Abstract

Air limbah dari operasional rumah sakit mengandung kadar yang dapat membahayakan kesehatan masyarakat dan lingkungan. Maka, air limbah itu perlu dikelola dengan IPAL supaya penuhi standar baku mutu sebelum air limbah dibuang ke badan air. Studi ini dilaksanakan di RS PKU Muhammadiyah Yogyakarta dengan mengumpulkan data pada IPAL eksisting dan dievaluasi. Hasil uji laboratoium pada inlet air limbah di RS PKU Muhammadiyah Yogyakarta yang memiliki COD yakni 104,5 mg/L, BOD 53,1 mg/L, TSS yakni 81 mg/L, pH yakni 7,62, dan suhu yakni 30,4 °C. Hasil uji air limbah pada outlet IPAL eksisting masih memenuhi syarat baku mutu Peraturan DIY No. 7 Tahun 2016 Tentang Baku Mutu Air Limbah, namun IPAL eksisting masih mengandung lumpur yang tinggi. Sehingga, diperlukan perancangan ulang desain IPAL dengan kelayakan bangunan 10 tahun kedepan dengan sistem IPAL rencana ialah anaerob dan aerob dengan metode DEWATS. Komponen IPAL yang didesain ialah grease trap, bak ekualisasi, bak pengendap awal/settler, anaerobic baffled reactor, anaerobic filter, aerobic ponds, dan polishing pond. IPAL yang direncanakan menghasilkan COD effluen yakni 3,67 mg/L, BOD effluen yakni 1 mg/L, dan TSS effluen yakni 1,54 mg/L yang sudah penuhi standar baku mutu Peraturan DIY No. 7 Tahun 2016 Tentang Baku Mutu Air Limbah.

Abstract

The study namely Drought Analysis Using Various Drought Indices in District Ngemplak, Boyolali offers a comprehensive examination of drought phenomena in the Ngemplak, Boyolali district through the lens of var­ious drought indices, aiming to understand the impact on agricultural productivity and propose effective water management strategies. Using data from 2009 to 2023, this study used SPI and PDSI.  Focusing on the Ngem­plak, Boyolali district, this research identifies the most relevant drought indices tailored to the local climatic and geographical contexts, analyzes the correlation between these indices and the productivity of primary crops, and suggests sustainable water management practices to mitigate drought risks. The study underscores the importance of adopting a multifaceted and adaptive water management framework, incorporating sophisticated irrigation technologies, and fostering policy reforms to enhance water use efficiency and resilience against climatic variability. It calls for collaborative efforts involving stakeholders across different sectors to implement these recommendations, ensuring the sustainability of water resources and agricultural productivity in the face of drought challenges.
