Abstract

This study aims to determine the frozen shelf life of Lawa’ Mairo by analyzing the total plate number. This research was carried out in June 2022, the manufacture and testing of Lawa 'Mairo was carried out at the Laboratory of the Fishery Product Quality Application Center, Makassar, South Sulawesi. This research is classified as quantitative research with experimental method, with four treatments (storage time). Three lengths of frozen storage, namely 1 day, 3 days, and 5 days, as well as 0 days as control (fresh lawa' mairo). Data analysis used the t test to see the effect of storage time on microbial growth and the effect of sensory values on treatment. The results of this study indicate that the shelf life of frozen lawa' mairo from ALT testing that has been carried out is classified as safe for consumption. Lawa’ mairo can last as long as in cold or frozen conditions. Based on the t test, the storage time was declared to have a significant effect on microbial growth in frozen lawa' mairo products. The results of the sensory test on the hedonic scale showed that the panelists' preference level was highest on fresh lawa' mairo (0 days storage). Based on the panelists' assessment of frozen lawa' mairo, there was a change in taste due to an oxidation process during the storage period. Based on the t test performed, it is stated that it has a significant effect between the sensory values of the hedonic scale on the storage time (p<0.05).

Abstract

Calcium is a mineral that can be found in the shells of sea urchins. Calcium supplementation in pill form is commonly encountered within the community, derived from both animal and vegetable sources. The objective of this study is to investigate the physico-chemical properties of calcium derived from the shells of the sea urchin species Diadema setosum. The research was conducted between April 2023 and June 2023, involving sample collection on BarrangLompo Island and subsequent testing at the Chemical Laboratory of Pangkep State Agricultural Polytechnic. The study methodology employed entailed conducting experiments within a controlled laboratory setting where distinct treatment media were utilized. Specifically, the treatments employed were denoted as Treatment A, characterized by a temperature of 1000 °C, and Treatment B, characterized by a temperature of 500 °C.The findings of the study conducted on calcium derived from sea urchin shells (Diadema setosum) revealed that the calcium exhibited two distinct colors, namely dark brown and light brown. Additionally, some samples possessed an odor, while others were odorless. Furthermore, the texture of the calcium was observed to be smooth. The average yield values for treatment A and treatment B were determined to be 1.49 and 1.80, respectively. Moreover, the average water content values for treatment A and treatment B were found to be 1.29 and 1.06, respectively. Lastly, the average calcium content values for treatment A and treatment B were measured to be 83.30 and 78.20, respectively. Based on the results of statistical analysis, it is evident that there is no statistically significant disparity observed in the yield, water content, or calcium content of sea urchin shell calcium flour (Diadema setosum).

Abstract

Caulerpa racemosa is a type of seaweed that has the potential to be cultivated because it is known and favored by the public.Caulerpa racemosa is used not only for consumption as food but also for beauty cosmetics because of its ingredients. This study aims to determine the Bioactive content and total plate count (TPC) of the Caulerpa racemosa peel-off gel mask. The pour plate method was used to determine the total plate number of mycobacteria and phytochemical testing in the form of tests for flavonoid, alkaloid, phenolic, tannin, triterpenoids, and saponin. The results showed that the total colony total plate count until the 3rd repetition had an average of 31 col/g. The results of the phytochemical test of the Caulerpa racemosa peel-off gel mask contained bioactive compounds: flavonoid, alkaloid, phenolic, tannins, triterpenoid, and saponin. Conclusion: The Total plate count of Caulerpa racemosa peel off the gel mask complies with Indonesian National standards (INS) with the content of bioactive compounds, namely tannins dan saponins. Caulerpa racemose was used for a pell-off gel mask for the first time.
