Abstract

Application of technology for the benefit of society by utilizing matahahari rays, where it ispossible use in locations that do not allow use of other alternative energy sources. Sunlight cangenerate electricity with solar cell power plant applications, this energy is almost never missing aday at certain locations with enough intensity radiation to produce electrical energy. Althoughcurrently still requires relatively high costs for solar cells, but by considering the factors easymaintenance and does not require routine maintenance every day, the charger circuit componentsreadily available in the market, may be set with the charging rate varies.In this scheme by considering the design of circuits that are sensitive to the setting conditionsof charging batteries in the charging condition or already full, with utilization of the op-amp as acomparator and SCR components as a component of the charging rate of electric energy to the solarbatteries, besides that also use power transistors as switches electronically at the time of chargingand at the electric charge on the batteries is full.The result of design equipment design charger with practical design with a very low cost, setthe charging rate can vary up to 10 Amperes and components are also easily available in the market.Tools charger allows for use on other plants originating from, for example, diesel generators,hydroelectric power, wind power, generating electricity from ocean waves, and so forth.

Abstract

Bamboo construction is widely used by Indonesian people, especially in rural areas, to buildinghouses, bridges, fences, etc., because it is cheap and quick to grow (bamboo can be harvested at theage of 3-5 years, compared with wood 30-50 yrs.). So much bamboo growing in the yard behind thehouse and in the field as a backup. Today’s technology can process the bamboo into bamboo laminate,so that could be used for floors, skateboard, furniture furniture until frame (frame) bike sport.Bamboo has the mechanical properties, particularly in the direction of fibers, which are quitegood. For the construction of bamboo has a weakness in the joint system. At the time of construction,connection systems rely solely on the strength of friction from the rope. Lately, research on bambooswitching system design is very diverse, but very little literature that reveal the mechanical properties(tensile strength, bending, shear, fracture and dynamic) bamboo joint system, thus avoiding thearchitects design, construction using bamboo.This study is the beginning, of a series of research on bamboo and bamboo test connection forthe dynamic character for construction. This initial research to produce a model of dynamic loadtesting tools for the construction of bamboo, for a maximum load of 5 kg, for further necessaryresearch for the design of advanced test equipment dynamic load 5000 kg and a test of the dynamiccharacter of the bamboo joint, resulting in a dynamic test data connections bamboo, thus the designerhas refrensi about the mechanical properties of bamboo and bamboo connections, which in turn canuse the software as a CAD-CAE design tool bamboo construction.

Abstract

o simplify the planning process needs reinforcement in reinforced concrete structures in simplehouses, which meet the requirements of security and comfort, requires the calculation process byusing a formula that is long enough that perhaps could only be understood by an engineer in thefield of Civil Engineering. In this subprogram II will be built a Dimension Beam OptimizationProgram Child and Parent Beams in Neutron Numerical approach Moment Style, Style and StyleNormal latitude necessary to determine the need for reinforcement beams. By simply entering someform of data input length of the beam on the program this application will get installed on thereinforcement requirements for reinforced concrete structures along with their material needs onthe job for the House Story Concrete Simple. Thus it is possible people will be able to calculateawampun needs reinforcement and concrete materials that are required on the job simple storyhouse.
