Perendaman Rumput Laut Turbinaria murayana dalam Aliran Air Sungai sebelum digunakan sebagai Bahan Pakan Unggas

Abstract

Penelitian ini bertujuan untuk mengurangi kandungan garam dan meningkatkan kandungan nutrisi rumput laut Turbinaria murayana yang direndam dalam aliran air sungai sebelum digunakan sebagai bahan pakan ternak unggas. Materi yang digunakan yaitu rumput laut jenis Turbinaria murayana yang diambil dari Pantai Sungai Nipah Kabupaten Pesisir Selatan secara acak pada 5 lokasi yang berbeda, kemudian dikomposit sebagai sampel penelitian. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan, masing-masing perlakuan diulang 5 kali. Perlakuan berupa lama perendaman dalam aliran air sungai yaitu 0, 1, 3, 5, dan 7 jam. Hasil penelitian menunjukkan bahwa perendaman rumput laut Turbinaria murayana dalam aliran air sungai berpengaruh sangat nyata (P≤0,01) terhadap kadar garam, serat kasar, protein kasar, dan bahan kering. Penurunan kadar garam terbaik terdapat pada perlakuan perendaman selama 3 jam dengan penurunan kadar garam dari 14,4% menjadi 0,76% dan mengandung 13,75% serat kasar, 6,36% protein kasar, serta 17,5% bahan kering.

Reducing Salt (NaCl) Content of Seaweed (Turbinaria decurrens) before Being Used as Poultry Feed Ingredients

“…decurrens seaweed from Sungai Nipah Coast, Pesisir Selatan Regency, West Sumatra was taken from 5 different locations, then combined to be used as research samples. These samples were taken and brought to a location or place for immersion in running water at Irrigation canal, Gunung Nago with a depth of 1.65 m and a water discharge of 0.0610 m3/s (Reski et al, 2020). The seaweed obtained, before being immersed in running water, was washed and cleaned first of the remnants of sea sand, small corals attached to the seaweed, then soaked in running water according to the immersion treatment, i.e.…”

“…According to Dewi et al, (2018) the long treatment of immersion Sargassum binderi type of seaweed in running water can reduce the dry matter content compared to without immersing. Furthermore, Reski et al, (2020) also reported that the immersion of Turbinaria murayana, brown seaweed, in running water with different immersion duration for use as broiler feed material caused a decrease in the dry matter content. Immersion of Turbinaria murayana seaweed in running water with different durations of immersion is best for the immersion for 3 hours (Reski et al, 2020).…”

“…The decrease in salt content (NaCl) of T. decurrens seaweed in each immersion duration was caused by the bonding and attraction of water during immersion which can attract and dissolve the salt contained in seaweed, as water is an organic solvent that can dissolve ions such as salt (NaCl). Reski et al, (2020) reported that soaking seaweed in running water can reduce the salt content of the Turbinaria murayana seaweed, because water is an excellent solvent in dissolving ions such as salt and water can also bind and clean sand attached to the seaweed. According to Dewi et al, (2018), soaking Sargassum binderi in running water for 15 hours is the best immersion duration in reducing the NaCl content of the seaweed before being used in laying hens rations.…”

“…Crude protein increases, because crude protein is part of organic matter. According to Reski et al, (2020) that the immersion of Turbinaria murayana seaweed in running water with different immersion duration can increase the crude protein content of the material. Furthermore, Dewi et al, (2018) also reported that the immersion treatment in running water using Sargassum binderi type seaweed with different immersing duration can also increase the crude protein content of the material.…”

“…Efforts to reduce NaCl content of feeds might be performed through immersion in running water. According to Reski et al (2020), the immersion of seaweed Turbinaria murayana in running water for 3 hours can reduce the salt content of the seaweed from 14.4% to 0.76% NaCl. Previously, Dewi et al, (2018) also reported that soaking seaweed Sargassum binderi in running water for 15 hours was the best immersion treatment in reducing salt (NaCl) content before being used as feed ingredients in laying hen's rations.…”
