Penelitian ini bertujuan untuk mengetahui pengaruh berbagai jenis kemasan terhadap Total Koloni Bakteri dan Total Koloni Bakteri Asam Laktat dari probiotik Lactobacillus salivarius yang terenkapsulasi arabinoxylan selama masa penyimpanan. Metode penelitian yang digunakan adalah metode eksperimen dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan kemasan (P0: tanpa kemasan, P1: aluminium foil, P2: kardus, P3: kombinasi aluminium foil dan kardus) dengan lima ulangan. Analisis data dilakukan menggunakan Analysis of Variance (ANOVA) dan dilanjutkan dengan menggunakan aplikasi SPSS 16 Uji Duncan Multiple Range Test (DMRT) jika terdapat pengaruh yang nyata. Hasil analisis statistik menunjukkan bahwa jenis kemasan tidak memberikan pengaruh nyata (P≥0,05) terhadap Total Koloni Bakteri, di mana jumlah populasi mikroba heterotrof pada seluruh perlakuan cenderung stabil dan seragam. Sebaliknya, jenis kemasan memberikan pengaruh yang nyata (P≤0,05) terhadap Total Koloni Bakteri Asam Laktat selama periode penyimpanan 30 hari. Jumlah Total Koloni Bakteri Asam Laktat tertinggi ditemukan pada kemasan kardus (P2) sebesar 1,5 x 105 CFU, sedangkan jumlah terendah terdapat pada kemasan aluminium foil (P1) sebesar 7,7 × 107 CFU. Karakteristik kemasan kardus yang porus diduga mampu menjaga keseimbangan difusi gas hasil metabolisme dan melindungi sel dari fluktuasi suhu secara optimal. Kesimpulan dari penelitian ini adalah jenis kemasan terbukti memengaruhi Total Koloni Bakteri Asam Laktat tetapi tidak memengaruhi Total Koloni Bakteri, dengan kemasan kardus sebagai media penyimpanan yang paling efektif.

The research method utilized an experimental approach with a Completely Randomized Design (CRD), consisting of four packaging treatments (P0: no packaging, P1: aluminum foil, P2: cardboard, P3: combination of aluminum foil and cardboard) with five replications. Data were analyzed using Analysis of Variance (ANOVA) and, if a significant effect was detected, further tested using the Duncan Multiple Range Test (DMRT) with the SPSS 16 application. Statistical analysis showed that the packaging type had no significant effect (P≥0,05) on Total Bacterial Colonies, where the heterotrophic microbial population across all treatments tended to be stable and uniform. Conversely, the packaging type significantly affected (P≤0,05) the Total Lactic Acid Bacteria Colonies during the 30-day storage period. The highest Total Lactic Acid Bacteria Colonies count was found in cardboard packaging (P2) at 1.5 x 105 CFU, while the lowest count was observed in aluminum foil packaging (P1) at 7,7 × 107 CFU. The porous characteristic of cardboard packaging is suggested to effectively maintain the balance of metabolic gas diffusion and optimally protect the cells from temperature fluctuations. In conclusion, the packaging type significantly influences the of Total Lactic Acid Bacteria Colonies but does not affect total bacterial colonies, with cardboard packaging being the most effective storage medium. Keywords: Lactobacillus salivarius, packaging, total bacterial colonies, lactic acid bacteria, encapsulation, packaging, arabinoxylan

Penggunaan bahan enkapsulasi merupakan salah satu upaya untuk meningkatkan stabilitas dan efektivitas probiotik Lactobacillus salivarius dalam memperbaiki kualitas telur puyuh. Tujuan utama penelitian ini adalah untuk mengkaji pengaruh berbagai jenis bahan enkapsulasi probiotik terhadap kadar protein dan kolesterol telur puyuh (Coturnix coturnix japonica). Penelitian ini menggunakan metode eksperimen dengan menerapkan Rancangan Acak Lengkap (RAL) yang terdiri atas 5 perlakuan dan 3 kali ulangan menggunakan 150 ekor puyuh petelur betina umur 5 minggu. Perlakuan meliputi pakan basal tanpa probiotik (P0), probiotik non-enkapsulasi (P1), probiotik terenkapsulasi maltodekstrin (P2), arabinoxylan (P3), dan kombinasi maltodekstrin–arabinoxylan (P4). Parameter yang diamati meliputi kadar protein telur dengan metode Kjeldahl dan kadar kolesterol telur menggunakan Gas Chromatography (GC). Data dianalisis menggunakan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Duncan apabila menunjukkan pengaruh nyata. Berdasarkan hasil penelitian, diketahui bahwa perlakuan tidak memberikan pengaruh yang nyata (P>0,05) terhadap kadar protein telur puyuh, tetapi berpengaruh nyata (P<0,05) terhadap kadar kolesterol telur. Perlakuan probiotik yang dienkapsulasi menggunakan arabinoxylan menghasilkan kadar protein tertinggi (13,58%) dan kadar kolesterol terendah (603,33 mg/100 g). Dengan demikian, penggunaan arabinoxylan sebagai bahan enkapsulasi probiotik Lactobacillus salivarius berpotensi meningkatkan efektivitas probiotik dalam menghasilkan telur puyuh dengan kadar kolesterol yang lebih rendah tanpa menurunkan kadar protein telur.Kata kunci: Lactobacillus salivarius, enkapsulasi, maltodekstrin, arabinoxylan, protein telur, kolesterol telur.EFFECT OF VARIOUS ENCAPSULATION MATERIALS OF LACTOBACILLUS SALIVARIUS PROBIOTICS ON THE PROTEIN AND CHOLESTEROL CONTENTS OF JAPANESE QUAIL (Coturnix Coturnix Japonica) EGGSAbstractThe use of encapsulation materials is one approach to improving the stability and effectiveness of Lactobacillus salivarius probiotics in enhancing quail egg quality. The main objective of this study was to investigate the effects of different probiotic encapsulation materials on the protein and cholesterol contents of quail eggs (Coturnix coturnix japonica). This study employed an experimental method using a Completely Randomized Design (CRD) consisting of five treatments and three replications, involving 150 female laying quails aged five weeks. The treatments consisted of basal feed without probiotics (P0), non-encapsulated probiotics (P1), probiotics encapsulated with maltodextrin (P2), probiotics encapsulated with arabinoxylan (P3), and probiotics encapsulated with a combination of maltodextrin and arabinoxylan (P4). The parameters observed were egg protein content analyzed using the Kjeldahl method and egg cholesterol content analyzed using Gas Chromatography (GC). The data were analyzed using Analysis of Variance (ANOVA), followed by Duncan’s multiple range test when a significant effect was observed. The results showed that the treatments had no significant effect (P>0.05) on egg protein content but had a significant effect (P<0.05) on egg cholesterol content. The P3 treatment, using arabinoxylan-encapsulated probiotics, resulted in the highest protein content (13.58%) and the lowest cholesterol content (603.33 mg/100 g). Therefore, the use of arabinoxylan as an encapsulation material for Lactobacillus salivarius probiotics has the potential to improve probiotic effectiveness in producing quail eggs with lower cholesterol content without reducing egg protein content.Keywords: Lactobacillus salivarius, encapsulation, arabinoxylan, maltodextrin, egg protein, egg cholesterol.

Penelitian ini bertujuan “untuk mengevaluasi pengaruh penambahan berbagai konsentrasi inokulum Aspergillus niger pada fermentasi tongkol jagung terhadap kandungan protein kasar dan serat kasar.” Penelitian ini dilangsungkan di Teaching Farm dan Laboratorium Terpadu Fakultas Peternakan Universitas Islam Malang pada Juni 2026. Rancangan penelitian menggunakan 4 perlakuan fermentasi dengan konsentrasi Aspergillus niger berbeda: P0 = kontrol, P1, P2, dan P3 = 8 ml inokulum dengan penambahan urea 10 g dan molases 25 ml. Temuan analisis ragam menjabarkan bahwa penambahan Aspergillus niger berpengaruh sangat nyata (P<0,01) terhadap protein kasar dan serat kasar. Kadar protein kasar tertinggi diperoleh pada perlakuan P3 sebesar 28,01 ± 2,4%, meningkat dibanding P0 sebesar 14,88 ± 9,1%. Kadar serat kasar terendah diperoleh pada perlakuan P2 sebesar 24,29 ± 2,59%, sedangkan P3 sebesar 41,07 ± 5,66%. Peningkatan protein disebabkan oleh pertumbuhan miselium A. niger yang kaya protein, sedangkan penurunan serat terjadi akibat aktivitas enzim selulase dan hemiselulase. Kesimpulan, konsentrasi 8 ml inokulum A. niger optimal untuk meningkatkan protein kasar tongkol jagung menjadi 28,01%, namun untuk menurunkan serat kasar perlakuan P2 lebih efektif. Fermentasi A. niger berpotensi meningkatkan nilai gizi tongkol jagung sebagai pakan alternatif ruminansia.Kata Kunci: Aspergillus niger, fermentasi, tongkol jagung, protein kasar, serat kasar EFFECT OF ASPERGILLUS NIGER UTILIZATION ON MAIZE COB FERMENTATION ON PROTEIN AND CRUDE FIBER CONTENTAbstractThis study aimed “to evaluate the effect of adding various concentrations of Aspergillus niger inoculum on corn cob fermentation on crude protein and crude fiber content.” The research was conducted at the Teaching Farm and Integrated Laboratory of the Faculty of Animal Husbandry, Universitas Islam Malang in June 2026. The study used 4 fermentation treatments with different A. niger concentrations: P0 = control, P1, P2, and P3 = 8 ml inoculum with the addition of 10 g urea and 25 ml molasses. Analysis of variance showed that the addition of A. niger had a very significant effect (P<0.01) on crude protein and crude fiber. The highest crude protein content was obtained in treatment P3 at 28.01 ± 2.4%, an increase compared to P0 at 14.88 ± 9.1%. The lowest crude fiber content was obtained in treatment P2 at 24.29 ± 2.59%, while P3 was 41.07 ± 5.66%. The increase in protein was due to the growth of A. niger mycelium which is rich in protein, while the decrease in fiber was due to the activity of cellulase and hemicellulase enzymes. In conclusion, a concentration of 8 ml A. niger inoculum was optimal for increasing the crude protein of corn cobs to 28.01%, but for reducing crude fiber, treatment P2 was more effective. Fermentation with A. niger has the potential to improve the nutritional value of corn cobs as an alternative feed for ruminants.Keywords: Aspergillus niger, fermentation, corn cob, crude protein, crude fiber.
