Abstract

Ikan selais (Ompok hypophthalmus) merupakan salah satu ikan endemik Riau. Ikan selais memiliki nilai ekonomis yang tinggi namun, kegiatan budidaya ikan selais cenderung terus menurun. Penelitian ini bertujuan untuk mengetahui pengaruh pengayaan kutu air menggunakan minyak jagung dengan dosis dan lama waktu pengayaan yang berbeda terhadap pertumbuhan dan kelulushidupan larva ikan selais. Penelitian ini dilaksanakan pada tanggal 1 Desember 2024 sampai 9 Januari 2025, yang bertempat di Laboratorium Pembenihan dan Pemuliaan Ikan Fakultas Perikanan dan Kelautan, Universitas Riau. Metode yang digunakan, Rancangan Acak Lengkap (RAL) dengan 2 faktor. Faktor pertama dosis dengan 4 taraf perlakuan yaitu 0,00 mL, 0,02 mL 0,04 mL, dan 0,06 mL sedangkan faktor kedua lama waktu pengayaan dengan 3 taraf perlakuan yaitu, 4 jam, 6 jam dan 8 jam setiap perlakuan dengan pengulangan 3 kali. Larva ikan diperoleh dari Balai Benih Ikan (BBI) Universitas Islam Riau. Parameter yang diukur adalah pengamatan usus kutu air, pertumbuhan panjang mutlak, pertumbuhan bobot mutlak, Laju pertumbuhan spesifik (LPS), kelulushidupan dan kualitas air. Hasil penelitian menunjukkan bahwa dosis dan waktu pengayaan yang berbeda memberikan pengaruh nyata (P<0,05) terhadap pertumbuhan dan kelulushidupan larva ikan selais. Perlakuan terbaik terdapat pada W4D4, dimana pertumbuhan panjang mutlak 5,63 cm, bobot mutlak 1,25 g, LPS 14,07% dan kelulushidupan larva ikan selais 96,66%. Parameter kualitas air tergolong optimal yaitu suhu 27 oC - 28,8 oC, pH 6,3 - 7, dan DO 6,3 - 7,1 mg/L.

Abstract

Ikan baung (Hemibagrus nemurus) merupakan salah satu ikan air tawar unggulan yang banyak digemari masyarakat karena rasanya yang gurih, kandungan protein tinggi, dan nilai ekonominya yang baik. Namun, dalam kegiatan pembenihan sering dijumpai kendala pada tahap larva, yaitu pertumbuhan yang lambat dan tingkat kelangsungan hidup yang rendah. Metode budidaya ikan baung untuk meningkatkan pertumbuhan dan survival larva dapat dilakukan melalui perendaman larva menggunakan probiotik. Probiotik dipilih karena mudah diaplikasikan, ramah lingkungan, dan mengandung mikroorganisme yang berfungsi memperbaiki sistem pencernaan serta meningkatkan daya tahan tubuh larva. Penerapan teknologi perendaman probiotik menghasilkan pertumbuhan larva yang lebih cepat, tingkat kelulushidupan lebih tinggi, serta benih yang lebih sehat dibandingkan dengan larva tanpa perlakuan.

Abstract

The rapid expansion of built-up land, measured as Impervious Surface Area (ISA), in Pekanbaru City has raised concerns about urban sustainability and regulatory compliance. This study develops a sustainable control model for built-up land growth integrating normative-legal and empirical-spatial perspectives. Using the Spatial Sustainability Assessment Model (SSAM) and GIS, 702,556 raster pixels of spatial data were analyzed, and systematic sampling generated 76 sample points for logistic regression analysis. Sixty-seven independent variables were examined, comprising biophysical (12), social (31), and economic (24) factors. Ensemble machine learning models, particularly CatBoost with GoldenFeatures, were applied to predict ISA growth and identify key drivers, including urban land values, population density, and the location of health and education facilities. Findings indicate that weak enforcement of relevant laws and regional regulations exacerbates unregulated land conversion. The study provides actionable insights for local governments, recommending stricter zoning enforcement, alignment with environmental laws, and targeted monitoring of high-risk areas to achieve sustainable urban growth. It recommends using the model for risk-based monitoring, enabling a shift from reactive penalties to proactive zoning enforcement to achieve sustainable urban growth.

Abstract

Mangrove forests in Riau Province play a vital role in carbon sequestration, coastal protection, and marine biodiversity conservation. This research examines the general condition of mangrove forests in Riau Province through literature review and content analysis of scientific articles published between 2017-2021. With a total area of 138,434 hectares distributed across seven regencies and cities, Riau's mangrove forests demonstrate significant carbon storage capacity, estimated at approximately 148 million tons of CO2 absorption. The research focuses on multiple observation points including Indragiri Hilir, Siak, Dumai, and Kepulauan Meranti to assess mangrove density, vegetation diversity, and ecological conditions. The findings reveal a concerning trend of declining mangrove coverage over the years, with vegetation area decreasing from 9,759 ha in 1997 to 7,875 ha in 2019 in Pulau Rangsang alone. Industrial activities, particularly oil industries operating in Riau Province, have been identified as significant factors affecting mangrove quality through heavy metal contamination (Pb), pH changes, and dissolved oxygen levels in coastal waters. Despite these challenges, mangrove forests in Riau continue to support diverse marine biota, with studies documenting 14 true mangrove species and 8 associated species in Sungai Pakning, and various zooplankton communities in Bandar Bakau. The research underscores the urgent need for comprehensive conservation policies and rehabilitation efforts to preserve Riau's mangrove ecosystems and their critical environmental functions.
