App Development for Internship and Empowering Programs Using Cluster Detection Data Mining during PPKM (Restriction on Community Activities): A Case Study on Universitas Pendidikan Muhammadiyah Sorong of Indonesia

Internship and community service (KPM) were annual compulsory programs conducted by Universitas Pendidikan Muhammadiyah Sorong as the implementation of students’ tridharma, which were academic activity, research, and empowerment. These programs aimed at enabling students get experiences at schools, business field, and industrial field; implement knowledge, and could interact directly with community. The process of registration, allocating students and lecturers, submitting report and grading were still conducted manually. Thus, it resulted people crowd that resulted in a cluster for covid 19 spread. This research intended to develop an app for internship and empowerment programs where the decision making used cluster detection data mining. This app was expected to ease and fasten the registration process and break the crowd since it was accessed outside of campus area. Research method used was System Development Life Cycle) Model Prototyping. The app development consisted of: (1) need collection and analysis, (2) designing, (3) prototyping, (4) trial or evaluation test, and (5) implementation. Blackbox testing was the app trial test used to try the menus and procedures function to indicate that it have been up to the operational procedure standard. The black box test resulted that there was no functional error in the whole app for internship and empowerment programs.

Pelatihan Public Speaking Dengan Memanfaatkan Aplikasi Zoom Di Masa Pandemi Covid-19

One aspect that has changed due to the Covid-19 pandemic is the way humans communicate in public (public speaking). This impact was also felt by women who were members of the Fatayat NU (Nahdlatul Ulama) Ciledug organization. Fatayat NU is an Islamic women's organization which is one of the autonomous institutions within NU, which is religious, social and familial. The concept of Fatayat NU activities can be classified into three, namely in the field of regeneration and education, the field of da'wah or Islamic development, and the field of social society. The problems faced by Fatayat NU Ciledug, relating to public speaking are: (1) Lack of ability to appear and speak in public; and (2) Lack of public speaking skills, both face-to-face and online. The solutions offered to solve these problems are through community service activities, namely providing online training/workshops by utilizing the Zoom Meeting application to members of Fatayat NU Ciledug to provide tips and tricks regarding: (1) How to have the ability to appear and speak in public; and (2) Skills in public speaking both face-to-face and online. The implementation of this community service activity consists of 3 stages, namely; (1) The preparation stage, to identify problems, apply for permits to the Fatayat NU Ciledug management, and make preparations for the implementation of public speaking training; (2) the stage of implementing public speaking training; and (3) the evaluation stage, by providing evaluation test questions that must be done using Google Forms media, to find out how much the increase in knowledge, abilities, and skills of Fatayat NU Ciledug women regarding public speaking after participating in training activities.

Students’ understanding of the inverse square law in electrostatics

One problem of learning Electrostatics is that students often learn from their commonsense beliefs about electric force and electric field. This study investigated students’ conceptual understanding of finding electric force, electric field, and electric potential of point charge after learning an introductory physics course. We administered the Electrostatics Conceptual Evaluation Test to four lecture-based classes in high school. The first question was a comparison of the electric force from two-point charges at two different positions and the second question was a comparison of the electric field from a point charge at two different positions. The use of the inverse square law is required to find the electric force and the electric field at various positions. It was found that many students answered incorrectly. They described that the electric force and the electric field decrease whereas the distance increases by neglecting the inverse square law. This finding can be particularly used to suggest high school teachers to develop their effective strategy to support student learning.

Peningkatan Hasil Belajar Peserta Didik dengan Menggunakan Model Pembelajaran Discovery learning pada Kelas XI MA As’adiyah Putri Sengkang

This research is classroom action research. Teachers who are delivering learning materials do not use varied methods and always use the lecture method, so that most students do not understand and are not active in the learning process which results in unsatisfactory student learning outcomes. The purpose of this study was to determine the increase in student learning outcomes through the Discovery Learning cooperative learning model in biology class XI IPA MA As'adiyah Putri Sengkang. The subjects of this study were students of class XI MA As'adiyah Putri Sengkang, totaling 22 students. It was carried out in two cycles. Each cycle was carried out 3 meetings. At the end of cycles I and II, data was collected using a learning outcome evaluation test. The instruments used in this research are learning outcomes test questions and student activity observation sheets. The results showed that the application of the Discovery Learning learning model could improve student learning outcomes in biology class XI IPA 5 MA As'adiyah Putri Sengkang.

The subjects of this study were students of class 5A SD Negeri Bintoro 5 Demak, totaling 38 students. Data collection techniques using test and observation techniques. The instruments used in data collection were in the form of evaluation test questions at the end of the cycle and observation sheets. Data analysis used quantitative and qualitative descriptive.The results of the study showed that there was an increase in learning outcomes for human respiratory equipment through the application of the experimental method assisted by the puzzle picture media in 5A grade students of SD Negeri Bintoro 5 in the 2019/2020 school year. The increase in the average value of student learning outcomes from the pre-cycle of 58 to 69 in the first cycle and increased to 80 in the second cycle. The percentage of students' completeness also increased from 10 students (26%) in the pre-cycle to 22 students (66%) in the first cycle and 36 students (95%) in the second cycle.

Feasibility of Remote Performance Assessment Using the Free Research Executive Evaluation Test Battery in Adolescents

Lockdowns and other preventive measures taken to curb the spread of diseases such as COVID-19 have restricted the use of face-to-face cognitive assessment. Remote testing may be an alternative, but it should first be shown to be comparable to in-person assessment before being used more widely, during and after the pandemic. Our aim was to evaluate the suitability of online, examiner-mediated administration of an open-access battery of executive function tests (the Free Research Executive Evaluation battery, or FREE) that can be adapted considering various characteristics of diverse populations and therefore used worldwide. A total of 96 9–15-year olds (42 girls) were tested, half of whom online through video calls mediated by an examiner. Their performance was compared to that of the other 48 individuals tested face-to-face, who were matched against the online-tested participants for age, pubertal status, sex, and parental schooling. The battery consists of two tests of the following executive domains: Updating (2-Back and Number Memory tests), Inhibition (Stroop Victoria and Stroop Happy-Sad), and Switching (Color Shape and Category Switch). Answers were vocal and self-paced, and the examiner recorded accuracy and time taken to complete in-person and online tasks. Only free software is needed for the assessment. Executive measures obtained from the tasks did not differ statistically between online and in-person tested participants and effects sizes of group effects were small, thus showing that the FREE test battery holds promise for online cognitive assessment, pending confirmation in different samples and further validation studies.
