This study investigates the development of Indonesian language literacy among third-grade elementary school students. The primary problems identified were acute classroom passivity and low reading comprehension, evidenced by an initial learning mastery of only 45.16%, which were largely driven by conventional teacher-centered pedagogy. The objective of this research is to enhance early-grade reading literacy and active participation through an innovative instructional intervention. The proposed method employed a two-cycle Classroom Action Research (CAR) design at SDN Jrebeng Kulon 1, integrating the Problem-Based Learning (PBL) model assisted by serial picture media. This approach utilizes chronological visual scaffolding to facilitate narrative comprehension for students in the concrete operational stage. The results demonstrated a highly significant academic progression: classical learning mastery increased to 70.97% (mean score: 80.80) in Cycle I and culminated in an absolute 100% mastery rate (mean score: 94.51) by the end of Cycle II. The synthesis of these findings reveals that transitioning from static visual aids to serial visual stimuli within a problem-oriented framework effectively mitigates cognitive dissonance and eradicates classroom passivity. In conclusion, the integration of the PBL model with serial picture media serves as a comprehensive pedagogical solution that not only maximizes cognitive reading comprehension but also reconstructs students' verbal articulation and social-collaborative skills, offering a highly scalable strategy for early primary education.

The study aims to analyze the role of digital media as a distracting factor affecting the faith loyalty of Catholic adolescents in their relationship with God amid religious pluralism in Indonesia. The development of digital media has transformed how adolescents understand, express, and live out their faith, while simultaneously presenting both opportunities and ambivalent challenges. This research employs a qualitative approach using a library research method, analyzing various theological, sociological sources, and Church documents. The findings indicate that digital media can serve as a broad and participatory space for expressing faith, but it also has the potential to create distractions in three main dimensions: cognitive, affective, and practical. Cognitively, adolescents experience confusion in understanding faith teachings due to the diversity of information available. Affectively, there is a shift in orientation from a relationship with God toward the pursuit of emotional gratification in digital spaces. Practically, there is a decline in engagement in concrete religious practices. Within the context of religious pluralism, this complexity intensifies and influences the formation of adolescents’ faith identity. This study also finds that digital media does not only have negative impacts but also holds positive potential as a means of deepening faith when used critically and reflectively. Therefore, the role of the Church is essential through contextual, dialogical, and integrative pastoral accompaniment combined with critical digital literacy. Through this approach, adolescents are expected to integrate their digital experiences into a more mature, authentic faith life rooted in a deeper relationship with God.

Complementary feeding plays a vital role in meeting the nutritional needs of infants and toddlers. However, food safety remains a concern, particularly for homemade commercial complementary foods. This study aimed to assess the microbiological quality and hygiene sanitation practices of homemade commercial complementary foods vendors in the service area of Karangandong Public Health Center, Gresik.

This study aims to analyze student time management and its relationship to academic productivity among students in the Economics Education Study Program, Jambi University, class of 2023. This study used a qualitative approach with data collection techniques through in-depth interviews with a number of students selected purposively. The results showed that most students were unable to manage their time optimally, as reflected in the habit of procrastinating on assignments, a lack of structured planning, and an imbalance between academic and non-academic activities. Many students tended to work on assignments only close to the deadline and found it difficult to maintain a consistent schedule. Conversely, students who had a more structured time plan, such as compiling daily to-do lists and setting priorities, demonstrated better academic productivity. They were able to complete assignments on time, produce better quality work, and were more active in the learning process and class discussions. This study confirms that effective time management plays a crucial role in improving student academic productivity, both in terms of the quality of work results and the timeliness of assignment completion. Therefore, more intensive efforts are needed to increase students' awareness and skills in time management, so they can achieve optimal learning outcomes, reduce stress levels, and face academic demands more efficiently. In this context, developing good time management strategies is essential to help students maximize their academic potential.

The emergence of Large-Format Printing (LFP) technology has transformed global visual communication by enabling the production of large-scale, high-quality printed materials, significantly influencing Nigeria’s graphic design industry. This study aims to examine the impact of LFP on graphic design practice (GDP) in 21st-century Nigeria and propose strategies for sustainable development while addressing emerging challenges. A mixed-method approach was employed, with a primary qualitative focus through interviews and participant observation, supported by quantitative data collected using a Likert-scale questionnaire to assess designers’ perceptions of LFP’s influence. The findings reveal a dual impact. On the positive side, LFP has enhanced design scale, print quality, creative flexibility, and production efficiency, effectively overcoming the limitations of earlier methods such as letterpress printing, manual clamp offset printing, and hand-painted signboards. However, several challenges persist, including the oversaturation of practitioners, increased design piracy, and issues of color inconsistency, which undermine quality outcomes. These challenges highlight gaps in professional standards and regulation within the industry. The study concludes that while LFP has driven innovation and growth in Nigeria’s graphic design sector, its optimal benefits are constrained by the proliferation of unaccredited freelance designers. Therefore, the study recommends the implementation of targeted training programs and stricter professional accreditation systems through relevant regulatory bodies to ensure sustainable development and maximize the transformative potential of LFP technology.

Waqf is one of the instruments of Islamic economics that holds great potential for improving community welfare and promoting sustainable socioeconomic development. However, this potential has not been fully realized due to low public participation in waqf. This situation indicates that messages and education regarding waqf have not been effectively communicated to the general public. This study aims to analyze how the distribution, promotion, and advertising of waqf messages are conducted to the public through a case study of the Indonesian Waqf Board in South Tangerang City. The method used is a descriptive qualitative approach with a constructivist paradigm. Data collection was conducted through interviews, observations, documentation, and literature review to obtain a comprehensive picture of the waqf communication strategies implemented. The results of the study indicate that the distribution of waqf messages is still limited to seminars, workshops, and incidental activities, resulting in uneven information reach. Waqf promotion has also not been conducted consistently and remains conventional, while the use of digital advertising and social media has not been maximized. The main obstacles faced include low public literacy regarding waqf, a lack of professionalism among waqf administrators, and minimal public trust in waqf management. This study concludes that the development of waqf requires modern communication strategies through the digitization of messages, consistent promotion, increased institutional transparency, and intensive use of social media in order to significantly increase public participation in waqf.

In the digital era, e-commerce has developed not only as a platform for buying and selling activities but also as a strategic medium for marketing and business development. University students theoretically possess strong potential to become edupreneurs because they are closely connected to technology and supported by higher education environments. Nevertheless, the reality at Al-Amien Prenduan University indicates that students tend to act more as consumers in e-commerce rather than as entrepreneurs. This condition creates a gap between theoretical expectations and practical implementation, raising questions regarding the effectiveness of e-commerce in encouraging students’ entrepreneurial spirit. This study examines strategies for strengthening Edupreneurship graduates through the optimization of e-commerce. The research specifically explores ways to maximize e-commerce in supporting the development of Edupreneurship graduate profiles and improving graduates’ competitiveness in entrepreneurship and employment sectors. A qualitative approach with a case study method was employed at Al-Amien Prenduan University. Data were collected through observation, interviews, and documentation involving female students of the Islamic Education Edupreneurship program who actively engage in entrepreneurial activities through e-commerce platforms. The findings reveal that optimizing e-commerce can be achieved through identifying students’ digital competencies and needs, as well as utilizing flexible technologies that support broader market access and global transactions. In addition, strategies such as enhancing digital marketing creativity, strengthening market research capabilities, and understanding consumer behavior significantly contribute to entrepreneurial development. The study concludes that e-commerce effectively fosters entrepreneurial attitudes, adaptability, and competitiveness among students in facing the challenges of the digital economy.

This research is motivated by the phenomenon of high academic pressure among students who possess excessively high self-standards or perfectionistic personality traits. The primary issue examined is how these students manage their emotions amidst a constant fear of failure. This study aims to gain a profound understanding of the emotion regulation strategies employed by perfectionistic students. The research method used is qualitative with a phenomenological approach to explore the participants 3 subjective experiences. Data were collected through in-depth interviews with active students selected via purposive sampling. The results indicate that participants tend to use maladaptive strategies, such as expressive suppression and procrastination, when they feel unable to achieve maximum targets. Social support and emotional maturity were identified as key factors helping them transition toward adaptive strategies. The study concludes with an emphasis on the necessity of specialized psychological support for perfectionistic students to develop self-compassion.

Corruption remains a persistent challenge in Indonesia because it weakens public trust, undermines welfare, and obstructs equitable development. This article examines how Aristotle’s virtue ethics can contribute to anti-corruption efforts by addressing the moral roots of corrupt behavior. The study argues that corruption is not only a legal or administrative violation but also a failure of character, judgment, and commitment to the common good. Using a qualitative conceptual design, the article employs philosophical analysis, a structured literature review, and Socratic questioning to examine the relationship between virtue, leadership, and public integrity. The analysis identifies three principal roots of corruption: weak moral character, poor ethical judgment, and self-interest over the common good. It shows that Aristotelian ethics offers an integrated response through the cultivation of moral virtue, intellectual virtue, and practical wisdom. The findings suggest that virtue-based ethics is most effective when combined with anti-corruption education, ethical leadership, stronger rule-of-law implementation, and institutional arrangements that reduce opportunities for abuse of power. Aristotle’s framework does not provide a complete solution, but it offers a valuable normative foundation for strengthening ethical public culture in Indonesia.

Vegetables are food commodities widely consumed by the public due to their high nutritional content. Chili (Capsicum annuum L.), green beans (Phaseolus vulgaris L.), and Chinese cabbage (Brassica pekinensia L.) are among the vegetables that can be processed into various delicious dishes or consumed fresh as raw vegetables. To obtain healthy and high-quality vegetable crops, pesticides are commonly used to control pests that may damage the plants. One of the widely used pesticides is chlorpyrifos, which can leave residues that may pose both acute and chronic health risks. Therefore, it is necessary to analyze the levels of chlorpyrifos pesticide residues in vegetables. The residue levels were determined using a UV-Vis spectrophotometer at a wavelength of 230 nm with dichloromethane as the solvent, while qualitative analysis was performed using HPLC by comparing the retention times of standard solutions and vegetable samples. In this study, washing treatments were applied to the vegetables using dichloromethane, distilled water, well water, and tap water (PDAM) to evaluate the effect of washing on pesticide residue levels. The concentrations of pesticide residues in unwashed vegetables were chili (2.6680 ± 0.0214 mg/kg), green beans (2.4658 ± 0.0193 mg/kg), and Chinese cabbage (2.7950 ± 0.0379 mg/kg). The washing process was carried out three times for each solvent. After three washings using dichloromethane and distilled water, pesticide residues were no longer detected, whereas washing with tap water (PDAM) and well water still left residues, although at levels much lower than the Maximum Residue Limit (MRL). The health risk assessment showed that the aHQ and cHQ values were < 1, indicating that consumption within the recommended limits of these samples does not pose health risks, either in the short term or long term. This study provides important information that repeated washing is necessary to effectively reduce pesticide residue levels in vegetables before consumption.  

The increasingly complex global energy problem drives the need for efficient, low-cost, and environmentally friendly energy storage systems. This study aims to analyze the power performance of two symmetric supercapacitor prototypes using Nitrogen-doped Graphene-Like Carbon (N-GLC) as the electrode material and 1 M  as the electrolyte, with different electrode substrates: aluminum and copper. Both prototypes were tested through charging and discharging processes using resistive loads of 470 ohms and 560 ohms for 5 minutes. The analyzed parameters include voltage, current, power, and output energy. The results show that the aluminum electrode achieved a higher maximum charging power of up to 18 mW; however, its energy discharge efficiency was very low at only 0.87%. In contrast, the copper electrode demonstrated a more balanced charging and discharging performance with an energy discharge efficiency of 19.4%. Analysis also indicates that the copper substrate maintains better voltage stability after 6 hours of storage compared to aluminum, which experienced significant degradation. Thus, the copper electrode is superior in maintaining the power and stability of a simple N-GLC-based symmetric supercapacitor system.

Takaras River is a river basin that is vulnerable to pollution, particularly from the mercury usage in small-scale gold mining. This study aims to identify water quality based on mercury (Hg)and pH levels in the Takaras River. Samples were taken at two locations using a purposive sampling method. Results showed indications of mercury use on former gold mining land around the Takaras River altought the mercury content level was below 0.075 µg/L or 0.00075 mg/L in sample 1 and 2. Based on the test results, the acidity level (pH) in the two water samples from Takaras River is 3.86 and 3.84 in sample 1 and 2, compared to the maximum pH quality standard of 6-9 for Class II water, it is concluded that the scale of acidity in Takaras River is very low, indicating that the water quality in the Takaras River is highly acidic, abnormal, and shows signs of serious pollution. The implications of low pH levels in the Takaras River can cause damage to the Takaras River ecosystem, a decline in soil quality and fertility, and an increase in heavy metal toxicity in the environment surrounding the river.

The increasing demand for electrical energy and the limited availability of fossil fuels have driven the development of renewable energy sources, including marine current energy, which remains underutilized in coastal and remote maritime regions. This study presents the design and realization of a small-scale marine current power generation prototype using a horizontal axis propeller turbine with a NACA S814 blade profile and analyzes the effect of turbine rotational speed on electrical power output. The system converts marine current kinetic energy into mechanical energy through turbine rotation and subsequently into DC electrical energy using a generator, which is stabilized by a Buck–Boost Converter and Maximum Power Point Tracking (MPPT) for charging a 12 VDC battery. Real-time monitoring of electrical and mechanical parameters is implemented using an Internet of Things (IoT)–based system comprising an ESP32 microcontroller, a PZEM-017 sensor, and an RPM sensor. Experimental results demonstrate a positive correlation between water flow rate, turbine rotational speed, and generator output voltage. The system begins operating at a minimum flow rate of 35.2 L/s at 56 RPM, producing 0.2 V, while optimal performance is achieved at 45.3 L/s and 516 RPM, generating up to 13.3 V. These results indicate that the proposed prototype is a viable alternative renewable energy source for marine applications.

This study examines the effectiveness of Assemblr Augmented Reality (AR) in improving English vocabulary mastery among deaf students in an inclusive classroom setting. The research was conducted at SD N 2 Bengkala using a quantitative pre-experimental design with a one-group pre-test and post-test approach. The participants were Grade 5 deaf students selected through purposive sampling. Data were collected using a researcher-developed vocabulary test consisting of 15 items, which was validated through expert judgment and demonstrated high reliability (Cronbach’s Alpha = 0.815). Descriptive statistical analysis revealed a substantial improvement in students’ vocabulary scores, with the mean increasing from 45.00 in the pre-test to 76.50 in the post-test. The minimum score improved from 40 to 73, and the maximum score increased from 50 to 80. Inferential analysis using the Wilcoxon Signed-Rank Test showed a significance value of 0.180, indicating no statistical significance due to the small sample size. However, the observed improvement indicates strong practical significance. The findings suggest that Assemblr AR enhances vocabulary learning by providing visual and interactive learning experiences that support deaf students’ cognitive processing. This study highlights the potential of AR technology as an effective instructional medium in inclusive education environments.
