Abstract

This research is an experimental research which aims to determine the effect of synthetic fertilizers urea, TSP and ZA on the amount of biomass and chlorophyll content of Dunaliella sp. on a laboratory scale. The research design used was a completely randomized design (CRD) consisting of 5 treatments with 3 replications each to obtain 15 treatment combinations. The research method consisted of several stages, namely preparation of tools and materials consisting of making culture media, making walne medium and making treatment medium, sterilizing tools and medium, preparing Dunaliella sp inoculum. on Walne medium with a static system, as well as optimizing the growth of Dunaliella sp.. The parameters observed in this study were phytoplankton biomass (dry weight), total chlorophyll content, salinity, pH, temperature, and light intensity. Based on the research results, the highest average biomass was found in the P3 treatment, namely the Walne medium treatment with the addition of 105 ppm urea, 80 ppm TSP, and 80 ppm ZA which produced an average of 5.23 g/L. Furthermore, the highest average results for measuring chlorophyll content were found in treatment P4 with walne medium treatment which added 115 ppm urea, 75 ppm TSP and 75 ppm ZA which produced an average of 1.81 µg/mL. So it can be concluded that the synthetic fertilizers urea, TSP and ZA have an effect on the amount of biomass and chlorophyll content on the growth of Dunaliella sp.

Abstract

Pectin is an essential polysaccharide that is usually found in the skin of various fruits and vegetables. It acts as a gelling agent and stabilizer in many food and pharmaceutical industries. This study focuses on the potential of grapefruit peel as a source of pectin. Pectin is isolated from hot grapefruit peel powder (albedo). The aim of this study was to extract pectin from grapefruit peel (albedo), and central composite design (CCD) together with the numerical optimization method of response surface methodology (RSM) was used to optimize the processing parameters, including temperature (60, 80 and 100 ° C), pH (1.5, 2.0 and 2.5 ) and time (60, 90 and 120 min) The findings show that the studied parameters have a major impact on the pectin yield. The resulting second-order polynomial model thoroughly explains the relationship between input and output variables and how the data is varied. The highest pectin yield was 28.45% at optimal conditions achieved: temperature: 100° C; pH: 1.5; and extraction time: 120 minutes. Temperature, pH, and extraction time have their own large impact on pectin yield which has a significant effect.
