    Abstract FTI UK Petra akan membangun pabrik garmen mini yang membutuhkan robot otonom. Robot otonom ini akan melakukan tugas material handling dalam pabrik tersebut. Oleh sebab itu, penelitian ini bertujuan untuk merancang perangkat lunak untuk mendukung tugas tersebut. Adapun robot otonom ini tergolong sebagai AMR (Autonomous Mobile Robot) karena dapat bergerak bebas pada lingkungan tanpa memerlukan bantuan garis atau tanda lainnya. Robot ini dilengkapi dengan sensor LIDAR untuk mendeteksi keadaan lingkungan sekitarnya secara 360 derajat. Dengan adanya sensor ini robot dapat melakukan pemetaan terhadap pabrik garmen dengan memanfaatkan metode SLAM. Robot juga dapat melakukan navigasi secara otonom dengan memanfaatkan pembacaan Sensor LIDAR dan algoritma DWA. Dari penelitian yang telah dilakukan, penulis menemukan bahwa perangkat lunak yang telah didesain mampu melakukan navigasi otonom dengan waktu yang kurang lebih sama dengan navigasi secara teleoperasi dan robot mampu mendeteksi QR Code pada jarak 10-20 cm menggunakan kamera. Dengan demikian, penelitian ini telah berhasil menghasilkan perangkat lunak untuk robot otonom yang akan digunakan pada pabrik garmen mini.

    Abstract This paper proposes a method that automatically finds human faces as well as its landmark points in color images based on a fuzzy analysis. The proposed approach first uses color information to detect face candidate regions and then uses a fuzzy analysis of the color, shape, symmetry and interior facial features. A deformable Gabor wavelet graph matching is used to locate the facial landmark points describing the face. The latter allows for size and orientation variation since the search for landmark points allows for affine transformations as well as local deformations of the Gabor wavelet graph. The search is performed using a genetic algorithm that is essential because it effectively searches the solution space. Results based on the proposed method are included to verify the effectiveness of the proposed approach. Abstract in Bahasa Indonesia : Paper ini mengusulkan sebuah metode deteksi wajah beserta dengan titik landmarknya pada citra berwarna menggunakan analisa fuzzy. Proses awal menggunakan informasi warna kulit untuk menseleksi calon-calon obyek lantas dilanjukan dengan analisa fuzzy terhadap warna, bentuk, simetri dan fitur/landmark wajah. Proses lokalisasi landmark wajah menggunakan Gabor wavelet graph matching dengan memaksimalkan kemiripan antara landmark wajah model dengan obyek inputan. Proses maksimalisasi kemiripan ini menggunakan algoritma genetika. Hasil-hasil percobaan ditampilkan untuk memberikan gambaran keberhasilan dari metode yang diusulkan. Kata kunci: lokalisasi landmark wajah, analisa fuzzy, graph matching, algoritma genetika, Gabor wavelet.

    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 Data mining application with fuzzy c-covering method for market basket analysis on supermarket. As one of data mining applications, market basket analysis is generally performed using apriori method. However this method tends to searh the association degree of items by only counting how many times the items appears on the overall transaction without considering the items quantity on each transaction. Therefore, we propose a new method which is based on perception that the more items bought in a transaction, the weaker the relation between items on that transaction. For the experimental purpose of the realization the concept, we collect a month sales transaction data from a supermarket. The data are transformed to another form that can be used by the software. Then, an algorithm is created to process the data in order to generate association rule of items in transaction. The rules can be previewed in a table or graphic. Borland Ceplhi 7 and MS Access 2003 is used to build this experiment software. By using the output of this software, which are the association rules, association degree of items, can be obtained which is useful to help the decision maker to make market policies. Based on the testing result, it can concluded that the smaller minimum support and confidence, the more rule to be generated and the more processing time needed. Also, the higher the combination count to be searched, the less processing time needed. Abstract in Bahasa Indonesia : Sebagai salah satu aplikasi data mining, market basket analysis umumnya dilakukan dengan memakai metode Apriori. Metode ini mencari asosiasi antar item dengan hanya menghitung berapa kali item-item tersebut muncul dalam keseluruhan transaksi tanpa memperhatikan quantitas item dalam transaksi. Oleh karena itu, peneliti mengusulkan metode Fuzzy c-Covering. Metode ini didasarkan pada persepsi bahwa semakin banyak item yang dibeli dalam suatu transaksi, maka hubungan antar item dalam transaksi tersebut semakin lemah. Untuk pengujian realisasi konsep tersebut, peneliti ...

    Abstract The number of paper collected by an educational institution is incresing each year. The increasing number of paper collected demand a method in order to find the right paper everytime there is someone who needs a reference. By far, most search engine still depend on keyword matching / string maching to find the apropriate result. This method will only find the apropriate paper based on the occurance of the inserted keyword on the paper. This research will discuss a searching system using fuzzy relation, by using fuzzy relation the relation between keyword and paper is found and determined. Searching system using fuzzy relation allows the search result include paper that do not have the keyword to be shown as a result. This result is made posssible because the word which occur in the paper is related to keyword inserted. Abstract in Bahasa Indonesia : Banyaknya jumlah paper yang dikoleksi sebuah lembaga pendidikan setiap tahun akan bertambah. Seiring dengan pertambahan jumlah paper tersebut maka diperlukan sebuah metode untuk mencari paper agar bila membutuhkan referensi maka paper/dokumen yang diperlukan dapat dengan mudah dapat ditemukan. Sejauh yang ada saat ini, kebanyakan mesin pencari masih mengandalkan pencarian dengan menggunakan keyword matching/string matching sehingga mengakibatkan hasil pencarian hanya akan menampilkan paper-paper yang mempunyai keyword/kata kunci yang dicari. Penelitan ini membahas sebuah sistem pencarian dengan menggunakan metode fuzzy relation, dimana dengan fuzzy relation didapatkan hubungan antara keyword dan paper. Dengan metode fuzzy relation maka sebuah pencarian mempunyai kemungkinan menampilkan hasil berupa paper yang tidak mengandung keyword yang dicari. Karena kata yang mengakibatkan paper (yang tidak mengandung keyword muncul) mempunyai hubungan dengan keyword yang dimasukkan. Kata kunci: mesin pencari, relasi fuzzy, sistem cerdas.
