Authors: Agusta H , Nisya FN , Adam MF , Iman RN 
Published: May 2023

Abstract
Probably effective application of fly ash granules for ameliorants on sugarcane has not been meaningful reported in tropical agricultural systems and no exact results have not been established. The experiment was arranged from January 2014 up to May 2015 at IPB Bogor, Indonesia. This study aimed to determine the improvement level of additional fly ash granules as soil ameliorants on peat soil in sugar cane cultivation compared to the application of dolomite. The experiment used a complete randomized block design in sub-optimal peat soil. There were five levels of treatment at 50 kg peat soil weight at polybag as the following: without the addition of ameliorant as control (C0) at pH=4.0; Mixing with fly ash granule at pH 6.0 (C1); Mixing with fly ash granule at pH 7.0 (C2); Mixing with dolomite at pH 7.0 (D1), Mixing with dolomite at pH 6.0 (D2). The fly ash granule and dolomite application at a starting value of pH 6.0 or pH 7.0 exposed reliable impact to maintain the pH value of peat soil at least for one year during the growth of the sugarcane plant biomass until harvest. The application of fly ash granule at the starting value of pH 6.0 showed a better effect on plant growth biomass and was sufficient to ameliorate the peat soil to achieve the optimum sugar yield. More than this application rate would be luxurious, it causes no increase in sugar production.

Abstract
Plant-derived reusable resources such as biomass feedstock for fuel use and upcycling food products have attracted attention for solving environmental problems. In general, food products that are inappropriately consumed include various energy production pathways through the fermentation or gasification process, which would be attractive for solving the anaerobic digestion of wasted foods to make livestock feed. In terms of comprehensive aspects, the use of upcycling food products in various ways is also significant for abating environmental burdens. For instance, products made from unutilized food through cooking, such as jams made from banana peels, have been increasingly marketed. However, while the preparation of unused food reduces food loss, the environmental impacts of their life cycle have not been well considered. To date, our research group has discussed effective consumption pathways, including recycling pathways for the edible parts of foods. For instance, a 100 g edible part of tomato has an environmental impact of 35–57 g-CO2 emissions during the cooking stage. The environmental impact of waste would not be negligible. Therefore, the eco-burden mitigation in the entire life cycle stage is discussed based on the proposal of a practical pathway, comparing the other paths (e.g., energy use).

Abstract
Indonesia commits to reducing emissions by 29% (unconditional) or 41% (conditional) in 2030, which can be achieved by encouraging the use of new and renewable energy (NRE) by 23% in 2025 while realizing national energy security. A biofuel development plan through a mandatory biodiesel program and green fuel utilization is the main priority to reduce fossil fuel consumption and achieve the energy mix target. As of January 1, 2020, through the mandatory biodiesel program, biodiesel utilization reached 30% (B30) for all diesel engine sectors, which is the highest biodiesel blending program in the world. However, the gap between government policies with emission regulation and existing vehicle technologies in this country might provide challenges in strengthening the sustainability of mandatory biodiesel programs. This study used a normative juridical method to assess the policy and enhance the regulation of the mandatory biodiesel program by obtaining library materials, theories, concepts, principles, and existing rules related to the law perspective. An appropriate and consistent energy mix policy, including its long-term strategy to increase biofuel utilization and maintain a mandatory biodiesel program, is needed to achieve a reducing emissions target. It is essential to strengthen and clarify the policy and road map. The vehicle technology and fuel quality were also crucial for enhancing emission regulation and eliminating low-quality fuels, maintaining a sustained biodiesel program, and achieving national energy security.
Vulnerability and Capability Factors for the Indonesian Biodiesel Supply Chain Resilience

Abstract
Biodiesel is one of the biofuels identified as a complement to conventional fuels. Socially and environmentally, biodiesel has been known to provide benefits for creating new jobs, revitalizing rural areas, and reducing global warming. However, the biodiesel industry often faces various challenges, one of which is uncertainty in decision-making. Uncertainty in the supply chain is considered as one of the greatest challenges to managing and controlling the supply chain. Other types of uncertainty are associated with events that decision-makers cannot predict or control, such as natural disasters, accidents, or artificial disasters. Supply chain complexity and global competition have increased their exposure to disruption. Therefore, reacting appropriately to disruptions is necessary for business continuity. Ultimately, resilience capabilities must be developed to help companies become more resilient than before. This paper identifies and determines the vulnerability and capability factors in the Indonesian biodiesel supply chain. The result shows several vulnerability factors, such as turbulence (price, technological failure, and pandemic), external pressures (policy and regulation), and resource limits (supply, capacity, and land availability), that may affect the resilience of the biodiesel supply chain. Meanwhile, capability factors that can be utilized to reduce these vulnerabilities are flexibility in sourcing, flexibility in order fulfilment, capacity, adaptability, visibility, and collaboration. The practical implications are also described in this paper.

Published: May 2023

Abstract
The production system for industrial oil and gas is susceptible to corrosion, which must be controlled in order to sustain production and well direct as the production of tubing is the initial point of contact with the corrosion fluid and material agent. A chemical reaction between corrosive materials and fluids results in corrosion. Due to its mechanical characteristics, stainless steel has a wide range of uses in the building, chemical, and structural sectors. To combat corrosion issues, several chemical inhibitors are used, and numerous studies are actively working to develop organic inhibitors. Rhizome ginger is an organic component that has a high phenol antioxidant content and antioxidant compound, making it useful for corrosion issues. In this study, the effect of monoethylene glycol and ginger extract inhibitors on corrosion was reviewed. The corrosion rate was computed using an olga simulator, and the influence of the inhibitor on the rate of corrosion and the effectiveness of the inhibitors was examined.
Isolation and Characterization α-Cellulose from Cocoa Pod Husk using Peracetic Acid

Published: May 2023

Abstract
Cocoa Pod Husk (CPH) is the main by-product of cocoa pods (Theobroma cacao L.) with 67-76% of fruit weight. However, CPH has a negative impact if it is not utilized and disposed of directly in the environment. The main fiber content in CPH is in the form of lignin, cellulose, hemicellulose, and pectin. Cellulose content, especially α-cellulose has a high potential if it is further utilized, one of which is nanocellulose. This study aims to produce α-cellulose from cocoa husks with high purity. The first research activity carried out was the process of removing pectin and bleaching to be free from impurities such as pectin, lignin, and hemicellulose. Then the cellulose isolation process using Peracetic Acid (PAA) can shorten the α-cellulose isolation process. The variation of PAA concentration was 1:4 (mol/mol) without dilution; 1:4 (mole/mole) by dilution; and 1:1 (mole/mole). The results of this study were the highest α-cellulose content of 69.39% was obtained from a 1:4 mole ratio of PAA without dilution. However, the α-cellulose content obtained did not qualify the SNI 938-2017 standard, which was 94%. FTIR, XRD, and SEM characterization showed that α-cellulose was present in hydrolysed CPH.

Published: May 2023

Abstract
Lipase is an enzyme commonly applied as a catalyst in the food industry, the synthesis of bioplastics, and the production of biodiesel. Candida rugosa lipase (CRL) is one of the widely used lipases due to its high selectivity and activity. However, high operating temperatures can denature enzymes, affecting enzyme activity due to structural changes. An enzyme can be immobilized on a supporting matrix to improve stability. Ethanol as an immobilization solvent may also increase the thermostability and esterification activity. This study examines the effect of ethanol solvent on the thermostability of immobilized Candida rugosa lipase. Immobilization was carried out on the Celite-545 matrix in buffer/ethanol solution. Different operating conditions such as enzyme concentrations, immobilization temperatures, immobilization time, and immobilization pH were observed. The immobilized enzyme activity was determined by esterification reaction using butyric acid and 1-butanol as substrates and isooctane as reaction medium. The results showed that immobilization increased the esterification activity by 76% at 37°C. Thermostability of immobilized enzyme was also enhanced by 29-51%, depending on the esterification temperature.

Published: May 2023

Abstract
Stretchable electronics can be realized using different manufacturing methods and hybrids thereof. An example of the latter is the combination of stretchable circuit boards with screen-printing, which will be discussed in this work. The hybrid stretchable electronics structures are based on photolithographically structured and rigid copper islands and screen-printed silver ink interconnections. This enables the assembly of components with a high number of contacts onto the copper islands and deformable silver ink lines between islands. The transition area between islands and lines is critical due to local stress concentration. The effect and potential mitigations were studied by measuring the electrical resistance of test interconnections under mechanical loading. The first set of samples was elongated up to 30% in tensile tests. The second set of samples was elongated 10%, 20%, and 30% in cyclic tests up to 10 000 cycles. After the tests, extensive failure analysis, e.g. scanning electron microscope, and finite element analysis were conducted. In tensile tests at maximum load, the interconnections either snap apart or their resistance increases by 640% in the transition area. Adding protective structures around the transition area, the resistance increase can be reduced to 12%. Stress concentration in the transition area can be controlled with the layout of the structures, as shown in the cyclic tests. Depending on a layout, the structures protect interconnections in the transition area (resistance <4 Ω at 10% and 20% throughout 10 000 cycles, and up to 5000 cycles at 30% elongation), or with particular designs, cause fatal damage of the circuitry and fail early. The identified failure mechanism is typically fatigue damage caused by the repeated bending of the protective structure. The observed resistance increase at the interface was closely related to the crack propagation phase in the protective structures.

Involvement of ionic interactions in self-assembly and resultant rodlet formation of class I hydrophobin RolA from Aspergillus oryzae
Authors: Takahashi Nao , Terauchi Yuki , Tanaka Takumi , Yoshimi Akira , Yabu Hiroshi , Abe Keietsu 
Published: May 2023

ABSTRACT
Hydrophobins are small amphiphilic proteins that are conserved in filamentous fungi. They localized on the conidial surface to make it hydrophobic, which contributes to conidial dispersal in the air, and helps fungi to infect plants and mammals and degrade polymers. Hydrophobins self-assemble and undergo structural transition from the amorphous state to the rodlet (rod-like multimeric structure) state. However, it remains unclear whether the amorphous or rodlet state is biologically functional and what external factors regulate state transition. In this study, we analyzed the self-assembly of hydrophobin RolA of Aspergillus oryzae in detail and identified factors regulating this process. Using atomic force microscopy, we observed RolA rodlet formation over time, and determined “rodlet elongation rate” and “rodlet formation frequency.” Changes in these kinetic parameters in response to pH and salt concentration suggest that RolA rodlet formation is regulated by the strength of ionic interactions between RolA molecules.

Abstract
To quantify the biases introduced during human gut microbiome studies, analyzing an artificial mock community as the reference microbiome is indispensable. However, there are still limited resources for a mock community which well represents the human gut microbiome. Here, we constructed a novel mock community comprising the type strains of 18 major bacterial species in the human gut and assessed the influence of experimental and bioinformatics procedures on the 16S rRNA gene and shotgun metagenomic sequencing. We found that DNA extraction methods greatly affected the DNA yields and taxonomic composition of sequenced reads, and that some of the commonly used primers for 16S rRNA genes were prone to underestimate the abundance of some gut commensal taxa such as Erysipelotrichia, Verrucomicrobiota and Methanobacteriota. Binning of the assembled contigs of shotgun metagenomic sequences by MetaBAT2 produced phylogenetically consistent, less-contaminated bins with varied completeness. The ensemble approach of multiple binning tools by MetaWRAP can improve completeness but sometimes increases the contamination rate. Our benchmark study provides an important foundation for the interpretation of human gut microbiome data by providing means for standardization among gut microbiome data obtained with different methodologies and will facilitate further development of analytical methods.
Noise Reduction of Electron Holography Phase Maps with Non-Local-Mean Wavelet Analysis
Authors: Wang Shixin , Wang Yun-Yu 
Published: May 2023

Abstract
A non-local-means algorithm with non-local averaging is used to reduce noise in an electron holography phase map. The noise level is evaluated through wavelet analysis. The method is shown to be effective in reducing noise in the map while preserving both the spatial resolution and underlying map information. Because of the significant noise reduction, the processed phase map is easier to understand and can produce an internal electric field map with a derivative of the phase map.

Published: May 2023

Abstract
Human meiosis in oocytes entails an intricate regulation of the transcriptome to support late oocyte growth and early embryo development, both crucial to reproductive success. Currently, little is known about the co- and post-transcriptional mRNA processing mechanisms regulating the last meiotic phases, which contribute to transcriptome complexity and influence translation rates. We analyzed gene expression changes, splicing and pre-mRNA processing in an RNA sequencing set of 40 human oocytes at different meiotic maturation stages, matured both in vivo and in vitro. We found abundant untranslated region (UTR) processing, mostly at the 3′ end, of meiosis-related genes between the germinal vesicle (GV) and metaphase II (MII) stages, supported by the differential expression of spliceosome and pre-mRNA processing related genes. Importantly, we found very few differences among GV oocytes across several durations of IVM, as long as they did not reach MII, suggesting an association of RNA processing and successful meiosis transit. Changes in protein isoforms are minor, although specific and consistent for genes involved in chromosome organization and spindle assembly. In conclusion, we reveal a dynamic transcript remodeling during human female meiosis, and show how pre-mRNA processing, specifically 3′UTR shortening, drives a selective translational regulation of transcripts necessary to reach final meiotic maturation.
Welfare Consequences of Sustainable Finance
Authors: Hong Harrison , Wang Neng , Yang Jinqiang 
Published: May 2023

Abstract
We model the welfare consequences of mandates that restrict investors to hold firms with net-zero carbon emissions. To qualify for these mandates, value-maximizing firms have to accumulate decarbonization capital. Qualification lowers a firm’s required return by its decarbonization investments divided by Tobin’s q, that is, the greenium or the dividend yield shareholders forgo to address the global-warming externality. The welfare-maximizing mandate approximates the first-best solution, yielding welfare gains compared to laissez-faire by mitigating the weather disaster risks resulting from carbon emissions. Our model generates optimal transition paths for decarbonization that we use to evaluate proposed net-zero targets.

Cardioprotective and Antianginal Efficacy of Nicorandil: A Comprehensive Review
Authors: Goel Harsh , Carey Matthew , Elshaikh Abdelsalam , Krinock Matthew , Goyal Deepak , Nadar Sunil K. 
Published: May 2023

Abstract:
Angina pectoris remains a significant burden despite advances in medical therapy and coronary revascularization. Many patients (up to 30%) with angina have normal coronary arteries, with coronary microvascular disease and/or coronary artery vasospasm being major drivers of the myocardial demand–supply mismatch. Even among patients revascularized for symptomatic epicardial coronary stenosis, recurrent angina remains highly prevalent. Medical therapy for angina currently centers around 2 disparate goals, viz secondary prevention of hard clinical outcomes and symptom control. Vasodilators, such as nitrates, have been first-line antianginal agents for decades, along with beta-blockers and calcium channel blockers. However, efficacy in symptoms control is heterogenous, depending on underlying mechanism(s) of angina in an individual patient, often necessitating multiple agents. Nicorandil (NCO) is an antianginal agent first discovered in the late 1970s with a uniquely dual mechanism of action. Like a typical nitrate, it mediates medium–large vessel vasodilation through nitric oxide. In addition, NCO has adenosine triphosphate (ATP)-dependent potassium channel agonist activity (KATP), mediating microvascular dilatation. Hence, it has proven effective in both coronary artery vasospasm and coronary microvascular disease, typically challenging patient populations. Moreover, emerging evidence suggests that cardiomyocyte protection against ischemia through ischemic preconditioning may be mediated through KATP agonism. Finally, there is now fairly firm evidence in favor of NCO in terms of hard event reduction among patients with stable coronary artery disease, following myocardial infarction, and perhaps even among patients with congestive heart failure. This review aims to summarize the mechanism of action of NCO, its efficacy as an antianginal, and current evidence behind its impact on hard outcomes. Finally, we review other cardiac and emerging noncardiac indications for NCO use.

Published: May 2023

Abstract

Purpose:
To describe new histological findings involving the inner retina in birdshot chorioretinopathy.

Methods:
Evaluation of the inner retinal pathology of the eye of a patient with bilateral birdshot chorioretinopathy who underwent enucleation for a unilateral ciliochoroidal melanoma.

Results:
Histopathological sections showed focal perivascular lymphocytic infiltration at the optic nerve head that extended into the adjacent inner retina, mainly involving the ganglion and nerve fiber layers.

Conclusion:
We have previously shown that birdshot chorioretinopathy has multiple foci of lymphocytes in the choroid. This is the first report that demonstrates lymphocytic infiltration of the inner retinal layers. This may lead to the bipolar and Muller cell dysfunction that ultimately results in an electronegative ERG.
