One of the advantages of broiler chickens is their short harvest period. Factors that influence their growth include the nutrient content of the feed. However, it will be difficult to get optimal growth only with conventional feed. Therefore, growth supplements are needed. Red dragon fruit water-extract contains flavonoids and vitamins that act as antioxidants. This research aimed to study the effect of red dragon fruit water-extract treatment in drinking water on the growth of broiler chickens. This research used 300 DOC male broiler chickens which were reared until they were 21 days old. This research was conducted using a completely randomized design, with 5 groups and 5 replications, each replication group consisting of 12 DOC. The five groups consisted of the control group (P0), P1 0.25%, P2 0.50%, P3 1%, and P5 2%. Parameters observed included the histological structure of the small intestine, pectoralis muscle, and spleen, as well as growth performance. The results showed that red dragon fruit water extract could increase villi length and area, ratio of villi length to crypt depth, number and area of goblet cells, fasciculus area, muscle fiber area and white pulp area, splenic organ index, as well as improving growth performance including chicken body weight and feed efficiency. Therefore, it can be concluded that red dragon fruit water extract can improve the histological structure of the small intestine, pectoralis muscle, and spleen, as well as increase the growth performance of broiler chickens, especially in red dragon fruit extract with a concentration of 2%

AbstrakPeningkatan permintaan daging ayam Broiler di pasaran menurunkan minat peternak terhadap ayam lokal. Oleh karena itu, diperlukan upaya peningkatan populasi ayam lokal yang berpotensi sebagai ayam pedaging. Salah satu cara yang dapat dilakukan adalah menyilangkan ayam betina Jawa super dengan ayam jantan Pelung yang diketahui memiliki pertumbuhan lebih cepat dibandingkan ayam lokal. Hasil persilangan tersebut diharapkan memiliki pertumbuhan cepat dan berpotensi sebagai ayam pedaging dengan karakter lokal. Tujuan penelitian ini adalah mempelajari pertumbuhan, morfometri tubuh, dan fenotipe ayam Super pelung (SUPEL) hasil persilangan ayam betina Jawa super dengan ayam jantan Pelung. Parameter yang diukur adalah berat badan, morfometri tubuh, dan fenotipe ayam Supel. Selain itu dilakukan pengukuran berat, warna, morfometri, dan analisis proksimat telur ayam Jawa super. Hasil menunjukkan rerata berat badan ayam Supel saat Day Old Chicken (DOC) sebesar 33,57 ± 2,44 g dan mencapai 1.164,00 ± 98,20 g pada umur 3 bulan. Fenotipe anak ayam Supel menunjukkan ciri-ciri kombinasi dari kedua indukan. Sementara itu hasil pengukuran berat telur ayam Jawa super diperoleh rerata sebesar 43,15 ± 3,57 g. Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa ayam Supel hasil persilangan memiliki pertumbuhan yang cepat dan memiliki karakter fenotipe seperti ayam lokal.AbstractThe increasing demands of Broiler chicken meat in the market lower farmers' interest in the local chicken breed. Therefore, effort is needed to improve the local chicken population for its potential as Broilers. One of the solutions is to crossbreed between Jawa super hens and Pelung roosters with faster growth than other local chickens. The crossbreed chicken (Supel chicken) is expected to have faster growth and the potential as Broilers with local characteristics. The purpose of this study is to evaluate growth, body morphometry, and the phenotype of Super pelung (SUPEL) chicken. Parameters measured were body weight, body morphometry, and phenotype of Supel chicken. The measurements of weight, color, morphometry, and proximate analysis were also conducted on Jawa super egg. The results showed that the weight of Supel chicken during Day Old Chicken (DOC) was 33.57 ± 2.44 g and reached 1,164.00 ± 98.20 g in 3 months. The phenotype of Supel chicken showed combination characteristics of the two broods. Meanwhile, the weight of the Jawa super chicken egg average of 43.15 ± 3.57 g. It can be concluded that Supel chicken has a faster growth rate and phenotypic characters resembling Indonesia's local chickens.

During the COVID-19 outbreak, economic sectors slowed down and caused a significant impact on almost any level of society, especially the middle to lower class income. Thus, a strategy needs to be developed to overcome this situation. The Ngoro-Oro Village has potency in the livestock sector, especially in the development of superior hybrid Jawa super chicken. Therefore, the purposes of our community service in the Ngoro-Oro Village were to develop superior hybrid Jawa super chicken and use black soldier fly larvae as an alternative feed for chicken. We distributed 105 Jawa super hens aged ± three months and 21 superior free-range roosters. Furthermore, the hens and rooster were mated at the age of ± six months with a ratio of 5:1. The hybrid chickens were evaluated for their body weight and morphometric measurements until the age of four months. We also monitored the farmer community’s use of black soldier fly larvae as an alternativ e feed for chickens. The hybrid chicken at the age of 4 months old has a body weight of about 971.64 ± 271.06 grams with a height of about 41.73 ± 5.87 cm, head’s length of 5.01 ± 0.44 cm, body length of 22.82 ± 3.14 cm, body width of 10.68 ± 1.49 cm, wing’s length 19.14 ± 2.67 cm, thigh’s length 11.95 ± 1.71 cm, and leg’s length is about 7.91 ± 1.41 cm. Moreover, Ngoro-Oro farmers can improve the community’s economy by selling superior hybrid Jawa super chicken at a price 75,000 – 85,000 rupiahs per head. Through all of this community service program, it could be concluded that superior hybrid Jawa super chicken is potential to be developed as broiler, and the farmer community could develop black soldier fly larvae as an alternative feed for chicken.

The Covid-19 pandemic severely affect the economic sector especially on food security and purchasing power. Based on the program in 2019 and 2020, it has been found that jawa super hen can lay up to 20- 25 eggs/hen/month with good maintenance and feeding. This study aimed to solved the food security problem in Ngoro-oro village by educating the villagers about how to market their jawa super chicken eggs as an effort to improve the economic standard of the community. The activity was carried out for 7 months included producing alternative chicken feed using black soldier fly larvae, post-harvesting management, and evaluating consumer egg preference survey using google form which spread randomly over some different communities to determine the best promotional strategy. The Ngoro-oro villagers eagerly attended both of the trainings. Some of them even succeeded in developing maggot from the black soldier fly which can be used to produce as an alternative feed for poultry. We got 126 respondents from the consumer egg preference survey. We found that around 60% respondents prefer to consume medium size egg, light to dark brown egg and around 80% respondents are interested to try consuming jawa super eggs. Most of the respondents prefer simple and easy to read label as well as carton-based packaging for the eggs. Collecting all the information together, we found that jawa super eggs may have potency to be sell in the market as medium size brown eggs supported by a good brand, packaging, and promotion strategy
