“…Figure 1 shows that there is a change in the color and texture of the coconut testa on day 4, which indicates that mold growth is at the end of the log phase to the beginning of the stationary phase. According to (Endrawati & Kusumaningtyas, 2018), a mold of R. oryzae is one of the filamentous fungi that can be used as a source of probiotics in the bioconversion process because it is able to convert proteins into bioactive peptides as antimicrobials and antibiotics. In the bioconversion process, chemical changes occur that change the substrate which included the nutritional content of proximate results, amino acids and fatty acids as a medium for growing microorganisms into useful organic products (Table 2).…”

The nutritional content that is balanced and in accordance with the needs of fish will be utilized by fish as a source of energy used for growth. The used of feed alternative from coconut testa bioconversion has been investigated for its effect on the growth performance of red tilapia stadium fingerling. The chemical composition of coconut testa, survival rate and water quality (temperature, pH and dissolved oxygen) were analysed descriptively. The experiment was carried out experimentally using a Completely Randomized Design (CRD), which consisted of four levels of using coconut testa bioconversion by Rhizopus oryzae in feed (0%, 5%, 10%, 15%, and 20%). The performance parameters measured consisted of Average daily gain, feed efficiency, and protein efficiency ratio. Data were analyzed using the Analysis of Variance (ANOVA) with a 95% confidence level, and Duncan's multiple distance test. The chemichal change, survival rate. The study showed that the bioconversion of R. oryzae coconut testa up to 20% in the feed formulation could provide the performance of red tilapia fry, with the highest value obtained at the use of 15% with an average feed efficiency of 42.43 ± 0.71.

“…The crude fiber content in fish feed is a limiting factor because it can interfere with the digestibility of feed in the digestive system (Józefiak et al, 2018). Mold is a microorganism capable of using cellulose as a carbon source for its growth (Endrawati & Kusumaningtyas, 2018).…”

“…Kapang Rhizopus termasuk diantara mikroorganisme yang banyak digunakan dalam pengolahan pangan maupun pakan. Fermentasi menggunakan Rhizopus diketahui meningkatkan nilai nutrisi bahan pangan (Huang et al 2019) dan pakan (Endrawati and Kusumaningtyas 2017). Biomassa Rhizopus juga memiliki kandungan protein hingga 50% sehingga berpotensi sebagai sumber protein alternatif untuk pangan (Lennartsson et al 2018) maupun pakan (Santos et al 2016;Souza Filho et al 2017;Asadollahzadeh et al 2018;Souza Filho et al 2018).…”

Solid fermentation using the mold Rhizopus has been used as an alternative method to improve the physical quality of fish feed, namely stability in water and floatability. Although the fermented fish feed produced had been shown previously to have better stability in water and floatability, the effect of the fermentation on the fish feed nutrition has not yet been known. This study aimed to determine the effect of solid fermentation using the mold Rhizopus sp. on the nutrient content of the fermented feed. In addition, the effect of adding tapioca as much as 0, 1, 2, 3, and 4 g on the dry weight loss and density of the fermented feed was investigated. The results showed that the fermented feed contained higher levels of ash and protein compared to the feed without fermentation. The addition of tapioca up to 4 g had no significat effect (p>0.01) on the dry weight loss of the fermented feed, but tended to increase its density compared to those without tapioca addition. ABSTRAKFermentasi padat menggunakan kapang Rhizopus telah digunakan sebagai metode alternatif untuk memperbaiki kualitas fisik pakan ikan, yakni stabilitas dalam air dan daya apung. Meskipun pakan ikan fermentasi yang dihasilkan sebelumnya sudah dibuktikan memiliki stabilitas dalam air dan daya apung yang lebih baik, namun pengaruh fermentasi terhadap nutrisi pakan ikan tersebut belumlah diketahui. Penelitian ini bertujuan mengetahui pengaruh fermentasi padat menggunakan kapang Rhizopus sp. terhadap kandungan nutrisi pakan fermentasi, dan pengaruh penambahan tapioka sebanyak 0, 1, 2, 3, dan 4 g terhadap kehilangan berat kering dan mass jenis pakan hasil fermentasi. Hasilnya menunjukkan bahwa pakan fermentasi mengandung kadar abu dan protein lebih tinggi dibandingkan pakan tanpa difermentasi. Penambahan tapioka hingga 4 g tidak berpengaruh nyata (p>0,01) pada kehilangan berat kering pakan fermentasi, namun cenderung meningkatkan massa jenisnya dibandingkan tanpa penambahan tapioka.

Exophytic fungus diversity plays an important role in controlling pathogens that cause diseases, especially sugar-apple fruit rot. The greater the diversity, the more stable it is in the ecosystem, and the more opportunities that inhibit pathogens. The results showed that the exophytic fungi found in leaves, fruit and twigs were Aspergillus sp. A. niger, Fusarium sp., Mycelia sterilia, Neurospora sp., and Rhizopus sp. The diversity index of exophytic fungi was 2.374 with a dominance index of 0.8667. It indicates that the condition of the community structure is more stable with good categories. The dominance index approaches 1 means that there was a dominating fungus, namely A. niger fungus as much as 18 × 10 3 cfu. The inhibitory effect of exophytic fungi on Lasiodiplodia theobromae in vitro was found to be lower in Aspergillus sp. amounting to 65.68 ± 0.82 and it was higher in Rhizopus sp. amounting to 82.92 ± 0.50%.
