Published: September 2023

Consumption, which is an important need and a special variable in human life, often has negative implications when it is released without any regulation. The religious elements contained in it have provided limits for the creation of a balance of life. Namely the concept of halal and thayyib in food and drink according to Islam. So that a deep understanding is needed to educate through the interpretation of economic verses, especially about consumption. This paper seeks to explore the urgency of halal food and drink, which then makes it the basis and pattern of life for Muslims. By using the interpretation method to analyze the urgency, and provide a model in the education of halal food and beverages. Three patterns of implications for halal consumption trends have provided a balanced condition according to Islam. Namely first: objects that have become a trend to provide good habits, second: elements of benefit and benefits that exist in halal food and drinks, third: do not have a negative impact and harm to the body and soul. This paper also finds the term education which is the basic element of the halal trend in food and beverages.

Authors: Sri Astutik  , Irawan Soerodjo
Published: September 2023

The development of modern business in the digital era in the services of non-bank financial institutions, which provides convenience and acceleration in services to consumers of financial services is Financial Technology. Peer-to-peer lending is a fintech product that provides loans to debtors at high interest rates. The maximum loan interest rate set by the Indonesian Joint Funding Fintech Association (AFPI) is 0.8% per day. This determination is very burdensome for the debtor as a consumer of financial services, so there needs to be protection and regulation by the authorized institution. This normative legal research aims to determine the role of the Financial Services Authority in determining the Financial Technology Loan Interest Rate as the Protection of Financial Services Consumers. The results of this study, that the role of the Financial Services Authority as an institution that has the authority to regulate and supervise bank and non-bank financial institutions, has issued Financial Services Authority Regulation no. 77/POJK.01/2016 concerning Information Technology-Based Lending and Borrowing Services. In the POJK, OJK does not set loan interest rates. Peer-to-peer fintech lending providers are encouraged to offer reasonable interest rates and are still within a reasonable range.

Published: September 2023

Article 28H and Article 34 of the 1945 Constitution of the Republic of Indonesia stipulate that fulfilling the health rights of Indonesian citizens is the responsibility of the state. Human rights require that individuals have access to the availability of medicines in society. The high price of medicines, especially patent medicines, results in limited access and availability of essential medicines. This study uses normative legal research methods, with a statutory approach, and a conceptual approach. The purpose of this study is to examine and analyze the state's goals in fulfilling the right to health as a human right by the state as well as access and availability of patented drugs to fulfill the right to health. In addition to ensuring the availability of complete medicines in sufficient quantity, quality, affordable and easily accessible to the public, the government is also responsible for protecting the rights of inventors as long as the drugs are still under patent protection. To balance these two rights, the government plays the role of provider, regulator, entrepreneur and umpire.

Published: September 2023

Upstream oil and gas business activities are exploration and exploitation activities carried out by cooperation contract contractors ( KKKS) in a work area with a cooperation contract, which in this case uses the type of PSC. In a working space, a part of the field is not cultivated by KKKS, which is commonly called an Old Well. Factually Old Well management regulations still need amendments and updates to developments, especially in upstream oil and gas contracts, which have now been switched to gross split PSC. This study adopted a normative method, with data sources drawn from primary and secondary legal materials. Ultimately, it is appropriate and reasonable to amend the management of Old Wells, considering that upstream business activities continue to develop and undergo changes. Therefore, understanding the old well management scheme, in line with regulatory changes in upstream oil and gas business activities, is essential. Furthermore, until now, what is still used is the type of operating cooperation (KSO) for old well management, but basically, the appropriate cooperation contract model to be used in the direction of Old Wells that can meet the needs of all parties involved in the type of profit-sharing contract, while still meeting the minimum clause requirements that must be in the Old Well management contract following the operational procedure guidelines (PTK) for the management of Old Wells. In this regard, the government should consider using a gross split production-sharing contract (PSC) scheme to manage oil and gas wells in Old Wells.

Published: September 2023

In Malaysia, social enterprises (SEs) are still in their infancy, but they are growing in popularity as more people become aware of the beneficial effects on local communities. SEs in Malaysia are business models that combine the aspects of both non-profit and commercial entities to achieve social or environmental objectives. Business organizations, such as partnerships, corporations, and limited liability partnerships, are used to operate SEs because there is no specific legal entity for SEs in Malaysia. From a Malaysian perspective, tax-exempt status is one of the main challenges encountered by Malaysian social entrepreneurs. Despite the government’s efforts to recognize SEs, the problem of taxation for SE has not been resolved because SE still must pay taxes in a manner similar to that of commercial entities. This study aims to provide tax benefits to SE in Malaysia. Although Malaysia revised its laws and accredited SEs, no tax exemption has been provided exclusively for SEs. SEs contributions are meant to improve social welfare, but SEs are not exempt from taxes, such as charitable organizations. SEs business methods and organizational structures, which are comparable to those of commercial companies, lead to the conclusion that SEs are comparable to commercial organizations. The research concludes that by introducing tax exemptions permanently for SEs in Malaysia, customers can benefit from supporting businesses that align with their values, while SEs can benefit from increased support and growth opportunities. Governments can also benefit from a stronger economy and increased social and environmental impacts, making this an attractive policy option for Malaysian society.

Published: September 2023

This article that uses and is based on applicable laws and principles. The legal and regulatory approach is carried out by examining legal provisions, in particular, Law Number 11 of 2012 concerning the Juvenile Criminal Justice System, Law Number 35 of 2009 concerning Narcotics, and other related regulations to determine and find out the age of a child before the law. relevant in national criminal law. Based on the above approach, the results of the discussion of this study are: Children in conflict with the law are children who are 12 years old but have not reached the age of 18 who are suspected of committing a crime. This definition was derived from a law known as the Law on the Juvenile Criminal Justice System (UU SPPA), which replaced the law known as the Law on Juvenile Courts. As a result of this definition, it is clear that the Legislature has reached a consensus that the age of eight is an inappropriate age for a person to be held accountable for actions they have committed. In terms of handling narcotics cases, especially children as dealers, the prosecutor's attention is needed to better control the results of investigations conducted by the police so that they can catch perpetrators of child narcotics dealers to uncover a large network of narcotics dealers. Until now there has been no study or regulation that specifically regulates the prosecutor's authority to control the results of investigations by the police to be able to catch perpetrators of child narcotics dealers to uncover the large network of narcotics dealers behind them.

Deontología periodística digital: de los códigos de ética a la ética de la conversación
Authors: Crettaz José
Published: September 2023

Los códigos de ética siguen siendo referencia para todas las profesiones, también para el trabajo periodístico. Fueron una guía imprescindible durante muchas décadas y contribuyeron a la consolidación de la profesión y a la confianza ciudadana en la información pública. Pero su formato pétreo los hace poco versátiles en la era de la autocomunicación de masas, donde lasvoces profesionales comparten escenario con todas las demás y donde prevalece la desconfianza. En este nuevo contexto, se hace necesario repensar aquellos códigos e incorporar nuevas prácticas deontológicas, más inmediatas, flexibles y basadas en la conversación con las audiencias, a la vez fuente, destinatarias y verificadoras de la información.

Authors: Chen Qi , Chen Jie , Liu Yi-Ning , Qi Su-Hua , Huang Lin-Yan
Published: September 2023

Diabetes medication is based on controlling blood glucose and delaying the onset of related complications and is not a complete cure for diabetes. Conventional drug therapy fails to stop progressive islet β cell failure in diabetic patients. Recent studies have shown that "exosome-based therapy" holds great promise in treating diabetes and its complications. Exosomes are small vesicles that are stable in the bloodstream and can effectively deliver therapeutic drugs to specific tissues or organs through intercellular communication. Using exosomes as carriers for drug delivery offers several advantages. This review summarizes the benefits of exosomal drug delivery systems, drug loading methods, and their applications in treating diabetes and its complications. However, there are still challenges to overcome in using exosomal drug delivery systems, such as large-scale production, assessing the contents of exosomes, and monitoring the safety and effectiveness of the treatment in vivo. In conclusion, this review proposes the therapeutical potential of exosomes as drug carriers for developing novel drugs to provide new strategies for treating diabetes and its complications.

Herb cheese is cheese that contains herbs extracted for their antioxidant and bioactive properties. This study aims to determine the impact of adding herb leaf extracts to cottage cheese on its yield, composition, texture, and sensory characteristics. Three different herbs were used to prepare the extracts: bidara (Ziziphus mauritiana), moringa (Moringa oleifera), and bay (Syzygium polynthum). Cottage cheese was made in the the following process: cheese made of full-fat milk (FF), cheese made of low-fat milk (LF), cheese made of low-fat milk + 20%  bidara extract (LB), cheese made of low-fat milk + 20% bay extract (LS), cheese made of low-fat milk + 20% moringa extract (LM), cheese made of low-fat milk + 10%  bidara extract + 10% bay extract (LBS), cheese made of low-fat milk + 10%  bidara extract + 10% moringa extract (LBM), cheese made of low-fat milk + 10% bay extract + 10% moringa extract (LSM) and cheese made of low-fat milk + 6.67%  bidara + 6.67% bay + and 6.67% moringa extracts (LBSM). Each treatment was replicated three times. The variables included cheese yield, compositions, texture profile, and sensory characteristics. Herb extracts resulted in a slight variation in cheese yields ranging from 7.73 to 13.8%. Full-cream milk (FF) cheese contained the least moisture, while low-fat bay+moringa (LSM) cheese contained the most protein and the least fat. The texture profile showed a significant difference in hardness, cohesiveness, adhesiveness, gumminess, and chewiness but the springiness and resilience were similar. Herb extracts significantly contributed to the variation of sensory characteristics, including flavor, aroma, texture, and color. Adding herb extracts produces cheese with a slightly grassy aroma and bitter flavor. The addition of bidara, moringa, and bay leaf extracts during the manufacture of cottage cheese from cow milk resulted in the variation in yield, textures, composition, and sensory characteristics. Adding herbs produces cheese with higher moisture content but lower ash content than non-herb cheese. Cheese made with the addition of bay leaf extract had a higher hardness level than the control cheese and cheese added with other herbal extracts. The addition of herbal extracts makes a noticeable color change in cheese.

Exact Solution of Decaying Turbulence
Authors: Migdal Alexander
Published: September 2023

We have found an infinite dimensional manifold of exact solutions of the Navier-Stokes loop equation for the Wilson loop in decaying Turbulence in arbitrary dimension $d >2$. This solution family is equivalent to a fractal curve in complex space $\mathbb C^d$ with random steps parametrized by $N$ Ising variables $\sigma_i=\pm 1$, in addition to a rational number $\frac{p}{q}$ and an integer winding number $r$, related by $\sum \sigma_i = q r$. This equivalence provides a \textbf{dual} theory describing a strong turbulent phase of the Navier-Stokes flow in $\mathbb R_d$ space as a random geometry in a different space, like ADS/CFT correspondence in gauge theory. This is a \textbf{quantum} statistical system with integer-valued parameters, satisfying some number theory constraints. Its long-range interaction leads to critical phenomena when its size $N \rightarrow \infty$ or its chemical potential $\mu \rightarrow 0$. The system with fixed $N$ has different asymptotics at odd and even $N\rightarrow \infty$, but the limit $\mu \rightarrow 0$ is well defined. The energy dissipation rate is analytically calculated as a function of $\mu$ using methods of number theory. It grows as $\nu/\mu^2$ in the continuum limit $\mu \rightarrow 0$, leading to anomalous dissipation at $\mu \propto \sqrt{\nu} \rightarrow 0$. The same method applies to other observables. The small perturbation of the fixed manifold satisfies the linear equation we solved in a general form. This perturbation decays as $t^{-\lambda}$, where the anomalous dimensions $\lambda$ satisfy the spectral equation \eqref{spectralEq}. The spectrum becomes a continuum in the statistical limit $N \ra \infty$, leading to multifractal phenomena.

Published: September 2023

Caring for an ill or disabled relative can present significant challenges that may exceed the per-sonal resources of the caregiver. Young carers (YCs) often take on this role, providing support to family members or friends, which can have far-reaching effects on various aspects of their lives. This study involved 235 adolescents, 106 YCs and 129 non-carers (NCs), who completed ques-tionnaires assessing life satisfaction, social support, family functioning, academic functioning, and caring activities. Group effects measured with MANOVA and MANCOVA (controlling for age effects), showed YCs to have higher amounts of caregiving activities than NC (as expected) but lower satisfaction with life. Hierarchical regressions also found that, for YCs, academic func-tioning, social support and the negative impact of caregiving predicted satisfaction with life; and that the negative impact of caregiving on YCs is explained by their family functioning and the amount of their caregiving activities. For NCs, only academic functioning, social support and family functioning predicted satisfaction with life. In conclusion, caregiving has a negative im-pact on YC’s life satisfaction, but this effect is determined by their social support, academic func-tioning and negative impact of caring, which in turn depends on their familiar functioning and amount of caring activities.
Climate Change Impacts on the Density Altitude of Chinese Airports in Summer
Authors: Kang Xianbiao , Meng Zijing , Feng Wan , Liu Yunfeng
Published: September 2023

This study examines the projected impact of climate change on the Density Altitude (DA) at Chinese airports during the summer by the end of the 21st century. Findings indicate that climate change is expected to significantly increase the DA at all Chinese airports, with an estimated rise between 300 and 800 feet. The analysis suggests temperature increases will universally contribute to a rise in DA. Pressure changes, however, are more variable. Most airports are predicted to see an increase in pressure, which could offset some temperature effects on the DA. Airports in eastern China are expected to see a decrease in pressure, amplifying the effects on DA and creating operational challenges.

Conductive Polymers and a Method to Determine the Proton Conductivity of Polymer Membrane
Authors: Öztürk Raif
Published: September 2023

In this research the possibility of using pH change to measure proton conductivity of proton exchange membranes (PEM) or else known as polymer electrolyte membranes are tested with using an experimental setup prepared by using pH meters. PEMs are an important part of the fuel cells and proton conductivity of the PEMs are one of the most important properties of the PEMs. Also, proton conductivity is the one of the biggest limiting factors of fuel cells thus it is important to measure the proton conductivity of the PEMs while trying new polymers or new types of membranes. But as current measurement methods do not have a standard and can be separated into mainly two different measurement methods which are Electron Impedance Spectroscopy (EIS) and Ion Exchange Capacity (IEC). EIS gives clearer results, but it needs an impedance analyzer machine, platinum electrodes and setup so this cannot be possible for every researcher due to its economical aspect. For IEC it is basically a titration method to see acid groups in the polymer or polymer matrix which are directly responsible for proton conductivity so this can show an indirect measurement of proton conductivity. But as for this one drawback are firstly this one is an indirect measurement and secondly needs overnight bath in solution can take long times. So, the possibility of using pH can be easier and both from time and economical aspect if it can be proven the give a direct relationship between pH change and proton conductivity.

Role of Hydrogen Storage for UK Energy Resilience for Net Zero

This narrative document sets out, five steps, the main rationale for hydrogen storage development at scale in the UK: To meet net zero, the UK will need considerable energy storage:There will be significant periods of mismatch between renewable energy supply and energy demand, within-day, on cold winter weeks, and seasonally. And renewable energy constraint payments are forecast to rise to a peak of £1-2.5 billion a year in the mid-2020s.Energy storage at scale is therefore needed to maximise the energy recovery from the UK's vast wind and other variable renewable resources.Hydrogen storage will be a major and essential part of this:Of the main electricity storage options, batteries are short duration and not at sufficient scale, and there are limited new pumped hydro sites.Hydrogen production and storage can also offer a solution to electricity grid constraints, enabling more renewable capacity installation, and maximising the usage of that capacity, with lower curtailment.The recent Long Duration Energy Storage report for the UK Department for Net Zero and Energy Security (DESNZ, formerly BEIS) concluded that longer duration storage solutions reduce net zero system costs by £13-24 billion a year, and that the largest savings arise from a combination of hydrogen storage and hydrogen CCGTs.DNV's modelling for this project found that, to ensure continued energy provision in the coldest periods with very low wind generation (such as in early December 2022), hydrogen storage will range from 29-65 TWh – equivalent to 20-45 new salt cavern facilities with each facility comprising multiple individual caverns.Not surprisingly, scenarios with hydrogen heating require more hydrogen storage. But the electrified heating scenarios would require more electricity generation, storage and transmission infrastructure, which are not quantified here. These investments can be very large indeed. DNV recently carried out a study for Eurogas, looking at Europe as a whole, and found that in an electrification scenario, electricity transmission and distribution infrastructure investment would need to be €106 billion a year, compared with €63 billion a year in a balanced electricity and decarbonised gas scenario. A balanced scenario would therefore save €41 billion a year on power grids, with only an additional €2 billion a year needed for gas transmission and distribution infrastructure.

This paper presents an Artificial Intelligence (AI) based implementation for anomaly detection in critical industrial equipment at TotalEnergies. The approach was initially inspired by the work of Sipple, J. (2020), on AI anomaly detection in smart buildings. This approach has since then been adapted, applied, and extended to also handle multidimensional time series data effectively, whilst keeping model interpretability by design. The AI models have been successfully deployed in various North Sea assets and have been able to detect anomalous behaviour in the industrial rotating equipment, leading to improved visibility, efficiency, and reliability. The paper also discusses the motivations for the business case and change management processes associated with the implementation of the AI models.

Published: September 2023

This study provides an overview of the evolution of technology in the reservoir modeling field, discussing past, present, and future advancements. It explores how technologies such as central and graphics processing units have enabled engineers to increase the number of simulation grids from 500,000 to 1 trillion cells over the last 20 years. The paper also examines data-driven workflows that have accelerated the reservoir modeling process to a few weeks, highlighting their limitations. To address these limitations, the study introduces hybrid physics-guided data-driven models as a modern digital tool for mapping potential remaining oil in brownfields. These hybrid workflows combine the strengths of both physics-guided and data-driven models, overcoming the weaknesses of each approach. Two case studies, located in the North Sea and the Middle East, are reviewed to demonstrate the effectiveness of these hybrid workflows. The comparison of the water saturation map generated by the hybrid workflow with the contact movement calculated from 4D seismic data in the North Sea field shows a strong correlation, indicating a reliable match between the two maps. In the Middle East case study, the performance of four infill wells calculated by the hybrid workflow is evaluated against the actual outcomes of post-drilling activities. The results show that, except for one of wells, the actual outcomes align with the predicted trends, falling within the P10-P90 band. The paper emphasizes the novelty and benefits of using hybrid workflows, as they enable the generation of potential remaining oil maps in a few days—a task that is challenging with conventional numerical simulation workflows. These hybrid workflows offer significant time and cost savings while maintaining high fidelity. The advanced technologies discussed in this study facilitate the implementation of practical digitalization strategies across all disciplines in the industry, ushering in a new era of data-driven innovation.
Increased Efficiency on Plug and Abandonment Campaign Using New-Generation Ultrasonic Pulse-Echo and Pitch-Catch Configuration Technology

An operator on the Norwegian Continental Shelf oversaw the execution of a plug and abandonment (P&A) campaign comprising 32 wells in a mature field. The barrier evaluation plan was developed based on previous experiences in a field with similar properties and conducted by another operator that included the cement and solids evaluation using conventional ultrasonic technology. This paper describes how the introduction of the latest generation transducers aided in shortening the P&A campaign duration, saving days of rig time.

The entire logging plan for barrier evaluation within the32 well P&A campaign was custom developed, executed, and jointly analyzed by the operator and the service company. The logging intervals, well fluid and multiple casing size targets were considered during the strategic selection process. This enabled convergence to a solution that provided a comprehensive evaluation while avoiding multiple logging descents and achieving a faster acquisition speed without degradation of the results.

Acquisition capabilities have been constantly evolving over the past decades. The full data acquisition campaign described in this paper was improved from the original plan and adjusted to include a combination of ultrasonic pulse-echo and pitch-catch imaging measurements, third interface echo (TIE), an output of the pitch-catch method supported by and the traditional sonic technology response, enabling quick annular material identification as well as casing cut-and-pull decision making. The combination of all measurements allowed a robust solution that is independent from wellbore logging fluid and potentially unknown annular materials that segregates or changes through the life of these wells. The technology blend adopted in this field enabled a direct logging time reduction of 50% and allowed the acquisition of multiple nonconcentric casing sizes in a single descent, which is not possible with previous generation technologies. The overall result helped the operator to reduce their greenhouse gas (GHG) emissions during those operations by shortening the barrier evaluation campaign length by 10 rig days.

The operator was able to significantly reduce the rig time spent in the campaign the implementation of the latest ultrasonic barrier evaluation logging technology, thus reducing their overall GHG emissions without compromising the results of the original objectives.
