Abstract

One of the toxic anions such as cyanide (CN-) has a negative impact on living things. Pyrazoline derivatives can be complexed with transition metals and used as CN- ion fluorosensor, because pyrazoline derivatives have fluorescence properties. This study aims to synthesize of CN- ion chemosensors based on pyrazoline derivative namely para-di-2-(1-phenyl-3-pyridyl-4,5-dihydro-1H-pyrazole-5-yl)benzene with Cu metal. The resulting complex compounds were characterized using Spectrophotometer Infra Red (FTIR), Spectrophotometer UV-Visible, and Spectrofluorometer. Then, a complex compound chemosensor (fluorosensor) study of Cu2+ was carried out with the addition of CN- ions using a spectrofluorometer. The results showed that the synthesis of complex compound Cu2+ was successfully carried out and a brown precipitate was obtained with a yield of 43% with a melting point of 243.3°C. Based on the results of characterization by FTIR (cm-1) generates 3400 (Amine), 2920.88-2852.42 (C-H pyridine), 2360.38 (C=N), 1594.50-1490.39 (C=C aromatic), 1233.67-1021.17 (C-N),  982.66 (Cu-O), 348.00 (Cu-N), and 320-280 (Cu-Cl). The results of the spectroscopy UV-Visible analysis Cu2+ complex compounds at a concentration of 5x10-5 M obtained two absorption peaks, 242 nm and 306 nm. The result of the spectrofluorometer analysis of Cu2+ complex compound were 1516 a.u at a wavelength of 502 nm. The results of the chemosensor (fluorosensor) studies of the Cu2+ complex compound with the addition of CN- ions can be used as a turn on-off  type fluorosensor.

Abstract

Invasive Plant is species that dominate an area or places, both are native species and non-native species. Invasive Plants is one of the crucial problems in ecosystem management because it is a major component of global environmental change, threats to biodiversity and local species, as well as, causes of changes in nutrient cycles, fire cycles, hydrological cycles, and energy balance. The purpose of this study is to prove that plants far from the road are more commonly invaded by invasive species and that physical and biological factors affect the growth of invasive species. The research was conducted at the Dramaga Research Forest, Bogor from June 2020 to August 2020. This study used a vegetation analysis method, which is using nesting plots that have a size of 2 x 2 m for seedlings, 5 x 5 m for saplings, 10 x 10 m for poles, and 20 x 20 m for trees. Plots were made in two locations, close to the road and far from the road. The location close to the road was 5 - 10 meters, and far from the road was 70 - 80 meters The total plots made in this study were 16 plots in each size. The results showed that the highest diversity was found at the level of seedlings, namely medium status (2.00-3.00) according to the Shannon-Wiener index. The results showed that the statistical analysis of the diversity of weeds in the Dramaga Research Forest were not significantly different, between plants close to the road and plants far from the road. This is causing by physical factors that are not significantly different based on statistical tests. The growth of invasive plant species is influenced by several factors, such as light intensity, temperature, humidity, and soil pH. Keywords: Dramaga Research Forest Bogor, Invasive species, Vegetation analysis

Abstract

Longan plants (Dimocarpus logan L.) are generally used by the community only for their fruit. Longan leaves contain secondary metabolites such as flavonoids, polyphenols, saponins, and tannins. Flavonoids are polyphenolic compounds and have antioxidant properties that are not heat-resistant, therefore a suitable method is needed for extracting flavonoids, especially methods that do not use heat. Maceration extraction method is an extraction method by immersing simplicia at room temperature, while the Microwave Assisted Extraction (MAE) extraction method is an extraction method using microwave radiation. The study aims to determine the most effective method for flavonoid content of longan leaves using 2 extraction methods, namely maceration and MAE. Determination of flavonoid content was done using Aluminium chloride reagent whose absoption was measured using UV-Vis spectrophotometry. The results showed that the best extraction method to produce the highest flavonoid content in 70% ethanol extract of longan leaves was the Microwace Assisted Extraction method which produced flavonoid levels of 1.32 ± 0,09%.

Abstract

In the cultivation of tilapia (Oreochromis niloticus), there are still some obstacles or obstacles that farmers complain about, one of which is the high price of commercial feed, because one of the most important factors in cultivation is quality feed. Fish growth will increase if the feed given can be digested properly by fish so that the energy obtained by fish from feed can be utilized optimally. Therefore, with the background of some of the problems above, it is necessary to add natural feed in tilapia cultivation, with a nutritional composition that is in accordance with the needs of fish, this study was conducted with the aim of knowing the effect of adding natural feed in the form of turmeric extract as an immunostimulant that can trigger the growth of tilapia, as well as to determine the effect of differences in the concentration of turmeric extract added to each tilapia feed on the growth rate (weight and body length) of tilapia. This research was conducted through an experimental method, where the treatment given was in the form of adding turmeric extract with different concentrations to the artificial feed of tilapia. The results of this study proved that the higher the dose of turmeric extract added to the feed, the higher the growth rate of body length and weight of the tilapia. This is due to the balance of protein, and has the main content in the rhizome, namely essential oils and curcumin which can increase appetite, and also acts as an antioxidant.
