This study examines the phenomenon of Muslim consumer consumptive behavior in the digital era, focusing on online shopping activities through e-commerce platforms. The main goal is to examine the conformity of consumption behavior with the principles of consumption ethics in Islam. Using a qualitative descriptive approach, data was collected through in-depth interviews with selected Muslim consumers as well as observations of purchasing patterns over three months. The results show that the ease of access to technology, the intensity of promotion, and the influence of social media are the dominant factors that encourage impulse buying behavior. This phenomenon creates a gap between actual consumption practices and Islamic ethical values, especially related to the principles of moderation (wasathiyah), avoidance of waste (israf), and social responsibility in shopping. While some respondents showed awareness of these values, the pressures of the digital environment and consumptive lifestyles often obscure ethical considerations in purchasing decision-making. The implications of these findings emphasize the urgency of strengthening Islamic consumption literacy through digital education, awareness campaigns, and the integration of religious values in ethical marketing strategies. This research is expected to be the basis for the development of sustainable consumption policies based on spiritual values, as well as encourage Muslim consumers to be more critical and wise in facing the evolving dynamics of digital commerce.

This study aims to analyze in depth the influence of business legality on the growth and increased competitiveness of Micro, Small, and Medium Enterprises (MSMEs). Business legality is seen as a crucial foundation in strengthening the position of MSMEs in the market, as it not only provides legal certainty but also fosters consumer trust in the quality of the products offered. This study uses a qualitative approach with data collection techniques such as field observations, in-depth interviews with business actors, and relevant documentation studies. The results show an increase in public awareness of the importance of having business legality, as evidenced by the increasing number of MSMEs officially registering their business permits. Furthermore, legality has been proven to increase the credibility of MSMEs, expand market access, facilitate collaboration with the private sector and government agencies, and open up opportunities for obtaining capital support. A significant increase in consumer trust is also evident, as MSME products with legality are more easily accepted and marketed through various distribution channels. Thus, this study confirms that business legality is not merely an administrative requirement, but rather a strategy that can encourage sustainable business growth and increase competitiveness at the local and national levels. In conclusion, the synergy between MSMEs and the government is the main key in encouraging the creation of a healthy, transparent, and highly competitive business ecosystem.

Young generations in the digital era face serious challenges in maintaining their Islamic identity due to the rapid flow of globalization, the penetration of popular culture, and the influence of social media, which often contradict Islamic values. This condition has led some adolescents and youth to experience moral degradation, a decline in interest toward religious studies, and a tendency to be more attracted to instant entertainment content. Conventional religious studies that are monotonous are often less appealing to Millennials and Gen Z, thus requiring innovative models of religious education that are relevant, engaging, and suitable for the characteristics of the digital generation. This Community Service Program (KKN) carried the theme “Strengthening Islamic Character of Young Generations through Interactive Multimedia-Based Studies at the Youth, Sports, and Tourism Office of Central Lampung Regency.” The main objective was to improve the understanding, internalization, and practice of Islamic values through creative, participatory, and enjoyable approaches. The program was implemented over one month with eight face-to-face sessions. The methods included interactive lectures, motivational video screenings, Islamic animation, group discussions, digital quizzes, and the establishment of an online discussion group via WhatsApp to maintain continuity of learning. Evaluation was carried out through field observation, pre-test and post-test, as well as in-depth interviews with participants and partners. The results showed an increase in religious understanding from an average of 58% to 82%, with active participation reaching 87%. Moreover, a youth community named Forum Pemuda Islami Lampung Tengah (FOPILTENG) was established, which is committed to continuing monthly studies independently. Technical obstacles such as limited multimedia facilities were successfully overcome by facilitators’ creativity, including utilizing simple devices and free digital platforms. Overall, the interactive multimedia-based approach proved to be effective in enhancing learning motivation, strengthening Islamic character, and fostering togetherness among youth. This model has the potential to be replicated in other regions as a strategic effort to nurture a religious, well-characterized, and competitive young generation in facing global challenges.

This research is a library study aimed at analyzing the various reasons for curriculum changes in Indonesia. Curriculum evaluation plays a crucial role in ensuring the quality and relevance of education by adapting to the dynamic changes in society. It helps identify the strengths and weaknesses of the curriculum and provides recommendations for improvement. However, several problems arise during implementation, particularly when teachers feel the time allocated to adapt to the new curriculum is insufficient, coupled with gaps in school facilities that make the implementation appear forced. The evaluation focuses on several key aspects: content, learning strategies, media, student learning outcomes, and teacher readiness, as teachers are the main drivers of knowledge transfer in the classroom. The qualitative descriptive approach, in the form of library research, collects data through systematic reviews, analysis stages, and information extraction from various sources. Over the course of the education system in Indonesia, from 1947 to 2024, the curriculum has undergone numerous changes. While these changes aim to improve the learning process and achieve optimal educational quality, they have had both positive and negative impacts. The influence of political agendas and the priorities of the ruling government have significantly shaped these curriculum changes. Despite these challenges, the rationale behind the changes lies in the effort to improve the learning experience and keep educational content up to date, reflecting the needs of the times. In conclusion, curriculum changes are essential to maintaining educational relevance, but proper preparation, sufficient time for adaptation, and adequate facilities are critical to the successful implementation of these changes. The research highlights the ongoing struggle to balance educational reforms with practical considerations for educators and students alike.

Immune Thrombocytopenic Purpura (ITP) is a bleeding disorder characterized by a low platelet count (<100,000/µL) caused by decreased platelet production or opsonization by antibodies, leading to platelet destruction by the reticuloendothelial system. ITP is one of the most common etiologies of bleeding disorders, especially in children. The prevalence of ITP in children is estimated to be around 1.9 to 6.4 cases per 100,000 children annually, while in adults, the prevalence is lower, at about 3.3 cases per 100,000 people per year. In the United States, the incidence of ITP is reported to be around 1.6 per 10,000 people annually. Clinical manifestations of ITP include petechiae, purpura, and/or ecchymosis, which are usually found on the upper and lower extremities. Mucocutaneous bleeding symptoms such as epistaxis and gum bleeding are also common in patients. These symptoms can vary depending on the severity of thrombocytopenia and individual responses to the condition. Diagnosis of ITP is made through a thorough medical history, physical examination, and rapid supportive tests to confirm the diagnosis and differentiate ITP from other conditions with similar symptoms. Proper and timely management is crucial to prevent further complications, including more severe bleeding or organ damage. With effective management, the quality of life of patients can be improved, and the risks associated with ITP can be minimized. Therefore, early detection and optimal management are key in addressing ITP, particularly in children who are more vulnerable to this bleeding disorder.

Surgical procedures, including laparoscopic surgery, may cause preoperative anxiety arising from fear of the surgery process, uncertain outcomes, and postoperative pain. This anxiety can affect anesthesia and recovery aspects. The purpose of this study was to determine the effect of Murottal recitation of Surah Ar-Rahman on anxiety in preoperative laparoscopy patients. This study employed a quasi-experimental design with a pretest–posttest control group. A total of 40 respondents were recruited using total sampling. Data were collected through questionnaires. Data analysis was conducted using the Wilcoxon test for within-group differences and the Mann-Whitney test for between-group differences. The majority of respondents in both intervention and control groups were late elderly, employed, male, and had no history of illness. Before therapy, anxiety levels in both groups were predominantly moderate. After therapy, most respondents in the intervention group experienced mild anxiety, whereas in the control group most remained in the moderate category. Statistical analysis showed a significant effect of Murottal recitation of Surah Ar-Rahman on reducing anxiety, both in the intervention group (Z = -5,477; p = 0.000) and the control group (Z = -2.000; p = 0.046). Overall, Murottal recitation of Surah Ar-Rahman was proven to be significantly effective in reducing respondents’ anxiety levels (Z = -4,534; p = 0.000). It is recommended that families play an active role in supporting anxiety reduction in patients undergoing surgery, for example, by suggesting or facilitating the patients to listen to Murottal recitation of Surah Ar-Rahman.

This study aims to explore the potential of cassava extract (Manihot esculenta)-based growth media for isolating microorganisms from soil. The use of alternative culture media is crucial, especially in regions with limited access to commercial media such as Nutrient Agar or Potato Dextrose Agar, which are relatively expensive. Cassava, a tropical tuber rich in starch and widely available in Indonesia, offers significant promise as a natural substrate for microbial growth. Microbial isolation was performed using a serial dilution method on soil samples collected from an organic garden. The media was prepared from cassava juice mixed with agar and glucose, sterilized, and poured into petri dishes. After inoculation, microbes were incubated for seven days at room temperature. Colony morphology was observed macroscopically, and Gram staining was used to identify bacterial characteristics. The results revealed that cassava extract media effectively supported the growth of diverse microbial colonies, varying in shape, color, and edge structure. Most isolates were identified as Gram-positive, with rod and coccus forms. The presence of pigmented colonies indicates the potential of certain isolates to produce bioactive compounds. In conclusion, cassava extract-based media is a viable alternative for soil microbiology studies. It is not only cost-effective but also facilitates the exploration of local microbial diversity with potential applications in biotechnology, including bioremediation and enzyme production. This approach encourages the use of indigenous resources in scientific research, promoting sustainability and accessibility in microbiological practices.
