Abstract

Nowadays, electricity consumption in Indonesia still rising the future, as fuel cell energy reserves continue to decline, this has pushed people to switch to new and renewable energy which guarantees the availability of new electricity sources. A Photovoltaic system has been installed in the Electrical Engineering Laboratory with a capacity of 1 kWp. The PV system is proposed as a new source of electricity to support the electricity needs of laboratories other than PLN. This paper compares the modeling that has been done using the Maximum power point tracking (MPPT) algorithm namely Incremental Conductance (IC) and Perturbation & Observation (P&O) in Standard Test Condition (STC) of 1000 W/m2 and a temperature of 25ËšC. The control simulation of the MPPT DC / DC Boost Converter is calibrated to satisfy the 220V/50 Hz PLN grid. The simulation results the MPPT control with the P&O algorithm has output power of 960 W and an efficiency of 99,9 % when using the IC process has 944 W and an efficiency of 98,7%. The P&O was selected to have optimum performance relative to the IC approach in the 1000 Wp PLTS system in the Electrical Engineering Laboratory.

Abstract

Perkembangan antena radar semakin cepat dan beragam, salah satunya adalah antena MIMO (multiple output). Antena MIMO banyak digunakan untuk teknologi 5G  karena efisiensi spectral dan fekuensi yang tinggi. Antena MIMO juga merupakan suatu sistem yang menggunakan multi antena baik pengrim (Transmitter) maupun penerima (receiver) yang bisa mengatasi kelemahan pada sistem komunikasi wireless. Penelitian ini merancang sebuah antena mikrostrip MIMO 2X2 dengan menggunakan patch bowtie untuk mengkonversi frekuensi dari 2,4 GHz menjadi 5,5 GHz dengan menambahkan dual slot segiempat dan single slot segitiga. Hasil simulasi menunjukkan penambahan dual slot segiempat dan  single slot segitiga pada patch antena bowtie dapat menggeser frekuensi kerja dari 2,4 GHz menjadi 5,5 GHz. Dari hasil simulasi antena MIMO 2X2 didapatkan nilai return loss S11 sebesar -46,5 dB, insertion loss S21 sebesar -25,2 dB, bandwidth sebesar 192,2 MHz, VSWR sebesar 1,00 dan gain sebesar 3,11 dBi. Hasil dari pengukuran antena MIMO menunjukkan perbedaan dari parameter antena 1 dan 2. Hal ini disebabkan adanya ketidaksamaan ukuran dari antena 1 dan antena 2. Pengukuran  nilai return loss untuk antena 1 yaitu sebesar -22,32 dB dan -15,63 dB untuk antena 2. Hasil pengukuran insertion loss antena 1 dan 2 memiliki nilai yang sama yaitu -43,5 dB dan untuk lebar bandwidth memiliki perbedaan nilai yaitu 50 MHz untuk antena 1 dan 100 MHz untuk antena 2. Pengukuran nilai VSWR 1 didapatkan nilai sebesar 1,96, VSWR 2 sebesar 1,41. The development of radar antennas is getting faster and more diverse, one of which is the MIMO (multiple output) antenna. MIMO antennas are widely used for 5G technology because of their high spectral efficiency and frequency. MIMO antenna is also a system that uses multiple antennas, both transmitter and receiver which can solving the weaknesses in wireless communication systems. The research designed a 2X2 MIMO microstrip antenna using a patch bowtie to convert the frequency from 2.4 GHZ to 5.5 GHz by adding dual rectangular slots and single triangular slots. The simulation results show that the addition of dual rectangular slots and single triangular slots on the patch bowtie antenna can shift the working frequency from 2.4 GHz to 5.5 GHz. From the simulation results of MIMO 2X2 antenna, the return loss value of S11 is -46.5 dB, insertion loss S21 is -25.2 dB, bandwidth is 192.2 MHz, VSWR is 1.00 and gain is 3.11 dBi. The results of the MIMO antenna measurements show differences in the parameters of antennas 1 and 2. This is due to the difference size of antenna 1 and antenna 2. The measurement of the return loss value for antenna 1 is -22.32 dB and -15.63 dB for antenna 2 The results of the insertion loss measurements for antennas 1 and 2 have the same value, which is -43.5 dB and for the width of the bandwidth has a different value, 50 MHz for antenna 1 and 100 MHz for antenna 2. Measurement of the value of VSWR 1 obtained a value of 1.96, VSWR 2 is 1.41.

Abstract

The development of medical equipment with advanced technology can provide convenience in providing services to the community. One of the equipment that is in the hospital and most often used is an IV. In its use, manual infusion is used to determine the volume of the infusion and must be monitored every hour or even minute by the nurse. This is considered quite difficult, especially in the era of the Covid-19 pandemic where minimal interaction is required from 2 individuals. This is done by utilizing sensor technology to monitor the patient's condition so that the frequency of the nurses checking the condition of the infusion is getting less. Therefore, in this research, manufactured of an infusion monitoring system using aweight sensor (Load Cell) based on the ATMEGA 328 microcontroller was carried out. The sensor of this monitoring system uses a Load Cell Weight Sensor with the HX711 module which is integrated into the ARDUINO UNO MCU. The output of the system is displayed on a 16 x 2 mm LCD as well as a Macro Excel which will display the percentage value of intravenous fluids in the PC and real-time automatic data logging into the macro excel. The infusion used uses Nacl fluid infusion. The test results of the system as a whole show that the data for measuring levels (%) of intravenous fluids can be sent and displayed on the LCD and PC. The incoming data is converted into a table at certain time intervals according to the user's choice into the operator. The experiment was carried out 10 times by looking at changes in the contents of the infusion fluid over time in 11 stages where the LED lights up when the weight of the infusion reaches 40 - 46 grams. Then, the buzzer and LED have turned on when the weight of the infusion is less than 5 grams. From the experiment, it can be concluded the 10% setpoint alarm works well, i.e. when the infusion load is less than the 1% set point, the buzzer and LED will light up until the intravenous fluid is replaced with a new one.
