Abstract

Anemia is a condition when the body's hemoglobin levels decrease. Hemoglobin serves as a carrier of oxygen throughout the body. Pregnant women are one of the populations most susceptible to anemia because their bodies' nutritional and physiological needs change throughout pregnancy. One factor influencing the occurrence of anemia in pregnant women is a lack of knowledge about nutrition during pregnancy. This study aims to determine the anemia case, the level of knowledge, and the relationship between the level of knowledge about nutrition and the anemia case in pregnant women. The type of research conducted is an observational analytical research with a cross sectional approach and uses Spearman rank data analysis with a sample size of 33 respondents. The results of the study showed that the anemia case was 63.6%, the level of knowledge of respondents was dominated by a low level of knowledge, and there was no relationship between the level of knowledge about nutrition and the anemia case in pregnant women with a significance value of 0.578% and had a weak relationship with a correlation value of 0.101%.

Abstract

Tuna botok is a popular traditional food from Pontianak with high nutritional value, but its shelf life is short due to its susceptibility to spoilage. Proper packaging is essential to extend its shelf life and enhance the value of Pontianak's traditional foods. This study aims to evaluate the quality of tuna botok packaged in glass jars during storage. Measurements of moisture content, ash content, protein content, fat content, and total plate count were conducted on days 5, 10, 15, and 20 of storage. The results indicated that storage for up to 20 days had no effect on ash and fat content, but significantly impacted moisture and protein content. After 20 days, the total plate count remained within acceptable limits, with the product containing 66.56% moisture, 2.27% ash, 14.76% protein, and 11.78% fat.

Abstract

Stevia (Stevia rebaudiana) is a perennial semi-herbaceous plant whose leaves can be used as a sweetener for food and beverages. Stevia sweetener has low calories so its use is not bad for health. Propagation of Stevia by stem cutting using the top is a simple, fast, and easy propagation technique. This study aimed to obtain the optimum concentration of GA3 and the correct propagation method for Stevia cuttings for lowland areas. The research was conducted at the Green House, Biology Study Program FMIPA UNJ. The method used was an experimental method with a completely randomized design, consisting of 3 experiments, namely the provision of GA3 with a dose of 10 ppm, 30 ppm, and 50 ppm. Qualitative data were processed descriptively, quantitative data were analyzed based on ANOVA. The results showed that the use of Gibberellins with a concentration of 10 ppm and the maintenance of Stevia cuttings in clear plastic containers were more effective in the development of an average stem length of 19.18 ± 2.40, a mean plant length of 23.62 ± 2.34 and an average number of roots 14, 33 ± 2.32.

Abstract

Natural-based antidiabetic drugs need to be developed as an alternative to synthetic antidiabetic drugs to minimize side effects. Suruhan extract (Peperomia pellucida) is one of the natural ingredients that has antidiabetic activity. In vitro studies show that ethanol extract, hexane extract and purified ethanol extract have antidiabetic effectiveness. This study was conducted to test the antidiabetic activity of purified suruhan extract on alloxan-induced Wistar rats to confirm antidiabetic activity in vivo. A total of 8 test groups, each consisting of 3 rats induced by alloxan 125mg/KgBW and non-fasting blood glucose was checked at 0; 30; 60; 90; 120; and 150 minutes using a glucometer, then the percentage of decrease in blood glucose levels was calculated. Positive control using glibenclamide 0.45mg/KgBW, negative control using CMC-Na 0.5%. The treatment groups consisted of: Extract 20mg/KgBW (E20); Extract 40mg/KgBW (E40); Extract 80mg/KgBW (E80); Purified Extract 20mg/KgBW (P20); Purified Extract 40mg/KgBW (P40); and Purified Extract 80mg/KgBW (P80). Results showed the percentage decrease in blood glucose levels of E20; E40; E80; P20; P40; and P80 respectively: 39.93%; 42.29%; 46.93%; 38.34%; 55.34%; and 66.40%. The percentage decrease in blood glucose levels of the positive control group was 53.71%. The Purified Extract treatment groups of 40mg/KgBW and 80mg/KgBW showed the percentage decrease in blood glucose levels equivalent to and better than the positive control of glibenclamide 0.45mg/KgBW (p<0.05%). The purified extract was shown to have antidiabetic effects in vivo and is promising for use as an alternative antidiabetic drug.

Abstract

The world's elephant population is experiencing a significant decline and is a serious concern in conservation efforts. Conflicts between elephants and humans are becoming an increasingly widespread problem, especially on the island of Sumatra. This study aims to assess people's perceptions of elephant conflicts, the impacts and the education needed to increase public awareness of the importance of elephants. Through the literature study method, it is known that people's perception of elephant conflict tends to be negative, most people have the perception that elephants are crop pests and must be destroyed. The impact of conflicts between elephants and humans such as damage to agricultural land, death of elephants and humans, and damage to infrastructure. To realize a solution to this conflict, it is necessary to conduct comprehensive educational counseling to the community, such as the implementation of a moratorium on concession licensing, forest enrichment, the formation of effective patrol teams, technological support in monitoring forest changes, and socialization to surrounding communities about elephants. Collaboration between the government, communities, and non-governmental organizations will be beneficial in addressing human-elephant conflicts. With these efforts, it is hoped that disputes between elephants and humans can be minimized and the increasingly threatened elephant population will be maintained and sustainable.

Abstract

River water pollution is caused by waste, particularly bacterial contamination resulting from a variety of waste types generated by community activities on the river coast. Stream water that is sullied with microbes, whenever utilized reasonably, will be exceptionally risky for the strength of stream seaside networks. The most elevated instances of looseness of the bowels were in Katingan Rule at 4,920 individuals/year. This research aims to determine the type and value of coliform bacterial contamination in the waters of the Katingan River, Kasongan Lama Village, Katingan Hilir District. This research uses quantitative methods. The Katingan river water is cloudy brown, has no aroma, has a turbidity value of 50, which is strongly suspected to be high turbidity, and has a water pH of 3.3, which is strongly suspected to be acidic. All examples from the examination results were positive with a typical MPN worth of >1100 MPN/g and had a place with bar molded gram-negative microbes (bacilli) and were thought to be explicitly Escherichia Coli. The experimental outcomes show that the waters of the Katingan Stream, Kasongan Lama Town, Katingan Hilir Region, are decidedly defiled with coliform microscopic organisms and have passed the edge for class 1 waterway prerequisites (1000 MPN/g).

Abstract

Orange-footed scrubfowl (Megapodius reinwardt) is a protected animal. Especially on the island of Lombok, one of the habitats of the orange-footed scrubfowl bird is in Tunak Montain Nature Tourism Park. The condition of the nest will influence the frequency of presence of orange-footed scrubfowl. In this regard, to enrich information in its conservation, it is necessary to carry out research on the characteristics of the nests of the orange-footed scrubfowl. The aim of this research to determine the nest characteristics of the orange-footed scrubfowl in Tunak Montain Nature Tourism Park. The method used is direct measurement and observation in the field. The results of the research show that the nest of the orange-footed scrubfowl bird is in the form of a mound of earth composed of leaves, branches, tree twigs, sand and rocks. The height of the nest mound ranges from 57-160 cm, and the diameter of the nest mound is 500-1,030 cm. The number of holes in each nest varies, namely between 5-9 holes, with a hole depth of 67-142 cm and a nest hole diameter of 30-41 cm. The dominant factors of the abiotic component of the nest that have a singular influence on the presence of orange-footed scrubfowl are distance to the river channel and number of predators. The tendency to choose a nesting area based on the results of Chi-Square analysis is influenced by five variables, namely, distance to the river, soil texture, altitude, temperature and number of predators around the nest.

Abstract

The COVID-19 virus, which is caused by SARS-CoV-2, is a global health problem that affects many nations. Similar to the H7N9, SARS, and MERS viruses, COVID-19 can be more severe in hypertensive individuals. With a prevalence of 50.1% among COVID-19 patients, hypertension is a significant comorbidity that increases the risk of death by 1.37 times due to the increased number of ACE2 receptors that facilitate the virus's spread. This study uses a descriptive cross-sectional design with secondary data from medical records of COVID-19 patients with hypertension at Rumah Sakit Ibnu Sina Makassar. Data were collected through total sampling after obtaining permission from the hospital and then processed and analyzed descriptively. The study shows that the majority of COVID-19 patients with hypertension are aged 65 and over (33.4%). Male patients are slightly more prevalent (53%) compared to females (47%), possibly due to genetic factors affecting the immune system. Seventy-three percent of patients adhered to hypertension treatment, while 27% did not. The function of the ACE-2 enzyme, which is also affected by antihypertensive treatment, may have an impact on the relationship between COVID-19 and hypertension. These findings emphasize the significance of treating the elderly and remaining on treatment in order to reduce the likelihood of contracting COVID-19. The survey derives that the vast majority of Covid patients with hypertension are developed 65 and over (33.4%), with an insignificantly higher inescapability of folks (53.3%) diverged from females. Adherence to hypertension treatment is high, with 73.3% of patients following their prescribed regimen.
