Abstract

The use of cooking oil repeatedly and beyond the normal limits (waste cooking oil) can cause variety of dangerous diseases to human health such as heart failure, high risk of diabetes, coronary heart disease, and others. However, the use of waste cooking oil is still high today. This is shown from the results of research in Makassar which is poor and rich people use the same cooking oil for frying as much as 61.2 percent use it twice, 19.6 percent use it three times, and 5.4 percent use it as four time. Based on the problem, it is necessary to have an automation system for classifying the frequency of the using cooking oil, so it can be used for the frequency classification of the use of cooking oil that has been used several times (waste cooking oil) accurately. In this study, the parameters used are the color and turbidity level of cooking oil. Determination of cooking oil classification is based on color and turbidity level of oil obtained from TCS3200 color sensor readings and sensor photodiode by Arduino Uno microcontroller by using Bayes methods. This method is chosen because it is one of the classification method that is quite simple, easy to understand, and has high computing speed. From the results of the tests performed, it is known the percentage error reading TCS3200 color sensor is 1.9% and photodiode sensor can work well. So, if the cooking oil is more turbid, the value of the photodiode sensor is smaller. Furthermore, the test system using Bayes methods with the amount of training data is 65 data and test data is 35 data obtained an accuracy of 71.42% with a system of computing time on average over 13.144 seconds.

Abstract

The development of robotics world is quite rapid, many robots are created not only to petrify human jobs, even robots deliberately created to replace the role of humans in their daily life. Various types of robots have been created, one of them is humanoid robot types that resembling a human body shapes. The development of humanoid robot in Indonesia is not less rapid with other countries. In the development, walking technique is a major factor in making humanoid robot. Humanoid robots are required to have the ability to walk like a human by balancing the body position when walking so as not to fall. So that required tilt position detection system robot and balancing system when the robot will fall. So to overcome these problems, this study was conducted. Research by implementing complementary filter method on gyroscope and accelerometer sensors to minimize noise or disturbance of sensor output value. So the accuracy of MPU6050 sensor output value at the angle position detector can assist the robot in giving the balancing action. Testing this research is divided into four parts, among others: testing unfiltered sensors, testing alpha value changes on the method, testing robot reaction to input sensor values ​​in realtime and manual. According to the testing, the best alpha is 0.96 with a sampling time of 0.04 seconds. Robot reaction testing of real-time sensor values ​​fails in robot balancing act, because CM-510 is delayed in moving the servo to provide counterbalance motion and can not keep pace with the data processing speed of Raspberry pi 3 B against sensor data with 40 ms sampling time. As for testing robot motion reaction manually with testing gives disturbance from the front, rear, right and left robots can get a balancing reaction in accordance with the expected.

Abstract

A design system is a fundamental phase of system development. Department of Animal Husbandry and Animal Health Malang Regency is one of the government agencies are a source of information that covers all areas of the animal husbandry. Production department is one important area that has information about the development of livestock, feed and cultivation in poor districts. Event reporting to be one of the core activities in this department. Often a confusion in the reporting data and inefficiencies of time having to do a recap of the data twice. Sharing data is also often a constraint resulting in less up to date information. Given an SOA-based system, it can maximize the activity of reporting in this production field. Thus study was conducted to analyze the requirements, designing the system, ensure consistency, and ensure it meets several criteria SOA. This study begins with data collection process using observation, interview, and literature study to obtain preliminary data of the user's needs. The next step is to do an analysis and design using Ripple methodology to produce requirements definition and artifacts design, then do the testing process design by using Consistency Analysis to determine the consistency of the design and the Service Litmus Test to determine if the design had to meet several criteria SOA. Testing consistency defining requirements will result in a value of RCI (Requirement Consistency Index) and satisfies the equation on business alignment and reusable on a litmus test. Requirement analysis generates use case as the definition of the functional system requirements and supplementary requirements as the definition of non-functional system requirements. Designing the system generates artifact design, include: user interface sketch, communication diagram, class diagram, sequence diagram, and database schema Testing consistency defining requirements resulted in RCI value of 100%, which means defining the needs of the system is 100% consistent. Testing litmus test resulted in the design meets the business alignment and meets the criteria reusable.
