Abstract

ABSTRACT The green revolution in the field of palm oil farming not only contributes to processed products but also produces large-capacity waste originating from its processing starting from the sterilization process, water from the clarification process, hydro cyclone (clay bath) water, and factory washing water. Palm oil mill effluent (LCPKS) contains dissolved and suspended solids in the form of colloids and oil residues with high BOD and COD. If this liquid waste is discharged directly into the water, it can pollute the environment. Some will settle, decompose slowly, consume dissolved dcxdcoxygen, cause turbidity, emit a sharp odor and can damage the aquatic ecosystem. To improve the parameters in the LCPKS so that it is feasible to flow to water bodies or the environment, an LCPKS treatment experiment test is performed by applying corona discharge with variations in voltage and length of time, then comparing the effect on parameters such as BOD, COD, pH and TDS on LCPKS before treatment and after treatment. From the treatment process using a corona discharge application with variations in voltage and time able to reduce BOD levels up to 35%, COD 36%, increase in TDS reached 71.56% and decreased pH by 4.11%.Key words: Palm oil mill effluent (LCPKS), Corona discharge application (Corona Discharge Treatment), COD, BOD, TDS, pH

Abstract

AbstractLoad flow analysis is a study to plan and determine the amount of power in an electric power system. During its development, industry requires a large amount of electric power and uses electrical equipment as a means of production. The benefits of an electric load flow analysis are to find out the amount of power in the electric power system whether it still meets predetermined limits, and to find out the amount of voltage at each point, and to obtain initial conditions for the new system planning. Load flow analysis begins calculating the active power and reactive power at each node (bus) installed, loading on the channel or conductor, the load flow calculation will be assisted using the Julia program. From the results of calculations using the Julia program, the voltage at each point with the smallest stress is obtained, namely the 10th point of 209.89 - j10.34V for phase A, -107.39 - j186.87V for phase B, -108.12 + j178,51V for phase CKey Words: Drop Voltage, Julia, Load Flow

Abstract

In general, the control of using electronic equipment in the classroom manually. Sometimes lecturers or students forget to turn off electronic equipment after the class so that there is a waste of electrical energy use. Application of automation of using electronic equipment is one solution to overcome these problems so that electrical energy becomes more efficient. This study designed a prototype of an automation system for electrical equipment in the classroom, namely lights, fans, and projectors. This system was also to turn off the electricity when nobody was in the class. The automation system controls the use of electrical energy in devices in the classroom through on-off control of the electrical network components connected to each device. In this design, the PIR sensor can detect the presence of people up to a distance of 7 meters. The Arduino Uno controller activates the lights in the class when the LDR Sensor detects a light intensity of less than 200 Lux. Then, the fan is active when the LM35 sensor detects the temperature in the class above 28oC. The FC-04 sensor detects the sound of clapping for control of projector ignition by the controller.

Abstract

Selain sebagai bahan bakar kompor gas, Liquefied Petroleum Gas (LPG)  dapat dimanfaatkan sebagai bahan bakar genset. Untuk kemudahan penyalaan genset yang menggunakan LPG, diperlukan campuran LPG dan udara yang tepat. Tujuan penelitian ini yakni menganalisis pengaruh campuran LPG dan udara terhadap kemudahan penyalaan awal genset 4 langkah.  Metode yang digunakan dalam penelitian ini adalah metode eksperimen, yaitu menguji pengaruh variasi laju aliran gas LPG  dan  pengaruh variasi  bukaan katup saluran udara. Laju aliran LPG yang digunakan yakni 2 L/min, 3 L/min, 4 L/min. Udara yang masuk keruang bakar divariasikan dengan pengaturan bukaan katup yakni katup terbuka penuh, terbuka setengah dan tertutup rapat.  Hasil penelitian menunjukkan bahwa campuran yang paling tepat untuk kemudahan penyalaan awal genset yaitu pada variasi dengan laju aliran 3 L/min pada posisi katup ditutup rapat.  Saat katup ditutup rapat sebenarnya masih terdapat celah lobang udara pada choke dengan diameter 6 mm standart bawaan karburator. Udara yang dihasilkan dari lubang ini ternyata cukup efektif  saat dicampur LPG dengan laju aliran gas 3 L/min. Dengan demikian dapat disimpulkan bahwa genset LPG mudah dinyalakan jika campuran LPG dan udara tepat.
