Anggraeni, Eka Tiyas (2019) Analisis Energi Dan Aliran Pada Reverse Electrodialysis Menggunakan Elektroda Karbon Dari Perbedaan Gradien Salinitas Air Laut Dan Air Sungai. Sarjana thesis, Universitas Brawijaya.
Abstract
Konsumsi energi sangat bergantung pada bahan bakar tak terbarukan yang diperkirakan energi yang konsumsi 25.5 TW pada tahun 2040 dan akan terus meningkat. Salah satu potensi energi terbarukan adalah Salinity Gradien Power (SGP), dengan memanfaatkan energi bebas Gibbs yang dihasilkan dari campuran gradient keasinan pada air laut di pantai. Potensi kelistrikan perairan ini di Indonesia mencapai 727.000 MW. SGP terbagi menjadi 2 metode yaitu; Pressure-Retarded Osmosis (PRO) dan Reverse Electrodialysis (RED). RED menggunakan sistem pemanenan energi SGP dimana untuk memanen energi digunakan cation exchange membran (CEM) yang bermuatan negatif dan anion exchange membran (AEM) bermuatan positif. Pada percobaan ini digunakan Rancangan Acak Kelompok (RAK) yang disusun dengan 2 faktor yaitu konfigurasi (konfigurasi I, II, III, dan IV) dan kecepatan aliran (8, 14, dan 19 cc/s), dimana perlakuan dilakukan dalam waktu 20 detik yang diulang 3 kali. Berdasarkan hasil penelitian, didapatkan bahwa kecepatan air laut dan sungai sintesis berpengaruh sangat nyata terhadap open circuit voltage (OCV), resistance, dan gross power density (GPD). Hasil rata-rata OCV dan GPD tertinggi didapatkan pada kecepatan aliran 19 cc/s dan pada konfigurasi IV (counter-current flow schematic), yaitu sebesar 184.85 mV dan 0.1480 W/cm2. Hasil rata-rata resistance tertinggi didapatkan pada kecepatan aliran 8 cc/s dan pada konfigurasi I, yaitu sebesar 2750.3169 Ω/cm2. Efisiensi energi RED adalah sebesar 11.125%.
English Abstract
Energy consumption depends heavily on non-renewable fuels which are estimated to consume 25.5 TW of energy in 2040 and will continue to increase. One potential for renewable energy is to use Salinity Gradient Power (SGP), using Gibbs free energy generated from the mixture of salinity gradient in seawater on the beach. The potential of this water electricity in Indonesia reaches 727,000 MW. SGP is divided into 2 methods including; PressureRetarded Osmosis (PRO) and Reverse Electrodialysis (RED). RED uses the SGP energy harvesting system where cation exchange membranes (CEM) are negatively charged and the positively charged membrane anion exchange (AEM). The experimental design used was Randomized Block Design (RBD) arranged in factorial with 2 factors, there are configuration (configuration I, II, III, and IV) and factor II flow velocity (8, 14, and 19 cc/s) and each treatment was carried out within 20 seconds and repeated 3 times. Based on the results of the study, it was found that the speed of seawater and rivers had a very significant effect on open circuit voltage (OCV), resistance, and gross power density (GPD). The highest OCV and GPD results were obtained at flow rates of 19 cc/s and at configuration IV (counter-current flow schematic), which is 184.85 mV and 0.1480 W/cm2. The highest average resistance results obtained at a flow rate of 8 cc/s and at configuration I, which is equal to 2750,3169 Ω/cm2. Energy efficiency of RED is 11,125%.
