Abstract

Peat water has a brown color, humic acid content, organic substances, iron and pH levels are very high. To overcome the problem of peat water to be made clean water need to be processing first. Continuous processing of peat water includes; Neutralization, aeration, coagulation – flokulation, and filtration is a complete set of processes but is packaged in a simple form. This process is designed according to the condition and level of education of rural communities in peat water treatment. This study was conducted at a shelter in the village of Peunaga Cut Ujong Meurebo West Aceh. This research aims to reduce acidity, color, turbidity, flavor, iron (Fe), Zeng (Zn), organic matter, nitrate (NO3), and Nitrit (NO2). The research method is an experimental that is directly applied in the field. From the laboratory results in the UPTD Health Banda Aceh has been conducted test water quality before and after processing there are significant results. The results of experimental studies through the simple design of continuous processing using natural materials such as gravel, sand, charcoal and palm fiber and the chemical filling of the capor and alum obtained the results of color dissipation achieved 93.3%, pH of 98.3%, turbidity/cloudiness reached 91.9%, organic substance (KMNO4) of 73.3%, hardness of 39.7%, iron (Fe) 94.6%, zinc (Zn) of 91.09%, Flurode 77.33%, Nitrate (NO 3) of 80.04%, and Nitrit (NO 2) 99.31%. Meanwhile, the result of peat water is no smell and feel. The results of this trial are still under the standard quality of Permenkes RI No. 416/Menkes/PER/IX/1990 on the water quality requirements.

Abstract

The objectives of this research are: (1) To know the effectiveness of lowering the rate of liquid waste COD stamp batik. (2) To know the most effective dose of the EM-4 in lowering the COD levels of liquid waste of stamp batik. (3) To know the day of how many EM -4 is most effective in lowering COD's liquid waste stamp batik. The study used the complete random design of the factorial pattern of dosage EM-4 0 ml/L, 10 ml/L, 15 ml/L and prolonged incubation for 1 day, 2 days, 3 days. The Data obtained is analyzed using two-lane analysis (Two Way Anova). Based on the results of the analysis of the treatment EM-4 and the old incubation against the liquid waste stamp batikobtained the following results: At a group of doses acquired F count = 4209.382 > F table 5% = 3.55, then H0 rejected or there is a real influence of various doses of EM -4 which is used against COD levels. At the time group gained F count = 77.756 > F table 5% = 3.55, then concluded that there is a real influence of incubation time against the rate of COD waste car stamp batik. The most effective EM-4 dosage to lower COD levels of liquid waste stamp batikis 15 ml/l which is capable of lowering COD levels by 96.24% and the most effective prolongedincubation time is the first day. Keywords: Effectiveness, Prolonged incubation, EM-4, COD, Waste batik stamp.

Abstract

Herbal plants are plants that have a function in health as medicine. There are lots of plants that can be used as herbal medicine, one of which is the basil plant. Basil leaves contain chemical compounds including saponins, flavoniods, tannins and essential oils. The main ingredient in basil is essential oil. The essential oil of basil has the potential as an antibacterial. The purpose of this study was to analyze the effectiveness of basil leaf essential oil in inhibiting the growth of Staphylococcus aureus bacteria based on the standard antibiotic inhibition zone according to CLSI. This study used a quasi-experimental research design (Quasy Experiment) with a purposive sampling technique. The population of this research is basil (Ocimum sanctum Linnaeus). The samples used were basil essential oil concentrations of 30%, 32%, 34%, 36%, 38%, 40%, 42%, 44% and 46%. Then tested the antibacterial activity using the diffusion method. Based on research the average inhibition zone at a concentration of 30% inhibition zone formed was 15 mm, 32% concentration was 18 mm, 34% concentration was 16.67 mm, 36% concentration was 15.67 mm, 38% concentration was 17.67 mm, 40% concentration was 22.33 mm, 42% concentration was 16.33 mm, 44% concentration was 18 mm, 46% concentration of 21.33 mm. The conclusion in this study is that there is effectiveness of basil leaf essential oil with the interpretation of Sensitive results in inhibiting the growth of Staphylococcus aureus bacteria by the diffusion method based on the standard antibiotic inhibition zone according to CLSI.
