Authors: Sazonov S V 
Published: October 2024

Abstract
An analytical study of the possibility of a two-color light bullet forming during generation of the third harmonics in a graded index waveguide with the focusing Kerr nonlinearity is carried out. It is shown that under conditions of phase and group matching, as well as the absence of group velocity dispersion at the third harmonic frequency, a stable light bullet can be formed under certain restrictions. This applies to the lower limit on the temporal duration of the light bullet and to the upper limit on its power. The most stringent condition is the double restriction on the transverse radius of the light bullet.

Published: October 2024

Abstract
In recent years, energy security has been gaining increasing attention worldwide, leading to a rapid growth in research and literature on the subject. As a result, many definitions regarding energy security have been proposed, reflecting the diverse perspectives and considerations involved in ensuring a secure and sustainable energy supply. There has also been a growing interest in how to measure, which has in turn led to the energy security indicators and indices development. Thus, this paper explores the definition of energy security, as well as its various dimensions and the indices employed to measure it. As a result, the scope of energy security has broadened to encompass contemporary concerns such as the environment, governance, social aspects, and technological efficiency, which were not traditionally given much consideration in the past. As a result, multiple themes have been considered, leading to a more holistic understanding and approach to energy security. This evolution has significant implications for the construction of the energy security index especially in Indonesia, as a more comprehensive set of indicators is now required to offer a comprehensive assessment of energy security within a country and provide valuable insights for energy policymakers.

Published: October 2024

Abstract
The transformation of societies over time has led to a marked shift in energy consumption patterns. In the face of rapid industrial growth and a burgeoning population, Indonesia confronts the multifaceted challenge of achieving a balance among energy trilemma: energy security, economic affordability, and environmental sustainability. This study assesses the feasibility of low-carbon energy systems in Indonesia, evaluating current policies and proposing a roadmap for net-zero emissions. Utilizing the Low Emissions Analysis Platform (LEAP) and the Next Energy Modeling System for Optimization (NEMO), the study explores multiple scenarios—namely, Business-as-Usual (BAU), Carbon Capture and Storage Mitigation (CCSM), and New and Renewable Energy Mitigation (NREM). Of these, the NREM scenario, emphasizing the integration of innovative and renewable energy sources, achieves the most substantial reduction in greenhouse gas emissions while maintaining economic viability. This strategy advocates for the comprehensive adoption of new and renewable energy, aiming to approximate zero emissions by 2060. The peak direct cost of production for this scenario is estimated at $270.8 billion. However, each scenario presents its own set of technological, economic, and policy-related challenges, necessitating strategic solutions for a successful transition to sustainable energy systems.

Abstract
Processing radioactive waste remains a formidable task in utilizing radioactive materials due to their inherent toxicity and carcinogenic nature, necessitating treatment before safe release into the environment. Among the methods employed for radioactive waste treatment, adsorption stands out, with considerable attention focused on an emerging adsorbent named [Cu3(C6H3(COO)3)2(H2O)3]n or Hong Kong University of Science and Technology-1 (HKUST-1), renowned for its distinctive properties. HKUST-1, being a porous material, holds promise as an effective agent for radioactive waste adsorption. In this investigation, HKUST-1 was synthesized via the solvothermal technique at 100°C, and its resilience was evaluated under electron beam irradiation at doses ranging from 50 to 150 kGy. Characterization techniques involving SEM, XRD, and adsorption tests were conducted to assess any alterations in HKUST-1’s attributes pre- and post-irradiation. Results revealed modifications in HKUST- 1’s characteristics following electron beam exposure, notably a decline in crystal adsorption quality within the 50 to 125 kGy dose range, indicating amorphization. Additionally, irradiation at 50 and 150 kGy demonstrated a potential for crystallization, thereby augmenting adsorption quality. Remarkably, the most favorable adsorption performance was observed at a 150 kGy irradiation dose, showcasing an average adsorbed gas volume of 332.05 cm3/g, a surface area of 947.747 m2/g, and a pore volume of 0.5586 cm3/g.

Abstract
The 99Mo/99mTc generator is a chromatography column system that can be eluted to obtain technetium-99m (99mTc) for nuclear medicine applications in the hospital. Mesoporous titania is developed for the Mo adsorbent of a 99Mo/99mTc generator column employing low specific activity 99Mo produced by nuclear reactor irradiation of natural molybdenum. A symmetric triblock copolymer of P123 was used as a template to create mesoporous titania using the sol-gel process.. The molar ratio of the reactant (titanium tetraisopropoxide (TTIP) and titanium chloride (TiCl4)) was applied with ratios 1:1 and 3:2. Then, the different temperature calcination also was implied at 450 °C and 550 °C. The resulting mesoporous titania was studied utilizing thermal gravimetry analysis (TGA), nitrogen adsorption-desorption, and characterization analysis of X-ray diffraction. Furthermore, the Mo adsorption test was conducted by batch method. The highest molybdenum adsorption capacity of mesoporous titania samples is 34.62 mg Mo g−1 adsorbent. Mesoporous titania has the potential as a novel adsorbent for the 99Mo/99mTc generator column.

Abstract
This study investigated the application of amidoximated bacterial cellulose (AMO-BC) film for lead (Pb) adsorption from aqueous solutions. In our previous study, bacterial cellulose has been successfully modified through amidoximation to enhance its metal adsorption capacity. In order to modify the bacterial cellulose (BC) film, acrylonitrile was grafted onto it initiated by an electron beam to create BC-grafted-polyacrylonitrile (BC-g-PAN). After that, amidoximated bacterial cellulose (AMO-BC) was generated when BC-g-PAN reacted with hydroxylamine hydrochloride to add amidoxime functional groups to the cellulose backbone. Then, AMO-BC before and after lead adsorption was characterized using Fourier-transform infrared spectroscopy (FTIR). The adsorption capacity of AMO-BC for lead ions was evaluated through batch adsorption experiments with the initial lead concentration of 200 mgL−1 and an adsorbent dose of 20 mg, on pH 6 for two hours of the adsorption process. The results showed that AMO-BC exhibited higher lead adsorption capacity than pristine bacterial cellulose i.e., 44.56 and 50.96 mg/gram for BC and AMO-BC films, respectively.

Abstract
Stirring the electrolyte meanwhile electrodeposition process is running may influence the properties of the forming films. In this work, the electrodeposition of copper (Cu) over aluminium (Al) alloy was performed. Subsequently, the electrodeposition of nickel (Ni) onto the formed Cu layer was conducted. In order to enhance the films properties, some various stirring speeds then are implied on the plating solution of the Ni electrodeposition process. The synthesized of Ni films were analysed by means of both X-ray diffraction (XRD) and a potentiostat equipment. The sample made shows different physical properties before and after electrodeposition based on sample weighed to examine the deposition rate. XRD patterns confirmed that all samples have a face-centered cubic (fcc) crystal structures with a space group of Fm-3m. Stirring speed play an important role of an inverse relationship with deposition rate, crystallite size, lattice strain, and corrosion rate. The sample that was made using the highest stirring speed yield a better corrosion resistance at around 0.239 mmpy due to less lattice strain.

Abstract
Gold nanoparticles (AuNPs) have attracted much attention as one of the most effective agents with high catalytic activities for radical scavenging reactions. Many studies have investigated its antioxidant activity using various in vitro methods and have shown promising scavenging action. In this research, we demonstrated the synthesis of Au nanofilms (AuNFs) by cyclic voltammetry technique and evaluated for their antioxidant activity. The application of a range of voltage levels was utilized in the synthesis of AuNFs, and their antioxidant potential was subsequently assessed through in vitro 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. All AuNFs exhibited antioxidant activity which increased as the upper potential was reduced from 1,5 V to 0,75 V. The antioxidant activity of AuNFs was shown to increase gradually with longer incubation times before the DPPH assay, indicating a significant impact on their performance. The obtained inhibition percentage was ranging from 8,26% to 22,91%. The highest antioxidant activity could be achieved by synthesizing AuNFs using 0,75V of upper potential and incubating it for 90 minutes prior to DPPH assay. The variations in the applied potential influenced the morphological characteristics of AuNFs, leading to increased surface area, while the duration of incubation was found to enhance the efficacy of the scavenging reaction between the AuNFs and DPPH. In conclusion, this cyclic voltammetry technique was shown to successfully synthesize AuNFs with significant antioxidant activity.

Abstract
Chitosan is natural polymer with abundant availability and unique characteristics. The purpose of this study was to investigate the effects of various isolation methods on chitosan properties. Chitosan was obtained by isolation method using oyster pearl shell (Pinctada maxima sp.). The parameters of the deacetylation process are the comparison of heating method with microwave method and the comparison of microwave power. Chitosan was characterized for degree of deacetylation (DD) and functional groups by FTIR, and viscosity by Brookfield viscometer. The microwave method was faster than the heating method. Then, the larger mass of shell and %NaOH produced a higher DD of 89.75%. However, the use of 60g mass and 60% NaOH resulted in an already high DD of 81.96%. Furthermore, variation microwave power showed the highest DD at high power. FTIR spectrum analysis showed the appearance of chitosan functional groups, OH and NH2 groups. The viscosity value decreased as the microwave power increased. Based on this study, different isolation methods affect the quality of chitosan. However, it’s necessary to conduct more detailed research related to changes in chemical structure. Therefore, oyster shells can produce chitosan as a source of natural polymers with different characteristics.

Abstract
This paper presents the utilization of active noise canceling (ANC) technology using an embedded system for a sound insulation box. The ANC system for the insulation box is designed to replace conventional heavyweight passive sound absorber systems. A feedback filtered-x least mean square (FxLMS) algorithm is utilized to create the opposing-noise signal to counteract the incoming noise entering the box, so that reducing the noise level inside the box. In our previous work, we delved into a similar topic of using ANC for a sound insulation box, but the prior system had limited performance due to its inability to operate in real time. In this study, the FxLMS algorithm is implemented on an ARM Cortex-based microcontroller development board. A feedback structure is utilized, with an error microphone positioned in the middle of the box The ANC system’s capability was evaluated for pure tone noise in the frequency range of 63 Hz to 630 Hz. The experimental findings indicate that the ANC system has the capability to cut back the noise level up to 4 dB for some frequencies.
