Judul: Implementasi Strongsort Dengan Yolov5 Untuk Pendeteksian Posisi Bangkai Ayam Dari Data Video
Abstrak: Dalam peternakan ayam, jika bangkai ayam tidak dibuang dengan cepat dari kandang ayam, akan meningkatkan resiko tersebarnya penyakit unggas. Oleh karena itu, suatu metode yang dapat mendeteksi bangkai ayam secara cepat akan sangat berguna untuk peternak ayam. Penelitian ini mengajukan untuk menggunakan Object Tracking sebagai metode pendeteksian bangkai ayam. Model Object Tracking yang digunakan adalah StrongSORT yang dibantu dengan metode Object Detection YOLOv5. Data video dari 8 kamera CCTV kandang ayam Fakultas Peternakan akan digunakan sebagai data pelatihan dan pengujian. Object Tracking akan dijalankan terhadap data tersebut. Akan disimulasikan data yang akan merepresentasikan data bangkai ayam. Hasil penelitian mendapatkan akurasi klasifikasi terbaik terendah 92% dan tertinggi 99%, In poultry farming, if carcasses are not quickly disposed of, they will increase the risk of spreading diseases. Therefore, a method that can quickly detect chicken carcasses will be very useful to poultry farmers. This research proposes to use Object Tracking as said method. StrongSORT is chosen as the object tracking model with the help of YOLO v5 as an Object Detection model. Video Data from 8 CCTV from Faculty of Animal Science’s chicken shed will be used as training and testing data. Object Tracking will be executed on said data. Data will be simulated which will represent chicken carcass data. The result of the research the best accuracy of classifiers at worst is 92% and at best 99%

Judul: Multi-Object Tracking (MOT) Algorithm Implementation for Poultry Behavioral Analysis
Abstrak: Ayam merupakan salah satu hewan ternak yang paling banyak dikonsumsi di Indonesia. Selain itu kesadaran akan kesejahteraan hewan (animal welfare) juga semakin meningkat di dalam maupun luar negeri. Dengan meningkatnya persaingan dagang antar peternak dan kebutuhan untuk memenuhi standar yang berlaku, dibutuhkan cara untuk melakukan efisiensi jumlah dan jadwal pemberian pakan serta pengawasan terhadap ternak ayam. Analisis kebiasaan ternak ayam dapat dilakukan untuk mengatasi hal tersebut. Penelitian ini bertujuan untuk mengimplementasikan algoritme Multi-Object Tracking untuk deteksi pergerakan banyak ternak ayam sebagai landasan awal pembuatan model analisis perilaku ternak ayam. Model yang dihasilkan berhasil menelusuri pergerakan banyak objek dengan tingkat presisi 60.4%.

Judul: Lejeuneaceae Subfamily Ptychanthoideae (Hepaticae) in  West Java
Abstrak: Subfamily Ptychanthoideae of the family Lejeuneaceae (Hepaticae) in West Java is still poorly known. Publications on this subfamily are out of dated and written in the 19th or early of 20th century. The last taxonomic treatment of Ptychanthoideae of West Java was in 1933, many species names have changed since then. Studies on Ptychanthoideae of West Java are urgently needed. Studies on the Ptychanthoideae were based on the specimens collected from West Java. A total number of 361 of specimens deposited in the Herbarium Bogoriense (BO), Herbarium Biotrop (BIOT), Gottingen Herbarium (GOET) and Bangi Herbarium (UKMB) were examined, those are old and several recent specimens collected in West Java. Recent collections were made from Telaga Warna, Ciater, Gunung Halimun Salak National Park, Cibodas Botanical Garden, Bodogol Education Center and Conservation (Gunung Gede Pangrango National Park), University of Indonesia Campus Depok, including several collections from Banten Province. Twenty four species of Lejeuneaceae subfamily Ptychanthoideae are known from West Java, belonging to 8 genera namely Acrolejeunea (Spruce) Schiffn. (2 species), Archilejeunea (Spruce) Schiffn. (1 species), Lopholejeunea (Spruce) Schiffn. (10 species), Mastigolejeunea (Spruce) Schiffn. (3 species), Ptychanthus Nees (1 species), Schiffneriolejeunea Verd. (1 species), Spruceanthus Verd. (2 species) and Thysananthus Lindenb. (4 species). Two new records of Ptychanthoideae: Mastigolejeunea indica Steph. and Thysananthus minor Verdoorn are reported for Java. A determination key to the species is presented including their descriptions and illustrations.
