Islamic boarding schools are traditional educational institutions that prioritize a religion-based curriculum. The Darul Hikmah Orphans Islamic Boarding School, located in Cot Yang Village, Kuta Barou District, Aceh Besar Regency, Aceh Province, faces the challenge of low levels of entrepreneurial skills in the field of welding and atomizing painting due to the absence of this material in their curriculum. To overcome this, atomizing welding and painting training was carried out at Islamic boarding schools, which aimed to improve students' hard skills in this field. This training is also planned to develop business units, including the establishment of atomizing welding and painting workshops. This atomizing welding and painting entrepreneurship training program is measured by several parameters, with the output being the basic welding technical skills obtained by the students. It is hoped that this program will produce entrepreneurs in atomizing welding and painting workshops that will benefit the environment of the Darul Hikmah Cot Yang Orphan Islamic Boarding School. The training implementation stages include welding and painting theory, occupational health and safety (K3), as well as practice and assistance in basic welding and painting, with the final product being a table. The training material was adopted from teaching welding and painting practices at Syiah Kuala Darussalam University-Aceh. The result of this training is an increase in participants' knowledge in welding and painting, as well as their ability to apply these processes by prioritizing K3 (Occupational Safety and Health).

The purpose of this study is to simulate drop-weight impact tests on hybrid fibre composites made of ramie and Eglass, which are used to make the traditional Acehnese boat wall material for jaloe kayoh. Using composites of ramie-Eglass fiber hybrid in the construction of jaloe kayoh wall material will significantly enhance the strength, durability, and sustainability of traditional Acehnese boats. The simulation was carried out using the finite element method approach using the Abaqus software. Three distinct laminate layer configurations—three layers (GRG), five layers (GRGRG), and six layers (GRGGRG)—with alternating Eglass and ramie fibres make up the test specimens. The ends of the specimen are set with fixed support to ensure boundary conditions, which limit all active structural degrees of freedom on all sides of the specimen. According to simulation results, the specimen with six laminate layers, measuring 12.498 mm, had the largest displacement. The specimen with six laminate layers has the highest stress concentration, measured at 560.6 MPa, while the specimen with three layers has the highest strain concentration, measured at 0.023. Its indicating that the lamina variation can influence the structural performance of the jaloe kayoh material. This research contributes to understanding the potential of ramie-Eglass hybrid fiber composites to enhance the safety and durability of traditional vessels such as jaloe kayoh. The implications of the results can serve as a foundation for the development of superior structural materials in the future.

The efficient utilisation of energy resources is a key concern in industrial operations, particularly within the liquefied natural gas (LNG) sector. During the regasification process, substantial amounts of cold energy are released as LNG transitions from its liquid to gaseous state. This cold energy, often wasted by being discharged into the environment, presents an opportunity for recovery and use in various applications such as cold storage and data centre cooling. While the utilisation of LNG cold energy has been widely explored for specific applications, including data centre cooling, electricity generation, and cryogenic systems, existing studies typically focus on individual technologies rather than a comprehensive optimisation of heat exchanger design for cold energy recovery. Therefore, there remains a significant gap in optimising heat exchanger configurations that maximise cold energy extraction while enabling broader industrial integration. This study addresses that gap by optimising the design of a shell-and-tube heat exchanger to recover cold energy from the LNG regasification process at PT Perta Arun Gas, based on an LNG flow rate of 30 million standard cubic feet per day (MMSCFD). The design optimisation was performed using Aspen Exchanger Design and Rating (Aspen EDR) software. Propane was selected as the secondary fluid for extracting cold energy from LNG due to its exceptionally low-temperature performance (freezing point: -188°C) and proven safety in food-related environments. The shell-and-tube heat exchanger design was optimised by the standards and configurations defined by the TEMA designation. The resulting optimal configuration comprises a shell-and-tube heat exchanger with a tube diameter of 13 mm, a tube length of 2,550 mm, a shell diameter of 162.74 mm, a baffle pitch of 135 mm, 16 baffles, a single tube pass, and 54 tubes. This design achieves a heat transfer rate of 478.5 kW, with an estimated cost of USD 23,895.

The low quality of the thermodynamic process in a gas turbine power plant results in the waste of potential energy and impacts the power plant's efficiency. Analysing the thermodynamic performance of a gas turbine power plant is crucial to evaluating its efficiency in converting fuel energy into useful work. This analysis helps identify opportunities for improvement and optimise the plant's design for better performance by examining the components (e.g., the compressor, combustion chamber, and turbine). This study aims to evaluate the performance of a Gas Turbine Power Plant (GTPP) through thermodynamic analysis considering the variation of cycle loads. The study was conducted based on the field survey data obtained from the GTPP PT PLN Belawan generation implementation unit. The collected operation data was used to perform a thermodynamic analysis by applying the principles of conservation of mass and energy, along with the laws of thermodynamics. The study examined five cycle load variations: 31.7 MW, 34.3 MW, 48.1 MW, 60.7 MW, and 71.7 MW. Results showed a consistent reduction in the gas turbine heat rate as the load increased, with a significant 53.3% drop in heat rate from 34.3 MW to 71.7 MW. Higher cycle loads also correlated with increased turbine and compressor work, with the turbine producing 55.8% more work than the compressor at 71.7 MW. The turbine's thermal efficiency ranged from 40% to 44%, with potential for a 5% efficiency increase.
