Abstract

The problems faced by students are difficulties in understanding the questions and not having sufficient ability to work on new questions given by the teacher. The purpose of this study is to analyze the effect of the Problem Based Learning model assisted by the phET application on electricity learning materials. This type of research is quasi-experimental. The research population totaled 192 students. The total number of samples is 35 students. The method for obtaining data is the description test method. The instrument used is a description test. The data analysis technique is descriptive qualitative, quantitative and inferential statistical analysis. The results of the study are the results of the t-test which obtain t-count = 52.07 greater than t-table = 2.034, so that there is a significant difference in critical thinking ability between students who use the conventional model and students who are taught using the Problem-based Learning model assisted by the application of PhET material for class VI elementary school electricity. It was concluded that Problem-based Learning assisted by the PhET application could improve the critical thinking ability of fourth grade elementary school students in electricity material. The implication of this research is that Problem-based Learning can be used to improve critical thinking ability.

Abstract

Indonesia, which has significant human resources, needs better human resources. The efforts made by the government through the Independent Curriculum program, in fact, still need to be in line with expectations. Many students' potential has yet to be maximized, so innovation is needed to improve the quality of students through competitions and maximizing potential. This research aims to maximize students' potential and improve the quality of human resources in Indonesia. This type of research is qualitative, using quantitative research methods and t-test analysis. The research subjects were 60 students. The methods used to collect data are interviews, observations, and tests. The instrument used to collect data is test questions. Inference analysis was carried out using a Paired Sample T-Test. The Paired Sample T-Test results show a significant difference between the average achievement of students in the experimental group that uses the EXCELLA system and the control group that follows regular learning. The findings of this research have proven to have a positive impact on increasing student achievement and potential. This research implies that EXCELLA has excellent potential to become a practical learning innovation in improving the quality of Indonesian human resources. With continued support from the government and other stakeholders, EXCELLA can significantly create a superior and competitive future generation.

Abstract

Ayam pedaging mempunyai sifat genetik yang cepat dalam pertumbuhan, tetapi sangat rentan terhadap penyakit yang diakibatkan oleh mikroorganisme, hal ini menyebabkan para peternak ayam pedaging mengeluh akan kematian ayamnya secara tiba tiba. Para peternak ayam pedaging biasanya memeriksa kesehatan ayamnya dengan mengamati secara lansung, namun hal tersebut kurang efektif karena, jika hanya melihat dari segi tampilan fisiknya saja tidak menjamin kesehatan dari ayam itu sendiri. Tujuan penelitian ini adalah untuk menganalisis serta mengatasi permasalahan kesehatan ayam pedaging, dengan inovasi yang juga bertujuan untuk meningkatkan ketahanan pangan di Indonesia melalui peningkatan kualitas ayam pedaging. SASETAN merupakan sebuah inovasi dengan mengguakan metode penelitian kuantitatif serta melakukan percobaan kepada subjek ayam sebanyak 30 ekor ayam pedaging. Mekanisme kerja SASETAN meliputi input (sensor suhu, sensor detak jantung dan sensor suara), process (Arduino), dan output (LCD dan Buzzer) dengan data interval pembacaan Sensor Suhu 37-41; Sensor Detak Jantung 250-470; dan Sensor Suara adalah 18–23. Dan dari hasil percobaan yang telah kami lakukan, teknologi SASETAN dapat membantu para peternak ayam pedaging untuk mendeteksi kesehatan ayam sejak dini dan bisa mengurangi kerugian dari para peternak ayam pedaging. Berdasarkan analisis kelayakan teknis, teknologi SASETAN memiliki ketepatan dibandingkan sistem pengamatan secara langsung, serta memiliki kepraktisan dalam penggunaan. Implikasi hasil temuan ini adalah pengembangan teknologi SASETAN dapat memperbaiki efisiensi dan kesejahteraan hewan dalam industri peternakan ayam pedaging.
