The sustainable management of marine ecosystems and fishery resources is a primary goal of the SDGs (Goal 14). Supporting this objective requires the availability of a cold chain network, including ice factories, to preserve the quality and freshness of fish catches. In the southern coastal area of Sukabumi, particularly Ciwaru Village within the Ciletuh National Geopark, the availability of ice factories remains insufficient. Small fishing vessels (<5 GT) in this area require approximately 6 tons of ice per month. This study aims to design the production capacity of a portable mini ice factory to meet the local ice demand. By considering seasonal patterns, fishing volumes, and fluctuating ice needs, the factory is designed to produce around 788–798 tons of ice per year, with an ice storage capacity of 2 tons. The design utilizes 12 kg ice blocks, adjusted to the vessel sizes commonly used by local fishermen employing one-day fishing methods. The planning results indicate that the establishment of this mini ice factory can address the ice supply shortage in Ciwaru, support the maintenance of fish quality, and enhance the economic value of fishermen’s catches.

Fish plays a vital role in early childhood development due to its high nutritional value, yet consumption among preschoolers in Indonesia remains low. This study explores the effectiveness of combining hypnoparenting and storytelling as a complementary nursing strategy to promote fish consumption in young children. A quasi-experimental design with a pretest–posttest control group was used, involving 30 preschoolers divided into experimental and control groups. The experimental group received a four-week intervention integrating hypnoparenting and storytelling, while the control group received standard education. Dietary intake was assessed using a Food Frequency Questionnaire (FFQ). Results showed a significant increase in fish consumption in the experimental group (p = 0.000), with no significant change in the control group (p = 0.102). The Mann-Whitney U test also confirmed a significant difference between the groups (p = 0.000). These findings suggest that integrating hypnoparenting and storytelling is an effective, family-centered complementary nursing approach to promote healthier eating habits. This innovative method offers potential in supporting preschool children’s nutrition and overall development through engaging and parent-involved strategies.
