Profil Vertikal Bahan Organik Dasar Perairan dengan Latar Belakang Pemanfaatan Berbeda di Rawa Pening

Sedimentasi di Rawa Pening berlangsung secara intensif dan selalu meningkat sehingga menyebabkan pendangkalan akibat pertumbuhan Eceng Gondok (Eichhornia crassipes) yang tidak terkendali. Penumpukan bahan organik akibat Eceng Gondok di dasar perairan perlu diteliti pengaruhnya bagi lingkungan perairan. Penelitian ini bertujuan untuk mengetahui profil kandungan bahan organik secara vertikal pada zonasi pendangkalan di kawasan tutupan Eceng Gondok dan perairan terbuka serta untuk mengetahui hubungan potensi bahan organik dengan sediaan nutrien nitrogen dan fosfor. Penelitian ini menggunakan metode deskriptif dan metode sampling menggunakan purposive sampling. Lokasi penelitian terdiri dari 2 stasiun yaitu kawasan tutupan Eceng Gondok dan perairan terbuka. Data yang diukur meliputi bahan organik, N Total, P Total, pH tanah, tekstur tanah, kedalaman kecerahan, arus, suhu, dan DO. Hasil penelitian menunjukkan bahwa kandungan bahan organik, N Total dan P Total pada semua segmen tidak memiliki pola. Bahan organik tergolong sangat tinggi dengan kisaran 61,99% - 74,82%. P Total tergolong tinggi sedangkan N Total tergolong rendah sampai sedang. Kontribusi nutrien ini tergolong rendah sampai sedang terhadap perairan akibat DO dan pH yang rendah

Performance, Egg Quality, Bone Health, and Immunity Assessments of Lohmann Laying Hens Supplemented with Vitamin D3 in the Diet

Bone health in laying hens is associated with production performance and physical egg quality. This study aimed to evaluate the effects of a diet supplemented with Nutricell Eggstra (vitamin D3 enriched with canthaxanthin) on the production performance, egg quality, bone mineral, and immunity of laying hens. Herein, 150 Lohmann laying hens were divided into three treatments with five replicates. The treatment diets were: T1= diet without Nutricell Eggstra supplementation (control), T2= diet supplemented with 1.00 kg/ton Nutricell Eggstra, and T3= diet supplemented with 1.50 kg/ton Nutricell Eggstra. Compared to the control diet, supplementation of Nutricell Eggstra at doses of 1.00 kg/ton and 1.50 kg/ton significantly increased (p<0.05) hen day production, egg mass, egg index, yolk index, albumen weight, yolk color, eggshell thickness, eggshell strength, vitamin D3 content in egg yolk, heterophil, and heterophil/lymphocyte ratio. Supplementation of Nutricell Eggstra at the studied doses significantly decreased (p<0.05) the feed conversion ratio, yolk weight, eggshell porosity, and lymphocyte content. Nutricell Eggstra supplementation did not affect feed consumption, egg weight, albumen index, albumen weight, eggshell weight, Haugh unit, and tibia bone minerals. In conclusion, supplementation of 1.00 kg/ton Nutricell Eggstra yielded the best performance for Lohmann laying hens aged 36-39 weeks, while supplementation of 1.50 kg/ton Nutricell Eggstra produced the best quality eggs

Proceedings of the 3rd International Conference on Community Engagement and Education for Sustainable Development

This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
