Judul: Aplikasi Pengelolaan Parkir Satu Pintu Berbasis Mobile Android Dengan Pengenalan Karakter Optik
Abstrak: Beberapa area parkir di kampus IPB masih menggunakan pencatatan kendaraan parkir secara manual oleh satpam. Penelitian ini menghasilkan sebuah aplikasi M-Parking pada mobile phone berbasis Android. Aplikasi akan mengenali citra karakter id kartu parkir dengan menggunakan library Tesseract OCR (Optical Character Recogntion). Beberapa kebutuhan fungsional utama pada aplikasi di antaranya mengambil foto id kartu dengan kamera atau galeri, menampilkan teks id kartu hasil OCR, menyimpan id kartu dan foto kendaraan, mencari id kartu berdasarkan rentang waktu, menampilkan foto kendaraan dan biaya parkir. Berdasarkan 350 data uji kartu parkir, nilai akurasi OCR terbaik adalah 100% pada kondisi pencahayaan normal, sangat terang, redup, dan citra dalam keadaan kabur. Faktor yang paling mempengaruhi akurasi adalah kemiringan teks id kartu. Adapun efisiensi waktu yang didapatkan oleh aplikasi dibandingkan dengan sistem manual yakni 3.64 detik lebih cepat pada saat kendaraan masuk dan 2.15 detik lebih cepat pada saat kendaraan keluar. Evaluasi usability pada aplikasi menghasilkan nilai 93.6%.

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: Acute Oral Toxicity Lethal
Dose 50 (LD50) of Cayenne Pepper (Capsicum annuum) Infusion in DDY Strain
Mice (Mus musculus)
Abstrak: In recent years, there has been a growing interest in herbal remedies such as cayenne pepper which is known for its versatility beyond its culinary use. Cayenne pepper’s phytochemicals, including capsaicinoids, carotenoids, phenolic compounds, vitamins, and minerals, offer antioxidant, antimicrobial, and antiinflammatory properties, making it a valuable ingredient in various fields such as veterinary medicine, agro-food, cosmetics, and pharmaceuticals. However, concerns regarding the potential risks of cayenne pepper consumption as herbal medicine arise. This study aims to determine the acute oral toxicity lethal dose 50 (LD50) of cayenne pepper infusion in female DDY strain mice and its effects on the mice's organs. The research involved 20 DDY strain female mice divided into 4 groups which are control group (administered with distilled water) and treatment groups that are given cayenne pepper infusion at doses of 5, 10, and 15 g/kg BW orally. The observed variables included mortality, clinical symptoms, physiological responses, and organ weight. Acute toxicity testing indicated that the cayenne pepper infusion falls into the category of practically non toxic formulations. Administration of the cayenne pepper infusion up to a dose of 15 g/kg BW did not induce toxicity symptoms, such as clinically pathological symptoms, macro anatomical organ changes, or mortality nor affect both weight gain and loss.
