Abstract

An injury is a disorder that occurs in the body which results in the appearance of redness, pain, swelling and the inability to function properly in the limbs. Handling of minor to severe injuries is carried out with medical treatment such as surgery or traditional medicine, but this treatment has not provided any assurance of healing, as for the alternative treatment, namely heat therapy. Heat therapy is able to open blood vessels wider and can provide a supply of oxygen and nutrients to reduce pain in injured sufferers. From this research, it can be produced a design of an electric therapy device that can produce heat equipped with a heat setting and a therapy time controller. The design of an electric therapy device to help heal physiotherapy dipole injuries at Dr. SOEDOMO Trenggalek Hospital has several advantages, namely that it can generate heat according to temperature settings, can adjust the length of therapy process time according to time settings and can also provide a display of temperature and time on the LCD display. The results of research on this electric therapy device are able to work according to predetermined working principles.

Abstract

E-learning is currently very important and a must for educational institutions. Many e-learning application platforms are based on Learning Management System (LMS) that can be used by schools, whether they are open source, paid for or build their own applications. There are many considerations that must be faced when deciding to use an e-learning-based application (LMS) including infrastructure readiness, costs and application compatibility with the e-learning concept desired by educational institutions. The availability of features in the e-learning system is one that must be adjusted to the e- learning concept that will be selected. Each institution may be able to determine its own characteristics that can be specific and not yet fully accommodated in the e-learning application that currently exists. One of them is the feature to randomize exam questions to ensure that each student gets different questions with the same composition. This research will try to answer this problem by integrating the fisher-yates shuffel algorithm. The success of this algorithm integration will be assessed by conducting an exam simulation involving two classes and seeing how the system will randomly divide the exam questions to each student. The first assessment is the suitability of the composition of the questions and the similarity of the questions between students, the less students receive the same questions appearing on the exam questions, the better the system performance.

Abstract

As technology develops in the automotive world, more and more motor vehicle manufacturers are also applying the latest technologies, especially for vehicles sold in general. Call it, for example, the development of the fuel system, which was still a carburetor, now uses an injection system, from S.O.H.C to D.O.H.C. these technologies are useful for increasing volumetric efficiency. In this study, the researchers wanted to increase the volumetric efficiency of the Astro 108 cc engine by applying a simple modification, namely the inlet and exhaust that was modified with a 30 backcut on the valve, undercut system, and 4 angle valve jobs (30 , 45, 60 , 75 ). By applying these modifications to the Astro 108 cc engine, it can increase its volumetric efficiency, say at 2300 rpm with standard inlet and exhaust conditions producing an air flow rate of 0.000358 m3 / s and 0.000814 m3 / s, this data is obtained from pressure taking on the water box meter. The difference in flow occurs because the air that enters the inlet and exhaust is smoother due to the modifications made. With this flow rate, at 2300 rpm standard head produces a volumetric efficiency of 19.05712%, and 43.26364% with a modified head.

Abstract

MTs Darul Fikri Bringin is a Tsanawiyah Madrasah located in Ponorogo. This madrasah has a good learning system to support the quality of madrasah, one of which is a superior class program. MTs Darul Fikri Bringin is always experiencing an increase in the acceptance of new student registrants every year. In determining the superior class, there are difficulties in class clustering based on students' abilities. This is due to the increasing number of registrants each year. Therefore, in this study the data mining method is applied to help cluster superior classes with student grade variables using the K-Means Clustering Algorithm and Rstudio Tools. Where the attributes used are the report card value, activeness and presence of class VII students. The K-Means Clustring Algorithm method is used to process these 12 attributes so as to produce 2 regular clusters and 1 superior cluster with the Rshiny interface in Rstudio using the R programming language. A in cluster 1 has 23 members. Classes B, C, D include regular classes which include class B in cluster 2 totaling 25 members and classes C and D in cluster 3 totaling 52 members. The application of the K-Means Clustering Algorithm and Rstudio Tools can cluster the determination and selection of superior classes at MTs Darul Fikri.

Abstract

Geographical information system is a system that combines elements on a map that is prepared to process data, analyze, and display spatial data to improve design. In the era of technology, information and communication (ICT) for organizations, agencies and public services is very important and needs to be implemented immediately. ATR / BPN in Jonggol village, Jabon, Ponorogo, still uses the manual method in processing certified land registration. The process of seeking, processing, and collecting certificate data requires a lot of time, causing services to be inefficient and effective and community satisfaction also decreasing. Therefore, a technology is needed that can facilitate service officers to search for certified land ownership data by implementing the brute force algorithm in the Geographical Information System for certified land ownership. The application of Algortima Brute Force in this geographic information system can run well, but if the text characters are long inputted, the system search process will take longer (if the text is short, the search can run quickly). On 10 keywords with different keyword or character lengths, the average search time was 0.06335 seconds.

Abstract

Television is an electronic device which now the majority is owned by all Indonesians. Besides the use of this electronic device, there is a negative impact or thing that is contained in this electronic device. When watching television, eyes often experience tired and dry eyes, this is caused by television monitors that emit radiation rays and cause several eye problems. The radiation beam emitted from each television differs depending on the size of the monitor. This has been proven by tests that have been carried out by related institutions that the distance to watch television for each monitor is different. "The eye has the most important role for the development of human intelligence". Therefore a tool was designed from the problems that arise which will set the ideal distance for watching television using the PIR sensor to determine the distance of the audience from the television which will be forwarded to Arduino UNO as data processing, the output of the tool is in the form of LED, Buzzer and executed by Rellay as Automatic shutdown where the television will be turned off automatically when the audience enters a distance of less than 3 meters and within 1 minute with the LCD indicator displaying text data in the form of "Danger" and the television will not be turned off automatically if the viewing distance is more than 3 meters and the LCD will display text data in the form of "SAFE".
