Abstract

Research about composition of superior nutrients, growth parameters, and best method to maximize production of biomass sea phytoplankton, Chlorella  vulgaris, Dunaliella salina, and Spirulina sp. has been performed. The nutrients was named as MSSIP which were consist of following compositions: urea fertilizer, Arschat-M nutrient, Fe:Co:Ni metal ions (6 : 3 : 9 : 6 : 3). Methods used were identification and analysis of sea phytoplankton.  Determination of optimum growth condition, pure culture, and mass culture were using local raw materials-based engineered nutrients or MSSIP (M. Sjahrul-Syahruddin Kasim-Indah Raya-Paulina Taba). Determination of product density of sea phytoplankton biomass, analyses of carbohydrate content, and lipid biomass were done by using haemocytometer and microscope, Luff Schrol method, and soxhlet method (n-hexane as solvent), respectively. Morphology of phytoplankton was identified by using a digital camera microscope, SZ60/sZ60-61. Furthermore, to understand the effect of metal ions, Fe, Co, and Ni added into MSSIP nutrient, identification of nutrient before and after culturing process were done using XRF-Thermo-Fisher.  The results showed that Chlorella  vulgaris, Dunaliella salina, and Spirulina sp. were suitable as raw materials  to produce biofuel. Those three phytoplankton contained 0,3095 g/L, 0,3782 g/L, and 0,3325 g/L biomass, 32,49%w/w, 31,58%w/w, and 29,81%w/w carbohydrates; and  25,95%w/w, 26,82%w/w and 24,53%w/w lipid, respectively. Best optimum condition of culture were salinity of 30-35%, temperature of 20-30 °C, pH of 8-9, initial density of 2.5 x 104 cell/mL, light exposure of 40 watt, and continuously aerated with CO2. Based on our study, sea phytoplankton, Chlorella  vulgaris, Dunaliella salina, and Spirulina sp. have a high potency as source of bioethanol and biodiesel.Keywords: mass culture, superior nutrient MSSIP, sea phytoplankton biomass, Fe, Co, Ni metal ions

Abstract

Robusta coffee (Coffea canephora) is the most widely produced coffee in Indonesia. The relatively high acid content causes robusta coffee to be less attractive to both local and international consumers. Acid levels in coffee can be reduced by heating techniques using water as a solvent because it is cheap and easy to obtain and water is also a safe solvent and has no side effects for health. Coffee bean water content was analyzed by heating to constant weight by the oven method, acid content by titration technique, and followed by organoleptic testing. The results of the analysis of water content for dry treatment of 10.02%, wet treatment of 10.35% and on heating for 15, 30, 45, 60, 75, and 90 minutes respectively at 9.99%; 10.34%; 9.70%; 10.40%; 11.65% and 11.36%. The results of the analysis of acid levels for the treatment of dry processing amounted to 3.65%, wet processing amounted to 3.42%, and for heating for 15, 30, 45, 60, 75, and 90 minutes respectively 3.03%; 2.76%; 2.51%; 2.39%; 2,32% and 2,28%. Organoleptic test results showed that the decline in the quality of coffee occurs when heating above 45 minutes. Based on research data it was concluded that the heating method can reduce acid levels in coffee beans with a maximum heating time of 45 minutes to maintain the quality of taste in coffee. Keywords: Coffea canephora, organoleptic, warming up, titration.

Abstract

Nanoparticles was done by adding water hyacinth leave extract to AgNO3 2mM solution with a ratio of 1:40. Formed silver nanoparticles were analyzed using UV-Vis spectrophotometer, SEM, XRD, PSA, and FTIR to determine its characteristics. Results showed that absorbance value increased if reaction time is increased. Maximum absorption was obtained at wavelength 432-446 nm by using UV-Vis spectrophotometer. Result of PSA analysis shows that the average size of silver nanoparticles formed is 93.2 nm while XRD analysis shows that the average crystal size of silver nanoparticles is 50.11 nm, with round shape and amorphous. Result of FTIR analysis to determine functional group that contributes to nanoparticle synthesis shows the contribution of OH group.

Abstract

Silver nanoparticles have been synthesized by the reduction method using salam leaf extract (Syzygium polyanthum) as a reducing agent. The silver nanoparticles produced were then tested for their activity as antioxidants. The formation of silver nanoparticles was carried out by adding the leaf extract into the solution of AgNO3 and homogenized using a magnetic stirrer. A UV-Vis spectrophotometer was used to confirm the formation of silver nanoparticles. Particle Size Analyzer (PSA), Scanning Electron Microscope (SEM), X-Ray Diffractometer (XRD) and Fourir Transform Infra Red (FTIR) spectrometers were used to characterize the nanoparticles produced before being tested for antioxidant activity. The results showed that the absorbance value increased with increasing reaction contact time. The maximum uptake was obtained at wavelengths of 432-446 nm using a UV-Vis spectrophotometer. The particle size was determined using a PSA with an average particle size distribution of 45.7 nm. The average diameter of silver nanoparticles was 10.06 – 13.97 nm and the silver nanoparticles had rod-shapes. Functional groups that play a role in the synthesis of nanoparticles were –OH, –C=O, and –C-O groups. Silver nanoparticles inhibited free radicals as antioxidants with the IC50 value of 582.7 ppm.

Abstract

The mining industry in Indonesia is growing rapidly, giving an environmental impact from the waste produced because it contains dangerous heavy metals, one of which is cadmium metal (Cd). The purpose to know the ability of cadmium resistance in bacterial isolates. Bacterial isolates were obtained from soil samples from the Poboya Gold Mine field, Palu. Bacterial isolation and selection were carried out by the plate count method, resistance testing using nutrient broth media containing heavy metals Cd, analysis of Cd concentrations using atomic absorption spectrophotometers. From the results of the study, four types of Cd resistant isolates were obtained based on macroscopic and microscopic characterization results, namely isolates EK1, EK2, EK3 and EK4. The two best isolates of Cd resistance, EK2 and EK4 isolates were tested on media containing 20 ppm Cd, showing that both of these isolates were able to significantly reduce Cd concentrations in the supernatant and pellets.
