The Zakat Aware Community Movement is an initiative to raise Muslims' awareness of the importance of zakat as a religious obligation and socio-economic instrument. The goal is to encourage people to pay zakat, both zakat mal and fitrah, correctly and on target to help the poor and reduce poverty and social inequality. Zakat not only has spiritual value, but also a strategic role in welfare distribution. Awareness of zakat is expected to counter consumptive behavior or hedonism, which in Islam is known as israf (excessive) and tabdzir (wasteful). The concept of “mâl” (wealth) in Islam is everything that can be legally owned and utilized, such as houses, money, gold, and others. Blessed wealth is wealth that is obtained lawfully, benefits others, and is used to get closer to Allah. Islam also pays great attention to poverty, which is described through the terms fakir and miskin. For this reason, zakat as the third pillar of Islam has a major role in overcoming it. For those who are reluctant to pay zakat, Islam recognizes the punishment of ta'zir - a punishment imposed by the ruler to safeguard the public interest. Finally, zakat that is paid consciously and sincerely can bring blessings to wealth, strengthen social solidarity, and strengthen the economic resilience of the people.

Oil and gas companies generally have large green areas as part of fulfilling environmental and aesthetic obligations in industrial areas. Routine maintenance such as grass cutting produces organic waste that needs to be managed efficiently to prevent negative environmental impacts. This study aims to calculate the generation of grass waste in oil and gas company areas by comparing two methods: direct weighing and sampling methods. The direct weighing method is carried out by collecting and weighing the results of the cutting in a limited area, while the sampling method involves taking samples from several representative points and extrapolating the results to the entire area. The results showed that the average grass waste generation was 0.286 kg/m². With an area of ​​around 1,000 m², the total generation is estimated to reach 286 kg. Both methods have proven to complement each other: direct weighing provides precise data, while the sampling method allows for efficient estimation for larger areas. This data can be used as a basis for planning more adaptive, effective, and sustainable grass waste management, including the use of waste as organic compost that has economic value and is environmentally friendly.

Oil and gas industry activities have the potential to produce high carbon emissions, so Green Open Space (RTH) is needed as an effort to mitigate environmental impacts. Shrub vegetation that grows in RTH areas requires routine maintenance, but this process produces vegetation waste that has not been studied quantitatively. This study aims to analyze the generation of shrub vegetation waste using a sampling method as a basis for sustainable waste management planning. The method used is sampling on a 1 m³ cube-shaped plot in three locations with different vegetation characteristics. Cutting is done manually using simple tools, then the waste produced is put into a measuring box to calculate its volume. The results show that sample point 1 produces 1.00 m³, sample point 2 is 0.50 m³, and sample point 3 is 0.30 m³. The average volume of shrub waste generation is 0.60 m³ per square meter. This data is important for planning the capacity of equipment, labor, and temporary waste disposal locations. In addition, the characteristics of waste that is easy to dry and has a high organic content opens up the potential for reuse as compost or biomass. This method has proven to be effective and efficient in supporting environmentally friendly vegetation waste management strategies as well as part of compliance with environmental regulations such as PROPER.
