Abstract

Vitamin A deficiency remains a public health issue, particularly among early childhood populations. Night blindness is one of the early consequences of vitamin A deficiency, which can be prevented through adequate nutritional intake. Parents play a crucial role in shaping their children’s eating habits from an early age. Objective of research is to determine the relationship between parents’ knowledge level and the pattern of vitamin A and daily food intake in the prevention of night blindness in early childhood in Sawah Baru Subdistrict. This study used a quantitative approach with a cross-sectional design. Data were collected through questionnaires and structured interviews with 111 respondents who were parents of children aged 3 to 7 years. Data were analyzed using the Chi-Square test. The majority of respondents had a moderate level of knowledge (57.7%), and their children's patterns of vitamin A and daily food intake were also in the moderate category. Statistical tests showed no significant relationship between parents' knowledge level and vitamin A intake patterns (p=0.133) or daily food intake (p=0.848). Parents' knowledge alone is not sufficient to ensure optimal feeding behavior in the prevention of night blindness. Other factors such as family economy and dietary habits also play a role.

Abstract

Transportation modeling is one of the methods in operations research used to solve transportation problems by considering various variables and constraints. PT. Unichem Candi Indonesia, which has three factories in different locations, faces a transportation problem in the process of delivering salt from its salt-producing regions. This type of research is applied research that employs a quantitative approach. The objective of this research is to determine the minimal transportation cost while taking into account the demand for salt at each factory. The method used to solve this transportation problem is Vogel’s Approximation Method (VAM) to find the optimal solution. The manual data processing using VAM resulted in a cost of Rp. 45,654,851,000. The researchers also used software such as POM-QM, RStudio, and Google Colab (Python) to validate the accuracy of the manual calculations, and it produced the same result of the minimal cost incurred by PT. Unichem Candi Indonesia for transporting salt from the salt source regions to the destination factories, which is Rp. 45,654,851,000.
