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.

Abstract

The Betok fish (Anabas testudineus) is one of the freshwater fish species with potential for aquaculture. Larvae rearing faces challenges, namely low survival rates due to low nutrient content in the feed. Therefore, it is necessary to supplement Moina sp. with viterna. This study aims to determine the optimal dose of viterna in Moina sp. supplementation to improve the survival rate and growth of Betok fish larvae. The method used is an experiment. The experimental design employed is a Complete Randomised Design (CRD) with one factor and three treatments, each repeated three times. The treatments involved enriching Moina sp. with viterna at different doses: D0 = 0 ml/L (control), D20 = 20 ml/L, D40 = 40 ml/L, and D60 = 60 ml/L. The results of the study showed that the enrichment of Moina sp. with different viterna doses affected the survival rate and growth of betok fish larvae. The best treatment was D60, with absolute weight growth of 0.47 g, specific growth rate of 8.01%/day, absolute length growth of 2.64 cm, and survival rate of 93.33%. The water quality parameters obtained included temperature 26–29.1°C, pH 6.3–7.1, and dissolved oxygen (DO) 5.3–6.2 ppm.

Abstract

Riset ini dilakukan untuk mengkaji dampak perendaman telur ikan lele lokal (Clarias batrachus) dalam larutan teh hitam (Camellia sinensis) dengan takaran serta durasi yang bervariasi terhadap proporsi telur melekat, proporsi fertilisasi, proporsi penetasan, dan kelangsungan hidup larva. Pelaksanaan riset berlangsung pada 5–10 Mei 2025 di Laboratorium Pembenihan dan Pemuliaan Ikan, Fakultas Perikanan dan Kelautan, Universitas Riau, Indonesia. Pendekatan yang diterapkan dengan rancangan acak lengkap faktorial dengan dua faktor, meliputi takaran larutan teh hitam (0, 6, 8, dan 10 g L-1) serta durasi perendaman (2, 4, dan 6 menit), masing-masing dengan tiga ulangan sehingga menghasilkan 36 unit percobaan. Parameter yang dicermati mencakup proporsi telur melekat, telur tidak melekat, proporsi fertilisasi, proporsi penetasan, kelangsungan hidup, serta mutu air. Temuan riset memperlihatkan bahwa variasi takaran dan durasi perendaman berdampak nyata terhadap keseluruhan parameter yang dicermati (p < 0,05). Kombinasi optimal untuk proporsi telur melekat dijumpai pada takaran 10 g L-1 selama 6 menit (W6D3), sementara untuk derajat fertilisasi, proporsi penetasan, dan kelangsungan hidup, capaian terbaik diraih pada takaran 10 g L-1 selama 4 menit (W4D3). Dosis 10 g L-1 merupakan konsentrasi paling efektif untuk seluruh parameter, dengan waktu perendaman 4 menit lebih optimal bagi keberhasilan pembuahan, penetasan, dan sintasan larva, sedangkan 6 menit lebih sesuai untuk menurunkan persentase telur merekat. Perbedaan ini menunjukkan bahwa perendaman terlalu lama dapat menurunkan kualitas fisiologis telur meskipun efektif menurunkan persentase telur merekat ikan lele lokal.This study aimed to determine the effect of immersing local catfish (Clarias batrachus) eggs in black tea (Camellia sinensis) solution at different dosages and immersion durations on the percentage of adhesive eggs, fertilization percentage, hatching percentage, and larval survival rate. The study was conducted from 5 to 10 May 2025 at the Hatchery and Fish Breeding Laboratory, Faculty of Fisheries and Marine Sciences, Riau University, Indonesia. A factorial completely randomized design was applied with two factors: black tea solution doses (0, 6, 8, 10 g L-1) and immersion times (2, 4, and 6 minutes), each with three replicates, resulting in 36 experimental units. The observed parameters included the percentages of adhesive and non-adhesive eggs, fertilization and hatching percentages, survival rate, and water quality. The results showed that different dosages and immersion durations had a significant effect on all observed parameters (p < 0.05). The best treatment for the percentage of adhesive eggs was obtained at a concentration of 10 g L-1 with an immersion time of 6 minutes (W6D3). Meanwhile, the highest fertilization rate, hatching rate, and larval survival rate were achieved at a concentration of 10 g L-1 with an immersion time of 4 minutes (W4D3). The 10 gL-1 concentration was the most effective for all parameters. An immersion time of 4 minutes was more optimal for fertilization success, hatching, and larval survival, whereas a 6-minute immersion was more effective in reducing egg adhesiveness. These differences indicate that excessively long immersion durations may reduce the physiological quality of eggs, although they are effective at reducing egg adhesiveness in local catfish.

Abstract

Glofish Tetra (Gymnocorymbus ternetzi) is a transgenic product of tetra fish in which a fluorescent gene from jellyfish is inserted into the fish egg genome, resulting in heritable expression of fluorescent protein. Currently, glofish is one of the most sought-after ornamental fish commodities, so it has high economic potential in the cultivation sector. The success of ornamental fish cultivation is influenced by the quality and type of feed given from the larval to broodstock phase. This study aims to determine the effect of providing different types and combinations of natural feed on the growth and survival of glofish tetra larvae. This research was conducted for 40 days in May - July 2025, located at the Fish Breeding and Cultivation Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau, Pekanbaru. The method used in this study was an experimental method using a one-factor Completely Randomized Design (CRD) with 4 treatment levels and 3 repetitions. The larvae used in the study were 7 days old and underwent feed adaptation for 2 days from the results of natural spawning carried out at the Fish Spawning and Breeding Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. Feeding is done with a frequency of three times a day, namely at 08.00, 12.00, and 17.00 WIB, and is given to the larvae using the ad-satiation method. The parameters measured in this study were absolute length and absolute weight growth, larval growth rate, larval survival, larval response to feed and water quality. The results of the analysis of variance (ANOVA) test showed that providing different types and combinations of natural feed had a significant effect (P<0.05) on absolute length growth, absolute weight growth, specific growth rate and survival of glofish tetra larvae. The best treatment was P2 (AR2T4) with an absolute length of 2.34±0,01cd cm and an absolute body weight of 0.4409±0,0070c g, a specific growth rate of 2.85±0,025d %, and a survival rate of 95,00±1,67b %. The water quality in this study was classified as optimal, with temperatures ranging from 25.9 to 27.1 °C, pH 6.3 to 6.4, and DO 5.43 to 6.58 mg/L.

Abstract

Penelitian ini menganalisis komunikasi krisis PT Indonesia Weda Bay Industrial Park (IWIP) dalam isu dugaan pencemaran lingkungan, krisis air bersih, ISPA, konflik lahan, dan menurunnya kepercayaan publik di Halmahera Tengah, Maluku Utara. Kasus ini penting dikaji karena krisis yang muncul tidak hanya berkaitan dengan persoalan teknis lingkungan, tetapi juga menyangkut reputasi organisasi, legitimasi industri nikel, dan relasi antara perusahaan, pemerintah, media, organisasi masyarakat sipil, serta masyarakat terdampak. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus. Data dikumpulkan melalui media monitoring terhadap korpus pemberitaan online periode 2022–2026, dokumen resmi perusahaan, laporan organisasi masyarakat sipil, artikel ilmiah, serta wawancara dengan Dinas Lingkungan Hidup Halmahera Tengah. Analisis dilakukan menggunakan Situational Crisis Communication Theory, Image Repair Theory, Crisis and Emergency Risk Communication, Framing Theory, Social Amplification of Risk Framework, Stakeholder Salience Theory, dan Legitimacy Theory. Hasil penelitian menunjukkan bahwa krisis IWIP berkembang sebagai krisis reputasi ekologis yang ditandai oleh pertarungan narasi antara pemberitaan media, laporan NGO, klarifikasi pemerintah daerah, dan respons perusahaan melalui bantahan, CSR, ESG, serta program lingkungan. Strategi komunikasi IWIP cenderung menggunakan pola denial, diminish, bolstering, dan corrective action. Efektivitas komunikasi tersebut masih menghadapi tantangan karena terdapat kesenjangan antara data teknis, persepsi risiko warga, dan kepercayaan publik. Penelitian ini menegaskan bahwa komunikasi krisis dalam industri ekstraktif memerlukan transparansi data, dialog partisipatif, empati terhadap warga terdampak, audit independen, serta media monitoring berkelanjutan. Kata kunci: komunikasi krisis, komunikasi risiko, IWIP, Sungai Sagea, reputasi organisasi, ESG, media monitoring. Abstract This study analyzes the crisis communication of PT Indonesia Weda Bay Industrial Park (IWIP) in relation to alleged environmental pollution, clean water crisis, acute respiratory infections, land conflicts, and declining public trust in Central Halmahera, North Maluku. This case is important because the crisis is not merely a technical environmental issue but also concerns organizational reputation, legitimacy of the nickel industry, and relations among corporations, government, media, civil society organizations, and affected communities. This research uses a qualitative case study approach. Data were collected through media monitoring of online news coverage from 2022 to 2026, corporate documents, civil society reports, scientific articles, and an interview with the Environmental Agency of Central Halmahera. The analysis applies Situational Crisis Communication Theory, Image Repair Theory, Crisis and Emergency Risk Communication, Framing Theory, Social Amplification of Risk Framework, Stakeholder Salience Theory, and Legitimacy Theory. The findings indicate that IWIP’s crisis has developed into an ecological reputation crisis marked by contested narratives among media reports, NGO findings, government clarification, and corporate responses through denial, CSR, ESG narratives, and environmental programs. IWIP’s communication strategies tend to involve denial, diminish, bolstering, and corrective action. Their effectiveness remains challenged by gaps between technical data, community risk perception, and public trust. This study argues that crisis communication in extractive industries requires data transparency, participatory dialogue, empathy toward affected communities, independent audits, and continuous media monitoring. Keywords: crisis communication, risk communication, IWIP, Sagea River, organizational reputation, ESG, media monitoring.

Abstract

Keberhasilan pembenihan ikan patin strain Pustina (Pangasianodon hypophthalmus) sangat bergantung pada ketersediaan benih yang berkualitas, khususnya pada fase larva yang memiliki tingkat mortalitas dan kanibalisme relatif tinggi. Salah satu faktor penentu keberhasilan pada fase ini adalah kualitas pakan. Larva ikan patin umumnya diberi pakan alami berupa Artemia sp. dan cacing sutra, kemudian dilanjutkan dengan pakan komersial (PF-0). Namun, strategi pemberian pakan tersebut belum sepenuhnya mampu mengoptimalkan pertumbuhan dan kelulushidupan larva. Oleh karena itu, diperlukan inovasi pakan melalui proses fermentasi serta penambahan bahan aditif alami yang berpotensi meningkatkan performa larva. Penelitian ini bertujuan untuk mengevaluasi efektivitas penambahan tepung kunyit (Curcuma longa Linn.) dalam pakan pasta terfermentasi terhadap pertumbuhan, kelulushidupan, dan tingkat kanibalisme larva ikan patin strain Pustina. Penelitian dilaksanakan selama 40 hari di Laboratorium Pembenihan dan Pemuliaan Ikan, Fakultas Perikanan dan Ilmu Kelautan, Universitas Riau. Penelitian disusun menggunakan rancangan acak lengkap (RAL) yang terdiri atas lima perlakuan dan tiga ulangan. Perlakuan yang digunakan meliputi P1 sebagai kontrol tanpa penambahan tepung kunyit (0,0 g kg−1 pakan), P2 (1,5 g kg−1 pakan), P3 (3,0 g kg−1 pakan), P4 (4,5 g kg−1 pakan), dan P5 (6,0 g kg−1 pakan). Hasil penelitian menunjukkan bahwa penambahan tepung kunyit memberikan pengaruh nyata (p<0,05) terhadap pertambahan bobot mutlak, panjang mutlak, laju pertumbuhan spesifik, serta kelulushidupan larva ikan patin. Perlakuan P5 memberikan hasil terbaik dengan pertambahan bobot mutlak sebesar 1,53 g, pertambahan panjang mutlak 6,06 cm, laju pertumbuhan spesifik 15,91% hari−1, dan kelulushidupan larva sebesar 86,22%. Perlakuan P5 jika dibandingkan dengan kontrol, hasilnya menunjukkan peningkatan pertambahan bobot sebesar 25,24%, pertambahan panjang 34,82%, laju pertumbuhan spesifik 3,66%, serta kelulushidupan sebesar 10,23%. Selama penelitian, kualitas air berada pada kisaran optimal, yaitu suhu 26,6–28,6°C, oksigen terlarut 5,7–6,8 mg L−1, dan pH 6,5–7,1. Tepung kunyit berpotensi dimanfaatkan sebagai bahan aditif pakan yang mudah diaplikasikan guna mendukung peningkatan produksi benih ikan patin strain Pustina.Striped catfish hatchery production of the Pustina strain (Pangasianodon hypophthalmus) is highly dependent on the availability of high-quality seed, particularly during the larval stage, which is characterized by relatively high mortality and cannibalism rates. One of the key factors determining success at this stage is feed quality. Striped catfish larvae are commonly fed natural diets such as Artemia sp. and tubifex worms, followed by commercial feed (PF-0). However, this feeding strategy has not yet fully optimized larval growth and survival. Therefore, feed innovation through fermentation and the addition of natural feed additives is required to improve larval performance. This study aimed to evaluate the effectiveness of turmeric (Curcuma longa Linn.) powder supplementation in fermented paste feed on growth, survival rate, and cannibalism level of striped catfish larvae. The experiment was conducted for 40 days at the Fish Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine Science, Universitas Riau, using a completely randomized design with five treatments and three replications, namely P1 (0.0 g kg−1), P2 (1.5 g kg−1), P3 (3.0 g kg−1), P4 (4.5 g kg−1), and P5 (6.0 g kg−1) turmeric powder supplementation in the feed. The results showed that turmeric powder supplementation had a significant effect (p<0.05) on absolute weight gain, absolute length gain, specific growth rate, and survival rate of striped catfish larvae. The best performance was obtained in treatment P5, with an absolute weight gain of 1.53 g, an absolute length gain of 6.06 cm, a specific growth rate of 15.91% day−1, and a survival rate of 86.22%. Compared with the control treatment (P1), P5 increased weight by 25.24%, length by 34.82%, specific growth rate by 3.66%, and survival rate by 10.23%. During the experimental period, water quality parameters remained within optimal ranges, with temperatures of 26.6–28.6°C, dissolved oxygen levels of 5.7–6.8 mg L−1, and pH values of 6.5–7.1. Turmeric powder has the potential to be used as a feed additive that is easy to apply and can support the sustainable improvement of Pustina strain striped catfish  fingerling production.

Abstract

A Muslim views that nature belongs to God and human beings must show that they are grateful by learning how to use and manage it well so that it can provide benefits to the mankind. Exploiting nature taught by Islam is based on the utilization of responsibility that provides benefits not only for its content but also its intact and sustainable opportunities to cultivate and for rehabilitation or to help speed up its recovery. Humans are required to have certain characters towards nature, which means dealing with nature by maintaining sustainability. Therefore, God gives cues to enable people to control themselves in exploitation of the natural resources which causes defection that can harm and even destroy human life. For that reason, Islam forbids destructing or harming the environment ranging from very small actions and trivial such as prohibiting throwing human faces under a fruit tree, in the river, on the road, or in the shelter areas. Prophet Muhammad (PBUH) is also very concerned about the preservation of wildlife, as described in the Hadith narrated by Abu Dawood. Even Prophet never reprimanded one of his companions during the Hijrah period to take the chicks out of the nest. Similarly, Islam cares about the environment created by God which human beings are mandated to maintain nature properly and responsibly. Keywords: Concept of Islam, the environment, education.Copyright © 2015 by Al-Ta'lim All right reserved
