Abstract

One of the ecosystems found in coastal areas is the mangrove ecosystem. Mangroves have many functions including as a shelter, a place to find food, a breeding ground for aquatic biota. Damage to mangrove areas can cause a decrease in the quality of mangrove ecosystems, especially for the life of mangrove crabs. Mud crab is one of the aquatic biota associated with mangroves and its life is influenced by the presence of mangrove forests. Therefore, the purpose of this study was to determine the diversity of mud crabs that live in mangrove ecosystems and the association of mangrove species with several species of mud crabs in the coastal mangrove ecosystem of Lembar, West Lombok. Mud crab samples were taken using purposive sampling by looking at the density of mangroves in each observation plot. The collected data were analyzed by diversity index, ecological index, association and Pearson's correlation coefficient. Then a simple linear regression analysis was performed with the variable (x) density of mangroves and (y) density of mangrove crabs. The results of this study were found to be 10 species of mud crabs consisting of 2 families of Ovalipidae and 8 families of Portunidae which belong to the moderate diversity index. There were 2 species of mud crabs that were positively associated with 2 species of mangroves out of 10 species of mud crabs found. Linear regression equation y = 0.2482x + 0.0004 with a pearson correlation coefficient (r²) (0.58).

Abstract

Mangroves have a function as shelters, nurturing places, spawning grounds, and foraging places, and can be a habitat for wild animals. Brachyura is one of the mangrove biota associations whose lives are influenced by the existence of mangroves. Therefore, the purpose of this study is to determine the diversity of crabs (Brachyura) and the relationship between mangrove density and crab abundance (Brachyura) in the coastal mangrove area of Gerupuk Beach Central Lombok. The crabs (Brachyura) sampled were Brachyura contained in the observation plot, Brachyura on the surface of the substrate was taken by hand, while those in the hole were taken with the help of a shovel. The data obtained were then analyzed with the Pearson diversity index, association, and correlation coefficient. Furthermore, a simple linear regression analysis was carried out with the independent variable (x) mangrove density and the dependent variable (y) crab abundance (Brachyura). The results of this study obtained 7 species of Brachyura consisting of 6 species of the family Ocypodidae and 1 species of the family Grapsidae. The Brachyura diversity index at the research station was moderate to high with values between 1.7-4.0. Furthermore, there are 3 species of crabs (Brachyura) associated with 2 species of mangroves out of 7 species of Brachyura found. The linear regression equation y= 0.2619x + 0.0206 with a pearson correlation coefficient value (r) of 0.79 shows a strong relationship between the variable independek (x) mangrove density and the dependent variable (y) Brachyura abundance. The conclusion of this study is that Brachyura diversity in the Gerupuk Beach mangrove area is included in the medium category and there is a significant relationship between mangrove density and Brachyura abundance

Abstract

The sperm sexing technique is the separation of spermatozoa carrying the X chromosome and the Y chromosome, which allows farmers to choose male births for beef cattle businesses. However, the process of centrifugation and sperm preservation can cause oxidative stress which gives rise to free radicals. Therefore, an antioxidant ingredient is needed in the diluent, including noni fruit extract which contains lots of flavonoids. This research aims to analyze the addition of noni fruit extract in a diluent to improve the quality of Y-chromosome spermatozoa at a storage temperature of 5oC. The results of the study showed the results of analysis of the progressive motility of Y-chromosome spermatozoa, showing a decrease in progressive motility, on D7 and D-9 there was a difference between control vs P1 and P2 (P<.05) respectively 37.63% vs 49.96% vs 48.56%, while on day 11 showed a very real difference between P0 vs P1 vs P2 respectively 24.32% vs 36.77% vs 40.87%. The addition of 3% and 5% noni extract can improve the quality of Y spermatozoa stored at 5oC. This is because noni extract contains amino acids, ascorbic acid, and flavonoids as antioxidants so that it is able to prevent free radicals, scavengers, and damage to the spermatozoa plasma membrane can be prevented. The addition of 5% noni fruit extract in the diluent to improve the quality of Y-chromosome spermatozoa at a storage temperature of 5oC for up to 11 days.

Abstract

Cases of Dengue Hemorrhagic Fever (DHF) in Bima City are of concern because of its widespread spread and the number of sufferers continues to grow. The Municipal Government of Bima, West Nusa Tenggara, has established an Extraordinary Event (KLB) status for DHF. This status was assigned as a response to the high increase in DHF cases over the past two months, namely January and February 2023. Although vector control efforts have been made, DHF cases continue to fluctuate and increase significantly in early 2023. Therefore, researchers have conducted a Quick Response Analysis of DHF cases in Bima City with the aim of providing information about DHF cases and analyzing this information, as well as developing recommendations for alternative solutions in preventing an increase in DHF cases in Bima City. Through the descriptive method, it was found that the incidence of DHF in Bima City tends to increase significantly at the beginning of 2023 compared to the previous two years, with 172 positive cases and 4 of them leading to death as of February 10, 2023. One of the things of concern based on the case analysis is the understanding and attitude of the community regarding environmental sanitation. Meanwhile, solutions that can be recommended are in the form of short, medium, and long term recommendations which can be used as a reference for consideration in establishing regulations to control dengue fever

Abstract

This study aims to determine how learning to play roles and simulations affects critical thinking skills and student character building. This study is quantitative and of the quasi-experimental variety. 38 MTsN 1 Palu City ninth graders were employed in this study. Data were gathered for this study using observation sheets for students' character development during the learning process and exams in the form of descriptions of critical thinking abilities. Descriptive and inferential statistics are used in the data analysis for this study. The study's findings demonstrate a considerable impact of simulation and role-playing learning models on students' critical thinking abilities. Students in the experimental class who were instructed using simulation and role-playing learning models scored, on average, better than those in the control class. The ability of students to formulate the main issues is the best sign of critical thinking abilities. The study's findings also demonstrate a considerable impact of simulation and role-playing learning techniques on student character development. Students in the experimental class who were instructed using role-playing learning simulations and models had an average value of character-building observations greater than those in the control class. Religious and creative activities are the best predictors of character development.

Abstract

The prevalence of anemia in adolescents at the national level is still considered quite high. Several factors are associated with the incidence of anemia in female adolescents, namely energy intake, protein intake, iron intake, vitamin C intake, tea or coffee drinking habits, investment in worms, knowledge, education and type of parental occupation, family income, and menstrual patterns as well as genetics. Stunting is also still a problem in Indonesia due to insufficient nutritional intake for quite a long time. Stunting occurs when the fetus is still in the womb and only appears when the child is two years old. anemia caused by malnutrition at an early age increases infant and child mortality. anemia in young women and also stunting in children is very dangerous. Where the purpose of research is to explain Genetic Factors Causing the Prevalence of Anemia in Young Girls and Stunting in Toddlers. A review is conducted on the state-of-the-art methods using the preferred reporting items for reviews and meta-analyses (PRISMA) guidelines. We review literature from several publications and analyze genetic factors that cause the prevalence of anemia in young women. The prevalence of anemia among young women is also caused by genetic factors. Young women tend to experience anemia because during this period they experience growth and development. The risk of anemia increases with physiological shifts such as menstrual periods. To prevent anemia, the government has planned a program for the Prevention and Control of Iron Nutrition Anemia in women of childbearing age which aims to reduce the prevalence of iron deficiency anemia in high school and junior high school students.

Abstract

This research was conducted at the Research Barn in Pengawu Village, South Palu Subdistrict, Palu City, Central Sulawesi Province, for 10 weeks, starting from May 19, 2014, to August 11, 2014. The aim of this study was to determine the carcass component weight of female Kacang goats fed at different times. Fifteen female Kacang goats, aged approximately 10 to 12 months and weighing between 10.20 to 16.00 kg, were used for the study. These goats were sourced from local farmers in Palu City and its surrounding areas. Each goat was placed in an individual pen with dimensions of 75 x 75 x 75 cm, and there was a total of 15 individual pens, each equipped with a feeding and drinking trough. The study used a Randomized Block Design (RBD) with five treatments and three blocks as replications. The five different feeding times were as follows: WM1 = Feeding at 08:00 WITA, WM2 = Feeding at 09:30 WITA, WM3 = Feeding at 11:00 WITA, WM4 = Feeding at 12:30 WITA, and WM5 = Feeding at 14:00 WITA. The results of the analysis of variance (ANOVA) showed that feeding at different times had a highly significant effect (P<0.01) on the carcass weight of female Kacang goats in the neck, ribs, and legs. It also had a significant effect (P<0.05) on the carcass component weight in the shoulder, loin, flank, and breast, but it did not have a significant effect (P>0.05) on the carcass component weight in the arm
