Abstract

In this study Mixture of domestic grey water and black water were investigated. This Mixture consists of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), and  Nitrate  (NO3).  This  research  investigated  the  influence  of  concentration  and  flow  variation parameters  to  treating  the  Mixture  Grey  Water  and  Black  Water.  Effluent  quality  of  decreasing concentration varied by the concentration and flow recorded BOD was about 102-544 mg/l, COD was about 287-1.230 mg/l, TSS was about 280-780 mg/l and for treating  nitrate the result was fair enough than others was about 4-12 mg/l.  According to the flow variation resulted the retention time are 4, 6 and 8 hours. The best effluent quality was happened 878 mg/LCOD, and varied by flow are 0,125. The results  of  research  showed  the  higher  concentration  will  decrease  the  value  of  BOD  and  Nitrate removal, due to the influence of pH.The higher flow will decrease the value of BOD and increase COD, TSS, and Nitrate removal, and  optimum flow condition was 0,125 l/hour.

Abstract

Pengolahan air limbah PT. Indofood CBP menghasilkan sludge yang belum terolah dengan baik. PT. Indofood membutuhkan suatu teknik pengolahan sludge sebagai wujud komitmennya terhadap lingkungan. Tujuan penelitian ini adalah untuk mengetahui kondisi optimum pengomposan aerobik sludge dan kulit bawang. Kulit bawang yang digunakan adalah, yaitu kulit bawang dari divisi pengupasan bawang PT. Indofood CBP. Pada penelitian ini dilakukan analisis terhadap kandungan C-Organik, N-Total, P-Total, K-Total, C/N rasio, dan kadar air pada kompos tiap lima hari sekali. Hasil penelitian didapatkan C/N rasio aktivator EM4 adalah variasi A1 (2,5 kg sludge + 2,5 kg kulit bawang) sebesar  19,74%, B1 (3,3 kg sludge + 1,7 kg kulit bawang) sebesar 18,61% dan C1 (4,2 kg sludge + 0,8 kg kulit bawang) sebesar 14, 17%. Sedangkan C/N rasio aktivator lumpur aktif adalah variasi A2 (2,5 kg sludge + 2,5 kg kulit bawang) sebesar 19,81%, B2 (3,3 kg sludge + 1,7 kg kulit bawang) sebesar 19,00%, dan C2 (4,2 kg sludge + 0,8 kg kulit bawang) sebesar 14, 76%. Hal ini menunjukkan bahwa semakin banyak penambahan lumpur, semakin baik C/N rasio kompos.

Abstract

Teknik pengomposan keranjang takakura telah banyak digunakan oleh rumahtangga di berbagai kota-kota besar di Indonesia. Pada sisi operasional terdapat kendalameliputi menurunnya efektifitas kinerja penguraian sampah organik sehingga seringterjadi kegagalan proses. Oleh karena itu, diperlukan suatu cara sederhana dalammeningkatkan kinerja porses pengomposan metode takakura. Secara garis besar,tahapan penelitian dibagi menjadi tahap persiapan, tahap pengomposan, dan tahappengolahan data. Penambahan sekam dan bekatul divariasikan ke dalam lima kotakkeranjang. Inokulum dalam komposter yang digunakan diambil dari keranjang milikmayarakat. Hasil penelitian menunjukkan penambahan sekam dan bekatul pada variasi3. 4, dan 5 belum menunjukkan hasil signifikan dalam meningkatkan kinerja inokulumseperti kotak 1. Temperatur inokulum baru masih di atas temperatur variasi/kotak yanglain. Hal ini disebabkan pada inokulum baru dimungkinkan masih terdapatmikroorganisme aktif serta sisa makanan dan sirkulasi udara yang baik. Namun jikadibandingkan satu persatu, penambahan sekam dan bekatul mampu menaikkantemperatur pada awal penelitian dibanding kotak 2 pada rata-rata proses. Penambahanbekatul dan sekam menyebabkan peningkatan rasio C/N. Namun, peningkatan rasio C/Ntidak serta merta membuat kotak 2, 3, dan 4 memiliki proses degradasi yang lebih baikdaripada inokulum baru yang ditandai dengan temperatur. Kandungan Karbon, Nitrogen,Phospor, dan Rasio C/N keseluruhan kompos matang telah memenuhi standar dalamSNI 19-7030-2004, standar internasional, dan Departemen Pertanian, tetapi masih belumsesuai dengan standar Departemen Pertanian dan PT.

Abstract

The crisis in clean water availability due to population growth, industrialization, and climate change has driven the need for more effective and sustainable wastewater treatment technologies. Plasma technology is emerging as a potential solution capable of overcoming the limitations of conventional methods, especially in the degradation of complex pollutants and new polluting compounds. Aim: This study aimed to identify trends, developments, and research gaps related to the application of plasma technology in wastewater treatment during the period 2000-2024. Methodology and results: A bibliometric analysis was conducted to map the publication trends, most influential sources, and research networks, while qualitative content analysis was used to classify research themes and highlight key findings from the selected papers. One hundred sixty-five papers on plasma technology application in wastewater treatment were retrieved from four databases and analyzed. The results show that research in this field is categorized into four main themes: plasma-based pollutant degradation, plasma-enhanced oxidation processes, energy-efficient non-thermal plasma reactors, and dielectric barrier discharge (DBD) for environmental treatment. Furthermore, the research focus has shifted from basic plasma exploration to applying plasma technology for water treatment and efficiency improvement. Conclusion, significance and impact study: This study provides recommendations for future research based on the findings of current research trends and themes, aiming to guide the development of more effective and sustainable plasma-based wastewater treatment technologies.

Abstract

Copper can be found in various equipment, building materials, and consumer products. When buildings are used, copper can enter wastewater in different ways. It is challenging for occupants to remove copper physically or chemically since they can potentially reduce copper levels through yard phytoarchitecture. This study aims to formulate houseplants' suitability to become decorative plants for the yard phytoarchitecture, simultaneously as onsite sanitation. This study identified the copper deconcentration pathway in wastewater by studying published works-based research. Literature was collected and selected based on recency, accessibility, and the relationship among copper, wastewater, and plants. The study findings show that processing copper by plant has the greatest opportunity to be implemented on a building scale. The yard phytoarchitecture system involves arranging plants in the yard, which serves both as a decorative feature and a way to treat the building's wastewater. It can be used on dry yards or ponds and only requires a small amount of land. The plants used should have low leaf density and high root density. It plays a dual role consisting of onsite sanitation infrastructure and yard aesthetics, which mutually strengthen the environmental health locally and positively effect on a larger scale.

Abstract

Various ambient air contaminants can spread into the indoor building through air transport. With the additional generation of contaminants from indoor activities, indoor air quality (IAQ) has the potential to be polluted. Indoor air pollution incidents can occur anytime, which is difficult to predict. Therefore, it is necessary to take action to improve IAQ as early as possible and sustainably. The solution to sustainable remediation is using plants to apply phylloremediation, which functions as leaves and leaf-associated microbial communities to reduce air contaminants. This study aims to provide new practical yet essential criteria for the sustainable operation of phylloremediation. This review is based on the latest results of a literature-based study. An analysis of the fundamental processes of plant life forms the basis for obtaining these criteria. The study emphasizes key criteria for phylloremediation encompassing the selecting plants with high transpiration and leaf-microbe synergy, and conducting maintenance by spraying water on leaves. These measures optimize efficiency and sustain the process for indoor air pollutant reduction. The final result summarises the new criteria for sustainable phylloremediation to maintain plant life. These essential criteria can be used for conducting experiments in empirical research, indoor design, and education for the community.
