Abstract

The first thousand days of life are a golden period that greatly determines the optimal growth and development of children. Exclusive breastfeeding plays an important role in meeting the nutritional needs of infants and reducing morbidity and mortality rates in children. However, the coverage of exclusive breastfeeding has not yet reached the expected target. Various factors, including the level of knowledge and attitude of mothers, are thought to influence the success of exclusive breastfeeding. This study aims to analyze the factors that influence exclusive breastfeeding in infants over 6 months of age in the Pattingaloang Health Center work area, South Sulawesi. This study used a correlation analytic design with a cross-sectional approach. The sample in this study were 33 mothers who had infants aged 6–24 months and were selected using the total sampling technique. Data were obtained through questionnaires and analyzed using the Chi-square test with the help of SPSS. The results of the analysis showed that there was a significant relationship between the level of maternal knowledge and exclusive breastfeeding (p-value = 0.028). Mothers with good knowledge are more likely to provide exclusive breastfeeding than mothers with poor knowledge. Meanwhile, no significant relationship was found between the mother's attitude towards breastfeeding and exclusive breastfeeding (p-value = 0.532). In addition, age, education level, and occupation also contribute to the formation of maternal knowledge about exclusive breastfeeding. The level of maternal knowledge significantly influences the success of exclusive breastfeeding, while maternal attitudes do not show a significant relationship. Therefore, efforts are needed to increase education and counseling regarding the importance of exclusive breastfeeding, especially for mothers with low education levels or limited access to health information

Abstract

This study aimed to isolate and evaluate the biological safety and potential of endophytic bacteria from Sauropus androgynus (katuk) and their Chitinolytic activity for use as biological agents. A total of 14 endophytic bacterial isolates were obtained from different plant parts: 5 from the roots (T1, T2, T3, T4, P14), 5 from the stems (T7, T8, T9, T10, T11), and 4 from the leaves (T5, P6, KB12, T13). The safety of these isolates was assessed through hypersensitivity (HR) and hemolysis (HL) tests. In the HR test, none of the isolates induced necrotic symptoms in tobacco leaves, indicating they are not pathogenic to plants. In the HL test, two bacterial which were T4 from roots and T5 from leaves, isolates were found to produce clear zones on blood agar, indicating α-hemolysin production. However, the other isolates did not form hemolysis zones, suggesting they are safe for mammals. Antibacterial activity against the plant pathogen Ralstonia solanacearum was evaluated using spot inoculation methods. The results showed that none of the isolates were able to inhibit the growth of R. solanacearum. Further testing revealed that one bacterial isolate which was T8 obtained from the stem produced chitinase, as evidenced by the formation of a clear zone around the bacterial colony on chitin-containing media.

Abstract

Trash fish, often regarded as low-value bycatch, actually holds significant potential as a source of protein and essential minerals such as calcium and phosphorus. This study aims to evaluate the effect of different drying methods—oven drying at varying temperatures (40°C, 60°C, 80°C, and 100°C) and sun drying on the protein, calcium, and phosphorus content of trash fish. Laboratory analyses were conducted using the Kjeldahl method for protein determination and atomic absorption spectrophotometry (AAS) for calcium and phosphorus content. The results revealed that increasing oven drying temperatures significantly reduced protein levels, while sun drying maintained a protein content close to the optimal range. In contrast, calcium and phosphorus levels showed no significant differences across drying methods. Therefore, low-temperature oven drying or sun drying is recommended to preserve the nutritional quality of trash fish effectively.
