Abstract

Sugarcane (Saccharum officinarum L.) is a raw material that is processed to produce crystal sugar and bioethanol. The process produces sugarcane bagasse. In this study, The liquid-plasma treatment based on microwave plasma in the liquid was used to treat sugarcane bagasse to observe the effect on glucose concentration and gain byproducts. The energy input parameters were varied by 340, 360, and 400 W with irradiation time variations of 1, 3, and 5 minutes. Nelson Somogyi's method was used to determine the percentage of glucose as well as Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscope (SEM), and Image-J software to characterize the side-product of the samples. The results showed that the glucose concentration reduced around 27.6% - 99.2 % after microwave plasma in-liquid treatment at the energy input of 340 Watt and 360 Watt, respectively, with an irradiation time of 5 minutes. The side-product is cellulose nanoparticles which have an average diameter of 92, 106, and 169 nm

Abstract

The coastal area of Pantai Amal, Tarakan City, Indonesia, faces two major environmental challenges: the accumulation of post-harvest seaweed biomass waste and increasing coastal abrasion caused by climate change, both of which threaten environmental quality and the sustainability of local livelihoods. This Community Service Program aimed to develop an integrated community empowerment model by combining appropriate technology, mangrove rehabilitation, and institutional strengthening to address seaweed waste management and climate change adaptation. The program employed a Participatory Action Research (PAR) approach through four iterative stages: Plan, Act, Observe, and Reflect, actively involving community members in planning, implementation, evaluation, and program improvement. The results demonstrated the successful installation of two appropriate technology units, namely a portable solar dryer and a biomass chopper, followed by technical training for 30 community participants, all of whom were able to operate the equipment independently after the training. In addition, 1,000 Rhizophora mangrove seedlings were planted in erosion-prone coastal areas, while a tourism website and official social media platforms managed by the local Tourism Awareness Group (Pokdarwis) were established to strengthen digital promotion and community participation. The novelty of this program lies in the integration of circular economy-based seaweed waste management, ecosystem-based mangrove rehabilitation, and community institutional empowerment into a single community service model. This integrated approach contributes to strengthening local capacity in sustainable resource management, enhancing coastal resilience, and supporting the development of Pantai Amal as a sustainable community-based tourism destination.

Abstract

A standalone hybrid photovoltaic (PV) system integrated with lithium-ion battery storage was designed and evaluated to substitute the auxiliary power demand of the Water Treatment Plant (WTP) at the Malinau Coal-Fired Power Plant (2x3 MW), North Kalimantan, Indonesia. Through PVsyst 8.0 simulations utilizing local irradiance, load profile, and shading parameters, the system achieved an annual solar fraction of 94.3% and a performance ratio (PR) of 67.91%, delivering 120.13 MWh/year of useful energy. Battery round-trip efficiency reached 94.9%, indicating minimal energy loss during storage. These results demonstrate the system's technical viability for replacing fossil-based auxiliary energy in tropical industrial settings. Further implications include cost savings, emission reduction, and enhanced reliability.

Abstract

The use of electric vehicles (EVs) has been rapidly growing, encompassing both fully electric and converted models. A key component of EVs is the battery. This study focused on designing and testing a battery pack for a converted EV named BEATRIX, employing both analytical and experimental methods. The battery, constructed with lithium-ion cells and equipped with a smart management system, achieves a capacity of approximately 72-83V and 19.2Ah. It measures roughly 120mm x 120mm x 330mm and weighs about 5 kg. Testing results indicate that during the discharging process, the voltage and capacity decrease to 75V and 11.5Ah, respectively, while the electric current remains stable at around 4.83A and the temperature is held constant at 32°C. During the charging process, the voltage and capacity increase to 82.2V and 17Ah. Initially, the electric current stabilizes at around 4.38A for 10 to 70 minutes, then gradually decreases to 1.8A at the 100-minute mark, with the temperature remaining steady at 33°C

Abstract

The chassis is the main component of an electric vehicle, serving as a supporting structure for all vehicle components and receiving loads during operation. Therefore, a structural strength analysis is required to ensure the safety of the frame design before the manufacturing process commences. This study aims to design and analyze the strength of a tubular space frame for an electric car using a computational simulation approach based on the finite element method. The frame model is made in three-dimensional geometry and analyzed against static loading with varying rider loads of 46 kg, 56 kg, and 66 kg. The analysis parameters used include Von Mises stress, displacement, and safety factor to evaluate the structural response to loading. The simulation results indicate that at a load of 46 kg, the maximum Von Mises stress is 18.09 MPa, accompanied by a displacement of 0.20 mm and a safety factor of 3.03. At a load of 56 kg, the stress increases to 22.02 MPa with a displacement of 0.24 mm and a safety factor of 2.49. Meanwhile, at a load of 66 kg, a maximum stress of 25.95 MPa was obtained with a displacement of 0.29 mm and a safety factor of 2.11. This maximum stress value is still below the material's yield stress of 207 MPa, so the frame structure is still in a safe condition under the applied load.
