Judul: Perbandingan Kinerja Algoritme TextRank dengan Algoritme LexRank pada Peringkasan Dokumen Bahasa Indonesia
Abstrak: Text summarization is an effective way to obtain information from a document without reading the whole document. Currently the small number of automatic text summarizations for Indonesian are available compared to those for other languages. This study develops an Indonesian automatic text summarization using the graph-based methods, the TextRank algorithm and the LexRank algorithm. It has been proven that the methods and the algorithms have good performance in summarizing texts for English. This work extracts about 25% of the total of sentences in the document. The kappa measure method is applied to evaluate the results of the two algorithms. The result based measure kappa on shows that the TextRank algorithm has better performance than the LexRank algorithm

Judul: Peringkas dokumen berbahasa indonesia berbasis kata benda dengan BM25
Abstrak: This research develops summarization of Indonesian documents based on nouns. The problem in this study is that high number of digital documents makes it difficult for the reader to find the desired information. We use cosine similarity, content overlap, and Okapi BM25 in the summarization. This research used newspaper articles from previous research. In the process of summarization, before calculating the similarities, the documents were preprocessed using stoplist, stemming, and selection of nouns. Then, the documents were ranked using PageRank. We used kappa measure to evaluate the level of agreement among evaluators in assessing the relevance of the summaries. Dice coefficient was used to compare automatic summarization to manual ones. Based on the observations, we find that Okapi BM25 is better than cosine similarity and content overlap.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
