The Newcastle disease virus (NDV) outbreak was first reported in Java Island, Indonesia, in 1926, which was then reported further in Newcastle-upon-Tyne, England. Nevertheless, the NDV is still endemic in Indonesia, with outbreaks occurring in free-range and commercial chicken farms. The dynamic evolution of the NDV has led to the further development of vaccines and diagnostic tools for more effective control of this virus. This paper discusses the history of the NDV occurrence, vaccines, the development of diagnostic tools, and the epidemiological condition of the NDV in Indonesia. Indonesia, which has the largest poultry population in the world after China, has challenges in preventing and controlling this virus that causes economic losses to the farmers and has an impact on the welfare of the poultry farming community in Indonesia.

This paper discusses the relationship between debt literacy, peer-to-peer lending, and over-indebtedness in Indonesia. It is essential because the number of loans on this platform continues to increase, both legal and illegal. Data was collected online in collaboration with commercial market research firms, JajakPendapat.net. Debt literacy and over-indebtedness were measured by self-assessment with questions from Lusardi and Tufano (2009a). Questions for debt literacy are about interest compounding, debt interest, and the application of time value of money in payment options. The question for over-indebtedness is about the amount of debt and the conditions resulting from that debt. By using descriptive methods, it is clear that the majority of respondents, both borrowers and non-peer-to-peer lending borrowers are debt illiterate, and those who have poor debt literacy have huge debt. Overall, only 1.85% of the respondents were debt literate. Those who live on the island of Java have better literacy because they are the center of economic growth in Indonesia. Debt from peer-to-peer (P2P) lending also has the potential to create problems, namely over-indebtedness. P2P lending borrowers also have very poor debt literacy. However, there is no difference in debt literacy between P2P lending borrowers and non-P2P lending borrowers.

Faith-based investment instruments, such as sharia-based stocks, have developed rapidly in recent years. When investing in these instruments, investors tend to emphasize materialistic returns as measured with monetary returns and metaphysical returns, such as blessings from God (Allah) because of their observance of Islamic teachings. In this respect, it is important to investigate the role of individuals' religiosity in investment decision making in Sharia-based financial products. An equally crucial research question is whether individuals' religiosity levels affect expected material returns as measured by the tolerable negative returns of sharia-based stocks. This study relies on a survey method that involves university students in Java island who actively invest through the Investment Gallery of their faculties/ universities as the sample. Data is then analysed with the multinomial regression analysis technique. The results show that individuals who are more observant of their religious teachings are more likely to fully invest their funds in Sharia-based stocks and exhibit greater tolerance towards the negative returns of Sharia-based stocks. The findings indicate that Muslim investors who are more observant of Islamic teachings emphasize metaphysical returns from their investment decisions.

Purpose: This article discusses public acceptance in the information distribution of Copyright Law no. 28 of 2014 and Government Regulation No. 56 of 2021 in Indonesia concerning the commercial use of music. Hospitality industry is one of the most affected by this regulations, which some hotelsrefused to comply. To get royalties, LMKN approaches with socialization either directly or indirectly to commercial music users. Research design, data and methodology: Quantitative survey by distributing questionnaires, then testing the validity and reliability tests using the SmartPLS application. The population studied were Hotels on Java and Bali Island in Indonesia. The research sample is 100 hotels. Result: R-Square value of 0.706 for the construct (Y) User Response which means that (X) Socialization can explain the variance (Y) User Response of 70.3%. This shows that the level of influence (X) Socialization has an effect on (Y) User Response. Conclusion: User responses regarding the distribution information of the Act indicate the need for socialization, because socialization provides literacy to the public. More frequent socialization will provide a good opportunity to increase the response of commercial music users.

This paper proposes a system that can serve users with appropriate search results through real time filtering, and implemented adaptive user profiling based personalized information retrieval system(PIRS) using users' implicit feedbacks in order to deal with the problem of existing search systems such as Google or MSN that does not satisfy various user' personal search needs. One of the reasons that existing search systems hard to satisfy various user' personal needs is that it is not easy to recognize users' search intentions because of the uncertainty of search intentions. The uncertainty of search intentions means that users may want to different search results using the same query. For example, when a user inputs "java" query, the user may want to be retrieved "java" results as a computer programming language, a coffee of java, or a island of Indonesia. In other words, this uncertainty is due to ambiguity of search queries. Moreover, if the number of the used words for a query is fewer, this uncertainty will be more increased. Real-time filtering for search results returns only those results that belong to user-selected domain for a given query. Although it looks similar to a general directory search, it is different in that the search is executed for all web documents rather than sites, and each document in the search results is classified into the given domain in real time. By applying information filtering using real time directory classifying technology for search results to personalization, the number of delivering results to users is effectively decreased, and the satisfaction for the results is improved. In this paper, a user preference profile has a hierarchical structure, and consists of domains, used queries, and selected documents. Because the hierarchy structure of user preference profile can apply the context when users perfomed search, the structure is able to deal with the uncertainty of user intentions, when search is carried out, the intention may differ according to the context such as time or place for the same query. Furthermore, this structure is able to more effectively track web documents search behaviors of a user for each domain, and timely recognize the changes of user intentions. An IP address of each device was used to identify each user, and the user preference profile is continuously updated based on the observed user behaviors for search results. Also, we measured user satisfaction for search results by observing the user behaviors for the selected search result. Our proposed system automatically recognizes user preferences by using implicit feedbacks from users such as staying time on the selected search result and the exit condition from the page, and dynamically updates their preferences. Whenever search is performed by a user, our system finds the user preference profile for the given IP address, and if the file is not exist then a new user preference profile is created in the server, otherwise the file is updated with the transmitted information. If the file is not exist in the server, the system provides Google' results to users, and the reflection value is increased/decreased whenever user search. We carried out some experiments to evaluate the performance of adaptive user preference profile technique and real time filtering, and the results are satisfactory. According to our experimental results, participants are satisfied with average 4.7 documents in the top 10 search list by using adaptive user preference profile technique with real time filtering, and this result shows that our method outperforms Google's by 23.2%.

Recently the navigation service and LBS (Location based Services) using map supports much information services on mobile terminal. Also Internet Web sites support user much information. But, the user has the difficulty for acquiring the service and the various information based on map because of searching the many Internet sites. Accordingly, this paper supports a convergence information service model of various culture, education, tourism, sport and traffic for accessing synthesizing information based on map. And we design and implement this model using 공개 API. We present a convergence information service model of culture, tourism, sport and bus line information form tour destination and cultural place of Jeju province using the model. Additionally, we develop this service model using apache web server on Linux environment, PHP and JavaScript, MySQL database and Map 공개 API. As this service model supports a convenience action of culture and tourism for Jeju islanders and tourists.

In this study, the number of theses conducted in 1990's for the master's degree in mathematics education was investigated in terms of their fields and themes. These theses were analysed as to how much they had been studied according to the field and whether they had conformed to the expectations and requirements for research in mathematics education under the current educational curriculum. Futhermore, this study aimed to discover advancing directions of research in mathematics education. The results are as follows: First, the rate of annual thesis presentations decreased as many as 3.82% in 1994 compared with the previous year, but the rate increased steadily in the other years showing an overall annual average increase of 8.41%. Second, in the geographical distribution of thesis presentations among local provinces, Seoul represented the highest frequency at 41.13% and Cheju Island the lowest at 1.68%. When the annual thesis presentations were analysed among regions, their number increased steadily in Seoul, but fluctuated in most other regions. Third, regarding study themes, theses on mathematics education formed 70.91% of the total while those focusing on pure mathematics formed 29.09%. Among the theses of mathematics education, most were based on teaching curriculums and the least were based on education assessment. Among the theses on teaching curriculum, teaching analytics formed the highest rate. Theses on education technology, such as computerizing and computing, have shown to be increasing annually and formed 8.95% of the total in 1999. The study also indicated that especially in the late 1990's, there have been many designed programs based on the Web, like JAVA and CGI, and studies on teaching and teaming methods using the internet.

This study is thing about eco-tourism activated Mt. Gede Pangrango National Park in Indonesia. Indonesia is full of eco-tourist resources with the possession of the tropical forest. Particularly, Gede Pangrango National Park on the west of Java island has so plenty of bio-diversity that the UNESCO designated this park as the World Biosphere Reserve. By virtue of this, various visitors all over the world are visiting Gede Pangrango Park for doing research, education, hiking and camping. However, Indonesia lags behind other countries in convenience facilities for visitors, so their visiting programs are actually insufficient. In order for eco-tourism to be revitalized, there should be physical improvement in visiting facilities, management of a variety of visit programs, and local residents' participation & projects to increase the income of local residents. This study is going to seek for the environment-friendly management plan suited for the properties of the park and improvement plan for eco-visiting facilities by closely grasping the actual condition of the eco-tourism of Gede Pangrango National Park.

As Indonesia determines to increase its marine fishery production, the development of tradi-tional boatyards has to be included in the agenda as it will give the local fishing communities a better chance to compete with large capital intensive fishing companies. It will also spread job opportunities evenly throughout the country instead of concentration fishing vessel con- struction in a few large shipyards located primarily on the highly populated island of Java. However development every single boatyard in indonesia would not only be prohibitively ex-pensive, but it would also create social tensions as the introduced technology would not be immediately accepted by the rural societies whose own traditions are still culturally signif-icant. Both these problems can be reduced by developing a collaborative scheme between traditional boatyards and a larger shipyard. The shipyard, with modern facilities, can develop work packages containing knock down components which are then assembled in the tradi-tional boatyards. The work packages are planned and designed so that every component can be assembled with relatively simple tools. Radical changes can be avoided as new techniques can be introduced gradually, responding to the boatyard\\`s own requirements and aspirations. While this manufacturing procedure is conceptually straightforward its efficient implemen-tation is in practice complicated by the fact that each traditional boatyard has unique char-acteristics in terms of labour resources, technological capability, and transportation links. By developing a computer model to simulate the interaction between the main shipyard and small traditional a computer model to simulate the interaction between the main shipyard and small traditional boatyards work packages can be designed that ensure that activities at all manufacturing locations are efficient.

There are 82 volcanoes active during the 48 weeks of 2019 (January 30 to December 31, 2019; USGS data) Approximately 80~90 volcanoes are active on the Earth for a year. More than 91% of these volcanoes are took place in the circum-Pacific volcanic belt, which is commonly called 'Ring of Fire'. This status coincides with the distribution maps of active volcanoes on the earth: about 80 percent on subduction zone of the convergent plate boundaries; 15 percent on divergent plate boundaries; 5 percent on intra-plate zone. Typically five volcanoes are most active during the survey period (48 weeks); Dukono (Halmahera, Indonesia) 48 times, Aira (Kyushu, Japan) 47 times, Ebeko (Paramushir Island, Russsia) 46 times, Merapi (Central Java, Indonesia) 37 times, Krakatau (Indonesia) 33 times. The comparison of volcanic activity between 2018 and 2019 showed no significant difference. It is assumed that volcanic activity remains stable.
