Mengajar membaca di masa pandemi telah menjadi penhgalaman yang penting untuk situasi masa depan. Penelitian ini bertujuan untuk mengeksplorasi pengalaman guru bahasa Inggris pra-jabatan dalam mengajar pemahaman membaca di era pandemi COVID-19. Penelitian ini menggunakan penelitian kualitatif dan naratif inkuiri sebagai desain penelitian. Dua (2) guru bahasa Inggris pra-jabatan di sebuah universitas di Karawang, Jawa Barat, Indonesia berpartisipasi dalam penelitian ini. Teknik pengumpulan data dilakukan melalui wawancara semi-terstruktur. Peneliti menggunakan analisis tematik dalam menganalisis data. Temuan menunjukan bahwa guru pra-jabatan melakukan persiapan yang matang terhadap materi dan media sebelum mengajar, menggunakan pendekatan berbasis genre sebagai pendekatan yang disukai, dan memberikan evaluasi dan umpan balik setelah proses pengajaran. Ditemukan juga bahwa siswa mudah bosan, sulit memahami teks, dan keterbatasan waktu dalam belajar dan tidak efektif. Penelitian ini diharapkan dapat menjadi tolak ukur pengajaran pemahaman membaca selama masa pandemi. Peneliti - peniliti selanjutnya dapat mengeksplorasi lebih detail strategi – strategi yang digunakan dalam pembelajaran pemahaman membaca di masa pandemi.

Recount text is a staple material taught in the first year of Indonesian secondary schools yet research on this dominant ELT unit is limited despite the common observation of many students struggling to produce a well-written recount text. To address this research gap and problem, this study conducted a textual meaning analysis in the texts written by tenth-grade Vocational School. This study aimed to figure out the types of themes shown in 14 recount texts written by 14 students from two different vocational schools with other majors. The approach used the content analysis method and belonged to descriptive qualitative research. Content analysis is used as the technique to analyse the data considering Eggins’ 1994 Systemic Functional Linguistics (SFL) theory. The analysis revealed that most of the themes used are Unmarked Topical Themes. Every student has a different way of delivering messages in the Recount text that they made. Moreover, the researchers found Marked Topical Theme, Mood Adjunct Interpersonal Theme, Conjunction Textual Theme, Conjunctive Textual Theme, Continuative Textual Theme, and Multiple Theme. The result of the present study is hoped to provide insights, gained from observing patterns of Theme and Rheme relations, for secondary English teachers’ endeavours to help improve students’ cohesion.

Javanese eagle (Spizaetus bartelsi) is one type of bird of prey endemic to Java. The existence of birds of prey in an ecosystem is very important, because of its position as the top predators in the food chain or pyramid. The purpose of this study was to determine the characteristics and ecological nests, as well as the proliferation of Java Eagle Cikaniki especially in forest areas. Observation method used is cooperative mehod five observation points around forest areas Cikaniki. Through monthly observation, ranges Javanese eagle depicted on the map, and mapped point is the assumption of Javanese eagle nesting sites. Observations are also done through direct observation at the location around the nest. The results explain that Java Eagle identified seven individuals that belong to three families: Pengkeh family, relatives and family Andam I Andam II. During the observation, observed breeding success of one family, it is characterized by the presence of individual chicks that fly around the nest site. During the monitoring also the sound of Javanese eagle chicks in the vicinity of the nest. Cikaniki in forest areas, family observed using the Java Eagle Castanopsis argentea tree to lay a nest. The tree is a towering trees compared to other tree with a height of about 30 meters. Java Eagle nest situated at an altitude 16 meters above the ground on the second branch. Nest trees grow at an altitude of 1,100 meters above sea level and on a fairly steep slope topography, close to the creeks and within 500 meters of open wilayan limit.

Lithium recovery from brine is recently attracting significant attention due to increasing industrial demand for energy storage, such as batteries. The lithium recovery from lithium brine was investigated using hydrogen manganese oxide adsorbent. The hydrogen manganese oxide adsorbent HMn2O4 (HMO) is derived from the spinel lithium manganese oxide (LMO), which is synthesized from LiOH and MnO2 precursor through the reflux method. The synthesized adsorbent was characterized using Scanning Electron Microscopy to identify its physical characteristics and its surface morphology. The adsorption capacity toward lithium solution was performed through an ion exchange process, and the adsorption values were determined using Atomic Absorption Spectroscopy (AAS). The synthesized HMO has a high lithium adsorption capacity for lithium-ion, which is 23 mg/g, and 10 mg/g for desorption. The optimum uptake capacity of HMn2O4 is 44% of the initial values (52 ppm) after 120 minutes of contact time. The synthesized hydrogen manganese oxide adsorbent has a potential industrial lithium recovery for large-scale application.

This study aims to explore students' perceptions towards the use of animated movies in vocabulary lessons at SKB (Sanggar Kegiatan Belajar) Purwokerto. Using a descriptive qualitative approach, this research involved 20 seventh-grade students at SKB Purwokerto. Data were collected through a questionnaire consisting of 20 questions, as well as in-depth interviews with 7 students to enrich the findings. The results of the study showed that the majority of students had a positive perception of the use of animated movies in vocabulary lessons. They felt that animated movies made the learning process more engaging and helped them understand and remember new vocabulary more easily. Additionally, animated movies were also considered to increase students' motivation to learn. However, some students expressed negative perceptions, such as the use of animated movies taking up learning time and causing confusion due to the fast pace. Based on these findings, it is suggested that teachers consider using animated movies as an innovative and effective medium for vocabulary lessons, while still providing clear and structured guidance. This study contributes to the development of creative teaching strategies in English education at SKB Purwokerto.

Indonesia has a diverse range of freshwater fish species, making it possible for people to cultivate them. Goldfish are among the most economically valued freshwater fish species. Goldfish can be cultivated traditionally, as demonstrated by the indigenous people of Kasepuhan Citorek Lebak, Banten Province, who continue to practice traditional natural resource management. This project aimed to investigate goldfish farming utilizing an ethnozoological strategy to develop goldfish potential in the Kasepuhan Citorek and use it as the biology learning content. This study has been conducted in January 2024. Data were gathered through observation, in-depth interviews, and document analysis. Data analysis is carried out in a systematic manner using the triangulation technique. The results of the study found that the process of cultivating Sinyonya and Kumpai goldfish types in the Kasepuhan Citorek area still follows the customs for generations by utilizing the surroundings and can be used as the learning content in biology learning for grade ten senior high school in the basic competencies of biodiversity and ecosystem studies. Goldfish are kept in cages along the river. Kijing and rice field snails constitute 90% of their daily diet. The spawning process of one female with three or four male goldfish on the rice field can be harvested eight months later. Goldfish farming gives considerable economic benefits to the indigenous inhabitants of Kasepuhan Citorek.The uniqueness of goldfish cultivation in Kasepuhan Citorek, it can be concluded that this study can be recommended used as a biology learning content of ecosystem and biodiversity studies in senior high school level.
