<p class="Abstract">Industrial sterilization is a very important problem. Ozone is a powerful oxidizer that can function for sterilization and is environmentally friendly. Plasma DBD (Dielectric Barrier Discharge) is one of the effective technologies to obtain ozone. The ozone generator currently uses a lot of manual control operations. Manual control uses a mechanical system in the form of a potentiometer to calibrate the frequency and output of the ozone generator output, so that digitization and automation are needed to operate to replace human labor. The design of the digital ozone control generator is done using an AVR microcontroller. Programming used in this research is basic language (BASCOM), then uses a DAC (Digital to Analog Converter) system which is the output of a Microcontroller with a Weighted Binnary Resistor. The output of the microcontroller is frequency and 8 bit digital with a decimal parameter of 200. The result of automation is that the timer works for 2 hours. The greater frequency the ozone produced. At a frequency of 1500Hz the power produced is 308.58 watts with an ozone concentration of 59 ppm. Efficiency using a switching system&gt; 90%.</p><p>                                                                                                                                                                                                  </p><p class="IndexTerms"><strong>Keywords</strong>: Plasma, AVR Microcontroller, Ozone.</p>

<p>The need for water is very important for the production process, the water quality must also be considered the pH value so that the water is suitable for use in boilers or chillers. Seeing from these needs a simulation was made on matlab R2017a using a fuzzy toolbox that can find out the water quality with fuzzy mamdani method. This fuzzy logic simulation can determine the standard value of boiler water pH (10.5-11.5) and the standard pH value of chiller water (6-8) in the production machine. The methods in fuzzy logic used are mamdani and centroid methods as deffuzification with R2017a matlab simulation tool. The fuzzy inference system used is the mamdani method.

<p>An incubator is a place designed to maintain a certain temperature condition. Incubators are often found in hospitals and farms. In hospitals, the Incubator functions to warm newborns, or premature babies. On farms, this incubator is usually used for egg hatchers and as a place for newly hatched chicks. Incubators are usually in the form of a room or box (box) of a certain size. In this research will be designed a prototype to modify the infant incubator by adding sensors to regulate the temperature and control using a Arduino microcontroller. This incubator has a measurement system and temperature regulation using LM35 sensors, heaters and fans as actuators that can cool the incubator room with Arduino as controlling. Temperature setting will be monitored by LABVIEW. In the Arduino system a program can be set up that can adjust the temperature . The temperature required by the premature baby, so that it can maintain the stability of the temperature. If the temperature in the incubator is smaller than the temperature setting, the heater will turn on and the fan speed will decrease to increase the temperature according to the settings entered. If the temperature in the incubator is greater than the temperature setting entered, the heater will turn off. The results showed that the linear regression value between the temperature values with the ADC value of y = 0.4883x with a determination coefficient of 1, while the linear regression value between the temperature with a voltage value of y = 99.481x with a coefficient of 0.9984.<br />Keywords: Infant Incubator, temperature sensor, LM35.</p>

Salah satu asas yang ada dalam hukum perjanjian adalah Asas Kebebasan Berkontrak. Berdasarkan asas ini, para pihak diberikan kebebasan  untuk menentukan isi, bentuk dan dengan siapa akan mengadakan perjanjian. Realisasi asas ini  nampak dalam Perjanjian Baku (standaard contract), yakni perjanjian yang  isi atau klausulanya sudah dibakukan oleh salah satu pihak sehingga pihak lainnya tidak ikut menentukan substansi perjanjian. Dalam Perjanjian Baku dikenal adanya konsep take it or leave it . Dikaitkan dengan asas kebebasan berkontrak, dalam Perjanjian Baku masih dimungkinkan adaya kebebasan berkotrak karena pihak yang tidak membuat perjanjian diberikan kebebasan untuk menerima perjanjian dilambangkan dengan ”take” atau menolak perjanjian dilambangkan dengan “leave”. Dengan demikian perjanjian baku yang mengenal take it or leave it telah sesuai dengan asas kebebasan berkontrak dalam aspek formil karena tidak terdapat adanya paksaan untuk mengikatkan diri dalam perjanjian.
One of the basic principles of the legal contract is the freedom of contract. According to this principle, freedom is given to determine the content, form, and to whom the contract is made. The realization of this principle appears in the standard contract, known as an agreement in which the content has been standardized. So the parties could choose to take it or leave it. Furthermore, there might be freedom of contract in standardize contracts because those who disagree are given the freedom to accept the agreement (“take”) or reject the agreement (“leave”). Eventually, the standard contract of “take it” or “leave it” is already suitable with the principle of freedom contract in the formal aspect because there is no pressure to commit in the contract.
