This research aims to utilize isolated chitin from shrimp waste to develop histamine biosensors basedon diamine oxidase (DAO) enzyme electrode with cyclic voltammetry. DAO enzyme trapped in the chitin-cellulose acetate membranes with various comparisons were layered on the Pt electrode. Histamine will be oxidized by the DAO enzyme produces aldehydes and H2O2 which acts as an electron transfer mediator. Biosensor performance is influenced by several factors, especially the concentration and composition of electrode membranei.Comparison of chitin-cellulose acetate used in this study were 1:1, 2:1 and 3:1. Isolated chitin from the shrimp waste is chemically obtainedrendamen of 23.6%, and characterization of electrode membrane by FTIR and cyclic voltammetry showed that the DAO enzymes electrode with chitin-cellulose acetate membrane 2:1 is the best composition.

Optimation studies have been conducted using hydrogen peroxide (H2O2) to the reduction of cyanide levels in the wastewater. Parameters studied were the optimum concentration of hydrogen peroxide (H2O2), the optimum pH and optimum contact time between hydrogen peroxide (H2O2) with wastewater in reducing the cyanide content. Cyanide obtained from steam distillation of liquid waste and the assay using 0.02N silver nitrate. Concentration used were 500 ppm, 400 ppm, 300 ppm, 200 ppm and 100 ppm; pH range is (7, 8, 9, 10 and 11) and the variation of the contact time is: 0, 30, 60, 90, 120 and 150 minutes. The result of the research reveals at early treatment the cyanide content is 50,22% w / w and underwend a reduction in levels after addition of various concentrations of H2O2; variations in pH variation of contact time. Optimum condition treatment at 500 ppm of H2O2 basicity at pH 8 and contact time for 60 minutes result reduction of cyanide level of 36,40% w/w, 40,91% w/w and 37,09% w/w respectively.

Estrogen-α (ER-α) is a major target in cancer therapy. Targeting the ER-α target protein is known to slow the proliferation of breast cancer cells. The purpose of this study was to determine the interaction of the complex compound Zn(II)Prolinedithiocarbamate against the Estrogen-α Receptor. The Zn(II)Prolinedithiocarbamate complex was predicted canonical SMILE by Cheminfo online application (O=C(O)C1CCCN1C2S[Zn]S2) and modeled with online corina to obtain a three-dimensional structure. The structure of the complex compound Zn(II)Prolinedithiocarbamate interacted with Estrogen receptor alpha protein to test its potential anticancer activity. Molecular docking results show the interaction of the Zn(II)Prolinedithiocarbamate complex with the Estrogen- receptor on the amino acid residues ARG394, LEU387, GLU353, LEU346, LEU349, and PHE404. The Zn(II)Prolinedithiocarbamate complex interacts directly with ER-α in the estrogen region which causes the failure of the interaction between estrogen and the estrogen receptor, so it can be predicted that the Zn complex has activity as an ER-α inhibitor and has the potential to be developed in the treatment of breast cancer.

An investigation on the effect of Mg2+ on its lipid content from phytoplankton Chlorella vulgaris as a raw material for producing biodiesel by ultrasonic method has been carried out. The results showed that Mg2+ is good as a nutrient for phytoplankton. The optimum concentration was 0.4 ppm. Total of dry biomass was 32.7902 grams. Lipid was extracted by ultrasonic method using ethanol 95% as solvent. Biodiesels were syntesized in two steps namely esterification by methanol solvent and H2SO4 as catalyst, folowed by transesterification by using methanol solvent with KOH as a catalyst. Total of biodiesel made was 11.5727 grams and the yield was 35.29%. The result of biodiesel characterised in term of physical and chemical characteristics including: density, viscosity, free fatty acid, saponification value, and iodine value, respectively. Result of the analysis showed that biodiesel characteristics have fulfilled standard the American Society for Testing and Materials (ASTM D6751), except value of density and Free Fatty Acid.

The research aimed to find out the effect of Fe2+ and Mn2+ towards β-carotene productivity as result of oxidative stress from photosystem (PS II). The phytoplanton Isocrysis aff galbana (T-iso) were the microalgae species which had the high lipid content primarily and had potentiality to produce β-carotene as the β-carotene supplement. Analysis method was carried out by the sonication extraction for short and cheap in the lysis cell of phytoplankton biomassa, infra red (IR) to find out the interaction metal ion and UV/VIS spectrophotometer to determine β-carotene concentration. The research result indicateds that Fe2+ has higher impact than Mn2+ on the β-carotene productivity. The interaction of ions metal indicates as M-N, -O-M and M←OH-C complex in the phytoplankton amino acid. The β-carotene concentration is 4,97 µg/g DW in addition Fe2+ 0,30 ppm and 1,95 μg/g DW in Mn2+ 0,20 ppm. The dry weight concentrations of β-carotene indicates that I. aff galbana with Fe2+ addition has potential as β-carotene supplement.

Cadmium is an element that can accumulated in seaweed thallus. One of an alternative methode was used to determine the amount of Cd(II) ions were accumulated in Euchema Cottoni thallus is adsorption methode, that was conducted with variations of contact time and concentrations. The concentrations of Cd(II) ions in solutions were determined by using Atomic Absorption Spectrophotometer (AAS). Isothermal model to evaluated the maximum adsoprtions capacity were used Freundlich and Langmuir isotherms. Based on both isothermal models the results showed that adsorption capacity were 33,898 mg/g wet weight by Langmuir and 0,00625 mg/g wet weight by Freunlich isotherms respectively. The adsorptions energy (ΔG) is 9,7482 KJ/mol indicated as physisorptions. While infrared spectrum showed Euchema cottoni have –OH, CO2, -CH2, -CH3, and - SO3- functional groups.
