Image classification can be done by using attribute of text that come along with the image, such as file name, size, or creator. Image classification also can be done base on visual content of the image. In this research, we implement a image classification model base on image visual content. The image classification is based on decision tree method that adapt C4.5 algorithm. The decision variable used in the decision tree generation process is image visual features, i.e. color moment order-1, color moment order-2, color moment order-3, entropy, energy, contrast, and homogeneity. The result of this research is an application that can classified image base on the knowledge of the previous classification cases. Keywords: image classification, decision tree, C4.5 algorithm

This paper presents the utilization of knowledge management system for information and knowledge model development of enterprise projects. This information and knowledge management model is based on ontology semantic data model. The ontology data model is new technique for representing information and knowledge base on more semantically conception of meanings of objects, their properties, and relations between them that may arise within certain domain knowledge. The concern of the knowledge management model is to ensure that the model allows the process of creation, access, and utilization of data in a semantically manner (for querying process) and information or knowledge of enterprise projects. The experimentation shows that project ontology model has satisfied all consistent, valid, complete, and correct ontology model criteria and can be used for semantic reasoning computation. A prototype of the proposed model can access information and knowledge from the knowledge ontology model. Kata Kunci: knowledge management system, semantic data model, ontology model, semantiq query, enterprise projects

This paper proposes The Use of KPI in Group Decision Support System Model of ICT Projects Evaluation at Loca Government Agency in Indonesia. This study is a part of the attempt to improve local government performance in Indonesia, especially for Local Government Agencies (SKPD) involved in Decision Support System (SPK), which should be optimized through Information Technology. Different from the prior research, in this paper we try to describe how to determine KPI in an ICT project at local government agency and the applicable evaluation model. Generally, this paper will discuss how to make an performance indicator, so that the output of an ICT project product can result the expected outcome, benefit, and impact. Furthermore, it will be explained in regard to the Group Decision Support System (GDSS) evaluation model by considering the applicable legislation aspect, which facilitates decision makers such as: Government Institution Executives, ICT Managers Unit, Business Process Owner Unit, and Society represented by Regional House of Representative, to give assessment or evaluation upon the implementation of ICT Projects at Local Government Agency. As the research support, survey and interview have been conducted to stakeholders in decisionmaking. The proposed model is expected to be able to give ideas and solutions in evaluating ICT Projects done at local government agencies in Indonesia.

This paper uses the concept of fuzzy logics to integrate with bee systems to solve inexact model problems. As an example, in this paper the integration will be used to minimalise the congestion of transportation problems. Bee systems face many problems for decision making when seeking for the best solution, some of them: to determine the next solution components to be added to partial solution, to determine which partial solutions should be left or not, and to determine the same partial solutions without recruiting friends from the same nest. The majority of these selection models is based on the assumption that the decision makers have the ability of processing perfect information, and are always acting rationally and exactly. However, in certain conditions, information is not exact, but is still realistic.

Seleksi asisten dosen di Fakultas Teknologi Informasi Universitas Kristen Satya Wacana (FTI UKSW) dilakukan setiap awal semester. Proses seleksi tersebut mengalami beberapa kendala, antara lain mahasiswa harus datang langsung ke kantor Tata Usaha untuk melakukan pendaftaran yang ditulis di form pendaftaran. Form pendaftaran juga pernah hilang sehingga harus dilakukan pendaftaran ulang. Proses seleksi dilakukan oleh koordinator dosen matakuliah dengan mengadakan tes atau wawancara untuk mencari beberapa informasi untuk dijadikan pertimbangan dalam memilih asisten dosen. Proses seleksi memakan waktu yang lama, sehingga menyebabkan kegiatan praktikum menjadi terlambat untuk dimulai. Pada penelitian ini dibuat pemodelan Sistem Pendukung Keputusan (SPK) menggunakan metode TOPSIS dan Profile Matching berbasis teknologi Web Service untuk mengatasi masalah dalam proses pendaftaran dan seleksi asisten dosen di FTI UKSW. Hasil akhir perhitungan menggunakan metode TOPSIS dan Profile Matching ini berbentuk ranking yang dapat digunakan untuk membantu dosen koordinator matakuliah dalam menentukan calon asisten dosen yang akan diterima.

Sistem Pakar Medis Rekomendasi Penanganan berbasis aturan (SPMRP) dikembangkan sebagai alat bantu mendiagnosa gejala yang berkaitan dengan penyakit tropis yang diberikan, menunjukkan penyakit yang mungkin, dan penanganan yang mungkin didasarkan pada diagnosis. Namun pada tulisan ini, penulis memfokuskan pada salah satu penyakit tropis, yaitu tuberkulosis. SPMRP menggunakan basis pengetahuan yang terdiri dari tiga struktur pengetahuan, yaitu gejala, penyakit dan rekomendasi penanganan. Sistem SPMRP memiliki antarmuka yang user-friendly sehingga memudahkan pengguna untuk memberikan atau mendapatkan informasi ke / dari SPMRP selama run-time. Berbagai gejala penyakit tropis disimpan di pusat diagnostik dan pasien memilih tanda dan gejala dari daftar drop-down. Data-data ini kemudian digunakan oleh SPRMP untuk melakukan diagnosis dan rekomendasi penanganan. Mesin inferensi SPMRP menggunakan mekanisme forward chaining untuk mencari basis pengetahuan gejala penyakit dan rekomendasi penanganan yang terkait dan sesuai dengan data yang diberikan oleh pasien. SPMRP dibagun dengan tujuan membantu orang-orang yang tidak memiliki atau kesulitan akses ke fasilitas medis dan juga oleh mereka yang membutuhkan solusi pertolongan pertama sebelum ke konsultan medis. Selain itu, dapat digunakan untuk pembelajaran atau sosialisasi tentang penyakit truberkulosis. Dengan demikian, SPMRP akan mengurangi beban kerja dokter selama konsultasi, memmbantu pihak pemerintah dan meringankan masalah lain yang terkait dengan konsultasi penyakit tuberkulosis dan penanganannya
