Tanaman pala merupakan tanaman khas Indonesia sering dimanfaatkan masyarakat sebagai bumbu masak dan manisan khususnya bagian daging buahnya. Namun seiring kemajuan teknologi, pala banyak dikembangkan sebagai obat herbal yang berpotensi sebagai antibakteri seperti Escherichia coli. Penelitian ini bertujuan untuk mengetahui potensi antibakteri ekstrak etil asetat daging buah dan daun pala terhadap Escherichia coli Sampel yang digunakan yaitu buah dan daun pala dengan teknik sampling yaitu purposive. Metode yang digunakan yaitu Kirby Bauer dan variasi ekstrak etil asetat daging buah dan daun pala yang digunakan yaitu 60%-100%. Hasil pengujian menunjukkan bahwa ekstrak etil asetat daging buah pala memiliki aktivitas antibakteri 1,5 kali lebih tinggi dibandingkan dengan bagian daun. Abstrak Info Artikel ANTIBACTERIAL ACTIVITY OF FLASH AND LEAD OF NUTMEG (MYRISTICA FRAGRANS) TO ESCHERICHIA COLINutmeg plant is a typical Indonesian plant that is often used as a condiment of cooking and confectionery, especially the flesh of the fruit. But as advances in technology, nutmeg is widely developed as a potent antibacterial herb as Escherichia coli. The aims of this study is to compare the antibacterial sensitivity of ethyl acetate extract of flesh and nutmeg leaves to Escherichia coli Samples used are fruit and nutmeg leaves with sampling technique is purposive. The method used is Kirby Bauer and the variation of ethyl acetate extract of the flesh and nutmeg leaves used is 60% -100%. The results showed that antibacterial of an ethyl acetate extract of flesh was 1,5 higher than nutmeg leaves. Abstract ©2018, Poltekkes Kemenkes PontianakAlamat korespondensi :
Indonesian local ducks are commonly raised for egg production purposes. However, the performances of these ducks are still variable and must be improved. This study investigated the effects of turmeric, curcuma, and probiotic supplementations on the egg production and quality of Indonesian local ducks, emphasizing the eggs' fatty acid profile. Two hundred female local ducks aged 16 weeks were randomly allotted to four dietary treatments with five replicates of 10 birds. The ducks were fed a corn and rice bran-based diet containing different supplements, i.e., a diet without supplementation as the control diet, a diet supplemented with turmeric at the level of 4%, a diet supplemented with curcuma at the level of 4%, and a diet supplemented with starbio probiotics at the level of 2%. The measured data were analyzed using analysis of variance using the 13 Systat program and continued with Duncan's Multiple Range Test. Turmeric supplementation increased egg production compared with the control, and the duck fed probiotics consumed more feed than the control. Curcuma supplementation generated the lowest feed consumption, egg production, and physical egg quality than the other treatments (p<0.05). The probiotics supplementation enhanced the blood high-density lipoprotein concentration (p<0.05). Turmeric, curcuma, and probiotics supplementations generate variable responses in egg production and egg quality, including the fatty acid profile in the eggs. Turmeric and probiotics supplementations positively impact egg production, egg quality, or unsaturated fatty acid profile in the egg. However, curcuma supplementation decreased egg production and egg quality of local ducks. Furthermore, the fatty acid profile was not influenced by these supplements. It is concluded that supplementation of turmeric at the level of 4% and probiotics at the level of 2% in the diet can increase egg production and egg quality of local duck.
Tujuan penelitian ini adalah untuk mengetahui efek substitusi protein tepung ikan dengan tepung pupa ulat sutera (Bombyx mori) terhadap performa produksi dan kualitas telur pada puyuh. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan dan empat ulangan dengan sepuluh ternak tiap ulangan. Perlakuan yang diberikan adalah R0: pakan mengandung 8% tepung ikan, tanpa tepung pupa ulat sutera (kontrol), R1: pakan mengandung tepung pupa ulat sutera menggantikan 25% protein tepung ikan, R2: pakan mengandung tepung pupa ulat sutera menggantikan 50% protein tepung ikan, dan R3: pakan mengandung tepung pupa ulat sutera menggantikan 75% protein tepung ikan. Hasil penelitian menunjukkan bahwa substitusi tepung pupa ulat sutera 25-75% nyata menurunkan (P<0.05) nilai konversi ransum, nyata meningkatkan (P<0.05) produksi telur tanpa mempengaruhi kualitas fisik telur yang dihasilkan. Kesimpulan yang dapat diambil adalah tepung pupa ulat sutera dapat digunakan 25-75% menggantikan protein tepung ikan. Kata kunci: puyuh, telur, tepung ikan, tepung pupa ulat sutera
ABSTRAKTujuan penelitian ini adalah mempelajari pengaruh pemberian bungkil biji jarak pagar (BBJP) yang telah difermentasi menggunakan Rizhopus oligosporus serta suplementasi enzim selulase dan fitase terhadap performa ayam petelur strain ISA-Brown unur 25-30 minggu. Penelitian ini menggunakan 200 ekor ayam petelur umur 25 minggu yang dialokasikan kedalam 5 perlakuan, masing-masing perlakuan terdiri atas 4 ulangan. Perlakuan ransum yang diberikan adalah: R0 = Ransum kontrol (tanpa BBJP), R1 = Ransum mengandung BBJP fermentasi 7,5%, R2 = Ransum mengandung BBJP fermentasi 7,5% + selulase 200 g/ton, R3 = Ransum mengandung BBJP fermentasi 7,5% + fitase 200 g/ton, R4 = Ransum mengandung BBJP 7,5% + selulase 200 g/ton + fitase 200 g/ton. Peubah yang diukur adalah konsumsi ransum, produksi telur hen day, produksi telur massa, bobot telur dan konversi ransum. Data dianalisis menggunakan sidik ragam (ANOVA) dan jika berbeda nyata diuji lanjut menggunakan uji jarak Duncan. Hasil penelitian menunjukkan bahwa pemberian BBJP 7,5%, baik yang tidak disuplementasi maupun yang disuplementasi enzim nyata menurunkan (P<0,05) konsumsi ransum, produksi telur hen day dan produksi telur massa, tetapi tidak mempengaruhi bobot telur. Berdasarkan analisis statistik, suplementasi enzim selulase atau fitase mampu memperbaiki konversi ransum dengan nilai sama dengan konversi ransum perlakuan kontrol. Kata kunci: ayam petelur, fitase, Jatropha curcas, R.oligosporus, selulase ABSTRACTThe objective of the experiment was to study the effect of feeding fermented Jatropha curcas L. meal (JCM) supplemented with cellulase and phytase on the performances of ISA-Brown laying hen aged 25-30 weeks. The Jatropha curcas meal was fermented using Rizhopus oligosporus. In this study 200 laying hens were used and distributed to 5 treatments and 4 replications in Completely Randomized Design. The diet treatments were: R0 = control diet (without JCM), R1; diet contained fermented JCM 7.5%, R2; diet contained fermented JCM 7.5% + celullase 200 g/ton, R3; diet contained fermented JCM 7.5% + phytase 200 g/ton and R4; diet contained fermented JCM 7.5% + cellulase 200 g/ton + phytase 200 g/ton. The parameters observed were feed consumption, hen day egg production, egg mass production, egg weight and feed conversion ratio. The results showed that feeding fermented JCM 7.5%, both enzyme supplemented as well as unsupplemented significantly decreased (P<0.05) the feed consumption, hen day egg and egg mass production. However, the treatments did not influence the egg weight. Supplementation of cellulase (R2) or phytase (R3) improved the feed conversion ratio with the value as same as the R0 diet.
Hati unggas betina memiliki peran vital sebagai tempat biosintesis prekursor kuning telur, karena perannya ini hati mudah mengalami kerusakan seluler. Tujuan penelitian ini ialah mengkaji efikasi suplementasi kurkumin dan penggunaan cahaya monokromatik dalam menekan histopatologi hati pada biosintesis kuning telur itik lokal. Pada penelitian ini digunakan seratus sembilan puluh dua ekor itik magelang betina. Rancangan penelitian yang digunakan ialah rancangan acak lengkap dengan susunan faktorial 4x4. Faktor pertama berupa dosis kurkumin, yaitu 0, 9, 18, dan 36 mg/ekor/hari. Faktor kedua adalah warna cahaya yang terdiri atas putih, merah, hijau, dan biru. Hasil penelitian menunjukkan bahwa degenerasi hidropik dan perlemakan pada hepatosit masih dalam kategori normal. Terdapat interaksi antara dosis kurkumin dan warna cahaya monokromatik yang menyebabkan penurunan konsentrasi serum glutamic-piruvic transaminase/glutamic-oxaloacetic transaminase (SGPT/GOT) dan malondyaldehid (MDA) hati (P<0,05), secara berurutan menurun hingga 24,63%, 24,75% dan 22,5%. Peningkatan kadar trigliserida dan kolesterol berkorelasi positif dengan peningkatan SGPT/GOT serum dan MDA hati. Suplementasi kurkumin dan penambahan cahaya monokromatik dapat menghambat kerusakan oksidatif hati itik yang sedang mensintesis kuning telur sehingga kondisi patologis dapat ditekan.
