Judul: Perbandingan Metode Knowledge Graph dan Concept Mapping sebagai Teknik Menangkap Pengetahuan., The Comparison of Knowledge Graph and Concept Mapping Methods as Knowledge Capturing Technique
Abstrak: Pengetahuan merupakan faktor yang paling penting untuk meningkatkan kualitas sumberdaya manusia. Pengetahuan dapat diperoleh dari berbagai sumber, salah satunya teks. Teks yang akan dikaji pada tulisan ini adalah teks berbahasa Inggris dengan jenis recount text dan hortatory exposition. Untuk mendapatkan pengetahuan tersebut, diperlukan suatu metode yang efektif dan efisien. Karya ilmiah ini mencoba mengimplementasikan dan membandingkan metode Knowledge Graph (KG) dan Concept Mapping (CM) untuk menangkap pengetahuan dari teks. Berdasarkan aspek proses, metode KG lebih mudah diimplementasikan dalam komputer. Di sisi lain, metode CM memiliki konsep yang bebas. Karena itu, metode ini lebih subjektif, lebih sulit diimplementasikan dalam komputer. Metode KG menghasilkan representasi pengetahuan berupa graf dengan struktur nonhierarki, sedangkan metode CM berupa diagram konsep dengan struktur hierarki. Untuk jangka panjang, metode KG dipercaya menjadi metode yang potensial untuk mengembangkan sistem abstraksi teks., Knowledge is one of most important factors for increasing human quality. Knowledge is obtained from various sources, for example from a text. In this research, we used English recount and hortatory exposition texts. For capturing the knowledge, we need an effective and efficient method. We try to implement and compare Knowledge Graph (KG) method and Concept Mapping (CM) method to capture the knowledge from a text. From process aspect, the KG method is more easily implemented automatically than that of CM method, because KG method has a limited number of concepts. On the ather hand, CM method has more free concepts, hence, it isi more subjective. Therefore, it is more difficult to implement automatically. The result og KG method is a nonhierarchy structure of graph representation, whereas the result of CM method is a hierarchy structure of concept diagram. For a long time goal, KG method is believed to be a potential method for developing a text abstraction system.

Judul: Perbandingan Knowledge Graph dan Conceptual Graph sebagai Metode Representasi Teks
Abstrak: To capture the knowledge or information of a writing, it is easier from images or graphics than it is from texts or tables. Texts are represented by Knowledge Graph (KG) and Conceptual Graph (CG) in mathematical methods. This paper compares KG and CG in representing text based on aspects of the processes, the graph structures, and the long term goals. Based on the aspects of the processes, KG is more simple and objective than CG because KG has limited relationships. Based on the graph structures, CG is more easily to be understood than KG because CG’s relationships can taken from word of the sentence. Based on the long terms, KG method is believed to be a potential method for developing automatic text abstraction systems.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
