Abstract

Isolator memiliki peran penting dalam sistem tenagalistrik, khususnya untuk mencegah terjadinya gangguan pada sistemkelistrikan, seperti arus bocor dan flashover. Penelitian ini bertujuanuntuk menganalisis pengaruh posisi sirip pada isolator berbahanPolyethylene terhadap distribusi medan listrik, arus bocor, dantegangan flashover dalam kondisi kering dan basah. Tiga variasiposisi sirip yang diuji, yaitu di bagian atas (Tipe A), di tengah (TipeB), dan di bawah (Tipe C) dengan geometri isolator yang sama.Simulasi distribusi medan listrik dilakukan menggunakan perangkatlunak FEMM 4.2, sedangkan pengujiaan arus bocor dan teganganflashover dilakukan di Laboratorium Tegangan Tinggi UniversitasBrawijaya. Hasil menunjukkan bahwa posisi sirip mempengaruhiperforma isolator secara signifikan. Isolator dengan sirip di posisibawah menghasilkan medan listrik yang lebih kecil sehingga memilikiarus bocor yang lebih kecil serta tegangan flashover yang lebih besardari tipe lainnya. Hal ini menunjukkan bahwa penempatan sirip diposisi bawah lebih optimal dalam meningkatkan kinerja isolatorpolyethylene. Penelitian ini memberikan rekomendasi desain isolatoryang lebih andal untuk digunakan pada lingkungan dengankelembaban tinggi.Kata kunci: isolator polyethylene, posisi sirip, arus bocor, flashover,medan listrik.

Abstract

Strawberries (Fragaria sp.) have high economic potential, but cultivation in lowlands is hampered by climate factors, such as temperature and solar radiation intensity. Hydroponic cultivation can be a solution to overcome this obstacle by providing measured nutrients according to plant needs. This study developed an automatic tool that measures nutrients based on dissolved particles (PPM) using the Sen044 TDS sensor, with Arduino Uno as a microcontroller and two peristaltic pumps for nutrient distribution. This tool is operated with a 12V 2A power supply and is designed to achieve a nutrient setpoint of 900 ppm. The control system used is Mamdani fuzzy logic, which includes fuzzification, rule base, inference, and defuzification. The fuzzification method applied is Min-max, while defuzification uses the Centroid method. The test results show that the nutrient control system has an accuracy of 94.65% in achieving the setpoint. The test also produces data on time constant, dead time, and steady state gain. For example, with a nutrient input of 700 ppm, the system exhibited a time constant of 1.63 seconds and a steady state gain of 18.51%/V with an output voltage of 3.75 volts. Keywords: Hydroponics, Fuzzy Logic, Nutrition Control System.

Abstract

LTE is an Internet Protocol (IP) based technology with increased speed and spectrum efficiency compared to previous technologies. The 700 MHz frequency is the most ideal frequency for LTE in Indonesia. This is based on wider coverage, wide bandwidth availability, and smaller propagation loss compared to other frequencies. Determining the number of sites to be used refers to coverage calculations and capacity dimensioning. Then the location is chosen based on the existing site location in Kediri City so as to minimize blank spot areas. Then this planning uses Atoll Radio Planning software with the Okumura-Hatta propagation model. Dimensioning calculations show that the number of eNodeBs needed in this plan is 23 eNodeB sites. The simulation results show that the plan has a Received Signal Strength Indicator (RSSI) value of -66.36 dBm with a signal level that is categorized as good, namely >-90 dBm capable of covering an area of 65.62 km2. The average Reference Signal Receiver Power (RSRP) value obtained is -98.98 dBm. The average throughput value obtained was 22.354 Kbps. Keywords: LTE, Atoll, RSSI, RSRP, Throughput

Abstract

The development of the coffee industry in Indonesia is growing rapidly. In the coffee industry, the quality and consistency of coffee flavor is very important where the right proportion of coffee and other additives is a major factor. In addition, operational efficiency in the coffee industry is also important to maintain competitiveness and optimal profits. This can be achieved by managing material stock and recording accurate weighing results so that stock opname activities are needed. One of the coffee shops that implement stock opname in Malang City is Toko Kopi Jaya. The calculation of existing material stock at Toko Kopi Jaya is currently still carried out in a conventional way where the basic ingredients of drinks such as espresso and milk are weighed manually at the end of operating hours. Manual calculations cause problems, such as errors in recording the results of weighing the stock of ingredients. The Internet of Things (IoT) can provide many innovative solutions to improve efficiency in various industries. In the context of the coffee industry, the application of IoT technology to digital scales can provide an effective solution to overcome the problem of inefficient calculation of the current stock of ingredients. The design of IoT-based coffee digital scales was successfully carried out for the automation of material stock reduction using the main components in the form of load cell sensors, HX711 modules, LCDs, and push buttons controlled by ESP8266. The reading data from the load cell sensor is received by ESP8266 and sent to Google Sheet. The load cell sensor used in this IoT-based digital scale has an accuracy rate of 99.964% and the system has an accurate rate of 99.7%. The integration system of IoT-based digital coffee scales with Google Sheet via Wi-Fi connection allows real-time recording of material usage and automatic reduction of material stock.

Abstract

Penggunaan Progressive Cavity Pump (PCP) telah menjadi pilihan utama dalam mengalirkan berbagai jenis fluida, terutama cairan berat atau kental dan pengoperasian pada fluktuasi tekanan. Hal ini disebabkan oleh kemampuannya untuk mengatasi tantangan yang dihadapi dalam mengalirkan fluida dengan viskositas tinggi dan pengoperasian pada tekanan yang berfluktuasi, serta kemampuannya untuk memberikan aliran yang stabil dan berkelanjutan. Motor penggerak yang umum digunakan dalam aplikasi PCP adalah motor induksi 3 fasa. Motor induksi 3 fasa banyak digunakan untuk menggerakkan rotating equipment di industri karena keandalannya, efisiensinya, konstruksi yang sederhana, harga yang lebih murah, dan mudah dalam perawatannya. Namun, pengoperasian motor induksi 3 fasa untuk aplikasi PCP memiliki kebutuhan akan pengaturan kecepatan serta dapat mempertahankan kecepatan dan torsi motor dalam kondisi yang dinamik. Oleh karena itu, penelitian ini bertujuan untuk merancang dan menganalisis penggunaan sebuah Variable Speed Drive (VSD) dengan metode Direct Torque Control (DTC) untuk aplikasi PCP menggunakan MATLAB dan Simulink. Hasil dari penelitian ini menunjukkan bahwasannya metode DTC dapat mencapai kecepatan yang diinginkan serta mempertahankan kecepatan pada kondisi dinamik pada motor induksi 3 fasa berbeban PCP dengan mengontrol torsi motor dan fluks stator secara langsung. Kata kunci: Motor Induksi 3 Fasa, Variable Speed Drive (VSD), Direct Torque Control (DTC), Progressive Cavity Pump (PCP)
