The environment of the rivers surround Jakarta was polluted due to the increasing of the domestics and industrial waste as response to the rapid development of the anthropogenic activities within the city since the decades. As consequence, the carrying capacity of the water ecosystem was degraded including Jakarta Bay as the estuary of the passing rivers of the Jakarta City. This article briefly discusses the pollution problem within the Jakarta Bay that is supported by the data collected from various sources including the result from in-situ survey. The result has shown the fact of what the causing factors that stimulated the pollution problem within this area.  Katakunci : Pencemaran Lingkungan Perairan. Teluk Jakarta, Pantai Utara Jakarta, Air Limbah Domestik, Beban Pencemaran.

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.

Danau Toba merupakan danau terbesar di Indonesia yang memiliki peran penting sebagai sumberdaya untuk mendukung potensi ekologis dan ekonomis masyarakat setempat. Akan tetapi, tekanan pencemaran yang diakibatkan oleh aktivitas masyarakat di sekitar danau terus bertambah. Penelitian ini memanfaatkan teknologi ONLIMO yang dikembangkan oleh Pusat Teknologi Lingkungan, Badan Pengkajian dan Penerapan Teknologi untuk meningkatkan kegiatan pemantauan kualitas air di Danau Toba. Penelitian ini bertujuan untuk monitoring kualitas air di Danau Toba dengan menggunakan sistem ONLIMO yang memanfaatkan teknologi telemetri dalam pengaplikasiannya. Data diambil pada bulan Desember 2017, di 2 lokasi stasiun pemantauan yaitu stasiun 1 (STO11 di Toba Marom) dan stasiun 2 (STO12 di Toba Ajibata). Sensor yang digunakan berupa multiprobe sensor yang terdiri dari sensor suhu, DHL, TDS, kekeruhan, pH, DO, Nitrat dan Amonia. Data berasal dari database ONLIMO dan dianalisis dengan menggunakan metode storet. Hasil menunjukkan bahwa di kedua stasiun secara umum tergolong ke dalam perairan yang tercemar ringan, dengan parameter yang berada di atas baku mutu terdiri dari DO, kekeruhan, dan amonia. Penggunaan sistem teknologi ONLIMO dapat mempermudah kegiatan monitoring kualitas air di Danau Toba secara kontinyu.

Since the Internet was introduced virtual network, the globalization of information gradually changes. One positive result of the globalization of this information is the geographical boundaries are not visible in the face of the earth. Information wide open to anyone who would like to access and contribute in it. To protect the rights and obligations of both the information providers and the users from the cyber crime, the government has prepared several law and legislation. On this paper, the regulation of public information opennes (Law Number 14/2008) will be discussed, which protect the rights of people to access information held by public agencies and institutions. Example given is associated with the provision of information for environmental problems, particularly water management technology and liquid waste that has been managed by the Center for Environmental Technology, Agency for the Assessment and Application of Technology. Keywords : Keterbukaan Informasi Publik, Pelayanan Informasi Teknologi, Hak Akses, Jaringan Global Internet, Hubungan Masyarakat, Cyber Crime, dan Good Gevernance

Clean water needs and wastewater treatment will be a serious problem for industry especially for food industries. The packet information of applicable technology for water treatment and industrial waste handling that can support any development sector nowadays is needed by any kind of society especially for small and medium enterprise players. To face on globalisation, the computer and information technology will be used as an important tools for distributing the packet of technology from RD community to any kind of society through global network. By using the existing network infrastructure in the country, the packet information of technology will be distributed electronically specially to help group of small and medium industry. As pilot project, this activity chooses the tahu/tempe industry located in Semanan,JakartaBarat for the industrial centre. By surveying the need of technology, we try to help craftsman to resolve their problem on clean water supply and industrial waste, so they can increase their product quality. Katakunci: air bersih, limbah cair, sistem informasi, internet, hypertext, multimedia
