Abstract

Vertical Electrical Sounding (VES) method is one of many methods in geophysics that was conducted in this research at Toro Jaya, Langgam, Riau. The aim of this research is to investigate and locate the depth of groundwater layer (aquifer). Data acquisition of VES was carried out using GEOCIST with Schlumburger configuration of electrode. There are four VES point in this research with various length of cable ranging from 135 m up to 200 m. From four VES point shown two different of resistivity value range. Very low resistivity value with range 0,34 – 0,9 Ωm interpreted as aquifer layer. The aquifer layer of research area divided into two types which are unconfined aquifer and confined aquifer. Meanwhile, another resistivity value ranging from 1,69 – 7 Ωm was interpreted as clay layers.

Abstract

Saltwater intrusion becomes a common problem in coastal area. Northern coast of Bengkalis Island in Riau, Indonesia that contiguously to Malacca Strait is experiencing the problem particularly in Selat Baru area which considered as developing area and most of the people live close to the sea. Dug well is the main source of groundwater that had been used by the population in Selat Baru and as the increasing of land occupation, the demand of clean water is rising up followed by the number of dug well. A study of groundwater monitoring was conducted to identify the zone of saltwater intrusion. Field observation had done by measuring the water level and physical parameters of groundwater such as taste, pH, electrical conductivity (EC) and total dissolved solid (TDS) from 110 existing dug wells. Some conus feature had found from groundwater elevation map which indicated lower water level caused by excessive groundwater pumping. Generally, pH shows values from 6-8 that was still in range of water quality standard, but there are 20 wells (18%) that have pH below the water quality standard (slightly acidic water). Similar pattern had been observed from Electrical Conductivity (EC) and Total Dissolved Solid (TDS) map, higher value of EC and TDS was dominant in the northern part of study area and lower value in the south. Groundwater taste map also revealed the identical condition with EC and TDS map which dominated by brackish and saline water in the northern part. Therefore, the study area had been divided into two zones of groundwater saline water zone possibly caused by the saltwater intrusion in the northern part and freshwater zone from the center to the southern part.

Abstract

Pekanbaru, Indonesia is connected by four big bridges, Siak Bridge; I, II, III and IV. The quality of the Siak bridges deteriorated seriously at this time. Geological mapping for the land subsidence potency was conducted using small Unmanned Aerial Vehicle (UAV) in the Siak Bridge areas. The study of the Siak bridges are supported by the Differential Interferometric Synthetic Aperture Radar (DInSAR) analysis using ALOS PALSAR satellite data, and the deflection observation that occurs in Siak III Bridge was observed by field measurement. The results of 3D model analysis showed that there is no negative land deformation. DInSAR analysis shows the amount of positive deformation of Siak I is 81 cm, Siak II is 48 cm, Siak III is 89 cm, and Siak IV is 92. Deflection on Siak III Bridge was detected at around 25-26 cm. These models could be used as a new way of measuring the bridge deformation on a big scale.

Abstract

In the era of society 5.0, memory institutions such as museums and libraries need to implement information technology, starting from digitizing collections to information dissemination. However, the new technology development carried out by the Sang Nila Utama Museumis limited to making a one-way website and information system. Social media is a two-way platform that has great potential to be used to disseminate information about the Sang Nila UtamaMuseum directly to the public's smartphones. Community service activities carried out in the form of counseling on the use of chatbot applications that are integrated with Telegram. Counseling participants were provided with the provision to add chatbot databases through web-based applications and were guided touse Telegram chatbots as well as ways to carry out promotions for museum visitors so they could use the facilities which were expected to attract public interest in browsing available information. Based on the results of the usability testing questionnaire, all participants strongly agreed that the information contained in the application was organized, the application was easy to use and overall,the application supported the information dissemination process in the museum properly and optimally. Overall,the application works according to the functions that have been designed which is indicated by a high average value of 4.48. Partners feel very satisfied and recommend that similar service activities be carried out regularly

Abstract

Stability on the slope was considered important for the safety of people who pass through the highway. Failure of slopes on highways can cause losses especially roads had an important role in community activities. The research was located on the Riau – West Sumatra Km 165. The purpose of this research was to find out treatment or mitigation that can be given to the research slope and know the soil classification based on the analysis Atterberg Limit. The research slope was divided into 3 parts using analytical Rock Structure Rating (RSR) method based on different slope conditions. And 1 part of the slope has become soil using the analytical method Atterberg Limit. Treatment or mitigation that can be given to the research slope, namely the use of rock shopandshotcrete based on the RSR diagram and the use of rock embankments to resist landslides.

Abstract

This study area is administratively located in Parit Indah District, Bukit Raya District, Pekanbaru City, Riau Province. Geographically, the research area is located at coordinates 0° 28' 30.92" N 101° 28' 9.45" E N 0° 27' 25.63" - 101° 29' 47.30" E. The aim of this study was to find out the effect of peat soil types on subsidence. The data collection method in this study was carried out using sieve analysis, water content analysis, specific gravity, subsidence analysis, and soil testing in the laboratory. The effect of peat soil on subsidence has a significant effect between the type of peat and subsidence, the higher the maturity level of the peat, the lower the level of subsidence on peat soil. Based on the study's results, the soil consolidation test with a depth of 75cm-3m had a soil settlement value of 0.467. It is recommended to do this to reduce the impact of subsidence in the land area such as the research area so that it does not have too much impact on the construction which is carried out by hardening the location using the vertical wick drain method, as well as for building foundations it can be done using chicken claw foundation.

Abstract

Groundwater sustainability has become a serious issue as a water resource needed by society. Therefore, electrical Resistivity Imaging was carried out at Rumbio Jaya, Kampar, and Riau to study groundwater aquifer's electrical characteristics. The equipment used is a Geocis resistivity meter with (32) multi-electrodes alignment. Wenner configuration electrode was applied in this survey. The 2-D Electrical Resistivity inversion results indicate there are three resistivity zones; (1) Low resistivity value (0.0093 4.84 m) representing conductive clay; (2) intermediate resistivity value (1.07 171 m) indicate as potential aquifer layer; and (3) a high resistivity value (61 4000 m) occupying as bolder of rock. All the zones have different thicknesses and depths, but mostly clay layers dan boulders are shown as lenses in the aquifer of the study area. Meanwhile, the aquifer layer is found easily at a depth of 1 meter up to 30 meters.
