Eggs are a food ingredient with a relatively high protein content and have complete amino acids, unsaturated fats, vitamins and minerals that the body needs and are easy to digest. Eggs are always available throughout the year, but the fact is that egg shells crack easily, relative humidity and temperature in the storage room can affect the quality of eggs and cause chemical and microbiological changes so preservation efforts are needed to maintain the quality of the eggs. Salted eggs are a way to preserve eggs which has the benefit of improving the taste and the texture of the egg yolk. The addition of kaffir lime leaf flour is one of the diversification methods for processing salted eggs. The aim of this research was to determine the sensory characteristics of salted eggs by administering kaffir lime leaf flour. The experimental research used a Completely Randomized Design (CRD) with 5 treatments, namely S0: 0% kaffir lime leaf flour, S1: 15% kaffir lime leaf flour, S2: 20% kaffir lime leaf flour, S3: 25% kaffir lime leaf flour, and S4: 30% kaffir lime leaf flour with 5 repetitions. he results of the research showed that salted eggs with 25% kaffir lime leaf flour produced salted eggs that were liked by the panelists in terms of sensory characteristics.

Hypertension is a medical condition characterized by elevated blood pressure beyond normal limits. Management strategies for hypertension can be pharmacological or non-pharmacological. This study aims to evaluate the effect of administering "semundu" juice combined with yogurt on reducing blood pressure in individuals with hypertension in the Jembatan Kecil Health Center area, Bengkulu City, in 2024. A total of 28 participants with high blood pressure were randomly assigned to one of four groups: P0 (control group receiving educational leaflets), P1 (200g watermelon juice, 100g cucumber, and 20ml honey), P2 (100g Ambon banana, yogurt), and P3 (200g watermelon juice, 100g cucumber, 20ml honey, and yogurt). The Kruskal-Wallis test results indicated that the administration of "semundu" juice combined with probiotics significantly affected both systolic and diastolic blood pressure, as evidenced by a p-value of less than 0.05. All treatment groups demonstrated a reduction in blood pressure, with significant differences observed between the groups: P0 vs. P3 (p-value < 0.02), P1 vs. P3 (p-value < 0.034), and P2 vs. P3 (p-value < 0.01). These findings suggest that "semundu" juice combined with probiotics has a notable impact on lowering blood pressure in individuals with hypertension.

This study aims to determine the effect of heat moisture treatment (HMT) duration and lactic acid concentration on the characteristics of purple sweet potato flour (Ipomoea batatas L. Poiret). The method consisted of two stages, namely preliminary stage to produce control (unmodified) flour and main stage to produce modified flour. The method used was a randomized group design with a factorial pattern of 3 x 3 and 3 replications. The variables used were HMT duration (3, 5, and 7 hours) and lactic acid concentration (200, 400, and 600 ppm). The parameters observed in the main stage were water content, anthocyanin level, swelling power, color, solubility, and flour gelatinization profile or Rapid Visco Analysis (RVA). The results show that HMT duration affected the water content and solubility of the modified purple sweet potato flour. HMT duration of 7 hours and lactic acid concentration of 600 ppm resulted in flour anthocyanin level of 24.046 mg/kg. The gelatinization profile shows that the modified purple sweet potato flour experienced the initial temperature of gelatinization (pasting temperature) at 92.30ºC, peak viscosity at 1,343 cP, hot paste viscosity (hold viscosity) at 362 cP, cold paste viscosity (final viscosity) at 931 cP, breakdown (viscosity stability during heating) at 381 cP, and seatback (changes in viscosity during cooling) at -31 CP.

The problem of stunting in Indonesia is still quite high, namely 21,6% based on data from the 2022 Indonesian Nutrition Status Survey (SSGI). One of the effective measures to control stunting is through providing additional food (PMT) such as biscuits to children. Carrots and pumpkin are local foods that are rich in beta carotene. Carotenoids as a source of provitamin A are able to overcome the problem of vitamin A deficiency (VAD), which is the cause of growth disorders in children. This research aims to determine the effect of substitution of yellow pumpkin (Cucurbita moschata) and carrot (Daucus carota L.) composite flour on organoleptic characteristics including color, aroma, taste, texture and nutritional content (beta carotene, carbohydrates, protein and fat). This research used a Randomized Block Design (RAK) with 3 treatments, namely formula 1 (150 grams of wheat flour, 50 grams of pumpkin flour and 50 grams of carrot flour), formula 2 (50 grams of wheat flour, 60 grams of pumpkin flour and 50 grams of flour carrots) and formula 3 (50 grams of wheat flour, 50 grams of pumpkin flour and 150 grams of carrot flour) with 3 repetitions. The research results showed that formula 3 biscuits were the best formulation in terms of organoleptic characteristics with the highest beta carotene content compared to F1 and F2. F3 biscuits contain 30,97 mg beta carotene, 7,45 grams of carbohydrates, 3,22 grams of protein and 8,89 grams of fat. The conclusion of this research is that the substitution of wheat flour with composite flour (Cucurbita moschata and Daucus carota L.) has an effect on the nutritional content (beta carotene, carbohydrates, protein and fat) of biscuits. Consuming pumpkin biscuits per 100 grams can qualify as a good source of the antioxidant beta carotene.
