Abstract

The process of freezing fish always requires a cooler as a temporary storage place for fish. The ability of the storage to maintain cold temperatures is a serious problem to be considered so that the freshness of the fish can be maintained. Therefore, an appropriate technology is required to support the cold chain system so that fish quality can be maintained. The purpose of this study was to test the thermal conductivity of composite materials for fish storage insulation from a mixture of rice husks and polyurethane so that the price of the box can be reduced but still maintain the quality of the fish. The composition of the composite material was made with a volume ratio of 1:0.5, 1:1, 1:1.5, and 1:2. The thermal conductivity test of the material uses the ASTM E1225-99 standard. All test results were compared with 100% polyurethane material. The results of testing the thermal conductivity of 100% polyurethane material obtained 0.023 W/m.C. From all the test results, the material that is most likely to be applied to fish cooler box insulation is a 1:1 composition having a thermal conductivity value of 0.067W/m.C. Materials with this composition do not affect the expansion of the polyol and isocyanate reactions. This composition is the most economical to be used as insulation for fish storage boxes which can save the use of polyurethane by 50%.

Abstract

Patchouli (Pogostemon cablin) cultivated in Pasie Raja District, South Aceh Regency, is widely recognized for its high-quality essential oil and distinctive aroma. However, despite favourable climatic conditions, patchouli production in this region declined substantially in 2023, reaching only 130 tons, which is considerably lower than the national average. This decline is presumed to be partly associated with soil fertility constraints, particularly soil physical properties. This study aimed to analyse the relationship between selected soil physical characteristics and patchouli productivity in Pasie Raja District. The research was conducted at six patchouli cultivation sites, with soil physical analyses performed at the Materials Testing Laboratory of Politeknik Aceh Selatan. Statistical analysis was carried out using Microsoft Excel to examine the relationships between soil porosity, bulk density, effective soil depth, and patchouli yield. The results indicated that bulk density showed a positive correlation with patchouli productivity, explaining 23.23% of yield variation. Soil porosity also exhibited a positive correlation, accounting for 16.68% of yield variation, while effective soil depth had the strongest association, explaining 36.3% of the variation in patchouli yield. These findings suggest that soil physical characteristics play an important role in patchouli production and may serve as a scientific basis for improving soil management practices to enhance patchouli productivity.
