<p align="justify">PT. YMI is one of the automotive manufacturers for two-wheeled vehicles. As a part of the Astra Group, the company strives to become a "Green Company" through the AGC (Astra Green Company) program. One of its assessments is a 30% wastewater recycle program per month which aims to save or use clean water efficiently. The technology used for purification of effluent water from waste water treatment is by Reverse Osmosis technology with initial treatment by using Cation Resin, Activated Carbon and Micro-filtration process. The membrane used for this Reverse Osmosis system is the Filmtec 30-4040 TW / BW. The result of the application of Reverse Osmosis technology to clean water usage in PT. YMI is 34.99% which this success can be achieved due to the recycling of effluent water contributing 100%. In addition, there are also benefits obtained from the absence of effluent water into the industrial estate. Income fee earned amounted to Rp 23,591,675, - / month. For expenses (electricity usage, spare part and overtime) Rp 11.470.172, - / month so the profit earned is Rp 12.121.503, - / month. Payback Period for this R.O. system will be achieved for 24 months or 2 years.</p>

Abstract—Water is an important element that becomes the need of every human being, in the service provider company Clean water control of water usage is still a problem because there is no system that provides information on the use of water on the customer side, especially in the BLUD UPT SPAM Musi Rawas. Customers also find it difficult to see the amount of bills in realtime so that if the billing information has been presented then the customer can adjust the use of the water. This system will use a Waterflow Sensor to read the water flow which will then be converted to Digital data in the form of computer bits that will be processed by Arduino and then sent to the Server to be seen by the Clean Water Service Provider in this case the BLUD UPT SPAM Musi Rawas and customers. Intisari—Air merupakan unsur penting yang menjadi kebutuhan setiap manusia, pada perusahaan penyedia layanan Air bersih kontrol penggunaan air masih menjadi masalah karena belum ada sistem yang menyediakan informasi penggunaan Air pada sisi Pelanggan khususnya di BLUD UPT SPAM Kabupaten Musi Rawas. Pelanggan juga kesulitan untuk melihat jumlah tagihan secara realtime sehingga jika informasi tagihan tersebut sudah tersaji maka pelanggan dapat mengatur penggunaan Airnya. Sistem ini akan menggunakan Waterflow Sensor untuk membaca aliran air yang kemudian akan di konversikan ke data Digital  berupa bit komputer yang akan di proses oleh Arduino kemudian di kirimkan ke Server untuk dapat di lihat oleh Penyedia Jasa Air bersih dalam Hal ini BLUD UPT SPAM Kabupaten Musi Rawas dan Pelanggan.

Two important applications of membrane processing in the metal-finishing field are the use of reverse osmosis for electroplating waste treatment, and ultrafiltration for concentration of oily wastes prior to disposal. Waste waters from electroplating contain contaminants of high toxicity, but also of substantial potential value. Reverse osmosis has been used to close the loop on treatment of individual plating bath rinse waters, returning concentrates to the baths, and reusing purified water for rinsing. A discussion of advantages and limitations is presented for treatment of various plating baths. Reverse osmosis has also been used to concentrate electroplating shop mixed effluents, with up to 95 percent water recovery for reuse. The low-volume concentrate is dried for ultimate solids removal, and waste-water treatment becomes closed loop. Data are presented for this application. Spent oil-containing coolants present the metal-finishing industry with a difficult waste-treatment problem. Conventional disposal of the 1–5 percent emulsions by chemical destruction, incineration or contract hauling is expensive. Ultrafiltration has been employed to concentrate emulsions to over 50 percent oil. These are readily incinerated with no fuel addition required, and work has been done which shows that reuse of the oil either upgraded to a fuel or a lubricant is the best answer for the concentrate. Data are presented for concentration of several wastes.

Reverse Osmosis Membranes

Water pollution comprises all of those compounds that change the quality of groundwater and surface water, therefore reducing the suitability of natural water for human use and other vital processes. These compounds result from human activities, especially those that are industrial, agricultural and domestic.The polyamide thin film composite reverse osmosis membranes become important in desalination of sea water and brackish water or waste water. However the polyamide reverse osmosis membranes tend to fouling due to their hydrophobic and rough surfaces. In this study flux and rejection of waste water from aluminum production industry were obtained during filtration process by using modified commercial composite membranes. Amount of fouling was evaluated with unmodified and modified membranes. Rejection of iron particles and PH of feed and permeate solutions were determined after filtration process. Results shows that modified membranes were performed higher metal ion rejection and antifouling performance than unmodified membranes.

<p class="Summary">Adoption of new technologies is a process that involves technological learning and penetration of new products into the market. Within the process of new technologies adoption, government usually intervened by providing incentives, in order to support the technology adoption to be succeed. This paper examines the effectiveness of incentives for the sustainability of reverse osmosis (RO) membrane technology adoption. The study conducted through single case study on SWRO installation in Mandangin Island, East Java, Indonesia. Results of case study indentify the existence of government incentive in the form of direct subsidies to decrease the price of clean water. Although successful in reducing the price of water, but effectiveness of the subsidy on the sustainability of SWRO is still low, which is operates only 30% in a year. Further analysis shows that these subsidies actually be counter-productive to the sustainability of SWRO installation.</p>

Increasing population and household growth cause the need for housing to shift to urban areas and develop into multi-story housing such as condominiums, apartments and so on as a result of urbanization. Pasir Putih View Condominium Hotel - Situbondo (Condotel) is one of the real indicators of the economic, social and cultural progress of the people in a region. The construction of the Condominium Hotel (Condotel) project requires careful planning in terms of structure, architecture, and also mechanical electrical plumbing. Building planning, especially on mechanical electrical plumbing (MEP) must be adjusted to the number of guests or people who are in the condotel area. One of them is planning the Waste Water Treatment Plant (WWTP) which will be recycled and used for one of the condotel requirements. This WWTP plan starts with determining the total clean water requirements and the total flushing needs needed. The method of data analysis is done by calculating the total water discharge planning needed and the results from the dimensions of the WWTP space needed. The results obtained are in the form of the calculated discharge volume and WWTP space data which is accompanied by shop drawing images in which a comparison of the old design with the new WWTP design. The discharge volume of the total clean water requirement obtained from the calculation is 179.04 m3. The calculation for the dimensions of the WWTP space needed is 13.5mx5mx4m. From the type of WWTP, the time to treat wastewater into environmentally-friendly (non-consumption) water can be 50% faster. WWTP type planning is done to produce more efficient planning of the WWTP that had been planned by the previous consultant while not ignoring security factors
