The by-product of sludge generated at the Water Treatment Plant can affect water quality degradation if disposed of directly without any prior treatment. As a company engaged in water management, the urban drinking water companies produce sludge in every production activity. This study aimed to identify the flow of sludge generation at the Water Treatment Plant, the quantity of sludge generated at the sedimentation unit, and the quality of the wastewater generated at the Sludge Treatment Plant. The identification results show that the flocculation, sedimentation, and filtration units produce sludge transported to the sludge treatment unit (SCP and SDB). The quantity of sludge generated in the sedimentation unit in March and April are 1,887m3/day and 1,474m3/day, respectively. The physical and chemical quality (pH, temperature, TDS) of wastewater produced by the sludge treatment unit are still below the quality standard based on PERMENLHK No. 5 of 2014, concerning Wastewater Quality Standards for Businesses or Activities That Do Not Have Wastewater Quality Standards.

Instalasi pengolahan air limbah (IPAL) industri tapioka di Kabupaten Lampung Timur Provinsi Lampung menggunakan kombinasi UASB dan tangki aerasi. Air limbah kemudian diolah lebih lanjut pada kolam stabilisasi. Pada saat ini seluruh kolam stabilisasi tidak menggunakan pelapis membran ataupun tanah lempung. Hal ini dinilai mencemari air tanah di daerah sekitar pabrik. Air limbah yang dilepas ke badan air juga masih melebihi baku mutu. Sehingga perlu dilakukan evaluasi unit bangunan eksisting dan memberikan solusi atas hasil evaluasi ini. Evaluasi dilakukan dengan melakukan komparasi kondisi eksisting dengan kriteria desain unit IPAL. Hasil study menunjukan bahwa beberapa kriteria seperti waktu detensi, organic loading rate, velocity, dan dimensi pada beberapa unit tidak sesuai. Solusi yang diberikan atas pencemaran air tanah adalah penutupan kolam stabilisasi dan menggantinya dengan kombinasi unit anaeobic baffled reactor (ABR) - facultative pond. Instalasi tersebut dinilai mudah dan murah dalam pengoperasian dan perawatan. Data kualitas dan kuantitas air limbah didapat dari kombinasi data primer dan sekunder. Data yang didapat dijadikan acuan untuk perencanaan detail engineering design IPAL pengganti kolam stabilisasi. Perhitungan biaya untuk IPAL dan perpipaan mengacu pada Standar Nasional Indonesia dan Harga Satuan Pokok Kerja (HSPK) Kota Bandar Lampung. Setelah dilakukan perhitungan terhadap biaya pembangunan ABR dan kolam fakultatif, diperlukan biaya sebesar Rp. 761.313.124.

Waste is a very complex and urgent problem to be solved. The problems occur due to the participation of the residents as the leading actor. This study aimed to determine the significance of the influence of gender, age, education, employment status, income, duration of stay, and the level of knowledge on waste generation and management. Respondents to questionnaires and interviews were 37 people whose numbers were determined based on the Slovin equation, while data was analyzed using SPSS Statistics 20 software. A person's educational status significantly positively affects people's habits in reducing waste generation. The following positive significance was income, gender, and length of stay. Age and employment status have a negative correlation, indicating that the older and working, the less waste the society generates. Besides affecting waste generation, it turned out that education also significantly affects waste management. Therefore, education is the main factor considered in waste planning. The results of this study can be used as input for the Indonesian Government in providing information through training and the provision of waste management facilities.

Rubber industrial wastewater is obtained during washing, shredding, grinding, crumbbing, drying, and pressing bokar. The wastewater produced can be an environmental pollutant because it contains relatively large amounts of organic matter. One alternative to treating rubber wastewater is to use the electrocoagulation process, which is a combination of the coagulation and electrolysis processes. This electrocoagulation process has several advantages in the form of simple equipment, short time, produces odorless wastewater, does not require large areas of land, and can remove various contaminants in water. In this study, rubber wastewater was treated by electrocoagulation using a batch system with variations in the contact time used, namely 20, 40, 60, 80, and 100 minutes. This type of research is experimental research, and descriptive analysis is carried out. Rubber wastewater is physically gray-black before treatment and chemically contains large organic matter. The results of this study showed that the content of chemical oxygen demand (COD) and total suspended solids (TSS) before processing had values of 691 mg/L and 317 mg/L. Optimum conditions for the elimination of COD and TSS contents were achieved within 80 minutes with the percentage of elimination being 89% and 85%.
