Abstract

Formaldehyde is one of the chemical products that has an important role in various industries with the percentage of global production consistently increasing over the past ten years. However, the production of formaldehyde requires considerable energy consumption. The purpose of this study is to examine other alternatives to improve energy efficiency in the formaldehyde production process. This study focuses on the reutilization of heat generated from the heat exchanger to minimize the net energy generated. The process modification was simulated using Aspen HYSYS and the net energy comparison between the original and modified process was calculated using the net-energy formula. The results show that the Net-Energy (NE) value for the original process is 18,839,836 kJ/h while for the modified process it is 4,123,000 kJ/h. This result shows that the modified process is efficient to reduce Net-Energy and can increase energy efficiency in the formaldehyde production process through the methanol dehydrogenase process.

Abstract

Indonesia merupakan salah satu negara yang rawan terjadi bencana alam. Tencatat, sepanjang tahun 2021 Indonesia telah mengalami sebanyak 5.402 frekuensi bencana yang terjadi di Indonesia menurut Badan Nasional Penanggulangan Bencana (BNPB). Penelitian ini menganalisis dan menguji efektivitas Pooling Fund Bencana (PFB) di Indonesia. Data yang digunakan dalam penelitian ini adalah data sekunder yang diperoleh melalui website Badan Pusat Statistik (BPS), Badan Nasional Penanggulangan Bencana (BNPB), Kementerian Keuangan RI yaitu data pada tahun 2016 sampai 2021 di 34 provinsi. Menggunakan data panel yang diolah menggunakan Excel dan STATA. Di tingkat pemerintah daerah, diperlukan keputusan untuk memastikan berjalannya skema pengelolaan keuangan daerah untuk bencana. Dengan memastikan hal tersebut, akan tercapai efektivitas keuangan. Hasil dari penelitian ini adalah dikarenakan alokasi anggaran dari pemerintah yang fluktuatif untuk pembiayaan bencana, maka diperlukan instrumen PFB dirancang sebagaimana mestinya yaitu untuk dimanfaatkan dalam pembiayaan kegiatan dari penanggulangan bencana dan mitigasi risiko bencana.
