Abstract

This study aims to evaluate the impact of using Moringa leaf flour fermented with Aspergillus niger in rations on the organoleptic properties of broiler meat. The research was conducted in the period August - September 2021 in the Commercial Zone and Animal Laboratory (CZAL) cage of the Department of Animal Husbandry, Faculty of Agriculture, UNIB. The research method used was a completely randomized design (CRD) with 4 treatments and 5 replicates. Each replicate involved 8 broilers, so the total sample used was 160 for all treatments. The treatments given include P0: Control (without the use of fermented moringa flour), P1: Use of 5% fermented moringa flour, P2: Use of 10% fermented moringa flour, and P3: Use of 15% fermented moringa flour. Observations were made on the 35th and 36th days after treatment, with an interval scale used to assess categories of organoleptic properties such as color, odor, taste, and texture of broiler meat. The results showed that fermented Moringa leaf flour did not improve the color, taste and texture of broiler meat. Using 10-15% fermented Moringa leaves produces a less fishy odor. It can be concluded that the use of 10% and 15% fermented Moringa leaf flour reduces the fishy odor of broiler meat without improving the color, taste and texture of the meat.   Keywords: Organoleptic Properties, Fermentation, Moringa Leaves, Broiler Meat   ABSTRAK Penelitian ini bertujuan untuk mengevaluasi dampak penggunaan tepung daun kelor (Moringa oleifera) yang difermentasi dengan Aspergillus niger dalam ransum terhadap sifat organoleptik daging broiler.

Abstract

The chicken endemic in Rejang Lebong Regency, Bengkulu Province, called burgo chicken, is the result of a cross between red jungle fowl and native chickens. The research aims to evaluate the production potential, population and population development scenarios of burgo chickens. The research was conducted in Rejang Lebong Regency, Bengkulu Province for 3 months. Fifteen breeders obtained using the snowball sampling method were used in this research. Data was obtained through interviews, filling out questionnaires, and observation; namely egg production, chick production, and population. Data is tabulated, discussed descriptively, and population development scenarios are prepared. The results of the research showed that the burgo population was 92 hens, 55 roosters, 17 hens, and 20 chicks. The productive hen was 13, producing 43.76 eggs/hen/year, a total of 744 eggs/13 hen/year, 386 (51.88%) were incubated by the hen, and 340 eggs (88.08%) hatched. In conclusion, egg production per individual is quite high, chick production is low, and population development is slow due to the low number of eggs laid, high chick mortality, being eaten by predators, sold and consumed by breeders. The scenario for increasing population and production is to increase the number of hens, the number of eggs laid, reduces mortality, protects chickens from predators, and improves rearing management.   Key words: Burgo Chicken, Production and Population, Development Scenarios   ABSTRAK Ayam endemik di Kabupaten Rejang Lebong, Provinsi Bengkulu yang disebut ayam burgo  merupakan hasil persilangan antara ayam hutan merah dengan ayam kampung. Penelitian bertujuan untuk mengevaluasi  potensi produksi, populasi dan skenario pengembangan populasi ayam burgo. Penelitian dilakukan  di Kabupaten Rejang Lebong, Provinsi Bengkulu selama 3 bulan. Lima belas peternak yang diperoleh dengan metode snowball sampling digunakan dalam penelitian ini. Data diperoleh melalui wawancara, mengisi kuisioner, dan observasi; yaitu produksi telur,  produksi anak ayam, dan populasi. Data ditabulasi, dibahas secara deskriptif, dan disusun skenario pengembangan  populasi. Hasil penelitian,  populasi burgo adalah 92 ekor ayam terdiri dari ayam jantan 55 ekor,  induk ayam 17 ekor, dan anak ayam 20 ekor. Induk ayam produktif berjumlah 13 ekor, menghasilkan  telur 43,76 butir telur/induk ayam/tahun, total 744 butir telur/13 induk ayam/tahun. Jumlah telur dieram induk ayam adalah   386  (51,88%) dan  340 butir telur (88,08%) menetas.  Kesimpulan, produksi telur per individu cukup tinggi, produksi anak ayam rendah, dan  perkembangan populasi lambat yang disebabkan oleh rendahnya jumlah telur dieram, tingginya kematian anak ayam, dimakan predator, dijual dan dikonsumsi oleh peternak. Skenario peningkatan populasi dan produksi adalah meningkatkan jumlah induk ayam, jumlah telur dieram,  menurunkan angka kematian, melindungi ayam dari predator, dan memperbaiki manajemen pemeliharaan.   Kata kunci: Ayam Burgo, Produksi dan Populasi, Skenario Pengembangan

Abstract

This study aims to evaluate the effect of using fermented Moringa oleifera leaf flour in the diet on broiler fat deposition (percentage of neck fat, heart fat, proventriculus fat, gizzard fat, abdominal fat, and sartorial fat). The research was conducted from 20 August to 25 September 2021 at the Commercial Zone and Animal Laboratory (CZAL) of the Animal Husbandry Department and the Animal Husbandry Laboratory, Faculty of Agriculture, Bengkulu University. The design used was a Completely Randomized Design (CRD) with four treatments, five replications, and each replication consisting of 8 chickens. The variables observed were the percentage of abdominal fat, sartorial fat, gizzard fat, heart fat, proventriculus fat, and neck fat. The results showed that the treatment had no significant effect (P>0.05) on gizzard fat, heart fat, and neck fat but had a significant effect (P<0.05) on abdominal fat, sartorial fat, and proventriculus fat. The percentage of gizzard fat ranges from 0.263% - 0.320%, heart fat ranges from 0.026% - 0.036%, neck fat ranges from 0.020% - 0.031%, abdominal fat ranges from 0.334% - 0.441%, sartorial fat ranges from 0.163% - 0.217%, and proventriculus fat ranges from 0.024%. % - 0.038%. It was concluded that using fermented Moringa oleifera leaf flour up to a level of 15% could not reduce gizzard fat, heart fat, and neck fat in broilers. Still, it improved abdominal fat, sartorial fat, and proventriculus fat.

Abstract

This study investigates the effect of adding different concentrations of senduduk (Melastoma malabathricum L.) leaf powder (SLP) on the microbiological and physicochemical properties of beef patties. Senduduk leaf is known for its antimicrobial and antioxidant activities, which may help improve the shelf life and quality of meat products. Beef patties were prepared with varying levels of SLP (0%, 0.5%, 0.75%, and 1%) and evaluated at 0 and 5 hours of storage for total plate count (TPC), moisture content, water holding capacity (WHC), and pH. The results showed that the addition of SLP did not significantly affect the TPC or WHC at both time points. However, the moisture content of the patties with 0.75% SLP was significantly higher at 0 hours, while no significant differences were observed after 5 hours of storage. Similarly, the pH values remained stable across all treatments. These findings suggest that while SLP can initially influence moisture retention, its antimicrobial and physicochemical effects are limited, particularly after cooking, which likely degrades the bioactive compounds. Future research should explore the use of SLP in low-temperature cooking or cold storage to maximize its potential as a natural preservative.

Abstract

This study aimed to analyze the physicochemical and organoleptic characteristics of rejected laying duck meat pepes after being coated with jackfruit leaf powder (JLP). The research design employed was a completely randomized design consisting of 4 treatments (P0: without any coating with JLP; P1: 5%; P2: 10%; and P3: 15% smearing of JLP) with 3 replications. The variables measured were cooking loss, water holding capacity (WHC), pH, and water content which were analyzed by Anova and multiple comparisons DMRT by significance level 0.05, and organoleptic which were analyzed by description. The results of the study showed that rejected laying duck meat smeared with JLP had no significant effect (P>0.05) on cooking loss, WHC pH, and moisture content of the pepes. However, the 15% JLP was able to enhance the aroma of the pepes. The average range value of the cooking loss was 14.00 to 15.33%, the WHC was 53.76-55.47%, the pH value was 6.22-6.29%, and the moisture content was 67.83-71,28%. The results of the hedonic quality test showed that the average value of the meat aroma ranged from 4.03-4.20 in the slightly fishy to a very non-fishy category, the interval scale test results showed P0, P1, and P2 in an interval scale of 3.40-4.19 (slightly fishy aroma), different from P3 which is included in the interval scale from 4.20 to 5.00 (very not fishy). The tenderness of the meat was 3.52-3.92 as the tender category, the taste of the meat was 3.88-4.10 as the delicious category. The results of the hedonic test showed that the average value of the aroma of meat ranged from 4.02-4.12, the tenderness from 3.39-3.64, and the taste from 3.88-3.97. All scores were in the liking category. It was concluded that 5% to 15% smearing of JLP did not change the physicochemical properties of rejected layer duck meat paste, but 15% application of it could increase the aroma.
