Judul: Aplikasi Android untuk Pengenalan Citra Karakter Jepang dengan Library Tesseract
Abstrak: Japanese is one of difficult language to learn because the writing is relatively complicated and it has three kind of writing hiragana, katakana, and kanji. In this study, the Japanese character recognition system based on Android is designed to recognize Japanese character image and translate it into Indonesian using the library Tesseract OCR (Optical Character Recognition). OCR is a technique to convert non digital text into digital text or literally be interpreted as optical character recognition. In this study there were five functional requirements taking a picture with a camera, taking pictures form gallery, the conversion from image to text, text editing of Japanese character form OCR results, and display the results of Japanese text translations. Based on 10 samples of Japanese characters that have been tested, the accuracy values obtained from the test image from the camera around 80% and 94% image from the gallery. Besides test of applications using the questionnaire reached 91%. Thus this application is expected to be able to recognize the image of Japanese characters and translate them into Indonesian according to user needs.

Judul: Aplikasi Android Penerjemah Bahasa non-Latin dengan Pengenalan Citra Karakter
Abstrak: Bahasa dengan karakter nonlatin merupakan bahasa yang sulit untuk dipelajari karena penulisannya yang relatif rumit. Beberapa bahasa yang menggunakan karakter nonlatin antara lain Arab, Cina (sederhana), Rusia, Jepang, Korea, dan Thailand. Pada penelitian ini, suatu sistem pengenalan karakter nonlatin berbasis Android dirancang untuk mengenali citra karakter nonlatin menggunakan Tesseract library OCR (Optical Character Recognition) dan menerjemahkannya menjadi bahasa Indonesia dan Inggris menggunakan Microsoft Translator. OCR adalah teknik untuk mengubah teks nondigital menjadi teks digital atau dapat diartikan sebagai pengenalan karakter optik. Pada penelitian ini terdapat 8 kebutuhan fungsional, yaitu memilih bahasa asal, mengambil citra menggunakan kamera dan memotongnya, mengambil citra melalui galeri, melakukan konversi dari citra ke teks, mengedit teks nonlatin hasil OCR, memilih bahasa tujuan, menampilkan hasil terjemahannya, dan me-reset aplikasi. Berdasarkan 650 contoh karakter nonlatin yang terdiri dari 5 bahasa telah diuji, nilai akurasi terbaik yang didapat adalah 95.03% pada kondisi pencahayaan normal. Adapun faktor-faktor yang dapat mempengaruhi akurasi tersebut antara lain: intensitas cahaya, kemiringan, fokus, dan penulisan secara vertikal. Evaluasi usability menghasilkan nilai 82.4%. Kata

Judul: Salinity influence to mercury toxicity and the effect to milkfish (Chanos chanos Forsskal) physiologic conditions
Abstrak: Mercury is a very dangerous heavy metal that can damage nerve and enzyme system in fish body. This research aimed to knows mercury toxicity to milkfish with different salinity. It consisted of two steps; they were preliminary research (range value test and acute toxicity test) and main research (the salinity influence of mercury toxicity and milkfish’s physiologic condition). Range value test was done in fresh water consisting of five treatments (0, 0.006, 0.06, 0.6 and 6 mg Hg/l). Acute toxicity test also consisted of five treatments (0, 0.110, 0.195, 0.347 and 0.618 mg Hg/l). Moreover, main research consisted of one control and three treatments with three replications at the same concentrate of mercury 0.012 mg Hg/l. Those treatments were salinity 0 ppt, 10 ppt and 20 ppt. The result demonstrated that LC50 96 hour in fresh water was 0.147 mg Hg/l. The main research showed that mercury can increased osmotic gradient, decreased oxygen consumption rate, increased blood glucose rate, decreased hematologic conditions, growth rate, feeding efficiency, and survival rate. Mercury is collected in body gland, for example in gill and liver. Treatment C (10 ppt) showed better physiologic conditions than other treatments. The effect of mercury toxicity would get minimal while maintained at optimal salinity.
