Abstract

The critical objective of this present study is to conduct substantial evaluation of TOEFL as a language assessment tool. Using a qualitative method, the authors of the present study evaluated various specific issues based on a set of predetermined criteria such as practicality, test reliability, validity, authenticity, and washback impact. The analysis indicates that TEOFL ITP is both feasible and dependable. The TOEFL's dependability is based on these three components. However, unless the ITP test is altered from the previously used TOEFL, the TOEFL ITP is as reliable as the TOEFL PBT. In theory, its trustworthiness is uncertain, and more investigation is needed. It is debatable whether the TOEFL ITP test items can accurately represent this task when utilized for the placement test. TOEFL ITP is a reliable English test. Knowing the TOEFL significance encourages test takers to enhance their English skills as part of the exam. More students want to take lessons to enhance their grades.

Abstract

One of the benefits of artificial intelligence in the field of education is that it aids in writing. The aims of this research are to explore University students’ preferences in using AI for writing and investigate lecturers' perceptions regarding the use of artificial intelligence tools in EFL writing class. Qualitative research methods with case study design employed in this study. The data was collected by using questionnaires and interview. Ten EFL students and three lecturers from three different universities in Indonesia were involved as the respondents of this research. The findings revealed that there are nine types of AI ​​tools used by students in writing classes such as Quillbot, Grammerly, Chat GPT, Humata AI, Resume AI, Jenni AI, Perplexity, Deepl, and AI writing. Apart from that, the data also revealed the views of the lecturers on the use of AI. The data showed that AI writing tool have the influences on students' writing that the use of AI has received positive responses. Therefore, it can be inferred that Artificial Intelligence tools can be used in writing classes as long as it does not violate code in writing and not dependency.

Abstract

The Sumatran elephant (Elephas maximus sumatranus), classified as Critically Endangered, plays a vital role in maintaining tropical forest ecosystems. However, habitat degradation, fragmentation, and land conversion have escalated human and elephant conflicts in Sumatra. These conflicts cause severe economic losses, crop destruction, and over 200 elephant deaths between 2010 and 2023, mainly from poaching and retaliation. This review aims to examine mitigation strategies implemented in Bukit Barisan Selatan, Way Kambas, and Gunung Leuser National Parks, and to assess their effectiveness and sustainability. Using a literature review method, relevant scientific publications on elephant conflict mitigation were systematically analyzed. Findings indicate that combined structural and non-structural approaches such as sound deterrents, elephant trenches, tame elephant patrols, and community-based units (CRU and ERU) effectively reduce short-term conflicts. Long-term success, however, requires integrated, ecosystem-based strategies emphasizing habitat restoration, corridor connectivity, and adaptive land-use planning. This study highlights the need for humanistic and sustainable mitigation to foster coexistence between humans and Sumatran elephants.

Abstract

Capsicum chinense merupakan salah satu varietas cabai yang populer digunakan dalam masakan dan dikenal mengandung beragam senyawa bioaktif yang bermanfaat bagi kesehatan. Sebagian besar penelitian sebelumnya berfokus pada bagian buah, sementara tangkai yang berperan sebagai jalur transportasi nutrisi dan metabolit sekunder masih jarang dieksplorasi. Penelitian ini bertujuan untuk mengidentifikasi golongan metabolit sekunder yang terdapat dalam tangkai Capsicum chinense melalui skrining fitokimia. Sebanyak 50 gram serbuk tangkai cabai diekstraksi dengan metode maserasi menggunakan pelarut etanol 96% pada perbandingan 1:10 (b/v), kemudian filtrat diuapkan dengan rotary evaporator hingga diperoleh ekstrak kental. Ekstrak selanjutnya diuji secara kualitatif untuk mendeteksi keberadaan alkaloid, flavonoid, tanin, saponin, steroid, dan terpenoid. Hasil penelitian menunjukkan bahwa ekstrak tangkai Capsicum chinense memberikan reaksi positif pada uji Mayer dan Bouchardat, uji Salkowski, serta uji menggunakan akuades dan FeCl3, yang masing-masing mengindikasikan adanya senyawa alkaloid, terpenoid, saponin, dan tanin. Sebaliknya, uji flavonoid dan steroid tidak menunjukkan perubahan warna. Temuan ini menunjukkan bahwa tangkai Capsicum chinense berpotensi sebagai sumber senyawa bioaktif alami yang dapat dikembangkan lebih lanjut.
