Ayam broiler merupakan salah satu sumber protein hewani yang digemari masyarakat Indonesia. Upaya peternak untuk meningkatkan produktivitas ayam broiler salah satunya dilakukan dengan cara pemberian imbuhan pakan antibiotic growth promotor (AGP). AGP digunakan sebagai pemacu pertumbuhan ternak, meningkatkan ketersediaan lemak dan protein ayam, serta meningkatkan efisiensi pakan. Namun AGP dalam pakan sudah dilarang penggunaannya, sehingga perlu adanya alternatif imbuhan pakan seperti acidifier. Acidifier yang umum digunakan yaitu asam sitrat. Hidroksisitrat (HCA) merupakan turunan dari asam sitrat dan telah ditemukan sebagai asam utama dalam asam kandis (Garcinia xanthochymus). Penelitian yang dilakukan pada bulan Agustus-Oktober 2020 ini dilakukan dengan metode pustaka. Hasil studi literatur ini menunjukkan pemberian ekstrak asam kandis pada pakan broiler sangat efektif sebagai pakan aditif pengganti antibiotik growth promotor (AGP). Asam organik berupa asam hidroksisitrat (HCA) yang terdapat didalamnya mampun menekan pertumbuhan bakteri di usus halus.

Diseases that often attack rice plants are bacterial leaf blight, this disease can reduce rice production by up to 60%. Control of bacterial leaf blight in addition to using chemicals can also use biological agents, one of which is Paenibacillus polymyxa. Testing of biological control applications begins with inoculation of Xanthomonas oryzae bacteria on ciherang rice seeds 9 days after planting (DAP). Planting rice using Randomized Block Design using biological control Paenibacillus polymyxa consists of four treatments, Control (P0), 2,5 ml l-1 (P1), 5 ml l-1 (P2), and 7,5 ml l-1 (P3). The biological control application is carried out on seeds, 10 DAP, 2 week after planting (WAP), and 4 WAP. Observations were made once a week to observe the rice growth and intensity of the disease. Observations were made in the vegetative phase. The results of the Paenibacillus polymyxa biological control test can reduce the level of bacterial leaf blight attack even though the difference in each treatment is not significantly different. The recommended concentration of Paenibacillus polymyxa biological control is 7,5 ml l-1. This concentration can reduce the level of bacterial leaf blight attack in the vegetative phase.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
