Judul: Penerapan Crawler pada Sistem Informasi Bisnis di Indonesia
Abstrak: Crawler is one of techniques to collect data from one or some websites on Internet. This research tried to use a crawler technique to get business data from two websites of business information system in Indonesia,Yellow Pages and Street Directory. The results obtained from Yellow Pages is 487.109 web pages with 4.169 category pages and 482.940 business profile pages, and Street Directory is 8.712 business locations. After data cleaning, merge of two webites are found 266.519 business data. The collected data are grouped by type and region. Region starting from provinces, city/districts, subdistricts, and villages. Business types consist of forms, fields, and categories of business.

Judul: Evaluasi Algoritme Breadth First, Best First, Dan Page Rank Pada Web Crawler
Abstrak: Web crawling is a process by which we gather pages from the web, in order to index them and support a search engine. The objective of crawling is to quickly and efficiently gather as many useful web pages as possible, together with the link structure that interconnects them. The objective of this research is to evaluate Breadth First, Breadth First with Time Constraint, Best First and Page Rank algorithms. The process of collecting web pages consists of the initialization process (keywords and starting URL), inserting a link to the frontier, stoping crawling, take\ing the link from frontier, fetch, parsing and indexing. The focus of web crawler algorithm is determines the next link that will be visited. Based on the precision and opportunity of keywords per algorithm, the result of the evaluation indicates that the page rank algorithm is better than three other algorithms. While based on the complexity of algorithm, the result of the evaluation indicates that the page rank algorithm has higher complexity as compared to three other algorithms. In addition, based on the average fetch time, the result of the evaluation indicates that the best first algorithm is more stable than three other algorithms. Keywords : web crawler, web crawling, breadth first, breadth first with time constraint, best first, page rank, cosine similarity, web crawler evalution, precision values of web crawler, complexity algorithm of web crawler.

Judul: Analysis of Increasing Plasma Temperature for D-T  Fusion Reactions in Tokamaks with Ohmic Heating
Abstrak: Reaksi fusi terkendali atau termonuklir terkendali merupakan reaksi penggabungan dua inti atom ringan menjadi inti atom yang lebih berat dengan melepaskan energi. Reaktor fusi hingga saat ini masih dalam pengembangan demi terwujudnya pembangkit listrik tenaga nuklir berbasis reaksi fusi. Biaya kontruksi menjadi salah satu faktor penghambat perkembangan reaktor fusi dunia. Penelitian ini bertujuan untuk menghitung suhu yang dapat dicapai plasma yang dipanaskan secara ohmik dalam reaktor fusi bernama Tokamak dengan ukuran radius yang divariasikan. Ukuran radius mayor yang digunakan dalam perhitungan dengan rentang 2 m sampai 4 m serta radius minor 1 m sampai 3 m. Nilai tersebut ditetapkan lebih kecil dari Tokamak yang pernah ada demi terwujudnya penekanan pada biaya konstruksi. Ukuran radius mayor memiliki peranan dalam jumlah tumbukan partikel terjadi sehingga berbanding lurus dengan suhu yang dicapai plasma. Ukuran radius minor memiliki peranan dalam proses konversi panas melalui dinding reaktor sehingga hubungannya berbanding terbalik dengan suhu yang dicapai plasma., Fusion control or controlled thermonuclear is a reaction that combines two light atomic nuclei into a heavier atomic nucleus by releasing energy. Fusion reactors are currently still being developed to realize nuclear power plants based on fusion reactions. Construction costs are one of the factors inhibiting the development of world fusion reactors. This research aims to calculate the temperature that can be reached by ohmically heated plasma in a fusion reactor called Tokamak with varying radius sizes. The size of the major radius used in the calculation ranges from 2 m to 4 m and the minor radius from 1 m to 3 m. This value is set to be smaller than existing Tokamaks in order to reduce construction costs. The size of the major radius plays a role in the number of particle collisions that occur so that it is directly proportional to the temperature reached by the plasma. The size of the minor radius plays a role in the heat conversion process through the reactor walls so that the relationship is inversely proportional to the temperature reached by the plasma.
