Abstract

A method for determination of carbofuran pesticides residue utilizing extraction by sonication has been developed for spike soil sample collected from horticulture farms in Lembang, North Bandung Regency, Indonesia. The simple, reliable, and cost-effective method was performed without any clean up prior injection to HPLC-UV. The method was validated by evaluating its detection limit, linearity, repeatability, recovery, and matrix effect. The detection limit of the method is 0.50 mg/kg. The linearity of the method is very good (r=0.99677) for concentration range of 1.0 to 5.0 mg/kg. The repeatability of the method is acceptable (CV value of 2.56 %). The fortified recoveries are acceptable, ranging from 93.44 to 101.03%. Statistical analysis shows that the matrix effect is insignificant to the method. The application of the method is able to offer a minimization of waste, miniaturization of method, and increased the safety for the operator as required for Green Analytical Chemistry.

Abstract

EFEKTIVITAS BIOKOAGULAN Vicia faba DALAM MEMPERBAIKI LIMBAH CAIR PULP DAN KERTAS ABSTRAK Telah dilakukan penelitian mengenai efektivitas kacang babi Vicia faba sebagai biokoagulan dalam memperbaiki sifat fisik dan kimiawi limbah cair industri pulp dan kertas. Penelitian ini bertujuan untuk mengetahui kemampuan dan konsentrasi Vicia faba yang optimum dalam memperbaiki sifat fisik kimiawi limbah cair industri pulp dan kertas. Sifat fisik dan kimia yang diteliti mencakup turbiditas, total padatan tersuspensi (TSS) limbah, kandungan kesadahan dan Chemical Oxygen Demand (COD) limbah. Rancangan penelitian yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL), dengan lima taraf konsentrasi yaitu 0,02%; 0,04%; 0,06%; 0,08% dan 0,1% (v/v) masing-masing dengan lima kali pengulangan. Hasil penelitian menunjukkan bahwa konsentrasi suspensi Vicia faba sebanyak 0,1% mampu menurunkan turbiditas limbah hingga mencapai 98,5% dan TSS limbah hingga mencapai 74,8%. Untuk parameter kimiawi, pada konsentrasi tersebut mampu menurunkan kesadahan limbah hingga 41,6%, dan kandungan COD limbah mencapai 60,6%. Kata kunci : Vicia faba, biokoagulan, limbah cair industri pulp dan kertas EFECTIVITY OF Vicia faba AS BIOCOAGULANT FOR PULP AND PAPER WASTE WATER ABSTRACT The Study about Efectivity of broad bean (Vicia faba) as a biocoagulant for pulp and paper mill waste water were conducted. Coagulation-flocculation is an important process in wastewater treatment that are used to remove colloid and suspended particles. The objective of this research was to determine the ability and the optimum concentration of Vicia faba. The observed  parameters during this research were Turbidity, Total Suspended Solid, Total Hardness and Chemical Oxygen Demand. The study was conducted using Randomize Complete Design with five replications and five level concentrations (0,02%; 0,04%; 0,06%; 0,08%; 0,1%). The data show  that the optimum concentration of Vicia faba was around 0,1%. Vicia faba at concentration 0,1% effectively removes turbidity over 98,5%, 74,8%, for Total Suspended Solid, 60,6% of Chemical Oxygen Demand and 41,6% for total hardness. Keywords: Vicia faba, biocoagulant, pulp and paper mill waste water

Abstract

Severe river pollution creates a stressful environment for aquatic organisms, causing disturbances to their health and leading to their extinction. Thus, in this study, the stress responses of tolerant (Oreochromis niloticus) and sensitive (Cyprinus carpio) fish to river pollution in the Citarum River, Indonesia were investigated. The two groups of fish were exposed to varying levels and lengths of water pollution, their blood was sampled, and stress responses were identified. The red blood cells (RBC) count, haemoglobin (HGB), haematocrit (HCT), white blood cells (WBC) count, blood glucose levels, and derived haematological indices such as mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC), were measured. Significant changes in these indices, with tendential changes in RBC and HCT, were observed, indicating that stress responses had occurred in both groups of fish. The sensitive fish recorded more pronounced changes in their haematological activities, with greater amounts of blood parameters being altered in response to water pollution exposure. This result suggested that the sensitive fish were more susceptible to environmental stressors and were, therefore, more vulnerable to extinction in a polluted natural environment.
