This study aims to reduce the salt content in Turbinaria murayana seaweed before its incorporation into poultry feed by soaking it in fresh water at a 1:50 w/v ratio. The experimental design follows a completely randomized design with five treatments and four replications. The treatments involved soaking durations of 1, 2, 3, 4, and 5 days in freshwater. Data were analyzed using Analysis of Variance (ANOVA), and treatment differences were assessed using Duncan's Multiple Range Test. The results indicated that different soaking durations in freshwater effectively reduced the salt content and increased the dry matter and organic matter percentages of Turbinaria murayana seaweed. A soaking duration of 2 days is particularly effective, resulting in a salt content of 0.61%, a salt reduction percentage of 95.79%, a moisture content of 12.86%, a dry matter content of 87.14%, and an organic matter content of 71.13%.

This study evaluated the effect of different mixing ratios of Turbinaria murayana seaweed meal and tuna fish waste meal as alternative protein sources in poultry feed. The research was conducted using an experimental method arranged in a completely randomised design (CRD) with five treatments and four replications. The treatments consisted of different mixing ratios of Turbinaria murayana seaweed meal and tuna fish waste meal, namely 95:5%, 90:10%, 85:15%, 80:20%, and 75:25%. Data were analysed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test to determine significant differences among treatments. The results showed that varying the mixing ratios had no significant effect (P>0.05) on moisture content, organic matter, crude fiber, crude fat, and calcium levels, but significantly affected (P<0.05) crude protein and phosphorus contents. The 85:15% mixture produced the best nutritional composition as a protein source for poultry feed, with the following nutrient contents: moisture 6.73%, organic matter 82.33%, crude fiber 8.58%, crude protein 31.11%, crude fat 15.35%, calcium 4.10%, and phosphorus 0.30%.

This study aimed to evaluate the effect of different extraction methods on the quality of alginate derived from Turbinaria murayana seaweed as a poultry feed additive. An experimental approach was employed using a completely randomised design (CRD) consisting of three treatments and six replications. The treatments involved three different extraction methods: acid, alkaline, and calcium pathways. The data were analysed using analysis of variance (ANOVA), and significant differences among treatments were further examined using Duncan’s Multiple Range Test. The results indicated that the extraction method had a highly significant effect (P<0.01) on alginate dry matter content and purity, while it had no significant effect (P>0.05) on alginate pH. Among the tested methods, the acid extraction pathway produced the highest quality alginate, meeting the quality standards set by the Food Chemicals Codex (FCC, 2004), with a dry matter content of 86.57%, a pH value of 9.17, and alginate purity of 36.28%.

Penelitian ini bertujuan untuk mendapatkan dosis Natrium Bikarbonat dan durasi penyimpanan bahan terbaik untuk menurunkan kandungan lemak kasar usus broiler. Penelitian menggunakan metode Rancangan Acak Lengkap dua faktor (RAL Faktorial). Faktor pertama adalah dosis Natrium Bikarbonat (A1= 0,8%, A2= 1,6%, A3= 3,2%), faktor kedua adalah durasi penyimpanan usus broiler yang dicampur Natrium Bikarbonat (B1= 6 jam, B2= 12 jam, B3= 24 jam). Peubah yang diamati adalah persentase rendemen, kandungan lemak kasar dan protein kasar. Hasil analisis keragaman menunjukkan Interaksi faktor pada persentase rendemen memberikan pengaruh berbeda sangat nyata (P<0,01) dengan rataan 55,45-90,84. Interaksi faktor memberikan pengaruh berbeda sangat nyata (P<0,01) terhadap penurunan kandungan lemak kasar dengan rataan 12,24-14,42%. Interaksi faktor pada kandungan protein kasar memberikan pengaruh berbeda tidak nyata (P>0,05) dengan rataan 55,56-62,29%. Kesimpulan hasil penelitian adalah perlakuan A3B1 (konsentrasi 3,2% dan durasi perendaman 6 jam) merupakan kombinasi terbaik menurunkan kandungan lemak kasar usus broiler.

This program was implemented in the Serumpun Livestock Group at Sungai Nipah Beach, Pesisir Selatan Regency, West Sumatra Province. The activity aimed to introduce the processing method of brown seaweed (Turbinaria murayana) before its incorporation into the diet of the Kampung Unggul Balitbangtan chicken (KUB). The methods employed included educational outreach, demonstrations, and hands-on training sessions. The outreach component covered the potential of Turbinaria murayana as an alternative feed ingredient and the processing stages from harvesting to ready-to-use feed. The training sessions demonstrated processing techniques, including freshwater soaking, sun-drying, and mechanical grinding. This activity was attended by 20 participants from the livestock group, consisting of 15 women and five men. The results showed an 85% improvement in participants' knowledge and skills in utilizing and processing Turbinaria murayana as a feed ingredient for KUB chickens. Farmers gained a better understanding of the nutritional content and potential of Turbinaria murayana, as well as effective processing methods to optimize its use in feed formulations. In conclusion, the program successfully enhanced farmers' understanding and practical skills in utilizing Turbinaria murayana seaweed as a feed ingredient for KUB chickens. It also reduced feed costs and supported the development of poultry feeds that were more economical than conventional ingredients such as ground corn, rice bran, and fish meal.
