Abstract

The objective of this study is to map the change dynamic of dengue endemic area in Salatiga, Central Java in 2001-2008. This study is carried out in three stages. The first one is the descriptive survey to find the secondary sociodemographic and epidemiologic data. The second stage is data analysis using spatial association, in this case is Global Moran’s dan Local Moran’s (LISA). The last stage is the interpretation of the result of analysis in form of Moran Scatterplot and LISA map. The result of the study shows that spatial pattern based on the dynamic distribution of Dengue occurrence could be identified using Global Moran’s method. From 2001 to 2008, it could be found that there are hotspots and outlier. The area with high frequency of hotspot is Sidorejo Lor, Mangunsari and Kutowinangun. Using Local Moran’s I method, the spatial pattern of the distribution of dengue could be visualized in form of LISA (Local Indicator Spatial Association) map. The map is categorized into HH, HL, LH dan LL. The ABJ value is not significant with the dengue happenings in each village. The area with high ABJ is not followed by the high value of dengue happening. Based on the choropleth, it could be described that the dengue happening is caused by the dense of the population. The result of this study could be used as a tool to control and identify the cause of dengue.

Abstract

Nowdays, flood should not be a problem for a big city like Surabaya. But in the reality, some areas still have this problem, including ITS's area. There are some areas in which the water stucks and can't flow anywhwere in a long enough period, eventhough they have five pumps of flood. The analysis is based on some factors, the elevations data and the closest point of the waste water channel. The lowest elevation from every area is a place where the water can't flow anywhere, so we must place the pump to the area. The waste water channel also a factor to determine the pump's location. The closer the flood's pump to the waste water channel, the easier the stuck water in lowest areas can be pumped to the big water's stream. The software has already benchmarked with the exist pump's location. The calculation result from the expresion shows that the calculation is appropiate with the manual calculation. It shows that we can use the system to find the efective pump's location and calculate the capacity of the flood's pump technically. Abstract in Bahasa Indonesia : Saat ini, banjir semestinya sudah bukan merupakan masalah, terutama bagi kota besar seperti Surabaya. Tetapi kenyataannya, beberapa areal masih juga mempunyai masalah tersebut, tidak terkecuali areal ITS. Masih ditemukan beberapa areal yang mengalami genangan air cukup lama, padahal telah terpasang lima pompa banjir. Analisis dipengaruhi oleh beberapa faktor serta pemberian bobot pada data elevasi dan titik terdekat saluran pembuangan air. Elevasi terendah di setiap areal adalah tempat genangan air terjadi, oleh sebab itu pemasangan pompa banjir selalu berada di tempat tersebut. Saluran pembuangan air juga merupakan faktor dalam penentuan letak pompa banjir. Semakin dekat pompa banjir dengan saluran pembuangan air, maka air yang terkumpul pada setiap areal dapat dipompa ke saluran besar. Perangkat lunak yang telah dibuat telah diujicobakan dan kemudian dibandingkan dengan letak pompa banjir yang telah ada. Hasil perhitungan dengan menggunakan rumus yang telah ada, menunjukkan bahwa perhitungan perangkat lunak ini telah sesuai dengan perhitungan manual yang didapatkan. Hal tersebut menunjukkan bahwa sistem dapat dimanfaatkan dalam mencari letak pompa banjir yang efektif dan menghitung kapasitas pompa banjir secara teknis. Kata kunci: letak pompa, kapasitas pompa, banjir.

Abstract

The relational data model approach is still used broadly in developing of data and information storage of the most application systems. The main restricted of using the relational model data das not support dynamically in storing information in which much more semantically of the knowledge must be kept on that data. On other hand, if information intend to be considered more formally concrete knowledge as in reality, it's difficult to retrieve the persistent data or information on the various ways of the user need. This paper has researched, analysed, and discussed of data modelling by using an ontology model based approached on constructing the data bank of flight schedule information as knowledge bases model. A protégé ontology software is used to arrange a model of flight schedule information in form of classes hierarchical, slots, and instances. The flight ontology model that has built can indicate much more semantics of flight schedule information. Additionally, the model can be used easily in form of many way of user perception need in order to make queries and results. Abstract in Bahasa Indonesia : Pendekatan model data relasional masih banyak dimanfaatkan untuk menyimpan data dan informasi terhadap banyak sistem aplikasi. Namun kendala utama menggunakan model relasional yang masih dirasakan hingga saat ini, adalah model data relasional kurang dinamis untuk mendukung penyimpanan informasi yang lebih bermakna secara semantis. Atau jika informasi yang disimpan dapat dipandang sebagai pengetahuan-pengetahuan yang lebih kongkrit, maka untuk melakukan pencarian dengan berbagai variasi pengetahuan terhadap data dan informasi akan menjadi sangat terbatas. Pada makalah telah diteliti, dianalisis, dan dibahas pemanfaatan sebuah pendekatan model data berbasis ontologi untuk menyimpan suatu basis data pengetahuan jadwal penerbangan. Dengan menggunakan protégé, model pengetahuan jadwal penerbangan disusun kedalam bentuk ontologi secara hirarki kelas, slot, dan instant. Model ontologi yang disusun mampu mendeskripsikan informasi jadwal penerbangan secara lebih semantis. Dan disamping itu, dari model yang telah dikembangkan menunjukan bahwa berbagai cara pengguna (menurut persepsi masing-masing) untuk melakukan pencarian informasi penerbangan ataupun hasil query dapat dibentuk secara lebih mudah. Kata kunci: semantis ontologi, manajemen pengetahuan, informasi cerdas, proses pengembangan ontologi.

Abstract

Taking attendance from employees always becomes a problem for Human Resource Department (HRD) in many companies lately. Although there is an automatic check-lock machine, it still has a weakness. This machine can't detect some frauds like the employee swipes double identity card, his card and the others card. Reseachers want to solve this problem by using data mining method, especially market basket analysis.This software will transform the attendance data to compact transaction format by using MaxDiff Histogram method. And it will be processed into frequent itemset with Pincer Search Algoritm. At the final process the employee's association rule will got from frequent itemset. This output will be served to user that is the HRD of a firm.Testing result shows that Data Mining Market Basket Analysis can be used to get pattern of employee's check-lock from a company. And this pattern can help user to detect fraud that is done by employee. Abstract in Bahasa Indonesia : Absensi pegawai selama ini selalu menjadi permasalahan yang pelik bagi bagian HRD di perusahaan - perusahaan yang ada. Walaupun telah ada peralatan absensi otomatis, alat ini masih memiliki kelemahan yaitu, tidak dapat mendeteksi kecurangan pegawai untuk menitipkan kartu absensinya pada karyawan lain untuk diabsenkan. Peneliti berkeinginan untuk mengatasi permasalahan absensi tersebut dengan memanfaatkan metode data mining, khususnya metode market basket analysis, untuk mendeteksi kecurangan ini.Perangkat lunak yang dibuat ini akan mentranformasikan data absensi pegawai menggunakan metode MaxDiff Histogram menjadi format compact transaction yang selanjutnya akan diproses menggunakan Algoritma Pincer Search menjadi frequent itemset. Pada akhirnya dari data frequent itemset ini didapat association rule pegawai untuk disajikan kepada pengguna, yaitu bagian HRD perusahaan.Dari hasil pengujian dapat diketahui bahwa metode Data Mining Market Basket Analysis dapat dimanfaatkan untuk menggali pattern kebiasaan absensi (check-lock) pegawai sebuah perusahaan. Dari sini kemungkinan terjadinya kecurangan saat melakukan absensi masuk / pulang dapat dideteksi.

Abstract

This paper presents a project of Web-based Distance Learning support system. The system has been built based on the Internet and World Wide Web facility. The system could be accessed with a web browser which is directed to a certain web server address so that students can do learning process just like in the real situation, such as student admissions, taking course materials, syllabus, assignments, students grades, class discussions through web, and doing online quizzes. Students could also join collaboration works by giving opinions, feedback and student produced paper/web which can be shared to the entire learning community. Therefore, it will build a collaborative learning environment where lectures together with students make constructive knowledge databases for entire learning community. This system has been developed based on Active Server Pages (ASP) technology from Microsoft which is embedded in a web server. Web pages reside in a web server which is connected to an SQL Database Server. Database server is used to store structured data such as lectures/students personal information, course lists, syllabus and its descriptions, announcement texts from lecturers, commentaries for discussion forum, student's study evaluations, scores for each assignment, quizzes for each course, assignments text from lectures, assignments which are collected by students and students contribution/materials. This system has been maintained by an administrator for maintaining and developing web pages using HTML. The administrator also does ASP scripts programming to convert web pages into active server pages. Lectures and students could contribute some course materials and share their ideas through their web browser. This web-based collaborative learning system gives the students more active role in the information gathering and learning process, making the distance students feel part of a learning community, therefore increasing motivation, comprehension and interaction with other students.

Abstract

The central problem of most Content Based Image Retrieval approaches is poor quality in terms of sensitivity (recall) and specificity (precision). To overcome this problem, the semantic gap between high-level concepts and low-level features has been acknowledged. In this paper we introduce an approach to reduce the impact of the semantic gap by integrating high-level (semantic) and low-level features to improve the quality of Image Retrieval queries. Our experiments have been carried out by applying two hierarchical procedures. The first approach is called keyword-content, and the second content-keyword. Our proposed approaches show better results compared to a single method (keyword or content based) in term of recall and precision. The average precision has increased by up to 50%.
