Abstract

Wastewater in an industry which is often called liquid waste is a by-product produced by several human activities. Liquid waste pollution from industrial effluents containing lead (Pb) in dug well water used by the community for daily needs can cause poisoning and health complaints. This study aims to determine the content of lead (Pb) in the liquid waste stream and well water as well as public health complaints around the pulp and paper industry. This type of research was descriptive with the observational method. Liquid waste from the paper and pulp industry is known to contain heavy metal type lead (Pb), if it pollutes the environment around the industry it can cause various negative impacts for the community. There were 2 samples of dug well water 90 meters that have lead content above the quality standard, namely in well 8 and well 10 with lead content of 2,998 mg/L and 4,247 mg/L while for other dug well water it did not exceed the threshold value with results below 0.0085 mg/L. Based on the results of interviews with 40 respondents, most of the respondents who used dug well 8 and well 10 water experienced health complaints such as skin redness and itching on the hands and arms, and the most experienced redness, itching, and hot eyes after using dug well water contaminated with lead (Pb).

Abstract

The car wash wastewater has a proportion of detergent  and it can cause considerable impacts to pollute the environment and health if they are not processed in well. SSVF CW is one of  an alternative wastewater treatment, because it has the advantage such as wastewater flowing below the surface of the media so it  reduces the smell of wastewater. The objective of this study was to determine the  removal efficiency of reducing pollutants in the wastewater of treated car wash by Constructed Wetland and the influence of Chrysopogon zizanioides rhizosphere depth in supplying DO distribution. This experimental laboratory scale study used 2 PVC for reactor. Each pipe has 4 sampling points. The DO was measured from different depth, while the other parameters were from the effluent. The ratio of the media used was  1:3:2:4 from the top to the bottom. The SSVF CW system had high TSS removal efficiency of 94.74%, while the removal efficiency of COD, Detergent, and Phosphate was76.21%, 54.54%, 30.65%, respectively. DO distribution at a depth of 84 cm in both pipes increased even though the root zone was only 26.5 cm.

Abstract

Tamarind (Tamarindus indica) is a versatile plant, findable in Indonesia (Java, Bali, North Sumatra, West Kalimantan, and South Sulawesi). The leaves are green to brown, round, 1-2.5 cm long and 4-8 mm wide, rounded tips, rounded base of blades, and flat edges. The content contained in tamarind leaves such as flavonoids, tannins, saponins, and alkaloids is believed to inhibit Propionibacterium acnes activity. This study aims to determine the effect of tamarind leaf extract ointment in controlling the growth of the bacteria Propionibacterium acnes that triggers acne. This study applied a Completely Randomized Design with 96% ethanol maceration method. Propionibacterium acnes was evidenced by the inhibition zone formed. The diameter of the inhibition zone of the 25% ointment was 1.235 cm, the 30% concentration was 1.385 cm, the 35% concentration was 1,680 cm, and the ointment base was 0 cm. The ANOVA test showed a significant value of 0.000<0.05, so there was a significant difference between the inhibition zone and the 95% confidence level. The results of Post Hoc test were P<0.05, meaning that there was a significant difference between the bases with formulas 1, 2, and 3. Thus, tamarind leaf extract ointment had a strong inhibitory effect on Propionibacterium acnes.

Abstract

Staphylococcus aureus bacteria are resistant to several kinds of antibiotics, so there is a need for natural antibiotics derived from plants, namely aloe vera. The objective of this study was to determine the effect of aloe vera leaf extract in inhibiting the growth of Staphylococcus aureus bacteria. The type of research used was experimental using the disc diffusion method with a total of 25 samples with five concentrations of 20%, 40%, 60%, 80% and 100% then the data were analyzed using the One Way ANOVA test. The result is that aloe vera extract can inhibit the growth of Staphylococcus aureus bacteria, it is proven by the presence of a disc zone at 100% concentration with a diameter of 11.5 mm. The results of statistical analysis with the One Way ANOVA test, in a value of 0.000, meaning that there was a significant difference. The conclusion obtained is that aloe vera extract can slow down the growth of Staphylococcus aureus bacteria but based on the standard value of sensitivity of an aloe vera extract bacteria with the highest concentration it cannot be used as an antibiotic because it is less than the standard value of 14 mm.

Abstract

Antihypertensive therapy used in patients with End-Stage Renal Disease undergoing hemodialysis is objected to decrease mortality related to ESRD complications. Nonadherence to antihypertensive therapy can lead to uncontrolled blood pressure. This study aims to determine the level of adherence to antihypertensive drugs and its correlation to blood pressure control in ESRD patients undergoing hemodialysis. It was an observational analytic study based on the cross-sectional method. Sixty  person subjects were involved using the quota sampling technique. The level of adherence was examined using the Modified Morisky Scale questionnaire. Blood pressure data were obtained from mean values of respectively pre, during, and post-hemodialysis blood pressure within four hemodialysis visitations. The data was examined bivariately using the Chi-square test with a 95% confidence interval. The results show most patients have high level of adherence to antihypertensive treatments (55%) yet have uncontrolled levels of blood pressure (95%). The Chi-square analysis found there is no significant relationship between the level of adherence to antihypertensive therapy and the average blood pressure level of ESRD patients who undergo hemodialysis (p-value 0,301). This finding suggests a consideration in monitoring the effectivity of hypertension management that adherence is not a single significant factor affecting the successfulness of medication.

Abstract

Kesambi is a plant widely used by people of Timor Island. Flavonoid content of Kesambi is potential to be used as immunomodulators. This study aimed  to study the effect of Kesambi bark extract on lymphocyte count and spleen index of male mice as an indicator of their immune responses. Research included identification of phytochemical compounds macerated from Kesambi bark, lymphocytes count and spleen index calculation. Mice injected with sheep erythrocytes were treated orally with three doses of Kesambi extract (0.113 mg/g BW, 0.491 mg/g BW, and 0.712 mg/g BW) for 10 days. Lymphocyte count using blood smear method was carried out on day 0, 5 and 10, while lymphocyte count using hematology analyzer and spleen index measurement were performed after mice sacrificed. Kesambi bark contains alkaloids, flavonoids, tannins, and steroids. Treatment with Kesambi bark extract reduced mice lymphocyte count. Administration of 0.491 mg/gr BW dose reduced the mice lymphocytes count close to the number of lymphocytes in the negative control group. The spleen index of mice had no correlation with changes in the number of lymphocytes. This preliminary study shows a potential use of Kesambi bark extract as a natural immunosuppressant.

Abstract

God created Indonesia with a tropical climate that is very appropriate to support the development of straw mushroom cultivation (Volvariella volvaceae). One of the stages of mushroom cultivation sequentially is pasteurization. This study aims to determine the effect of pasteurization stages, the accuracy of the pasteurization temperature, and the factors that influence the growth of straw mushrooms. The method in this study was carried out using livestock manure, with a composition of 400 gr goat manure and 500 gr rabbit manure. The pasteurization stage is maintained at a temperature of 60-700C with a humidity of 80-90%. The watering interval at the observation stage was 4 days with a frequency of 40% in experiment 1 and every day or a frequency of 100% in experiment 2. The results showed that the pasteurization stage was very influential on the mushroom growing media. Inaccuracy in pasteurization resulted in many weeds that thrived, thus inhibiting the growth of straw mushrooms. The optimal temperature in the pasteurization stage is 60-900C. The factors that influence the growth of mushroom are the selection of materials as fertilizers for mushroom cultivation, temperature, humidity include interval and frequency of watering, pasteurization process, weeding the contaminants, and time of observation.
