Abstract

Single Cell Protein (SCP) is a biotechnological product designed to enhance biomass or extract proteins and lipids from a given material. One of the methods to utilize single-cell protein is bioencapsulation. Bioencapsulation is a nutrient enrichment technique that involves adding specific substances to natural feed to improve its quality and quantity, thus enhancing its overall nutritional value. The single-cell protein used in this study is Chlorella vulgaris (C. vulgaris), while the bioencapsulation material or observed subject is Artemia salina (A. salina). This study aims to analyze the nutritional content based on the retention or absorption capacity of A. salina using the SCP bioencapsulation method from C. vulgaris and to determine the optimal SCP dosage for bioencapsulation in A. salina. The tested dosages in this study were 100 mg/L, 200 mg/L, 300 mg/L, and 0 mg/L (without SCP administration as a control). The results showed that the SCP retention value in A. salina was significantly different (P<0.05) across the tested dosage treatments. The highest retention value was observed at a dosage of 300 mg/L, with the highest retention of soluble protein and fat recorded at 85.65% and 0.27%, respectively. However, the overall results indicate that as the administered SCP dosage increases, the retention or absorption of SCP nutrients in A. salina also increases.

Abstract

Studies on microdebris contamination in sediments at the estuary of the Pangkajene River were carried out at three stations. This study aims to observe the abundance and characteristics of microdebris in the estuary sediments of the Pangkajene River. The samples of sediment were collected using a core sampler with a diameter of 8 cm. Microdebris was extracted using the flotation method and vacuum filtration system. The particles were observed with a stereomicroscope then classified based on shape (form), size, and color. The number of particles found ranged from 2.83±2.04-4.00±1.87 item/100gr. The analysis of variance (ANOVA) showed p>0.05, therefore the abundance of microdebris between the three stations did not show a significant difference. Microdebris in Fragment form had the highest percentage compared to fibers and granules. Blue and black particles of microdebris were the most common colors. The dominant size of particles was found in the size class <100µm and 100µm-500µm. This preliminary study revealed that the microdebris occurs in the Pangkajene estuary sediments. Currently, we have not classified the types of microdebris found as microplastic, semi-synthetic debris, or natural origin. Therefore, further research is needed to verify particles using an FT-IR Microscope to determine the type of microdebris polymer.
