Abstract
Perkembangan industri yang semakin pesat untuk mendukung kebutuhan hidup manusia, salah satunya dalam industri makanan yang berupa pengolahan ikan di Sentra Ikan Bulak Surabaya. Sentra Ikan Bulak Surabaya memiliki IPAL yang terdiri dari bak penampung, bak pengendap dan biofilter. Metode fotokatalisis yang digunakan dalam penelitian berfungsi untuk meringankan beban organik yang terkandung dalam air limbah sebelum dialirkan menuju unit biofilter. Selain itu, penelitian ini bertujuan untuk menentukan massa senyawa ZnO dan TiO2, waktu dan intensitas penyinaran yang optimum untuk menurunkan parameter BOD, COD dan NH4 dalam limbah cair industri hasil perikanan serta penentuan kinetika kimia.
Pada metode fotokatalisis yang menggunakan senyawa ZnO dan TiO2 memiliki massa masing-masing 1 g, 1,5 g dan 2 g. Kemudian terdapat variabel intensitas penyinaran sebesar 732±5,17 μW/cm2, 743±3,56 μW/cm2 dan 849±1,92 μW/cm2 serta variabel waktu penyinaran selama 8 jam yang dilakukan sampling pada setiap jamnya. Setelah itu akan dilakukan analisa hasil dan pembahasan yang digunakan untuk menjawab tujuan penelitian.
Proses fotokatalisis menggunakan ZnO diketahui dapat menurunkan kandungan BOD, COD dan NH4 sebesar 27%, 31% dan 35%. Sedangkan proses fotokatalisis menggunakan TiO2 diketahui dapat menurunkan kandungan BOD, COD dan NH4 sebesar 62%, 66% dan 79%. Proses fotokatalisis yang terjadi cenderung mengacu pada model kinetika kimia orde 0 yang berarti laju reaksi tidak bergantung pada konsentrasi ZnO dan TiO2.

The development of the industry is increasingly rapid to support the needs of human life, one of which is in the food industry in the form of fish processing at the Bulak Fish Center Surabaya. The Bulak Fish Center Surabaya has a WWTP consisting of a storage tank, a settling tank and a biofilter. The photocatalysis method used in the study serves to remove the organic load contained in the wastewater before it is flowed to the biofilter unit. In addition, this study aims to determine the mass of ZnO and TiO2 compounds, the optimal irradiation time and irradiation intensity to reduce the parameters of BOD, COD and NH4 in the wastewater of the fishery processing industry and also determination of chemical kinetics.
In the photocatalysis method using ZnO and TiO2 compounds, they have masses of 1 g, 1.5 g and 2 g, respectively. In addition, there are also irradiation intensity variables of 732±5,17 μW/cm2, 743±3,56 μW/cm2 and 849±1,92 μW/cm2 with irradiation time variables of 8 hours which were sampled at each hour. After that, the results will be analyzed and discussed to answer the research objectives.
The photocatalysis process using ZnO is known to reduce BOD, COD and NH4 by 27%, 31% and 35%. Meanwhile, the photocatalysis process using TiO2 is known to reduce BOD, COD and NH4 by 62%, 66% and 79%. The photocatalysis process that occurs tends to refer to the zero-order chemical kinetics model, which means that the reaction rate does not depend on the concentration of ZnO and TiO2.
