Penelitian tentang prediksi kedalaman dan analisa potensi air bawah tanah di Kecamatan Senapelan Kota Pekanbaru telah dilakukan dengan menggunakan metode beda hingga. Tujuan penelitian ini adalah untuk prediksi kedalaman dan menganalisa potensi air bawah tanah tahun 2018 sampai dengan tahun 2025 di Kecamatan Senapelan Kota Pekanbaru dengan menggunakan program komputer aplikasi MATLAB R2015a. Hasil pengolahan data dimasukkan ke dalam program komputer, sehingga dapat dibuat model garfik kontur dan grafik mesh yang menggambar pola sebaran kedalaman air bawah tanah berdasar model permukaan Kecamatan Senapelan Kota Pekanbaru. Air bawah tanah diprediksi pada kedalaman 16 meter sampai 32 meter untuk tahun 2018 sampai dengan tahun 2025. Hasil prediksi kedalaman air bawah tanah dipengaruhi oleh beberapa faktor yaitu Resepan (R), pengambilan air oleh penduduk (Ed), pengambilan air oleh industri (Ei), pengambilan air oleh fasilitas umum (Ef), pengambilan air oleh pelayanan jasa (Ep) dan pengambilan air oleh peternakan (Et).

Mapping the value of the sedimentary magnetic susceptibility along the Sail Pekanbaru river using Surfer 11 Software has been carried out. The sample consisted of 70 location points consisting of 35 right bank edges and 35 left bank edges. The sampling method uses the grid method. The results of the magnetic level calculation show a range of values from 0,03% to 0,19%.The results of magnetic degree value mapping indicate that the magnetic degree obtained is getting higher from upstream to downstream. The results showed that the suseptibility magnetic value of sediment in the Sail Pekanbaru river ranged from 0,82 × 10-8 m3 / kg to 3,44 × 10-8 m3 / kg, based on this value it can be estimated that the main magnetic particles of the sample are in the Sail Pekanbaru river is ilmenit. The results of mapping the magnetic susceptibility values and mass susceptibility values of the samples indicate that the magnetic susceptibility in the Sail Pekanbaru river from upstream to downstream is less.

Geoelectric is one of the geophysical exploration methods that uses the earth's electrical properties to study subsurface conditions, the geoelectric method has several rules, one of which is Schlumberger's rule. This study aims to determine the composition of the soil layer, so that it can be known that the cause of difficult surface water seeps into the ground based on resistivity values at the HSB Indah Residence. Schlumberger configuration research uses a 300 meter stretch. Resistivity of soil constituent lithology in the study area was generated by processing geoelectric data using one-dimensional progress software. The cross section of the rock structure consists of five layers, namely the first layer is a clay layer with a resistivity value of 13.49 Ωm, the second layer is silt layer with a resistance value of 42.88 Ωm, the third layer is a clay layer with a value of 1.87 Ωm, the fourth layer is a layer of sandstone with a resistivity value of 59.17 Ωm and the fifth layer is a layer of gravel sand with a resistivity value of 443.40 Ωm. This shows that the cause of surface water is always flooded around the housing area, the soil layer is dominated by clay and silt material with a depth of more than 25 meters.

This reseach has been done to know the correlation between spread F appearance and scintillation ionosphere on west region Indonesia. The method has been used is data interpretation using computational way, then all of data is processed using matlab software. The occurance of spread F was minimum in 2008 with it value respectively around 45%. In 2011 the spread F was beginning to increase with it value respectively around 70%. The occurance of ionospheric scintilation was minimum in 2010 with it value respectively around 13%. These occurances were due to a minimum phase of solar activity. In 2013 the scintilation was beginning to increase with it value respectively around 75% in which the occurance was selected for S4 ≥ 0,6. The correlation level between spread F and scintilation is medium, because the value of R aquals 0,4 this case is be affected by solar activity. The value of R is 0 (no correlation) at weak solar activity and 0,6 at high solar activity.

Comparison of heavy metal (Cu, Fe and Zn) content of Siak river water between before and after purification process has been done using an experimental method. The processstarted by taking sample of the Siak River water at a distance of 1 meter from waste sewage system of rubber manufacturing industry PT.RICRY Pekanbaru. Concentration of pre-filtered samples was measured by atomic absorption spectrophotometer (AAS), then each sample was filtered five times. The result of pre-filtered samples characterized by (AAS) of Cu, Fe and Zn were 0.3809 ppm, 0.0051 ppm, and -0.0012 ppm. The absorption percentage of samples characterized by (AAS) for Fe, Zn and Cu were 12,02 %, 33,33 % and 72,54 %, respetively (type I) and 33,15 %, 2,70 % and 80,39 % respetively for type II. Based on the obtained data, it was concluded that the purity instrument of type I was better than type II for water treatment.

A research has been done on analysis of concentration of heavy metals (Cu, Fe, Zn) electrical conductivity and density of the Gaung river water. The method that used in this research was an experimental. The samples of Gaung river water in the village of Semambu Kuning was taken three times in each point: the Dusun Terentang, Dusun Sejahtera, and Dusun Mulia. Measurement of the concentration of heavy metals was performed by using Atomic Absorption Spectroscopy(AAS), while the electrical conductivity measurements were performed using conductivitymeter and density was measured by using a hydrometer. The results showed that the concentration of iron(Fe) from each points was 1.28x10-6 kg/l, 1,25x10-6 kg/l, and 1,32x10-6 kg/l, respectively. Concentrations of copper(Cu) oneach points was 0.0015x10-6 kg/l, 0.0051x10-6 kg/l, and 0.0053x10-6 kg/l. Concentrations of Zn(zinc) was found to be 0.0310x10-6 kg/l, 0.028x10-6 kg/l, and 0.0337x10-6 kg/l. which the electrical conductivity was 192,33x10-4 mho/m, 197,23x10-4 mho/m, and 199,9x10-4 mho/m.

This research is to determine the absorption of solar radiation by solar module which layered by polyester window films with the darkness of 40, 60, and 80% of the output power from the polycrystalline silicon solar module. It is then compared with the standard module. The current and voltage data of solar module are recorded by using Solar Charger Controller Model VS2024N every 1 hour from 10:00 am to 17:00 pm during 3 days. The solar module power output decreased with increasing the time. The power output of solar modules layered by window film influences significantly from 23.53% until 24.39%. The maximum output power is obtained from the window film darkness with level of 60%.

Activated carbon from shells of oil palm has succesfully been made. It was carbonizedat 400 ̊C, 500 ̊C and 600 ̊C for 20, 40 and 60 minutes. The physical activation wascarried out at the temperature of 900 ̊C for 20, 40 and 60 minutes. This activation wasdone by flowing the water vapor as an activated agent. The objective of this researchwas to characterize palm oil shells that was carried out through proximate test whichwere water content and ash content, the absorbane of activated carbon toward iodinevalue and yield. The best results after carbonization were the samples that werecarbonized at 600 ̊C for 60 minutes, with proximate content : water content of 4,5% andash content of 9.7%. The iodine number at activation of 900 ̊C for 60 minutes was 353mg/ gr and yield of 48%.

A research has been done on physical analysis of clean water treatment at PDAM Tirta Siak Pekanbaru. The methods that used in this research was an experimental in order to analyze water treatment system, water debit which was distributed in the main pipe, and water velocity in the pipe. Raw water used in the water treatment plant uses water from the Siak River using intake. Intake on this water treatment uses two pumps with capacity of 140 liters / sec are used interchangeably to collect water. Raw water treated by coagulation, flocculation, sedimentation, filtration, and disinfection. Incoming raw water to be processed and distributed to the reservoir as the water ready to be distributed to consumers. Reservoir water discharge was obtained for 110 liters / sec or 410.4 m3/sec. Obtained debit water out of the water volume ratio of a specific time range that depends on the size of the pressure in the pipe. Based on the results of the average debit coming out in May 2014 at 9:00 to 10:00, 10:00 to 11:00, 11:00 to 12:00, 12:00 to 13:00, 13:00 to 14:00, 14:00 to 15:00 is 475,142 m3/sec, 443,594 m3/sec, 426,883 m3/sec, 431.755 m3/sec, 430.432 m3/sec, and 425.980 m3/sec, respectively. Water flow rate obtained 0.604 m/s, 0.610 m/s, 0.605 m/s, 0.612 m/s, 0.629 m/s, and 0.673 m/s, respectively.
