Abstract

Indonesia is a country that most people farming his work as a farmer, but on the other hand that there is land in urban areas is already diminishing because a lot of the construction of buildings, malls, factories and as her even more public demand for vegetables from year to year has increased drastically and the solution to this problem is with a hydroponic system.Hydroponics is growing plants and growing techniques that utilize water instead of soil by emphasizing the need nutrients,temperature and pH for plants. Needs of hydroponic water at less than the plant with soil media, so is suitable for areas that have water supply and limited land. (https://id.wikipedia.org/wiki/Hidroponik) History Hydroponic growth in 1963 was born a term Hydroponics, a term given by someoneagronomy from the University of California, United States. beginning of activities to cultivate plants without soil media. Beginning of hydroponics experiment originated from research work in plant physiology laboratory testing using water fished. These systems use a lot of water as a growing medium that many people regard these media as aquaculture (Farming in the water). In the historical record how hydroponics has been around since thousands of years ago, for example, described in Babylon existing hydroponic hanging plants and floating plants in the region of china.In 1980,Indonesia began to develop hydroponics.

Abstract

An artificial neural network is a representation of the 'artificial' of the human brain is always trying to simulate the learning process of the human brain. As nerves are the cells that process information in the brain and form a network as a whole. The term 'artificial' used in neural networks implemented using a computer program that is able to resolve a number of the calculation process during the learning process. An artificial neural network model a structure similar to the human brain. An artificial neural network has been used for image pattern recognition, character, and sound that is always trying to simulate the learning process of the human brain, one it is in the process of character recognition. How it works is an input image is converted to form a 10 x 10 matrix is then stored in a knowledge base file. The patterns saved earlier will be used as a pattern to be referenced at the time of the test pattern on the computer. The test is performed by comparing the test pattern with the pattern that has been stored on a computer by using ANN. Optical Character Recognition (OCR) is an application in pattern recognition to recognize the characters in digital images. OCR applications are already found in smartphones, especiallythe use of Android. Besides adequate hardware specifications for digital image processing, development of open-source library for image processing on the Android facilitate the development of software.

Abstract

Today the level of falsification of signatures is very common. Perpetrators are often categorized based on the quality of the crime, and the motive of his actions. In falsifying signatures actors also have special characteristics that make it distinguishable from each other. Perpetrators forged the signatures of his actions as 'fine' so unknowingly carry have become victims of crime. The signature is one that is widely used biometric humans. Signature also special of handwritten forms that contain special characters and additional forms are often used as proof of identity verification of a person. In the process of identifying the signatures still done scientifically by matching signatures, but how did the introduction of a signature using a computer viding a challenge until now, because the form of a signature unique to each person. Differences signature manually can be seen from the hassle pattern used by the owner. Some sample signature of each person are generally identical, but not really thesame. Signature of person often change over time, usually in terms of position and size of the signature. Usually a signature is used as the primary mechanism to authenticate and authorize the transaction legal. And can also be used to identify one person to another. Based on the description above, this research is expected to help in reducing the crime rate in the use of signatures.

Abstract

According to the meaning literally, the image (image )is a two-dimensional image on the field. Judging from the mathematical point of view, the image is a continuous function (continue) the intensity of light in the two-dimensional plane. The light source illuminates an object, then the object reflects back a portion of the light beam. This light reflection is captured by optical devices, such as the human eye, a camera, scanner, and others so that the shadow of the object in the form of the image can be recorded (Sitorus, Syahriol, 2006). In scientific writing, the author analyzes on the detection of handwriting on a blackboard. Handwriting recognition is one area of pattern recognition and is a part of computer sciencefield Computervision and artificial intelligenceis being developed at this time.While the blackboard were planks of wood with a surface that can be rewritten by using markers. Chalkboard ancient times was made of a thin sheet of slate black or gray. Chalkboard is now made of sheets of thin boards painted with glossy paint, usually white. Whiteboards are commonly used in schools and educational institutions. With a variation of a wide variety of reasons. Chalkboard often unpopular student with written reasons lecturer on the board can not read, so difficult to understand.

Abstract

Indonesia is one country that has greatest.Sea waters is an ecosystem rich with natural resources that can be utilized for prosperity and well-being person.As it is known that 70% of the earth's surface covered olehwaters / sea and more than 90% of the biomass of life on the planet live in the sea. There for the ocean is an important part of human survival. (Sudrajad, 2006). Most of the territory of the Republic of Indonesia consists of ocean waters is located very strategically. Indonesian marine waters other than utilized as local and international communications facilities, also has a very rich marinere sources and other resources important among fisheries, coral reefs, mangroves, minerals, and its coastal area can be used as a tourist attraction which is underwater has interesting.Robot became one of the effective means to support human beings in terms of underwater exploration. Because humans have limitations to be able to withstand the pressure underwater so great. Underwater robots have become one of the effective means to replace humans in exploring underwater. Exploration in this case has a broad meaning, ranging from the simple exploration of the underwater ecosystem sort ofobservation, to discover such high risk seabed sampling to detect metal mine at a depth of more than 1000m. Such exploration can still be done without the need for direct human intervention in exploring.By using underwater robots, humans are just waiting on the mainland for the next task is done by venturing underwater robot.
