Perpindahan panas sangat penting untuk diperhatikan. Solusi numerik dari persamaan konduksi panas yang diterapkan pada batang baja 1-dimensi dilakukan untuk mengamati perpindahan panas pada baja. Skema beda hingga kompak pada metode Crank-Nicolson memberikan solusi numerik persamaan konduksi panas pada batang baja 1-dimensi dengan tingkat akurasi yang sangat tinggi.

The surveillance camera system is widely used by the public. The surveillance camera system used is usually a CCTV camera. In general, CCTV cameras can only record video. Security monitoring or monitoring by CCTV cameras can only be effective if there are operators who see the record directly on a monitor. Actually the surveillance camera system can be programmed to give a warning sign to the user. The surveillance camera used in this study is the IP camera. The camera is a camera that can be programmed to provide a notification to the user. By implementing motion-based tracking technology on the surveillance camera system can detect movement. Kalman filter is one of the motion-based tracking methods. Kalman filters can predict the movements recorded by the IP camera. The results of this study state that the surveillance camera system can provide notification messages to users via an android device when the surveillance camera records the movement of human objects.
Dalam aplikasi bidang teknik, sangat sering digunakan bahan logam terutama besi sebagai bahan pembuatan pipa. Salah satu manfaat pipa besi yaitu dalam proses transfer gas. Dalam proses tersebut, gas serta pipa transfer sangat rentan terhadap panas. Skema beda hingga yang diterapkan pada metode numerik Crank-Nicoson memiliki tingkat ketelitian yang sangat baik. Skema tersebut digunakan untuk analisis proses penyebaran konduksi panas pada pipa besi yang berisi gas oksigen. Proses penyebaran panas pada pipa besi terjadi dengan mempertahankan syarat batas yang telah ditentukan.
Mikroalga merupakan salah satu potensi alam Indonesia yang dapat dimanfaatkan dalam berbagai kebutuhan seperti menghasilkan produk energi (bioethanol, biodiesel), biopolymer penghasil plastik dan sebagai bahan campuran tanah untuk rekayasa konstruksi, bahkan sebagai pengolahan limbah dengan cara menyerap kandungan senyawa organik dan nutrisi yang masih tersisa ataupun menyerap beberapa senyawa berbahaya yang terdapat dalam limbah. Salah satu media kulturisasi mikroalga adalah chemostat. Chemostat merupakan jenis bioreaktor kontinu yang berfungsi untuk budidaya mikroalga dan mikroorganisme yang lain yang biasanya digunakan dalam skala laboratorium dan industri. Penelitian ini membahas tentang kendali optimal berupa pemberian tingkat pengenceran secara optimal pada model pertumbuhan mikroalga dalam chemostat. Metode yang digunakan untuk menyelesaikan masalah kendali optimal ini adalah Prinsip Minimum Pontryagin. Adapun fungsi tujuan yang digunakan berupa meminimumkan waktu yang dibutuhkan oleh state awal untuk menuju state akhir (kondisi setimbang). Kemudian dilanjutkan dengan simulasi numerik menggunakan toolbox ICLOCS2. Simulasi dilakukan untuk mengetahui perbandingan pertumbuhan mikroalga dalam chemostat dengan dan tanpa kendali optimal. Berdasarkan hasil pembahasan diperoleh bahwa jenis kendali yang dilakukan berupa kendali bangbang. Hasil simulasi menunjukkan bahwa massa jenis mikroalga mampu mencapai kondisi setimbang 40.9% lebih cepat saat diberi kendali optimal daripada tanpa diberi kendali optimal.
