Abstract

Kombucha is a fermented beverage made from a mixture of sweet tea using kombucha microbes known as SCOBY (Symbiotic Colony Of Bacteria and Yeast). One of the flowers that has the potential developed as kombucha ingredient is yellow marigold flower (Tagetes erecta L.). The purpose of this study was to determine the antioxidant activity and organoleptic quality of yellow marigold flower kombucha on variations of sugar types and fermentation duration. This study used an experimental method with a Completely Randomized Design (CRD) with 2 factors. Factor I: variation of sugar types (G): palm sugar and Javanese sugar. Factor II: fermentation duration (F): 5 days and 7 days. The results of the study showed that the highest antioxidant activity of yellow marigold flower kombucha was 71.44% in G1F2 treatment (200 g palm sugar and 7 days fermentation duration) and the highest organoleptic quality of yellow marigold flower kombucha was brown color, quite sour taste, quite aromatic type of kombucha and quite liked. in the G2F2 treatment (200 g palm sugar and 7 days fermentation duration).

Abstract

Orangutans are arboreal primates and the only great apes native to Asia. Reproduction is crucial for the survival and long-term viability of orangutan populations. This review explores orangutan reproductive biology, focusing on its key features and the potential influences of environmental change. Orangutan (Pongo spp.) reproduction is marked by delayed sexual maturation, long interbirth intervals, and intensive maternal care, reflecting a slow life history strategy. Male bimaturism produces flanged and unflanged forms, each with different mating strategies shaped by social context. Female strategies, such as mate selection and resistance to coercive mating, play a critical role in reproductive outcomes. Climate change, through shifts in rainfall and temperature, is expected to affect food availability, potentially disrupting reproductive timing and offspring survival. The increasing presence of nanoparticles is also considered an emerging threat, though data specific to primates remains limited. Conservation efforts have focused on habitat protection, conflict mitigation, and ex-situ management, including rehabilitation and management of captive individuals in zoos; however, cryopreservation remains largely unexplored.

Abstract

Livestock health is a crucial factor that influences the success of animal farming. One of the determinants of livestock health is the presence of parasites. This study aims to identify the types of gastrointestinal parasites and determine their prevalence in Sapera goats at Jawara Farm. The research was conducted using three examination methods: native, sedimentation, and flotation. A total of 23 goat fecal samples were examined in the laboratory. The identification results revealed five types of gastrointestinal parasites: Haemonchus contortus, Trichuris spp., Eimeria hirci, Eimeria christenseni, and Eimeria aspheronica. The parasite with the highest prevalence was Haemonchus contortus (69%), followed by Trichuris spp. (39%), Eimeria aspheronica (26%), Eimeria hirci (17%), and Eimeria christenseni (13%). The highest average Egg Per Gram (EPG) was found in Trichuris spp. (379.17), categorized as a moderate infection. Environmental factors such as temperature, humidity, and pen hygiene are strongly suspected to influence the prevalence rate and severity of parasitic infections. This study is expected to serve as a foundation for efforts in controlling and preventing parasitic infections on farms.
