Soil suction is the ability of the soil to absorb water. Type of soil in this research was peat soil and clay soil. The soil samples had been used were taken from Village III Banyu Urip, Banyuasin Regency, South Sumatera Province. Laboratory testing with Filter Paper test method. The filter paper used is Whatman Filter Paper No.42. The Scanning Electron Microscope (SEM) had been used to analyze the orientation of fiber content. Energy Dispersive Spectroscopy (EDS) also to analyze the chemical elements. Characteristics of peat soil are water content value (ω) is 294.30 %, acidity (pH) value is 3.000, and peat soils classified as fibrous peat soils. While the characteristics of clay soil are water content value is (ω) 62.05 %, acidity (pH) value is 5.000, and clay soils classified as A-7-5 (AASHTO) and OH (organic clay) based on USCS. The result of the test paper filter test on peat soil obtained from the value of suction is (Ψ) 3.2432 kPa-17.5230 kPa. The results of testing the Filter Paper test method on the clay obtained the value of suction is (Ψ) 61.8733 kPa-100.3421 kPa. The value of suction from clay soil is more than a value of suction peat soil based on Filter Paper test method.

“…Kelemahan metode analisis GC dan HPLC adalah perlakuan ekstraksi dan pemurnian di laboratorium yang membutuhkan pelarut dan waktu analisis yang lebih lama yang memungkinkan terdapatnya resiko kesalahan. Oleh karena itu, untuk mengatasi kekurangan tersebut saat ini sedang dikembangkan metode baru untuk analisis residu pestisida simazin dengan Molecular Imprinted Polymer (MIP) [5][6][7]. MIP adalah polimer sintetis dengan rongga yang spesifik untuk molekul target.…”

Molecularly Imprinted Polymer (MIP) adalah polimer sintetis dengan rongga yang spesifik untuk molekul target. Rongga (cavities) diperoleh akibat pembuangan template, dimana rongga tersebut berfungsi mengenal molekul dengan ukuran, struktur serta sifat-sifat fisika kimia yang sama dengannya. Polimer yang dihasilkan dari teknik MIP ini diterapkan pada permukaan material sensor sebagai instrumen pendeteksi dan penganalisis simazin. Keunggulan dari MIP adalah sistem sensor yang telah mampu memberikan hasil analisis suatu cemaran secara cepat, mudah dan dalam konsentrasi yang rendah (ppm). Tujuan dari penelitian ini adalah membuat MIP simazin sebagai sensor cemaran dan uji kinerja secara potensiometri. Hasil penelitian mendapatkan kondisi optimum pembuatan Molecularly Imprinted Polymer (MIP) simazin diperoleh dengan komposisi 6,02 mL kloroform; simazin 0,025 g; 0,9 mL methacrylic acid (MAA); 1,57 mL ethylene glycol methacrylic acid (EGMA); 0,07 g benzoyl peroxide (BPO) dengan waktu pemanasan selama 150 menit pada temperatur 70oC. Uji kinerja sensor dilakukan secara potensiometri dan diperoleh sensor MIP simazin yang dibuat memiliki sensitivitas dan stabilitas pada rentang konsentrasi 0,01-1,0x10-3 ppm dengan batas deteksi sebesar 0,01x10-3 ppm dan masa pakai mencapai 90 hari.Molecularly Imprinted Polymer (MIP) is a technique of polymer preparation derived from cross-linked polymers and it has cavities that are appropriate with templates.

“…Sensors are system elements that can capture and filter physical and chemical phenomena, then convert them into electrical signals in the form of electric current or voltage, generally known as electrodes. Currently, the use of electrochemical sensors in recognizing foreign objects in the surrounding environment has developed [7], [19], [20]. Related to previous research that has been done by other researchers, the novelty of this research is the method of making MIP and placing MIP on the surface of aluminum electrodes with the assumption that this material is a conductor that will facilitate ion transfer.…”

The use of pesticides and herbicides containing the active ingredient simazine must be carried out strictly so as not to cause adverse effects on humans and the environment. Measurement of contaminants in the form of simazine as one of the active ingredients of pesticides and herbicides is very important. An imprinted polymer molecule (MIP) has been made using methacrylic acid (MAA) as a functional monomer and ethylene glycol dimethyl acrylate (EGDMA) as a cross-linker. This research resulted in a molecularly imprinted membrane for the specific recognition of simazine. The electrochemical potential used with MIP coated electrodes provides both qualitative and quantitative detection of simazine. Polymer coated molecular-based potentiometric sensors (MIP) are promising analytical tools for developing highly selective analytical sensors. Optimal conditions for the production of simazine MIP were found to be 6.02 mL of chloroform, 0.025 g of simazine, 0.9 mL of MAA, 1.57 mL of EGDMA, and 0.07 g of benzoyl peroxide (BPO) with a heating time of 150 minutes at 70 o C. The results of the electrode performance test resulted in stable and unstable conditions, with a measurement range on the surface of the double-layer electrode with a coefficient distribution of 0.9897. Compared with electrochemical procedures with MIPs sensors and spectrophotometry, it produces a significant value with a 95% confidence level with Q-test results for the 0.48 ppm level with spectrometric procedures obtained Q exp = 0.25, Q crit value is 0.71.
