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 still a major nutritional problem faced by the Indonesian people. From the results of the previous PKM, in RW 17 Kemirimuka there were still cases of stunting 11.11% of toddlers who attended the activity. One effort that can be made to reduce the incidence of stunting is to provide functional foods such as Moringa leaves (Moringa oleifera). Moringa leaves have high vitamin C, calcium, beta-carotene, potassium and protein content, this PKM aims to provide counseling, demonstration of making functional food from Moringa leaves and anthropometric measurements in monitoring the nutritional status of toddlers at Posyandu Cempaka RW 17 Kemirimuka Village, Beji District, Depok. The 4-stage counseling method is a lecture, demonstration of making pudding from Moringa, filling out a questionnaire about the organoleptic of pudding, and measuring the anthropometry of toddlers. Based on filling out the questionnaire, it is known that making pudding from Moringa leaves is easy to do with simple and easily obtained ingredients, has a delicious taste and an attractive shape so that it is liked by toddlers. The results of anthropometric measurements show that most toddlers at Posyandu Cempaka RW 17, Kemirimuka Village, Beji District, Depok City-West Java have good (normal) nutrition and no toddler respondents were found to have poor/bad nutrition and there was no stunting.

Abstract

Black rice (Oryza sativa L. indica) is a variety of pigmented rice that, apart from acting as a popular food ingredient, can also be used for health because it has active compounds that have the potential to act as antioxidants. The research carried out aimed to determine antioxidant potency, conduct secondary metabolite screening, and characterize the active compound content of black rice extract. It was macerated using a 96% pro-analysis (p.a.) ethanol solvent. Antioxidant potency was tested using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) methods, secondary metabolite screening using the Harbone method, and identification of active compounds using Gas Chromatography-Mass Spectrometry (GC-MS). It was found that black rice extract has potential as an antioxidant, using the DPPH method, the 50% Inhibition Concentration (IC50) value of black rice extract and vitamin C was 97.34 ppm and 2.64 ppm, respectively, but using the FRAP method, the IC50 values of black rice extract and vitamin C were 181.83 ppm and 7.84 ppm, respectively. Secondary metabolite screening detected that in black rice extract there were active compounds in the flavonoid and steroid groups, GC-MS identification results showed that the extract contained the most compound, hexadecanoic acid.

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.

Abstract

Jamu Susut Perut is a traditional Indonesian herbal preparation widely used as a complementary therapy to support weight loss and reduce abdominal fat. It commonly contains medicinal plants such as Guazuma ulmifolia (Jati belanda), Curcuma longa (Turmeric), Zingiber purpureum (Bangle), Murraya paniculata (Kemuning), Orthosiphon aristatus (Cat’s whiskers), Gallae (Majakanis), Areca catechu (Betel nut), and Piperis folium (Betel leaf). These plants are rich in bioactive compounds including flavonoids, polyphenols, alkaloids, and saponins, which possess lipolytic, anti-inflammatory, and hepatoprotective properties that may enhance fat metabolism and lower blood lipid levels. This study aims to identify the phytochemical compounds in Jamu Susut Perut (X) using the Harborne method and to determine its toxicity against shrimp larvae (Artemia salina Leach) through the Brine Shrimp Lethality Test (BSLT). The LC₅₀ (lethal concentration 50%) value was calculated using probit analysis in SPSS and Microsoft Excel. The phytochemical screening revealed the presence of triterpenoids, quinones, flavonoids, and saponins in the herbal formulation. The toxicity test showed that Jamu Susut Perut (X) had an LC₅₀ value of 547.92 ppm, indicating toxicity to shrimp larvae since the value is below 1000 ppm. In conclusion, Jamu Susut Perut (X) contains bioactive compounds with potential pharmacological effects but also exhibits toxic properties at certain concentrations. This research provides scientific data to ensure the safe use of Jamu Susut Perut as a traditional herbal medicine for consumers.
