Abstract

Dendrobium jacobsonii orchid is a flora whose distribution is limited to the eastern part of the island of Java, with Mount Lawu as the western limit of its distribution. This endemic epiphytic orchid of Java is currently threatened due to habitat destruction and illegal hunting. One of the initial efforts to conserve the Dendrobium jacobsonii is to know its population in nature and identify the characteristic of its habitat. The aim of this study was to determine the population size and habitat character preferences of Dendrobium jacobsonii. This research was using the purposive transect method and was carried out in March 2019. 189 clumps of Dendrobium jacobsonii orchid were found in the exploration. The distribution pattern was found to be clustered at an altitude of 2200-2400 masl and 2700-3000 masl. Most of Dendrobium jacobsonii were found in the temperature range of 22-27 °C. The air humidity preference of Dendrobium jacobsonii can be found in the range of 63.1-68%. While the light intensity was in the range of 2000 – 10.000 lux.

Abstract

Shigellosis is an infectious disease that is mainly caused by Shigella flexneri. Antibiotics resistance became the reason to develop an alternative of plant-based antibacterial, one of them is made from pisang awak. The utilization of pisang awak is still rare, it makes the economical value of Pisang awak is low. Several studies have revealed that several varieties of bananas contain antibacterial bioactive compounds in form of saponins, tannins, and alkaloids. This research aimed to determine the antibacterial potential of ethanol extract of various parts of pisang awak organs against the growth of S. flexeneri, as well as knowing the value of Minimum Inhibitory Concentration (MIC) and Minimum Killing Concentration (MKC). Antibacterial activity test were performed using disc diffusion (Kirby Bauer) and dilution method with various concentrations at 2.5%, 5%, 7.5%, 10%, 12.5%, 15%, and 17.5% (b/v). the result showed that the stem and leaves extract of Pisang Awak had an antibacterial activity which was indicated by the diameter of the inhibitory level of 20.98 mm dan 20.91 mm respectively. The MIC value of the stem and leaves was 2.5% (b/v), while the MIC value of the two extracts was not obtained.

Abstract

Diabetes mellitus is a disease characterized by hyperglycemia due to the destruction of pancreatic cells as insulin-producing cells. Natural ingredients from plants are an alternative for diabetes treatment, one of which is beard musa (Tillandsia usneoides L.). Beard musa is a plant that has bioactive compounds in the form of flavonoids that have the potential to help control blood sugar levels. This study aims to determine the effect of beard musa ethanol extract on reducing blood sugar levels and histopathological description of the pancreas of white rats (Rattus norvegicus) induced by alloxan. The study was divided into five treatment groups, namely positive control, negative control, dose I (dose of 125 mg/kg BW), dose II (dose of 250 mg/kg BW), and dose III (dose of 500 mg/kg BW). The test animals used were white rats weighing 150-300 grams which were acclimatized for 7 days. After that, the test animals were induced with alloxan for 7 days before treatment to determine the hyperglycemic effect. The treatment in each group was carried out for 14 days in which negative control was given aquadest, positive control was given glibenclamide, and doses I, II and III were given beard musa extract with 4 times of blood collection, namely days 0, 7, 14, and 21. Then the phytochemical screening was carried out with the flavonoid test and the alkaloid test. On day 21, mice were sacrificed to make histological preparations. The results showed that the three doses of beard musa ethanol extract were able to reduce blood glucose levels in hyperglycemic rats, where a dose of 250 mg/kg BW was more capable of providing a hypoglycemic (antidiabetic) effect to normal blood sugar levels in hyperglycemic white rats with successive decreases during 14 days compared to other doses. While the ethanol extract of beard musa at all doses did not affect the structure of the pancreatic cells of hyperglycemic white rats.

Abstract

The South Coast of Gunungkidul has beaches that have a diversity of marine life, especially gastropods. The high number of tourists and the existence of community activities that utilize marine life may disrupt the sustainability of the ecosystem on the coast. The aims of this study are the diversity, abundance, level of diversity, evenness, and environmental factors that influence them. The research was conducted at Ngobaran Beach, Nguyahan Beach, and Watu Kodok Beach in May-August 2016. Data were collected using the quadratic method with a total of 75 plots (3 times). Based on the research found 13 families of 36 species. 5 species were frequently appeared in three locations, namely M. granulata, M. literate, M. paupercula, C. coronatus, and C. matriculates, the most abundant of which was M. granulata (Ngobaran Beach: 160 ind/75 m2; P. Nguyahan: 82 ins/75 m2; Watu Kodok Island: 36 in/75 m2). The level of diversity was moderate (Ngobaran Island: 1.73; Nguyahan Island: 2.35; Watu Kodok Island 2.65) and the evenness level was fairly even-almost evenly (Ngobaran Island: 0.60; Nguyahan Island: 0.60). 0.76, P. Watu Kodok: 0.86). Based on the results of the analysis of the relationship between environmental factors and gastropods using CCA, 4 groups were found. Group 1 consisted of 10 species affected by salinity. Group 2 consists of 5 which are affected by water temperature. Group 3 consisted of 11 species affected by COD, BOD, and DO. Group 4 consisted of 10 species that were not affected by the measured parameters. Based on the results, it can be concluded that the diversity of gastropods on the three beaches is moderate.

Abstract

Dragonflies play an important role in controlling other insect populations in nature, and are also natural indicators of environmental cleanliness. This study aims to reveal the population of dragonflies in the Gajah Wong river in urban areas in Yogyakarta. The method of determining the research area is to use transects following the river flow, and dividing the research area into 8 locations. The length of each observation site is adjusted to the distance between the large bridges that cross the top of the river. The results showed that there were 16 types of ordinary dragonflies and 9 types of dragonflies found there. The species with the highest number was Pseudagrion rubriceps as many as 255. and the least species was Gynacantha subinterrupta, Onycothemis culminicola, Ischnura senegalensis, Pseudagrion microcephalum, each found only 1 individual. An interesting finding was the presence of 2 types of Javan endemic dragonflies that were recorded along the research site.

Abstract

Malaria is an infectious disease that occurs throughout the world, especially in the tropics. One of the factors that cause the high incidence of malaria is the behavior of the community towards malaria. People's lives during the Covid-19 pandemic have changed a lot, especially in the field of individual hygiene and the environment. Data from the Talawaan Health Center in 2020 found 4 cases of people suffering from malaria in Talawaan District, North Minahasa Regency, which increased from 2019 with a total of only 2 cases of malaria infection. This study aims to determine the behavior of the people of Kolongan Village, Talawaan District, North Minahasa Regency, towards malaria during the Covid-19 pandemic. This study is a descriptive study that is observational in nature. The people of Kolongan Village, Talawaan District, North Minahasa Regency, have good knowledge about malaria and the signs and symptoms of malaria during the Covid-19 pandemic, but knowledge related to the malaria incubation period is still limited. Respondents' attitudes regarding malaria during the Covid-19 pandemic have been relatively good, which is shown by closing doors and windows to avoid mosquitoes from entering, maintaining environmental cleanliness for malaria prevention, and draining puddles to avoid mosquito shelters.
