Abstract

Hormonal contraception is the most widely used contraceptive method in Indonesia, this is one of the risk factors for meningioma. Meningioma is the most common intracranial tumor. Risk factors for meningioma include a history of trauma, genetic history, hormonal exposure, history of menarche. in this study, the focus is on discussing literature on hormonal contraceptive exposure. This paper is a literature review. The method used in this literature review is to search and review various literature sourced from online databases such as PubMed, Google Scholar, and Proquest.  The keywords used in the literature search process include “hormonal”, “contraception”, “progesterone” “meningioma”. The use of hormonal contraceptives has been shown to increase the risk of meningioma, which is attributed to the progesterone receptors present in the normal meningens and the presence of the same progesterone receptors in meningiomas. The results of older studies have different results from recent studies, these inconsistencies may be associated with other variables such as duration, dose, and consistency in use, differences in the type of contraceptive use, current or previous use and other risk factors, further research needs to examine these variables and the underlying hormonal mechanisms to obtain more accurate results.

Abstract

Chives are a type of vegetable that comes from the lily family (bulb plants). This plant contains vitamins B and C, carotene and sulfur components. As time goes by, planting media not only uses soil media, but also uses air media, known as hydroponics. Good nutrition for hydroponic growth is one that contains micro and macro nutrients such as eco enzyme nutrients and fish waste. This research aims to determine the growth of chive plants (Allium tuberosum) in hydroponic growing media and to find out the most effective nutrients in increasing the growth of chives (Allium tuberosum) using hydroponic growing media. Data were collected using a non-factorial randomized block design (RAK), namely with nutritional treatment P1: AB Mix (5 ml/liter of air), P2: Eco enzyme + fish waste (5 ml/liter of air), P3: Eco enzyme (5 ml/liter of air), P4: fish waste (5 ml/liter of air). Based on the research results, P3 had a real influence on plant height at 1 and 2 MST with results of 9 cm at 1 MST and 13.33 cm at 2 MST. P1 had a real influence on plant height at 3.4 and 5 MST. The leaf area index parameter P1 had a significant effect at 5 MST with a result of 9.67 cm but had no real effect at 6 MST. The values of net assimilation rate, relative growth rate, and chlorophyll content were not significantly impacted by P1. The parameters of leaf area index, chlorophyll content, relative growth rate, and net assimilation rate were not significantly affected by P2, P3, or P4.

Abstract

Anthocyanin is one of the many compounds in dragon fruit skin that can be used as an antioxidant. Dragon fruit skin can also lower blood glucose levels. The fact that cases of diabetes mellitus are increasing every year shows that this disease needs serious treatment. This study aims to make dragon fruit skin extract formulated in the form of granules and make dragon fruit skin extract granules that meet the requirements as natural food coloring and to determine the content and effectiveness of dragon fruit skin extract (Hylocereus polyrhizus) which can lower blood glucose levels. This research method is experimental. The One Way Anova test and the Tukey HSD post-hoc test were used to analyze the data. The outcomes showed that there were 9 granule recipes that met the assessment test necessities. After being induced by 20% fructose solution, the glucose level study revealed that the treatment of dragon fruit skin extract at 100, 200, and 400 mg / kgBW was able to lower blood glucose levels in test animals. Winged serpent natural product skin concentrate can be formed as granules. Equations 2 and 3 produce the best tone. The consequences of the review reasoned that winged serpent natural product skin remove (Hylocereus polyrhizus) at dosages of 100, 200 and 400 mg/kgBW was viable in decreasing blood glucose levels in guinea pigs prompted by 20% fructose arrangement and a portion of 200 mg/kgBW gave an impact of lessening blood glucose levels that was practically equivalent to the positive control.

Abstract

Acne vulgaris is a chronic inflammation of the skin’s pilosebaceous unit, caused by oxidative stress due to reactive oxygen species (ROS) release. Oxidative stress conditions can be treated using natural antioxidants, namely ashitaba (Angelica keiskei). In contrast to previous studies that tested column chromatography fraction of the macerated ethanol extract, this study examined the liquid-liquid partition fraction of 80% methanol sonicated extract of Ashitaba herb. This study aims to determine the antiradical activity of various fractions of Ashitaba herb extract against 1,1-diphenyl-2-picrylhidrazyl (DPPH) free radicals. 80% methanol extract of the Ashitaba herb was fractionated using chloroform, ethyl acetate, and water solvents. Each ashitaba herb fraction was identified for the content of flavonoids and phenolic compounds and the antiradical DPPH activity was tested with ascorbic acid standard using a UV-Vis spectrophotometer. The IC50 value of each fraction was statistically analyzed using One-Way ANOVA and Posthoc Tukey. The results of phytochemical identification showed that ashitaba herb fractions positively contain flavonoids and phenolics. Antiradical activity of the chloroform, ethyl acetate, and water fractions against DPPH was indicated by IC50 values of 164.22±5.68 ppm (moderate); 8.70±0.12 ppm (very strong); and 243.60±8.14 ppm (weak). Statistically, each ashitaba herb fraction differed significantly from ascorbic acid (IC50 2.37±0.05 ppm). The ethyl acetate fraction has the strongest antioxidant activity and is in the same category of antioxidant strength as the ascorbic acid standard.

Abstract

Browning is a major constraint in in vitro propagation of Kepel (S. burahol). Therefore, the selection of an effective anti-browning compound can be useful to prevent browning in Kepel in vitro culture and produce explants that are able to regenerate. This study was aimed to investigate the effect of the addition of citric acid and PVP at different concentrations and incubation conditions on the prevention of browning in in vitro cultures of S. burahol. This research is an experimental study using S.burahol node explants. The research design used a Completely Randomized Design (CRD) with citric acid and PVP treatments of 300 and 400 ppm respectively and control incubated in dark and light conditions. Each treatment was repeated twice. The culture was incubated for 28 days. Observations were conducted on browning initiation time, browning intensity and callus initiation time. Data were analyzed descriptively. The results showed that citric acid treatment of 300 and 400 ppm and incubation of cultures in dark conditions effectively reduced the intensity of browning (0.2) and browning initiation time (6 DAI). In addition, the suplementation of 400 ppm citric acid and incubation in light conditions was also effective in initiating the fastest callus at 2 DAI. The results suggest that the addition of citric acid at concentrations of 300 and 400 ppm is more effective at slowing browning and reducing browning intensity for S. burahol node explants than PVP. The results of this study play an important role in supporting efforts to increase the productivity of S. burahol nodes growth through in vitro culture.

Abstract

Plantago major L. are known as weeds on plantations. Plantago major L. is effective to overcome pain because they contain secondary flavonoid metabolites that have the potential as pain relievers. The purpose of the experiment was to determine the analgesic effect of ethanol extract on Plantago major L. plant on male white mice. The experiment, phytochemical screening of ethanol and powder extracts from Plantago major L. plant, powder of simplicia characterization examination and analgesic effect using writhing test were carried out. As a pain inducer, 0.5% acetic acid is used intraperitoneally injected the lower abdomen of the mice and the amount of stretching is calculated with an interval of 5 minutes for 1 hour. The suspension of ethanol extract of Plantago major L. was given at a dose of 500, 1000 and 2000 mg / kg BW, 2% methampyron suspension as a positive control and 0.5% CMC suspension as a negative control. Pharmacological test results based on ANOVA test found that the amount of stretching between treatment groups was significantly different (p <0.05). The results of the analgesic effectiveness percentage obtained that the EEPM (Ethanol Extract of Plantago Major L.) suspension dose 500, 1000 and 2000 mg / kg BW had the highest analgesic power at a dose of 2000 mg / kg BW of 85.84%, EEPM suspension group 1000 mg / kg BW of 74.96 % and in the EETDS suspension group 500 mg / kg BW 62.37%.

Abstract

Mangrove diversity in Indonesia, including in Sonde Village, Rangsang Pesisir District, and Meranti Islands Regency, is one of the country's assets that is very important both ecologically, socially, and economically. This study aims to determine the diversity of mangrove species in the Tuah Sonde Forest Farmer Group Community Forest area. The method used was transect with random start with vegetation data collection conducted from June to July 2022. Data analysis includes quantitative descriptive analysis by calculating the Important Value Index (IVI) and the Shannon-Wiener Diversity Index (H'). The results showed that there were six mangrove species found in Sonde Village, namely Rhizophora apiculata, Ceriops tangal, Bruguiera cylindrica, Xylocarpus granatum, Sonneratia alba, and Avicennia marina. Sonneratia alba species dominated at the tree level with the highest INP of 167.66%, while Rhizophora apiculata dominated at the seedling and sapling levels with INPs of 111.52% and 76.74% respectively. The species diversity index (H') at the seedling and sapling level shows a medium category, while at the tree level is in the low category. Mangrove species diversity in Sonde Village is influenced by environmental factors such as tides and human activities, especially illegal logging which has the potential to reduce the sustainability of mangrove ecosystems in the region.

Abstract

The main objective of this research is: To obtain levels of the metal Cadmium (Cd) in the tissues of Tilapia Fish (Oreochromis mossambicus) caught from Lake Rawa Taliwang. The special benefit is to prevent humans from eating fish contaminated with Cd heavy metal. Research has been carried out on water bodies in Rawa Taliwang Lake. There are 2 research stations, namely in the eastern and western parts of the lake. Traps (Bubu) are used to catch fish as research samples. There were samples of 6 Mujair fish taken at each station. Next, the tilapia fish sample is placed in a plastic sample and then placed in the sample box. The tilapia fish samples were then destroyed in the UNRAM analytical laboratory, then analyzed for Cd content at the DLHK NTB Environmental Laboratory. Mujair fish muscle tissue was taken and then analyzed for Cadmium (Cd) metal content using an AAS (Atomic Absorption Spectrophotometer) tool. Concentrated HNO3 and HClO4 solutions are added to measure this heavy metal, then heated so that the solution becomes clear at a temperature range of 60-70ºC for 2-3 hours.  Next, the sample solution can be measured using AAS which utilizes an air-acetylene flame. The conclusion of this research was to find that the heavy metal content Cadmium (Cd) in the tissues of Tilapia Fish (Oreochromis mossambicus) taken from the waters of Lake Rawa Taliwang was 0.13 mg/kg (ppm).
