Abstract

Malnutrition is still a major problem in infants and children globally. Data from the World Health Organization (WHO) for 2020 shows that the prevalence of stunting globally is in the high category because it is between 20% - 30%. Indonesia is the sixth country in the South-East Asia region with 36,4% of stunting cases. Incidence of stunting occurs due to chronic malnutrition in children after birth. Malnutrition can occur as a result of a child after birth getting insufficient food or breast milk for growth. Therefore it is necessary to do various ways to prevent the incidence of stunting in the community, one of the efforts is through counseling to prevent stunting by using herbal ingredients to increase breast milk and monitoring the nutritional status of toddlers through anthropometric measurements. Community service activities carried out included counseling on stunting prevention and anthropometric measurements at Posyandu Cempaka RW “A”, Kemirimuka Village, Beji District, Depok City, JABAR. Based on the results of anthropometric measurements, based on weight and height, it is known that most of the respondents who came to Community servicetivities were normally and excess nutritious, but there were respondents who were stunted.

Abstract

Stunting is a form of growth failure (growth faltering) due to the accumulation of nutritional deficiencies that last for a long time starting from pregnancy until the age of 24 months. Optimal nutritional intake for newborns by providing exclusive breast milk as the main food until the age of 6 months and then continuing until the age of 2 years accompanied by appropriate and high-quality complementary foods will prevent stunting in toddlers. One important effort to prevent stunting is by empowering the community, especially parents, to pay attention to the intake of breast milk and complementary foods for their babies. By providing knowledge to the public about the importance of correct breastfeeding and MPASI, it is hoped that the public can change their behavior to prioritize exclusive breastfeeding and correct MPASI. This community service method uses an educational approach through outreach with a total of 139 participants who live in five villages in Jatigede District, Sumedang Regency, West Java. Socialization involving experts gave results that there was an increase in participants' knowledge as measured using pre-test and post-test instruments. The percentage of participants who experienced an increase in knowledge from 139 participants, the results obtained were 118 participants (85%) experienced an increase in knowledge about breast milk and complementary foods, and 19 people (14%) had the same knowledge before and after socialization while 2 people (1%) gained The score decreased during the post-test due to several factors, including some participants who did not have time to complete the post-test questionnaire due to having to do other work

Abstract

Diabetes mellitus is a global health challenge characterized by an ever-increasing number of cases annually. The most feared chronic complication of diabetes mellitus is diabetic foot ulcer (DFU), which significantly increases the risk of amputation and mortality rates. This study aims to analyze the relationship between random blood sugar (RBS) levels and the incidence of DFU in type 2 diabetes mellitus patients at Paragon Hospital, Citeureup 2026. The research method used is an analytical observational design with a cross-sectional approach. A total of 54 subjects meet the inclusion criteria out of 109 type 2 diabetes mellitus patients. Medical record data were statistically analyzed using the Chi-Square test. The results indicated that DFU patients were predominantly male (53.7%) and belonged to the 46-55 age group (38.9%). Clinical findings showed that the majority of research subjects (88.9%) had high random blood sugar levels (≥ 200 mg/dL). Statistical test results yielded a p-value of 0.000 (p < 0.05), indicating a significant relationship between high RBS levels and the incidence of DFU. Based on the result the concluded that uncontrolled RBS levels are a primary trigger for DFU. Chronic hyperglycemia triggers vascular and nerve damage, which inhibits the tissue healing process in the feet. Optimal control of RBS levels is essential as a preventive measure to avoid amputation complications in type 2 diabetes patients.

Abstract

Oxidative stress is one of the causes of heart disease, atherosclerosis, and cancer. Efforts to overcome oxidative stress include the use of natural antioxidants. Flavonoids and phenolics are secondary metabolite compounds in plants that have antioxidant activity. Plants that are believed to be able to overcome oxidative stress include Kebar grass. Kebar grass (Biophytum umbraculum) is one of the plants that empirically has many benefits including as a female fertility drug by the Kebar-Papua community. The study aimed to determine the antioxidant potential and total phenolic and flavonoid content of Kebar grass extract. Kebar grass extract was obtained through maceration extraction with 96% pro-analysis (p.a) ethanol solvent. Antioxidant testing used the 2.2-diphenyll-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) methods using antioxidant standards, namely ascorbic acid (vitamin C) and gallic acid, while measuring total phenolic and flavonoid levels used the Folin-Ciocalteu and aluminium chloride methods, respectively. The results showed that the total phenolic and flavonoid levels of Kebar grass extract were 52.26 ± 3.94 mg GAE/g dw (dry weight) and 22.15 ± 2.79 mg QE/g dw Kebar grass extract, respectively, while the antioxidants of Kebar grass extract with the DPPH method had an inhibition concentration 50 (IC50) value of 183.44 ppm and a vitamin C standard of 4.46 ppm, and antioxidant testing using the FRAP method obtained a reducing power 50 (RP50) value of Kebar grass extract of 5043.76 ppm with a gallic acid standard value of 101.8 ppm.
