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: Integrasi MobileNet-SSD dan Isolation Forest untuk Implementasi Sistem Deteksi Anomali Pergerakan Ayam Berbasis Web
Abstrak: Dalam usaha ternak ayam broiler, kesejahteraan hewan merupakan salah satu aspek yang perlu diperhatikan peternak. Aspek dalam kesejahteraan hewan diantaranya adalah freedom from hunger or thirst (kebebasan dari kelaparan dan haus) dan freedom from pain, injury or disease (kebebasan dari rasa sakit, luka dan penyakit). Proses pemberian pakan secara terus menerus mengakibatkan meningkatnya massa ayam broiler, membuat ayam broiler menjadi kesulitan bergerak untuk mengambil makanan maupun air, yang mengakibatkan ayam broiler menjadi sakit kemudian mati. Tersedianya sistem yang dapat mendeteksi kesulitan bergerak pada ayam broiler akan memudahkan peternak dalam memantau pergerakan ayam broiler dari kejauhan. Dalam penelitian ini, deteksi ayam yang kesulitan bergerak dilakukan melalui integrasi model deteksi objek MobileNet-SSD dan algoritma deteksi anomali isolation forest dari penelitian sebelumnya. Integrasi dilakukan menggunakan bahasa pemrograman Python, diuji menggunakan video dengan kombinasi resolusi dan frame per second (FPS) tertentu, kemudian diimplementasikan menjadi sebuah aplikasi web menggunakan framework Flask. Hasil analisis integrasi menunjukkan bahwa semakin besar resolusi dan FPS video masukan, maka waktu inferensi dan waktu eksekusi dari sistem hasil integrasi menjadi semakin besar dan diestimasi meningkat secara linear., In the broiler farming business, animal welfare is an aspect that needs to be considered by breeders. Aspects of animal welfare include freedom from hunger or thirst and freedom from pain, injury, or disease. The process of continuous feeding results in broiler chicken's mass increase, making it difficult for them to move to get food and water, resulting in their sickness and death. The availability of a system that can detect the movement difficulty of the broiler chickens will make it easier for farmers to monitor the movement of broiler chickens from afar. In this study, the detection of chickens that had difficulty moving was carried out by integrating the MobileNet-SSD object detection model and the isolation forest anomaly detection algorithm from previous studies. Integration is carried out using Python programming language, tested using video with a combination of resolution and frame per second (FPS), then implemented into a web application using the Flask framework. The integration analysis shows that the greater the resolution and FPS of the input video, the greater the inference and execution time. Both times are also estimated to increase linearly.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
