Abstract

Intisari Photovoltaic Emulator merupakan alat yang dirancang untuk meniru karakteristik tegangan dan arus keluaran dari pembangkit listrik tenaga surya. Penelitian ini bertujuan untuk merancang dan mengimplementasikan Photovoltaic Emulator dengan menggunakan rangkaian elektronika daya dengan pemrograman pemodelan panel surya. Penyinaran mataharai dan suhu harian digantikan mikrokontroler dengan chip ATMega 328P sebagai komponen pengendali dan pemantau. Berdasarkan hasil pengujian, Photovoltaic Emulator yang dibuat dalam studi ini terbukti dapat meniru karakteristik tegangan dan arus keluaran dari panel surya dengan masukan irradiance dan suhu harian pada suatu daerah. Pengukuran menggunakan sensor arus dengan rata-rata galat senilai 2.601 persen dan sensor tegangan dengan rata-rata galat senilai 1,971 persen dibandingkan dengan pengukuran multimeter. Persentase kemiripan karakteristik keluaran Photovoltaic Emulator dengan panel surya yang ditiru yaitu 95.13 persen. Setiap data disimpan berdasarkan waktu pada secure digital card melalui datalogger. Kata kunci — Photovoltaic Emulator, Smart Grid, Embedded System. Abstract — Photovoltaic Emulator is a device designed for emulating voltage and current output characteristics of a solar panel. The purposes of this research are to design and to develop a Photovoltaic Emulator based on power electronic components and solar panel modeling software. The solar radiation as well as daily temperature were represented by a microcontroller with 328P ATMega chip as a controlling and monitoring component. From experiment results, the emulator is able to mimic voltage and current characteristics of the solar panel based on the irradiance and daily temperature in a certain area. The error measurement of the voltage and current sensor are 1.971 percents and 2.601 percents respectively compared to the multimeters. The similarity of Photovoltaic Emulator output characteristics with solar panels is 95.13 percents. Each data was stored based on time in the secure digital card through data logger.

Abstract

Intisari — Proses pemanenan buah tomat dapat dilakukan menggunakan metode visual dengan memperhatikan warna atau ukuran dari buah. Kemajuan teknologi menggunakan bantuan komputer membuat pemanenan dan pendeteksian kematangan buah tomat semakin mudah. Informasi kematangan buah tomat dapat diperoleh dengan cara pengolahan citra dengan bantuan fuzzy logic menggunakan metode Tsukamoto. Pada penelitian ini beberapa sampel buah tomat diambil nilai RGB melalui pengolahan citra sesuai dengan tingkat kematangannya, diantaranya mentah, setengah matang, dan buah matang. Setelah nilai RGB didapat maka akan diproses ke dalam fuzzy logic untuk mendapatkan informasi kematangan melalui aturan-aturan yang telah dibuat dan diintegrasikan menggunakan Raspberry Pi. Hasil penelitian ini menunjukan bahwa kondisi yang baik untuk melakukan pendeteksian buah tomat salah satunya yaitu pada kondisi indoor 100 Lux berlatar belakang gelap. Hal ini mungkin dikarenakan tidak terdapat pantulan cahaya berlebih sehingga citra yang diambil nilai RGBnya tidak terlalu tinggi dan mengurangi terjadinya kesalahan pembacaan informasi kematangan dalam proses fuzzy logic.Kata kunci — Image Processing, Fuzzy Logic, Modul Kamera Raspberry Pi.Abstract — The process of harvesting tomatoes is usually done by the visual method by looking at the color or the size of the fruit. Technological advancements by using computer assistance make harvesting and detecting the ripening process of tomatoes easier. The information of the process of Tomato’s ripening can be obtained by the image processing by using Tsukamoto Fuzzy-Logic. In this research some samples of tomatoes’ RGB values were taken through image processing in accordance with the ripening level, between unripe, under-ripe, and ripe fruit. After the RGB value is obtained, it will be processed into fuzzy logic to obtain the ripening level information through rules that have been created and integrated by using Raspberry-Pi. The result of this research indicates that a good condition for detecting tomatoes is in 100 Lux conditions with dark background. This might be because there is no excessive light reflection, so that the RGB value of the image is not too high and reduces the error of reading the ripening level in the fuzzy logic process.Keywords—  Image Processing, Fuzzy Logic, Raspberry Pi Camera Module.

Abstract

Abstract Electricity consumption in Metro City has increased along with the increase in population, economic activity, technological progress and growth of households. Electrical energy is needed for the interests of industry, households and other activities as well as to support increasingly advanced technological developments The researcher used load forecasting with a combined method based on economic growth, population growth, and the growth of households in Metro City. The data used in this study are growth data that occurred from 2014 to 2018. The results of this paper is forecasting the number of customers, load energy consumption (MWh), total energy requirements (MWh), connected power (kVA), and peak load (MW). Energy consumption growth every year has the same tendency as in previous years. In the household sector, energy consumption will grow higher each year than other sectors. In 2029, it estimated that the peak load that will occur at Metro substations, PT PLN (Persero) Rayon Metro City is 92.62 MW.

Drying clothes is one of daily life activities. Drying clothes is usually left open in the field using clothesline, so that there is not enough suitable time to carry the clothes when rain fall from the sky. This can be a problem, so that in this study, we propose a device that can inform the condition during the rain. This rainwater detection device is created by using a PCB conductor board as a rainwater sensor, the DC motor whose function is to close and open the clothesline, the Arduino Uno microcontroller which is used as the main controller of this device and the wavecome modem that is used to send SMS notifications when the rain come. This rainwater detection device can work as expected.
