“…The concentration of COD has dropped since the sludge was inoculated with bacteria. It is proved that, due to the bacterial decomposition of organic compounds, a lower concentration of chemical oxygen demand [11]. Therefore, it was found that the COD level dropped dramatically after being inoculated for 14 days, 28 days, and sludge samples, with values of 586 mg/L, 579.3 mg/L, and 570.3 mg/L, respectively.…”

Fiberboard factories are rapidly growing to fulfill the increasing demand for timber production. Therefore, due to this rapid growth, there is a need to address wastewater sludge disposal concerns. This is crucial because the sludge contains a high concentration of contaminants that endanger the environment and public health. This study aims to treat the sludge by determining the potential of bacteria inoculation in the Solidification/Stabilization (S/S) method based on compressive strength, heavy metal leaching, and Chemical Oxygen Demand (COD) concentrations. The materials used in sludge remediation were Portland cement to act as a binder and Sphingobacterium spiritivorum. This study involves compressive strength testing, leaching tests using Toxicity Characteristics Leaching Procedure (TCLP), COD, and heavy metals concentrations analysis using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) equipment in accordance with U.S. Environmental Protection Agency guidelines (U.S. EPA). After bacteria inoculation, data shows an increase of approximately 4.4% in compressive strength test. COD concentration level reduces by around 1.5% but heavy metals concentration increases except for Chromium (Cr) and all elements still exceed the permissible limits. Based on the overall results, the method of bacteria inoculation in S/S method revealed the potential to remediate wastewater sludge.

“…Bio rings have a large surface area and porosity. The number of pores in the bio ring gives the bio ring a high surface area, which is helpful for bacteria to colonize, allowing water to enter the pores easily [37]. The disadvantage of this filter is that it cannot filter impurities from the dirt in the brackish water.…”

Indonesia, an archipelago with vast coastal areas consisting of 809 coastal villages, still faces the same problems of clean water scarcity and accessibility. This research goals are to discover appropriate inexpensive local filtering media and lower the salinity of brackish water in Sidoarjo Regency Indonesia. Regarding previous invention and research, this study deploy an experimental method by physical experiment including local materials along with chemical experiment: ion exchangers as well as reverse osmosis (RO). The outcomes demonstrate that local media filtration utilizing a combination of a 10-micron filter, kaolin, zeolite, kaolin, activated carbon, and kaolin is the best combination to produce the most transparent, and odorless water. It can reduce Total Dissolved Solid (TDS) and Electrical Conductivity (EC) values by 8.59% and 7.18%, and reduce pH levels by 2.59%. On the other hand, reverse osmosis and ion exchange can achieve 99.5% and 67% reductions in TDS and EC values, respectively.

“…Chemical Oxygen Demand adalah jumlah oksigen yang diperlukan untuk mengurai seluruh bahan organik yang terkandung dalam limbah, baik bahan organik mudah urai maupun yang komplek dan sulit urai akan teroksidasi. Sehingga selisih nilai antara COD dengan BOD memberikan gambaran besarnya bahan organik yang sulit urai yang ada di dalam limbah (Ariani, 2013). Jadi manfaat pemeriksaan COD adalah memberikan gambaran jumlah total bahan organik yang ada dalam limbah (Aristiana dan Purnomo, 2020).…”

Limbah peternakan sapi merupakan suatu sumber pencemaran lingkungan dan sumber penularan penyakit pada masyarakat. Munculnya pencemaran lingkungan dari suatu peternakan lebih banyak disebabkan karena limbah peternakan tidak ditangani dengan baik. Tujuan dari penelitian ini adalah untuk menganalisis unsur pencemar dan potensi penyebaran penyakit ke masyarakat. Penelitian ini menggunakan metode observasional dan purposive sampling yaitu sampel diambil dari empat kelompok ternak sapi tradisional Gianyar Selatan. Sebanyak satu liter sampel limbah diambil dari masing masing kelompok yang berbeda kemudian di bawa ke Laboratorium Kesmavet, Fakultas Kedokteran Hewan Universitas Udayana untuk dianalisis. Kandungan Total Suspended Solid (TSS), Ammonia, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Coliform with E. coli masing-masing dianalisis sesuai parameter uji menggunakan metode Gravimetric, Spectrophotometer, Winkler, titration-spectrophotometer, dan most probable number (MPN). Hasil penelitian menunjukkan bahwa nilai TSS adalah 26,75 mg/L, amoniak 7,86 mg/L, BOD5 171,817 mg/L, COD 605,675 mg/L, pH 8,075, Coliform 22 jt/100ml, dan kuman E. coli 20 juta/100ml. Disimpulkan bahwa limbah sapi pada penelitian ini sangat berpotensi mencemari lingkungan dan membahayakan kesehatan masyarakat karena mengandung zat zat kimia dan bakteri yang melampaui baku mutu yaitu parameter BOD5, COD, Coliform, dan E. coli. Dianjurkan untuk menangani limbah peternakan sapi dengan baik sesuai pedoman peternakan yang sehat untuk mengurangi pencemaran lingkungan dan ancaman kesehatan masyarakat.
