Abstract

Mangosteen peel extract contains good antibacterial compounds and is thought to be better when microencapsulated is formed. This study aimed to determine the effects of formulation of mangosteen peel ethanol extract associated to maltodextrin on activities of Escherichia coli. It was conducted by disk diffusion method according to Kirby-Bauer test in Mueller Hinton Agar (MHA) using three different concentrations namely: 100, 75, and 50 (%). Each formulation was tested as many as 10 µL disk -1 consisted of each treatment. The employed maltodextrin was obtained by enzymatic processing of arenga starch. Nine formulations were tested by measuring their bacterial inhibition activity in a Mueller Hinton Agar (MHA) medium.  The results showed that the effects of formulation between mangosteen peel ethanol extract and maltodextrin had the significant effect (P<0.05) on the antibacterial activities of Escherichia coli. It had been shown the ability to actively inhibit the bacterial growth at medium levels.

Abstract

Although feed is a major factor determining the productivity of ruminant livestock, feed, especially green feed, typically has a high fibre content that is difficult to digest effectively, leading to less efficient utilization of nutrients. As a result, efforts are needed to improve feed quality through microorganism-based fermentation, especially fermentative bacteria. The role of fermentative bacteria in improving the nutritional quality of ruminant feed is the subject of this study. The method used is to conduct literature research on relevant national and international journals. The results of the study showed that fermentative bacteria improve feed digestibility, convert lignocellulose into a simpler material, and produce volatile fatty acids (VFA), which are the main source of energy for livestock. Bacterial activity also helps in microbial protein synthesis and nutrient utilization. The type of bacteria, substrate composition, pH, and environmental conditions are some of the factors that affect the fermentation results. As a result, a good idea is to maximize the use of fermentative bacteria to improve the quality and productivity of ruminant animal feed.

Abstract

Drying is a crucial heat processing technique in animal feed production, used to reduce moisture content, extend shelf life, and maintain nutritional stability. Various methods have been applied, ranging from conventional convective drying (using ovens and solar energy) to advanced technologies such as microwave, infrared, freeze drying, vacuum, and hybrid drying. Each method has specific advantages and limitations in terms of energy efficiency, preservation of bioactive compounds, and effects on digestibility and feed palatability. This review examines the working principles of each method and their impact on nutrient quality, with a focus on process efficiency and the final feed value. Based on current literature, freeze and vacuum drying are superior in preserving heat-sensitive vitamins and compounds, while spray and fluidized bed drying enhance uniformity and feed intake. On the other hand, conventional techniques remain relevant due to their cost-effectiveness and simplicity. Therefore, when selecting a drying method, it is essential to consider the characteristics of the feed material and the formulation objective to ensure high-quality and sustainable feed production.

Abstract

Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh lama maserasi pollard (Triticum aestivum L.) dengan pelarut etanol 96% terhadap rendemen, profil fitokimia, dan nilai pH sebagai sumber betaine alami. Proses maserasi dibedakan menjadi empat perlakuan, yaitu maserasi dengan lama waktu 24, 36, 48 dan 72 jam. Parameter yang diamati meliputi nilai rendemen, profil fitokimia (fenolik, flavonoid, alkaloid, saponin, tanin, triterpenoid, dan steroid), serta kadar pH maserasi dan ekstrak kental. Hasil penelitian menunjukkan bahwa lama maserasi berpengaruh nyata (p kecil dari 0,05) terhadap nilai rendemen, dengan hasil tertinggi pada lama waktu maserasi 72 jam sebesar 6,58%. Profil fitokimia menunjukkan bahwa semakin lama maserasi, semakin kuat dan banyak jenis senyawa yang terdeteksi. Sementara kadar pH tidak berpengaruh secara signifikan terhadap lama maserasi, dengan hasil kadar pH pada larutan maserasi berkisar antara 6,47–6,60 dan kadar pH ekstrak kental stabil di angka 6,00. Sehingga dapat disimpulkan bahwa lama maserasi pollard dengan pelarut etanol 96% efektif dilakukan pada perlakuan 72 jam ditinjau dari nilai rendemen, profil fitokimia dan kadar pH. Pollard berpotensi sebagai sumber betaine alami yang dapat dikembangkan sebagai bahan baku feed additive untuk ternak.
