Abrasion and sedimentation are events that usually arise due to the movement and accumulation of material carried by ocean currents. Severe damage occurred in coastal areas such as on Bengkalis Island. Research on the initial motion of grains, especially on peat material, is very interesting to study. This study aims to analyze the relationship between flow velocity and grain diameter at the be…
This study aims to analyze the financial feasibility of investing in the Pekanbaru-Dumai toll road infrastructure project through a stochastic (probability) approach. This study uses random data with financial variables in the form of data on national economic indicators (Bank Indonesia Certificate, Riau Province Inflation, Jakarta Inter Bank Offer Rate) and investment costs for the Pekanb…
Daya dukung tanah dapat didefinisikan sebagai kemampuan tanah untuk menopang beban pada pondasi struktur di atasnya. Dalam menentukan daya dukung pondasi, data penyelidikan tanah yang umum digunakan adalah berdasarkan Cone Penetrometer Test (CPT) atau Sondir Test yang berupa nilai tahanan ujung (qc) dan tahanan gesekan (qs). Tujuan dari penelitian ini adalah mendapatkan peta yang menggambarkan …
Bengkalis Regency has rice fields with an area of 5,014 ha. The extent of this rice field is a potential that can support the availability of food to meet local and regional needs. One of the irrigation areas in Bengkalis Regency is the Daerah Irigasi Rawa Sepotong in Langkat Village. This irrigation has an area of 326 ha and is a rainfed irrigation area that only utilizes rainfall to meet …
Peat is spread wide in Sumatera Island, especially in Riau Province, Indonesia. Peat is included in the problematic soil because it has a low bearing capacity. The use of helical pile foundation on peat is one of the innovations to increase the peat’s bearing capacity. In this research, numerical modelling of single helical pile foundation load test on peat will be carried out, based on the f…
Laundry is a business or micro business that is engaged in washing or ironing clothes. The laundry services is very helpful for people living in urban areas, especially those who do not have much time to wash clothes. Apart from having a positive impact, the rise of the laundry business actually has a bad effect on the environment. Usually the detergent wastewater resulting from laundry activit…
ABSTRACT Coal was a fossil fuel. The general sense was a combustible sedimentary rock, formed from the deposition of organic matter, primarily the remains of plants and were formed through the process of coalification. One of the coal deposits was in Bangko Tengah Suban Jeriji, Muara Enim Regency, South Sumatra Province. This research examines the design of the mine pit geometry by taking …
The distribution of locations and the number of ideal rain stations will represent rain events to support the accuracy of analytical information in an area. The density of existing rain stations was assessed based on the standard method of the World Meteorological Organization, while the rationalization analysis of the number and distribution of rain stations used the Kagan-Rodda method and…
The project clean-up Crude Oil Contaminated Soil (COCS) is the work of separating soil contaminated with crude oil and processed by processing technology at the Soil Bioremediation Facilities (SBF) storage facility. COCS of segmentation that has occurred decades ago, this construction work is based on the location and distribution of contamination from the waste (delineation), and the depth of …

Abstract Heavy equipment is a tool used to help and relieve people in doing development work in a project. The use of heavy equipment that is in accordance with the function in project implementation will greatly impact project performance. In addition, it will have an impact on the costs of implementing a construction project. In order for the execution of work to run smoothly, a good hea…
ABSTRACT Population density in Indonesia causes various problems, especially environmental pollution due to daily activities that produce wastewater, such as domestic wastewater. Laundry services are growing rapidly without being accompanied by wastewater treatment. Wastewater from laundry activities can cause environmental pollution if disposed of without wastewater treatment. One simple …
ABSTRACT Daik River in Lingga Regency is one of the rivers prone to floods. To overcome the flooding problem, information is needed about the depth of the flood and the points where the location is prone to flooding. Therefore simulating a water level profile aims to provide information about the depth of floods and flood-prone points on the Daik River in Lingga Regency. Water level profil…
ABSTRACT The high value of side friction on a road will cause a decrease in road performance. The purpose of this study was to determine the level of service at Jalan Jenderal Sudirman, Pekanbaru City during the current Covid-19 Pandemic. The research conducted includes surveys on traffic volume, side friction, road geometric, and light vehicle speed. The research was conducted for 3 days,…
ABSTRACT In addition to peatland fires and the conversion of peatland into plantations, a serious problem is the abrasion of peaty beaches. Abrasion is the result of sediment transport processes parallel to the shoreline (longshore sediment transport). The phenomenon of sediment transport in peat material itself can be said to be unique and complex. Basically, the study of sediment transpo…
ABSTRACT Coal is a source of fuel for electricity generation. Nationally, the demand for coal is 83 million tonnes in 2019. The opening of a new mine in Bangko Tengah Surban Jeriji, Muara Enim, South Sumatra in order to meet national coal consumption needs requires careful planning. The excavated slopes must be made safe and economical, so that mining activities can run smoothly. The purpo…
