Zooxanthellae are symbiotic microalgae that live within coral tissue, playing a vital role in photosynthesis and providing energy to the coral through their metabolic products. The abundance of Zooxanthellae in coral can be influenced by various environmental factors, one of which is light intensity. The aim of this study was to determine the abundance of Zooxanthellae in branching corals (Acro…
Asian redtail catfish (Hemibagrus nemurus) is widely found in Riau waters and has high aquaculture potential. Larvae are usually fed tubifex worms, but their limited availability requires alternatives. Commercial feed PF-0 can be used in paste form, though it is less digestible for larvae. Fermentation and ginger powder supplementation may improve feed utilization. This study aimed to determine…
Pasta feed is one of the alternative replacement feed naturally occurring in the cultivation of Asian redtail catfish (H. nemurus) larvae. However, pasta feed is not yet able to completely replace the silk worm, and enrichment feed pasta with oils from mesenteric waste catfish, expected to improve the performance of pasta feed. The aim of this research was to determine the effect of enriching f…
Catfish is one type of freshwater fish that is cultivated and is a food ingredient for Indonesian people, therefore it is necessary to carry out cultivation engineering that can increase fish growth to meet the needs of the community. This study aims to determine the effect of thyroxine hormone immersion on the growth and survival of local catfish larvae and to determine the optimal dose of thy…
The philippine catfish (Clarias batrachus) is a freshwater species of high economic value, however, its cultivation faces constraints due to adhesive eggs that clump together and hinder hatching. This study aimed to determine the effect of immersing philippine catfish eggs in black tea (Camellia sinensis) solution with different doses and immersion times on egg adhesiveness, fertilization rate,…

This study was conducted for 50 days from March to April 2025 which took place at the Hatchery, Faculty of Fisheries and Marine Sciences, University of Riau. The method used in this study was …
ABSTRACK Inclusive education, particularly in the learning of Hijaiyah letters (Arabic alphabet), remains a significant challenge for deaf students. Conventional media often fails to bridge this communication barrier, a problem exacerbated by the difficulty of distinguishing between several very similar hand gestures, a real issue observed at SLB Panam Mulia Pekanbaru. To address this gap …
ABSTRACT The gaming industry has grown rapidly, and one of the key elements in a game is the non-playable character (NPC). Easily predictable NPC behavior often reduces player engagement and satisfaction. Static or unresponsive NPCs tend to create monotonous and less challenging gameplay experiences, ultimately lowering game quality and player interest. This study applies Deep Reinforcement Le…
ABSTRACT This study aims to design and develop a store security system based on the Internet of Things (IoT) to enhance monitoring effectiveness and real-time store security. The system utilizes an ESP32-CAM as the main controller, integrated with a PIR sensor, two servo motors, and a Telegram Bot as a notification medium. It is designed to detect motion, capture images, and display livest…
ABSTRACT The increase in population and industrial activity in the Payung Sekaki District of Pekanbaru City has had an impact on the increase in waste entering the Muara Fajar landfill. According to Presidential Regulation No. 97 of 2017, 30% of waste must be managed at the source, and the limited capacity of each subdistrict to reduce waste is one of the main problems that is predicted to con…
ABSTRACT The high accumulation of soybean seed coat and tofu dregs waste contributes to environmental problems, therefore, an effective and eco-friendly waste management alternative is needed. One potential solution is the utilization of Black Soldier Fly (BSF) larvae. This study aimed to evaluate the effect of fermented feed variations of soybean seed coat and tofu dregs on the performanc…
Hemibagrus nemurus is a high-value freshwater aquaculture species, yet its growth is relatively slow due to inefficient feeding management. Maggot meal (Hermetia illucens) has great potential as an alternative feed ingredient because of its high protein content and easy availability.
