Abstract

Natural Deduction settlement in the realm of propositional logic, normally resolvedthrough top-down techniques, which means that the deduction starts from an expressionthat has been given and or with the assumption, then the rules of certain inferenproduce the next process is called derivation. This method done continuously until thelogical expression to be proved as the results are really materialized.Top-downapproach has certain difficulties not easily solved the difficulty to find an expressionthat became the beginning of proof or of the assumptions used. The difficulty isattempted facilitated by the completion of proof is reversed by bottom-up techniques.Verification process should start from the proved to find beginning of the proof.Toexplain the process of bottom-up approach, in this paper will be given an example onone of the Natural Deduction proof by Gentzen system.

Abstract

Jakarta is Indonesian’s capital city which is the central of the most activity andeconomical activity for the people from all around Indonesia. The High mobility ofroad user is one of the things that become a problem in Jakarta. A road is a primaryaspect for a good traffic. The road itself is depend on how good or how bad thecondition itself, such as the construction, aging and a weight of the vehicle and There isa possibility of the quality of road is going to change depend on the situation.A road mapping is needed to deciding, planning and to caring the road by thegovernment to build a good traffic of people’s transportation. That is why, the localroad mapping is very important. The present writer is making a Sistem InformasiGeografis (Geographic informational system-SIG) which is talking about local roadmapping and a second collector which is using an OpenGeo Suite with the support fromframework OpenLayers. OpenGeo Suite is used for mapping digitalization process.PostgreSQL 8.2.4. Is used as a data base and Adobe Dreamweaver CS 3 is used to editthe PHP coding system. The mapping system from the layer is contains of roaddimension, technique of the road, road location, road condition and road user. By theSIG local road mapping site and second collector, people is be able to know about theroad mapping easily and it also be able to be the key for a planning and caring of theroad in the south Jakarta.

Abstract

Dalam beberapa kasus, data gambar memerlukan pengamanan agar tidak dapatdibuka dan dilihat oleh pihak yang tidak berkepentingan misalnya gambarperencanaan denah sebuah proyek perumahan pada perusahaan kontraktor yangmenjadi rahasia perusahaan. Solusi dari permasalahan ini adalah menggunakankriptografi. Salah satu metode kriptografi adalah Metode Government Standart(GOST), dimana Metode GOST merupakan suatu algoritma enkripsi sederhana yangmemiliki jumlah proses sebanyak 32 round (putaran) dan menggunakan 64 bit blockcipher dengan 256 bit key. Metode GOST juga menggunakan 8 buah S-Box yangberbeda-beda dan operasi XOR serta Left Circular Shift. Pembuatan Sistem EnkripsiGambar dengan metode GOST adalah dengan menyeleksi warna RGB (Red, Green,Blue) pada gambar dan dirubah ke bilangan heksadesimal, lalu di enkrip menggunakanMetode GOST. Hasil dari sistem ini adalah dapat mengenkrip sebuah gambar yangutuh menjadi seperti sebuah gambar yang tidak mempunyai arti (gambar terenkrip),sehingga kerahasiaan gambar tersebut tetap terjaga.

Abstract

Convex optimization is one of important areas in nonlinear programming, both fromthe mathematical and application viewpoints. Numerous real world problems arenaturally expressed as quadratic programming problems. In non linear programming,it is necessary to use a method to get global optimal value in order to not get trapped inlocal optimal value. Branch and bound method in non linear programming known asone of global optimization technique.In this research we implement branch and boundmethod with relaxation process in the problem to get global optimization from convexprogramming. The boundary of sub problem will be considering using reformulationfrom quadratic with KKT condition. Experiment was accomplished on quadra1ticprogramming problems. The results showed that using reformulation from quadraticwith Karush-Kuhn-Tucker (KKT) condition for bounding the problems helps to getoptimal solution in branch and bound method.
