This study employed a quantitative method, distributing Respondents were selected from ten zakat management institutions. The data analysis technique used was a composite index comprising five dimensions and sixteen indicators, covering the following dimensions: Governance and Institutions. Fundraising. Distribution and Impact. Finance and Efficiency, and Social and Environmental Dimensions. The results of the study indicate that, zakat institutions have a sustainable status in managing zakat and alms. However, several key dimensions need to be focused on to encourage sustainability in zakat fund management, particularly about financing issues. In addition, social and environmental issues also need to be a concern for each institution in its support of sustainable development. Further discussion is required to strengthen regulations and governance within zakat institutions. This is to enhance the role of zakat institutions in improving community welfare. In addition, zakat institutions need to develop potential in the fields of digitalisation and technological This is to facilitate the fundraising system for institutional sustainability. support the achievement of the SDGs, zakat institutions also need to develop distribution models that are impactful and sustainable. Keywords: Alms. Index. Infak. Institution. Zakat INTRODUCTION Indonesia is committed to implementing the Sustainable Development Goals (SDG. In the management of zakat, infaq, and sedekah, this context is evident from several points in the SDGs, namely the eradication of poverty, the ending of hunger, decent work and economic growth, and good health and well-being (Thacker et al. , 2. Zakat, infaq, and sedekah have a positive impact on IndonesiaAos economic growth (Badriyah & Munandar, 2. Additionally. ZIS has a positive impact on community welfare (Sakti & Fahrullah, 2. For example. LAZISNUAos management of ZIS funds can have a positive impact on changes in community welfare (Munawaroh, 2. Zakat, infaq, and sedekah funds in Indonesia have great potential if collected. The potential is IDR 327 trillion per year. In 2023. ZIS fund collection increased by 43. from IDR 22. 48 trillion to IDR 32. 32 trillion. Meanwhile, the condition of the second semester of 2024 was recorded at IDR 26. 13 trillion. By the end of the first quarter of 2025, the collected ZIS funds amounted to IDR 41 trillion (Amin, 2. A 2023 The Author.

This can be seen from the level of trust among muzaki . akat giver. , which is highly dependent on the transparency of financial reports, governance, and program reporting (Ascarya & Yumanita, 2. addition, the long-term success of this initiative also requires monitoring and evaluation to assess its real impact on the mustahik (Muwardi et al. , 2. Collaboration between zakat institutions and the government, distributing corporate CSR, and embracing NGOs can also increase the scope and success in distributing these funds (Hudaefi et al. , 2. However, many zakat fund management institutions experience obstacles in their operational processes. Many zakat institutions still rely on volunteers or human resources with limited managerial skills, especially in the regions (Kurnia & Makhtum, 2. This highlights the importance of more structured and Sharia-based zakat management by enhancing human resource competencies, promoting Islamic culture, and utilizing appropriate technology (Embun et al. , 2. Therefore, it is essential to implement a robust training program to equip employees with the necessary skills (Badrudin & Deviyantoro, 2. In addition, the distribution of these funds that are not on target is considered a failure of the ZIS institution. The distribution of zakat is sometimes still consumptive rather than productive, and the distribution is not based on the latest poverty data. The effect is an increase in poverty rates and hinders fundamental community inclusion (Rasyid & Hannase, 2. Previous research has been conducted by Yunita & Al-Ayubi . the collection and distribution of ZISWAF funds have fulfilled the principles of maqasid sharia . ustice, benefit, sustainabilit. Social and educational programs are implemented accountably and contribute to community empowerment. Other research focuses on funding for school construction and scholarships for underprivileged students, as well as the distribution of emergency assistance and local agricultural training programs. In addition, free health services and education on the importance of nutrition (Mansyur & Malik, 2. Based on the above, the researcher aims to determine the level of operation of zakat institutions in managing zakat funds. This can encourage evaluation and monitoring of zakat institutions in increasing professionalism in managing institutions and gaining trust from the muzaki LITERATURE REVIEW Definition and Legal Basis of ZIS The word zakat itself is derived from the words "al-barakat," meaning blessing. "alnamaw," meaning growth and development. "ath-thahir," signifying purity. and "ashshalhu," meaning goodness or peace. Law No. 23 of 2011 states that zakat is a form of wealth that must be distributed by a Muslim or a business entity to those entitled to receive it, according to Islamic law. According to PSAK 109 (IAI, 2. , infaq refers to the expenditure of wealth by the owner to achieve physical and spiritual well-being for oneself or others. Infaq can be defined as spending or using wealth for good purposes.

The management of zakat, infaq, and alms requires zakat administrators to submit periodic financial reports to the community, zakat payers, and the relevant government This is stipulated in Article 24 of Law No. 23 of 2011. Furthermore. Article 3 states that the purpose of zakat management is to improve the effectiveness and efficiency of zakat management services and to enhance the benefits of zakat. This law directly encourages Zakat Amil Institutions (LAZ) to have transparent financial recording and reporting systems, which aligns with the objectives of PSAK 109. The Minister of Religious Affairs Regulation is a more technical derivative of the aforementioned law and government regulation. The PMA regulates the technical governance of zakat institutions in more detail, covering aspects such as establishment, management, collection, distribution, utilisation, and reporting. PMA No. 31/2019 partially replaces PMA No. 52/2014 to update procedures for emphasising the use of information technology and digital reporting systems, and regulates standard formats for reporting zakat, infaq, and alms funds. In addition. LAZs are required to submit periodic financial reports to BAZNAS. PMA No. 5/2019 focuses on the procedures for distributing and utilising zakat funds, requiring the recording and documentation of evidence of LAZs are also encouraged to record distribution realisation in a structured manner, according to standards. Meanwhile. PMA No. 5/2016 provides more detailed regulations for the processes and technical operational standards of LAZs. This MUI fatwa clarifies the Sharia principles that LAZ must uphold. It also provides practical guidelines for the collection, management, distribution, and reporting of zakat. This MUI fatwa is not administrative in nature, such as a law, presidential decree, or government regulation. Instead, it is normative and principled, directing LAZ to manage zakat by Islamic law. Furthermore, the MUI fatwa provides guidelines on permissible and impermissible activities, who is entitled to receive zakat benefits, distribution proportions, and other related matters. The MUI fatwa also requires a clear separation between zakat, infaq, and sadaqah funds. Meanwhile. PSAK 109 serves as a technical tool to ensure LAZ implements the fatwa in a measurable and auditable manner. This law improves previous provisions and regulates zakat, infaq, and alms paid through the National Zakat Agency (BAZNAS). Zakat Amil Institutions (LAZ) established/recognized by the government, may be deducted from the taxpayer's gross income, so that zakat payers receive fiscal benefits . ower taxe. , encouraging compliance by zakat payers in distributing zakat through official LAZ. Law No. 7 of 2021 requires LAZ to be managed professionally, accountably, and officially registered, so that zakat payers can claim tax deductions. Meanwhile. PSAK 109 is a technical standard that facilitates the fulfilment of fiscal and Sharia reporting requirements METHOD This study utilizes primary data, which was collected by distributing questionnaires to respondents.

RESULTS AND DISCUSSION The Zakat Collection Institution plays a significant role in increasing the collection of zakat, infak, and sedekah (ZIS). As an official institution recognized by the government and society, this institution functions not only as a fund collector but also as a professional and trusted planner of collection strategies. Thanks to the existence of the institution, the zakat collection process becomes more structured, transparent, and accountable, thus fostering the trust of the muzaki. Innovation in zakat campaign programs, the utilization of digital technology, and personal approaches to prospective donors are also important factors that have contributed to the growth of ZIS funds every year. Thus, the existence of the Zakat Collection Institution is not only as a distributor, but also as the primary driver of community awareness and optimal participation in paying zakat. Governance and institutions Governance refers to the systems, structures, and processes that an institution uses to direct, manage, and oversee all its organizational activities. Its primary purpose is to ensure that the institution operates professionally, accountably, transparently, and in accordance with Sharia principles.

The results of the study show that the ten institutions that were respondents are categorized as sustainable in terms of governance and institutions. It needs to be emphasized again that a good governance and institutional system can increase the trust of muzaki in zakat management. This is in line with research by Jamali et al. , . which shows that systematic ZIS distribution governance, including identification of mustahik, distributors, implementation, and monitoring and evaluation, has increased the welfare of mustahik LAZNAS YATIM MANDIRI LAZNAS MPAQ BIAS LAZ AZKA CENTER LAZISKU SUMUT LAZISMU BINJAI LAZ SOLOPEDULI LAZISMU ASAHAN LAZISKU KB PII BAZNAS LAZ Rabbani 0,75 0,75 0,65 Figure 1 LAZ Governance and Institutional Index Diagram Figure 1 shows that the National Zakat Agency has a high value compared to other zakat institutions. This is because BAZNAS, as a central institution, has been able to implement good governance and effective institutions. Other zakat institutions should observe how BAZNAS manages institutional governance to gain the trust of muzaki, which they have achieved so far. Fundraising Fundraising is a strategic activity carried out by the Zakat Amil Institution (ZAKAT) to collect ZIS funds from muzakki . akat giver. and other donors, including individuals and corporations, to be distributed to the mustahik by Sharia provisions. The goal is to increase the potential for collecting zakat, infak, and sedekah. In addition, it makes it easier for Muzaki to fulfill their obligations and social charity. The results of the study show that each zakat amil institution has made maximum efforts in collecting zakat.

Table 5 shows that there are zakat institutions that are quite sustainable and This is due to the small potential for collecting zakat, infaq, and alms. the other hand, the obstacle faced is that zakat institutions only rely on muzaki personally and have not expanded to utilize the potential of muzaki from institutions. This has an impact on institutional operations. This aligns with the research of Kasri & Putri . which suggests that a traditional fundraising strategy, combined with a partnership approach to collecting zakat and a community-oriented approach to communicating zakat, is necessary.

LAZ is required to manage the funds collected professionally, transparently, and by Sharia accounting standards, such as PSAK 109. This financial management not only focuses on the amount of funds received and distributed, but also on how the operational costs of the institution can be minimized so that the mustahik can enjoy a larger portion of zakat funds. Efficiency is reflected in the ratio of operational costs to the total collection A LAZ with sound financial management can maintain this ratio at a low level, without compromising the quality of service or the effectiveness of the distribution Efforts to achieve Efficiency are carried out, for example, by digitizing administrative processes, utilizing an integrated financial system, and optimizing human resources and volunteer management. In addition, the financial aspect of LAZ also concerns how the institution maintains its liquidity and solvency, ensuring it is always ready to distribute funds according to its designation while meeting operational needs. Accurate, timely, and regularly audited financial reports are crucial instruments for maintaining the trust of muzakki and the public, as well as a form of accountability. Finances that are managed efficiently and transparently not only improve LAZAos reputation but also strengthen the institutionAos long-term sustainability. Through a healthy financial system. LAZ can more freely innovate programs, respond to the dynamic needs of mustahik, and ensure a broader social impact. Thus, the financial and efficiency aspects are not just numbers, but are the primary foundation for creating successful management of ZIS funds that are efficient and sustainable.

The differences in these values show variations in the effectiveness and efficiency of ZIS fund management between institutions, which can be influenced by governance, accountability systems, and digital innovations implemented This finding aligns with research by Sari and Susilowati . , which emphasizes that zakat institutions implementing transparent management systems and digital technology tend to have better financial performance and a significant impact on muzakki trust, resulting in more equitable zakat distribution. Social and environmental Social and environmental dimensions are increasingly becoming a focus in the management of zakat, infaq, and sedekah by the Zakat Amil Institution (LAZ). Not only limited to the distribution of consumptive funds. LAZ programs are now widely directed to provide fundamental contributions to social development and environmental In the social aspect. LAZ plays a role in empowering the mustahik through education, health, skills training, and economic empowerment programs based on micro and small businesses. This approach not only helps the mustahik meet their basic needs, but also encourages independence, enabling them to transform into muzaki in the future. The management of social and environmental programs encourages the creation of cross-sector collaboration. LAZ can work with the government, business world, local communities, and international institutions to expand the reach of program impact and This kind of collaboration further strengthens LAZAos position as an institution that not only manages funds but is also an active and visionary agent of social change.

Sustainability of Zakat Amil Institution Index A sustainable Zakat institution is an organization that not only focuses on collecting and distributing Zakat. Infaq, and Sadaqah (ZIS) funds, but also manages these funds with a long-term approach that is planned, professional, and accountable. Sustainability is reflected in the institutionAos ability to ensure that the programs it runs can continue to provide benefits to the most vulnerable without relying entirely on fluctuations in incoming funds. Institutions like this build good governance, transparency, and compliance with Sharia standards and regulations, including the implementation of PSAK 109, to strengthen the trust of muzaki and the public. In addition, sustainable zakat institutions can innovate in mustahik empowerment programs, so that the distribution of funds is not only consumptive but also productive and has a long-term impact. Programs such as strengthening UMKM, skills training, education scholarships, and community-based health programs are real examples of the role of zakat as an instrument of social development. This approach helps mustahik become more independent, potentially even becoming muzaki in the future, thereby creating a cycle of goodness that remains sustainable. A 2023 The Author.

The results of the index measurement show that zakat institutions that have good governance and compliance with regulations can significantly increase ZIS fund collection.

This step is crucial for increasing the trust of muzaki . and maintaining the institutionAos reputation. It is recommended that institutions develop digital innovations, such as online donation platforms, digital wallets, and mobile-based applications, to expand the reach of their fundraising efforts.

Zakat institutions are advised to continue improving the competence of their human resources through regular training and professional zakat The use of information technology is also important, both for reporting systems, monitoring, and evaluation of the impact of the program REFERENCE
