Abstract

PT. Perintis Makmur Indonesia (PMKI) is a smelting company that plays an important role in workforce absorption in the Morowali area. In particular, the mechanical department, consisting of 18 employees, requires an upgrade in pipe welding skills using the SMAW welding method. This is due to the fact that the mechanics are currently only capable of performing plate-to-plate welding, whereas they are required to have pipe-to-pipe welding skills to support their work. To enhance its employees' competencies, particularly in pipe welding, PT PMKI collaborated with the Morowali Metal Industry Polytechnic to organize a Shielded Metal Arc Welding (SMAW) training program for its employees. The primary goal of this training was to improve the employees' skills in performing pipe welding safely and efficiently. The training methods included lectures, discussions, and hands-on practice in the workshop, along with evaluations through pre-tests and post-tests. A total of 18 mechanics participated in this fiveday training. The materials covered welding safety, SMAW techniques, and defect handling in welding. The results showed a significant increase in participants' understanding and skills. The initial understanding level, as measured by the pretest, was only 19.8%. After the training, participants' understanding increased to 93.2%, as indicated by the post-test results. This training successfully improved the employees' pipe welding competencies, which are crucial for supporting the company’s operations.

Abstract

Islam is the most perfect religion. One of the perfections of Islam is to oblige all Muslims to earn a lawful living by working or doing business in the right way. Islam not only teaches to worship, but Islam also teaches its people to be independent and work hard. One of them with entrepreneurship or Entrepreneurship. This paper aims to see that the importance of having an entrepreneurial character is seen from the nature of entrepreneurship, how the character of entrepreneurship is from an Islamic point of view, then wants to see the supporting factors and driving factors for entrepreneurial activities for the advancement of economic development in Indonesia. This study collects as much data as possible from primary data sources, namely entrepreneurship books. And secondary data in the form of journals and books that discuss entrepreneurial theory from an Islamic perspective. The technique of data analysis is done by annotated bibliography analysis (annotated bibliography) which means a simple conclusion from an article, book, journal. Entrepreneurship according to Islamic teachings is a job that requires hard work. While working hard is an obligation for every Muslim. The entrepreneurial character in Islam is taqwa, honest and trustworthy, prioritizing the concept of halal, the command to work hard. The driving factors for entrepreneurship are having the ability and willingness, strong determination and hard work, opportunities and opportunities.

Abstract

This study takes a multicultural approach to the concept of Islamic religious education. Differences are unavoidable in a world that is rapidly evolving as it is today. Often, acts of violence, whether in the form of group sarcasm in religious social life or through differences, do not need to occur. Islamic religious education, as part of religious education in schools, is thought to have helped children overcome this from an early age. This study employs library research to develop a theoretical framework and present the data using descriptive qualitative methods. The findings of this study show that multicultural education for students begins at a young age and is critical in developing an understanding of what differences are and how to respond to them. Accordingly, multicultural Islamic religious education aims to develop students with moral values such as love, assistance, forgiveness, tolerance, respect for differences of opinion and religious beliefs, and other attitudes capable of and supportive of human life harmony.

Abstract

Cocoa is a highly valued plant due to its versatile uses, including being processed into cosmetic products. Hair loss and slow hair growth are common hair-related concerns that can be effectively addressed through the use of hair tonics. Previously, research has shown that cocoa bean can effectively stimulate hair growth when made into a cream. Our research aimed to determine the secondary metabolite content of cocoa beans extract, formulate the extract into a hair growth tonic, and test its physical stability and effectiveness on hair growth in mice. Cocoa beans extracted by maceration method and conducted phytochemical screening. This extract was then used to create three formulations with different extract concentrations of 0.2%, 0.3%, and 0.5%, which were tested for physical stability, including organoleptic properties, homogeneity, pH, and specific gravity. Mice were divided into five treatment groups, hair length growth measurements were taken every week, on the 7th, 14th and 21st days. Six strands of hair were taken from the application area, and their length was measured using a calliper. Results revealed that cocoa seed extract contains flavonoids, alkaloids, tannins, and phenolics. The formula with a 0.3% concentration of cocoa bean extract showed the best physical stability. Hair growth tests on mice showed no significant difference between the 0.3% and 0.5% cocoa bean extract formulas and the positive control in the second week. The 0.3% formula is the best for ensuring good physical stability and promoting hair growth in mice when used twice daily for two weeks

Abstract

This research aimed to evaluate how enhancers affect the properties of Syzygium aromaticum oil in both water-soluble and hydrocarbon bases. Physical and chemical characteristic tests, irritation index evaluations, and anti-inflammatory activity assessments were carried out to analyze the Syzygium aromaticum oil ointment. The pH tests were conducted to measure the chemical characteristics and viscosity, adhesivity, spreadability tests were conducted to measure the physical characteristics of the ointment. Rabbit-based tests were used to determine the irritation index, mice induced by crotton oil were used in anti-inflammatory activity assessments. The pH tests revealed no significant differences between both of ointments. The ointment in the water-soluble base had higher viscosity and adhesivity but lower spreadability than the ointment in the hydrocarbon base. The epidermis thickness of watersoluble and hydrocarbon-based ointments was 3.81±0.40 μm and 4.22±0.15 μm, while the number of cells with COX-2 expression was 18.24±6.51 and 21.01±5.96. The addition of enhancers did not cause any irritation in either ointment. The study concluded that the formula of Syzygium aromaticum oil in a water-soluble ointment with the addition of propylene glycol and oleic acid (70:30) as enhancers provided better physical and chemical characteristics, a lower irritation index, and higher anti-inflammatory activity compared to the hydrocarbon.

Abstract

Polygamy is a term that contains various meanings, often exciting men's imaginations as an ideal while triggering deep emotions in women. Many women, naturally jealous and reluctant to share their husband's love, oppose polygamy. Despite this, some extraordinary women accept it patiently. On one side, critics link polygamy to gender inequality and discrimination against women, while supporters believe it can reduce infidelity and prostitution. Misconceptions about polygamy, often fueled by anti-Islamic sentiment, have influenced Muslim society, leading some to view it negatively and others to defend it as a part of Islamic perfection. This research then aims to find out how orientalists criticize polygamy law and refute orientalist understanding of polygamy law. This research method will be carried out using a qualitative approach. The data used in this research comes from the results of a literature study of previous literature and research that is still relevant. The results of this research then found that the polygamy law in Islam has a strong historical basis, aiming to protect and regulate the practice of polygamy with the principles of justice and responsibility. Islam sets strict limits and conditions to ensure that polygamy is not abused and that women's rights are protected. Misinterpretations by Orientalists often ignore this context and spread biased views regarding polygamy law. Despite challenges and criticism of the practice of polygamy, education and fair enforcement of the law can provide significant social and individual benefits.
