The process of increasing vitamin E concentrate in candlenut oil aims to obtain higher vitamin E levels from candlenut oil through a major and minor component separation with adsorption and desorption methods with three types of calcium silicate hydrate adsorbent namely calcium silicate with 90% absolute ethanol (Ca-S 90), calcium silicate with 75% absolute ethanol (Ca-S 75) and calcium silicate synthesized from CaO (Ca-S). The three adsorbents were synthesized by hydrothermal method at 170ºC for 24 hours accompanied by stirring and characterized by XRD, SEM-EDX, and BET. Furthermore, the adsorbent was applied to enrich vitamin E concentrate in candlenut oil through the adsorption process using a glass column with a mass ratio between candlenut oil and adsorbent that was 1:1, then the vitamin E desorption process was carried out by adding n-hexane solvent. Vitamin E levels obtained after the adsorption and desorption process were for Ca-S 75 adsorbent was 764.41 ppm (1. 82 times enriched), for Ca-S 90 adsorbent was 1011.29 ppm (2. 40 times enriched) and for Ca-S adsorbent was 1029, 38 ppm (2.4 5 times enriched) from the initial vitamin E level in candle nut oil was 420.66 ppm.

Cultivate koi fish in the aquarium with water from the Tuntungan river had various pHs between 5 to 10. NaH2PO4 is used to reduce pH level, while NaHCO3 is used to elevate pH level.  Before the fish was placed, the mineral content of Fe, Mg, Ca, and Cl in the water after pH arrangement was analyzed. The initial weight of the fish that will be incorporated into each aquarium was weighed. After ten days, the fish were weighed, and the mineral content of Ca, Mg, and Cl were determined by titration method, whereas Fe mineral was determined using the Visible Spectrophotometry method.
