Abstract

Animal feed is one of the most important things for sheep and goat farming. Without a good balance of feed ingredients, sheep and goats will not grow optimally, because the feed given to livestock does not match their needs. Therefore, we need an appropriate way to regulate the nutritional needs of feed required by sheep and goats. This study aims to meet the nutritional needs of sheep and goats from a variety of concentrate and forage feed ingredients. To meet the nutritional needs of feed ingredients, it is necessary to do research on optimization in the manufacture of ration feed formulas. If the nutritional needs have been met, the next goal is to predict the price of the ration economically in order to provide a profit. To solve this problem, an approach is needed to model the relationship between concentrate feed ingredients and forage feedstuff variables. Multivariate linear regression is a regression analysis method that involves more than one response variable.

Abstract

Situ Patengan is standing water located at the foot of Mount Patuha, Patengan Village, Rancabali District, Bandung Regency, West Java. Situ Patengan is also used for various activities including as a tourist area, fishing, and tea plantations as well as plantation business rights. The number of activities around Situ Patengan can potentially affect the quality of the waters and the organisms in it, including macrozoobenthos organisms. The presence of macrozoobenthos can also be used as a bioindicator of water quality because it is very sensitive to environmental changes. This study aims to determine the diversity, abundance, and influence of environmental factors on macrozoobenthos and to determine the water quality of Situ Patengan. The research was conducted using the purposive sampling method. Three stations are determined based on environmental factors and land use in the inlet area, forest edge, and tourism area. Based on the results of the study found 3 macrozoobenthos phyla, namely Molluscs (Pomacea canaliculata, Filopaludina javanica), Annelida (Lumbriculus sp.), and Arthropoda (Macrobracium rosenbergii, Enallagma sp., Pelocoris femoratus). Macrozoobenthos diversity ranged from 0.13-1.12 with low to moderate categories while abundance ranged from 11-91 ind/m2 and the Dominance Index in Situ Patengan ranged from 0.003-0.453 with the dominant species being Pomacea canaliculata. The Family Biotic Index shows results from 5.94 to 6.50 with the criteria that the waters at each station are not in good condition. The water quality of Situ Patengan based on macrozoobenthos bioindicators is moderate to heavily polluted. Environmental factors in this study such as depth, brightness, temperature, pH, salinity, and DO have a very low correlation to the family biotic index.

Abstract

Hypertension is a chronic disease that is most often found in society. Hypertension is associated with increased production of superoxide radicals and endothelial dysfunction, which causes oxidative stress characterized by increased levels of MDA. Mango mistletoe contains secondary metabolic compounds such as flavonoids which act as natural antioxidants. The use of antioxidants from manga parasites is an alternative to neutralize the increase in MDA in the body and neutralize free radicals. This study aims to determine the levels of MDA in hypertensive rats (DOCA-Salt) exposed to Mango mistletoe Methanolic Extract (EMBM) for 14 days. This study used the true experimental design method with completely randomized design on 50 male Wistar rats, differentiated into 5 treatments, namely control (-), control (+), treatment 1 dose 50 mg / KgBB, treatment 2 doses of 100 mg / KgBB and treatment 3 doses 200 mg / KgBW. Each treatment had 5 replications. Data analysis used oneway ANOVA and post hoc tests, namely JAMOVI version 1.1.9.0 which was used to determine differences in pulmonary MDA levels between groups and pulmonarymalondialdehyde (MDA) were analyzed by spectrophotometry. The results of this study indicated that pulmonary MDA levels in hypertensive rats (Doca salt) exposed to EMBM showed very significant differences between all groups. This is evidenced by the p value analysis that is <0.05, namely <0.001 so that it can be concluded that EMBM can reduce MDA levels in rats Hypertension. This effect is controlled by EMBM at a dose of 50 mg / KgBB which is the optimum dose in reducing pulmonarymalondialdehyd.

Abstract

Javan langur population has decreased, because the natural habitat of Javan langurs is decreasing from year to year, in addition to the rampant fishing of langur for trading. In order to suppress and reduce the habitat destruction of these wild animals, an effective and sustainable land rehabilitation effort is needed by recording the types of forage plants that Javan langurs like and the behavior of Javan langurs in foraging for their food. One of the efforts made to create a natural breeding place. The purpose of this research is to determine whether there is a specific Javan langur eating behavior pattern, in addition to knowing whether there is a change in Javanese langur eating behavior towards the type of food given. This observation uses the Continuous Recording method of recording. The results obtained will be processed in a qualitative descriptive form (narrative). From the results of this study, it was found that there was a specific feeding behavior for each type of feed given based on the size of the leaves, when consuming calliandra with smaller leaves the langurs did not need to pick the leaves first, it was different when langurs ate mountain amethyst and telasih which were larger in size so they tended to picking and tearing it first to get smaller leaf size, and there is a change in the diet of the type of feed given, namely langurs tend to fight more for calliandra plants because calliandra has fruit as well as flowers and also smaller leaf size making it easier for langurs to eat it . This is also shown by the higher number of chews on calliandra, which is 25 chews for 10 seconds.

Abstract

Kirinyuh (Chromolaena odorata) is one of the wild plants found that is difficult to eradicate because it has a high defense, so this plants is considered a weed plant that is detrimental to farmers and planters. However, the kirinyuh plant has the potential to be developed as an antibacterial. One of the natural ingredients that show pharmacological effects is flavonoids. This study aims to determine the antibacterial activity, and the effective concentration of kirinyuh extract in inhibiting the growth of Enterobacter sakazakii, Salmonellla typi, and Listeria monocytogenes bacteria. To get the extract used extraction method by maceration of immersion using 96% ethanol as solvent. The concentration of kirinyuh extract used was 20%, 40%, 60%, 80%, and 100%. While the positive control was used Ampicillin and negative control was used ethanol 96%, and for testing the antibacterial activity was carried out using the well difsusion method. The results of the antibacterial activity test were analyzed using ANOVA with a 95% confidance level and continued with Duncan’s Multiple Range Test (DMRT). The results showed that the extract concentrations of 20%, 40%, 60%, 80%, and 100% had given inhibitory activity to the growth of the test bacteria. At a concentration of 100%, kirinyuh extract was more effective as an antibacterial against bacteria Enterobacter sakazakii, Salmonella typi, and Listeria monocytogenes bacteria compared to other concentrations. The increase in the concentration of kirinyuh extract showed the larger the diameter of the inhibition zone for bacterial growth. The results of the inhibitory power test of kirinyuh extract against bacteria Enterobacter sakazakii with an average value of the inhibition zone of 6,66 mm, and against Salmonella typi the average value of the inhibition xone was 4,83 mm, and Listeria moncytogenes with an average value of 5, 60 mm.
