Abstract: Information extraction is an early stage of a process of textual data analysis. Information extraction is required to get information from textual data that can be used for process analysis, such as classification and categorization. A textual data is strongly influenced by the language. Arabic is gaining a significant attention in many studies because Arabic language is very different from others, and in contrast to other languages, tools and research on the Arabic language is still lacking. The information extracted using the knowledge dictionary is a concept of expression. A knowledgedictionary is usually constructed manually by an expert and this would take a long time and is specific to a problem only. This paper proposed a method for automatically building a knowledge dictionary. Dictionary knowledge is formed by classifying sentences having the same concept, assuming that they will have a high similarity value. The concept that has been extracted can be used as features for subsequent computational process such as classification or categorization. Dataset used in this paper was the Arabic text dataset. Extraction result was tested by using a decision tree classification engine and the highest precision value obtained was 71.0% while the highest recall value was 75.0%.

Abstract: Land subsidence has severe physical and economic implications for both areas and people. Numerous scholars have shown that land subsidence has had massive impacts at global, national and regional levels, and that the impacts were usually responded to by the government. However, little attention has been paid to what land subsidence means to people’s daily lives and how much it costs them. To fill that gap, this article draws on empirical research carried out in three areas in Indonesia to provide a better understanding of what land subsidence means to households, and how they respond to the consequences and how much it costs them to do so. An analysis of a survey of 330 households shows that they have been suffering from various severities of impacts of land subsidence for an extended period. Whereas some of the households respond to the impacts by making small preparations or adapting to the damages, others can do nothing due to a lack of money and their continuously declining earning capacity. Thus, the affected households are effectively throwing money into a bottomless pit. We argue that these households must escape the vicious circle caused by land subsidence by increasing their income capacity or even abandoning the affected areas.

Journal of Education and Learning , 2012,
Abstract: This study aimed to demonstrate the use of multiple indicators and multiple (MIMIC) model in testing the consistency of the measurement results when it's applied to individuals with different characteristics. Self-Esteem and Student Motivation Scale were employed to measure participant attributes. Impact of three student characteristics (gender, intelligence and school location) on both measurement model were examined. Total of 2981 students from 30 cities of 15 provinces were participated in this study. Data analysis was utilized using confirmatory factor analysis under structural equation modeling (SEM) approach. Results showed that measuring self-esteem was prone to be contaminated by individual heterogeneity. However, contrary results was found on motivation measure. Excluding three student characteristics as covariance in the model have increased model fit indices in the self-esteem measurement model, but not in the self-esteem. The presence of susceptibility scale to different characteristics indicated that this scale needs to be further modified. Therefore, when it is applied to heterogeneous population, the measurement results will produce consistently results.

Biodiversitas , 2006,
Abstract: The aim of this research was to know the abundance and natural food resources of birds in the Manusela National Park, Seram (Ceram), Central Moluccas. The observations were done by “line-transect methods”, which in observe 70.50 hours totality. The results were found 51 species of birds in area of the national parks and 4 of all, namely red lory (Eos bornea), papuan hornbill (Rhyticeros plicatus), shining starling (Aplonis metallica), and grey-necked friarbird (Philemon subcorniculatus) were abundant. Fourty seven species of plants were known useful for 19 species of birds as the natural food resources, nesting-sites and roosting trees.
Population Status of Cacatua sulphurea parvula and Trichoglossus euteles in Alor
Biodiversitas , 2009,
Abstract: The aim of this survey was to know the abundance status of the Yellow-crested Small Cockatoo (Cacatua sulphurea parvula) and Yellow-headed Lorikeet (Trichoglossus euteles) in Alor, East Nusa Tenggara Province. There were four sites observation in the survey, namely: (i) Air Mancur preparatory Village (in and around of Tuti Adigae Natural Tourism Park, East Alor Sub-district), (ii) Tanglapui Village (Kampong Irawuri) (East Alor Sub-district), (iii) Probur Village (Kampong Wormanem) (Southwest Alor Sub-district), and (iv) Bota Village (Northwest Alor Sub-district). The survey was used by bird encounter rates per unit time method. The population of birds approached by abundance score value. Fifty species of birds or 64.9% of 77 species of birds that found in Alor recorded during field working. The yellow-headed lorikeet observed more abundant with five abundance score and the numbers per 10 hours observation were 58.06. The yellow-crested small cockatoo no one recovered during in the survey. However, the yellow-crested small cockatoo knows in the fields in direct observation nesting in the old nest site of Canarium trees.

Abstract: The research of stock analysis of Metapenaeus elegans was held in Segara Anakan Lagoon, Cilacap CentralJava. This research were aimed to study the carapace length of optimal capture, exploitation rate optimumand maximum sustainable yield relative. The research were carried out by using survey method and thesample were collected by systematic random sampling method. Sampling conducted over 11 months, fromFebruary until December 2004. Data was analyzed using ELEFAN in FiSAT II software. The result showthat rate of exploitation of M. elegans was 0.83 / year, and the length of first capture of the M. elegans was14.5 mm. At 14.5 mm carapace length, the rate of exploitation (E) should be 0.51 / year, and E0.1 was 0.47 /year. The average biomass of exploited for 24% of the initial biomass, which has exceeded the ideal limit of10% (E0.1 concept). According to the above three indicators (the carapace length of shrimp, exploitation rateand biomass used), then the exploitation of M. elegans in Segara Anakan Lagoon has been consideredseriously over-exploited. The rate of exploitation has reached 154% of Emsy and 177% of E0.1. Based onsimulation results, the size of carapace length of first capture that produces the MSY is a minimum carapacelength of 21.3 mm, and the rate of exploitation (E) can reach 0.7 / year

Abstract: Land subsidence can have a considerable impact on the socio-economic viability of areas. In urban areas, land subsidence tends to damage buildings and infrastructures gradually, while in rural peat land it slowly destroys vegetation. The damages will worsen since climate change has further implications for the areas affected by land subsidence. In Indonesia, the response to land subsidence varies in different areas in terms of awareness, urgency and action on the part of both public authorities and land users. This paper systematically investigates these varied responses in urban and rural peat land areas. Interviews with experts and surveys of 330 land users in selected sub-districts were conducted and further supplemented by focus group discussions. We found that both the public authorities as well as the land users’ responses were considered as of limited value to contest land subsidence. We suggest that the endorsement of land users’ response into governmental policies would make a significant difference in improving land subsidence management.
