ABSTRACT Micro, Small, and Medium Enterprises (UMKM) in the culinary sector face challenges in production efficiency due to the limitations of the equipment they use. Many business owners still rely on manual methods or simple machines that are unhygienic, inefficient, and difficult to clean. To address these issues, this final project aims to modify a manual meat grinder into a motorized syst…
ABSTRACT This study aims to utilize extracted Spent Bleaching Earth (SBE) waste as an additive material in the production of clay bricks. SBE waste is a by-product of the palm oil bleaching process, which is abundantly available and has the potential to cause environmental pollution if not properly managed. The variations of SBE content used in this research were 0%, 30%, 40%, 50%, and 60% of …
ABSTRACT Kuantan Singingi Regency, Riau Province, is an area that still lacks specialized health facilities for mothers and children. This condition has resulted in suboptimal maternal and neonatal health services, as well as a high number of referrals to other areas.

ABSTRACT Indonesia has abundant solar energy potential, making Solar Power Plants (PLTS) a strategic alternative to support the national energy supply. This study aims to design a Rooftop On-Grid Solar Power System (PLTS) at the Faculty of Engineering, Riau University, as well as analyze its investment feasibility. There are seven buildings at the Faculty of Engineering, Riau University, that …
ABSTRACT The reliability of the radial feeder KP02–PK Kampung Aie remains low, as indicated by the high frequency of power outages experienced by customers under existing conditions. This study evaluates network maneuvering by utilizing alternative power supplies from PLTD Sibigo and KP03–PK Alafan as parallel paths to limit the affected area and outage duration. Two main approaches are em…
ABSTRACT The management of accreditation supporting documents in the Informatics Engineering Study Program at the University of Riau still relies on Google Drive. This approach presents several issues, including ineffective document search due to the lack of multi-word query support, the absence of progress monitoring for required documents, and the repeated uploading of identical documents ac…

The plant is planned to be built in North Bontang District, Bontang City, East Kalimantan Province based on proximity to raw material sources and supporting industrial facilities such as ports, distribution networks, and energy and …
ABSTRACT Dimethyl Ether (DME) is a simple ether compound used as a raw material in industry and as a fuel. DME is a colorless, odorless gas that is soluble in water and oil. It is non-carcinogenic, non-teratogenic, non-mutagenic, and non-toxic. It exhibits environmentally friendly properties because its combustion does not produce sulfuric acid (SOx) and smoke, and produces very low levels of …
ABSTRACT Dimethyl ether (DME) is an organic compound with the chemical formula CH3OCH3 that functions as a potential fuel substitute for natural gas. DME has physical properties similar to propane and n-butane, making it suitable as a substitute for LPG. DME production is focused on meeting market demand for LPG substitutes and reducing LPG imports in Indonesia. The DME market in Indonesia is …
ABSTRACT Fatty alcohol is a high alcohol compound (aliphatic class) that has a chain length between C8 and C32 that can be produced from animal fat or vegetable oil. Fatty alcohols are generally used as surfactants, emulsifiers, and emollients, for example in detergent, cosmetic, and skincare products. Indonesia has continued to import fatty alcohol for the past five years with an average annu…
ABSTRACT Biodiesel is a sustainable fuel solution to address the scarcity of fossil fuels. It is produced from renewable resources such as vegetable oils, animal fats, and waste cooking oil or Waste Vegetable Oil (WVO). Biodiesel derived from WVO is highly competitive as it utilizes waste, making it more economical and environmentally friendly compared to fossil-based fuels. A biodiesel plant …
