Bahan bakar merupakan hal essensial dalam kehidupan manusia, salah satunya adalah gas alam. Gas alam banyak digunakan di berbagai sektor seperti industri, transportasi, dan rumah tangga. Gas alam diperoleh dari proses pengeboran minyak bumi. Gas alam yang diperoleh masih mengandung gas-gas seperti karbondioksida CO2) dan hidrogen sulfida (H2S) yang perlu dihilangkan karena dapat menyebabkan korosi pipa bahkan memicu terjadinya ledakan. Hasil pembakarannya pun berbahaya bagi manusia dan lingkungan. Oleh karena itu penelitian ini dilakukan untuk menentukan nilai amine strength dan H2S loading serta hubungannya dengan pH sampel lean amine. Analisis nilai amine strength dan H2S loading dilakukan terhadap sampel lean amine, yaitu sampel yang berasal dari amine regenerator system di PT. SIPL. Penentuan nilai amine strength dilakukan dengan titrasi asidimetri dengan larutan HCl 0,5 N sebagai titran menggunakan autotitrator. Penentuan nilai H2S loading dilakukan dengan titrasi iodometri menggunakan larutan standar Na2S2O3 0,1 N. Nilai amine strength yang diperoleh dari hasil analisis selama 7 hari adalah 33,620%; 34,295%; 34,725%; 35,139%; 35,583%; 36,464% dan 36,683%. Nilai H2S loading yang diperoleh dari hasil analisis selama 7 hari yaitu, 0,0587; 0,0376; 0,0372; 0,0500; 0,0356; 0,0367 dan 0,0359 mol/mol. Semakin tinggi nilai pH sampel semakin rendah nilai H2S loading. Nilai H2S loading yang diperoleh masih dalam batas aman yang ditentukan oleh US EPA yaitu 16 ppm.

Textile waste containing dye can generate environmental problems especially for human. Therefore some techniques are developed to overcome the impact of toxic contaminant from dyes residue, one of these is the photocatalysis technique. The photocatalysis mechanism TiO2 is a popular photocatalyst and in order to improve its activity the composite formation with a some solid support are attempted. The development of TiO2 composite with a sustainable support source; bamboo leaves was conducted. The composite was prepared by dispersing titanium isopropoxide into bamboo leaves ash (BLA) followed by calcination process. Hysicochemical characterization of the photocatalyst was performed by using XRD, gas sorption analyzer and SEM-EDX analysis. By the characterization it is found that BLA contains silica in highest percentage and furthermore TiO2 in the mixed anatase and rutile phases were formed the composite.

Zeolite modification with Cu has been conducted. Material modification is done by impregnating Cu through a zeolite powder reflux process with CuSO4.5H2O solution so that theoretical Cu concentration is 5% followed by oxidation and reduction of solids. Material characterization was performed by x-ray diffraction analysis (XRD), Fourier Transform Infra-Red (FTIR) and acidity testing of Cu/Zeolite catalyst.The results showed that the crystallinity level of Cu/Zeolite did not change significantly when compared with natural zeolite. Changes occur at the intensity of the resulting peak, as at the peak of 2Î¸ 27.826 Âº which is the mordenite phase in Cu-zeolite has a peak intensity of 1360, while at zeolite with peak of 2Î¸ 27,760 Âº with the same phase meliki the smaller intensity of 1048. Testing the acidity of the catalyst was carried out by adsorbing pyridine into the catalyst, then calculating the adsorbed pyridine level, in the zeolite samples of pyridine adsorbed by 0.003 g / g while in the Cu-zeolite sample of 1.0574 g / g. The result of analysis with FTIR to show acidity level is seen in the range of wave number between 1450-1495 cm-1, from zeolite catalyst with wave number 1491,17 cm-1 peak intensity (% T) equal to 6,53, while at Cu-zeolite with wave number 1468.05 cm-1 peak intensity (% T) of 10.99. Testing of catalytic properties of Cu-zeolite catalyst on esterification reaction was done by taking acetic acid with concentration of 0.05 mol and methanol with concentration of 0.1 mol, then added 0.2 gram of catalyst, then reflux process for 1 hour. The results of reflux in the form of methyl esters were then analyzed by gas chromatography to see the retention time and the area of the resulting area. The use of Cu-zeolite catalysts yielding ester is indicated by the appearance of the ester peak.

Quantitative analysis in the integrated laboratory of Jombang District Agriculture Office has been done on two samples of organic fertilizer with phosphorus and potassium parameters, considering these two elements are macronutrients which have an important role in the growth and development of plants. Determination of phosphorus level has been done by ascorbic acid method using double beam UV-Visible spectrophotometer, while determination of potassium level has been done by flame photometric method. There are 2 samples code of organic fertilizer, 13/F/16 and 14/F/16. From the result of analysis, the phosphorus level as P2O5 in 13/F/16 sample is 0.275%, while in the 14/F/16 sample is 0.29%. The potassium level as K2O in 13/F/16 sample is 2.58%, while in the 14/F/16 sample is 2.67%. These results meet the requirements for compost quality standards based on SNI 19-7030-2004, because they exceed the minimum requirements, which are 0.10% for phosphorus level and 0.20% for potassium level.

Synthesis of aluminium pillared smectite from two raw clays, saponite and Indonesian montmorillonite, has been investigated. The clays were characterized by XRD, N2 adsorption isotherm, DTA-TGA, surface acidity measurements using pyridine-FTIR method, and evaluated for catalytic esterification reaction. The characterization indicated an increase in d001 by metal oxide pillar, increase in BET specific surface area, and surface acidity. DTA-curves showed exothermic peaks in the range of 100-130oC and 400-800oC. TGA curves showed an increase in thermal stability of pillared clays. For both kinds of clays, it was also observed that pillarization reduced weight loss at high temperature. Esterification reaction rate constant and surface acidity data showed that the Brønsted acidity dominantly affects the reaction mechanism compared with the effect of specific surface area and Lewis acid site. Montmorillonite and pillared montmorillonite exhibited higher catalytic activity than saponite and pillared saponite although the specific surface areas of the latter are higher.
