One of the raw water sources in Indonesia is well water. However, the water mostly smells, turbit, and dirty. Dumai Timur is one of the subdistricts in the Dumai municipality that have bad quality water. People use well water for daily activities but the water is the smell and the color is yellowish and leaves rust stain in functional partitions. This rust stain estimated as iron ion (Fe2+ and Fe3+). Iron ion needed in red blood cell formation; however, if it exceeds the defined level, this ions is harmful. This research aimed to identify the iron ions level in well water used by people at Kecamatan Dumai Timur. Samples obtained from some well water in Dumai Timur that consist of five Kelurahan. Technique sampling was random sampling and the iron ion was detected in a laboratory using SNI 6989.4:2009. The result compared with the defined level by the Minister for Public Health No. 416/1990.

Catfish bones have been successfully synthesized into hydroxyapatite through the precipitation method. Catfish bone used because it will produce hydroxyapatite that is more biocompatible with bone. The model used is a laboratory experiment through the method of precipitation which synthesizes the bones of catfish that have been calcined with nitric acid, aquades, ammonium hydroxide, and diammonium hydrogen phosphate to produce hydroxyapatite products. The FTIR results show that there are hydroxyapatite constituent groups at their peak. XRD shows that the product produced is indeed hydroxyapatite because it complies with the standards of the ICCS. The results of SEM showed there is an agglomeration of the product produced due to the precipitation method itself.

Staphylococcus aureus (S. aureus) is a pathogenic microbe that is caused by various diseases in humans and animals. Infectious diseases caused by S. aureus in Asia reached 70% in 2007, while in Indonesia reached 23.5%. The plant provided several bioactive compounds that might function as an antibacterial which inhibits both bacterial growth and damaging the cell system and protein synthesis. Coleus arthropurpureus known contains alkaloids and tannins that supposed to be an antibacterial compound. Tannins have antibacterial activity, in general, the mechanism is to damage the bacterial cell membrane and induce the formation of complex compound bonds to enzymes or microbial substrates. This study aims to analyze the bioactive compounds contained in C. arthropurpureus in qualitative and quantitative which have an antimicrobial function using high-performance liquid chromatography (HPLC) in the reverse phase C-18 column and screening of antibacterial activity was carried out by disc diffusion method. The results of both qualitative and quantitative analysis by HPLC has obtained the presence of tannin bioactive compounds (1.48 ppm at a retention time of 2.806 minutes) and alkaloids (1.11 ppm at a retention time of 7.015). Moreover, we verified the diameter of inhibition of growth zone against S. aureus at a concentration of 15% extract was 12.80 mm. It was found that the highest percentage of the bioactive compound in C. arthropurpureus is tannin, and that is might an antibacterial agent.

VEGFR2 (Vascular Endothelial Growth Factor Receptor 2) plays a key role on tumor angiogenesis. Inhibition of VEGFR2 mediated-biological signaling pathways by chemical compounds has been considered as an effective therapeutic option for cancer treatment. This study aims to identify new candidates of VEGFR2 inhibitor compounds using the method of computational molecular modeling (in silico) namely pharmacophore analysis, virtual screening and docking. From the results it is identified that N-(1-chloro-9,10-dioxoanthracen-2-yl)-2,6-difluorobenzamide shows a higher affinity (-9.8 kcal/mol) to the VEGFR2 receptor protein compared to urea derivative inhibitor used as positive control (-9.0 kcal/mol). Interactions between N-(1-chloro-9,10-dioxoanthracen-2-yl)-2,6-difluorobenzamide with VEGFR2 are stabilized through a hydrogen bond with Cys917 at a distance of 2 Å, hydrophobic interactions with Glu883, Glu915, and π-sigma interactions with Val914 and Leu838. Toxicity prediction by the Ames method shows that N-(1-chloro-9,10-dioxoanthracen-2-yl)-2,6-difluorobenzamide is not mutagenic but may induce damages to the liver. Further validation and optimization of structure and activity of N-(1-chloro-9,10-dioxoanthracen-2-yl)-2,6-difluorobenzamide are needed not only to verify its inhibiting potential and but also to optimize its safety and selectivity for cancer drug development.

At present, Indonesia needs a large energy source and the majority of energy use in Indonesia uses fossil fuels, namely fuel oil (BBM), coal, and gas. The use of fossil fuels, besides damaging the environment, is also non-renewable (nonrenewable) and unsustainable. Therefore, to anticipate environmental pollution we need another energy source that can be used by the community. In this case, biobriquette from sugarcane bagasse can be the solution because it is easy to obtain, cheap, and environmentally friendly. This study conducted 3 tests, namely: water content, heating value, and the rate of combustion where the water content testing uses a spectrameter. The samples in this study were biobriquettes with 20 g and 40 g starch adhesives, which produced the best biobriquette quality with fewer adhesives.

Polystyrene is useful product that widely used today. But when it becomes waste, Polystyrene can cause environmental problem such as air pollution, soil contamination, as well as economical resistence due to the increase of space and disposal costs. On the other hand Polystyrene can be converted into fuel. It is expected can be a solution of the problem. The aim of this research is to convert polystyrene plastic waste into useful fuel with catalytic cracking process. Zeolit and Al2O3 was used as catalyst in this research as musch as 8 % feed. Temperature set at 250 oC. At the optimum reaction condition (catalyst Al2O3 and the length of cracking time is 30 minutes) the liquid yield of catalytic cracking process was 29.40 %. Physical properties like density, spgr, oAPI gravity and calorific value of fuel samples is determined and compared to gasoline standard. The result showed that density, spgr, oAPI gravity and calorific value was close to the density, spgr, oAPI gravity and calorific value of gasoline standard.
