Abstract

Balikpapan City is a city that does not have a large river to supply raw water like in several other cities, so to meet the water needs of the community, the main source of raw water is obtained from surface water from the Manggar Reservoir. The presence of high amounts of organic contaminants such as BOD and COD will affect water quality if treatment is not carried out to reduce these pollutants. One of the efforts that can be made to reduce pollutant levels is by the adsorption process using natural adsorbents, namely activated carbon from cassava peels. This research was conducted to find out how the effect of mass, contact time and the effectiveness of adsorbents from activated carbon of cassava peels in reducing BOD and COD levels in Manggar reservoir water, Balikpapan City. The adsorption process was carried out using variations in mass of 1, 3, 5, 7 and 9 gr and contact time variations of 30, 45, 60, 75 and 90 minutes. Based on the results of the study, the efficiency of reducing the BOD concentration of the adsorbent of activated carbon from cassava peels was 95.06% from the initial concentration of 8.3 mg/L to 0.41 mg/L at the optimum mass of 5 grams and the efficiency of reducing the COD concentration was 100% of the initial concentration of 28.54 mg/L to 0 mg/L at an optimum mass of 3 grams with a contact time of 30 minutes. From the results of the statistical analysis tests performed, it was found that the mass variation of the adsorbent did not significantly affect the decrease in BOD and COD concentrations, while the contact time had a significant effect only on the decrease in BOD concentrations.

Abstract

Bandung City is one of the highest solid waste-producing cities in Indonesia. Waste management needs to be organized so that the waste produced does not harm urban areas. One example of waste management is providing temporary waste storage sites (TPS) as intermediate transfer stations. One hundred fifty-six permanent TPS operates in Bandung, spread over 30 sub-districts with various conditions, both running well and unsuitable conditions affecting waste handling. This study aims to identify the condition of TPS waste management in the city of Bandung and evaluate it based on technical criteria for appropriate TPS buildings. The method for assessing the feasibility of TPS is assessed using 17 criteria, including criteria for TPS buildings and facilities. The evaluation was carried out at 44 TPS in Bandung. The evaluation results show seven criteria for transfer stations with a high degree of conformity and ten for a low level of conformity. The evaluation results resulted in the need for efforts to improve and develop TPS so that it can be used according to the criteria.

Abstract

Transfer Station is one of the most important parts of waste management operational aspects. The condition of Transfer Station container is often neglected whether it meets the standards based on SNI 19-2454-2002 and Minister of Public Works Regulation Number 3 of 2013 concerning waste containers. The container of Transfer Station can be seen from the characteristics of it such as the shape, nature and material. Waste problems in Karang Rejo Village are caused by several factors such as the decrease in quality, the distribution of Transfer Station points, and community’s behaviour in disposing the solid waste. This study aims to analyze the distribution and provision of Transfer Station, analyze community behavior in disposing of waste and evaluate Transfer Station in Karang Rejo Village based on community behavior in waste disposal. This research is a qualitative research, the research procedures carried out are observation, identification of the provision and distribution of Transfer Station, analysis of Transfer Station conditions in a descriptive qualitative way, distribution and collection of questionnaires, data processing and the evaluation stage of waste containers according to people's behavior in disposing of waste. The results showed that in Karang Rejo Village there were 16 Transfer Station units where the distribution of it, was disproportionate, in terms of supply there were 8 out of 16 Transfer Station units whose buildings were in damaged condition (percentage <60%), 99% of the behavior of the Karang Rejo Village community in disposing of garbage by how to get off the vehicle and throw garbage into the Transfer Station and 90% of the Karang Rejo Village community did not know information about waste containers. The evaluation results showed that the Transfer Station in Karang Rejo Village was not in accordance with the standards and there were 10 units that required total renovation, and 6 units requires the addition of components such as lids on containers.
