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%.

Abstract

Until now, more than 95% of the material needs for medical devices are still imported, independent mastery of technology can at least reduce dependence on imported implant materials. On the one hand, the increase in the welfare of the population in Indonesia today is directly proportional to the increase in life expectancy of the population. The above conditions will have an impact on the increase in the number of elderly people. The increase in the elderly population will potentially increase the occurrence of degenerative bone diseases suffered by the elderly. This study aims to analyze the effect of the thermomechanical process through hot rolling. The added Mo and Nb elements function as beta phase stabilizers which will certainly affect the microstructure and mechanical properties of titanium alloys. The thermomechanical heat treatment process is an advanced process where the homogenized ingot is then hot rolled at a temperature of 1100 °C in 3 rolling stages until it reaches a 50% reduction. Then characterized by observing the microstructure and mechanical properties. The thermomechanical process involves plastic deformation at high temperatures that affect changes in microstructure and mechanical properties. Plastic deformation combined with recrystallization results in smaller grain sizes, which improves mechanical properties with a relatively uniform increase of 429–450 VHN. Therefore, this thermomechanical processed Ti-5Mo-9Nb-based alloy has the potential for improved medical implant material applications. Abstrak: Sampai saat ini kebutuhan material untuk alat kesehatan lebih dari 95% masih impor, penguasaan teknologi secara mandiri setidaknya dapat mengurangi ketergantungan impor material implan. Di satu sisi, peningkatan kesejahteraan penduduk di Indonesia dewasa ini berbanding lurus dengan meningkatnya usia harapan hidup penduduk. Kondisi tersebut di atas akan berdampak terhadap peningkatan jumlah penduduk usia lanjut. Meningkatnya penduduk usia lanjut akan berpotensi pada terjadinya penyakit tulang degeneratif yang diderita oleh para lanjut usia akan semakin meningkat. Penelitian ini bertujuan untuk menganalisis pengaruh proses termomekanik melalui pengerolan panas. Unsur Mo dan Nb yang ditambahkan berfungsi sebagai penstabil fasa beta yang tentunya akan memengaruhi struktur mikro dan sifat mekanis paduan titanium. Proses perlakuan panas termomekanik merupakan proses lanjutan di mana ingot yang telah dihomogenisasi kemudian dilakukan pengerolan panas pada temperatur 1100 °C sebanyak 3 tahapan pengerolan sampai mencapai reduksi 50%. Kemudian dikarakterisasi melalui pengamatan struktur mikro dan sifat mekanik. Proses termomekanik melibatkan deformasi plastis pada suhu tinggi yang memengaruhi perubahan mikrostruktur dan sifat mekanis. Deformasi plastis yang dikombinasikan dengan rekristalisasi menyebabkan ukuran butir menjadi lebih kecil, yang meningkatkan sifat mekanis dengan peningkatan yang relatif seragam 429–450 VHN. Sehingga paduan berbasis Ti-5Mo-9Nb melalui proses termomekanik ini berpotensi untuk aplikasi material implan medis yang lebih baik.

Abstract

The performance of irrigation networks serves as an indicator of management that encourages the optimization of water use in an effective and efficient manner to meet increasing demands. However, in practice, several problems are still encountered, such as uneven water distribution, suboptimal infrastructure conditions, and institutional management that has not functioned optimally. Therefore, assessing the Irrigation System Performance Index (IKSI) is important, one of which is through collecting IKSI form data for each irrigation area in the Special Region of Yogyakarta (DIY) to obtain a quantitative value of irrigation system performance. This study aims to assess the IKSI in one of the irrigation areas in the Special Region of Yogyakarta, namely the Gamping Irrigation Area. The method used in this study includes data collection through field observations, interviews with related stakeholders, and data processing based on IKSI parameters, which consist of physical infrastructure, crop productivity, supporting facilities, personnel organization, documentation, and the institutional condition of Water User Associations (P3A). The results indicate that the performance of the irrigation system in the Gamping Irrigation Area falls into the good category, with several parameters such as physical infrastructure and crop productivity in optimal condition. However, some parameters show relatively low values, such as documentation and institutional aspects, which require improvement. Therefore, improvement efforts can be carried out through enhancing documentation, strengthening P3A institutions, as well as maintaining and rehabilitating irrigation networks to improve overall system performance.
