A lopography or barium enema colostomy is a radiographic examination of the colon using a contrast medium inserted through a colostomy. This examination aims to evaluate the condition of the colon after the colostomy, including detecting the presence of obstructions or masses in the gastrointestinal tract. The contrast medium used is a type of non-ionic soluble water that is inserted through the stoma and anus orifice until it fills the entire colon, characterized by the exit of contrast through the stoma. The examination was carried out using several radiographic projections, including plain photographs of the AP abdomen, as well as post-contrast projections of the Antero Posterior (AP), Right Posterior Oblique (RPO), Left Posterior Oblique (LPO), and lateral. This study aims to find out the procedure for the Lopography examination at the Radiology Installation of Caruban Hospital and the medical reasons for the use of two channels of input of contrast media, namely through the stoma and anus. The method used is qualitative descriptive research with a case study approach. The study was carried out from November to May 2025, with one post-colostomy patient as a sample. Data collection was carried out through direct observation, interviews with medical personnel, and documentation of radiographic procedures. Data analysis includes data reduction, data presentation, and conclusion drawn. The results of the study showed that the procedure of Robotic examination did not require any special preparation before the procedure. The non-ionic contrast medium used is mixed with aquades at a ratio of 1:3 (about 200 cc), and inserted through both the stoma and the anus to obtain a thorough visualization of the colon. The selection of two input paths aims to ensure that there are no blockages or masses that block the contrast flow. The projections used are adjusted to provide maximum information about the structure of the colon after colostomy

This community service activity was carried out with the aim of improving the memory of students at the Baiturrahman Islamic Boarding School (TPQ) through the implementation of group guidance based on an interactive question and answer method. The background of this program is based on the problem of low retention of religious material that has been learned by students, so the learning approach is needed that does not only emphasize memorization, but also activates the process of critical and in-depth thinking. In its implementation, the activity is designed to involve students directly in group discussions guided by a facilitator. The questions posed are structured in such a way as to stimulate repetition of information, encourage logical reasoning, and help students connect the learning material with real experiences in everyday life. Through this process, students are not only asked to answer questions but are also trained to develop broader answers, thereby strengthening understanding and improving communication skills. This program also prioritizes a fun, collaborative, and participatory learning atmosphere so that students feel more motivated to actively participate. Evaluation results show a significant increase in students' ability to remember, understand, and re-present learning material more quickly, accurately, and coherently. Furthermore, this activity also has a positive impact on increasing students' self-confidence in the learning process and strengthening collaborative skills among group members. Thus, group guidance using the question-and-answer method can be considered an effective learning strategy for strengthening students' memory and increasing their learning motivation.

The development of hardware and software technology has developed rapidly in recent years. Currently, companies are still experiencing difficulties in processing data and information. Spare parts that are not available when needed can hinder maintenance and repair plans. For this reason, controlling spare parts inventory in the Asia Jaya Motor workshop company is very necessary to maintain the quality of goods. Asia Jaya Motor Workshop is a business operating in the automotive sector, where this place cannot be separated from an accurate information system. However, data management still uses manual methods, seeing the problems that occur at the Asia Jaya Motor Karawang Workshop, very high accuracy, convenience and speed are needed. The aim of this research is to obtain an effective and efficient spare parts inventory analysis so that spare parts procurement and control plans can be accurate in supporting maintenance and repair programs. The data collection techniques for this research are library research and field research. So, the total cost of spare parts inventory in the 2011-2014 period according to the Economic Order Quantity method for each spare part has increased. The total cost (total cost) of spare parts inventory according to the Economic Order Quantity method is lowest in the 2021 period and the total cost (total cost) of spare parts inventory is the highest in the 2023 period.

Public transportation is one of the needs that must be met for every human being who carries out daily activities, so the government needs to pay attention to its development. The city of Surabaya is one of the cities with high traffic jams, which is one of the reasons for developing public transportation. Wira Wiri Suroboyo, which was inaugurated last year, brought enthusiasm from the public but also experienced a decline in passengers in the second month of its launch. The explanation explained by the Transportation Service regarding the decrease in the number of passengers is that it coincides with the fasting month which means not many people travel. However, if compared with the number of people in Surabaya City, the use of Wira Wiri Suroboyo transportation is still not fulfilled. Public interest in using public transportation is considered lacking. This research was conducted to determine the success of implementing public transportation development policies through the Wira Wiri Suroboyo program. This research uses qualitative methods with observations at the Transportation Service through interviews and taking documentation. The results of this research are that the implementation of public transportation development through Wira Wiri Suroboyo can be said to be successful, seen from the increase in the number of passengers.

The digital age has brought significant transformations to various sectors, including religious scholarship, where traditional structures of authority are being challenged by the rise of digital media and influencers. This study explores the implications of digital disruption in the Islamic context, focusing on how digital platforms are reshaping authority and epistemic legitimacy. In particular, the emergence of "religious digital creatives" is analyzed, highlighting how these influencers, often with little formal training but significant digital communication skills, have redefined religious authority. This shift away from traditional scholars, such as the ulama, who have been the custodians of religious knowledge, raises concerns about the authenticity and quality of religious teachings disseminated online. The study also examines the role of algorithm driven platforms, like AI-driven tafsir apps, and their impact on Islamic legal derivation and interpretation. While these platforms enhance accessibility, they also present challenges related to standardization and authenticity. By comparing traditional Islamic epistemology, which balances divine revelation, human reason, and scholarly rigor, with the decentralized authority of digital platforms, the study underscores the need for maintaining scholarly integrity and moral responsibility in the digital era. The research also highlights the importance of community trust in traditional scholarship, which is undermined by the lack of accountability in digital content. Ultimately, this study provides a framework for understanding the evolving relationship between Islamic epistemology and digital media, offering recommendations for preserving the core values of traditional scholarship while embracing the opportunities of digital innovation.

The Unnoni Weaving Center is a community-led, small and medium-sized enterprise (SME) development center for traditional weaving. Despite its significant potential, many entrepreneurs in this center face challenges in determining appropriate product prices. They typically rely solely on intuition or follow market prices without considering all production cost components, resulting in very small profit margins and even the risk of incurring losses. In response to these challenges, this community service program was designed to improve the ability of SMEs to determine more rational, measurable, and profitable selling prices through comprehensive and applicable training in production cost calculations. The methods employed included outreach, workshops, intensive mentoring, and hands-on simulations on pricing based on real costs and reasonable margins. The program was conducted in two sessions at the Unnoni Weaving Center Hall, involving 25 local weaving entrepreneurs. The results showed significant improvement, with participants' understanding of identifying production cost components increasing by 76%, while approximately 80% successfully conducted simulations for determining selling prices, taking into account raw materials, labor, overhead costs, and profit margins. The tangible impact of this activity is seen in increased business literacy, more systematic calculation skills, and the confidence of SMEs in determining prices and negotiating with consumers and business partners. Furthermore, this activity is expected to be a starting point for the implementation of a simple financial recording system, increased operational efficiency, and the development of a branding strategy for Unnoni woven products so they can compete more professionally, sustainably, and with high competitiveness in both local and global markets.

This study aims to describe the mathematical literacy skills of vocational high school students in solving statistics problems with the help of Microsoft Excel based on digital literacy levels, which are grouped into high, medium, and low. The background of this study is based on the importance of mathematical literacy in dealing with everyday problems and the demands of the world of work, as well as the increasing need for digital literacy mastery in the information technology era. Both are essential competencies that support each other, especially in technology-based mathematics learning. The research approach used is descriptive qualitative with a purposive sampling technique, where the selection of subjects is based on the results of the digital literacy questionnaire, equivalence of mathematics scores, and adequate communication skills to support the interview process. The research instruments include a digital literacy questionnaire, a mathematical literacy test in the form of descriptive questions completed using Microsoft Excel, and interview guidelines that have been validated by experts. The data collection procedure was carried out through tests and in-depth interviews, while data analysis included the stages of data reduction, data presentation, and drawing conclusions. The results of the study indicate differences in students' mathematical literacy skills based on their digital literacy levels. Students with high digital literacy are able to master mathematical literacy indicators well, including communication, mathematization, problem-solving strategies, and reasoning and argumentation. They can optimally utilize Microsoft Excel features to present data, perform calculations, and draw logical conclusions. Students with moderate digital literacy demonstrate fairly good mastery, but still experience difficulties in aspects of problem-solving strategies and in-depth reasoning. Based on these findings, it can be concluded that digital literacy plays a crucial role in supporting students' mathematical literacy abilities.  

This study aims to determine the influence of the Time Token Learning Type learning model combined with science literacy on communication skills and cognitive learning outcomes of SMPN XYZ students. The background of this research is low communication skills and student learning outcomes that are still substandard, so an innovative learning approach is needed that can improve both aspects. The research method used was quasi experimental with a Pretest-Posttest Control Group Design. The research subjects involved one experimental class given Time Token Learning type learning with science literacy content and one control class that used conventional learning. The research instrument consisted of a reasoned multiple-choice test to measure cognitive learning outcomes and an observation sheet to assess communication skills. The results of the study show that the application of the Time Token Learning model with science literacy has a significant influence on improving students' cognitive learning outcomes. The average pretest score of 40 increased to 75 in the posttest with an N-Gain value of 45.5% which was in the medium category. These findings prove that the learning model is effective in improving students' understanding of concepts and cognitive thinking skills. However, the results of the analysis of communication skills did not show a significant improvement. In addition, the correlation between communication skills and learning outcomes was also insignificant with a significance value of 0.826 > 0.05. In conclusion, the Time Token Learning model with science literacy has proven to be effective in improving students' cognitive learning outcomes, but has not been able to optimally develop communication skills. Therefore, it is necessary to develop additional strategies or a combination of other learning models so that communication skills can develop in line with improving cognitive learning outcomes.

Criminal liability, also known as "criminal responsibility," is a legal assessment that is made after all elements of a criminal act are met or evidence of a criminal act is proven. The purpose of this assessment is to determine whether the defendant can be held accountable for the criminal act committed. This study specifically focuses on criminal liability for the perpetrator of murder who is a person with paranoid schizophrenia, as well as the factors that influence the act of murder. The approaches used in this study are normative juridical and empirical juridical juridical The research involved the Judge of the Gedong Tataan District Court and a Psychiatrist at the Regional Psychiatric Hospital of the University of Lampung as the main speakers. Data collection was carried out through literature studies and field studies to obtain a comprehensive picture related to the legal, medical, psychological, and social aspects of the case being studied. The results of the study show that the defendant, even though it is legally proven that he committed a criminal act as stated in Decision No. 105/Pid.B/2023/PN.Gdt, is bound by the provisions of Article 5 letter a juncto Article 44 Paragraph (3) of Law Number 23 of 2004 concerning the elimination of domestic violence. However, based on judicial, medical, and psychological considerations, the defendant cannot be criminally held liable for his actions for excused reasons related to mental disorders. Factors that affect this act of murder include psychological aspects, psychological conditions, mental health, traumatic experiences, and the social and family environment in which the perpetrator grew up. The analysis shows the importance of an integrative understanding between criminal law, psychiatry, and social conditions in determining criminal liability.

This study aims to describe the social transformations found in the literary aspects of the Advanced Indonesian Language Textbook for grade 11 and analyze its relationship to the construction of the Pancasila Student Profile (P5). The main focus of this study is to examine how the literary works presented in the textbook function not only as a medium for language learning but also as a vehicle for character development and social understanding for students. This study uses a descriptive qualitative approach with sociological literary analysis techniques, where data is obtained from excerpts from poetry, short stories, and plays that depict social change. The results indicate that the social transformations reflected in these literary works are divided into two main forms: collective behavior and social movements. Collective behavior is demonstrated through themes of fashion and fashion, urban legends, and the phenomenon of mass hysteria, which implicitly depict social conflict, class inequality, and the dynamics of societal culture. Meanwhile, social movements are depicted in the narratives of characters who fight for change against norms, traditions, and social structures that limit freedom. This representation demonstrates resistance, critical awareness, and a drive towards a more just and equal life. The findings of this study are closely related to the dimensions of the Pancasila Student Profile, such as critical reasoning skills, a spirit of mutual cooperation, an attitude of upholding social justice, and independence in thought and action. Therefore, it can be concluded that literary works in Indonesian language textbooks not only present aesthetic value and literary appreciation, but also serve as an effective means of instilling national values and supporting the formation of student character in accordance with the vision of Pancasila.  

This study examines legal deviations in the implementation of the Suspension of Debt Payment Obligations (PKPU) mechanism, specifically regarding the approval of a peace settlement submitted for the second time after the debtor is declared bankrupt. The study highlights the Supreme Court Decision No. 648K/Pdt.Sus-Pailit/2021, which ratified the second peace settlement in the case of PT Prospek Duta Sukses. This decision is deemed contradictory to the principle of a single peace settlement, as stipulated in Articles 289 and 292 of Law No. 37 of 2004 on Bankruptcy and PKPU, and further reinforced by Supreme Court Circular Letter (SEMA) No. 5 of 2021, which states that a peace settlement in bankruptcy can only be conducted once. Using a normative juridical method, this research analyzes the legal reasoning used by the panel of judges in approving the second peace settlement and evaluates its impact on legal certainty and protection for creditors, who are the affected parties in the bankruptcy process. The approval of a second peace settlement after the debtor is declared bankrupt creates legal uncertainty, as the existing provisions do not provide for more than one peace settlement. Additionally, this decision potentially harms creditors by prolonging the settlement of debts, which should have been clear, thus allowing room for misuse of legal procedures. The findings of the study show that the approval of this second peace settlement not only contradicts the fundamental principles of law but also risks harming creditors, who should be protected by the bankruptcy system to ensure their rights are fairly met. Therefore, this research suggests that consistent application of the law, in line with existing provisions, is necessary to uphold the principles of justice, legal certainty, and the credibility of the national bankruptcy system. Furthermore, reforms in regulations or law enforcement are needed to ensure that legal practices operate in accordance with principles that are fair and transparent.

Breast carcinoma, commonly known as breast cancer, is a type of malignancy that occurs in the milk-producing ducts and sacs of the breast. Breast cancer is the second leading cause of death in Indonesia, after lung cancer. One of the early steps in detecting breast cancer is through breast self-examination (BSE). Although BSE can help detect lumps or abnormalities in the breast, many adolescent girls are unaware of how to perform this examination or its importance. One reason for this is the lack of education regarding the correct method and the significance of performing BSE regularly. Therefore, an effective educational approach is needed, such as peer education, where peers provide information to their fellow students about the importance of self-breast examination. The purpose of this study is to analyze the impact of a peer education program on improving adolescent girls' knowledge of BSE. This research uses a quantitative method with a quasi-experimental design, specifically a one-group pretest-posttest design. The population in this study consisted of female students from grades X and XII at SMK Nurul Islami Semarang, with a sample of 35 students selected through simple random sampling. Data collection was carried out using a questionnaire that included questions about the students' knowledge of self-breast examination. The results were analyzed using the Wilcoxon test, which showed an Asymp Sig (2-tailed) value of 0.000, which is smaller than 0.05. This indicates that the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted, meaning there is a significant effect of the peer education program on increasing adolescent girls' knowledge of BSE. The findings of this study suggest that peer education is an effective method for raising awareness among adolescent girls about the importance of early breast cancer detection, thus encouraging them to perform self-breast examinations more regularly.

This study aims to describe students' critical thinking skills in solving social arithmetic problems based on the Polya stages and FRISCO indicators. The research subjects consisted of three students in grade VIII R-5 MTs Nurul Jadid who were purposively selected to represent the high, medium, and low ability categories out of a total of 21 students. The research method used was a descriptive qualitative approach with instruments in the form of two social arithmetic description questions and semi-structured interview guidelines. Data analysis was carried out by referring to the four stages of problem solving according to Polya (understanding the problem, planning the solution, executing the plan, and re-examination) as well as the six FRISCO critical thinking indicators (Focus, Reason, Inference, Situation, Clarity, Overview). The results of the study showed that students with high abilities were able to solve problems systematically through all stages of Polya and met almost all FRISCO indicators, especially in the aspects of Focus, Reason, and Clarity. Students with moderate ability show sufficient understanding but are inconsistent in planning and implementing solutions, and experience difficulties in the Reason, Situation, and Overview indicators. Students with low abilities experience obstacles from the early stages of understanding problems and do not show significant indicators of critical thinking. These findings indicate that the Polya stage and the FRISCO indicator can be used in a complementary manner to identify and analyze students' critical thinking skills in solving contextual math problems. The implication of this study is the need for a learning strategy that emphasizes strengthening the stages of problem solving and developing explicit critical thinking indicators in the mathematics learning process. This research also opens up opportunities for the development of more structured diagnostic instruments in measuring students' individual critical thinking skills.

Happiness is the ultimate goal of every human aspiration. To achieve it to the fullest, humans strive to utilize all their potential. However, in practice, conflicts often arise between personal interests and the interests of others. The desire to realize all dreams becomes problematic when carried out without regard for moral values, especially in a household life built through the sacred bond of marriage. Many married couples fail to create domestic happiness due to uncontrolled ambition. This ambition, when not balanced with ethics and morals, has the potential to cause domestic conflict that results in the neglect of children's education in the family. A current widespread phenomenon shows that married couples spend more time outside the home for work reasons. This opens up opportunities for promiscuity in public spaces and reduces attention to family. If this phenomenon continues, serious problems in the family will become increasingly apparent. The rights and obligations of husband and wife are neglected, affection for children is diminished, and ultimately children feel more comfortable seeking environments outside the home. This condition becomes the entry point for negative speculation from society about married couples who are considered negligent in their household obligations. This research is expected to provide a significant contribution to understanding how families should function optimally. By placing religion as a foundation and making ethics and morals the foundation of social interactions, families can return to their true nature as the birthplace of quality generations with character, ethics, and spiritual values.  

This study aims to examine the influence of price, promotion, and product quality on the repurchase intention of Kopi Kenangan products among students of the Faculty of Social and Political Sciences, Mulawarman University. The research focuses on how effective marketing strategies can foster customer loyalty toward local coffee brands. The theoretical framework is based on the marketing mix, consumer decision-making processes, and indicators of customer loyalty. The study employs a quantitative research method, with data collected through questionnaires distributed to 100 respondents. The respondents were selected using purposive sampling, based on specific criteria determined by the researcher to ensure they could provide relevant information aligned with the research objectives. Data analysis was conducted using multiple linear regression with SPSS version 26. The findings indicate that price, promotion, and product quality each have a positive and significant effect on repurchase intention. Among these factors, product quality exerts the strongest influence, followed by promotion, and finally, price. These results suggest that enhancing product quality, implementing effective promotional strategies, and maintaining reasonable pricing can significantly increase customers’ likelihood of making repeat purchases. Based on the results, this study recommends that Kopi Kenangan continue to prioritize maintaining high and consistent product quality, as it plays a crucial role in shaping repurchase intentions. Additionally, promotional efforts should be continuously optimized to attract and retain customers in an increasingly competitive coffee market. Pricing strategies should also be monitored to remain competitive while ensuring profitability. Overall, the study concludes that product quality, supported by strategic promotions and competitive pricing, is essential for building and sustaining customer loyalty. By focusing on these factors, Kopi Kenangan can strengthen its market position and foster long-term relationships with its customers

Electronic commerce (e-commerce) has become a dominant trend in modern buying and selling transactions, offering easy access and efficiency. Marketplaces like Shopee act as intermediaries between merchants and buyers, providing fast, secure, and integrated transaction facilities. However, behind this convenience, significant legal issues arise, particularly regarding unilateral transaction cancellations by buyers through the refund feature. In practice, these refund requests are generally approved by the marketplace without thorough verification of the validity of the cancellation reason or the existence of the goods already shipped by the merchant. This study aims to analyze the legality of unilateral cancellations by buyers from the perspective of Indonesian civil law, with reference to the provisions of the Civil Code (KUHPerdata) and the concept of electronic contracts as stipulated in the Electronic Information and Transactions Law (UU ITE). The study uses a normative juridical approach by examining laws and regulations, legal literature, and analyzing two case studies involving merchants BZS and HK. The results indicate that unilateral cancellations by buyers without returning the goods constitute a form of breach of contract. This action not only violates the electronic contractual agreement established during the transaction but also causes financial and reputational harm to merchants. This phenomenon indicates weak legal protection for business actors in the e-commerce ecosystem, particularly regarding the bargaining power between sellers, buyers, and marketplace platforms. Therefore, strengthening fair and transparent digital dispute resolution mechanisms is necessary, including preventive legal protection to prevent losses and repressive protection to provide redress for injured parties. This step is crucial for realizing a healthy, balanced, and equitable digital trade ecosystem for all parties involved.

This study aims to determine the role of parents in fulfilling the right to education for girls based on the implementation of Article 31 Paragraph (1) of the 1945 Constitution in the region. This study uses a qualitative descriptive approach with data collection methods in the form of interviews, observations, and documentation. Informants in this study consisted of village heads, parents, and girls who dropped out of school. Data analysis was carried out using the interactive model of Miles and Huberman which includes data reduction, data presentation, and drawing conclusions. The results of the study revealed that some parents showed a high awareness of the importance of education for girls and provided real support by sending their children to school to a certain level of education. However, there are also parents who still limit their children's education to only a certain level, mainly due to limited economic reasons and the influence of cultural values ​​rooted in society. Factors such as economic dependence on girls and the view that higher education is not necessary for women are obstacles in realizing equal access to education. The implementation of Article 31 Paragraph (1) of the 1945 Constitution at the village level has not been optimal because there are no specific policies or programs from the village government that actually guarantee the right to education for girls. This study concludes that parental involvement plays an important role in addressing the inequality of access to education for girls in rural areas, and further support is needed from the government and the community to create an environment that is more supportive of girls' education. The implementation of more inclusive policies based on the needs of the local community is also very necessary to ensure that girls' right to education can be properly fulfilled.

Economic growth is a factor that influences the level of poverty, considering the increasing population which means that economic needs will also increase, so additional income is needed every year. The purpose of this thesis is to determine the effect of poverty and poverty on economic growth in Jambi Province in 2019-2023. The analysis method used is the Panel Data Regression Method. The results of the study obtained that poverty has a positive and significant effect on economic growth in Jambi Province in 2019-2023, so that the hypothesis (H1) proposed by the researcher is accepted with a significance value of 0.0308 <0.05 with a t-statistic value of 2.220545. Unemployment has a positive but not significant effect on economic growth in Jambi Province in 2019-2023 in Jambi Province, so that the hypothesis (H2) proposed by the researcher is rejected with a significance value of 0.4054> 0.05 with a t-statistic value of 0.838862. Poverty (X1) and Unemployment (X2) together influence economic growth in Jambi Province in 2019-2023 in Jambi Province (Y) with a calculated F value of 2.562611 and a significant value of 0.04680 <0.05 then Ho is rejected and Ha is accepted. For this reason, the government must increase employment opportunities and the government must pay more attention to the level of poverty as well as increase economic growth. Islam hates poverty and poverty because according to Islam, economic growth, wealth is a blessing and gift from Allah SWT that must be grateful for by mankind. Poverty, poverty and economic stagnation must be eliminated so as not to endanger faith, morals and morals, even divisions in society. Increasing quality employment opportunities and reducing poverty levels are important priorities to improve the quality of life of the community and create social stability.

This research aims to improve the learning outcomes of Natural and Social Sciences (IPAS) by applying a discovery learning model assisted by image media in grade V of SD Nurul Khoir, Jambi City. The method used is Class Action Research (PTK) which is carried out in two cycles. Each cycle consists of four stages, namely planning, implementation of actions, observation, and reflection. The research subjects amounted to 26 students. Data collection techniques are carried out through learning outcome tests, observation of teacher and student activities, and documentation. The results of the study showed a significant increase in the completeness of student learning outcomes. In cycle I, completeness reached 73.92%, and increased to 85.30% in cycle II. This improvement shows that the application of the discovery learning model combined with image media is effective in improving IPAS learning outcomes. This model encourages active involvement of students in the learning process, fosters curiosity, and hones critical and logical thinking skills. Image media as a visual aid has also been proven to be able to strengthen concept understanding and improve students' memory of the material studied. In addition, the learning process becomes more fun and meaningful because students are directly involved in the activity of discovering concepts through the stages of observing, questioning, gathering information, reasoning, and concluding. Teachers are no longer the center of information, but play the role of learning facilitators. This strategy is also relevant to the cognitive development characteristics of elementary school students who tend to favor concrete and visual learning. Thus, the application of the discovery learning model assisted by image media can be an alternative to an effective and innovative learning strategy in improving social studies learning outcomes. Teachers are advised to continue to develop adaptive, creative, and contextual learning methods and media.

This study aims to analyze the influence of Online Advertising on purchasing decisions for Skintific products by considering the mediating role of Trust and Social Media Engagement. Skintific, as a digital-native skincare brand, actively utilizes digital marketing strategies through various social media platforms such as Instagram, Tiktok, or e-commerce like Shopee to increase consumer appeal, especially in Malang City. This study uses a quantitative approach with the Partial Least Squares Structual Equation Modeling (PLS-SEM) method to test the relationship between variables. The sample was obtained through a purposive sampling technique with 114 respondents who are active consumers of Skintific. The results of this study indicate that Online Advertising has a significant effect on purchasing decisions, both directly and through the mediation of Trust and Social Media Engagement. Theoretically, this study extends the application of the Theory of Reasoned Action (TRA) in explaining the formation of attitudes and subjective norms of consumers towards digital advertising, as well as the Technology Acceptance Model (TAM) which shows how perceived ease and usefulness of digital advertising content affect user engagement. Customer Trust Theory in E-Commerce is used to explain how trust is formed in online transactions, while Relationship Marketing Theory emphasizes the importance of long-term interactions between brands and consumers. The Theory of Planned Behavior (TPB) expands this framework by adding the construct of behavioral control, which explains how consumers' perceptions of ease and barriers contribute to purchasing decisions. Social Influence Theory is used to understand the influence of social norms and online community opinions on purchase intentions, and Uses and Gratifications Theory (UGT) to examine consumer motivations in accessing and interacting with digital content based on information needs, affection, and self-identity. This research provides theoretical contributions in strengthening the relevance of integrating several consumer behavior theories in a digital context.
