This paper presents a decision model for technical solution options on building system selection. There are many studies on design decision making using multicriteria, such as in assessment of exterior building wall system; selection of steel structure; structural alternatives of prefabricated concrete and metal clad; and roof system selection. The characteristic of value criteria has not been widely used to previous research. Existing models that are commonly accepted are optimization-based models, for example aggregation methods, but these are not able to solve the problem of value criteria on design decision. The model is based on a satisficing function/cost preferences. It is multi-attribute, and the environment is in a Value Management (VM) process. Since “value” is the main single objectives for the decision model of VM, the attributes for this decision model therefore is function and cost. This also provides the method to construct the Life Cycle Cost (LCC) analysis for the cost attributes and the Function Analysis System Technique (FAST) for the function attributes. This research applies the satisficing game method where function and cost of solution techniques for a building system is formulated and the reduction of the technical solutions based on function/cost preferences can be made. Therefore solving the problem on computerizing the creativity of human/decision participant helps to elaborate on every possibility of the technical solutions and reduce them before choosing the best solution

hydroponic cultivation technique has been widely used by farmers in Indonesia, especially for growing vegetables. Cultivation of plants hydroponically has several advantages such as: (1) does not require a large area and treatment more practical and thus require less labor, (2) to use fertilizers more efficiently, (3) the plant grow more rapidly and success is assured, (4) planting can be done continuously without depending on the season, (5) can be scheduled so that harvesting can produce crops continuously, and (6) the selling price is more expensive hydroponic vegetables (Lingga, 2005). Hydroponics is the cultivation of plants using water as raw material to support the growth of these plants. For a plant good growth hence the need for adequate nutrition needs. The nutrients can be mixed into the water so that the spread of nutrients to be evenly distributed and easily for dissolved. In addition to nutritional factors that can affect the growth of the well can also be affected by the EC (Electro Conductifity), pH, and temperature environment. All three of these factors can be detected by the sensor, the sensor is controlled by a microcontroller Arduino Uno. Microcontroller function to input signals from the sensors enter the EC, pH, and temperature and then the microcontroller to process the input to generate output results. In the hydroponic system has a model in the planting system that is one which will focus on the study authors used a model NFT (Nutrient Film Technique). NFT (Nutrient Film Technique) is a model of hydroponic cultivation with plant roots lay in a shallow layer of water. To be circulated water and nutrients needed by plants. Rooting can thrive in the nutrient solution. Because there rooting around the layer of nutrient solution, then the system is known by the name of the movie nutrient technique (NFT) (Lingga, 2011). Planting hydroponics has aspects that must be considered such as the type of plant, ambient temperature, ph, nutrients that are suitable for use and EC (Electro Conductifity)these aspects should be in accordance with the plant whatever, which is suitable to be planted simultaneously when viewed from the EC, pH, temperature , Hence the need for recommendation systems

As maritime state, most of Indonesian reside in coastal areas or estuaries, leading sanitation and water supply a major concern of the people. The use of groundwater with considerably limited amount is more limited due to seawater intrusions. On the other side, surplus of freshwater from upstream is very abundant near the estuaries. However, morphological condition of river downstream or in estuaries with huge dimension and depth causes expensive cost in order to utilize freshwater in estuaries. One of the solutions to utilize water downstream or near estuaries as raw water for clean water is to build free intakes around river estuaries. However, as the utilizing proceeding, it is found a problem that intake capacity is far below their design capacity. The research is an experimental research conducted in the laboratory which aimed to investigate the relationship of flow velocity distribution on no free intake and with free intake condition and its influence to the capacity of free intake structures. The result shows that either on no free intake and with free intake condition minimum velocity occurs around channel bed and increasing upright and decreasing again when approaching surface of the channel. The positioning of intake pipe is highly influencing intake capacity. Maximum condition is achieved when intake pipe is positioned on channel bed and near channel surface while minimum condition is achieved when pipe is around middle part of the channel. Keywords—Free intake: velocity distribution: intake capacity.

In some circumstances, sometimes people are faced with several options. Such as selecting school, choose a subject, choose a place of residence, employment and others. Determining the choice was not easy, making indecisive and difficult to take decisions. And sometimes people pay less attention to the positive and negative impacts in making a decision, as well as the lack of attention to aspects or essential criteria required. Moreover, if the wrong decision, can be bad for the man himself. Therefore, it is necessary Decision Support Systems. Decision Support System (DSS) or Decision Support System (DSS) is a system that can provide problem-solving ability and the ability of communicating to a problem with the condition of semi-structured and unstructured. This system is used to assist decision-making in situations of semi-structured and unstructured situations, where no one knows for sure how the decision should be made (Turban, 2001). The method used by the author in the Decision Support System is a method Technique for Order Preference by Similarity to Ideal Solution (TOPSIS)
