Abstract

Penelitian ini bertujuan untuk menganalisis peningkatan kemampuan berpikir geometri siswa KAM tinggi. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kuantitatif dengan metode kuasi eksperimen. Sample dalam penelitian ini adalah siswa kelas VII sebanyak 63 siswa di salah satu SMP di kota Bandung. Instrumen yang digunakan untuk mengumpulkan data adalah dengan tes. Sebelum dilakukan uji hhipotesis, data terlebih dahulu dianalisis dengan melakukan uji prasyarat yaitu, uji normalitas dan uji homogenitas. Setelah dilakukan uji prasyarat, selanjutny dilakukan uji hiipotesis dengan uji perbedaan. Hasil penelitian dan uji hipotesis menunjukan bahwa peningkatan kemampuan berpikir geometri siswa KAM tinggi yang memperoleh pembelajaran dengan model POGIL lebih tinggi secara signifikan daripada siswa yang memperoleh pembelajaran biasa. Hal ini terlihat dari jawaban-jawaban siswa dan peningkatan level berpikir siswa. Sebanyak 74% siswa dengan KAM tinggi meningkat level berpikirnya dari level 1 ke level 2 dan 25% siswa tetap berada pada level 1. Oleh karena itu model POGIL dapat digunakan dalam pembelajaran geometri, serta bagi peneliti yang akan melakukan penelitian sejenis sebaiknya juga menganalisis kemampuan berpikir geometri siswa dengan KAM sedang dan rendah

Abstract

The purpose of this study is to determine whether there are differences in the average learning outcomes of mathematics and which are higher average learning outcomes of mathematics between students who use the learning methods Problem Based Learning and Problem Solving. This type of research is experimental. Data analysis techniques using the ttes formula. The results showed that: (1) there were differences in the average learning outcomes of mathematics between students who used the Problem Based Learning and Problem Solving learning methods at SMPN 2 Metro, this was known based on the calculation of the hypothesis test obtained thit = 2,60 and tdaf = 2,00 so thit> tdaf. (2) the average student learning outcomes using the Problem Based Learning method are higher than the Problem Solving learning method in mathematics learning for VIII grade students of SMP Negeri 2 Metro 2016/2017 Academic Year, this is known based on the two average test difference, obtained thit = 2,53 and tdaf. = 1,67 so thit > tda

Abstract

Penelitian ini bertujuan untuk mengetahui deskripsi kemampuan pemecahan masalah siswa dalam menyelesaikan permasalahan yang berkaitan dengan materi Sistem Persamaan Linier Dua Variabel (SPLDV). Subjek penelitian adalah siswa kelas VIII Absyah MTs Babul Hikmah Kalianda yang berjumlah 30 siswa. Jenis penelitian yang digunakan adalah penelitian kualitatif. Pengumpulan data dengan menggunakan observasi, wawancara, tes dan dokumentasi, dimana instrumen tersebut telah diverifikasi oleh validator ahli. Analisis data yang dilakukukan dengan empat tahap yaitu reduksi data, pemaparan data, analisis tujuan penelitian dan menarik kesimpulan. Hasil penelitian menunjukkan masih banyak langkah penyelesaian matematis yang tidak dilakukan oleh siswa sehingga memperoleh hasil yang kurang tepat. Masih ditemukan kekeliruan dalam pengoperasian pada tahap pelaksanaan rencana. Serta kemampuan pemecahan masalah matematis siswa pada materi SPLDV perlu ditingkatkan karena masih banyak siswa yang belum melaksanakan tahapan pemecahan masalah matematis dengan tepat.

Abstract

 The COVID-19 pandemic has impacted various aspects of people's lives, including the economic sector that occurred in Tanjung Waras Hamlet, Merak Batin Village, RT 15, South Lampung. The observations show the residents' lack of knowledge and creativity in managing the harvest of chicken livestock to improve the creative economy of the residents. Therefore, to maximize this potential, our community service team from the University of Muhammadiyah Lampung assists the community by utilizing chicken harvest to improve the economy. The research method used is qualitative, with activities consisting of preparation, assistance, implementation, evaluation, and monitoring. Data is collected using observation techniques, questionnaires, interviews, and group discussion forums (FGD). This activity was carried out on 6-12 July 2021 in Tanjung Waras Hamlet, Merak Batin Village, RT 15 participants with 20 participants. The results of this activity show that: 1) 90% of respondents succeeded in making frozen food products made from chicken. 2) sales results after being processed into frozen food products provide profits of up to more than 75%. This also makes residents more creative in processing raw chicken pieces into processed products that can provide income and help residents overcome economic problems during the COVID-19 pandemic. Marketing of processed products is carried out by residents from home and also through social media.

Abstract

Advances in science and technology have brought enormous changes to the advancement of education, especially for teachers to improve pedagogical competence. Therefore, teachers must be able to design learning that can transfer knowledge and information well to students. This service program was carried out at SMP N 7 Pesawaran with the aim of providing assistance to teachers in the interactive learning of Auto Play Media Studio 8 (AMS) based on blended learning. The methods used in this training include training on AMS 8 applications that produce products made by participants using the ADDIE development. The results of this service (1) increase teacher knowledge and skills by 92,9% of the 44 participants, 85,3% of teachers on average are able to implement blended learning-based Auto Play Media Studio 8 (AMS) learning media (2) help answer learning at this time, especially in the Covid-19 pandemic conditions which causes students to not be able to learn directly by coming to school so that teachers can apply innovative learning to increase student motivation in learning.
