Penyimpanan biji kacang tanah tanpa kulit ari di toko grosiran sudah memanfaatkan teknologi pengemasan vakum. Akan tetapi pada pengencer pasar atau toko kecil masih menggunakan metode konvensional. Penyimpanan secara konvensional menyebabkan tidak terjaganya mutu biji kacang tanah yang disimpan oleh pengencer pasar. Salah satu cara untuk mengatasinya adalah dengan menerapkan pengemasan vakum. Penelitian  ini bertujuan untuk merancang dan membuat sebuah alat vakum kemasan menggunakan mikrokontroler ATMega328P sebagai kendali alat tersebut. Alat ini dirancang untuk melakukan pemvakuman yang disertai dengan penyegelan kemasan menggunakan sealer. Apabila mikrokontroler menerima sinyal dari sensor infrared yang mendeteksi keberadaan kemasan di atas tatakan, maka button berfungsi sebagai tombol start. Dengan menekan button maka alat akan mengeluaran udara di dalam kemasan menggunakan motor DC yang setelahnya diiringi dengan penyegelan kemasan kacang sehingga dihasilkanlah pengemasan kacang secara vakum. Berdasarkan uji coba yang telah dilakukan, alat ini membutuhkan daya sebesar 7 Watt dengan durasi pengoperasian selama 22,21 sekon. Alat ini juga mampu mengeluarkan udara di dalam kemasan. Jadi disimpulkan bahwa alat ini bekerja dengan baik.

Tomatoes plant is one of a plant that has a promised business opportunity, especially in Indonesia. The quality and output from tomatoes plant can be improved by paying attention to soil moisture and temperature of the plant, those things can be recked by watering the plant. Normally people do plant watering manually, that way was less effective because of water debit was not match to its need. Therefore smart automatic watering tomatoes plant and monitoring using internet will be needed, so quality and output can be improved, also farmer duty can be a lot easier. This device consists of DHT22 and soil moisture sensor as measures indicator of plant temperature and soil moisture, NodeMCU as connector between arduino and internet, 12V DC pump for watering tool, relay as contact for controlling the pump, and arduino as the main system to run the watering that going starts when the moisture level below 60% and stop at 75%. Arduino is used to receive data from sensors and send it to nodeMCU that connected to the internet, so user can monitor tomatoes plant via internet.

Perkembangan teknologi dan sistem kontrol sangat cepat berkembang dan peralatan elektronik telah menjadi bagian yang tidak dapat dipisahkan dalam kehidupan sehari. Salah satunya motor DC  sebagai pengerak. Dalam pengontroloan motor DC, keluaran dari tegangan searah (DC) tersebut dapat dirubah menjadi lebih besar atau lebih kecil. Pengaturan kecepatan putar motor DC dilakukan dengan  memvariasi duty cycle menggunakan potensio pada rangkaian buck converter. Berdasarkan hasil pengujian didapatkan bahwa alat dapat berkerja sesuai dengan karakteristik DC-DC converter tipe buck converter dengan hubungan antara duty cycle dengan tegangan keluaran berbanding lurus, semakin besar nilai duty cycle, maka semakin besar pula nilai tegangan keluaran. Dengan hasil pengukuran buck converter dengan duty cycle 63,3% yang menghasilkan tegangan keluaran 50 volt, arus keluaran 0.27 amper dan kecepatan putar motor 400 rpm.
Kendali Kecepatan Motor DC Dengan Kontroller PID dan Antarmuka Visual Basic

Kecepatan motor DC sering mengalami penurunan akibat dari beban yang ada, sehingga kecepatanya menjadi tidak konstan sehingga diperlukan rancangan kontroller.  Dalam artikel ini, mengimplementasikan suatu alat pengendali kecepatan motor DC dengan kontroller PID dan antarmuka visual basic berbasis Arduino UNO. Pada alat ini setpoint dan parameter PID diinputkan melalui visual basic. Sensor encoder akan membaca kecepatan motor dan kontroller PID akan membandingkan nilai yang terbaca dengan setpoint dan selisih tersebut dinamakan error. Nilai error akan dimasukan ke persamaan PID dan keluaran dari PID berupa PWM(pulse width modulation) yang menjadi masukan untuk driver motor L298N melalui mikrokontroller Arduino UNO. Selanjutnya terjadi pengulangan proses sampai mencapai nilai setpoint yang ditentukan dan kecepatan akan dipertahankan. Penentuan hasil parameter kontroller PID ini didapatkan dengan penalaan trial and error. Trial and error dilakukan dengan cara meinputkan nilai Kp, Ki, Kd dan melihat kurva respon sistem sampai didapatkan bentuk kurva respon yang diinginkan. Dengan menerapkan kontroller PID kecepatan putaran motor DC dapat tercapai dan stabil sesuai dengan nilai setpoint yang ditetapkan.
