Abstract

Reading is important and must be mastered by students, especially low class students such as class I and class II. By reading students can increase their knowledge and provide new insights to students. However, the facts on the ground still show a lack of reading ability in early grade students. In this way, flashcard media is used to change students' low reading abilities. This research aims to identify the relationship between the use of flashcard media and the reading ability of low grade students. The method used in this research is Systematic Literature Review (SLR). The articles studied in this research were 10 articles obtained from Google Scholar. Based on the literature review that has been carried out, it was found that the use of flashcard media has a good effect on the reading ability of low grade students, this is proven by an increase in student learning outcomes. ABSTRAKMembaca merupakan hal penting dan harus sudah dikuasai siswa, terlebih siswa kelas rendah seperti kelas I dan kelas II. Dengan membaca siswa dapat menambah pengetahuan serta memberi wawasan baru terhadap siswa. Namun, fakta dilapangan masih menunjukan kurangnya kemampuan membaca pada siswa kelas awal tadi. Dengan begitu digunakan media flashcard untuk merubah kemampuan membaca siswa yang masih rendah. Penelitian ini bertujuan untuk mengidentifikasi terkait penggunaan media flashcard terhadap kemampuan membaca siswa kelas rendah. Metode yang digunakan dalam penelitian ini yaitu Systematic Literature Review(SLR). Artikel yang dikaji dalam penelitian ini sebanyak 10 artikel yang didapatkan dari Google Schoolar. Berdasarkan kajian literatur yang telah dilakukan ditemukan bahwa penggunaan media flashcard berpengaruh baik terhadap kemampuan membaca siswa kelas rendah, hal ini dibuktikan dengan adanya peningkatan hasil belajar siswa.

Abstract

Ferronickel slag is a byproduct of nickel ore smelting. Several efforts have been made to find alternative applications for ferronickel slag, such as the production of construction materials, cement, or geopolymers. It is reported that 38% is used for road construction, 48% is used for industrial cement mixtures, and the rest is used for fertilizers, geopolymers, and hydraulic techniques. Ferronickel slag still contains some valuable minerals such as silica, magnesium, nickel, iron, and several REEs (rare earth elements). One of the REEs, namely lanthanum, has many applications, including Ni-MH (nickel-metal hydride) batteries, phosphors for lamps, fluid-cracking catalysts for oil refining, LaNi5 for hydrogen gas storage, metal alloys for cast iron, steel and magnesium alloys, additives for glassware (for cameras), and lanthanum hexaboride ceramic. In connection with the slag, which contains impurities in strong silica compounds, it is necessary to carry out an alkaline fusion treatment. Alkaline fusion was carried out by varying the time from 0.5 to 4 hours and the ratio of the mass of slag to NaOH: 1:0.6, 1:1, 1:1.23, 1:1.47, and 1:1.84. The biggest decrease in SiO2 was in the 3-hour alkaline fusion time, from 48.347% to 27.3%, and in the mass ratio at 1:1.47, from 48.347% to 21.413%. This research aims to provide added value for ferronickel slag by extracting lanthanum by acid leaching using H2SO4 reagent by varying the time (5, 10, 30, 60, and 120 minutes), temperature (30, 60, and 90 °C), and concentration (1, 2, and 3 M). The results showed that the best leaching point was at 5 minutes, 30 °C, and 1 M, yielding a lanthanum extraction percentage of 38.082%.
