Abstract

Zeolite, as an adsorbent, can be improved by a chemical activation process. In this study, zeolite was activated using the acid activation method by soaking natural zeolite with HCl and HF, and the activated zeolite was then used to adsorb Fe metal. Zeolite was characterized using SEM and XRD, and the adsorption capacity of the zeolite was analyzed using AAS. The results of SEM analysis show that zeolite after activation has a more significant number of pores than zeolite before activation. The results of XRD analysis show that zeolite that has been activated has a higher content of quartz (SiO2) and clinoptilolite than zeolite that has not been activated. The results of the zeolite adsorption capacity and efficiency test on Fe metal showed that the most excellent adsorption capacity was when the contact time was 60 minutes, with adsorption capacity and adsorption efficiency values of 3.2403 mg/g and 97.21%.

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.

Abstract

Dodol, which belongs to the category of semi-moist foods (foods with intermediate moisture), is immediately consumed due to its sugary, chewy appearance. Seaweed will acquire economic value subsequent to undergoing additional processing, such as the transformation into seaweed dodol. The objective of this study is to differentiate the nutritional and hedonic benefits of Sicini dodol in response to fortification with Eucheuma cottonii seaweed. GOWATE REGION-PERI. This research methodology employs three interventions and three repetitions in an experimental laboratory. Analysis of data employs the Anova test. The water contents of samples A (27.81%), B (35.86%), and C (36.86%) were displayed in the results. Ashes A (1.04%), B (1.40%), and C (1.64%) by weight. The protein concentrations are as follows: A (3.44%), B (3.48%), and C (3.58%). Samples A (7.27%), B (9.26%), and C (8.86%) contained fat, respectively. Carbohydrates A (56.60%), B (61.69%), and C (66.02%) are examples. Samples A (1.61%), B (3.73%), and C (6.32%) comprise crude fiber. The hedonic test outcomes indicate that samples A (7.50), B (6.80), and C (6.20) have an average appearance. As indicated by the average fragrance of samples A (7.27), B (6.70), and C (5.40). Based on the typical taste, samples A (7.50), B (7.10), and C (5.70) are evident. As shown by the average textures of samples A (7.00), B (6.40), and C (5.60). In conclusion, seaweed lunkhead Eucheuma cottonii affects chemical and hedonic quality. Keywords: Dodol, Eucheuma cottonii seaweed, chemical tests, hedonic
