Abstract

The objective of this study was to determine the inhibitory of earthworm (Lumbricus rubellus) extract (ECT) and encapsulated earthworm extract (ECT-t) as poultry feed additive against some pathogenic bacteria. Earthwom extract was prepared by dekokta method with water at 90 ºC then encapsulated by spray drying with maltodextrin as filler. In vitro antibacterial activity was performed using dilution method against Escherichia coli, Staphylococcus aureus, Salmonella pullorum, and Pseudomonas aeruginosa. The optical density results showed that started from ECT level 0.26% inhibited (PP. aeruginosa and S. aureus, while ECT level 0.52% inhibited (PE. coli and S. pullorum along with the increased levels of concentration. The percentage of growth showed that ECT level 1.04% had inhibitory (PE. coli and P. aeruginosa, while ECT level 0.52% showed antibacterial activity (PS. aureus. The result showed that S. aureus was the most sensitive bacterium to earthworms extract. ECT-t level 0.78% and 1.04% measured by spectrophotometer showed inhibitory (PP. aeruginosa and S. pullorum respectively. While ECT-t level 0.26% measured by spread plate count method showed inhibitory activity against P. aeruginosa. LD50 of E. coli and P. aeruginosa were found at ECT level 1.04%, while LD50 of S. aureus was found at level 0.52%. LD50 of P. aeruginosa was found at ECT-t level 0.52%. There were no antibacterial action (P>0.05) of ECT and ECT-t against S. pullorum.

Abstract

An experiment was conducted to determine the efficacy of bio additive administration (a mixture of Lumbricus rubellus extract, Morinda citrifolia leaves extract and lactic acid bacteria), probiotic, and antibiotic to the performance and meat quality of broiler infected with Avian Pathogenic Escherichia coli (APEC). In this study, 140 Jumbo 747 unsexed one-day old chicks were distributed randomly into 20 units of cages, each filled with 7 broilers. Twenty cages were assigned into 5 treatment groups, each treatment in 4 equal replicates. The treatments were as follows: A= E. coli infection (positive control), B= E. coli infection + bio additive, C= E. coli infection + probiotic, D= E. coli infection + antibiotic, E= No E. coli infection (negative control). A commercial corn-soybean-based broiler diet was formulated as the basal diets. The experimental period was 35 d and at 21st d of age the broilers were infected with E. coli except the E treatment. The result showed that bio additive administration (B) increased the final body weight (1,659.52 g) and body weight gain (1,616.81 g) and resulted in less FCR (1.87) among other treatments. The lowest mortality rate was recorded in B treatment (3.57%) and D treatment (3.57%). Probiotic (C treatment) and antibiotic (D treatment) decreased (P < 0.05) meat pH and tenderness compared to other treatments. Meanwhile bio additive administration did not affect the meat quality (pH, cooking loss, water-holding capacity, tenderness, and fat) compared to positive and negative controls. The lowest meat cholesterol content was observed in B treatment (54.02 mg/100 g). It is concluded that bio additive administration on broiler infected with E. coli increased the broiler performance and decreased the meat cholesterol compared to other treatments.

Abstract

Dalam beberapa kurun waktu belakangan ini, perkembangan teknologi berkembang dengan sangat cepat, terlebih untuk media sosial. Salah satu media sosial yang paling banyak digunakan sampai saat ini adalah Instagram dan sebagian besar digunakan sebagai media promosi dari banyak pemilik usaha bisnis, baik dari perusahaan besar maupun kecil. Salah satu usaha yang menggunakan Instagram adalah Koin Design Yogyakarta. Namun, bisnis Koin Design Yogyakarta ini masih belum optimal dalam pengelolaan media sosialnya, baik dari segi desain dan konsistensi. Hal ini disebabkan oleh kemampuan SDM pada bagian desain dan editing untuk keperluan media sosial yang masih kurang. Solusi untuk mengatasi masalah tersebut adalah dengan melakukan pelatihan dalam penggunaan media sosial untuk promosi dan penyediaan awal foto katalog, desain dan editing untuk media sosial Koin Design Yogyakarta. Pelatihan dilaksanakan sebanyak dua sesi yaitu sesi pertama untuk pelatihan pengaplikasian dan sesi dua untuk pendampingan. Dari pelaksanaan pelatihan pada Koin Design Yogyakarta mempublikasikan tiga unggahan pada feeds Instagram. Hasil data Insights Instagram Koin Design Yogyakarta terlihat ada kenaikan setelah diadakan pelatihan dari akun yang dicapai dan akun yang aktif dalam berinteraksi.
