ABSTRACT This study aims to analyze the effect of using acetone, metanol, and water as working fluids in heat pipes on the performance of a Photovoltaic/Thermal (PV/T) system. A PV/T system integrates photovoltaic panels to generate electricity and thermal collectors for water heating, thereby enabling more efficient solar energy utilization. The heat pipe plays a crucial role in enhancing…
ABSTRACT Unmanned Aerial Vehicle (UAV) is an unmanned aerial robot that is now a national sport in the First Person View (FPV) category. Carbon fibre, as a popular FPV frame material in the aerospace industry, has the disadvantage of being brittle and not environmentally friendly as it is difficult to decompose. As an alternative, synthetic and natural fibre-based composite materials, such as …
ABSTRACT The use of conventional plastic causes serious environmental pollution due to its long degradation time and difficulty in recycling. Therefore, an alternative to environmentally friendly and easily biodegradable plastic materials is needed. One of the biodegradable materials that can be found in nature is starch from durian seeds and cellulose from pineapple leaf fibers. This research…
ABSTRACT This study aims to analyze the kinematics of a laboratory-scale excavator arm using manual calculation methods. The analysis includes determining the Degrees of Freedom (DOF), position, velocity, and acceleration of the boom, arm, and bucket mechanisms. The results show that the excavator arm mechanism has 3 DOF. In position analysis, the widest range is found at Point H for the boo…
ABSTRACT This study analyzes the effectiveness of Kernel Crushing Plant machines at PT. Wilmar Nabati Dumai using the Overall Equipment Effectiveness (OEE) method. This study also determines the machine maintenance interval based on Mean Time To Failure (MTTF) and Mean Time To Repair (MTTR). The results of the OEE analysis show that the machine effectiveness value is still below the world-clas…
ABSTRACT Vertical motion hydraulic pipe bending equipment or also called edge bending uses the rotary draw bender method, with a hydraulic jack rod pushing and rotating the die so that it pulls the pipe until it bends following the path of the rotating die. This equipment is designed for continuous laboratory scale research. Bent pipes often experience deformation in the form of shrinkage at t…

ABSTRACT This study aims to implement a Virtual Private Network (VPN) using Wireguard as a security solution on the Sahabat Net network in Perawang City. Sahabat Net, an RT/RW Net business, provides internet services with connections between users around Perawang, but currently does not have adequate network security. The use of Wireguard VPN is expected to provide better data security with pr…
ABSTRACT Most of Indonesia's territory is water, so sea transportation plays an important role in people's lives. This transportation is a ship. Ships function as a service for transporting goods and passengers. In addition, ships are also often used in industry, mining and trade. This has resulted in increasing ship production every year. Along with the increase in ship production, the need f…
ABSTRACT Pentaerythritol is a chemical used as a resin in the explosives industry, paint industry, lubricants, and other sectors. The production of pentaerythritol in this factory utilizes the ERCROS process. The plant is designed to operate for 330 days a year, continuously working 24 hours a day with a capacity of 20,000 tons per year, and will be located in Serang, Banten. The chosen compan…
ABSTRACT An increase in occupational diseases, particularly Carpal Tunnel Syndrome, is increasingly occurring in workers who perform repetitive movements and prolonged hand use. Although the prevalence of carpal tunnel syndrome in the world is quite high, the related data in Indonesia is still unclear, indicating low public awareness of this disease. For this reason, a web-based expert system …
ABSTRACT In the Radio over Fiber (RoF) system, a reduction in received radio frequency (RF) power often occurs due to chromatic dispersion in optical fibers, known as dispersion power fading (DPF). To address this issue, a new technique called Unbalance Sideband Modulation (USM) is proposed. USM is implemented by modulating the optical carrier signal using an RF signal with a single-drive Mach…
ABSTRACT This study aims to determine the optimum tilt angle and orientation of photovoltaic panels to increase the efficiency of solar power generation (PLTS) in Pekanbaru, which has abundant solar energy potential. Experiments were conducted using four monocrystalline PV panels with a capacity of 20 WP with tilt angles of 10°, 15°, 20°, and 25° and orientations of north, east, south,…
Fishermen's perceptions of senangin fishing efforts and their relationship with the scale of fishing efforts in Bagan Barat Village seen from traditional, post-traditional, and commercial fishermen.
