Abstract

The influence of connected electrical load will cause significant problems on Solar Electric Power Generator (SEPG). The problems are extremely important to be identification in order to provide electrical energy optimally. The objective of this paper is tantamount to investigate the impact of household electrical load on SEPG with variation and continuous electrical load. The identification of power quality was made by marking several test point on each output of SEPG unit. The level quality of voltage and frequency system needed to be measured and observed its performance indicator level. Furthermore, it compared by existing standard. To variation electrical load test, the results showed that the frequency of the system changed from 52 Hz to 262 Hz. In other hands, the frequency rose about five times against normal frequency. The continuous load test, that frequency of system fluctuated around 52 Hz to 156 Hz that also showed abnormal operation of SEPG.

Abstract

The problem of forest and peatland fires in Riau has become main topic to prioritize its revamping. Land and forest fires in Riau until reached 3,700 hectares area, happened in some last years,.Forest and peatland fires occured in the majority of districts in Riau Province, from low category of 4 hectares until 2,800 hectares. This researchdiscusses aboutanalysis of controlling wirelessTemperature Sensor for monitoring Peat-Land fire by using LM35 Temperature Sensor, Transmitter-Module (HC-12), Receiver-Module (HC-12), Arduino-ProMini to produce outputs on LED, LCD, Buzzer. Detector of Peat-Land fire works when it is burning, so heat will spread through aluminium stalk and be read by Temperature-Sensor1 upto Temperature-Sensor4. Output of each sensor is sent to each control block of Arduino-ProMini in Transmitter-Module(FU1–FU4). From Arduino-ProMini, it is sent toReceiver-Module(FU5). Receiver-Module only receives one data from Transmitter-Module in one time. Every data is received by Receiver-Module goes to Arduino-ProMini, processed to produce outputs on LCD that shows ID of FU1–FU4, Peat-Land Status, temperature of Peat Land. If LED is Green, Peat-Land not burned, LED shows SAFE Condition, Buzzer Off. If LED is Yellow, Peat-Land burned underground, LED shows BE-CAREFUL Condition, Buzzer On. If LED is Red, Peat-Land burned on the ground, LED shows DANGER Condition, Buzzer On. Temperature 0°C–21.9°Cis SAFE Category because Peat-Land not burned. Temperature 22°C–28.4°Cis BE-CAREFUL Category because Peat-Land burned underground. Temperature 28.4°C–50°Cis DANGER Category because Peat-Land burned on the ground. This equipment works as its frame work.

Abstract

Rice is the staple food of the Indonesian people. Rice is produced through a lenghty process. One crucial stage of the post-harvest process is the drying of rice. The decline in rice production occurs at this drying stage. This research designs a tool that can dry rice automatically in order to facilitate the drying process of rice grain. This tool uses a DHT22 sensor as a temperature and humidity detection sensor. The Power Window motor is used as a driver of the rice  rain stirring shaft that is being dried, while the Blower and Heater as a heater. This tool is equipped with NodeMCU as a microcontroller to send signals to the Telegram application on a smartphone so that status notifications on the LCD of this tool can be seen through a long distance. Testing of this tool is carried out on rice weighing 5 kg and 10 kg with a test time of 3 consecutive days. Drying is done in the morning and afternoon.  Rice drying tests in the morning for 5 kg of grain are 32 minutes, 41 minutes, and 45 minutes, then 45 minutes, 55 minutes and 55 minutes for 10 kg of grain.  In the afternoon, 27 minutes, 25 minutes and 29 minutes for 5 kg of grain, and 42 minutes, 38 minutes and 36 minutes for 10 kg of grain. The average grain shrinkage during the drying process in the test period was 7,5 percent for 5 kg of grain and 7,7 percent for 10 kg of grain ABSTRAK; Beras merupakan makanan pokok masyarakat Indonesia. Beras dihasilkan dengan proses yang panjang. Tahapan proses pasca panen yang sangat penting adalah pengeringan gabah padi. Penurunan produksi beras banyak terjadi pada tahapan pengeringan ini. Penelitian ini merancang alat yang dapat mengeringkan padi secara otomatis agar dapat mempermudah proses pengeringan terhadap gabah padi. Alat ini menggunakan Sensor DHT22 sebagai sensor pendeteksi suhu dan kelembaban. Motor Power Window digunakan untuk penggerak poros pengaduk gabah padi yang sedang dikeringkan, sedangkan Blower dan Heater sebagai pemanas. Alat ini dilengkapi dengan NodeMCU sebagai mikrokontroller untuk mengirim sinyal ke aplikasi Telegram pada smartphone sehingga notifikasi status pada LCD alat ini bisa dilihat melalui jarak yang jauh. Pengujian alat ini dilakukan pada padi seberat 5 kg dan 10 kg dengan  lama waktu pengujian 3 hari berturut-turut. Pengeringan dilakukan pada saat pagi dan siang hari.  Pengujian pengeringan padi pagi hari untuk 5 kg gabah yaitu 32 menit, 41 menit, dan 45 menit,  kemudian 45 menit, 55 menit dan 55 menit untuk gabah 10 kg.  Pada siang hari yaitu 27 menit,25 menit dan 29 menit untuk gabah 5 kg, dan 42 menit, 38 menit dan 36 menit untuk gabah 10 kg. Penyusutan gabah rata-rata selama proses pengeringan dalam periode pengujian alat, yaitu sebesar 7,5 persen untuk gabah seberat 5 Kg dan 7,7 persen untuk gabah seberat 10 Kg.

Abstract

Masalah energi telah menjadi isu global dalam tiga dekade terakhir. Masyarakat dunia sangat kuatir dengan peningkatan kebutuhan energi terutama fosil, namun cadangannya semakin menipis. Konstribusi sumber energi fosil tidak dapat diharapkan lagi dalam memenuhi kebutuhan energi dunia dalam jangka panjang. Ketergantungan terhadap sumber energi fosil harus dicarikan penggantinya dengan memanfaatkan sumber energi lain. Permasalahan dibidang energi tidak hanya menyangkut sumber energinya saja, namun teknologi pengolahan sumber energi juga sangat memerlukan invensi dan inovasi teknologi. Masyarakat harus mendapatkan edukasi yang cukup dalam menghadapi krisis energi ini dalam berbagai bentuk penyuluhan dan pelatihan. Materi penyuluhan mencakup bagaimana proses biomassa menjadi bioenergi dan biofuel. Biomassa yang sudah tidak berguna dapat diolah menjadi energi agar bermanfaat bagi kehidupan. Penyuluhan ini menyampaikan permasalahan energi dan teknologi energi di masa depan. Penyuluhan ini disampaikan kepada generasi muda yang masih usia sekolah karena ditangan merekalah digantungkan harapan untuk mengatasi krisis energi di masa yang akan datang. Siswa-siswi SMUN 1 Pasir Pangaraian sangat antusias mengikuti penyuluhan teknologi konversi energi ini. Harapannya setelah mendapatkan penyuluhan ini, peserta menjadi manusia yang sadar energi sehingga mereka mampu berhemat energi dan mampu memecahkan permasalahan energi sesuai dengan usia mereka.
