Groundwater is the main water resource especially for daily water needs. Population growth and urbanization have increased demand for water while the availability of groundwater has decreased both in quality and quantity. Various human activities also produce industrial, agriculture and municipal waste that can pollute groundwater through leaching process. The purposes of this study are to determine the quality of groundwater around tofu industrial factory and its evaluation for drinking water based on Health Minister Regulation No.492/MENKES/PER/IV/2010 and Government Regulation No.82 2001.The temperature, pH, total dissolved solids (TDS) and electrical conductivity (EC) were measured by using YSI-Pro. Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) were measured based on SNI 06-6989.2.2009 test method and SNI 06-698.72.2009 test method, respectively. Physically, groundwater had temperature average 28,60C, TDS 243 mg/L and EC 396 µS/cm. Almost all groundwater were acidic with pH average 5,6 and did not meet the drinking water quality requirements. Groundwater had COD average 78 mg/L, BOD average 36 mg/L and it were classified into moderate-heavy pollution. It indicated that groundwater may have been contaminated by organic material from tofu industrial wastewater. Therefore, groundwater should not be used as a source of drinking water.

Groundwater plays important role as the main water resource for human needs. The vulnerability of groundwater to contaminants both naturally and by human activities can be not avoided as a trigger for groundwater quality degradation. Hydrogeochemical become important highlights in groundwater studies because groundwater conditions in quality and quantity influenced by the geological formation of rock minerals in aquifer. Naturally, the condition of the research area which consists of peat swamps can also affect the characteristics of groundwater. The aims of this research are to determine groundwater types and groundwater facies in study area with an analytical approach using stiff diagram and piper diagram. The method used was purposive sampling by collecting data from dug wells at the research site. 5 samples from dug wells were used as representatives in the groundwater facies analysis. The groundwater facies analysis was carried out by measuring the concentration of major ions such as Na, K, Ca, Mg, Cl, SO4, and HCO3. The highest groundwater level was in the northern part of study area (7,84 m) while the lowest groundwater level was in the southwest part of study area (2,05 m). The results showed three types of groundwater based on stiff diagram as sodium chloride (NaCl), sodium sulfate (NaSO4) and magnesium sulfate (MgSO4). The lithology conditions that composed the aquifer affected the facies or origin of groundwater. The alluvium layer in the research area which rich in sodium (Na+) minerals with chloride (Cl-) or sulfate (SO42-) anions forms chloride sulfate facies (Cl+SO4) which were located in the middle to the south of the study area and sodium (potassium) chloride (sulfate) facies (Na(K)Cl(SO4)) which were distributed in the northern part of study area.

Cocoa fruit is one of the fruits with local wisdom that can benefit Indonesia. But its used still limited to the fruit, while the peel of the cocoa fruit is only discarded so that it becomes a waste that will have an impact on the surrounding environment. We can minimize the amount of waste from the peel of the cocoa fruit is to make something useful that is a potential drug raw material. In this study a qualitative test was conducted to determine the secondary metabolite content of the cocoa plant. Flavonoid test results have positive results that indicate a change in color. The results of phenolic and tannin testing have positive results that indicate the formation of bluish black or green. Saponin test results have positive results that indicate the formation of foam. Triterpenoid test results did not show positive results. Based on the results of the study, cocoa peel waste has the potential to be used as an alternative to potentially medicinal raw materials.

Environmental problems are global issues caused by low public awareness of the importance of environmental management. One factor is the environmental pollution generated by waste. The problem of waste is closely related to the lifestyle and culture of the community. If waste management does not get the attention of various parties, it will make environmental conditions worse and human health conditions also go down. Therefore, awareness of the importance of waste management needs to be instilled since childhood. This activity was carried out at SDN 007 Pangkalan Baru, Siak Hulu District, Kampar Regency. Based on the activities that have been carried out, most students do not yet understand how to classify and process waste to be economic value so the education should be given to the students. This activity can be said successful because of the high enthusiasm and participation of students in answering the questions that given based on the material that has been delivered.
