Abstract

Feeding enriched with commercial probiotics is one solution to overcome the challenges in intensive catfish farming, especially related to the high cost of feed. Adding probiotics to feed can help reduce production costs while speeding up harvest time. Commercial probiotics containing bacteria such as *Lactobacillus*, *Acetobacter*, and *yeast* have been proven to be very effective in supporting catfish growth. Based on the advantages that have been revealed in various studies, the use of commercial probiotics is feasible to be applied and further developed in intensive catfish farming.

Abstract

Hybrid cantang grouper is the result of cross-breeding engineering between the Epinephelus lanceolatus and Epinephelus fuscoguttatus grouper species. This hybrid grouper was first developed by BPAP Situbondo under the auspices of the Ministry of Marine Affairs and Fisheries of the Republic of Indonesia. This article briefly explains the hybrid cantang grouper starting from morphology, habitat, reproductive cycle and cross-breeding methods.

Abstract

Productivity in aquaculture activities is often reduced due to disease outbreaks caused by various pathogens, including bacteria, viruses, and parasites. As an alternative to chemical treatments, a natural, plant-based approach—particularly through the utilization of flavonoid compounds derived from medicinal herbs—is being developed as a safer and more sustainable solution. This paper presents the author’s perspective, based on previous research, on the advantages of using plant-derived flavonoids for the treatment of cultured fish and discusses the potential negative impacts that may arise if such compounds are not integrated into aquaculture systems.

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

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

The tradition of "bedah ​​rumpon" is a fishing technique passed down through generations by the people of Ajibarang, Banyumas. This paper aims to examine this practice ethnographically and ecologically as part of local wisdom in managing inland water resources. This paper demonstrates that bedah rumpon functions not only as a fishing technique but also has strong social and cultural dimensions, including elements of mutual cooperation, seasonal rituals, and local water conservation. Although its effectiveness has declined due to declining fish populations due to environmental degradation, this practice is still maintained as part of local identity.

Abstract

Ikan coelacanth dikenal sebagai salah satu makhluk laut paling misterius di dunia karena selama puluhan juta tahun dianggap telah punah. Namun, penemuan ikan ini dalam keadaan hidup di perairan Indonesia mengejutkan dunia ilmu pengetahuan. Artikel esai ini membahas latar belakang penemuan coelacanth di Indonesia, mengenalkan ciri-ciri utamanya, serta menjelaskan mengapa temuan ini sangat penting bagi ilmu pengetahuan dan upaya pelestarian laut. Pembahasan menunjukkan bahwa coelacanth Indonesia merupakan spesies berbeda dari coelacanth Afrika dan hidup di laut dalam yang relatif masih alami. Penemuan ini membuktikan bahwa laut Indonesia menyimpan kekayaan hayati luar biasa sekaligus menuntut perhatian serius dalam perlindungan ekosistem laut dalam.

Abstract

The Pig-nosed turtle (Carettochelys insculpta) is a unique freshwater turtle species naturally distributed in southern Papua and Papua New Guinea. The presence of this species outside its natural habitat is a significant concern in conservation and invasive biology studies. This article aims to examine the presence of Carettochelys insculpta in the Jatiluhur Reservoir, Purwakarta, West Java, and the possible ecological impacts it may have on native species in the reservoir. Discovery data was obtained from an accidental catch by fishermen on December 14, 2025, using fishing nets in the Jatiluhur Reservoir. The research method used a desk study with data sources derived from scientific articles indexed by Google Scholar, online articles, and social media documentation on Facebook and TikTok related to the discovery of the species. Due to the lack of direct morphometric data, an estimation approach was carried out using Artificial Intelligence (AI) Gemini by analyzing the proportion of human hand size to the pig-nosed turtle's body in documentation photos. The analysis results showed that the individuals found had a Carapace Curve Length (CL) of approximately 45–55 cm, a Carapace Curve Width (CW) of approximately 35–45 cm, and a carapace diameter of approximately 40 cm, with an estimated total body length of 60–70 cm. These measurements indicate that the individuals were mature but had not yet reached the maximum size of the species. The presence of this species in the Jatiluhur Reservoir is suspected to be related to releases from the exotic or pet trade. The presence of C. insculpta has the potential to affect ecosystem balance through competition for space and food resources with local species, although further research is needed to determine the population status and its ecological impacts.

Abstract

Hatchery of tiger grouper (Epinephelus fuscogutattus) household scale is one of the contributors to the increase in national grouper seed production. with the hatchery of household-scale grouper, the demand for grouper seed can be fulfilled as well as improving the community's economy. This study aims to determine the hatchery of household-scale tiger grouper which includes the provision of feed, hatching eggs, water quality management, harvesting, Hatching Rate (HR) and Survival Rate (SR). Data collection methods by interview, observation and active participation. Observation results related to seeding began with the provision of natural food to harvest the seeds measuring 2.7-3 cm. Hatching Rate (HR) reaches 80% and Survival Rate (SR) reaches 20%. The seeds produced were 120,000 per cycle. Seed yields are 24,000 per cycle.
