Abstract

The development in textile industry results in the increase of the use of non-organic materials in human life, such as the use of dyes that cannot be decomposed naturally, such as the use of artificial dyes in textile industry and other similar fields. This implies that if those artificial dye are not carefully managed, they will have a definite impact on the environment, such as water pollution where those substances contaminate clean water and therefore will be very dangerous for human daily needs of water for drinking, bathing and other needs. This in turn will cause various diseases in living things and pollute nature as well. The purpose of this study is to figure out the effect of methyl orange degradation by the addition of TiO2 photocatalyst. In this study, 10 ppm orange methyl solution were used, where 5 ml of orange methyl were dissolved in 5 ml of water then added with TiO2 and then irradiated with UV for 180 minutes. By calculating the degradation of methyl orange every 10 minutes, which was measured using a UV-Vis spectrophotometer. The finding shows that the longer the irradiation takes place, the more desirable degradation of methyl orange is desired. The results obtained from 180 minutes are absorbance values that are worth 0.8 down to 0.3.

Abstract

Tuberculosis is a serious health problem that should be concerned. According statistic of The World Health Organization (WHO) show there are 1,7 million deaths due to tuberculosis. Indonesia inclue one of 3 highest incidence of tuberculosis cases in the world. This study aimed to determine the number of leucocytes and erithrocyte sediment rate (ESR) with pulmonary tuberculosis before and after administration of the anti-tuberculosis drugs (OAT). This study used description crosssectional research design. Observations were carried out in patients with tuberculosis who received therapy for 6 months OAT agains leucocytes and ESR before and after treatment. Subjects were new case of pulmonary tuberculosis with acid fast bacilli (BTA) positive and BTA negative Rontgen positive in Dharmasraya district. Materials such examination whole blood samples with EDTA anticoagulant. The result subject are 30 people. Examination of leucocytes and ESR performed before and after administration of the OAT. Result of data analysis showed that changesin the number of leucocytes significance value p=0,000 (< 0,05) and ESR significance value p=0,000 (< 0,05). This suggest that there are significant differences in the number of the leucocytes and ESR before and after administration of the antituberculosis drugs.

Abstract

Increasing uses of chemicals in the laboratory result of waste substances increased. If those wastes are not carefully managed , various pollutions in the environment will occur. The research deals with the use of a simple filtering for laboratory type liquid waste before disposal. This study took the wastewater IAIN Batusangkar chemical laboratory as the object of research. The tools used to measure the concentration of waste are pH meters and TDS meters, with waste analysis before filtering are color: orange, temperature: 25.5°C, pH: 3.1, TDS (dissolved solids): 11.16, Salt (salinity level ): 8.38, COND: 16.78 mS and a waste volume of 300 ml filtered using simple tools and materials, tools with a height of 23 cm and supported with such materials as sponges, wood charcoal, sand, gravel, coconut fiber, cotton, small stone, with a height of each material in the tool that is 3.5 cm. The results shows that the simple filtering instrument for laboratory waste worked quite well, with a one-time analysis of waste where the results are as follow color: clear, temperature: 25.3°C, pH: 6.2, TDS: 13.23, SALD: 9.93, COND: 19.88 mS, volume of waste: 150 ml. It can be concluded that filtering is successfully filtered waste is approaching the normal pH of pure water that is 7.

Abstract

The purpose of this research was to know the influence of the addition of Ginger flour in the feed to the value of the levels of lipid and protein Broiler meat. These researches were conducted that used Soxhlet method to tested the lipid quality and Kjeldahl method to tested the protein. The sample were used Broiler aged 1 weeks up to 2 weeks, after 2 weeks old chicken was divided into 4 treatment groups of 6 each control group (P0) without treatment, P1 with addition of ginger flour in feed 2.5%, P2 in the addition of ginger flour in the diet of 5%, P3 with the addition of ginger flour in the feed as much as 7.5%. After 42 days old, Broiler conducted sampling of meat in the treatment for the examination of the levels of lipid and protein. The Data obtained are then analyzing used a One-way Anova. The result of these researches is in the range of lipid quality: P0 (8,33%), P1 (6,33%), P2 (5,25%), P3 (5,08%) After analyzed have done it shown there were differences that significance (p>0,05). Result of checked of protein quality: P0 (5,59%), P1 (5,32%), P2 (5,36%), P3 (5,45%)  After analyzed were done there is no significance difference (p>0,05). The higher the percentage of ginger flour, the lower the fat content of broiler chicken.
