<![CDATA[Garbage is an object or material that is no longer used by humans so that it is thrown away. Community activities that produce waste are not only the responsibility of the government, but the community must also be responsible for processing waste so that it does not have a negative impact on the surrounding environment. Garbage is one of the problems that must be considered, because waste from year to year continues to increase along with the increase in population. In order not to cause environmental pollution, waste must be processed according to the type of waste so that it is beneficial for people's lives and health. Therefore, waste must be sorted according to the type of waste to facilitate the recycling process. For the waste sorting process, it is still done conventionally, and manually, namely sorting using different methods of garbage bins based on the type of waste and sorting manually, using staff. Waste sorting that previously used the manual method was replaced with an automatic sorting system. This waste sorting system starts from the input process that comes from the proximity sensor, loadcell sensor, and ultrasonic sensor. This system uses Arduino Mega as a micro controller that functions as a data processing center in the sorting system. The results obtained are that the proximity sensor can detect the type of waste and send data to the Arduino to determine where the servo motor will move to move the garbage according to its type. The weight of the garbage in the container is measured with a loadcell sensor to detect how much garbage weighs. Ultrasonic sensors can measure the amount of waste in the container. Users can see the status of the container on the LCD attached to this tool. ]]>

<![CDATA[NiTi alloy is a highly functional alloy of Ni (nickel) metal and Ti (titanium) metal used for engineering. This NiTi alloy has good biocompatibility properties against human body tissues so that currently it is widely used for medical devices. This study aims to determine the effect of temperature on the tensile strength of NiTi Nanopillars and to investigate the behavior of the atoms making up NiTi nanopillars due to tensile loading. From the results obtained, the authors found the greatest value of the modulus of elasticity for the NiTi Nanopillar alloy with a temperature of 100 K, which is 80.4321 GPa. Meanwhile, the lowest modulus of elasticity is the NiTi Nanopillar alloy with a temperature of 600 K, which is 65.5847 GPa. So it can be concluded that the greater the effect of temperature on the NiTi Nanopillar alloy, the smaller the modulus of elasticity will be. This thesis also discusses the stress-strain and mechanical properties of NiTi Nanopillar alloys during the simulation process. ]]>

<![CDATA[Currently, the world of education must be managed professionally, because of the increasingly fierce competition in education today. Educational institutions will be abandoned by the community if they are managed poorly. MA Muhammadiyah 1 Ponorogo School is one of the private schools owned by the Muhammadiyah business charity in Ponorogo district. MA Muhammadiyah 1 Ponorogo has a small number of students, due to the lack of student interest in entering the school. To find out that students are interested in entering MA Muhammadyah 1 Ponorogo, the school made a new breakthrough that could attract students to register there. To find out, the researchers used data mining techniques with the Apriori Algorithm method, and supported by the Apriori web browser system by examining student extracurricular interest data with 177 respondents with 47 extracurriculars. Data Mining is a combination of data analysis techniques, while Apriori Algorithm is a method which is most often used because it is very simple, easy and the most widely proposed by several researchers, because there are two parameters, namely Support and Confidence. So the results of the” research predictions obtained are that the most popular extracurriculars for junior high school/MTs students are futsal and volleyball with a minimum value of support = 11% and a minimum value of confidence = 52%. ]]>
