Abstract

Diabetes mellitus (DM) is a chronic metabolic disorder caused by high blood sugar levels due to lack of insulin function. Insulin is a hormone that helps blood sugar enter. Insulin injections are the main therapy for treating diabetes mellitus, they are relatively expensive and long-term use can cause side effects such as hypoglycemia. Other alternatives need to be found for the treatment of Diabetes Mellitus (DM), one of which is green tea. The aim of this research was to determine the effect of steeping green tea on the blood glucose levels of mice (24 males) which were divided into 4 groups. Mice were selected using the Simple Random Sampling technique representing 4 dose groups, namely: control group, brewed green tea at a dose of 30mg/0.5cc/day, brewed green tea at a dose of 35mg/0.5cc/day and green tea. brew at a dose of 40mg/0.5cc/day. The treatment was given orally for 6 repetitions. For 15 consecutive days. Data analysis used the One ANOVA test with a significance level of 5% (p<0.05) followed by the LSD test with a confidence level of 95%. The results of the study showed that there was a significant effect on reducing glucose levels in mice. Mice given a dose of 30, 40 and 45% brewed green tea experienced a decrease in glucose levels of 43, 32 and 40.27% respectively compared to controls.

Abstract

Singgalang Cabbage is one of the local cabbage cultivated on the foothills of Mount Singgalang, West Sumatra. Recently, the existence of this cabbage has decreased, so conservation and preservation efforts need to be carried out. This research was conducted to develop method for in vitro propagation and preservation of singgalang cabbage. The Murashige and Skoog (MS) were used as basal media with two experimental stages, i.e., shoot initiation with 6-Benzylaminopurine (BAP), and root induction and plantlet preservation with modification of MS media. The nodal and shoots were used as explants. The results showed that increment of BAP concentrations gave a significant effect on shoot initiation after 60 days of treatment. MS media-enriched with BAP 2 mg/L gave significant increment of shoots (4 shoots/nodus) and leaves (11.67) numbers when compared to other treatments. For root induction and plantlet preservation, it was found that the earlier of root formation was observed in modification of MS media at ½ and ¼ strength. Meanwhile, MS media at ⅛ strength was observed to be better media for plant height increment (4.75 cm) when compared to other treatments. It was found that the plantlets survived and grew well after 120 days under in vitro condition.

Abstract

This study was intended to analyze the abundance of rebon shrimp in the Sangoro lagoons of Sumbawa Regency. This research was conducted in Labuan Sangoro, Sumbawa Regency, West Nusa Tenggara. There were three sampling sites we choosed in this research based on the habitat characteristics, namely seagras beds, coral rubble, and mangrove area. We implemented the swept area technique to collect samples using scoop net with 60 cm length, 20 cm width, and 0,5mm mesh size. Rapia ropes were pulled along 50 m for each transect line drawn perpendicular to the shoreline. next, four 10 m transect lines were drawn parallel to the shoreline. The sampling was done by pulling the scoop net along the line transect so that a volume of the scoop net was obtained. In addition, the number of individuals was counted in each 10 m transect line. This research showed that only one species of rebon shrimp found in reseach area, namely Acetes Intermedius. Among three sampling sites, the mangrove area has a highest abundance of shrimp (12506,7 ind/L), followed by seagrass beds area (12189,0 ind/L), and coral rubble area (5102,8 ind/L). It can be concluded that mangrove and seagrass beds are habitat mosly prefered by rebon shrimp.

Abstract

Aquatic insects are among the most successful groups of macroinvertebrates in freshwater habitats. This condition is indicated by the composition, presence and wide distribution as well as the ability of insects to adapt to various types of freshwater habitats which are components of bottom water communities. The aim of this research was to determine the diversity index, species richness index and dominance index of aquatic insects in Colo Dam, Nguter District, Sukoharjo Regency. This research method is quantitative descriptive. Quantitative analysis includes measuring the Diversity Index (H'), Species Richness Index (R1) and Dominance Index (D). The results of research on water insects at Colo Dam found 27 species. The highest number of individuals is the Water Strider with 75 species, while the fewest species are Rhinocypha perforata with 16 species. The conclusion of this research is that the Diversity Index of 3.23 is considered moderate. The type of Wealth Index obtained at 3.67 is considered medium and the Dominance Index at 0.0416 is considered low. Recommendations for further research include adding a Biotic Index to see the quality of the waters in the Colo Dam. It is hoped that the results of this research can become a reference or further research.

Abstract

Timbanuh Hiking Track is one of the hiking tracks in Gunung Rinjani National Park. This track has four types of potential habitats for birds. This research aims to map bird diversity and their distribution along the Timbanuh Hiking Track. Data collection uses the point count method. Observations were carried out eight times, with a repetition period of two weeks. Bird diversity was analyzed using the Shannon Wiener Diversity Index. Scatterplots are used to map the distribution of birds along hiking track. The results show that on the Timbanuh Hiking Track there are 46 species of birds belonging to 29 families, with a high species diversity index of 3.52. The distribution of bird species is closely related to the four types of habitats on the track. There are four species of birds that are protected based on Minister of Environment and Forestry Regulation Number P.106 of 2018, as well as two species with Near Threatened status according to IUCN. The high diversity of birds, the existence of protected bird species, and the threatened status of birds mean that conservation efforts need to be increased by developing bird habitats along hiking track.

Abstract

Mangosteen peel is a waste that can be used as a feed additive. The function of xanthones in mangosteen peel as anti-tumoural, antioxidant, anti-inflammatory, anti-allergic, anti-microbial, anti-fungal, and anti-virus. The research aims to determine the effect of administering mangosteen peel extract in drinking water on the performance of broiler chickens for 35 days which was carried out in Dajan Peken Village, Tabanan District, Tabanan Regency, Bali. The design used was a Completely Randomized Design (CRD) with 4 treatments and 4 cage units as replications. Each cage unit contains 4 broiler chickens so that the total research material is 64 broiler chickens aged 11 days. Drinking water treatment: drinking water without mangosteen peel extract as control (P0), drinking water containing 1% (P1), 2% (P2), and 3% (P3) mangosteen peel extract. The variables observed were initial body weight, final body weight, body weight gain, ration consumption, ration conversion, drinking water consumption. The results showed that the final body weight in treatment P1 (2.108.3 g/head) with an increase in body weight of 1.627.4 g/head was higher than in treatments P0, P2, and P3 but was not significantly different (P>0.05) with the lowest ration conversion value (1.54). Drinking water consumption in treatment P1 (5.556.2 ml/head) was higher than in treatments P0, P2, and P3) and significantly different (P<0.05) from treatment P0 (4.628ml/head). Conclusion: Providing mangosteen peel extract (Garcinia mangostana L.) in drinking water at a level of 1% can provide optimal results to improve broiler performance and reduce feed conversion.
