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.

The policy plan to integrate parking fees into the Vehicle Registration Certificate (STNK), scheduled for nationwide implementation in 2027, has generated debate regarding contractual validity and fiscal justice. From the perspective of Islamic Economic Law, the transformation from a conventional pay-per-use retribution system to an annual prepaid system raises issues related to mutual consent (an-taradin) and the certainty of service benefits. This study aims to analyze the 2027 subscription parking policy using the framework of Maslahah Mursalah and the principle of distributive economic justice to assess its legitimacy as an instrument of public welfare. This research uses a normative legal method with conceptual and statutory approaches. Literature data are analyzed qualitatively through deductive reasoning to derive legal conclusions from general principles of Islamic economics in relation to contemporary fiscal policy. The findings indicate that the policy contains elements of Maslahah Mursalah, particularly in improving bureaucratic efficiency and preventing state revenue leakage (sadd adz-dzari'ah). However, from the perspective of distributive justice, the policy may contain elements of dzulm (injustice) if it is not supported by fair tariff segmentation. Without guaranteed service availability for all payers, mandatory annual parking fees risk being categorized as akl al-amwal bi al-bathil (unlawful appropriation of wealth). Therefore, a zoning-based tariff system is recommended to ensure fairness between obligations and benefits.

This study examines the effectiveness of zakat distribution during the leadership of Umar bin Abdul Aziz and its relevance to poverty alleviation models in Indonesia. Structural poverty remains a persistent challenge in Indonesia’s economic development, requiring systematic and sustainable solutions. Within Islamic economic thought, zakat functions not only as a religious obligation but also as a fiscal instrument capable of promoting social welfare and economic independence. This research employs a qualitative approach through historical and literature study methods, analyzing classical Islamic governance practices alongside contemporary zakat management in Indonesia. The findings reveal that the success of zakat distribution under Umar bin Abdul Aziz was supported by centralized governance, strong institutional reform of Baitul Mal, strict supervision, and integrity-based leadership, resulting in effective wealth redistribution and significant poverty reduction. The study further finds that productive zakat distribution, institutional integration, regulatory reinforcement, and digital transparency are crucial elements for enhancing the performance of zakat institutions in Indonesia. The implications suggest that strengthening governance, accountability, and productive empowerment programs can transform zakat into a strategic socio-economic policy instrument capable of addressing structural poverty in a sustainable manner.

In demographic studies, population growth refers to changes in the number of inhabitants over a given period, measured by calculating numerical differences in population size and expressing them within specific time units to illustrate patterns of increase or decline. Based on data from Tembalang District in Figures 2025, the population growth rate in Kedungmundu Village rose by 0.51% between 2016 and 2025, with most residents relying on clean water services provided by PDAM Tirta Moedal as their primary source of drinking water. This study aims to estimate clean water demand based on projected population growth and to design a pipeline network system capable of meeting future needs. The analysis of water demand applies population projection methods, including arithmetic, geometric, and least square approaches, to compare their levels of accuracy, while the clean water distribution network is modeled using EPANET 2.0. One of the main challenges faced by PDAM is that service coverage has not yet been fully optimized. The ten-year projection results indicate that the arithmetic method provides a correlation value closest to 1, estimating a future population of 14,904 people with a total clean water requirement of 3.48 liters per second. To support this projected demand, the proposed network design utilizes High Density Polyethylene (HDPE) pipes with diameters of 12, 10, and 8 inches to ensure efficient and sustainable water distribution.

Equitable vaccine distribution is a global issue that has received increasing attention, especially since the increasing need for vaccines in the face of modern pandemics. This study aims to analyze the inequality in vaccine distribution and the factors influencing vaccine hesitancy through a descriptive qualitative approach, utilizing literature studies and supporting data in the form of graphs. The analysis results show that high-income countries have significantly greater access to vaccines than middle- and low-income countries, creating inequalities that impact public health protection. Furthermore, levels of vaccine hesitancy were found to vary across social groups, with adolescents being the group with the highest rate of rejection due to the influence of misinformation and low trust in health institutions. These findings confirm that the success of a vaccination program is determined not only by the availability of equitable distribution but also by public acceptance, which is influenced by social, psychological, and ethical factors. Overall, this study emphasizes the importance of applying bioethical principles such as justice, beneficence, and autonomy in formulating effective and inclusive vaccination policies.

This literature review synthesizes a wide range of research findings that examine the role of auxin distribution direction in regulating leaf primordium patterning, known as phyllotaxis, in Arabidopsis thaliana. The reviewed studies consistently indicate that phyllotaxis represents a highly coordinated growth regulation mechanism that is primarily governed by Polar Auxin Transport (PAT), which is mediated by Pin-Formed (PIN) auxin efflux proteins. The polarity and spatial localization of PIN proteins generate dynamic auxin gradients within the shoot apical meristem, and these gradients function as key positional signals that determine the precise sites where new leaf primordia are initiated. Furthermore, auxin distribution is not regulated solely by PAT but is tightly integrated with genetic, cellular, and mechanical cues. Several studies highlight the role of transcription factors such as TMO5 in influencing PIN1 convergence and reinforcing auxin maxima at primordium initiation sites. In addition, the interaction between PIN polarity and the orientation of cortical microtubules suggests that mechanical stress and cytoskeletal organization contribute to the stability and directionality of auxin flow. Comparative analysis of the literature demonstrates that PAT and PIN proteins operate through interconnected mechanisms to control auxin distribution direction, which ultimately shapes the spatial arrangement and regularity of leaf primordium patterns. Overall, this review emphasizes the complexity and integration of hormonal, genetic, and mechanical signals in controlling phyllotaxis in plants.

Welfare for the poor is the most important topic in improving citizens. Islam as Ad-diin has offered several teachings for humans that apply universally with two dimensional characteristics, namely happiness and well-being in life in this world and in the hereafter. In the concept of the modern world, welfare is a condition where a person can fulfill basic needs, be it the need for food, clothing, shelter, clean drinking water as well as the opportunity to continue education and have adequate work that can support the quality of life so as to have a social status that leads to the same social status as other citizens. ZIS as an extension of the government in helping the needs of the poor with the aim of improving the welfare of the community who initially as zakat recipients turned into zakat givers, so that later the funds used will be evenly distributed and felt by the wider community. as well as purifying assets that may be accidentally mixed with assets that are forbidden for consumption. The urgency of ZIS in Sidowungu is one of the main elements of effective and efficient zakat management in order to realize the welfare of the community. As for the discussion of this article about the welfare pattern for the poor as the process of distributing ZIS funds in Sidowungu Village. The method used in this article is a quantitative approach. The subjects of this study were 165 poor people in Sidowungu Village, while the sample size was 65 poor people using probability sampling. The results of the study, processed using the PASW SPSS 23 for Windows program, showed that partial test results for H0 were rejected and H1 was accepted if the calculated t value was greater than the table t value or the sig value was less than 0.05. This means that the distribution of funds partially affected the welfare of the poor in Sidowungu Village. The magnitude of the influence between variables can be seen from the coefficient of determination of 0.079, meaning that 79.0% of the welfare of the poor in Sidowungu Village was influenced by the distribution of ZIS funds, while the remaining 21.0% was influenced by other variables not included in this study.

This study aims to analyze the influence of Corporate Image and Service Quality through Customer Satisfaction on Customer Loyalty at Semen Indonesia distributors in Gresik using the Structural Equation Modeling (SEM) approach. The study population consisted of 102 customers, all of whom were sampled. The results indicate that Corporate Image and Service Quality have a significant influence on Customer Satisfaction. Both variables were also shown to have a significant influence on Customer Loyalty. However, unlike several previous research findings, Customer Satisfaction did not have a significant influence on Customer Loyalty. This finding indicates that in the context of the cement distribution business, customer loyalty is not formed solely from satisfaction, but is more influenced by other factors such as consistent service quality, a strong corporate image, competitive pricing, and long-term business relationships. This study emphasizes the importance of strengthening image and improving service quality as key strategies for maintaining customer loyalty.
