Abstract

Sungai Karangsong merupakan salah satu sungai terbesar di Kabupaten Indramayu yang banyak dimanfaatkan masyarakat sekitar. Permasalahan yang terjadi di Sungai Karangsong adalah masyarakat kesulitan memanfaatkan air sungai karena airnya payau. Bertambahnya aktifitas di aliran Sungai Karangsong serta pengaruh pasang surut dapat menyebabkan terjadinya intrusi air permukaan. Penelitian ini dilakukan dengan tujuan untuk mengetahui distribusi salinitas di aliran estuari Sungai Karangsong dan mengetahui hubungan antara elevasi pasang surut, arus pasut dan jarak jangkauan terhadap sebaran salinitas di kedalaman berbeda di Sungai Karangsong. Penelitian ini dilakukan pada tanggal 15 Mei sampai dengan 19 Mei 2015. Metode analisis menggunakan metode regresi berganda dan pendekatan nilai daya hantar listrik. Nilai daya hantar listrik di sepanjang estuari Sungai Karangsong berkisar 2760 Mikrosiemens sampai dengan 35400 Mikrosiemens pada jarak jangkauan hingga 4050 meter dari muara sungai. Berdasarkan hasil analisis regresi linier berganda terhadap semua variabel didapatkan nilai koefisien determinasi (R2 atau R square) sebesar 99 %. Angka tersebut mempunyai arti bahwa semua variabel bebas berupa elevasi pasang surut, arus pasut dan jarak jangkauan memiliki hubungan dan pengaruh nyata terhadap sebaran salinitas.

Abstract

English as a Foreign Language (EFL) evolves to include reading, writing, listening, and speaking. Writing is crucial in higher education for academic report preparation and final project requirements by developing a proper summary. However, there is a lack of research on enhancing summary writing skill in EFL contexts. The Bloom taxonomy model can help to develop students' cognitive analysis. Therefore, this study aims to examine the difference in summary writing skills among EFL students taught using Bloom taxonomy questions. To achieve this aim, a quasi-experimental method was employed by two groups: an experiment group and a control group. The experimental group was taught summary writing strategies using Bloom taxonomy questions, while the control group received a control group. Both groups were given a pre-test and a post-test before and after the treatment. The results showed that the pre-test scores and post-test scores were similar between the experimental and control groups. However, the paired sample t-test showed a significant difference between pre-test and post-test scores in the experimental group, indicating a significant increase in results. The study provided valuable insights into the effectiveness of different treatment methods in improving students' summary writing skills. In conclusion, the study shows that Bloom taxonomy questions can significantly enhance students' summary writing skills, as they are more attractive, hierarchical, and cognitively domain-specific than conventional teaching methods. The experimental group achieved higher mean scores. The results suggest that EFL teachers should select appropriate source texts and future research should consider locations and subjects.

Abstract

English as a Foreign Language (EFL) learners around the world have access to various tools for their writing skill enhancement. Those tools are commonly accessed with automated written corrective feedback to help them minimize the errors in writing due to its time efficiency. Additionally, the examples of the written corrective feedback used by EFL learners are commonly Grammarly, Hemingway app, and AI grammar checker. However, they fail to address the pointed needs of EFL learners in writing skill enhancement where English is not the native language, such as the practices in non-native developing countries. Due to writing skill enhancement as the aim of this study, the EFL learners' participation is crucial to its efficacy by conventional model, instead of the automated one. To answer this issue, this study presents a Systematic Literature Review (SLR) analysis of conventional written corrective feedback as learning as the appropriate model for EFL learners' writing skill enhancement as the reflective practices in light of the shortcomings for EFL learners' writing skill enhancement in Indonesia. This SLR study demonstrates that the conventional written corrective feedback has the potential to support the Indonesian EFL learners' writing skill enhancement by comparing current practices of the corrective feedback as learning for EFL learners in Indonesia with national practices and international ones dealing with non-native developing countries reported in the literature. The conventional written corrective feedback is expected to be an efficient sustainable model to enhance the EFL learners' writing skill because of its empowering organic form.

Abstract

Most people learn English. Science, culture, and international relations necessitate it. Many students join an English course to study with friends outside of school since the course is offline sessions or busy schedules. Therefore, this study investigated using Zoom meetings to teach speaking in several English-learning programs at a prominent English-study institution. Qualitative research was used to gather expert information from entrepreneurs and teachers. This research examines online speaking teaching tactics using observation sheets and Zoom Cloud Meeting interview recordings. The findings showed that teachers' online speaking education methodologies meet students' requirements. They motivate students, utilize real language in relevant circumstances, and engage them. Teacher corrections and comments. Using the natural interaction between speaking and listening may also improve the lesson. Offering students options creates a lively classroom. Each session ends with professors encouraging students to use instructional speaking. This project intends to enhance future English class Internet research.

Abstract

Coastal areas have high ecosystem productivity and are characterized by abundant fish species and coral reefs. However, these ecosystems are vulnerable to environmental pressures caused by human activities and natural dynamics. Coral reefs, consisting of organisms from the class Anthozoa within the order Scleractinia, which produce calcium carbonate structures, are key indicators of coastal ecosystem health. Coral reefs share biological characteristics with soft corals, hydras, and sea anemones as part of the phylum Cnidaria. Their existence is highly sensitive to environmental changes, whether natural or anthropogenic. In Indonesia, coral reef conditions have experienced significant degradation, with 36.18% in the damaged condition, only 6.56% categorized as very good, and 22.96% as good. The remaining 34.3% fall under the poor category, particularly around Karimunjawa and Kemujan Islands. Accurate data-based monitoring and management are essential for conserving these ecosystems. One method used to map and analyze coral reef distribution is the Lyzenga algorithm, which can distinguish shallow-water characteristics from coral reef habitats using satellite imagery. In this study, the Lyzenga algorithm was applied to SPOT 6 imagery for the Karimunjawa and Kemujan regions, covering an area of 8.46 km². The results showed that live coral reefs cover approximately 46% of the area, while dead coral reefs account for 56%, indicating a level of degradation that requires further attention in conservation and ecosystem recovery strategies. This study highlights the critical state of coral reefs in Indonesia, particularly in the Karimunjawa and Kemujan regions, emphasizing the necessity for conservation efforts driven by precise monitoring techniques such as the Lyzenga algorithm.
