Abstract

Abstrak Penelitian ini bertujuan untuk mengetahui kualitas briket dari campuran arang limbah bonggol jagung dan daun jati. Metode penelitian yang digunakan adalah metode eksperimen dengan membuat sebuah pproduk briket dan meganalisis kualitas produk briket yangdihasilkan dari nilai kadar air, kadar karbon, kadar volatile dan kalor. Variasi komposisi briketcampuran arang bonggol jagung dan daun jati 1:1, 2:1, 1:2 dengan persentase perekat tepung kanji5%, 10%, 15%. Hasilnya, Sampel yang memiliki kualitas bagus dari segi nilai kalor dan kadar abuadalah sampel C dengan kalor 7222,708 kal/g; kadar abu 3,13%, hanya saja kadar air 5,39% dankadar volatile 25,89%.

Abstract

Penelitian pendidikan fisika ini bertujuan untuk mengembangkan dan mengevaluasi instrumen soal berpikir kritis pada materi usaha dan energi. Metode penelitian yang digunakan merupakan penelitian pengembangan model ADDIE Desain penelitian ADDIE memiliki lima urutan prosedur penelitian, yaitu (a) analyze (menganalisis), (b) design (merencanakan), (c) develop (mengembangkan), (d) implement (mengimplementasikan), dan (e) evaluate (pengevaluasian). Hasil penelitian menunjukan bahwa soal yang memenuhi syarat sebagai instrumen yang valid dan reliabel adalah 10 soal dari total 20 soal. Instrumen soal yang baik diimplementasikan serta dievaluasi bahwa rata rata kemampuan berpikir kritis siswa berada pada kategori sedang. Hal ini menandakan bahwa rata rata siswa memiliki indikasi bahwa siswa memiliki pola berpikir kritis dengan kategori lambat dengan memanfaatkan pemikiran intuitif tanpa berpikir menggunakan konsep atau fakta (menganalisis permasalahan tidak sesuai argumentasi konsep, menuliskan jawaban tanpa melalui proses perhitungan).

Abstract

Research has been conducted which aims to increase understanding of the concept of material Electric Magnets through practicum methods using the Magnetic Electric Trainer which is created and developed using tools and materials in Merauke. Product development is done by making Magnetic Electric teaching aids for electromagnetic material, Induction GGL, Induction on straight wire and electric motors. Where props are made using tools and simple materials that are easily obtained, such as plywood, plastic pipes, cables and magnets. From the results of the application of the use of the Magnetic Electric teaching aids in SMP N 13 Merauke in class VIIID students, with the KKM value of 70 Natural Sciences lessons, the pretest results showed that no student passed the KKM. Then for the quiz score obtained by 5 students who passed the KKM and for the post-test scores obtained 18 students who passed the KKM with a total of grade VIII D students were 23 people consisting of 15 men and 8 women.
