Kemampuan literasi sains siswa akan menjamin ilmu pengetahuan yang diperoleh akan bertahan lebih lama sehingga akan berdampak pada minat belajar siswa yang semakin meningkat. Metode penelitian ini adalah penelitian kuantitatif deskriptif, dimana penelitian ini bertujuan untuk mengetahui pengaruh variabel kemampuan literasi sains terhadap minat belajar siswa mata pelajaran pewarisan sifat kelas IX di SMP Darul Hikmah. Teknik pengumpulan data yang dikumpulkan menggunakan teknik tes menggunakan LKPD dan kuesioner. Teknik analisis data pada penelitian menggunakan uji normalitas dengan rumus Kolmogorov-Smirnov dan analisis regresi linier berganda. Hasil rata-rata persentase skor indikator paling tinggi terdapat pada aspek kompetensi sains indikator menjelaskan fenomena sains sebesar 96% dengan kategori sangat “tinggi”. Hasil rata-rata persentase skor indikator tertinggi terdapat pada indikator perasaan senang sebesar 80% dengan kategori “sangat tinggi”. Dari hasil penelitian yang telah dilakukan didapat bahwa kemampuan literasi sains memiliki pengaruh yang signifikan terhadap minat belajar siswa mata pelajaran pewarisan sifat kelas IX di SMP Darul Hikmah.
The purpose of this research is to find out how to determine the Qibla direction of aplace using the position of the planet Venus and how to prove the calculation of the position ofVenus in the sky. This research is motivated by the question of how to determine the Qibladirection at night if the conditions do not have sophisticated technological equipment. Thisresearch is a descriptive analysis research where all the data is collected through observationtechniques. The research results show that the position of the planet Venus can be used as analternative reference to determine the Qibla direction. Based on observations using astronomicalcalculations, it is known that Venus looks very luminous on the western horizon when the sky isclear and the sun has set perfectly. We can also see one of the planets Venus at dawn on theeastern horizon, so Venus is also often referred to as the morning star. Data on the position of theplanet Venus such as the altitude and azimuth of the planet Venus somewhere are then calculatedusing the horizon coordinate system. The data is used as a theodolite reference. Furthermore, toobtain the actual Qibla direction, the theodolite lens is directed to the position of the planet Venusand rotated clockwise (same as the difference in the azimuth angle with the Qibla azimuth ofVenus). Thus, the position of the planet Venus can be used as an alternative to determine the Qibladirection.
Electronic student worksheets or E-LKPD are teaching materials designed digitally to support the learning process based on science, technology, engineering mathematics or STEM to increase student creativity through project design, planning activity schedules or work plans. This study aims to develop a valid, practical, and effective STEM-based E-LKPD in increasing the creativity of junior high school students. The methodology used in this research is research and development (RD) with the ADDIE model, namely analysis, design, development, implementation, and evaluation. The analysis stage is to determine and define student needs through interviews with teachers and students. The design stage is done by designing a STEM-based E-LKPD that suits the needs in terms of design, language, and materials. The development stage is carried out by developing products that are validated by validators, namely material experts, media experts, and science subject teachers to determine the feasibility of the product. The implementation phase is a trial using STEM-based E-LKPD on student creativity. The evaluation stage is carried out with the final revision of the product developed in accordance with the input suggestions at the implementation stage. The results of the study can be concluded that the STEM-based E-LKPD on temperature and heat materials to increase the creativity of junior high school students shows results with valid, practical, and effective categories
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
