Abstract

Dump Accumulator on RFID system built from Register and counter. On the block counter requires a series of NAND, Half Adder, and D flip flop. This paper compares the two discrete schematic designs for a combination of NAND 4  logic  input  gates.  Schematic  design  made  work  at  5Mhz  frequency  and maximum voltage of 3.3volt with Lt spice XVII application software. The first design uses the AND and NAND 2 logic gate combined inputs. The second design uses a NAND 4 logic input gate that is combined from a horizontally arranged (PMOS) and vertical (NMOS) CMOS component. Overall the second design has many advantages over the first design. The simulation results of the two designs show that the first design has advantages in the test of time (speed test), T fall is balanced with T rise is 12ns, total time required 24ns. But power dissipation  is  large  (55,43pW).  While  in  the  second  design,  it  has  a  few advantages of small CMOS components, a simpler schematic design, a small power dissipation (11.15pW), speed at T fall (20ns) larger than T rise (2ns), total time required 22ns. Keywords:   gerbang   logika   NAND,   Desain   diskrit,   Trise,   Tfall,   Power Dissipation

Abstract

Internet Of Things (IoT) adalah sebuah sistem yang terdiri dari teknologi pemroses, jaringan internet, perangkat pintar. Perangkat berbasis IoT ini digunakan untuk mengirimkan data dengan bantuan internet, sehingga bisa digunakan untuk mengendalikan objek dari jarak jauh. Salah satu implementasi Teknologi IoT yaitu pada akuarium untuk pemeliharaan dan perawatan ikan hias yang bisa dilakukan dari jarak jauh. Penelitian ini dikhususkan untuk mengendalikan suhu air dalam akuarium, pencahayaan, dan pemberian pakan secara otomatis.Sistem ini menggunakan Aplikasi Blynk sebagai interface untuk mengatur dan memonitor suhu air, pencahayaan, dan waktu pemberian pakan. Pengontrol yang digunakan adalah Mikrokontroler NodeMCUESP8266. Tahapan proses dilakukan dengan menguji tiap bagian yang menjadi keluaran. Pengujian bagian sensor suhu DS18B20, diperoleh rata-rata selisih nilai suhu sebesar 0.37 °C. Dari pengujian relay dan heater terbukti bahwa relay mampu mengkondisikan heater bekerja secara otomatis. Pada pengujian LED WS2812B dapat mengeluarkan warna cahaya yang sesuai dengan nilai kecerahan warna pada aplikasi Blynk, dengan rata-rata delay saat kondisi otomatis lampu mati 1.61 detik dan lampu menyala 1.53 detik. Pada pengujian motor servo untuk pakan, rata-rata delay 1.56 detik secara otomatis.

Abstract

Wind energy is one of the green energy sources that can decrease reliance on fossil fuels such as oil and coal. Wind turbines harness the kinetic energy of the wind and transform it into mechanical energy, which is subsequently converted into electrical energy using a DC generator. The generated DC voltage is transformed into AC voltage by an inverter unit. However, conventional inverters generally produce square-wave outputs with high total harmonic distortion (THD), whereas AC power systems ideally require sinusoidal waveforms with low harmonic content. This research proposes the design of a renewable energy–based power supply system capable of generating both DC and AC voltages for low-power applications. The novelty of the proposed system lies in the use of a five-level inverter with fewer switching devices than the cascaded inverter topology, combined with a T-model inductive-capasitive-inductive (LCL) filter to suppress harmonic distortion at the inverter output. The method involves modeling and simulating the system design using MATLAB Simulink. Simulation results show that the five-level inverter produces an output voltage amplitude of 270 V at 50 Hz with a THD of 28.48 %. After applying the LCL filter (L1 = L2 = 0.01 H and C = 1 mF), the THD decreases to 2.56 % for a 10 Ω resistive load, 2.61 % for an RL load (100 Ω, 0.8 mH), and 2.54 % for an RC load (10 Ω, 1 µF). These values comply with the IEEE 519 standard requiring THD below 5 %. Therefore, the proposed system has potential for small-scale renewable energy applications.
