Abstract

The abundant peat water in Buluh Cina Village, Siak Hulu Subdistrict, Kampar is a natural potential that can be used for cooking and bathing purposes by processing peat water into clean water that is suitable for consumption. The purpose of this service activity is to treat peat water into clean water. The method used in this service activity is using coagulant and filtration technology. The optimal filtration and coagulant media used for peat water treatment consists of biosand filters with two media namely pumice and quartz sand. The dedication results reduce turbidity and color of peat water and reduce organic content, so that peat water is processed into clean drinking water. The lowest pH value before filtering is equal to 5.93 and the highest pH is found before filtering which is 6.23. This means that before filtering peat water is weak acidic. The lowest sample results after filtration with a slow sand filter that is equal to 6.42 and the highest pH after filtration of 7.5, which means that water is weakly basic. A good pH limit for water is 6.5 to 8.5 so this service proves that slow sand filters are considered effective enough to optimize water pH. Total dissolved solids (TDS) is one of the parameters for determining water quality, TDS shows the amount of solute solids in water. The result of peat water TDS is that the lowest TDS value before filtration is 46 mg / L and the highest TDS is found before filtering which is 49 mg/L. The lowest sample results after filtration with slow sand filter is 49 mg / L and the highest TDS after filtering is 83 mg/L.

Abstract

The potential of the laundry sector, the entrepreneur community / UKM Laundry in Tampan District, which has very potential business potential. This clearly saves the huge potential of the Laundry / UKM business sector. The clothes drying system, which is carried out through the traditional drying method, has long been practised by Laundry UKM entrepreneurs. In particular, the clothes drying activity has long been a source of livelihood for the Laundry UKM community in Panam District. However, in general, the process of drying clothes through a drying method that relies solely on sunlight is not optimal. The process of drying clothes by laundry entrepreneurs in the Tampan District is still done traditionally, namely drying in the sun. This process takes a long time, it takes 2 to 4 days to dry clothes and it also depends on the presence of sunlight. The drying machine is designed to utilize heat from burning coconut shell waste which functions as a heat collector. So that the drying process can take place quickly, at any time and without depending on the sun. Control of the drying temperature is done by opening and closing the air ducts in the dryer. This dryer consists of a solar collector, biomass burning furnace, and drying room (box). The drying room functions as a place for clothes to be dried. The flow of heat from burning coconut shell waste to the drying chamber. The result of drying clothes is better than traditional drying. The drying technology based on coconut shell waste to dry clothes will be applied in the Laundry UKM community in Tampan District, Pekanbaru which is the livelihood of some UKM in Tampan District, Pekanbaru City

Abstract

Groundwater, one part of water resources is the most needed by humans for life. The availability of ground water and the increasing population growth in Tangkerang Labuai Village reguire the use of clean water. This study aims to determine the rock layers that makes up the soil and soil aquifers and the quality of groundwater. For the soil layer, it user the Schlumberger configuration geoelectric method,for the aquifer test, uses the Jacobs step drawdown method to determine the decrease of groundwater level is time. For air quality uses radians where the pH, TDS, turbidity values describe the resistivity value. The results of the research based on data processing on a 90 m long track,ground water is found at a depth of 7-10 m with a resistivity value of 114 m, which is categorized as granite, sand, gravel, alluvium constituent layers with a resistivity value of < 1000 m or the aquifer is partially connected due to the presence of a porous rock layerhaving small pores. To test the aquifer in the well based on the relatively small decrease in groundwater, namely 0.2 and 0.1 cm with a discharge of 0.43 liter/second with a transmissivity value of 971.901 m2/day, categorized as free or connected aquifer. Groundwater could not be consumed from the results as as stated to the regulation of the Minister of Health of the Republic of Indonesia number 492 of 2010, because the pH obtained was < 6.5 or acidic nature and categorized as partially connected aquifers because the more acid of water is formal, the higher the resistivity value is obtained.

Abstract

The Covid-19 pandemic has had a tremendous impact on various sectors of human life. The government has made various rules and policies in dealing with pandemics and the impacts they cause but are more top-down and common which often do not touch on substantive things in accordance with real conditions in the local community. On the contrary, local communities that better understand their environmental situation and conditions are often not involved in determining the rules and policies in addressing this pandemic. Kampung Tangguh as an effort by the community to survive during a pandemic is a form of local wisdom-based community involvement in the community itself in helping the government overcome the Covid-19 pandemic and the impact it causes. Using a qualitative approach through field reviews, interviews, and documentation studies, this paper illustrates the form of community participation in addressing the Covid-19 pandemic. From the results of this study, it is seen that people at the village level or the neighborhood where they live can actively participate together in overcoming the spread and impact of Covid-19.

Abstract

Seawater intrusion has a serious impact on the availability of clean water for the population. Indications of seawater intrusion in several locations in Mundam Village, Dumai City are shown by fluctuations in resident well water from fresh water to brackish water to salt water. This study aims to determine the seawater intrusion zone that occurs using the geoelectric method of the Schlumberger configuration in Mundam Village, Dumai City and to determine the water quality around the research area using several parameters, namely pH, salinity, total dissolved solid, and Turbidity. 1D data processing is carried out with progress software and a 1D cross-sectional model is obtained. This research was conducted on 2 tracks with a distance of 100 meters for each track. The results of the inversion using progress software can be seen that seawater intrusion occurs on line 1, the resistivity value is 0.46 Ωm with a depth of 14.74 – 22 m. Line 2 no longer contains seawater because the distance is more than 1 km from the coast. The depth of groundwater on track 2 is 15.09 – 22 m with a resistivity value of 1.59 Ωm so that at a distance of more than 1 km from the coast it is very good for residents to use drilled wells to get water suitable for consumption.

Abstract

One of the geothermal prospecting areas in Riau is located in Sungai Pinang Village, Kuantan Singingi. Geothermal prospects in this village are characterized by the presence of geothermal manifestations on the surface in the form of hot springs. The purpose of this research is to analyze the rock lithology, the depth of the permeable layer, and the profile of hot springs. The method used is the geoelectric method with the Wenner Configuration. The results obtained in line 1 have a rock lithology of clay, sandstone, limestone, and andesite rocks with a permeable rock layer located at a depth of 1.25–15.9 meters.The results obtained in line 2 have rock lithologies of clay, gravel, and andesite with permeable rock layers located at a depth of 1.25 – 9.26 meters. The hot springs come from underground pressure that forces hot water to the surface through fractures to form geothermal manifestations on the surface.The hot springs found on both lines have resistivity values of 1.19–10 Ωm on line 1 and 0.524 – 9.69 Ωm on line 2.

Abstract

One of the hot spring tourist attractions in Riau Province is Sungai Pinang Village, Hulu Kuantan District, Kuantan Singingi Regency. The geothermal system at that location originates from a geological structure where faults and fractures are pathways for the transfer of geothermal fluids, so it is necessary to identify hot springs. This study aimed to determine the resistivity value of rock layers and to find out the test results for hot water sample content using pH and temperature parameters. The method used is the Schlumberger configuration geoelectric method. Data processing was carried out using progress software with the one-dimensional data type. The resistivity value of the rocks obtained in line 1 has a resistivity range of 39.77 – 594.04 Ωm with a depth of 0 – 23.02 m. Track 2 has resistivity values ranging from 28.41 – 2585.18 Ωm with a depth of 0.29 – 1.06 m. Track 3 has resistivity values ranging from 2.76 – 856.53 Ωm with a depth of 0 – 7.82 m. Interpretation results on tracks 1 and 2 found no hot water because the track's position is far from the hot springs. Hot water is found on track 3 with depths ranging from 0 – 0.04 m and 3.76 – 7.82 m.
