Abstract

The concept of green building emerged and has been promoted as a solution to reduce the impact of carbon footprints. It has evolved into an integrated approach to environmentally friendly and sustainable building design, construction, and operation. The objective of this study is to evaluate the implementation of green building principles, assess the level of achievement in meeting green building criteria, and provide recommendations for improvements to help buildings meet the standards set by the Green Building Council Indonesia (GBCI) through its Greenship rating system. This research employed methods including observation, interviews, and measurements, with the results analyzed using a descriptive approach. The assessment of Building X in Bandar Lampung revealed that it scored only 10 out of a maximum of 20 points (equivalent to 45%) for the Indoor Health and Comfort category, and 16 out of a maximum of 36 points (equivalent to 44.4%) for the Energy Efficiency and Conservation category. To improve the green building performance scores, several measures can be undertaken. These include the installation of monitoring instruments for temperature, carbon dioxide, and carbon monoxide levels; indoor air quality assessments; optimization of lighting systems; formation of an energy cluster team; enhanced energy efficiency and conservation strategies; the use of renewable energy sources such as solar panels; and the provision of sub-metering (kWh meters) for ventilation, lighting, and other electrical systems.

Abstract

Suboptimal household waste management remains a problem in various regions. Waste is generally disposed of in landfills (TPA) or burned openly, both of which have negative impacts on the environment. Open burning of waste produces air pollution in the form of carbon monoxide, dioxins, and fine particles that are harmful to health. Therefore, this study aims to design and manufacture a portable, smoke-free waste incinerator as an alternative solution for independent waste management. The research methods used include literature review, design using CAD software, component fabrication, tool assembly, and functional testing. This tool is designed with a combustion system in a furnace with controlled air flow to optimize the combustion process and reduce smoke emissions. The result of this study is a prototype of a portable waste incinerator that is easy to move. Based on the results of functional tests and visual observations, this waste incinerator can burn dry leaves, with the condition that there is still quite a lot of smoke at the beginning of the combustion and the smoke puffs are significantly reduced as the flame grows.

Abstract

This research was conducted as an effort to overcome the problem of domestic waste in Karang Mukti Village, Cipeundeuy Subang. This is to realize community self-sufficiency at the village level in managing waste independently in a better and more efficient way. The initial step, this research focuses on the design and manufacture of a prototype of a waste burner (Incinerator) that can be operated without using fuel (self-burning) and the combustion chamber suhue is designed to reach more than 800oC. With the self-burning system in this incinerator design, it is expected to save operational costs because it will be operated in the village level area. The combustion system utilizes the heat from burning the waste itself (self-burning) with a combustion chamber design lined with heat-resistant walls from materials with good insulating properties, namely refractory bricks. The air flow entering the combustion chamber is generated from natural draft by determining the diameter and height of the chimney. Based on the design results, the Incinerator has a height of 2,000 mm, a length of 1,200 mm and a width of 1,200 mm. The chimney has a diameter of 200 mm and a height of 6,000 mm. Based on the results of domestic waste combustion tests, the lowest suhue in the combustion chamber was 306oC and the highest was 1,100oC. The lowest combustion capacity was 60 kg/hour and the highest was 255 kg/hour. Suhue fluctuations in the combustion chamber and combustion capacity are greatly influenced by the mixture conditions and humidity of the domestic waste fed into the combustion chamber.

Abstract

This research discusses the optimization of Platformer Heater design on PT platforming units.X with additional Sweet Naphtha processing capacity. The main objectives of optimization are toincrease energy efficiency, maintain reaction temperature stability at an optimal level, and overcomelimited heating capacity which has the potential to cause operational problems such as flameimpingement and overfiring. The research method includes Platformer Heater efficiency analysis andheat duty calculations carried out using Microsoft Excel. The operational data analyzed shows that theheating power requirement (Total Required Heater Duty) for the five interheaters has increasedsignificantly after the after conditions compared to the before conditions. The efficiency of eachinterheater is in the range of 70% to 72%, while the efficiency of the Platformer Heater is in the rangeof 70% to 80%. Even though efficiency between devices is relatively stable, this increase in heatingpower requirements indicates an increase in workload or changes in operational conditions that requirethese devices to use more power to continue functioning optimally. For example, interheater 2 requiresheating power of 139,967 Btu/hr in the before condition, which then increases to 221,614 Btu/hr in theafter condition. This confirms that changing conditions affect the amount of energy required for heating,so it is important to consider this in planning and operating the heating system so that efficiency andperformance are maintained. This study also emphasizes the importance of controlling Mean BeamLength and gas emissivity as key factors in increasing heater efficiency. Economic evaluation based onTotal Capital Investment and Operating Cost.

Abstract

The reduction of carbon dioxide emissions, or decarbonization, across all sectors must be carried out seriously. One of these sectors is transportation, through the implementation of an electric vehicle (EV) ecosystem by converting fossil-fuel-powered motorcycles into electric motorcycles. This study aims to design and analyze the performance of a 2 kW mid-drive BLDC motor in an electric motorcycle conversion application. The transition to electric vehicles requires conversion components, such as a BLDC motor. A collaborative research project with an industrial partner, PT X, focuses on the design and modification of a 2 kW mid-drive type BLDC motor. The design process was carried out by varying the gear ratios of 0.68, 0.72, and 1.34 to obtain an electric motorcycle conversion speed suitable for urban road use. Dynotest results indicate that the gear ratio variation of 0.68 provides the best performance using 30T and 20T gears. The maximum speed achieved under this configuration was 78.8 km/h, with a torque of 24.18 Nm at 987 rpm and an output power of 2.8 kW at 1526 rpm.

Abstract

Biodiesel is an alternative fuel derived from renewable sources, one of which is castor oil. In previous studies, the biodiesel production process at the laboratory scale was still carried out using manual heating with an electric stove. In addition, earlier research generally used only single type of catalyst, either KOH or ZnO. To overcome the limitations of manual temperature control, this study applies  temperature control system using  PID autotuning autonics controller to automate temperature reaction. This research apply  further modification by combining KOH  (0.75% w/w and 1% w/w) with ZnO  (0.7% w/w and 0.8% w/w) in the production of biodiesel from castor oil. The research aims to optimize biodiesel yield through the application of a PID-based temperature control system in the transesterification reaction using various catalyst combinations. The resulting biodiesel (B30) from the transesterification process is then tested directly on a diesel engine . The temperature control results using the autonics controller produced PID parameters of P = 4.3, I = 208 s, and D = 36 s. The temperature control system response shows  overshoot of 61 °C, rise time of 16 minutes,  settling time of 24 minutes, and  steady-state error of 0.6 °C. The PID temperature control can replaced manual control by providing a more stable temperature and eliminating reliance on manual adjustments. The highest biodiesel yield was obtained using a combination of 1% w/w KOH and 0.7% w/w ZnO catalysts reaching 91.25%. Interaction between KOH and ZnO tended to reduce yield, indicating that KOH is less suitable when used directly together with ZnO. The biodiesel consumption from the reaction is 270 ml/hour which is lower than that of biosolar at 300 ml/hour.

Abstract

One of the main challenges in processing red palm oil (RPO) was maintaining the stability of active compounds during the drying process. Therefore, appropriate technology was needed to maintain the nutritional quality of red oil. This study aims to evaluate the performance of a laboratory-scale vacuum dryer specifically designed for drying red palm oil. Vacuum drying technology was chosen because it operates at low temperatures and low pressures, thereby minimizing thermal damage to sensitive compounds. Tests were conducted to determine the relationship between temperature changes RPO and the percentage of mass loss of the material against heating time. The heating time was varied to 30, 45, and 60 minutes. Based on the test results, heating time significantly affects the increase in temperature and the decrease in RPO mass. The rise in RPO temperature occurs most rapidly during the first 15 minutes; after that, the RPO temperature remains relatively stable. The results of the mass loss test showed a mass loss of 95.40% at 30 minutes, 94.20% at 45 minutes, and 94.00% at 60 minutes.

Abstract

Oil palm was a leading oil-producing commodity used for both consumer and industrial purposes, while the waste in the form of oil palm fronds has potential as animal feed or compost. Utilizing this waste requires a shredding process to process it into these products. This study aims to determine the effect of blade angle and shaft rotational speed on the chipping results of oil palm fronds in an oil palm chipping machine. The parameters observed include machine chipping capacity, yield, and the percentage of good-sized chips. The study was conducted with three blade angle variations 15°, 25°, and 45° and three shaft rotation speeds 1,200–1,350 rpm, 1,400–1,550 rpm, and 1,600–1,750 rpm. Based on the test results, the chopper shaft rotational speed had a highly significant effect on chipping capacity, while the blade angle had a highly significant effect on both chipping capacity and the percentage of good-sized shreds. The highest chipping capacity was 45,55 kg/h, the highest chipping yield was 98.60%, and the highest percentage of good chip size was 97.88%.

Abstract

The increasing demand for candlenut commodities has driven the need for appropriate mechanization to improve post-harvest processing efficiency, particularly in shell breaking, which is still predominantly performed manually. This condition requires machine innovation that not only increases production capacity but also ensures the structural reliability of the machine frame as the main load-bearing component. This study aims to analyze the structural strength of a candlenut shell crushing machine frame using theoretical calculations and Finite Element Analysis (FEA) through SolidWorks software. The frame is made of AISI 1020 steel with dimensions of 1000 × 785 × 459 mm and a 40 × 40 × 2 mm hollow profile. Loading conditions are defined based on five main load distribution areas. Simulation results show a maximum stress of 12.44 MPa, displacement of 0.024 mm, and a safety factor of 28.25, while theoretical calculations yield 28.05 MPa stress, 1.17 mm displacement, and a safety factor of 12.53. Significant discrepancies arise due to simplifications in analytical assumptions, whereas FEA provides a more realistic structural representation. Nevertheless, both methods confirm that the frame operates within safe limits, although the high safety factor indicates potential overdesign, suggesting the need for structural optimization to improve material efficiency.

Abstract

High-Velocity Oxygen-Fuel (HVOF) coating technology has become a key approach in surface engineering for aircraft-engine components operating under extreme thermal and mechanical conditions. This review maps global research developments, identifies advances in deposition technology, and reveals remaining gaps through a systematic and bibliometric review of 20 Scopus-indexed publications from 2020 to 2025. Using PRISMA-based screening and VOSviewer, the study analyzed publication trends, thematic clusters, and collaboration patterns. The results show a sharp publication increase in 2025 and indicate that 65% of the reviewed studies focused on High-Entropy Alloy and Medium-Entropy Alloy coatings. Major findings include a 40% increase in nano-hardness after post-deposition annealing, successful phase prediction using Scheil-CALPHAD simulation, and the growing role of HVAF as a complementary method with lower oxidation and higher coating density for selected applications. HVOF nevertheless remains the dominant process because of its mature industrial use, dense coatings, and strong adhesion. Future research should integrate computational modeling, real-service degradation studies, and artificial-intelligence-based optimization for aerospace coating design.
