Tofu industry wastewater contains high organic material which reduces dissolved oxygen, contaminates water, and odor that potentially contaminates and pollutes receiving surface water. Constructed wetland is one of the recently proven efﬁcient technologies for wastewater treatment. This is due to vegetation diversity. Constructed wetland systems have been developed using water jasmine plants combined with filtration systems for the reduction of BOD, TSS, and oil and grease in tofu wastewater as a function of detention time. Detention times were varied at 5, 7, 9, 11, 13, and 15 days. The results revealed that the reduction of BOD, TSS, and oil and grease was influenced by detention time. The reduction efficiency of BOD, TSS, and oil and grease decreased with increasing the detention time. The combined system of constructed wetland and filtration using water jasmine plants effectively reduces the pollution parameters in tofu industry wastewater with a reduction efficiency for BOD, TSS, and oil and greasel of 52-95%, 45-67%, and 59-78% respectively with concentration of 97 mg/L, 40 mg/L, and 4.2 mg/L at the detention time of 15 days. This results fulfill the requirement of the liquid waste standard according to the Minister of Environment Regulation No. 5 year 2014.AbstrakLimbah cair industri tahu mengandung bahan organik tinggi yang dapat menurunkan oksigen terlarut, mengotori, dan menimbulkan bau menyengat sehingga berpotensi mencemari perairan penerima.

Analisis data kualitatif digunakan untuk menganalisis data penelitian ini. Metode pengumpulan data dengan menggunakan kuesioner, wawancara dan focus group discussion. Hasil penelitian menemukan bahwa penerapan pengendalian internal pengelolaan keuangan sekolah di Kota Jambi sudah baik. Penerapan tertinggi pada unsur lingkungan pengendalian, sedangkan penerapan terendah pada unsur pemantauan. Penyebab SPI belum optimal diterapkan antara lain karena keterbatasan sumber daya manusia, keterbatasan auditor internal dan pengawas pengelolaan keuangan sekolah dan belum tertib dokumentasi penerapan SPI.
