<![CDATA[Masalah pencemaran kualitas air terjadi di beberapa daerah terpencil di Indonesia. Pencemaran yang terjadi umumnya bersumber pada banyaknya sedimentasi yang berasal dari wilayah hulu dengan banyaknya penebangan hutan dan pembukaan lahan pertanian secara liar oleh masyarakat. Untuk mengendalikan pencemaran yang terjadi di remote area ini, perlu dipantau menggunakan teknologi telemeteri online monitoring kualitas air. Adanya keterbatasan sumber energi listrik di remote area menyebabkan perlunya dilakukan inovasi sumber listrik menggunakan tenaga surya untuk mengoperasikan sistem peralatan telemetri. Tulisan ini membahas pengembangan sistem sampling pemantauan kualitas air yang dapat dioperasikan menggunakan sistem pompa 12VDC yang digerakkan dengan sumber listrik tenaga surya. Penelitian diasumsikan untuk memantau kualitas air sungai di remote area dengan sumber air sungai di kedalaman 8~12 meter. Sistem sampling yang dikembangkan adalah sistem bertingkat (cascade) menggunakan pompa 24VDC. Hasil penelitian menunjukkan bahwa untuk memompa air sungai dengan posisi lereng yang curam perlu dibuat sistem sampling bertingkat menggunakan pompa submersibel 24VDC. Kata kunci: pencemaran air, kualitas air, sistem pemompaan, sistem sampel, tenaga surya]]>

<![CDATA[Semayang Lake and Melintang Lake in Kutai Kartanegara district, East Kalimantan is one of the biggest lake in Indonesia. Both lakes are located in the Mahakam River Basin and has an important role for economic and ecological activities in the Province of East Kalimantan. In addition to being a source of livelihood for fishermen around the lake, is also as habitat for freshwater mammals Pesut Mahakam that are endangered. Illegal logging in the forest around the lake, causing floods when it rains and water pollution will increase with sediment flowing into the lake. In some areas also get the impact of transportation activities of coal mining industry around the Mahakam River. All this causes silting almost the entire surface of the lake, lead to a reduction of existing fishery potential and cause extinction of Pesut Mahakam. To control pollution in the lake, local government of Kutai Kartanegara has implemented an online monitoring technology to monitor the water quality of the lake in four point location. Monitoring results are used to support local goverment in taking pollution control policies in both lakes. Keywords: Water quality online monitoring system, lake water quality monitoring system, GSM and SMS technology, multiprobe sensor, telemtry system.]]>

<![CDATA[Online and realtime monitoring system for water quality that uses a computer mainboard as data logger requires software applications that serve to control the sensor work in order to measure the water quality data and sends it to the data center. Some of the requirements such as data measurement, storage and delivery of data and early warning system are required by the data logger in order to have the features as desired by the majority of users of this system. To facilitate the making of the program code, sensor with serial communication ports (RS232C) will be used. Program control data logger that meets these requirements is developed using Water Flow Software Development Life Cycle method and using GNU C++ the free open source software (FOSS) as the development tools. Program control data logger that has been developed will be installed to the data logger hardware and operated using FreeBSD as the Operating system. The program will run on the class 10 of flash drive with 16 giga byte capacity. Keywords: water quality monitoring, online/realtime monitoring, early warning system (EWS), open source software, data logger, onlimo OSS, control data logger, GNU C++]]>

<![CDATA[Environmental contamination and global climate change cause degradation of fresh water in the whole world. Increasing of oil price also insist the water treatment operational cost rise, especially for pumping and water lifting from the low land areas to up land. One of alternatif solution to reduce operational cost is using Hydraulic ram pumps (hydram pump). Hydram pump are water-lifting devices that are powered by filling water. Such pumps work by using the energy of water falling a small height to lift a small part of that amount of water to a much greater height. In this way, water from a spring or stream in a valley can be pumped to a village or irrigation scheme on the hillside. The main and unique advantage of hydram pumps is that with a continuous flow of water, a hydram pump operates automatically and continuously with no other external energy source - be it electricity or hydrocarbon fuel. It uses a renewable energy source (stream of water) mid hence ensures low running cost. Minimum up lifting vertical power of pump is twice than vertical distance of water down and maximum up lifting vertical power is twenty times than vertical distance of water down.   If there are air captured in distribution pipe, it will need release valve. In this paper, different aspect of designing a hydraulic-rain pump system is discussed. Application and limitation of hydram pump is presented. It imparts absolutely no harm to the environment Hydraulic ram pumps are simple, reliable and require minimal maintenance. All these advantages make hydram pumps suitable to rural community water supply and mud backyard irrigation in developing countries. Kata Kunci : Air bersih pedesaan, pompa hidram, pengelolaan air bersih.]]>

<![CDATA[Industrial area represents location where some industries operate in one same area region. Usually an industrial area besides there are factory also there are office and housing. To fulfill domestic clean water required by housing and office, usually the organizer of industrial area have developed a Water Treatment Plant (WTP) with source of raw water which come from a river emitting a stream of around area. The increasing of domestic clean water needs has pushed management to increase the production of clean water by the existing WTP. Besides that, to increase the quality of clean water service to the domestic exist in industrial area, hence felt important to develop a system of SCADA to manage existing process in the WTP. As step early is to identify and plan the design system of SCADA for domestic WTP. From the result of development planning, the SCADA can be developed step by step according to the project plan and existing budget. Kata kunci : Water Treatment Plant (WTP), Instalasi Pengolahan Air (IPA), Kebutuhan Air Bersih Domestik Perumahan, Supervisory Control And Data Acquisition (SCADA).]]>

<![CDATA[The need for clean water in big cities is very dependent on water supply by water companies (PDAM). The increasing demand for clean water in big cities is proportional to the increasing of number population and industry, but not comparable to the clean water supply and quality of raw water available. PDAM has made various efforts to improve the quality of clean water services to the community. One of the effort is to improve the performance of water treatment plant (WTP). To support the improvement of the performance of WTP, required water quality monitoring at the intake location in use. This paper discusses the online and realtime water quality monitoring at the water intake location using a multi-probe digital sensor and GSM technology. This observation data is used as a comparative data analysis of laboratory data on raw water source PDAM Taman Kota (Cengkareng Drain). Keywords: air baku air minum, intake PDAM Taman Kota Cengkareng Drain, pemantuan kualitas air, multi probe digital sensor, teknologi online monitoring, Water Treatment Plant]]>

<![CDATA[Fast growing development at big cities such as Jakarta usually cause surface hydrology problems, which is indicated by many surface detention and local floods during rainy season. These problems were raised because of the increasing of runoff coefficient of sub catchment areas and limited capacity of existing drainages. Analysis have made on drainage capacity of sub catchment areas connected to peak flow cause by rain on certain recurrence period and result in data to evaluate drainage capacity to solve these water detention and local floods problems. Katakunci : Genangan, Banjir, Drainase, DAS, Database.]]>
