Abstract

The comparative research was conducted from October 2016 until January 2017 at two companies namely PT. AIP Teluk Siak Factory (TSF) and PT. BNS Mandah Factory (MDF) in Riau Province. The purposes of the research were to analyze the correlation between oil and palm kernel (losses) that is entrained fuel (fibers and shells) with opacity emissions boiler in TSF and MDF, and to analyze the impact of ambient air SO2 levels on capacity pulmonary function palm oil mill employees (TSF and MDF) with controll variables personel protective aquipment, age, smoking habits, and tenure.Based on the results, The correlation strength of oil loss in fiber cyclone, kernel loss in fiber cyclone, and kernel loss in winowing with boiler opacity in TSF and MDF is low correlation (R value of 0.320). The simultaneous and partial oil loss in fiber cyclone, kernel loss in fiber cyclone, and kernel loss in winowing were not significantly affect the boiler opacity in both factories (F test and t test of significance  > 0.05). R2 value of 10.2% indicates the magnitude of losses effect on opacity. This analysis explains that the losses are not the dominant factor affecting the boiler opacity. The boiler opacity is influenced by quality and balance fuel with oxygen, continuity process in mill and optimization of boiler performance as the operation practice, maintenance and boiler sparepart replacement. The impact of ambient air SO2 levels on capacity pulmonary function when controlled by age and tenure showed significant values (p < 0.05). Age and tenure are factors that differentiate magnitude of the impact of ambient air SO2levels on capacity pulmonary function. While the impact of ambient air SO2 levels on capacity pulmonary function when controlled by personel protective aquipment (PPE) and smoking habits did not show significant values (p > 0.05) in both factories. PPE and smoking habits are not factors that differentiate magnitude of the impact of ambient air SO2 levels on capacity pulmonary function.

Abstract

The research was conducted on May – June 2007 in side of Siak River at Kecamatan Rumbai Pesisir, Pekanbaru. The purposes of research is know that one of the impacts of pollution on Siak River is diseases carrying water had increased (diarrhea and skin diseases). Therefore, itneeded a research concern on the advantage effects of river waters toward diarrhea and skindiseases of community side Siak River (case on Kecamatan Rumbai Pesisir, Pekanbaru). Thehypothesis was that pollution on Siak River caused high prevalence of case on diarrhea and skindiseases, oppositely, the people had not used waters from Siak River had case by lowprevalence. The research design was conducted by cross sectional method where measurementand observation was conducted at the same time (once periodic) and sampling purposively.Then, data analyses got by chi square (X2) to determinate a correlation and the strength wasmeasured by odds ratio (OR) value. The result of analyses was show that toilet activities(bathed, washed and water closet) had proved that people used river water would had higherrisk affected by skin diseases than people had not used it. Bath activities was OR = 1,659 thatmeans people had take bath in Siak River would higher affected by skin diseases 1,659 timeshigher than people had not bath in river. Washed cloth activities was OR= 2.032; washed dishand kitchen tools OR = 1,737 and used water closet OR = 2,217. There was not correlationbetween the toilet activities (bath, wash and water closet) with diarrhea disease; significantly, itcaused diarrhea disease usually affected by drinking water that disturbance of digestive system.But, in this research might not proved correlation between the using drinking water withdiarrhea disease. It might caused by few sample or although people didn’t used the water river as drinking water, directly, but still affected by diarrhea. And people percentage affected bydiarrhea disease was great in 25 percent.

Abstract

Clean water according to Permenkes RI No 416 / Menkes / Per / IX / 1990 is water that used for daily needs whose quality meets health requirements and can be drunk after cooking, one of the government's efforts to meet the clean water needs of the community is the Pamsimas Program. The Pamsimas Program is one of the programs and concrete actions of the government (central and regional) with the support of the World Bank to improve and meet the needs of drinking water supply, sanitation to improve the level of public health, especially in reducing the number of diarrheal diseases and other diseases that are transmitted through water and the environment. Muaro Tombang Village, Sungai Manau Village and Bukit Kauman Village are the three villages in Kuantan Mudik Sub-District that have not had access to 100% clean water. Indicators of success and sustainability of the Pamsimas Program are the quantity and quality of water sources, management policies and management strategies for the Pamsimas Program. The quantity of water in the three villages in terms of discharge and minimum reservoir capacity meet the needs of the community, the water quality in the three villages there are several parameters that do not meet the quality standards of the Minister of Health Regulation No. 416 of 1990 concerning Clean Water Quality Requirements, so it needs to be treated for water Pamsimas Program. The community's perception of the socio-economic and management policies of the Pamsimas Program Muaro Tombang Village and Sungai Manau Village is included in the agreed category, while the community's perception of the socio-economic and management policy of the Pamsimas Program in the Bukit Kauman Village is in the neutral category. The right strategy used for the management of the Pamsimas Program in the three villages is the aggressive strategy (Growth Oriented Strategy), namely the development of the Pamsimas Program by utilizing the strengths of the opportunities that have been identified.
