Abstract

Diabetes Mellitus (DM) is a metabolic disease characterized by hyperglycemia caused by defects in insulin secretion, insulin action, or both. The number of people with DM has increased to approximately 463 million individuals aged 20-79 worldwide. Several complications can arise due to DM, one of which is gangrene wounds. Gangrene wounds are the most common microvascular complication in DM patients. Nutritional intake is a crucial component in the wound healing process. The aim of this study is to determine the relationship between diet and the degree of gangrene in DM patients. The method used is an observational analytical approach with a cross-sectional design. The sample size consists of 51 respondents obtained from medical records and questionnaires filled out by DM patients. Data analysis was conducted using the Chi-Square test. The results showed that 23 respondents had a moderate diet (45.1%), and the majority of respondents had wounds classified as degree 3 (21.6%). A significant relationship was found between diet and the degree of gangrene in DM patients (p<0.005). Thus, it can be concluded that a significant relationship exists between diet and the degree of gangrene in DM patients

Abstract

Macroalgae are photosynthetic organisms that grow in aquatic environments and play an important role in marine and coastal ecosystems. Macroalgae grow in almost all waters, including in the coastal area of Batu Layar. Batu Layar has particular and distinctive characteristics compared to other locations on Lombok Island. However, in recent years, supporting tourism facilities have begun to be built which will affect the composition of living biota including macroalgae. Therefore, data was collected on the diversity of changes in the composition of macroalgae in the future. This study aims to determine the diversity of macroalgae growing on Batu Layar Beach, West Lombok. This study is a descriptive exploratory study. Quadrant placement and sampling were carried out using the purposive sampling method. The results showed that the number of species growing in Batu Layar waters was 41 species. These species are spread across two observation stations. Station 1 is dominated by S. polycystum while station 2 is dominated by P. australis. The current strength and depth parameters of Station 1 were higher than those of Station 2, while the ammonia, phosphate and turbidity of Station 2 were higher than those of Station 1.

Abstract

Carrageenan is widely used in various industries, such as food and beverages, cosmetics, and pharmaceuticals, due to its important role as a viscosity regulator, stabilizer, thickener, developer, gelling agent, and excellent stabilizing agent. Temperature and drying duration are important factors that affect the quality of the final product. This study aims to examine the quality characteristics of carrageenan from Eucheuma spinosum dried using the oven method, considering variations in temperature and drying time. This study used a completely randomized design (CRD) with two factors: temperature and drying time, each of which was repeated three times. Eucheuma spinosum was extracted using the microwave-assisted extraction (MAE) method with 10% KOH solvent in a ratio of 1:10 for 8 minutes. The first factor is the drying temperature, which consists of three levels: 40°C, 50°C, and 60°C. The second factor is the drying time, which also consists of three levels: 24 hours, 27 hours, and 30 hours. The results of the study showed that (1) temperature and drying time affect the quality characteristics of carrageenan from Eucheuma spinosum dried using the oven method, (2) the parameters affected include water content, ash content, sulfate content, viscosity, and gel strength of carrageenan, and (3) the higher the temperature and duration of drying, the more the water content, ash, protein, and crude fiber in the product tend to decrease. This decrease is in line with the viscosity and gel strength of the resulting carrageenan.

Abstract

Robusta Coffee Leaves are known to have high antioxidants that can stabilize free radical attacks. Based on the height of the place where Robusta Coffee grows, it has different characteristics, including producing different qualities and flavors from one another. This study aims to determine the content of phytochemical compounds and the antioxidant activity of Robusta coffee leaves based on differences in the height of the place where it grows. The research method used was sampling at several heights including 511 masl, 434 masl, 354 masl, 204 masl, 122 masl, and laboratory research for phytochemical and antioxidant tests. Data analysis used the ANOVA, DMRT, and Bivariate correlation tests to determine the correlation between height and antioxidant activity. The results showed that all five heights contained alkaloid and flavonoid compounds. The highest inhibition of antioxidant activity was found at an altitude of 511 masl with a percentage of 61.89% ±8.08b, while the lowest inhibition of antioxidant activity was found at an altitude of 122 masl with a percentage of 31.92% ±7.38a. Antioxidant activity at all five altitudes is classified as a very strong antioxidant with an IC50 value <50. Altitude has a significant effect (P<0.05) on antioxidant inhibition. Altitude has a positive correlation with antioxidant activity.

Abstract

This study aims to determine the effect of plant growth regulators and seed cutting patterns on the induction of mangosteen shoot growth. The research was conducted at the YAHDI Tissue Culture Laboratory in Medan, North Sumatra, Indonesia, in 20245. The method used in this study was a Completely Randomized Design (CRD) with two factors: BAP concentration and seed cutting pattern. The data collected were analyzed using statistical analysis of variance (ANOVA) with Duncan's Multiple Range Test (DMRT) at a 5% significance level using SPSS 26. The results of the study show that the interaction between BAP concentration and seed cutting pattern significantly affected the time of shoot emergence, the number of leaves, and the shoot height. The best shoot emergence time was obtained with a BAP treatment of 4 mg/L using whole seed explants, which occurred at 1 MST (Month After Sowing). A BAP concentration of 2 mg/L with whole seed explants produced the highest number of leaves, with 8 leaves. The highest number of shoots was obtained from explants planted in a medium with 6 mg/L BAP, which resulted in 5.67 shoots. Whole seeds planted in a medium with 0 mg/L BAP produced the tallest plants, measuring 8.9 cm. The combination of BAP concentration and seed cutting pattern did not significantly affect the number of roots.

Abstract

Teaching materials in the form of electronic learning modules really help students and teachers in understanding a learning flow or process. E-Module is a digital learning media that is arranged systematically so that students can learn independently. This research aims to see differences in use of e-module Biodiversity containing Sumba's local potential based on guided inquiry with the JAS approach to increase students' environmental literacy in high school biology material. This study is a Research and Development (R&D) with the Lee & Owens (2004) model. The research population was all class X students of SMA Negeri 6 Malang for the 2024/2025 academic year. The sample in this study was 33 students for the experimental class and 37 students for the control class. Environmental literacy analysis uses the ANACOVA test with a significance level of 5%. The results of the study showed that in the ANACOVA test a significance value of 0.008, which means it is smaller than α 0.05 (Sig < 0.05). This confirms that there are significant differences between the classes that use it e-module and those who do not, so that it has an effect on increasing students' environmental literacy. Thus, it can be concluded that the use of e-module Biodiversity containing Sumba's local potential based on guided inquiry using the JAS approach can influence and increase students' environmental literacy.
