This study aimed to screen different solvents (ethanol, ethyl acetate, and n-hexane) of Coelarthrum muelleri for secondary metabolites and subject them to physicochemical analysis, including ash, swelling index, pH, and color tests with different reagents. Seaweeds have been recognized in the pharmaceutical industry for their broad spectrum of structural diversity and wide range of pharmacological activities for health and disease management. Coelarthrum muelleri from red algae was taken as a sample for this study. It was collected from the coastal range of Buleji and Kakapir beaches in Karachi, Pakistan. Three extracts of Coelarthrum muelleri (ethanol, ethyl acetate, and n-hexane), depending on their polarity, were subjected to phycochemicals of ten chemical compounds (glycosides, quinones, phenols, coumarins, steroids, alkaloids, saponins, flavonoids, terpenoids, and tannins) and physicochemical test for ash value, pH value, and swelling index. The dried powder of Coelarthrum muelleri was tested for color identification with eight other reagents. The preliminary phycochemical screening of Coelarthrum muelleri showed the presence of terpenoids, steroids, tannins, saponins, phenols, coumarins, glycosides, and quinones and the absence of alkaloids. Among three extracts, ethanol and ethyl acetate extracts show all compounds present except alkaloids. Next, n-hexane showed all compounds positive except for alkaloids, saponins, and quinones, which were absent. The physicochemical indicators are 38 ml of the swelling index, 2.3 pH of 1% Coelarthrum muelleri, and 3.16 pH of 10%. The total ash value is 24.86 + 0.15%, 8.4 + 0.1% for acid insoluble ash, and 7.1 + 0.1% for water-soluble ash. This study on the present seaweed will be helpful in the identification of secondary metabolites as well as be valuable for authenticating the purity and quality.


Keywords: adulteration, secondary metabolites, phycochemicals, seaweed, Coelarthrum muelleri.

In orthopedics, increasing the implant lifetime minimizes the need for repair surgery, which benefits the patient’s health and the practice bottom line. The quality of the materials and designs is always being enhanced to reach the ultimate objective of a single implant that would last a person their whole life. The purpose of orthopedic treatments is to enhance the patient’s ability to participate in normal activities and socialize, and the implant carrier should not be subjected to unnecessary limitations. As a result, implants are exposed to severe mechanical stress and the inherently hostile in vivo biochemical environment, which is particularly prevalent in younger and more active people. The development of hip prosthesis design and materials has taken this path in recent years. This development is one of the most challenging problems in the field of implant technology in this century. In this study, various materials, including ceramics, glass, metal alloys, polymers, metal alloys, composites, and others, were used in an effort to combine biocompatibility with fatigue resistance, stiffness, hardness, the capacity to withstand dynamic and static stresses, and excellent chemical and mechanical wear resistance. The fracture toughness of zirconia-toughened alumina composites is increased by a factor of four compared to alumina by itself. Zirconia was first included in alumina as a densifier; however, it was not until much later that zirconia was used as a reinforcement particle to increase the level of toughness in the material. The use of ZTA to improve the mechanical properties of orthopedic implants has lately been the subject of several studies, which have all just been concluded. This research includes a literature review primarily concerned with the Biolox Delta composite, its microstructural properties, manufacturing and prosthesis materials for it to identify as a bioceramic material for medical applications.


Keywords: Biolox, composites, orthopedics, hip.

This study aims to examine the determinants of entrepreneurial learning that depend on entrepreneurial intentions in college students in Lampung, Indonesia. The survey was born with an online questionnaire from June until July 2021. Data were processed using SmartPLS 3.2.7. The data analysis found significant direct and indirect effects. The constructing indicators can predict latent variables with a recommended value of more than 0.7. We also found that this research contributes additional conceptual framework theories for lecturers teaching entrepreneurship learning and decision-makers in universities to focus more on developing entrepreneurship education curricula.


Keywords: predicting, entrepreneurship learning, factors, entrepreneurial intent, student universities.

Managing companies’ integral functioning today is a challenge that should not be isolated since external dynamics require immediate responses to customers’ needs. This article aims to generate a proposal for an organizational management model for manufacturing companies in the state of Hidalgo, Mexico. In addition to serving as a tool to achieve competitiveness, it provides integral development and in turn generates a regional development that can be expanded. A methodology with a quantitative, descriptive and explanatory approach was used, by collecting information from 239 economic production units with more than 11 employees in their workforce, to which questionnaires were applied by electronic means. This request was addressed mainly to the managers, supervisors and owners of the organizations, then the information was codified, processed and analyzed. The results evidenced that the organizational management should be composed of twelve of the 20 possible elements: market management, operations, financial, knowledge and human resources, innovation, corporate social responsibility, environmental analysis, strategic management and, finally, trade and sales. It was considered that the above-mentioned elements formed the econometric model that these variables explained organizational management by 92 per cent, according to the value obtained by R-squared adjusted with a value of 0,928210. Therefore, it is presented as a feasible proposal for application in manufacturing companies which can gradually increase their competitiveness influencing development.


Keywords:  econometric model, organizational management, manufacturing companies.

Until now, there has been no specific regulation regarding the crime of political corruption in the laws and regulations in Indonesia, but this kind of activity has become familiarly mentioned. This phenomenon makes the legal position of the criminal act of political corruption worthy of being a separate offense in a material criminal law regulation. The purpose of writing this article is to determine the legal position which can later be used as material to formulate a new criminal act in the form of political corruption in the applicable positive law. This article uses the normative juridical research method through statute approach, comparative approach, and conceptual approach, which aims to critically examine the legal position of the criminal act of political corruption as part of the reflection of money politics practices. The study results indicate that in the context of future legal reforms, money politics as a form of political corruption must be regulated as a special offense in the law on eradicating corruption. The novelty offered by the authors in this article is the idea of the need to criminalize political corruption as a separate crime in the future.


Keywords: democracy, political corruption, general election, money politics, crime.
