Biolubricants are an alternative to lubricants that are clean for machines and renewable. To produce biolubricant is by transesterification. In this study, biolubricant was produced by varying the …
ABSTRACT Activated carbon is known as an adsorbent with a large surface area and micropore volume, which gives it a high adsorption capacity in various applications, particularly in the removal of heavy metals from solutions. However, activated carbon used as an adsorbent in the adsorption process will eventually reach saturation when its adsorption capacity has been fulfilled. This leads to a…
ABSTRACT Bukit Raya District is one of the sub-districts in Pekanbaru City with a population in 2023 of 107,347 people. Population growth and high consumption patterns cause an increase in waste generation which is only transported to Muara Fajar landfill without processing, thus reducing landfill capacity. To overcome this problem, the construction of an Integrated Waste Management Site (TPS…

ABSTRACT The utilization and advancement of wireless technology have reached a significant level of maturity and widespread adoption. One such application is VANET (Vehicular Ad-Hoc Network), a wireless technology integrated into vehicles to enable communication between vehicles (V2V). Challenges arising from the dynamic nature and high-speed mobility of VANETs can be addressed through the uti…
ABSTRACT The magnetic card attendance process has advantages in terms of the speed of recording employee attendance, but the disadvantage of this method in general is that it has the risk of losing or damaging the employee card and can be cheated by leaving the card to commit attendance fraud. Face Recognition Attendance is an attendance method that records the presence of employees through fa…

ABSTRACT Voltage drop in distribution networks can reduce power supply quality and system efficiency. One solution to address this issue is the placement of Distributed Generation (DG) within the distribution network to improve voltage profiles and reduce power losses. This study aims to determine the optimal DG placement using the Particle Swarm Optimization (PSO) method to minimize voltage d…
ABSTRACT Microhydro Power Plant (MHP) is an efficient renewable energy source for remote areas. However, fluctuations in load and water discharge can cause frequency changes that affect system stability. To overcome this problem, this research designs and viiinalyses an Electronic Load Controller (ELC) based on Fuzzy PI Controller to maintain frequency stability in MHP. The Fuzzy PI controller…
ABSTRACT The reliability of the electrical system is crucial for the operation of a building and must comply with PUIL 2011 and the Building Function Feasibility Standard (SLF). Building C of the Faculty of Engineering at Universitas Riau has been in operation for over 20 years without a comprehensive evaluation of its electrical system. This study aims to assess the feasibility of the electri…
ABSTRACT Accidents are one of the problems that often occur on the highway, which can cause huge losses to society. Due to the large losses caused by accidents, special studies are needed in determining accident-prone locations and handling accidents in the future. In this study, a case was taken on the Kuok - Rantau Berangin road section. Secondary data in the form of completed reports obtain…
