Abstract

Fresh or clean water is a primary need in housing life. Clean water is used in all housing activities starting from daily needs, they are food and drink; healthy needs for example taking a bath, washing and so on, it is included non primary needs for instance watering plant, washing motorcycle or car and etc. By Increasing population growth, housing need is higher so that many simple housing like Rumah Sangat Sederhana, RSS are established in suburb. Sometimes the location of housing is landfill of swam or field area. In Fulfilment of clean water, developer usually establish shallow well. For example Gelora Persada Housing, Rajabasa, Bandar Lampung. The quality of shallow well in farmer swam or field usually have high organic content that produce bad taste and smell, high turbidity, acid (low pH), and contain high iron (Fe) element. In research was conducted in shallow well of Gelora Persada Housing, Rajabasa, Bandar lampung by using rapid sand filter wich is completed by active carbon and zeolite as adsorbance so that gained to decrease turbidity level from 23,9 NTU become 6,51 NTU; can increase pH value from 6,24 to 6,44 and it also can decrease iron (Fe) content from 3,04 mg/lt become 0,74 mg/lt.

Abstract

Tujuan dari penelitian ini adalah: merancang alat pemurni air laut berdasarkan teori pemanasan, penguapan dan kondensasi menggunakan energi sinar matahari. Kegiatan penelitian dilakukan dengan mengamati data parameter berdasarkan 3 kombinasi perlakuan, yaitu; a) penggunaan kotak evaporasi yang memurnikan air setinggi 1 cm; b) penggunaan kotak evaporasi dan cermin cekung yang memurnikan air setinggi 1 cm; c) penggunaan kotak evaporasi, cermin cekung, dan kondensor yang memurnikan air setinggi 1 cm; Pengamatan selama 10 jam pemanasan di bawah matahari mulai pukul 07.00-17.00 WIB, memberi hasil bahwa ketiga kombinasi tersebut mampu memurnikan air laut menjadi air tawar. Kombinasi terbaik adalah kombinasi B, yang menghasilkan volume air tawar sebanyak 1.718 ml. Pengamatan lain yaitu nilai TDS menunjukkan bahwa penurunan nilai TSD air baku (air laut) dari 27.000 ppm menjadi 3 ppm hingga 5 ppm, sedangkan suhu air yang dihasilkan dari proses pemurnian menunjukkan nilai-nilai berkisar antara 27,5oC hingga 29,7oC, sedangkan pH air destilasinya berkisar di 5,024 hingga 5,252. Kata kunci : Air Bersih, Energi Surya , Pemurnian Air. The purpose of this research is : designing a water sea purifier tools based on the theory of heating, evaporating and condensing using sunlight energy. The research activity is done by observed data parameter based on 3 combination of treatment ; a) the use of evaporative boxes to purify seawater as high as 1 cm; b) the use of evaporative boxes and concave mirrors to purify seawater as high as 1 cm; c) the use of evaporative boxes, concave mirrors, and condensors to purify seawater as high as 1 cm; Observations for 10 hours of warming under the sun began at 07:00 to 17:00 pm, giving resulted that all combination are able to purify the seawater into fresh air. The best combination is a combination of B, which produces a fresh air volume of 1,180 ml. . The observation of the TDS value shown that a decline in the value of TSD raw water (seawater) from 27.000 ppm to 3 ppm until 5 ppm, while the temperature of the water produced shown values range between 27,5oC up 29,7oC, whereas pH of the destilated water around the 5.024 up to 5.252. Keywords: Fresh Water,Solar Energy , Water Purified

Abstract

Plastic waste is waste that cannot be decomposed so it will cause serious problems to the environment. The National Waste Management Information System (SIPSN) reported that in 2020 plastic waste was found to be 17.2% of the total waste collected. Several types of plastic can become porous charcoal through the heating process in a furnace so that it can be used as an adsorbent for liquid waste from the laundry industry. Laundry liquid waste containing excess phosphate will disrupt the environment such as eutrophication. This research aims to determine the effect of the HCl activator on carbon from polyethylene terephthalate (PET) plastic bottle waste to reduce phosphate levels in liquid laundry waste. This research uses varying concentrations of HCl as a carbon activator, namely 1M, 5M, and 10M. The activated carbon is added to the liquid laundry waste and stirred at a speed of 100 rpm. Phosphate content analysis was carried out using a spectrophotometer in liquid laundry waste before and after the adsorption process and BET (Brunauer-Emmet-Teller) analysis on activated carbon with activator HCl 10 M. The greatest decrease in phosphate levels was 10 M HCl concentration of 52.87%, with a carbon surface area of 203.1222 m²/g and a particle size of 29.53 nm. The adsorption capacity of activated carbon with a 10 M activator is 0.1499 mg/g. Keywords:PET, Adsorbent, HCl, Laundry Waste, Phosphate
