The role of mesoporous solid acid aluminosilicate in the oleic acid deoxygenation was elucidated using ZSM-5 and Al-MCM-41 impregnated with Ni. The mesoporous supports were synthesized using a similar initial Si/Al ratio but employing different templates to vary the mesopores. ZSM-5_T produced interparticle mesopores when using TPAOH (tetrapropylammonium hydroxide) as a template. Meanwhile, ZSM-5_S with a well-defined intraparticle mesoporous channel was formed using a silicalite template. Al-MCM-41 synthesized without a template produced one-dimensional highly ordered mesoporous channels. The arrangement of mesoporosity in aluminosilicate determined the mechanistic pathway of oleic acid conversion into hydrocarbon. Oleic acid underwent primary thermal cracking into carboxylic acid before progressing into the subsequent decarbonylation reaction. The diesel hydrocarbon yield was enhanced following the order of Al-MCM-41>ZSM-5_S>ZSM-5_T>blank reaction. Large intraparticle mesoporosity produced long-chain carboxylic acid from catalytic cracking of oleic acid, which was subsequently deoxygenated into long-chain hydrocarbons.

Recent research has reported on the extraction and synthesis of silica gels from a waste glass of chemicals. This study aims to optimize silica gel synthesized from chemical glass waste as heavy metal adsorbent Cu2+. Silica gel adsorbent has been successfully synthesized by reacting silica from chemical glass waste and sodium hydroxide (NaOH) by a fusion reaction and sol–gel process. Synthesized silica gel has an amorphous diffractogram at 2θ 20–30°, a purity of 75.63 %, a surface area of 297.08 m2/g, and a pore radius of 15.74 nm. The adsorption formulation was optimized using Design Box–Behnken and optimum conditions were obtained at adsorbent doses close to 3.5 g, initial concentration 50–100 ppm, contact time 10 min, and pH 9. Adsorption Isotherm Langmuir, Freundlich, Temkin, and Dubinin–Raduskevich were investigated to determine the mechanism of adsorption. Adsorption data show that the adsorption is well-fitted to the Langmuir isotherm model. The results of SEM–EDX characterization showed that the surface morphology of silica gel showed a spherical and irregular surface then after adsorption cu metal was distributed on the surface of the silica gel. Based on all the results of the study it can be indicated that silica gel synthesized from chemical glass bottle waste can be applied as adsorbent Cu2+.

Autonomous electric vehicles (EVs) need to recognize the surrounding environment through mapping. The mapping provides directions for driving in new locations and uncharted areas. However, few studies have discussed the mapping of unknown outdoor areas using light detection and ranging (LiDAR) with simultaneous localization and mapping (SLAM). LiDAR can reduce the limitations of GPS, which cannot track the current location, and it covers a limited area. Hence, this study used the Hector SLAM algorithm, which maps based on the data generated by LiDAR sensors. This study was conducted at the Universitas Sriwijaya using two routes: the Palembang and Inderalaya campuses. A comparison is made with the map on Google Maps to determine the accuracy of the algorithm. The route of the Palembang campus was divided into four points: A-B-C-D; route AB exhibits the highest accuracy of 85.7%. In contrast, the route of the Inderalaya campus was established by adding routes with buildings closer to the road. A marker point was allocated on the route: A-B-C-D-E; route CE exhibits the highest accuracy of 83.6%. Overall, this study shows that the Hector SLAM algorithm and LiDAR can be used to map the unknown environment of autonomous EVs.

Investigations on kidungan, a form of traditional Javanese poetry, have been gaining momentum. However, there is a lack of comprehensive reports exploring the value of Javanese cultural wisdom in relation to social dimensions, symbolic politics, and educational values as reflected in kidungan. This study aims to address this gap by delving into the social dimension, symbolic politics, and educational value embedded in traditional Javanese poetry, specifically in kidungan ludruk. The research data for this study is sourced from ludruk performances broadcasted by Radi Republik Indonesia (RRI) East Java and expert interviews. The data collected were then analyzed using qualitative descriptive techniques, employing an ethnolinguistic research approach. The findings of this study revealed that ludruk kidungan serves as a social representation of traditional society, encompassing various aspects of social dimensions, symbolic politics, and educational values. An important implication of this study is that kidungan has the potential to contribute to the development of sustainable knowledge, particularly in the fields of culture, politics, and education.

In this study, the anionic and cationic gels were synthesized separately using copolymerization between N-isopropylacrylamide (NIPAM) and acrylic acid or chitosan through a polymerization reaction using N,N'-methylenebisacrylamide (MBAA) as a cross-linker with various monomer concentrations and synthesis temperature. The anionic and cationic gels were blended to minimize inter-intra particle association and to improve the adsorption ability. The FTIR analysis found that the synthesis of the NIPAM-co-acrylic acid and NIPAM-co-chitosan gels was successfully carried out, indicating no presence of a vinyl group in the functional group. The result showed that the ion adsorption amount of Pb2+ ions blending gels increased significantly, almost twice compared to the adsorption before blending. The adsorption amount of Pb2+ ions increased with increasing the gel synthesis temperature. The adsorption amount follows the order of Pb2+ > Fe2+ > Ni2+. The adsorption amount of Pb2+ tends to decrease with increasing sedimentation volume. The higher the synthesis temperature, the larger the porous diameter formed. These results demonstrate that blending gel of NIPAM-co-chitosan and NIPAM-co-acrylic acid is a feasible alternative for removing heavy metal ions owing to its good adsorption performance.

The results provide a new method for producing AgNPs with excellent antibacterial activity.

Industrial activities generate a significant problem in the form of dye waste, which contributes to environmental pollution, particularly water pollution. Improper disposal of untreated dye waste can lead to detrimental effects on ecosystems, the environment, and living organisms. To mitigate these issues, various methods such as biological treatment, chemical oxidation, flocculation-coagulation, and adsorption are employed to remove or reduce dye and other pollutants from wastewater. Among these methods, adsorption has proven to be a cost-effective and straightforward approach for the removal of pollutants, particularly dye waste, from water. While activated carbon is commonly used as an adsorbent in the industry, it has drawbacks such as high cost and difficulty in regeneration, especially in the form of powdered activated carbon. Remazol Brilliant Blue R (RBBR) is a specific dye extensively utilized in the textile industry. It belongs to the category of reactive dyes that are challenging to degrade and pose toxicity risks to aquatic ecosystems. The use of bio-adsorbents in dye removal offers advantages such as low cost, easy availability and production, as well as the ability to be regenerated. When utilizing activated carbon derived from bio-materials, RBBR removal rates of 88.51% have been achieved. The agricultural waste powder as an adsorbent yields a removal rate of 90.82%, while non-conventional bio-adsorbents exhibit a removal rate of 90.50%. This review aims to compile information on bio-adsorbents and their effectiveness in adsorbing RBBR, shedding light on their potential for addressing dye waste pollution.

Quantitative Structure-Activity Relationship (QSAR) is a powerful tool for investigating the correlation between the chemical and biological properties of molecules. It employs mathematical and statistical modeling techniques that focus on molecular descriptors, which represent various characteristics of the molecules. However, the extensive use of descriptors in QSAR modeling introduces complexities in data analysis and computation. To address these challenges, data preprocessing techniques, such as data reduction and feature selection, are critical for directing the inputs of statistical models. Feature selection plays a crucial role in improving the accuracy and efficiency of machine learning algorithms by identifying relevant features that significantly influence the target response. In this study, a comprehensive comparison of preprocessing methods in QSAR modeling is carried out. The methods under investigation include filtering through Recursive Feature Elimination (RFE) and wrapping methods such as Forward Selection (FS), Backward Elimination (BE), and Stepwise Selection (SS). To evaluate the effectiveness of these preprocessing methods, both linear regression and nonlinear regression models were utilized. The research findings reveal the usefulness of feature selection methods in reducing the number of descriptors required for the accurate assessment of anti-cathepsin activity. Remarkably, the FS, BE, and SS methods, particularly when coupled with nonlinear regression models, exhibit promising performance relating to R-squared scores. This research emphasizes the significance of data preprocessing, particularly feature selection, in QSAR modeling. The comparative analysis of different preprocessing methods provides a valuable understanding of their effectiveness in reducing descriptor complexity and improving model performance. These findings contribute to the improvement of QSAR modeling techniques, supporting accurate predictions of anti-cathepsin activity and enabling the exploration of structure-activity relationships in drug discovery and design.

The anti-corrosive properties of Gambir extract on SS-316 stainless steel were studied. It was found that the addition of Gambir extract in the HCl solution decreased the SS-316 average corrosion current density (I_corr) compared to the blank solution. The response surface methodology plot showed that I_corr increased with increasing HCl concentration and contact time, but decreased with higher concentrations of Gambir extract, indicating its effectiveness in inhibiting corrosion even under harsher conditions. Surface characterization confirmed the formation of this protective layer, while FTIR analysis identified the main functional groups involved in the metal-inhibitor interaction.

The catalytic conversion of Reutealis trisperma oil was carried out over a Al-MCM-41 based catalyst with different Si/Al ratio with no added hydrogen to examine the possibility of the direct production of hydrocarbons in the ranges of jet fuel. In a semi-batch reactor, RTO was combined with 3 % catalyst and heated to 350 °C for 4h. The blank reaction shows the lowest conversion and liquid yield, with values of 39.65 % and 8.74 %, respectively. In contrast, the highest conversion was achieved using the Al-MCM-41 (30) catalyst, and the conversion decreases as the Si/Al ratio of the Al-MCM-41 catalyst increases. Indeed, the mesoporous structure enabled extensive bio-oil diffusion and adsorption, further increasing catalytic conversion. The Al-MCM-41 (30) shows the great performance in catalytic conversion of RTO to hydrocarbon and aromatic chain hydrocarbon. The Al-MCM-41 (30) catalyst resulted in a composition of 41.26 % paraffin, 6.78 % olefin, 21.77 % arenes, and 11.44 % cycloparaffin. This composition is comparable to JP-8 and Jet-A fuels, satisfying the ASTM D7566 standard for aircraft turbine fuel containing synthetic hydrocarbons. The acid site and pore size on the support material influenced the interaction of bio-oil molecules and catalyst which increasing the rate of reactant/product diffusion and improve the jet-fuel production. The obtained results are promising for the use of non-edible RTO and kaolin-derived catalysts in the production of sustainable alternative jet fuels. This approach offers competitive costs and significant environmental and social benefits.

The technical challenge in constructing the electron source (ES) lies in the joining of metal and ceramic tubes. Furthermore, there is a lack of available technical comparison data for the output performance between the diode and triode ES under the same experimental conditions. The research aim is to describe a simple technique for constructing the diode and triode ES for an electron beam machine (EBM) of 300 keV/20 mA, and to investigate their output characteristics. The method used is to make a flange for mounting the Tungsten filament, Pierce electrodes, and heat shield. Two or three electrodes of the NEC (National Electric Corporation) accelerator tube are removed before the flange is united into the NEC tube, becoming the ES. The ES‘s are investigated in terms of their electron beam profiles and beam current output for the variation of the extraction electrode voltage as well as the focusing electrode voltage. The experimental results show that for the triode ES, the focusing electrode voltage greatly affects the shape of the electron beam profile up to 3 kV. However, for the diode ES, the shape of the electron beam profile is slightly affected by the extraction electrode voltage. The beam current output increases rapidly with the increase of the extraction electrode voltage up to 2.5 kV. Above this voltage, the beam current slowly increases, and it tends to reach saturation. The diode ES provides a higher electron beam current output than the triode ES output, but the triode ES provides a better shape of the electron beam profile. The constructed ES can provide the electron beam current of 40 mA at the filament current of 18 A.

The Indonesian Competition Commission (ICC) in 2022 has compiled a study on Alleged Control of Business Use Rights in the Palm Oil Plantation Sub-Sector that Can Result in Monopolistic Practices or Unfair Business Competition with the conclusion that the results of the analysis conducted on secondary data regarding companies engaged in the palm oil and cooking oil agribusiness system, the conclusion is obtained that leads to the alleged potential violation of Article 17 of Law Number 5 of 1999 concerning Prohibition of Monopolistic Practices and Unfair Business Competition. The palm oil agribusiness system is closely related to the palm-based cooking oil industry system. However, the two systems each have a structural pattern that has a very high level of complexity. The Palm Oil industry has a market structure of oligopoly in the downstream, and oligopsony in the upstream. This condition allows the dominant company to become a price maker at all stages of the palm oil industry supply chain. Oligopoly and oligopsony conditions can cause deadweight loss for smallholder oil palm farmers (pressure on FFB prices), consumers (palm oil prices), and even the government

Nanocrystalline cellulose (NCs) was successfully isolated from pepper biowaste using lactic acid hydrolysis and employed as filler in seaweed biocomposite. Optimization of hydrolysis parameters by employing response surface methodology (RSM) generates 75.50 % NCs with 76.68 % crystallinity at 6.31 M lactic acid, 3.02 h and 85.86 °C. The ANOVA analysis indicates hydrolysis efficiency requires precise temperature control and lactic acid concentration to obtain high crystalline cellulose at high production yield. The NCs displayed rod-shaped morphology with 29.65 ± 3 nm diameter and 335.19 ± 10 nm length, with a negative zeta potential and higher thermal stability than the cellulose. NCs addition as filler in seaweed biofilm improved the tensile strength but reduced the elongation at break. The biofilm exhibits excellent properties in reducing water adsorption, solubility, and water permeability by increasing nanocellulose filler.

The utilization of blockchain technology in the fishing industry has been extensively studied and implemented to address issues such as illegal fishing and carbon emissions control. However, integrating blockchain with the vast amounts of data in the fishing supply chain poses significant challenges. Challenges include managing extensive data such as photos or videos for product traceability throughout their lifecycle, compounded by the growing complexity of cross-border trade and market expansion. Additionally, blockchain's storage capacity limitations present hurdles in fully accommodating and comprehensively storing detailed supply data from a complex and expanding supply chain.While solutions like the Interplanetary File System (IPFS) have been explored for large data storage on the blockchain, this paper proposes a directly integrated blockchain solution tailored for the challenges of fishing with big data. We introduce a novel big data design that preserves blockchain's anonymity and immutability features, addressing storage limitations while maintaining the architecture's purpose. Furthermore, our proposal integrates product supply chain traceability with carbon footprint tracking, enabling comprehensive assessment based on quality, sustainability, and carbon footprint criteria.Despite the proposed solution needing to be tested in real-life situations, we conducted rigorous testing through simulation, white-box evaluation, and complexity analysis. The results demonstrate the potential of our solution to address challenges faced in fisheries supply chains, providing valuable insights for future practical implementation and validation efforts.

Dolomite as the catalyst for pyrolysis of waste cooking oil (WCO) was investigated to produce hydrocarbon fuels. Optimization of pyrolysis parameters i.e. time, temperature and catalysts loading, achieved high selectivity of WCO to diesel hydrocarbon, compared to thermal pyrolysis that produced mainly carboxylic acids. Dolomite catalysed deoxygenation of fatty acid in WCO into hydrocarbon, consequently accelerating the pyrolysis time to 75 min. Bio-oil at 68.06% yield with 57.27% selectivity towards diesel and gasoline hydrocarbons was obtained at 450 °C while using 6% of dolomite. Dolomite exhibited partial phase separation into dolomite/CaCO3 mixtures within 15 min of pyrolysis, initiated by the generated CO2 during pyrolisis of WCO. The catalyst is stable for up to three reaction cycles suggesting the activity was achieved from the synergy between the dolomite/CaCO3 phases.

This study analyzes the Unibridge system, a modular steel box girder employing two pins for longitudinal connections, thereby expediting construction compared to traditional girders. A finite element model was developed to analyze the stress on these pins in a single-box girder with five segments and a reinforced concrete floor slab. Various loads were applied following the Indonesian bridge loading standard, SNI 1725:2016. The model considers operational load analysis and assumes full composite behaviour between the top flanges of the girder and the concrete floor slab. The results indicate that the Von-Mises stress on the pins reaches a maximum of 490.95 MPa under combined service loads, consistently remaining below the specified material yield stress limit of 1200 MPa. Consequently, the Demand Capacity Ratio (DCR) is 0.41. As a result, the Unibridge girder connection pins do not experience plastic deformation under the applied loads.

This study aimed to analyze the community's disaster response awareness during the Covid-19 pandemic during the implementation of The Large-Scale Social Restrictions (LSSR) in Gresik. Self-awareness was observed using Peter L. Berger and Thomas Luck man's Social Construction Theory through a dialectical process of internalization, objectification, and externalization. The results showed that there had been no good awareness in efforts to prevent the spread of Covid-19 in Gresik. Socially, the community had not taken the dangers of Covid-19 seriously. There was also an inconsistency between knowledge and reality related to disaster response. In coping with the dialectical process, the community had not implemented a disaster-aware culture by obeying the existing regulations. At least, the sociocultural environment determined a person's construction for self-identification, interaction, and adjustment to the social changes that occurred. Hence, the sociocultural construction of the community had never made the disease outbreak a serious problem and considered it as well as God's reminder even though infected cases continued to increase. A situation was indeed difficult for the Task Force to succeed in the Large-Scale Social Restrictions (LSSR) to Community Activities Restrictions Enforcement (CARE) suppressed the increase of Covid-19 positive cases in Gresik, Indonesia. This research sees that the government's policies in handling Covid- 19 are not enough, it needs more optimal involvement of community and religious leaders, to provide education on the importance of maintaining health protocols and building self-awareness of the dangers of Covid.

One of the environmentally friendly concrete as an alternative to cement concrete in the future is geopolymer concrete which used a cement substitute in the form of fly ash. To prevent premature cracking of the concrete, this study added fiber types such as polypropylene fiber, and steel fiber (dramix), this experiment with 3 variables namely the addition of polypropylene fiber by 0%, 0.40%, 0.80%, 1.2%, steel fiber of 0.25%, 0.50%, 0.75%, 1.00%, as well as a combination of polypropylene fiber and steel fiber (0.4%P;0.50%D), (0.8%P;0.75%D), (1.2%P;1.00%D) of the weight of the concrete. In this study, using a beam specimen measuring 10x10x50 cm, for each percentage of fiber usage there are 2 beam trials. Geopolymer concrete in this study uses a ratio of NaOH and Na2SiO3 is 2:1 and a constant concentration of 10 Molar, to test the Flexural Strength Test of Concrete at the age of 28 days of concrete. The results of the highest average flexural strength of geopolymer concrete without fiber σl = 78.77 kg/cm2, using polypropylene 0.80% σl =50.50 kg/cm2, and 0.25% steel fiber σl =68.87 kg/cm2, the combination of both fibers (P0.4%; D0.25%) σl =65.34 kg/cm2. These results do not produce good workability, thus affecting the decrease in flexural strength. By increasing the ratio A = 0.35 to 0.45, the geopolymer concrete mix produces better workability with the highest average flexural strength of geopolymer concrete with polypropylene fiber 0.8% σl = 80.107 kg/cm2.

This research is an effort to investigate the understanding of prospective student teachers in the PGSD Study Program at "AS" Universities in Yogyakarta. The focus of the research is the understanding of nationalism and the implementation of literature as a medium of nationalism. This study used quantitative methods. Research data was conducted by conducting surveys and interviews. The survey was conducted using Google Forms media. Interviews were conducted with 30 students. The results showed that students at "U.S." colleges do not all understand national identity. Of the 30 respondents, there was 1 student who did not understand the identity of the nation. However, overall they have read many books on national identity. Students also agreed that the spirit of nationalism is an important factor that every citizen must have. In addition, students agree that the values of nationalism can be taught through literature. As a form of agreement about it, they have also implemented the practice of making poems with the theme of national identity as a representation of the spirit of nationalism. The novelty of this research is that there has been no previous research that investigates the understanding of nationalism for students, especially in the field of literature in the PGSD Study Program.

The road is the main gateway to human life and links essential access points. Some structure pavement failures happened due to the base layer's instability. Fly ash has been used in several parts of pavement structures to increase stability. One significant concern with using fly ash in base course stabilization is its proportion and potential impact on water quality standards. This research aimed to evaluate base course stabilization performance using fly ash-based geopolymers, as well as assess their impact on water quality standards. Materials in this study consisted of aggregate, fly ash, water, and alkaline reagent solutions. The variation of mix considered with a variety of alkaline reagents, namely without alkaline reagents, 3 mol, 6 mol, 9 mol, and 12 mol of NaOH. The ratio between NaOH and Na2SiO3 is 1:2. The use of fly ash in the class A aggregate base course layer has not been able to meet specifications. However, by providing 9 mol of alkaline reagent, the strength of the mixture increases so that the CBR value meets the specifications due to geopolymer bonding. When the alkaline reagent solution becomes more concentrated, the optimum water content decreases, and the bond between aggregates strengthens. The effect of alkaline reagents on water quality standards increases the acidity (pH) value, while other parameters such as BOD, COD, and TSS still meet the standards. This research point to another practical approach that is effective in the field to increase the stability of the base course layer and is environmentally friendly.

The purpose of this study was to investigate how public sector workers in Indonesia use e-learning systems and how they can benefit from them. The researchers analyzed five variables that contribute to the effectiveness of e-learning: system reliability, information sharing, service quality, user satisfaction, and net benefit. Structural Equation Model analysis was used to analyze the data collected from 203 respondents who were public sector employees in Indonesia. The findings of this study revealed that information sharing, and service quality significantly impact user satisfaction, which in turn has a significant effect on net benefits. Additionally, system reliability was found to significantly impact user satisfaction. This theoretical implication suggests that there is a direct relationship between the level of information sharing and service quality provided by a public sector organization and the level of user satisfaction experienced by its usage of e-learning. The practical implication of the finding is that public sector organizations must prioritize the reliability of their e-learning systems. This includes investing in regular maintenance and updates, ensuring proper testing and quality control procedures, and addressing any issues or downtime quickly and effectively.

This study presents a direct multicomponent analysis method using UV-Vis spectrophotometry to determine Cu(II), Fe(III), and Ni(II) ion content without prior complexation or separation. Single and multivariate regression was used to predict metal ion content, and the resulting model was trained and validated using a dataset of 25 multi-component samples. The mean recoveries for Cu(II), Fe(III), and Ni(II) using linear and ridge regression based only on absorbance at 805 nm were 99.97% and 101.6%, 95.42% and 95.65%, and 99.43% and 99.99%, respectively, for the 20% test data. The mean recoveries for Cu(II), Fe(III), and Ni(II) using linear and ridge regression based only on absorbance at 805 nm were 92.27% and 95.03%, 125.3% and 124.11%, and 104.15% and 105.52%, respectively, for the test solution outside of the training data. These results demonstrate the effectiveness of the multivariate UV-Vis spectrophotometric method for the simultaneous determination of Cu(II) and Ni(II) in multicomponent samples, which meets the analysis standard and can be successfully applied. Finally, the study sheds light on the influence of spectral interference on the accuracy of regression models. It highlights the importance of carefully selecting the wavelengths used as predictors in such models. This can have significant implications for developing and validating analytical methods, particularly in cases where multiple analytes were present in a sample.

The production of coconut and durian means that it will produce a lot of waste from its shell. Indonesia is a country that produces a lot of them. The coconut shell (CS) and durian fruit peel (DFP) can be converted to briquette as new fuel from biomass. The objective of this research is to obtain the calorific briquette properties of CS and DFP using Differential Scanning Calorimetry (DSC). The material composition consist of 10 % and 15 % of starch for each CS and DFP. Thermal treatment was carried out in the temperature range of 28 °C to 600 °C at 5.4 °C/min. The addition of starch causes the heating temperature since it has thermoplastic properties. Additionally, it is difficult to burn and carries a lot of water so that the heat generated is used to evaporate the water first of all in the briquettes. The recommended material is CS with 10 % mass of starch. The optimum temperature reached was 578.97 °C with an enthalpy value of 0.42 J/g.

Incorporating ethnoscience into lessons through the ethnoscience-students' worksheet (ESW) is one method to improve student interest in science learning while introducing them to the local culture. However, no research was reported the effects of ESW on students' responses and the factors that influence ESW implementation in science learning. In order to better understand how students learn through ESW, this study investigated the relationship between ethnoscience context, science learning, and the implementation of students' worksheets. Seventy-two students participated in the survey after they studied ethnoscience learning through ESW. Students' responses are more influenced by science learning. In addition, the ethnoscience-integrated students' worksheets (SW) variable indirectly affects students' responses. Additionally, ESW affects students' responses more significantly than science learning and ethnoscience. This research provides insightful implications for educators on planning, designing, and practicing ESW to enhance students' problem-solving motivation and academic achievement. Furthermore, to contribute significantly to future researchers, further research employed the structural equation model through covariance analysis, also known as confirmatory factor analysis (CFA).

Albumin is a water-soluble protein that has attracted attention due to its characteristics, including biocompatibility, biodegradability, non-immunogenicity, long half-life, minimal toxicity, good stability, and good reactivity. These good characteristics make albumin can be applied in various fields. Albumin can be used in medical and pharmacy as drug delivery and infusion therapy.

This research aims to assess the effect of temperature gradient developed within the concrete slab of rigid pavement, and to investigate its impact when incorporated with the traffic load, and the heat transfer pattern. The rigid pavement model considers an isotropic, uniform, and linear-elastic schemes to simulate the material properties. A numerical analysis approach was employed using Abaqus software incorporated with the 3D Solid model. The traffic loads were obtained from the field surveys, while the temperature of the slabs was measured directly on the site. The dimension of the rigid panel is 2.75 m in width, 5 m long, slab thickness of 25 cm, and concrete specification of 41.33 MPa. The results showed that the temperature gradient produced a significant impact on stress development within the concrete slab of rigid pavement. It was observed that the temperature gradient during the daytime generated higher stress than at night, with a value reaching the MOR (Modulus of Rupture). The exposure of the rigid pavement to 500C tends to produce a principle slab stress of 2.395 MPa, while 1.31 MPa was developed due to the traffic load. When the two factors were combined, the concrete slab acquired a maximum principle stress of 3.322 MPa, which is close to the MOR of 83.34% fa. These results showed that the pavement is capable of withstanding stress from temperature gradient and traffic load as indicated by the ratio of less than one (1). However, this ratio is high for fatigue failure mitigation purposes, and this reduces the quality of life of the rigid pavement.

Titanium Silicate-1 (TS-1) has been successfully modified by combining Silver (Ag) metals. In this study, the preparation of Ag/TS-1 was carried out by impregnation method using a solution of silver nitrate (AgNO3) as a precursor to TS-1 with a loading variation of 0.5%, 1%, 2%, and 4%. Impregnation carried out on TS-1 aims to disperse Ag (1) only attached to the surface of TS-1 particles (before calcination/TK) and (2) on the entire surface of TS-1 particles (after calcination/K). The synthesized catalyst was then characterized by X-ray diffraction, infrared spectroscopy, and pyridine adsorption techniques. The XRD pattern shows that all the catalysts have high crystallinity with MFI structure, and there is no other crystalline phase. The infrared spectra showed that the titanium tetrahedral in TS-1 remained after Ag impregnation. The TS-1 and Ag/TS-1 catalysts were analyzed for their surface acidity using pyridine adsorption on the sample. The pyridine adsorption technique showed the presence of Lewis sites on Ag/TS-1. In this study, the presence of Ag loading on the Ag/TS-1 catalyst affected the TS-1 catalytic activity. The amount of cyclohexanone oxime product produced in XAg/TS-1 was more than in Ag/TS-1.
