Academic Letters is a new experiment in open access academic publishing. We aim to publish short-form articles such as brief reports, case studies, reports of new findings, socio-political critiques, credible scholarly opinions, and ideas omitted from previously published works. Articles published in Academic Letters are no longer than 600-1500 words, excluding references. Academic Letters is published periodically (6 issues per year: January, March, May, July, September, and November).

Abstract

This article discusses the rise of artificial intelligence (AI) based video production through the Google Veo 3 platform that highlights and criticizes police performance. The purpose of this article is to analyze how AI videos are used as a medium for social criticism, the narratives they construct, and the public's response to the content. The results of the study show that AI videos are used as an alternative space for expression in voicing disappointment with the performance of the police, especially in issues of abuse of authority and corruption. Although the videos are fictional and artistic in style, their visual and narrative power has a significant impact on public perception. This article concludes that generative AI such as Google Veo 3 opens up space for the democratization of criticism, but also raises ethical and regulatory challenges in the digital ecosystem so that there must be additional regulatory recommendations related to this.

Abstract

Stress menunjukkan ketidakseimbangan akibat respon awal terhadap stressor sehingga menghasilkan berbagai perubahan dalam fisiologis organisme. Respon stress memiliki pengaruh terhadap sistem kekebalan tubuh, hal ini mengacu pada durasi dan presistensi paparan stressor. Pada respon awal terhadap stress, pelepasan katekolamin dapat meningkatkan kinerja sel-sel sistem pertahanan tubuh. Sedangkan pelepasan kortisol terbukti memiliki efek penekanan terhadap kinerja sel-sel imun, hal ini menyebabkan peningkatan kerentanan ikan terhadap serangan patogen. Selain stress secara fisiologis, terdapat stress oksidatif yang diakibatkan ketidak seimbangan antara terbentuknya radikal bebas dengan kinerja antioksidan. ROS diproduksi oleh mitokondria, sel sel pertahanan tubuh dan lingkungan termasuk polutan. Pemaparan polutan dengan intensitas tinggi menunjukkan pengaruh peningkatan ekspresi sitokin pro inflamasi.

Abstract

Infeksi pathogen baik bakterian maupun virus merupakan tantang terbesar dalam industry Akuakultur di dunia. Untuk itu pemahaman akan mekanisme infeksi maupun resistensi terhadap pathogen perlu ditingkatkan agar dapat dijadikan dasar dalam menyelesaikan tantanngan tersebut. Transkriptomik merupakan metode yang dapat memuat semua gen yang terekpresi dalam regulasi tertentu, dalam analisa transkriptomik banyak digunakan rna-seq karena efektifitas dan akurasinya. Saat ini transkriptomik banyak digunakan untuk mempelajari mekanisme sistem pertahanan tubuh dalam merespos infeksi dan resistensi ikan terhadap pathogen tertentu. Informasi transkriptomik tersebut sangat berguna untuk pengembangan metode diagnostic, peningkatan Kesehatan dan sekelsi strain yang memiliki ketahanan terhadap pathogen tertentu.
Fenomena Maraknya Pengibaran Bendera One Piece Menjelang Hari Kemerdekaan Indonesia 17 Agustus 2025: Kajian Budaya Pop dan Nasionalisme Pratiwi Restu Murti; Muh. Sulaiman Dadiono

Abstract

Tulisan ini bertujuan untuk mengkaji fenomena sosial terkait maraknya pengibaran bendera bajak laut dari serial anime One Piece menjelang perayaan Hari Kemerdekaan Indonesia pada 17 Agustus 2025. Dari studi media sosial seperti Instagram, Youtube dan Tiktok menunjukkan bahwa pengibaran bendera Jolly Roger lebih mencerminkan ekspresi budaya pop, identitas komunitas, dan bentuk "nasionalisme alternatif" di kalangan generasi Z, dibandingkan dengan niatan untuk merusak simbol negara. Diskusi menyoroti pergeseran makna simbolik dan tantangan dalam membangun kesadaran kebangsaan di tengah globalisasi budaya. Oleh karena itu pentingnya pendekatan edukatif dan partisipatif dalam memahami ekspresi kebudayaan anak muda tanpa menekan kreativitas mereka.

Abstract

Bioremediation is an environmentally friendly approach to addressing pollution, particularly that caused by organic waste. Anaerobic bacteria play an important role in this process, especially in oxygen-depleted environments such as sediments and wastewater. This study aims to identify the role and mechanisms of anaerobic bacteria in the bioremediation process. The results of the study indicate that various types of bacteria, such as methanogens, sulfate reducers, hydrolytic bacteria, acidogenic bacteria, and acetogenic bacteria, are capable of breaking down complex organic compounds into simpler and safer compounds. Additionally, some species also play a role in addressing heavy metal contamination through biosorption and bioprecipitation processes. Metabolic processes such as fermentation, acetogenesis, and methanogenesis are key to the success of anaerobic bioremediation. This indicates that the utilization of anaerobic bacteria can serve as a sustainable, effective solution that aligns with the principles of a circular economy.
