Waste can cause problems that until now have not been resolved in waste management. Waste management that has not been implemented optimally can later affect the condition of the surrounding environment. Waste that has not been managed properly and the increasing rate of waste generation can reflect the existence of a waste management system that has not been carried out effectively and still requires a structured waste management method.The aim of this research is waste management, which collects, transports and disposes of waste, now will change to a new paradigm through management at the place of origin or waste management site in the form of a Waste Processing Facility (TPS) using the Reduce, Reuse, Recycle (3R) Method.The results of this study indicate that the amount of waste generated in the Rajawali Reseidence housing complex is a waste weight of 0.025 kg/person/day and a waste volume of 2.934 liters/person/day. The composition of waste produced in the BTN Rajawali Residence housing complex is, plastic waste of 0.814 kg/person/day, wood and garden waste of 0.151 kg/person/day, B3 waste of 0.317 kg/person/day, food waste of 3.904 kg/person/day, paper waste of 0.489 kg/person/day, textile waste of 0.000335 kg/person/day, metal waste of 0.0097 kg/person/day and glass waste of 0.107 kg/person/day. Evaluation of operational techniques for waste management in BTN Rajawali Residence housing based on SNI 19-2454-2002, namely, the container is appropriate but individual containers must be improved again, Collection is appropriate (collection is carried out routinely), transportation is appropriate (TPS waste is transported to TPA), waste transfer requires an effective schedule and good route, processing is not appropriate (must be more comprehensive for both organic and inorganic waste), final disposal (TPA is not explained in detail, but there are opportunities for development to increase efficiency and reduce environmental impact). In general, this system has met the standards set for operational aspects. However, there are some that need to be improved.

Clean water is a fundamental necessity for community life, directly impacting health, economy, and social welfare. The availability of continuous and quality clean water is a major challenge for regions experiencing rapid population growth, such as Angsana District. Sustainable clean water supply in Angsana District is constrained by the insufficient capacity of the existing reservoir (300 m³) to meet the continuously increasing demand due to population growth. This study aims to: (1) project clean water demand for the next 20 years (2024–2043); (2) determine the required reservoir capacity; and (3) design an appropriate additional reservoir. Using a quantitative approach, population projection was conducted using the geometric method, while water demand was calculated based on domestic and non-domestic needs in accordance with Indonesian National Standards SNI 7509:2011 on Technical Planning Procedures for Drinking Water Supply Systems and SNI 6774:2023 on Planning Procedures for Package Unit Water Treatment Plants. The results show a population growth rate of 2.26% per year, with a projected population of 36,672 people by 2043. Peak hour water demand is 105.7 liters/second, and maximum daily demand (Qhm) is 5,333.3 m³/day. According to SNI 6774:2023, the required effective reservoir capacity is 15% of Qhm, which is 800 m³. Considering the existing 300 m³ reservoir, an additional reservoir with a capacity of 500 m³ is needed. The proposed technical design for the ground storage reservoir is rectangular with dimensions of 15 m (length) × 10 m (width) × 3.33 m (total height), an effective water height of 2.83 m, and includes freeboard and dead storage.

Wastewater is water resulting from human activities that contains compounds that are harmful to humans. In addition, waste can also cause irritation, poisoning, genetic mutations, and cancer in humans, especially in Baruga District, Kendari City. Therefore, in the wastewater management process, there needs to be a handler whose goal is to determine whether the waste is hazardous or not, so that appropriate treatment steps can be implemented to overcome any negative impacts that may arise. The process of managing domestic wastewater and waste characteristics needs to be carried out using data analysis techniques that include quantitative and qualitative approaches. Sampling was carried out in one of the water bodies in Kendari City. The sampling procedure refers to SNI 6989.59:2008 concerning sampling procedures. The results of laboratory testing of domestic wastewater samples from Baruga District, Kendari City, Southeast Sulawesi Province found that five of the seven test parameters exceeded the quality standards stipulated in the Regulation of the Minister of Environment No. 68 of 2016, namely TSS (510 mg/L), pH (5.17), COD (128 mg/L), BOD (36.70 mg/L), and Total Coliform (8,200 CFU/100 mL). Meanwhile, the parameters of Ammonia (4.90 mg/L) and Oil & Fat (0.19 mg/L) are still within the permitted limits.

Pengaruh Suhu dan Lama Penyimpanan Air Isi Ulang terhadap Kualitas Air Minum

2026-02-23T14:34:54+00:00

Refillable drinking water is a source of drinking water widely used by the public, especially in urban areas, because it is more affordable than bottled water. However, the quality of refillable drinking water is often a concern, because it can be affected by various factors, such as the quality of the water source, the processing process, and storage and distribution methods. This study aims to examine the effect of temperature and storage duration on drinking water quality in refillable water. Good drinking water quality is very important for health, but is often affected by improper storage factors. This study used an experimental approach with variations in indoor and outdoor storage temperatures and storage durations (1, 3, and 6 days). Refill water samples were taken from a refill drinking water depot in the BTN area. Aldzaky Residence, Anduonohu Village, Poasia District, Kendari City, Southeast Sulawesi Province, then tested for quality based on physical, chemical, and microbiological parameters, including pH, odor, taste and color, E-coli bacteria content and iron metal content. The results showed that storage temperature and storage time significantly influenced drinking water quality. The higher the storage temperature and the longer the storage time, the water quality tended to decline, especially in bacteriological parameters and heavy metal content. This decline in quality has the potential to harm consumer health if not stored properly. Based on these findings, it is recommended that refill water be stored at a lower temperature and consumed within a short time to maintain its quality.
