ABSTRACK Inclusive education, particularly in the learning of Hijaiyah letters (Arabic alphabet), remains a significant challenge for deaf students. Conventional media often fails to bridge this communication barrier, a problem exacerbated by the difficulty of distinguishing between several very similar hand gestures, a real issue observed at SLB Panam Mulia Pekanbaru. To address this gap …
ABSTRACT The gaming industry has grown rapidly, and one of the key elements in a game is the non-playable character (NPC). Easily predictable NPC behavior often reduces player engagement and satisfaction. Static or unresponsive NPCs tend to create monotonous and less challenging gameplay experiences, ultimately lowering game quality and player interest. This study applies Deep Reinforcement Le…
ABSTRACT This study aims to design and develop a store security system based on the Internet of Things (IoT) to enhance monitoring effectiveness and real-time store security. The system utilizes an ESP32-CAM as the main controller, integrated with a PIR sensor, two servo motors, and a Telegram Bot as a notification medium. It is designed to detect motion, capture images, and display livest…
ABSTRACT The increase in population and industrial activity in the Payung Sekaki District of Pekanbaru City has had an impact on the increase in waste entering the Muara Fajar landfill. According to Presidential Regulation No. 97 of 2017, 30% of waste must be managed at the source, and the limited capacity of each subdistrict to reduce waste is one of the main problems that is predicted to con…
ABSTRACT The high accumulation of soybean seed coat and tofu dregs waste contributes to environmental problems, therefore, an effective and eco-friendly waste management alternative is needed. One potential solution is the utilization of Black Soldier Fly (BSF) larvae. This study aimed to evaluate the effect of fermented feed variations of soybean seed coat and tofu dregs on the performanc…
ABSTRACT The activity of loading fresh fruit bunches (FFB) in PT XYZ is still carried out manually using simple tools such as a T-hook or tojok. Non-ergonomic working postures and heavy physical workload have the potential to cause Musculoskeletal Disorders (MSDs). This study aims to analyze the level of postural risk using the Rapid Upper Limb Assessment (RULA) method assisted by the Ergo…
ABSTRACT The waste management issue in Binawidya District remains a challenge due to low public awareness of paying waste service retribution fees. This condition has the potential to hinder the sustainability of an effective waste management system. This study aims to analyze the community’s Willingness To Pay (WTP) and Ability To Pay (ATP), as well as identify the factors that influenc…
ABSTRACT Storage tanks are storage containers frequently used in various industries such as petrochemical, refining, petroleum, and others. The reliability of storage tanks is crucial because structural failures can result in serious consequences. The purpose of this study is to evaluate the operational feasibility of tanks with shell distortion defects in the form of arbitrary out of roundnes…
ABSTRACT A construction project has specific objectives that must be met, namely on-time, onbudget, and on-quality, as well as safety in the construction process. These objectives will be met if there is good management, one of which is project time management. This study aims to evaluate the application of Project Time Management (PTM) in construction projects carried out by contractors i…
ABSTRACT The behavior of a building during an earthquake is highly dependent on several parameters such as shape, size, and overall geometry. These parameters will determine the overall capacity of the building, especially seismic parameters. The ratio of vertical aspect (H/L or H/B) and aspect ratio horizontal ratio (L max /L min) affects the efficiency and stability of the structure in w…
ABSTRACT The Rokan Kiri sub-watershed is one of the sub-watersheds of the Rokan watershed. On February 26-27, 2025, flooding occurred due to the overflowing of the Rokan Kiri River. To reduce the risk of flooding, water structures are needed whose planning requires accurate design flood discharge to produce reliable, safe, and economical water structures with hydrological analysis. One app…
ABSTRACT Pangkalan Kerinci District is an area with a high level of flood risk caused by intense rainfall, overflow of the Kampar River, and land use changes due to industrial and residential activities. Based on a survey conducted by PT Tri Karsa (2022), there were 20 flood points in Pangkalan Kerinci Kota Village and 4 flood points in Pangkalan Kerinci Barat Village. The preparation of t…
ABSTRACT The ground wire serves as a protective phase wire from lightning strikes, problems arise when lightning strikes the ground wire. So that the lightning current flows in the ground wire, thus an increase in voltage occurs in the tower. The technology that has been developed by ITB and PT. PLN Persero is the I-GSW system functions to protect the transmission tower from lightning currents…
The condition of people living in peatland areas makes it difficult to get clean water for daily needs and they have to buy clean water to meet their needs. Economic limitations make people in peatland areas use clean water for food, drinks and washing so that they are unable to use clean water to be mixed with concrete. People living in peatland areas only have another option to use peat water…
Biodiesel is an alternative fuel derived from renewable resources such as vegetable oils and animal fats. Its quality is highly influenced by the composition of its fatty acids, which include saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA). A high PUFA content can reduce the oxidative stability of biodiesel and accelerate degradation d…
