Abstract

Indonesia telah menandatangani kesepakatan internasional Kyoto Protocol dalam upaya turut serta berkontribusi dalam mitigasi pemanasan global. Melalui dokumen Nationally Determined Contribution (NDC) Indonesia berkomitmen untuk menurunkan emisi karbon sebesar 29% pada tahun 2030 secara mandiri atau sebesar 41% bila mendapat dukungan internasional. Fotobioreaktor merupakan sistem yang dapat diterapkan dalam upaya menahan  jumlah karbon dioksida yang dilepas melalui cerobong industri ke udara. Dengan mengumpankan gas karbondioksida yang diemisikan oleh cerobong ke dalam sistem fotobioreaktor di mana mikroalga ditumbuhkan maka alih-alih gas karbon dioksida di lepas ke udara dapat digunakan sebagai sumber karbon bagi mikroalga untuk bertumbuh dan berkembang. Penerapan teknologi fotobioreaktor dapat meningkatkan citra perusahaan sebagai Perusahaan Hijau yang memberikan daya ungkit selain kinerja lingkungan perusahaan juga potensi mendapatkan insentif ekonomi melalui Mekanisme Pembangunan Bersih. Meski demikian masih terdapat tantangan besar dalam penerapan fotobioreaktor mikroalga untuk mitigasi emisi karbon dioksida. Selain kendala dalam teknik pemanenan mikroalga juga keterbatasan laju serapan karbon dioksida oleh mikroalga. Kata kunci : fotobioreaktor, perusahaan hijau, mikroalga, karbon dioksida

Abstract

Pangkalan Susu Coal Fire Steam Power Plants (CFSPP) are planned to build in Tanjung Pasir Village, Langkat Regency taking sea water as cooling condenser of power plants, and through it back into the sea. To explore the possibilities of re-entry of the circulation of hot water to the intake, it is necessary to study the termal dispersion within the framework of those plans. In this study, numerical modeling to determine termal distribution pattern that comes out from CFSPP outlet. From the study it could be concluded that with the given intake inlet ? discharge outfall design configuration and under the worst scenario, cooling water system of Pangkalan Susu unit 3 4 is safe i.e. re-circulation of warmcooling water will not happen. The Pangkalan Susu unit 3 4 will consume intact sea water (30.5oC). However, the Pangkalan Susu unit 1 2 will be influenced by the warm cooling system that may decrease its cooling system efficiency since its inlet is covered by shattered sea water (31.2oC ? 32.2oC).keywords : thermal dispersion, power plant. numerical modeling

Abstract

Ikan nila (Nile tilapia) Oreochromis niloticus adalah spesies ikan air tawar asal Afrika yang saat ini telah dibudidayakan di lebih 100 negara di dunia. Tahun 2004 produksinya hanya mencapai 97.116 ton, tetapi pada tahun 2009 produksinya dapat mencapai 378.300 ton atau terjadi peningkatan sebesar 289%. Mudahnya ikan nila berkembang biak menyebabkan ikan ini menjadi prioritas untuk pengembangan usaha dan industri budidaya ikan dan dikenal dengan julukan aquatic chicken atau ikan yang dapat dikembangkan seperti industri ternak ayam. Tujuan dari perekayasaan dan pengembangan ikan nila SALINA adalah untuk menghasilkan benih hibrida ikan nila SALINA toleran salinitas tinggi untuk mendukung pengembangan usaha budidaya perikanan, peningkatan produksi dan pemanfaatan lahan tambak idle yang luasnya mencapai 60 % dari 1,4 juta lahan tambak idle yang terbengkalai tidak termanfaatkan akibat kerusakan lingkungan dari program intensifikasi budidaya udang pada periode tahun 1980 an. kata kunci : rekayasa produksi ikan nila salina, perairan payau, wilayah pesisir
