Basically, nature has the ability to perform the restoration of environmental damage caused by increased human activity, but because of the limited carrying capacity, then the environment has decreased the quality from year to year. In saving the environment, technology plays a role in reducing the risk of pollution, increased efi siensi process, and creating processes and environmentall friendly products, monitoring and prediction of environment quality, environmental pollution control, restoration and environmental improvement. Waste Technology (end of pipe technology) are widely used to cope with environmental pollution, both for liquid waste, solid and air. Waste processing technology developed for the waste can be in accordance with quality standards thathave been established, while monitoring technology has been developed either manually or automatically. For recovery and improvement of technology has been developed remedies and restoration that rely on bacteria in nature.Keywords: end of pipe technology, reuse, recycle, reduce (3R), carrying capacity, and environment pollution

Blue crab canning is a high protein, low fat, and multi functional product. Waste that produced from blue crab canning needs handling and processing that couldn’t make a negative impact to the enviroment. The study on waste management, is a very important for student because they can learn about how to make a canned blue crab directly from the factory, get to know about the waste implementation and also get to know about the problem that caused from the waste implementation management at PT. Sumber Mina Bahari Rembang, Central Java. The purpose from this activity is to get to know the implementation of waste mangement from blue crab canning ( Portunus pelagicus )PT. Sumber Mina Bahari Rembang, Central Java. According to Saptadewi (2013), the waste that produced from blue crab canning are solid waste and liquid waste. The solid waste are like blue crab shell, broken cans, and sand. Meanwhile the liquid waste are like the leftover water from production, sanitary needs, and boiling processing. The study have been done on January 23rd  2017 until  February 21st 2017. This activity was held at at PT. Sumber Mina Bahari Rembang - TubanHighway 31st KM, Sumber Sari Village, Kragan Disctrict, Rembang Regency, Central Java. The waste that produced by PT. Sumber Mina Bahari are separeted in two types that liquid waste and solid waste. The waste has been processed quite well, it has been proven with a cooperative contract between PT. Sumber Mina Bahari with the Rembang City sanitary agency at a solid waste processing. The liquid waste certification shown that PT. Sumber Mina Bahari is very keeping the enviroment clean meanwhile the management functions like planning, organizing, actuating, controlling, and evaluating didn’t mention very well. It is happen because there is no special division in waste processing in between PT. Sumber Mina Bahari.

Low Level Radioactive Waste

Within the management of radioactive waste, we sought to consider a new approach radioactive hazardous waste processing in aqueous or similar (low-level waste; LLW) forms LLW and in fact, ‘contaminants of concern’ is often stored as diluted aqueous solutions of radioactive (or non) elements and contained in storage containers. One of the general problems associated with mixed liquid waste is the lack of an efficient, effective, and inexpensive means of processing (separating) its constituents. Two of the objectives in processing solid, radioactive laden liquid LLW are as follows: 1) to separate/extract the radioisotopes from the rest of the mixed constituents, and 2) to produce stable solidified forms encapsulating radioactive elements. Recent R&D in the physical chemistry of gel materials, have identified promising approach to simultaneously achieve the above objectives. That is, by utilizing and manipulating the physicochemical properties of various silica- and polymer-based gels at the nanoscale, we have demonstrated a process by which to specific chemical species are encapsulated.

Reliability And Availability

Abstract Remotely operated and unmanned facilities offer significant safety, environmental and economic benefits over conventional facilities. This paper describes the key elements for successful design and an approach for evaluating the reliability, availability and TOTEX of unmanned facilities. The approach was developed during the concept and FEED phases of a wellhead platform project and forms the basis of the unmanned strategy going forwards but can also be used for facilities with partial processing topsides. During the design of a recent platform it became clear that normal FMEA/RAM analysis was not suitable for assessing the reliability and availability of unmanned facilities with low visit frequency. Drawing on previous experience, a new approach was developed to address the specific challenges of low maintenance intervals and provide a methodical approach to proving reliability. The new approach improved confidence in the predicted availability by identifying key components and appropriate reliability data. The process adds some extra steps to typical reliability and availability assessment, which are designed to address the specific demands of unmanned operations. The result of this work has given a clearer understanding of how reliability can be assessed and managed for low-manned or unmanned applications. The methodology helps to identify unmanned /low manned opportunities and provides guidance on design and reliability assessment It is observed that system reliability is usually driven by a few key components and that whilst many components have good overall reliability data this may not be applicable for the proposed specific operating environment and maintenance regime of an unmanned platform. It is therefore essential to evaluate components individually for their specific applications. It is concluded that to achieve the unmanned goal it is vital to fully understand the system and component reliability early in the project. The proposed methodology can be applied at any stage to validate the design, confirm assumptions, or identify gaps.

With the introduction of third generation of nuclear power AP1000, Westinghouse uses the mobile device (a mobile wastewater treatment device 6 units shared) radioactive waste system design concepts. This design not only simplifies the process of nuclear island waste system; saves equipment layout space; improves equipment utilization; while increases the use of new technologies lifetime of the plant and the possibility of flexibility. This paper introduces the first AP1000 unit (Sanmen, Zhejiang Province) by using the advanced mobile device technology and application of wastewater treatment under the condition of the primary coolant source level. At the same time, the paper also discusses the periodic system inspection and the strategy of maintenance. In addition, the paper further expands the application direction of the mobile waste processing aspects, such as: decommissioning of nuclear facilities; enhancing the facility decommissioning radioactive liquid waste purification capability. Another example: After the Fukushima accident, people pay more attention to accident-mitigation-design and hope to accelerate the development of emergency radioactive liquid waste processing devices. Thus, in addition to strengthening the nuclear power plant inherent defense in depth and resistance emergency capability, mobile waste treatment device or combination device special regional settings can be made to improve and enhance the ability to get more diversified emergency response.
