Abstract

Hypertension is a condition in which systolic blood pressure reaches or exceeds 140 mmHg and diastolic blood pressure reaches or exceeds 90 mmHg. The purpose of this study was to evaluate the effect of giving black grass jelly (Premna oblongifolia Merr) ice to pregnant women with hypertension. The method used in this study was a pre-experimental design with a One Group Pretest Posttest using a cross-sectional time approach. The research population consisted of 20 respondents, with a sample of 10 respondents selected using purposive sampling method. The results of this study concluded that giving black grass jelly ice has a positive effect, especially as an effective non-pharmacological method in reducing blood pressure in pregnant women who experience hypertension. These findings indicate that giving black grass jelly ice can be an effective alternative in managing blood pressure in pregnant women with hypertension. This method holds promise as an adjunctive therapy that can reduce the risk of complications related to hypertension in pregnant women.

Abstract

Introduction. Iron-deficiency anemia is a hematological disease that is often found in pregnant women. This situation can certainly hinder the growth and development of the fetus in pregnant women. It can be said to be anemia if the number of red blood cells or hemoglobin is below the normal limit if the hemoglobin level is <14 g/dL in men and <12 g/dL in women. Therefore, food that contains iron is needed to meet daily iron needs. Sorghum planting is often found in East Java and surrounding areas. This plant contains high levels of iron compared to other cereals, such as rice. This research aims to determine the effect of sorghum flour substitution on the organoleptic acceptability of sorghum white bread. Metode. The analysis used in this research consists of static analysis and organoleptic analysis. Result&Analysis.The results of this study showed that there was a significant effect on the color, smell, flavor, and texture of white bread substituted for sorghum kurskal wallis flour (p > 0.005).Discussion. This research concludes that white bread substituted for sorghum flour influences organoleptic quality.

Abstract

This study aims to formulate fruit detachment dynamics as the core concept for designing a selective vibratory mechanical harvester for robusta coffee. Plant-level average fruit removal force (FRF) and fruit mass data from five coffee plants were analysed for three maturity classes identified by color: red, orange, and green. An empirical FRF model was built using maturity code and fruit mass as predictors, after which a dynamic force model based on forced vibration, Fd = mA(2?f)², was used to simulate detachment behavior under different operating conditions. Model validation employed goodness-of-fit statistics and leave-one-out cross-validation, while selective harvesting performance was predicted through maturity-specific detachment probability curves. Mean FRF increased consistently with decreasing maturity, from 3.532 N in red fruits to 5.966 N in orange fruits and 8.034 N in green fruits, whereas fruit mass varied only slightly among stages. The empirical model showed high predictive accuracy (R² = 0.997; RMSE = 0.095 N), indicating that maturity status dominated the FRF response. Simulation results demonstrated that, at a vibration amplitude of 3 mm, equivalent threshold frequencies were approximately 99.9 Hz for red fruits, 129.9 Hz for orange fruits, and 151.3 Hz for green fruits. An optimum selective operating window of 3.60-5.91 N, equivalent to 101.0-129.4 Hz, was identified for maximizing ripe-fruit recovery while maintaining high harvest purity.
