    The necessity for electrical energy has been currently significant to support economic growth in Indonesia, expected to annually increase every year. The increasing demand for electricity denotes that the electrical energy supplied by the generator is relatively large. In general, electricity generation in Indonesia utilizes fossil fuels in the generation process thus it creates emissions in the form of carbon dioxide (CO2), which are released into the air in large quantities. Therefore, planning is deemed instrumental, thereby encouraging that generation scheduling at an economical cost is required in the generation of each unit in order to adjust the load that changes every time. This final project discusses the problem of unit commitment (UC) with the addition of a carbon capture and storage (CCS) system in the generator. The Carbon Capture and Storage (CCS) process refers to a technology capturing up to 85% of carbon dioxide (CO2) emission as, the result of utilizing fossil fuels in electricity generation and industrial processes to prevent carbon dioxide from entering the atmosphere. The optimization algorithm utilized in this final project is the Firefly Algorithm (FA). The objective function that will be optimized lies in the cost of generation, scheduling on and off for each generator and carbon dioxide (CO2) emissions. The data used in this optimization includes the IEEE of 30 bus system and the addition of Carbon Capture and Storage Plants. The test results indicate that the FA method is able to perform UC calculations considering Carbon Capture and Storage

    Flood forecasting is crucial for early warning system and disaster risk reduction. Yet the flood river water levels are difficult and challenging task that it cannot be easily captured with classical time-series approaches. This study proposed a novel intelligence system utilised various machine learning techniques as individual models, including radial basis function neural network (RBF-NN), adaptive neuro-fuzzy inference system (ANFIS), support vector machine (SVM), and long short-term memory network (LSTM) to establish intelligent committee machine learning flood forecasting (ICML-FF) framework. The combination of these individual models achieved through simple averaging method, and further optimised using weighted averaging by K-nearest neighbour (K-NN) and genetic algorithm (GA). The effectiveness of the proposed model was evaluated using real case study for Malaysia's Kelantan River. The results show that ANFIS outperforms as individual model, while ICML-FF-based model produced better accuracy and lowest error than any one of the individuals. In general, it is found that the proposed ICML-FF is capable of robust forecasting model for flood early warning systems

Perkembangan Teknologi Informasi dan Komunikasi (TIK) telah berpengaruh terhadap berbagai aspek kehidupan manusia. Hal ini mendorong era baru peradaban manusia dari era industri ke era informasi. Berdasarkan hasil wawancara dan observasi pada TK ABA 16 Malang kami melihat masih ada guru yang beranggapan tidak menggunakan komputer dan IT (Teknologi Informasi) dalam proses pembelajaran bukan hal mengganggu jalannnya pelajaran karena guru merasa tidak mendapatkan fasilitas komputer saat mengajar, jadi inilah yang membuat guru merasa tidak perlu untuk tahu cara menggunakan komputer. Jika dilihat dari kenyataannya ini terjadi pada guru-guru yang sudah berusia tua, walaupun yang guru junior pun masih ada yang gagap pada kemajuan IT. Dari permasalahan tersebut, maka perlu diadakan kegiatan pelatihan dan pemahaman bagi guru untuk mengoptimalkan fasilitas TIK yang ada untuk menunjang keefektifan pembelajaran dan kompetensi guru. Setelah pelaksanaan pelatihan, tim pengusul akan memonitoring dan mengevaluasi pemahaman guru-guru tentang TIK yang ditentukan dengan standar keberhasilan pemahaman yaitu pencapaian skor harapan senilai 7 dari jumlah skor hasil observasi. Dari skor tersebut maka dapat disimpulkan bahwa guru sudah meningkat kompetensinya atau belum setelah mengikuti pelatihan IT mengenai penggunaan TIK sebagai media mengajar. Pelaksanaan evaluasi dilakukan dengan mengamati peningkatan kompetensi guru setelah satu minggu mengajar menggunakan IT melalui lembar observasi
