Abstract

Steady developmental increase in urban and its buffer areas causes a decrease in rainwater catchment areas. Green roof system is emerging as a new form of technology that can improve the built environmental conditions. The purpose of this study was to simulate the application of green roof systems with cocopeat as planting media in reducing surface runoff water in urban buffer zones. Sub-watershed boundary analysis was carried out to determine the boundary of study area followed by land cover analysis using web-based software ?i-Tree Canopy? to obtain the area of roof cover within the study area. Rainfall analysis (2005-2014) was carried out to obtain the design flood discharge value at the study location. The simulation results show that the green roof system with 10 cm depth of cocopeat as planting medium is able to delay peak discharge in the study area to exceed the concentration time for all flood return periods. Green roof application simulation of 5% and 10% of the total roof cover area resulted in a reduction in peak discharge up to  3.12% and 6.24% respectively. This green roof system needs to be combined with rainwater harvesting systems to further reduce peak discharge in the study area.

Abstract

Kurang tertibnya administrasi Intansi Pemerintah desa dalam melaksanakan kewajiban pajaknya mulai dari pemotongan pajak, penyetoran sampai dengan pelaporan pajak, penelitian ini mengacu pada penerapan undang-undang perpajakan pada tahun terkait yang bertujuan untuk menganalisis penerapan perpajakan pada desa di kecamatan Kabila Bone. Penelitian ini menggunakan metode penelitian ini adalah Kuantitatif Deskriptif, yaitu penelitian yang digunakan untuk menganalisis data dengan cara mendeskripsikan data yang telah terkumpul sebagaimana adanya. data yang digunakan yaitu data sekunder berupa laporan pada buku kas pajak desa dan data primer yang berupa wawancara terhadap bendahara desa untuk memperkuat data yang diperoleh. Hasil penelitian menyatakan bahwa enam Desa di kecamatan Kabila Bone belum menerapkan penerapan pajak yang sesuai dengan UU dan Peraturan Menteri Keuangan. Kurangnya sosialiasi mengenai aturan terbaru dan kurangnya pengawasan yang dibuktikan dengan tidak adanya teguran dan sanksi atas kelalaian dalam pelaksanaan kewajiban pajak yang memicu terjadinya ketidaksesuaian antara Peraturan Menteri Keuangan dengan penerapan pajak yang dilakukan oleh bendahara desa terutama pada tahun 2021. Kata Kunci: dana desa; pajak desa; kuantitatif deskriptif; pajak penghasilan; pajak pertambahan nilai.

Abstract

This study aims to analyze the impact of Islamic investment on economic growth in Indonesia. Islamic investment, based on Islamic principles such as the prohibition of usury and speculation, has grown significantly in recent years. This research uses a qualitative approach with secondary data from financial reports, economic statistics, and related studies. The results show that Islamic investment contributes positively to Indonesia’s economy, particularly through the Islamic financial sector and increased financial inclusion. Islamic investment instruments, such as sukuk and Islamic mutual funds, provide stable and sustainable financing alternatives. Sukuk, for instance, is used to finance infrastructure projects that support economic growth. Additionally, Islamic financial products expand access to finance for communities previously excluded from the conventional financial system. However, challenges such as low financial literacy on Islamic finance, limited Islamic financial products, and the need for stronger regulations must be addressed. Therefore, strengthening policies and supporting infrastructure is necessary to optimize the development of Islamic investment in Indonesia.
