Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Urban water management efforts are essential in encouraging the fulfillment of the SDGs targets. One action that can be done is to approach the calculation of the actual water consumption value. This research conducted a survey of domestic water consumption in Bandar Lampung City to obtain comprehensive information. Bandar Lampung City was chosen because it is one of the cities on the island of Sumatra with a high economic growth rate. Lampung Province is the top 3 province in Sumatera Island with the higher Gross Domestic Product Growth on 2022, with Bandar Lampung as its capital city. Furthermore, water consumption patterns were analyzed for various activities, socio demographic conditions, and the community's economy. The results showed that of the 404 samples, the average water usage was 195.08 liters/person/day, with the dominant activities in use including bathing (66.84 liters/person/day), flushing the toilet (35.71 liters/person) / day), and ablution (29.74 liters/person/day). Furthermore, the variable number of family members in one house and income level have significant different on total domestic water consumption. The results obtained in this study are expected to assist in making decisions regarding urban water management plans.

Abstract

global warming and environmental issues are being caused by the overuse of fossil fuels and increased industrialization around the world, which has resulted in the production of greenhouse gases. As a result, it's crucial to reach net-zero carbon emissions. By balancing the total quantity of carbon dioxide or other greenhouse gas emissions over a specific period and taking actions that are ecologically responsible, net zero carbon emissions can be accomplished. For environmental sustainability to be successful, it must be able to influence people's attitudes and behavior toward the environment. To understand NGOs' obligations in supporting net-zero carbon emissions, this paper presents a methodical debate utilizing NGOs as case studies. The method is employed in this work by reviewing the body of primary and secondary research on the study issue. This essay initially lists different environmental NGOs organizations before categorizing and outlining some of the significant GHGs reduction initiatives made by these organizations. This essay also addresses key issues that must be addressed upon to achieve the best outcomes. This report gives a broad overview of the synergizing domains that NGOs around the globe work in to assist improvement environmental security.

Abstract

One of the most widely used fuels is coal, where the South Sumatra region is an area with coal potential whose production is still being increased. On the other hand, there are negative impacts caused by coal exploration activities, one of which is mining runoff, commonly called acid mine drainage. Acid mine drainage has a low pH and contains inorganic constituents such as iron and manganese. Therefore, proper and optimum information processing is needed to support environmentally friendly mining management. In contrast, alternative materials such as blast furnace slag, wood ash, fly ash, cement kiln dust, and construction waste are being used. These materials are effective against AMD, at a relatively low cost, and outperform traditional neutralizers. However, comparing them with conventional agents is challenging due to limited data and experimental variation. In this study, the objectives to be achieved are 1) to determine the quality conditions of AMW at the study location, 2) to determine the effectiveness of the use of chemical and alternative compound neutralization agents in the processing process, and 3) to provide recommendations for the dosage, type of neutralization agent, and the most optimum time in AMW processing. The AMW obtained is then subjected to laboratory analysis related to quality, including TSS, pH, Fe, and Mn parameters. In addition, conventional and alternative neutralization agents are also prepared and then used to process AMW. Then, experiments were carried out on variations in the type of neutralization agent, the dosage of neutralization agent use, and the contact time between the neutralization agent and AMW. Experimental results have shown that these materials, mainly pond ash and concrete sludge, can effectively neutralize pH and reduce Mn concentrations by up to 83.26% and 79.12%, respectively. Similarly, Fe concentrations can be reduced by up to 80.76% and 74.05% using pond ash and concrete sludge, respectively. While these results are promising, future research should focus on characterizing the generated sludge to confirm the adsorption of ferrous and manganese ions onto the surface of the alternative neutralizers.

Abstract

Climate change that is happening at this time affects the decrease in the availability of water in the world. Urban areas, especially coastal areas, will have a more significant impact on water scarcity. Coastal areas in Indonesia, such as Bandar Lampung City, are mainly concerned in this study. Therefore, a study was conducted to determine the variables that influence water conservation practices in Bandar Lampung, which focuses on social psychological factors with four independent variables. By knowing the independent variable that has the highest level of influence, an approach to conservation efforts at the individual level can be approached. Data were obtained using a closed questionnaire with answer options using a Likert scale. Data analysis used simple linear regression and stepwise regression. The simple linear regression results show that the variable social norms (X4) are the highest variable with a value of R2 0.0385. In stepwise regression, the variable attitude towards conservation (X1), the benefits obtained (X2), individual control behavior (X3), and social norms (X4) simultaneously have a coefficient of determination value of R2 0.06127, where the social norms variable align with sample linear regression results on water conservation practices. These social norms can be used as a reference by stakeholders such as Perumda, Regional Government, NGOs, etc., through individual approaches in mapping strategies for increasing water conservation practices.
