Abstract

Latar belakang: Batik merupakan warisan budaya Indonesia yang nilai ekspornya meningkat pesat. Dampak ini dapat meningkatkan pendapatan negara secara signifikan. Di sisi lain, memperluas kesempatan kerja bagi masyarakat untuk memproduksi batik. Namun , produksi batik yang besar meningkatkan volume limbah. Permasalahan ini dapat mencemari lingkungan jika limbah batik tidak terurai dengan baik. Oleh karena itu, kami mengusulkan metode bioremediasi untuk menguraikan polutan COD dalam limbah batik. Penelitian ini bertujuan untuk mengukur kemampuan MPMO dalam mereduksi COD pada limbah batik. Hasil penelitian terdahulu menunjukkan bakteri Bacillus licheniformis memiliki kemampuan mereduksi COD pada limbah tekstil. Selain itu, MPMO yang mengandung bakteri Bacillus licheniformis juga terbukti dapat menurunkan nilai COD pada IPAL industri gula.Metode: Penelitian ini dilakukan dalam skala laboratorium, dan menggunakan sistem batch untuk proses seeding dan aklimatisasi pada MPMO. Pada proses seeding menggunakan nutrien buatan untuk menumbuhkan mikroorganisme. Proses aklimatisasi menggunakan % v/v campuran limbah batik dan nutrien buatan sebagai proses adaptasi mikroorganisme terhadap limbah. Parameter selama proses seeding dan aklimatisasi yaitu COD, pH, MLSS, dan MLVSS. Pengambilan parameter COD dilakukan setiap 0 jam pada influen dan 24 jam pada efluen reaktor.Hasil: Nilai CODinfluen, CODefluen, Efisiensi penyisihan COD, pHawal, pHakhir, MLSS, dan MLVSS yang diperoleh selama proses aklimatisasi masing-masing antara 1145-3084 mg/L, 354-1268 mg/L, 54-82%, 6.43-8.25, 7.33-8.32, 790.5-2356.5 mg/L, 0.454-1.657 mg/L.Simpulan: Penggunaan MPMO dengan bakteri Bacillus licheniformis dapat menyisihkan COD limbah batik pada proses aklimatisasi sebesar 82% dengan nilai rata-rata efisiensi penyisihan COD sebesar 65%. ABSTRACT Title: Reduction of COD Concentration from Batik Waste Water Treatment in Seeding and Acclimatization Process Using Microorganism Preservation Materials (MPMO) Background: Batik is an Indonesian cultural heritage whose export value is increasing rapidly. This impact can increase the state's income significantly. On the other hand, it expands job opportunities for people to produce batik. However, large batik production increases the volume of waste. This problem can pollute the environment if the batik waste is not decomposed properly. Therefore, we propose a bioremediation method to decipher the pollutant COD in batik waste. This research aims to measure the ability of MPMO in reducing COD in batik waste. The results of previous studies showed that Bacillus licheniformis has the ability to reduce COD in textile waste. Moreover, MPMO containing Bacillus Licheniformis bacteria also can decrease COD in the sugar industry WWTPs.Method: This research was conducted on a laboratory scale with the sample pollutants from the batik production in Yogyakarta. We used a batch system for the seeding and acclimatization process in MPMO. During the seeding process, nutrients are used to grow microorganisms. The acclimatization process uses a % v/v mixture of batik waste and nutrients as a process of adapting microorganisms to waste. Parameters of the seeding and acclimatization were recorded during the process, such as COD, pH, MLSS, and MLVSS. For COD, the parameter was taken every 0 hours on the influent and 24 hours on the effluent reactor.Result: The values of CODinfluent, CODefluent, COD removal efficiency, initial pH, final pH, MLSS, and MLVSS obtained during the acclimation process were respectively 1145-3084 mg / L, 354-1268 mg / L, 54-82%, 6.43- 8.25, 7.33-8.32, 790.5-2356.5 mg / L, 0.454-1.657 mg / L.Conclusion: The use of MPMO with Bacillus licheniformis bacteria can remove COD from batik waste in the acclimatization process by 82% with an average COD removal efficiency of 65%.

Abstract

The addition of phosphate-solubilizing microorganisms (PSM) as biofertilizers can improve the quality of soil properties. A meta-analysis study was conducted to analyze the effect of PSM on soil properties. This meta-analysis has analyzed 20 research articles published between 1990 and 2023, which have reported the influence of PSM on soil properties. The value of effect size (ES) Hedges'd of available-P is 3.047 (p<0.001), ES of available K is 2.102 (p<0.001), ES of soil nitrogen (N) is 1.706 (p<0.001), ES of pH is  -2.738 (p<0.001), ES of soil organic carbon (SOC) is 1.087 (p=0.004), ES of N-NH4 is 0.636 (p= 0.013), ES of N-NO3 is 2.643 (p< 0.001), ES of phosphatase is 5.001 (p< 0.001), ES of alkaline phosphatase is 22.956 (p<0.001), and ES of acid phosphatase is 23.104 (p<0.001). The results showed that in terms of phosphate solubility, PSM is more effective on alkaline soils with high SOC content, very high P availability, and a sandy loam texture. PSM is more effective for K solubility on acidic soils, with very high SOC content, high P availability, and a loamy texture. PSM is effective in increasing soil N with acid soil characteristics, low SOC content, moderate available P content, and clay texture. According to this study, the Penicillium fungus ranks second in the fungal group in terms of phosphate solubilization capacity after the genus Azotobacter. The genus Peronospora showed the greatest potential in increasing soil N. In contrast, Burkholderia showed the greatest effectiveness in solubilizing K.
