Abstract

Limitations of someone's ability to communicate in public places become an obstacle for everyone. A student, especially a campus ambassador is required to have good communication ability, therefore the information conveyed can be received by all parties. To overcome the problems faced by prospective campus ambassadors, in this article an activity is proposed in the form of public speaking training for Campus Ambassador nominees at the Cilacap State Polytechnic. The training is carried out using the lecture and role-play method. The stages of the activity are carried out through several stages, namely the stages of planning, implementing, and evaluating. The results of the training have a significant impact on the level perception of knowledge of the trainees with an average of 70% understanding of the material presented.

Abstract

The power transfer system is an inseparable part of a vehicle unit, this component functions as a power source from the engine, increasing the moment generated by the engine according to the needs of the load and road conditions and reversing the rotation. Type As the age of the vehicle, the transmission it uses will be damaged or even fail to function, most automatic transmissions start having problems after the vehicle is used above 100,000 km or on vehicles that are not used in accordance with the provisions and do not carry out maintenance procedures properly, the automatic transmission is damaged. could come sooner. Based on the implementation of the Failures Mode Effects Analysis (FMEA) method which is used to evaluate components in a system by examining the potential failure model to determine the impact that will occur on the component or work system, it is found that the highest Risk Piority Number (RPN) is found in the Seal component. Piston Matic 450, Multiple Clutch/Clutch Pack 360, Selenoid Valve 324. Each potential failure model is classified based on the impact it can have on the success of the system or on user safety by dividing the categories using Logic Tree Analysis (LTA) with the results of most components automatic transmission is included in the type B failure (Outage Problem) where the component causes failure of all or part of the system. Based on the RPN value, the right maintenance is Predictive Maintenance.

Abstract

Mathematics is a lesson that is still a frightening specter for some students. There are several methods used to make mathematics fun to learn. One of them is to package material in mathematics to be more attractive and interesting, especially for children this can make them become interested in learning mathematics. The developed using research and development methods. This method begins by exploring the problem, collecting data needed, designing the product to be developed, validating the product design, testing the use of the system to be developed, revising the product, testing the product, revising the product and product design if there are errors or deficiencies and the last is mass production of product. This research aims to develop an interactive multimedia-based mathematics learning which can later be optimized to increase student interest in learning mathematics and be used to improve the quality of education.

Abstract

The use of information technology to improve people’s welfare has been implemented in various lines of life, including selling agricultural products through the marketplace to expand marketing and increase sales figures. Marketplace built based on the website using extreme programming (XP) method. The selection of extreme programming for marketplace development is tailored to all user needs and system requirements because website development is done in a relatively short time and many changes occur during website development. The stages of the extreme programming method are carried out in several iterations to get feedback from the end-users who are used in the website improvement process so that at the end of the iteration process the website developed is in accordance with the needs of the end-user. The output generated from this research is the farmer’s stall marketplace website that is used to market agricultural products from the Cilacap Holtikultura Farmers Association (PHC).

Abstract

Preeclampsia is a disease in pregnant women characterized by high blood pressure and positive urine protein. The disease has a high risk of maternal and fetal death, so there is a need for early detection of mothers at risk of preeclampsia. Early online detection of preeclampsia is the best solution during the Covid-19 pandemic by analyzing the influencing factors. The purpose of this study is to build an expert system for early detection of preeclampsia in pregnant women using the Certainty Factor method and the waterfall system development model in order to provide the possibility of pregnant women suffering from preeclampsia. Testing the accuracy of 30 medical record data for pregnant women resulted in a system accuracy level of 90%, while usability testing resulted in a user satisfaction level of 55 with the System Usability Testing (SUS) score criteria being "Poor", therefore improvements are needed on expert system in the future.

Abstract

Along with the development of smartphones, Augmented Reality technology has begun to be used as a medium of interaction, although it has not been properly implemented and applied as a supporting medium. The use of still image objects in textbooks can make students tend to be more passive and less interactive because media images are unable to provide a reciprocal response. In science subjects, there is solar system material regarding planet recognition. Props are needed as learning media because the object of observation from the planet is too large. Several props are used as imitations of the planets, such as the use of drawing paper, audio, and video. The purpose of this research is to make a breakthrough in the use of Augmented Reality technology to support media for understanding planet recognition material by creating digital teaching aids that can be installed on smartphone devices. The MDLC method is an alternative method for developing multimedia applications that are easy to understand. The results of the test show that the application can function as expected, where each planetary marker that has been made can be recognized properly according to the intended planetary object.
