Abstract

Trasformator step down adalah sebuah perangkat elektronik yang memiliki fungsi utama untuk menurunkan tegangan listrik ke level yang lebih rendah. Data yang digunakan dalam analisis ini berasal dari hasil pengukuran di PT. PLN Tarakan yang dilakukan selama beberapa bulan pada tahun 2021, diantaranya bulan Januari, Februari, Agustus, dan September. Data pengukuran ini kemudian diolah dengan menggunakan metode fuzzy untuk mencapai keseimbangan yang diinginkan. Menurut standar Std.446-1980, keseimbangan beban yang diharapkan berkisar antara 5 hingga 20%. Sebelum menerapkan metode fuzzy Mamdani, hasil analisis menunjukkan bahwa pada bulan Februari, transformator YDS 191 memiliki ketidakseimbangan arus beban tertinggi yaitu 46,1%, sedangkan transformator SLM 377 memiliki tingkat ketidakseimbangan terendah yaitu 20,7%. Namun, setelah menerapkan metode Fuzzy Mamdani, hasil analisis menunjukkan perbaikan yang signifikan. Ketidakseimbangan arus beban tertinggi yang tercatat adalah 17% pada transformator YDS 083 di bulan Agustus, sedangkan transformator SLM 241 di bulan Februari mencapai ketidakseimbangan sebesar 2,6%. Hasil ini menunjukkan bahwa penerapan logika fuzzy Mamdani efektif dalam mengurangi ketidakseimbangan arus beban. Hasil ini memberikan bukti yang kuat bahwa penggunaan metode Fuzzy Logic dengan FIS Mamdani mampu menurunkan ketidakseimbangan arus beban hingga di bawah batas maksimum yang ditetapkan oleh Standar PLN Nomor 1 Tahun 1995, yaitu sebesar 20%. ABSTRACT Step down transformer is an electronic device that has the main function to reduce the voltage to a lower level. The data used in this analysis comes from the measurement results at PT PLN Tarakan which were carried out for several months in 2021, including January, February, August and September. This measurement data is then processed using fuzzy methods to achieve the desired balance. According to the Std.446-1980 standard, the expected load balance ranges from 5 to 20%. Before applying the Mamdani fuzzy method, the analysis results showed that in February, transformer YDS 191 had the highest load current imbalance of 46.1%, while transformer SLM 377 had the lowest imbalance level of 20.7%. However, after applying the Fuzzy Mamdani method, the analysis results showed significant improvements. The highest load current unbalance recorded was 17% at transformer YDS 083 in August, while transformer SLM 241 in February achieved an unbalance of 2.6%. These results show that the application of Mamdani fuzzy logic is effective in reducing load current imbalance. These results provide strong evidence that the use of the Fuzzy Logic method with FIS Mamdani is able to reduce the load current imbalance to below the maximum limit set by PLN Standard Number 1 of 1995, which is 20%.

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

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.
