Abstract

This study aims to determine the effect of the level of C. odorata (CO) silage-based concentrate on the blood profiles of Bali cattle. Three male Bali cattle (initial 2 years old with CV = 19,28%) were randomly assigned to one of three meals: rice straw and concentrates containing C.odorata silage 30% (RCO30) or  C.odorata silage 40% (RCO40) or C.odorata silage 50% (RCO50), respectively, using a 3 x 3 Latin Square Design. The was no significant effect between treatments (P> 0.05) on blood cholesterol (195.74-220.49 mg/dL), blood urea (48.41-49.44 mg/dL), total blood plasma (6.08-6.93 g/dL), blood haemoglobin (Hb; 18.18-18.92 g/dL), hematocrit levels (45.56-53.03%), erythrocytes (7.06-8.24 106/l), and leucocytes (8.56-8.84/l). Blood glucose levels, however, differed significantly (P<0.05) between treatment. Feeding Bali cattle with different levels of C.odorata-based concentrate resulted in the same effect on all blood parameters except blood glucose. Therefore, it is recommended that the use of C.odorata in a ration of Bali cattle can be up to 50%.

Abstract

Dendrobium lasianthera (Orchidaceae) is one of the potential plants as ornamental plants because it has beautiful and long-lasting flowers. Propagation of orchid plants through in vitro culture technique has been widely done to meet market demand. One of the supporting factors in plant propagation through in vitro culture techniques is growth regulators. Cytokinin is one of the growth regulators commonly used in plant propagation, including orchids. The study aims to determine the effect of several cytokinins and find the best type for shoot induction of Dendrobium lasianthera. The method used a Completely Randomized Design (CRD) with 4 treatments and 6 replications with several types of cytokinis (control; BAP 1.2 mg/L, Kinetin 2 mg/L, and Thidiazuron 1 mg/L) in Murashige & Skoog (MS) media. The results showed that several cytokinins significantly affected the number of shoots, time of shoot appearance, and shoot length of D. lasianthera. Thidiazuron was the best cytokinin for in vitro shoot induction of D. lasianthera

Abstract

The Control of Culex sp. using synthetic larvicides is harmful to the environment and human health. Biolarvicide from red shoot leaves (Syzygium myrtifolium) is a safe alternative for the environment and human health. This study aims to determine the effect of Syzygium myrtifolium leaves extract with ethanol solvent and water solvent on larval mortality and the LC50 values of these extracts. ANOVA test results (α = 0.05) on the mortality of Culex sp. larvae exposed to the ethanol extract and aqueous extract of S. myrtifolium leaves consecutively showed F-calculated (287)>F-tabulated (3,11) and F-calculated (153)>F-tabulated (3, 11). The treatment of S. myrtifolium leaves extract with ethanol and water solvents had a significant effect on the mortality of Culex sp. larvae. The LC50 value of the ethanol extract and the aqueous extract of S. myrtifolium leaves are 1659 ppm and was 2053.7 ppm. It can be concluded that S. myrtifolium leaves extracts with ethanol solvent and water solvent have an effect on the mortality of Culex sp. larvae, but are not yet effective as biolarvicide

Abstract

A study comparing the effects of red betel leaf decoction, mangosteen peel juice, and conventional medication on blood glucose levels in individuals with type II diabetes mellitus was conducted in Indonesia. The research involved three groups of eight participants each, selected through purposive sampling. Following administration, the average blood glucose level was 190.75 mg/dL for red betel leaf decoction, 194.38 mg/dL for mangosteen peel juice, and 186.50 mg/dL for conventional medication. Surprisingly, there was no significant difference in the effectiveness of red betel leaf decoction and mangosteen peel juice in managing blood sugar levels, with a p-value of 0.582 (p<0.05). These findings suggest that both herbal interventions are comparable to conventional medication in regulating blood glucose levels among type II diabetes patients. In conclusion, the study highlights the potential of red betel leaf and mangosteen peel as alternative non-pharmacological interventions for managing diabetes. Further research is warranted to explore their mechanisms of action and long-term effects on diabetes management
