Peat water is surface water in swampy or lowland areas that has a high color intensity, low pH (3-5) and strongly metals’ bonded. In proper treatment, the existence of peat water can meet the needs of the surrounding community. Additionally, keeping clean water or drinking water can be helped by the alternative treatment of peat water. Peat inorganic ceramic membrane which can be in accordance with water quality based on the Regulation of the Minister of Health of the Republic of Indonesia Number: 492 / Menkes / Per / IV / 2010. Ceramic membrane made from clay and modified with activated carbon and zeolite in such way turned out to be able to produce drinking water in accordance with drinkable water standards. This study aims to determine the membrane’s ability to treat peat water and determine the magnitude of turbidity reduction, total dissolved solid (TDS), pH, Fe and Mn and E. coli bacteria. This research was carried out by filtering peat water through the membrane. Membranes was made of tubes with specifications used are 7 cm high and 6.8 cm in diameter and 0.8 cm wide with various mixture of clays, activated carbon and zeolites. The compositions are 80; 10; 10; 70; 20; 10; 60; 30; 10, 50; 40; 10, respectively, and 140 mesh active carbon size variations. After the investigation, it turns out that all of the composition 80; 10; 10 (clay: activated carbon: zeolite) with a combustion temperature of 800°C is the best membrane removal result that produces standards drinkable water content with clear color intensity.

The increasing population of modern cities contributes to the development of more residential high-rise buildings as well as waste management challenges. Recycling and waste separation can be a challenge in high rise apartment buildings due to the high volume of residents and limited space for waste management. Therefore, the objectives of this study is to investigate the knowledge, attitude, and challenges of high-rise building communities towards waste segregation and recycling. Using cross-sectional analysis, online questionnaires were distributed to target respondents in Sentul Kuala Lumpur. Data were collected from 375 residents of high-rise buildings. The results show that the high-rise community has modest knowledge (57%) and challenges (61%) to practice waste sorting and recycling, however, showed a good attitude (81%) towards it. Waste separation and recycling were influenced by sociodemographic factors of education (p = 0.05), ownership (p = 0.02), marital status (p = 0.01), and floor of living (p = 0.02). There is positive correlation between knowledge an attitude (r = 0.57, p = 0.26), but negative correlation between knowledge and challenges (r = - 0.25, p = 0.0001). The result also indicates that this community lack information and knowledge to practice waste sorting and recycling. Intervention is required to convey the information to these dwellers.

Ceramic membrane is one of technology membrane which used as a filtration. Filtration process is the easy way to solve the problem for water purification. Ceramic membrane was used as filtration for peat water. Peat water is the surface water of peat soils that contain high organic matter as well as high enough iron, acidic taste with a pH of 3-5 and a low level of hardness. Therefore, one of the managements of peat water is by using ceramic membrane. The goal of this study is making ceramic membrane from clay, zeolite and activated carbon as a filter for peat water. The research was conducted by using ceramic membrane with composition ratio of 80:10:10; 70:20:10; 60:30:10; 50:40:10, respectively, with the temperature of combustion varied from 600, 700 and 800 Degree Celsius, respectively. The ceramic membrane applied as a filtration for peat water. The permeats from filtration process using ceramic membrane had been analyzed parameter which indicate the good quality of peat water. This study obtained the highest Fe2+ removal efficiency in peat water by 100 percent, the highest Mn2+ removal efficiency of 99.94 percent, followed by a TDS removal efficiency of 82.58 percent and turbidity 95.65 percent.
