POTENSI KITOSAN DARI LIMBAH CANGKANG UDANG Penaeus monodon ASAL BINTUNI SEBAGAI BIOSORBEN LIMBAH ORGANIK DAN LOGAM BERAT PADA LIMBAH CAIR PLTD MANOKWARI

Abstract

The purpose of this research is to study the potency of chitosan synthesis of shrimp shells from Bintuni as a biosorbent of organic compound and heavy metal compound. The main procedure of chitosan synthesis is completed by insulating chitin from shrimp shells and then chitin is deacetilated to transform chitin to be chitosan. The wastewater were characterized to know the concentration of Total Organic Carbon (TOC), fat oil, and Zinc metal and studied the adsorption of each compound at 0,1; 0,5; 1; 2g dosage chitosan. Adsorption study result showed that chitosan can adsorb the fuel oil and Zinc metal which contained in wastewater. However, it was not adsorb the TOC compound. The yield of chitosan is 46,88%. Increasing the chitosan by up to 2 g resulted in the creasing of the adsorption effectiveness up to 99,09% for the fuel oil and 69,28% for Zinc. The maximum chitosan adsorption capacity accomplished at 0,1gram chitosan in 100 mL wastewater.

Pelatihan Pembuatan Serta Pemanfaatan Pupuk Cair Organik Dan Ecoenzym Dari Limbah Sayuran Di Simatohir

“…Pupuk organik cair yaitu pupuk yang dapat memberikan hara yang sesuai dengan kebutuhan tanaman pada tanah, karena bentuknya yang cair, maka jika terjadi kelebihan kapasitas pupuk pada tanah maka dengan sendirinya tanaman akan mudah mengatur penyerapan komposisi pupuk yang dibutuhkan. Pupuk cair organik dalam pemupukan jelas lebih merata, tidak akan terjadi penumpukan konsentrasi pupuk di satu tempat (Rumaropen et al, 2019).…”

Methyl Orange Absorption Using Chitosan from Shrimp Skin as an Adsorbent

“…Amongst the use of shrimp shells is its application as chitosan raw material for the biosorbent role. Shrimp shell-based chitosan as a biosorbent has been examined for heavy metals and organic waste treatment from the environment [13]. Shrimp shell was used as chitosan raw material in adsorbing copper [14].…”
