Abstract

Rumah sakit menghasilkan limbah padat, cair, dan gas yang berpotensi mengandung mikroorganisme penyebab penyakit, bersifat infeksius, serta mengandung bahan kimia berbahaya maupun zat radioaktif dalam kadar kecil yang berdampak negatif terhadap kesehatan manusia dan lingkungan. Pengolahan limbah berperan penting dalam mengurangi sifat berbahaya serta memastikan kualitasnya sesuai standar sebelum dibuang ke lingkungan. Penelitian ini bertujuan mengevaluasi sistem operasional serta pemeliharaan Instalasi Pengolahan Air Limbah (IPAL) Rumah Sakit X, berdasarkan Buku 3 Pedoman SOP UPTD Pengelola Air Limbah Domestik Tahun 2018 dan Peraturan Gubernur Jawa Timur No. 72 Tahun 2013. Metode yang digunakan adalah dengan cara melakukan observasi, wawancara dengan pengawas operator dan juga melakukan dokumentasi unit pengolahan di IPAL. Hasil evaluasi menunjukkan bahwa sistem pengolahan limbah telah berjalan sesuai prosedur, di mana efisiensi penyisihan parameter pencemar untuk kadar BOD, COD, TSS, dan mikroorganisme patogen memenuhi baku mutu. Pengelolaan IPAL secara rutin dan pencatatan parameter harian juga telah dilakukan dengan baik. Kesimpulannya, hasil evaluasi menunjukkan bahwa tingkat kesesuaian operasional IPAL terhadap Peraturan Gubernur Jawa Timur Nomor 72 Tahun 2013 mencapai 100%. Berdasarkan dengan Buku 3 SOP Aset Operasi UPTD, tingkat kesesuaian operasional tercatat sebesar 93,3% dengan 28 dari 30 parameter terpenuhi, sedangkan tingkat kesesuaian pemeliharaan sebesar 89,65% dengan 26 dari 29 parameter terpenuhi.

Abstract

Wastewater from the palm oil production process contains high levels of organic matter, so the appropriate treatment to remove organic matter is anaerobic processing. At PT XYZ, several types of reactors are used in the anaerobic process, including Upflow Anaerobic Sludge Blanket (UASB), Expanded Granular Sludge Blanket (EGSB), Internal Circulation (IC) Tank, dan Super Internal Circulation Tank. The bacteria used are generally granular in shape, which settle more quickly, but in field conditions, the bacteria used for UASB are sludge powdering, which tends to wash out. This can reduce the efficiency of wastewater treatment. The purpose of this study is to analyze the formation of granular sludge from sludge powdering in UASB reactors. The method used was experimental using a beaker glass reactor operated for 6 weeks. The principle of coagulation flocculation was used with the addition of 0.3 g/L/hr of urea as nutrients for bacteria and FeCl3 as a binding agent. The stages of this study included sampling, reactor operation, observation & treatment, and data analysis. The results showed that the UASB reactor did not form granular sludge, because the sludge produced was in the form of fine flocs. The addition of FeCl3 and urea caused the pH value of the reactor to fluctuate and tend to be alkaline, resulting in conditions that were not optimal for the activity of granular-forming bacteria. Therefore, granular sludge was not obtained from the experiment using UASB sludge powdering with a glass beaker reactor.

Abstract

Polystyrene is a type of plastic that is difficult to decompose naturally and  one of the main causes of environmental problems, especially in Indonesia, styrofoam waste in 2023 reached more than 32 million tons per year. This study uses quantitative descriptive and experimental methods to determine the ability of Bacillus subtilis bacteria to decompose polystyrene waste. The quantitative descriptive method was carried out by measuring the decrease in dry weight of polystyrene, while the experimental method was carried out by incubating 1x1 cm and 2x2 cm polystyrene samples with B. subtilis in Bushnell Haas media at 37°C for 40 days, with observations performed every 10 days. In addition, chemical changes in polystyrene were observed using Fourier Transform Infrared (FTIR) to see changes in functional groups. The results showed that the 1×1 cm sample experienced a weight loss of up to 20.65% after 40 days, while the 2×2 cm sample only decreased by 8.70%. FTIR analysis showed changes in absorption intensity and the appearance of carbonyl (C=O) and hydroxyl (O–H) groups, indicating the occurrence of oxidation and polymer chain cleavage. In conclusion, Bacillus subtilis was able to degrade polystyrene gradually, with effectiveness influenced by the size of the sample surface and the length of incubation time.
