Abstract

Minyak kelapa sawit memegang peranan penting dalam perdagangan dunia. Standar kualitas adalah merupakan hal yang penting untuk menentukan minyak yang mempunyai kualitas yang bermutu baik. Syarat mutu diukur berdasarkan spesifikasi yang meliputi kadar ALB, air, dan zat pengotor. Tujuan penelitian ini adalah mengetahui nilai kadar air, kadar kotoran dan asam lemak bebas (ALB) yang terkandung dalam inti kelapa sawit. Penelitian dilaksanakan di Laboratorium Analisis Kimia PTPN 1 PKS Tanjung Seumentoh, yang terletak di Tanjung Seumentoh, Kabupaten Aceh Tamiang, Provinsi Aceh. Sampel yang digunakan adalah kernel atau inti sawit. Analisa kadar asam lemak bebas dilakukan dengan metode titrasi asam basa menggunakan larutan standar KOH dan indikator Tymol blue, metode oven untuk analisa kadar air, dan untuk analisa kadar kotoran menggunakan metode winnowing atau dipilih dengan tangan. Dari hasil penelitian yang dilakukan, maka dapat diperoleh Kadar kotoran rata-rata pada kernel yakni 0,053 %, kadar air rata-rata pada kernel yakni 0,354 %, kadar asam lemak bebas rata-rata pada PKO yakni 2,293 %. Hasil analisa menunjukkan bahwa mutu kernel palm di PT. Perkebunan Nusantara-1 unit PKS Tanjung Seumantoh, Aceh Tamiang kadar kotoran, kadar air pada kernel dan kadar asam lemak bebas tersebut berada telah sesuai standar yang telah ditetapkan SNI 01-0002-1987.

Abstract

Pollution of dug well water in Gampong Jawa Banda Aceh is caused by an imbalance in the ecosystem of organic and inorganic pollutants. The purpose of this study was to determine the effect of chitosan biocoagulant as a dug-well water purifier. The stages of this research were making chitosan from shrimp shells, making chitosan biocoagulant with the addition of 1% CH3COOH, and coagulation and flocculation with various biocoagulants (0.1%, 0.2%, and 0.5%) using the jar test method with fast stirring at 150 rpm and slow stirring at 50 rpm. The results of FTIR research on chitosan were characterized by the loss of the C=O group in the deacetylation process to change the acetyl amino group in chitin to amino, with a degree of deacetylation of 93.27%. The optimum performance of biocoagulants at a concentration of 0.5% can reduce pH from 7.1 to 6.9, the turbidity level to 99.99% (NTU), and E. coli to 0 jml/mL. The conclusion from this study is that chitosan biocoagulants are able to reduce turbidity levels (NTU), pH, and Escherichia coli bacteria.

Abstract

High COD levels in abattoir wastewater might cause negative impact to the environment, hence it must be lowered before being discharged into the environment. The seeds of moringa plant (Moringa oleifera) contains quite high levels of protein compounds, makes it potential as biocoagulant in coagulation-flocculation process for wastewater treatment. The objective of this research is to discover the potential of biocoagulant from moringa seeds powder in decreasing COD levels on abattoir waste water treatment. The research was performed with biocoagulant dose variations 0 g; 0.5 g; 1 g; 1.5 g; 2 g; and 2.5 g, utilizing rapid mixing at 120 rpm, and slow mixing at 30 rpm with duration 2 and 30 minutes respectively. The result showing that the optimum dose obtained at 2 g, with percentage of decreation by 93.97%. Based on the research, it is concluded that the biocoagulant derived from moringa seeds can perform effectively in COD removal of abattoir wastewater treatment.
