Abstract

Hunger is a condition of food insecurity. One of the efforts that can be made to reduce the incidence of food insecurity is to maintain food security, especially in households. This is an analytic observational study with a cross-sectional design with a random sample of 60 households in Caringin district, Bogor regency. Assessment of household food availability was based on a food availability questionnaire consisting of several types of food groups. Income and expenditure were measured by assessing household income. The condition of household food diversity was measured using the HDDS questionnaire. The chi-square test was used to analyze the relationship between consumption behavior, income, household expenditure, and household food security. There was a relationship between income (p=0.00) and expenditure (p=0.00) with household food security, while consumption behavior is not (p=0.14). It is concluded that there was a relationship between income and expenditure on food security, but behavior did not show an insignificant relationship. There needs to be an in-depth analysis to find other factors influencing food security apart from the variables examined in this study.

Abstract

The research aims to produce innovative soft candy from goat's milk and annatto extract as colorants and antioxidants that consumers like. Soft candy product innovations were studied in random group designs consisting of five concentrations of annatto extract (0%, 0.15%, 0.20%, 0.25%, and 0.30%). The results showed that the addition of annatto extract in the goat's milk soft candy formula decreases the L value, along with an increase of a* and b values so that the color of the soft candy becomes orange. Increasing the concentration of annatto extract causes a significant increase in antioxidant activity. The addition of annatto extract in the goat's milk candy formulation influenced the level of preference for the color attribute but did not affect the aroma, taste, and texture attributes. The goat's milk soft candy with the addition of 30% annatto extract as a natural colorant and antioxidant produced the best physicochemical and sensory characteristics based on index effectivity value. This soft candy resulted in a water content of 7.46±0.74%, ash content of 0.57±0.07%, and antioxidant activity of 69.20±1.07%. The addition of annatto extract also does not affect the ash content or water content of the goat's milk soft candy produced.

Abstract

Food consumption diversity is an important indicator for assessing the quality of people's diets, especially in the context of urbanization, which affects preferences and access to different types of food. The imbalance of macronutrient consumption, such as the dominance of carbohydrates and low intake of protein and fat, is a public health challenge in Indonesia, including the West Kalimantan region. This study aimed to analyze macronutrient consumption and evaluate the Desirable Dietary Pattern (DDP) score of people in urban areas of West Kalimantan in 2023. This study used a descriptive quantitative approach involving 200 households in Pontianak and Singkawang cities. Data were collected through a food consumption survey and analyzed based on the average consumption of energy, protein, fat, and carbohydrates, as well as the DDP score. The results showed that the average energy and protein consumption in both cities were relatively similar, at approximately 1900 Kcal and 50 Kcal/capita/day, respectively. However, there were significant differences in fat and carbohydrate consumption, with Pontianak recording higher values. The DDP scores were good, at 89.7 in Pontianak and 86.8 in Singkawang. However, there are still inequalities in consumption between food groups, especially the low consumption of oily fruits/seeds, tubers, and nuts. In conclusion, although the energy consumption and food diversity of the community are relatively good, improvements are needed in the distribution of consumption between food groups to support a more balanced and sustainable diet for the community.

Abstract

This study explores the association between household income, fruit and vegetable expenditure, and the intake of selected micronutrients among urban households in Pontianak City. A cross-sectional survey was conducted on 100 households, collecting dietary data on calcium, phosphorus, iron, and vitamins A, B, and C using a 24-hour recall method. Socioeconomic data included monthly income and expenditure on fruits and vegetables. Pearson and Spearman correlation tests assessed the strength and direction of bivariate relationships, while multiple linear regression evaluated the combined effects of income and food expenditure on nutrient intake. Results showed that average household income was Rp 4,382,730, with a mean fruit and vegetable expenditure of Rp 294,880. Vitamin C intake exhibited a very strong and statistically significant correlation with income (Pearson r = 0.998; p < 0.001), and regression analysis confirmed income as a significant predictor (p < 0.001; R² = 0.996). Calcium intake was significantly associated with fruit and vegetable expenditure (p < 0.001; R² = 0.999), indicating that food purchasing behavior may more strongly influence calcium consumption. No significant associations were found between income or expenditure and the intake of vitamin A, vitamin B, iron, or phosphorus. These findings suggest that economic factors selectively influence micronutrient intake, where income plays a critical role in access to vitamin C-rich foods, while expenditure patterns relate more closely to calcium sources. Nutritional interventions in urban areas should consider both economic capability and consumption behavior to effectively address micronutrient deficiencies.

Abstract

Kratom is one of the export commodities from West Kalimantan, containing alkaloids that are beneficial to health. The export product currently in demand is extracted flour. So far, the most widely used extraction method is conventional single extraction, using maceration which is inefficient, long and consumes a lot of solvents. This study examined the process of alkaloid extraction using the technology of drying with a microwave and extraction using a sonicator. The study aimed to determine the microwave drying method which produces kratom leaf alkaloid levels and the type of solvent which produces the strongest IC-50 antioxidant properties from the bath-type sonicator multilevel extraction method. The research method was divided into 2 stages, namely, stage 1 drying with 2 ingredients, kratom leaves with veins and without veins, then tested for alkaloid levels. The leaves material with high alkaloids was continued for phase II of the IC-50 antioxidant property test from various solvents (hexane, methanol, ethanol) using multilevel extraction with a bath-type sonicator. Data analysis was carried out descriptively. The results showed that leaves without veins produced relatively higher levels of alkaloids than leaves with veins. The type of burner that produced IC-50 antioxidant activity was 0.3 ppm ethanol extract. Thus, these results can be a recommendation to stakeholders
