Dimsum is a popular snack made from chicken wrapped in wheat flour dough and cooked by steaming. It is favored by many due to its delicious taste and affordable price. However, dimsum sold by street vendors often lacks proper hygiene during processing and presentation, making it prone to microbial contamination. Chicken, as the main ingredient, is high in protein, which supports microbial growth. Contamination of microorganisms in food poses health risks to consumers. This study aims to analyze Total Plate Count (ALT) and Salmonella contamination and examine the correlation between chemical characteristics, such as water content and pH, and microbiological growth in chicken dimsum sold by five vendors in Way Halim District, Bandar Lampung City. The microbiological and chemical data were analyzed descriptively, and Pearson Correlation was used to determine the relationship between chemical characteristics and microbial growth. The results showed that all chicken dimsum samples exceeded the maximum ALT limit, and two samples tested positive for Salmonella. Referring to SNI 7756:2013, the standard for siomay quality and safety is a maximum ALT of $5 \times 1 0^{4}$ CFU/g and negative/25 g for Salmonella. The correlation test indicated that water content and pH had a significant relationship with ALT growth. The chicken dimsum sample with the highest ALT was the DC sample (6.31 log CFU/g), while the lowest was the DA sample (5.35 log CFU/g). Salmonella contamination was found in the DC and DE samples.

Tea contains chemical compounds that are beneficial to the body, such as phenolic compounds. Packaged tea drinks are obtained from steeping tea with the addition of water, sugar, synthetic flavors, stabilizers, acidity regulators, and food additives that are tightly packaged. This research aims to evaluate the suitability of the quality of packaged tea drinks based on SNI requirements and determine physicochemical characteristics which include pH and total dissolved solids, while functional properties include total phenols and antioxidant activity. This research used a purposive sampling technique designed with a Completely Randomized Design with two duplicate replications. The results of the physicochemical and functional characteristic tests were analyzed using the ANOVA method and DMRT with α=5%. The results show that ready-to-drink tea products have a pH value between 5.4–6.79, total dissolved solids with a value of 6.5–8.2 °Brix, and antioxidant activity with a value of 56.83%–79.15%, where in terms of physicochemical content and functional properties, the five samples of packaged tea drinks can be said to be good. However, only 3 of the 5 samples had phenol content that was in accordance with that required by SNI 3413 of 2011.

Reinforcing Local Food Security through Agrogeological Perspectives: South Lampung, Indonesia

2025-04-29T03:29:19+00:00

Local food security is a critical priority for the coming decades, especially in Indonesia. As the population grows, it is essential to meet local food needs before participating in the national supply. South Lampung, a key region in Sumatra, plays a vital role in the nation’s food supply. However, rapid population growth in this area has raised concerns about the conversion of agricultural land to residential use. To address these challenges, this study raises agrogeology as an alternative approach to reinforcing local food security. By re-evaluating the regional geological characteristics, the study aims to understand the distribution of productive, traditional paddy fields. Field surveys and spatial analyses were conducted for this study. The findings reveal that the silicate-rich lithology in the region’s pyroclastic deposits significantly contributes to maintaining fertile soils, particularly in areas such as Candipuro, Jatiagung, and Palas. Natural drainage systems further support rice cultivation. In alignment with the Sustainable Development Goals, the agrogeological perspective emphasizes the need to mitigate land conversion and improve land-use planning. This approach offers a sustainable pathway to enhance paddy field productivity and ensure water and nutrient availability, thereby supporting long-term local food security.

The Effect of Sorghum Juice Concentration (Sorghum bicolor L.) on Yogurt Characteristics

Yogurt is a derivative product of milk that undergoes a fermentation process aided by bacteria during production. Various types of bacteria, such as Lactobacillus bulgaricus and Streptococcus thermophilus, are utilized in the fermentation process. Sorghum holds numerous health benefits, including contributing to the prevention of heart disease, obesity, hypertension, maintaining blood sugar levels, and preventing colorectal cancer. Additionally, sorghum contains resistant starch and oligosaccharides that are resistant to digestion by the human body, making it suitable for use in synbiotic beverages. The research aimed to analyzed the influence of different concentrations of sorghum extract on the characteristics of yogurt, including chemistry and microbiology aspects. The results of the ANOVA tests for each parameter were found to be statistically significant and markedly different. Titration of total acidity, total dissolved solids, viscosity, and total lactic acid bacteria increased with the addition of sorghum extract.

Analysis of Vitamin A Content and Antioxidant Test in Super and Bulk Olein

Cooking oil is the essential food for bodies. Cooking oil should be enriched with vitamin A because this substance plays a critical role in maintaining health. Cooking oil contains antioxidant compounds, which inhibit or slow down oxidation reactions. This study aimed to determine the amount of vitamin A in super olein and bulk olein before fortification and the amount of antioxidant content in super olein and bulk olein before fortification. The amount of vitamin A content was obtained using the High-Performance Liquid Chromatography (HPLC) method of <0.005 IU/gram, while the antioxidant test results were carried out by the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) method using UltraViolet-Visible Spectrophotometry (UV-Vis). The resulting antioxidant activity has an inhibition value of 23% and 10% in bulk and super olein, respectively. Cooking oil is the essential food for bodies.
