The equipment of automatic pH control system has been introduced on the hydroponic with microcontroller ATmega328p. The aim of this research is to create a pH control system to reins water pH on hydroponic. This control system consists of hardware such as pH sensor, microcontroller Atmega328p, servo motor, water pump, LCD and software such as program algorithm. Hardware components were control by program algorithm. The pH value of hydroponic was monitored by pH sensor. The pH value has been read by the sensor used to servo control on taps the acid and alkaline shelter. The pH control uses range of 5.50 to 6.50 as set point. The results showed that pH sensor has the calibration average error of 2.28%. The pH control system showed servo 2 "ON" and servo 1 "OFF" when pH value < 5.50. This resulted that addition of an alkaline that increasing pH of the liquid. And than servo 1 and servo 2 "OFF" when pH value on 5.50 to 6.50. This shows that the pH of the liquid on set point condition. While the servo 1 "on" and servo 2 "OFF" when pH value > 6.50 which resulted the addition of acid liquid that resulting decrease on pH of the liquid.

A thermoelectric cooler (TEC ) is a component of an electric solid-state cooler that works as a heat pump in the cooling process. Utilizing the peltier effect that is when an electric current is flowed heat absorption occurs on both sides of the thermoelectric and the release of heat on the other side. The use of thermoelectric as a coolant in cool box systems has been widely studied. The purpose of this study was to determine the performance of the cooler using thermoelectric based on the circuit and air velocity in the wind tunnel. The studied performance includes temperature difference, heat absorption, and coefficient of performance. The method used in this study is a real experimental method, with research variables namely series and parallel thermoelectric series and wind tunnel air velocity. Data were taken in the form of cool room temperature cold side temperature, hot side temperature, heatsink temperature, and ambient temperature. Thermoelectric connectivity electrically uses series and parallel circuits and is thermally arranged in series. The results showed that the thermoelectric circuit and wind tunnel air velocity affect the performance of the thermoelectric. Thermoelectric with series circuit produces the highest COP absorption compared to the parallel circuit. The highest performance thermoelectric series is obtained at an airspeed of 9.8 m/s. in these conditions the temperature difference (AT) produced reaches 19oC. the heat absorption (qc) reaches 34.26 watts and the COP reaches 0.89

Abstrak— Pada penelitian ini dihasilkan perancangan dan sistem pendingin ruangan, hasil pengujian akurasi (thermoelektrik cooler, dan hygrometer). Pada hasil pengujian thermoelektrik cooler hasil rata-rata peltier didapatkan suhu 8,5 oC, peltier kedua didapatkan rata-rata 8,6 oC, peltier ketiga didapatkan rata-rata 5 oC, peltier ke empat didapatkan rata-rata 4,8 oC, peltier kelima didpatkan rata-rata 4,6 oC, dan peltier terakhir didapatkan 4,1 oC. Dan untuk hasil pengujian menggunakan hygrometer pembacaan temperatur relatif antara sensor NTC dengan hygrometer linear dengan R2 0,8004, dimana R2 merupakan regresi dan dapat menunjukkan kelelitian pengukuran alat yang dibuat sebesar 80 %. Dari data-data yang telah dianalisa, secara umum sistem suhu pendingin ruangan styrofom menggunakan thermoelektrik cooler pada penelitian ini telah memenuhi syarat umum sebuah pengendali, dimana untuk variasi-variasi akan menghasilkan respon yang diinginkan dari sebauah sistem pendingin. Apabila ada gangguan dari luar dapat ditanggapi secara responsif dari sistem, dengan selalu berusaha mendekatkan suhu sesuai set point.
