Published: December 2023

Abstract
Phase change materials (PCMs) stores and releases thermal energy in the form of latent heat during phase transition. Though PCMs are durable in nature, they suffer commercial application owing to low thermal conductivity. Inclusion of metal and carbon based nanoparticles are typically adopted to overcome the complication of poor conducting nature of organic PCMs. In this experimental research we develop a bio based nanoparticle using coconut shell in an environmental friendly manner to enhance the thermal conductivity of organic PCM polyethylene glycol 1000. Bio nanoparticle (BNP) improves the thermal conductivity of the developed nanocomposite PCM by 73.1% with 0.9 wt% of coconut shell BNP hence we evaluate the thermodynamic and thermal kinetics parameter of the nanocomposite PCM sample with 0.9 wt% biochar based nanoparticle. In addition the authors have analysed the thermal decomposition kinetics of the optimized PCM composite using Coats and Redfern method to exhibit the reaction mechanism, thermodynamic and kinetic parameter.

Abstract
Inorganic salt hydrate phase change materials (PCMs) are ahead of organic PCMs in terms of energy storage ability and safety as they are non-flammable. However the major hindrance with inorganic PCM are degree of supercooling and low thermal conductivity though better than organic PCM. The common technique to enhance the thermal conductivity is via dispersion of metal and carbon nanoparticle. Though they enhance the thermal conductivity of the nanocomposite, with continuous operation the nanoparticle agglomerate and settles down owing to their density. Henceforth, in the current research work we conduct an experimental investigation to enhance the optical and thermal performance of commercialised inorganic salt hydrate PCM using metal-carbon hybrid nanoparticle. We disperse graphene silver nanoparticle at different weight ratio adopting a two-step method followed by probe sonication to ensure uniform dispersion. We achieve a highly stable nanocomposite with 584% increase in optical absorbance of electromagnetic waves and 86% decrease in transmittance. Thermal management of electronic gadgets has evolved to be a major consideration of research as overuse of gadgets lead to rapid temperature rise and is in need of passive cooling system. Henceforth the newly developed nanocomposite phase change materials (PCMs) not only acts as thermal batteries but can also be opted as energy materials for thermal regulation and heat mitigation.

Abstract
In this work Ag/AgCl planar pseudo-reference electrodes (pREs) were fabricated and studied. The pRE was derived from typical copper-cladded flame retardant 4 (FR4) board, with layers of Ni, Au, and Ag electrochemically deposited sequentially. Lastly, the AgCl layer was obtained through electro-chlorination process. The morphology and Open Circuit Potential (OCP) of the samples were obtained from characterizations. It was revealed that the Au layer consisted of finer grains compare to that of Ag having larger granular structure. There was also morphological difference between as-prepared AgCl and post OCP run AgCl, where the later show signs of degradation. Based on the potential-transient curve of electro-chlorination, chlorination process took place on the surface of Ag, subsequently diffused into the bulk layer. Sample chlorinated for 1 min shows better stability in OCP test where the potential exhibit minimum changes. The duration of the sample being stable during electrochemical process was 10 minutes.

Abstract
Malaysia has pledged to GHG emissions by 45% by 2030 in light of the urgent need to reduce global emissions. One approach used by the government is to concentrate on energy sustainability programs, such as energy efficiency (EE). The success of this approach relies on the support from various parties. Persuading non-technical management and staff, however, might be particularly difficult. Hence, besides the technical-based impact, it is important to analyse the environmental and financial-based impact too. This paper portrayed the EE initiatives that could assist in reducing energy (kWh), cost (RM), and CO2 (tonne) simultaneously. The number of trees needed to neutralise or offset an emission might later be related to a reduction in CO2. A case study of Wisma R&D, UM was referred. The environmental-based impact of the lighting retrofitting projects at Wisma R&D was used in this study to illustrate the importance of EE approaches. Both parameters are obtained from the online Greentech carbon calculator. A 144,386 kWh annual savings resulted in RM 52,701 in cost savings, and a decrease of 100.2 tonnes of CO2 emissions was achieved. Ultimately, based on the decrease in CO2, 2569 fewer trees are needed to offset the emission.

Abstract
This experimental study intent to design and to analyse the passive cooling effect of an Earth-Air Heat Exchanger (EAHE) integrated into the building ventilation system. For hot climate regions, ground thermal inertia can be used as a passive cooling strategy in the building ventilation where the air supply comes from outside with hot temperature. The proposed EAHE device consists of two main-components; a water tank and a PVC hose as a heat-exchanger between air and water in the tank. Fresh air from outside with a flow rate of 5.63 kg. min-1 is blown through a 2 ½-inch PVC hose, and cooled by the low water-soil temperature before being distributed into the room. To analyze the effectiveness of the passive cooling effect, measurements are performed for several parameters; inlet and outlet air temperature of ventilation ducts and indoor-outdoor air temperature using a multichannel thermocouple data logger for 48 hours of measurement time. The results present that the EAHE device can reduce the air temperature to a maximum of 10.6 °C. This proposed EAHE device presents good performance as a passive cooling technique for a building ventilation system, especially during the day.

Authors: Hidayat M F , Ustadi  
Published: December 2023

Abstract
This study aims to determine the effect of the addition of CaCO3 as a whitening agent on the quality properties of the skipjack surimi. The functional properties were evaluated using physical and chemical tests, including white degree analysis, folding test, texture test, water holding capacity, and fat content analysis. Skipjack surimi was carried out in four treatments: 0%, 0.5%, 1%, and 1.5% CaCO3 in a completely randomized design (CRD). The results revealed that adding 1.5% CaCO3 achieved the highest white degree value of 54.22. The folding test values increased with higher CaCO3 concentrations, ranging from 1.57 (control) to 2.05 (1.5% CaCO3). Surimi fat content analysis showed no significant differences (P>0.05) between treatments, varying from 1.16% in the control to 1.51% in the 1.5% CaCO3 treatment. Furthermore, the WHC of skipjack surimi was significantly different (P<0.05) between treatments and increased with the addition of CaCO3: 52.44% (0% CaCO3), 66.42% (0.5% CaCO3), 74.57% (1 % CaCO3), and 79.96 % (1.5% CaCO3). However, sensory color tests showed a significant difference (P<0.05) between the treatments. In conclusion, the incorporation of 1.5% CaCO3 as a whitening agent resulted in an optimal treatment with a folding test value of 2.05 and a WHC value of 79.96%. These findings suggested the potential use of CaCO3 to enhance the functional properties of skipjack surimi during production.

Published: December 2023

Abstract
This study aims to determine the effect of jellyfish meat substitution in the production of catfish nugget on the nutrient content and acceptability of the nugget, and to determine the best composition to produce quality nugget. The research design used a completely randomized design (CRD), there were 4 types of treatment with 3 replications. The treatments were the percentage of catfish meat: jellyfish meat including T0 (100:0), T1 (90:10), T2 (80:20) and T3 (70:30). Parameters measured were hedonic organoleptic characteristics (aroma, taste, texture and overall) and nutritive content (moisture, ash, fat and protein content). The data obtained were analyzed using the ANOVA test (Analysis of Variance) and if there was a significant difference then it was continued with the Duncan test. The results showed that the hedonic value of catfish nuggets substituted for jellyfish meat gave a significant difference (p <0.05) in each of the parameters tested, namely aroma, taste, texture and overall. The catfish nugget substituted with 20% jellyfish meat (T2) gave the best sensory quality on aroma (3.77), taste (3.67), texture (3.60) and overall score (3.77). The results of testing the proximate content of catfish nuggets substituted for jellyfish meat showed significantly different results (p<0.05) for each parameter. However, all catfish nuggets treated with jellyfish substitution (T1, T2, and T2) as well as treatment without jellyfish substitution (T0) met the quality standards of the nuggets, except for the ash content in the nuggets. It can be concluded that the best formula is in the treatment (T2), the catfish nugget substituted with 20% jellyfish meat with a protein, fat, water and ash content of 10.36%, 2.52%, 13.49% and 5.45%, respectively.

Published: December 2023

Abstract
Pempek is a popular ready to cook fish cake in Indonesia with a high level of moisture content. At room temperature, pempek can only stored for a few hours. There are several variants of pempek available in the market in the form of dried pempek which can be stored at room temperature for a long time. These dried products need to be rehydrated before cooking. The drying technology of dried pempek will affect the characteristics of the ready-to-cook product after the rehydration process. This study aims to determine the effect of freezing before drying on the characteristics of ready to cook rehydrated dried pempek (curly shape pempek). The experimental treatments tested were freezing treatment and non-freezing treatment. Each treatment was repeated in 3 replications of experiment. Freezing process were carried out in a household freezer for 24 hours and the drying process were carried out in an electric oven at 45°C for 12 hours. The results showed that after rehydration, dried pempek could returned to its original characteristics like before drying. Freezing treatment before drying gave a higher rehydration ratio, better texture and lighter appearance than without freezing treatment.

Authors: Putranti L N , Nugraheni P S 
Published: December 2023

Abstract
Bioplastic is an alternative solution in solving the problem of the plastic waste accumulation. Chitosan is a marine product waste from the crustacean group that can be used as a raw material for bioplastic because of its good film-forming ability. However, the bioplastic from chitosan has the property of being easily broken, so another material is added, namely carboxymethyl cellulose (CMC), that increase the bond’s compactness. This study aims to determine the effect of the addition of CMC on the characteristics of bioplastic made from 2% chitosan and 0.5% glycerol with a volume ratio of 10:1 chitosan:CMC. The experimental design used was a completely randomized design (CRD) with the addition of CMC (0%, 0.25%, 0.5%, 0.75% and 1%). The characteristics of the bioplastic tested in this study included film thickness, density, water content, solubility, tensile strength, elongation, antibacterial activity, and functional group analysis. The addition of 0.5% CMC resulted the bioplastic with a film thickness of 0.072 mm, the density of 0.836 g/cm3, the water content of 16.99%, the solubility of 40.5%, the tensile strength of 12.83 MPa, the elongation of 41.76%, inhibition zone of the antibacterial activity of 2.83 mm and a new group is formed in film that was made.
Experimentally seeded social cues in the wild: costs to bearers and potential benefits to receivers
Authors: Doherty Clare T M , Laidre Mark E 
Published: December 2023

Abstract
Conspecifics can provide social cues about the presence of key features of the surrounding environment, such as food or predators. Attending to social cues may therefore potentially benefit receivers, or at least be worth following. Yet, bearing social cues could also be costly, particularly if it increases the likelihood of close-range interaction with non-kin. Here, we experimentally seeded social cues in the wild onto focal individuals of the social hermit crab (Coenobita compressus), testing (1) the “potential benefits to receivers” hypothesis, which predicts that receivers will follow social cues to orient toward valuable resources, and (2) the “costs to bearers” hypothesis, which predicts that bearers of social cues will experience direct (physical) costs or indirect (constrained movement) costs due to interaction with receivers. Consistent with hypothesis (1), in natural encounters, conspecifics that crossed paths frequently made antennal contact, potentially gathering social information at close range. In experiments, naive conspecifics followed focal individuals bearing “positive” social cues (about a valuable food resource) significantly more often than they followed individuals bearing less attractive (“neutral” or “ambivalent”) social cues, pointing to a potential benefit. Consistent with hypothesis (2), individuals bearing positive social cues incurred greater direct and indirect costs, being physically flipped more often and achieving shorter displacements compared to individuals bearing other social cues. We conclude that experimentally seeded social cues in the wild can confer costs to bearers and potentially benefit receivers. Broadly, the costs of bearing social cues, revealed here, underscore the importance of not overlooking that social cues may be costly.

Abstract
Patients living with inherited skin diseases have benefited from recent advances in DNA sequencing technologies that provide new or improved diagnostics. However, developing and delivering new treatments for the ‘genodermatoses’ remains challenging. The goal of creating topical preparations that can recover the inherent gene pathology remains largely aspirational. However, recent progress in two fields – the chemistry of topical delivery formulations (lipid nanoparticles) and the molecular biology of gene repair (CRISPR-Cas9, base and prime editing) – presents new opportunities to address this unmet need. In this review, we discuss how lipid nanoparticle delivery vehicles could be used to deliver gene-editing tools to formulate topical ‘gene creams’ suitable for the treatment of genodermatoses. We summarize the historical landscape of topical therapeutics and advances in gene editing that may herald an era of new therapies for patients with inherited skin disorders.
