Published: December 2023

Abstract
Bio-sequestration of CO2 using microalgae to recycle CO2 into valuable products such as single-cell proteins (SCP) is one of the most promising fields nowadays. Microalgae are able to use CO2 as their carbon source and subsequently build carbohydrates, proteins, nucleic acids, and lipids. Nevertheless, all microalgae strains do not have the same CO2 tolerance and culture conditions. Moreover, pure CO2 is less soluble in water, which leads to a low carbon capture and fixation rate. Thus, to optimise SCP production in relation to CO2 mitigation, studies of the enhancement of solubilization of CO2 in water as well as the determination of the optimum process parameter for CO2 fixation and SCP production need to be done. Consequently, this study aims to review the cultivation conditions for single-cell protein production.

Abstract
Recently, Radial Flux Permanent Magnet Generator (RF-PMG) has been applied in various applications of generator. The configuration of the radial flux permanent magnet is the magnetic rotor arranged in a circle rotation while the inner core attached to the rotor’s center. However, various sizes and structure of RF-PMG can produce different output power levels, cogging torque and generator’s flux regulation capability. By investigating the output voltage and cogging torque value, this paper showed the suitable slot-pole combinations that can influence the output performance of the generator by using 2D-Finite Element Analysis. This investigation shows the comparison of the slot-pole that resulting the least cogging torque value and high output voltage, 0.1739Nm and 180.81V respectively. Hence, 36slots-30poles indicates as the best slot-pole combinations.
Effect of fin spacing on the vibration-assisted thermal performance of heat sink
Authors: Rasangika A H D K , Nasif M S , Pao W , Al-Waked R 
Published: December 2023

Abstract
Applying vibrations on heat sinks can induce recirculation zones in the flow field, disrupting the developed thermal boundary layer. This paper demonstrates the fin spacing effect on the vibration-assisted heat transfer of the heat sink. Thermal performance is investigated over a range of 0 -12 Hz vibrational frequencies and fin spacing of 0.008 – 0.014 m. The enhancement of the Nusselt number is insignificant up to the threshold frequency (6 Hz). This threshold frequency is found to be independent of fin spacing. Further increase in vibration frequency leads to higher enhancement in Nusselt value at every fin spacing. However, the vibration effect on the Nusselt number became more prominent at lower fin spacing. In this study, the enhancement of the Nusselt value is up to 8 % at a fin spacing of 0.008 m and a vibrational frequency of 12 Hz.
Quantification of cogeneration vulnerability towards the climate change: framework development
Authors: Fedotova E , Krasheninnikov S 
Published: December 2023

Abstract
Cogeneration is a vigorous measure to both decrease greenhouse gases emissions and improve an overall efficiency of the primary energy use. The climate change poses serious risks on operation of combined heat and power (CHP) plants due to the shifts in heating load patterns. This work investigates linking of the heating demand to the climate conditions and introduces a framework which can be used to develop an adaptation strategy for district heating systems. We demonstrate viability of the proposed approach by a case study assessing sensitivity of the CHP efficiency to the climate warming across China considering a modern combined-cycle gas-fired power plant with steam extraction. Outputs of the case study have demonstrated that CHP plants are generally more vulnerable towards the climate change in world regions with harsher climate conditions. An effective measure to increase resilience of the cogeneration sector is to account for anticipated climate change effects by applying adjustments to the reference climate inputs used when designing CHP plants.

Abstract
The transportation sector constitutes a major source of global greenhouse gas emissions, and the adoption of electric vehicles (EVs) can help mitigate this issue. This paper presents a simulation study examining the performance of lithium-ion and lead-acid batteries for EVs when charged using direct current (DC) chargers. A simulation model is employed to observe the charging behavior of these batteries and analyze the effects of various DC chargers. Factors such as the state of charge (SOC) and charging rate influence the charging behavior of batteries in EVs. The simulation results are compared and analyzed to ascertain the optimal charging strategy and infrastructure for EVs. The performance of different EVs is evaluated in terms of charging time, energy efficiency, and SOC. According to the findings, implementing the appropriate charging strategy and infrastructure for lithium-ion and lead-acid batteries in EVs can significantly enhance performance and encourage the widespread adoption of EVs.
How the presence of public charging infrastructure can impact the adoption rate of electric vehicles in the UK
Authors: Hafezi Sahba Ghiasi , Morimoto Risa 
Published: December 2023

Abstract
In the current work, the presence of public charging facilities and their impact on the adoption rate of Electric Vehicle (EV) are studied across 363 Local Authorities (LA) districts in the UK. This analysis is conducted utilizing the data from the UK government on the location of public electric vehicle chargepoints in various LAs as well as the EV ownership rate between years 2011 and 2021. Various rural, urban and extra urban (e.g. London) regions are analyzed to assess whether EV ownership has been impacted as the charging infrastructure is rolled out in these regions. The quarterly data on the number of licensed Ultra Low Emission Vehicles (ULEV) in each UK local authority is used to track EV ownership levels. The results indicate that the publicly available charging points stimulate the diffusion of EV adoption; however, this varies by region and saturation. The reverse effect of EV ownership on charging infrastructure rollout by Local Authorities cannot be entirely rejected; however, the positive stimulus of public infrastructure on adoption of EV is established. The findings can provide the UK policy makers with insight into the public charging infrastructure requirements and benefits in short to medium term to meet the committed emission reduction targets by 2035 and 2050.

Abstract
Global rubber production has declined over the past few years as a result of a number of variables, including both environmental and human factors. In this paper, an automated robot prototype that collects latex cups was developed to improve global rubber production by assisting workers in rubber plantations. The robot was built on a mobile platform with a motorized Five Degrees of Freedom (DoF) robotic arm, Ackermann steering, double wishbone suspension, rear-wheel drive and a latex storage tank to store the latex collected from the trees. The robot was equipped with ultrasonic sensors and a camera module to locate latex cups and rubber trees so that it could move and perform tasks accurately. In addition, encoder sensor modules were used to improve the accuracy of the movements by measuring the rotational speed of the motors. The yield strength of the PLA plastic material used in developing the latex cup collector robot is 7.00 x 107N/m2 and the maximum stress of the critical parts should not exceed the maximum yield strength of the PLA plastic. In mobility test, the robot is able to travel through obstacles of 10mm and 15mm height. The topple angle of the robot in the balancing test is greater than 37°, ensuring the stability of the robot.

Abstract
The increase in salt imports by the Indonesian government should prompt coastal communities endowed with extensive marine resources to improve their salt production, subsequently catering to the demands of the industrial sector. The primary objective of the target village empowerment program is to assess the impact of implementing geomembrane technology on the augmentation of revenue among salt producers residing in Bulu Cindea Village, located in the Pangkep Regency. The present study employed descriptive analysis and income analysis methodologies. Descriptive analysis offers a more accurate depiction of the indigenous knowledge and practices used by salt pond producers. The examination of income assesses the earnings of salt pond farmers about implementing the PDB program. The present study examined the potential enhancement of pond farmers’ income through implementing the PDB program. This was accomplished by analyzing variance, followed by a t-test, to assess the impact of salt farmers’ income on adopting geomembrane technology. The results revealed a statistically significant difference (p < 0.05) between salt farmers’ income before and after the utilization of geomembrane technology, indicating a positive effect on their overall income. The findings suggest that implementing the PDB program, specifically through geomembrane technology, can enhance the socioeconomic conditions of salt producers residing in Bulu Cindea Village.

Published: December 2023

Abstract
Tropical cyclones (TC) are atmospheric phenomena categorized as extreme weather that is perilous and destructive. The parameters used include sea surface temperature (SST), wind speed (WS), and air pressure (AP), which are factors in the formation of TC. The emergence of TC occurred in October 2020, when it grew in Philippine waters and died out in Vietnamese waters. The characteristics of the waters of the South China Sea (SCS) in particular and the Pacific Ocean in general make them one of the waters with the highest storm potential in the world; therefore, this research was conducted. The purpose of this research is to understand the characteristics of Saudel Cyclone (SC) based on the parameters SST, WS, and AP, which are obtained from the ECMWF website, to be able to describe the process of growth until the extinction of SC. Data from the ECMWF website has limitations because it is model data (re-analysis). The results of this study can determine the process of starting the extinction of SC as well as the characteristics of SST, AP, and WS in the conditions of starting SC, during the peak of SC, and starting the extinction of SC.

Abstract
The Spanner Barb Striuntius lateristriga is a freshwater species from the Cyprinidae family that spread in Southern Thailand; the Malay Peninsula, Singapore and Indonesia. The previous presence of the Spanner barb in Indonesia was recorded in West Kalimantan and Bangka Island. This study was carried out to record for the first time the presence of S. lateristriga on Belitung Island, Indonesia. The presence of S. lateristriga in the Belitung archipelago adds knowledge about the new distribution and biogeography of freshwater species. Moreover, information on this species’ new distribution is critical for supporting suitable conservation policies and measures. The twenty S. lateristriga specimens were collected on January 20, 2023 utilizing a fish trap at the Gurok Beraye waterfall, Gunung Tajam, Belitung Island, Indonesia. This specimen was identified based on specific literature. The new record of S. lateristriga provided here is the southernmost record for this species, expanding its geographic distributing. In addition, the new record site is 250 km southeast of the nearest locality in Bangka Island, and about 500 km south-west from the nearest locality in Borneo. Futrhermore, understanding biodiversity, range extension, and biogeography of the species in Sundaland will enrich knowledge in science.

Abstract
The COVID-19 pandemic has had an impact on the seaweed industry due to changes in supply and demand, cost increases, market volatility, and the implementation of lockdown measures. This study aimed to determine the effect of the COVID-19 pandemic on the seaweed industry to support a sustainable food system. This study used both primary data from the seaweed industry, especially the upstream sector, and secondary data to determine the progress of the national and international seaweed industries. The data was analyzed descriptively to obtain information regarding the role of the seaweed industry in accelerating post-pandemic coastal economic recovery. The results indicated that seaweed cultivation can support coastal economic recovery in the post-COVID-19 pandemic. After demand recovers, production can be enlarged in a short time without excessive investment and has the potential to generate income within 30–45 days. It was found that total seaweed exports have dropped by 30.54% and 19.90% by volume and value, respectively, in only the early stages of the COVID-19 outbreak. However, the effect of the pandemic has encouraged accelerative industrialization by increasing the capacity of domestic seaweed factories from 50% to 72%. The pandemic has also triggered the domestic industry to produce seaweed derivative products independently, such as carrageenan, alginate, and agar, to reduce dependence on imports. It is imperative to recommend to the Indonesian government that the export tariff on dried seaweed be increased to boost the competitiveness of the domestic seaweed processing industry and invest in the diversification of processed seaweed derivative products.

Published: December 2023

Abstract
Surimi is widely used as the main ingredient for various innovative seafood products (ISP), e.g., imitation crab meat, fish balls, fish sausage, kamaboko, fish sticks, and paupiette. Sodium chloride (NaCl), a primary ingredient of surimi, plays an important role in gelling and flavor. A reduced-NaCl product is preferred by consumers due to health-related reasons. This study focuses on evaluating the gelling characteristics of fish surimi gel formulated with different levels (0.5, 1, and 1.5%) of calcium hydroxyapatite (HAp). Surimi gel added with HAp showed a good gel-forming ability (p<0.05). The texture profile analysis indicated an acceptable value. As for the water-holding capacity (76.88%), the highest value (p<0.05) was recorded for 1% of HAp addition. On the contrary, the cooking loss (21.09%), expressible moisture content (23.48%), and whiteness index (70.20) for samples with 1% HAp were the lowest compared to other samples. This preliminary finding suggests that the addition of calcium HAp at 0.5 to 1% could be an alternative ingredient to NaCl for maintaining gelling characteristics of surimi. It also adds nutritional value to the product. This finding could be a reference to the industry in improving the processing of surimi-based products.
