, which are capable of operating at two distinct speeds. In fast rotation mode, the speed can reach approximately twice that of slow rotation, highlighting the design's capability to adapt to varying operational demands.

Abstract

Energi listrik menjadi kebutuhan yang sangat penting bagi kehidupan, terutama energi listrik arus bolak-balik atau AC (Alternating Current). Pembangkit listrik yang menghasilkan tegangan AC masih banyak menggunakan bahan bakar fosil yang ketersediaannya semakin menipis. Untuk mengatasi hal tersebut sumber listrik alternatif berupa energi DC (Direct Current) dari baterai dapat dimanfaatkan sebagai sumber energi listrik pengganti bahan bakar fosil. Peralatan yang bisa digunakan untuk memanfaatkan energi alternatif tersebut adalah inverter. pure sine wave menggunakan teknik SPWM (Sinusoidal Pulse Width Modulation). Pada inverter ini diperlukan sebuah osilator. Osilator yang digunakan pada penelitian ini adalah mikrokontroler yang didesain dengan cara memasukan program perintah, sehingga menghasilkan sinyal Pulse Width Modulation (PWM) yang akan mengendalikan MOSFET. Pada inverter ini menggunakan sumber DC 27 Volt dari battery lalu dikonversi menjadi tegangan AC ±220 Volt, memiliki frekuensi ±50 Hz, dan output gelombang yang berbentuk sinus. Tujuan dari perancangan alat ini adalah merubah energi DC menjadi AC dan memiliki output gelombang yang berbentuk sinus. sehingga energi alternatif tegangan DC dapat dimanfaatkan.

Abstract

Industri di Indonesia sedang berkembang pesat baik di sektor besar maupun kecil. Seiring dengan pertumbuhan ini diperlukan peralatan produksi yang efektif guna meningkatkan efisiensi waktu dan biaya. Motor induksi tiga fasa sering digunakan dalam industri karena harganya yang relatif terjangkau dan memiliki keandalan yang tinggi. Namun, disisi lain kelemahannya adalah kecepatan motor induksi tiga fasa yang menurun seiring dengan adanya peningkatan beban. Hal tersebut berdampak pada hilangnya kecepatan konstan motor saat kondisi beban yang bervariasi. Maka, diperlukan suatu pengontrol guna menjaga kecepatan tetap stabil dan meningkatkan performa sistem dalam menghadapi perubahan beban. Untuk mengatasi masalah tersebut Sliding Mode Control (SMC) digunakan guna mengatasi perubahan parameter akibat beban yang fluktuatif. Field Oriented Control (FOC) digunakan guna mengendalikan secara terpisah arus beban motor dan arus penguatan, sehingga fluks dan torsi dapat diatur secara independen. Berdasarkan hasil simulasi dan analisa didapatkan bahwa SMC dengan field oriented control baik digunakan untuk pengaturan kecepatan motor induksi tiga fasa.

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

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.
