Abstract

Abstract Heat is heat energy that can move from high temperature objects to low temperature objects. This research aims to analyze the effect of heat capacity in drying tobacco on the quality of the tobacco products obtained. In this research, the literature study research method was used. The results obtained are that the heat concept in the tobacco drying process is very influential, because the heat concept is the main key in removing water content from tobacco leaves. And there are several methods for drying tobacco that use the heat concept, namely the sun curing, flue curing and fire/smoke curing methods, but the methods that are often used by farmers in Indonesia for drying tobacco are the sun curing and fire/smoke curing methods. Factors that influence the efficiency and quality of tobacco products are land area, use of seeds, use of fertilizer, use of pesticides, use of labor, production and productivity of tobacco farming.AbstrakKalor merupakan energi panas yang dapat berpindah dari benda bersuhu tinggi ke benda  bersuhu rendah. Penelitian ini bertujuan untuk menganalisis pengaruh kapasitas kalor dalam pengeringan tembakau pada kualitas hasil tembakau yang didapatkan. Pada  penelitian  kali  ini  menggunakan  metode  penelitian  studi  literatur. Hasil yang didapatkan yaitu konsep kalor pada proses pengeringan tembakau sangat berpengaruh, karena konsep kalor merupakan kunci utama dalam menghilangkan kadar air dari daun tembakau. Serta terdapat beberapa metode pengeringan tembakau yang menggunakan konsep kalor yakni metode sun curing, flue curing, dan fire/smoke curing, akan tetapi metode yang sering digunakan oleh petani di Indonesia dalam pengeringan tembakau adalah metode sun curing dan fire/smoke curing. Faktor – faktor yang mempengaruhi efisiensi dan kualitas hasil tembakau yakni luas tanah, penggunaan bibit, penggunaan pupuk, penggunaan pestisida, penggunaan tenaga kerja, produksi dan produktivitas usaha tani tembakau. 
ANALISIS KORELASI KEMAMPUAN LITERASI SAINS DENGAN KEMAMPUAN MEMECAHKAN PERMASALAHAN KONSEP ENERGI TERBARUKAN PADA MAHASISWA PENDIDIKAN FISIKA Anggraeni, Sisilia Nur Hikmah; Sholehatennafiah, Vivi; Purwanti, Nurul Yunda Nanik; Pujiningtyas, Emma Berliana; Mahartika, Dina; Sudarti, Sudarti; Subiki, Subiki

Abstract

Literasi sains kemampuan menggunakan pengetahuan sains untuk mengidentifikasi pertanyaan, memperoleh pengetahuan baru, menjelaskan fenomena ilmiah dengan menyimpulkan berdasarkan bukti-bukti ilmiah. Penelitian ini bertujuan untuk mengetahui kemampuan literasi sains dan kemampuan memecahkan permasalahan sains mahasiswa Pendidikan fisika pada konsep energi terbarukan. Metode penelitian yang digunakan adalah metode analisis korelasi menggunakan kuisioner berupa google form yang disana nantinya akan mengetahui hubungan kedua variabel yang dibuktikan dengan aplikasi SPSS dan penelitian secara deskriptif. Hasil penelitian menunjukkan bahwa bahwa antara kemampuan literasi sains (X) terhadap kemampuan memecahkan masalah (Y) terdapat hubungan yang positif dengan tingkat korelasi sempurna. Hal tersebut tampak pada nilai koefisien korelasi Pearson di atas adalah 0,847 dimana nilai korelasinya bernilai positif sehingga hubungan antara Literasi Sains terhadap Kemampuan Memecahkan Masalah tentang Energi Terbarukan. Temuan hasil penelitian ini dapat digunakan untuk mengukur dan mengevaluasi sejauh mana literasi sains tentang energi terbarukan yang sudah diterapkan oleh mahasiswa pendidikan Fisika.

Abstract

Learning innovation is needed to make the learning process more attractive and improve student learning outcomes. Learning outcomes can be improved by making learning more interesting and developed according to student needs. Learning materials are packaged with different problem-solving methods that make learning more interesting to improve student learning outcomes. Based on existing findings, students' mathematical thinking skills are still relatively low. This study aims to measure the effectiveness of applying Cramer's rule to improve mathematical thinking skills and learning outcomes. This study uses a quantitative descriptive method which was carried out at Jember State High School and the Physics Education Study Program, Jember University in the odd semester of the 2024/2025 academic year. The results of data analysis from mathematical thinking skills affect the success of physics learning. The results of the homogeneity test and normality test that have been carried out show that the samples used are homogeneous and normal. The N-Gain value is obtained in the high category for improving mathematical thinking skills and learning outcomes. And the student response is very positive towards the use of Cramer's rule in solving the system of linear equations on the fixed pulley material. So it can be concluded that Cramer's rule in solving linear equation systems on pulley material remains effective in improving mathematical thinking skills and learning outcomes.
