Honey also contains potassium which triggers steroid hormones in protein metabolism, brings glucose into cells and stimulates the hypothalamus, so that it can trigger appetite in animals and influence the level of consumption and feed efficiency. This study aims to determine the best type of honey in nile tilapia larvae for consumption and feed efficiency. Honey used in this study were; forest honey (from Bontocani, Selayar, Sumbawa) and livestock honey with a dose of 0.2% of the total volume of solvents, through the immersion method. The seven days old nile tilapia larvae were immersed in the treatments for 24 hours, then they were reared for 60 days.

The aim of testing co-firing of sugarcane bagasse biomass is to determine the effect of co-firing on the reliability and main parameters of coal-fired power plants and to obtain an overview of the feasibility of implementing co-firing which includes aspects of operational technical evaluation, production cost evaluation and environmental evaluation. The biomass effectiveness test was carried out at PLTU Rembang, with test variables of 100% coal, co-firing test of 1.25% and 2.5% sugarcane bagasse biomass with a maximum operational load of 315 MW for 6 hours. The results of data analysis were carried out descriptively. The tested sugarcane bagasse biomass had a calorific value of 2947 kCal/kg. Meanwhile, the coal used in PLTU Rembang has a calorific value of 4286 kcal/kg. The SO2 emission test results decreased in the Co-firing test of 1.25% sugarcane bagasse and increased in the Co-firing test of 2.5% sugarcane bagasse compared to the 100% coal test, while the NOx emission test results produced during the co-firing test firing 1.25% and 2.5% sugarcane bagasse biomass has a lower value than using 100% coal. The cost of co-firing electricity production from sugarcane bagasse biomass is 1.25% and 2.5% cheaper than the cost of producing 100% coal electricity. To reduce electricity production costs, the sugarcane bagasse biomass co-firing scheme needs to be emphasized by referring to HPT determination in accordance with PLN Perdir No.0004/DIR/2022, so that co-firing electricity production costs can be more economical.</em></p> Riris Destalia Enny Aryanny Copyright (c) 2024 Riris Destalia, Enny Aryanny https://creativecommons.org/licenses/by/4.0 2024-02-28 2024-02-28 3 1 32 43 10.55123/insologi.v3i1.3041 Kapasitas Resin Immobilized Photocatalyst-Zno untuk Menyisihkan Total Nitrogen pada Limbah Dalam Reaktor Fotokatalis secara Continue https://journal.literasisains.id/index.php/insologi/article/view/3046 <p><em>Nitrogen is one of the organic compounds contained in liquid waste produced by the tofu industry. In aquatic ecosystems, excessive amount of nitrogen can lead to eutrophication and increase the amount of ammonia, nitrate and nitrite which are poisonous to humans, livestock and wildlife. In order to deal with the issues, photo-catalyst technology is employed to process the organic liquid waste by converting themintoCO_2 and water which are relatively safer. Throughout the process, it requires a medium like resin immobilized photocatalyst-ZnO (RIP-ZnO) to absorb the pollutants. Based on the aforementioned background, this study aims to analyze the impact of RIP-ZnO capacity in reducing the total Nitrogen parameter. The analysis of total Ninthisstudy was conducted by using the Kjeldahl method consisting of three processes, namely destruction, distillation and titration. The research began with the process of making reactor and RIP-ZnO. Subsequently, once the total N concentration is known, the process of resin capacity calculation is continued. As a result, the research findings indicate that the highest resin capacity of 1.14542 reduces the total Nby 33%, while the lowest one of 0.00012 decreases it by 59%. In other words, the resin capacity has an impact on the percentage of total N removal. In conclusion, the lower the resin capacity is, the higher the removal percentage is, and vice versa.</em></p> Nuriadin Kazal Firra Rosariawari Okik Hendriyanto Cahyonugroho Aussie Amalia Copyright (c) 2024 Nuriadin Kazal, Firra Rosariawari, Okik Hendriyanto Cahyonugroho, Aussie Amalia https://creativecommons.org/licenses/by/4.0 2024-02-28 2024-02-28 3 1 44 51 10.55123/insologi.v3i1.3046 Analisis Faktor Resiko Mortalitas Covid 19 https://journal.literasisains.id/index.php/insologi/article/view/2690 <p><em>Medical records are a source of data for hospitals that can be processed into statistics.

In response to this global challenge, seaweed farming has emerged as a promising remedy. Leveraging their remarkable growth rates and carbon sequestration abilities, seaweeds offer a viable solution to counteract the acidifying effects of elevated carbon dioxide levels in the oceans. Through photosynthesis, seaweeds actively absorb carbon dioxide from seawater, thereby mitigating acidity and fostering improved water quality. The potential of seaweed farms extends beyond mere carbon sequestration. These farms play a pivotal role in habitat creation, absorb nitrogen and phosphorus nutrients, and contribute to enhanced biodiversity. The cultivation of seaweed not only addresses the immediate concern of ocean acidification but also provides a holistic ecological approach with far-reaching benefits. As a sustainable and scalable strategy, seaweed farming exemplifies an innovative and multifaceted solution to the complex challenges posed by anthropogenic impacts on the oceans, underlining the importance of nature-based interventions in preserving the health and balance of marine ecosystems.</em></p> Moch Altof Maulana Firra Rosariawari Copyright (c) 2024 Moch Altof Maulana, Firra Rosariawari https://creativecommons.org/licenses/by/4.0 2024-02-28 2024-02-28 3 1 68 75 10.55123/insologi.v3i1.3072 Autekologi sebagai Tahapan Awal Rehabilitasi Ekosistem Mangrove Cuku Nyinyi, Desa Sidodadi, Kecamatan Teluk Pandan, Pesawaran https://journal.literasisains.id/index.php/insologi/article/view/3144 <p><em>The presence of mangroves tends to decrease every year, one of the reasons being degradation due to land cultivation.
