Indonesian Journal of Fundamental and Applied Chemistry (IJFAC) is an international research journal and invites contributions of original research articles as well as review articles in several areas of chemistry. The journal aims to publish refereed, high-quality research papers with significant novelty and short communications in all branches of chemistry. Papers which describe novel theory and its application to practice are welcome, as are those which illustrate the transfer of techniques from other disciplines. IJFAC calls for papers that cover the following fields: Biochemistry Inorganic chemistry Physical chemistry Organic chemistry Analytical chemistry Applied Chemistry All papers are peer reviewed by at least two referees. Papers presented at conferences are peer reviewed and selected with the same standards as individually submitted papers. They therefore have the same archival value. Article should be submitted by the Online Submission Module at www.ijfac.unsri.ac.id or email to ijfac@unsri.ac.id

Abstract

Contamination by organic matters, nutrient, pathogenic bacteria, micro pollutant and detergent/surfactant caused quality decrease of water in tidal zone. This study was aimed to evaluate quality of various water resources and to elaborate correlation between tidal environment condition and water resources quality at Muliasari village district of Tanjung Lago. Water sample was taken by purposive sampling method. Analysis result using Storet method showed average value of several parameters at high tide are: temperature 31.37°C;TSS 74.28 mg/L;pH 3.38; salinity 1.82; DO 5.05 mg/L; BOD 32.51 mg/L; COD 98.5 mg/L; ammonia 0.29 mg/L; phosphate 0.1690 mg/L; Fe 0.272 mg/L and Coliform 0.31/100 mg/L. At low tide these parameters had values for temperature 27.13°C; TSS 67.14 mg/L; pH 3.38; salinity 1.7; DO 4.86 mg/L; BOD 14.13 mg/L; COD 43.71; ammonia 0.244 mg/L; phosphate 0.1695 mg/L; Fe 0.232 mg/L and Coliform 0.32/100 mg/L. According to Governor’s provision no.16/2005 on water quality standard, water from various resources of Muliasari village were moderately polluted. Domestic waste water management is needed at this area followed by training and enhance occupant’s awareness to maintain hygiene and environment quality. Monitoring effort is also necessary on water resources quality for at least once every 6 months. Key words: Water quality, tidal zone, domestic waste

Abstract

Anthracite and Sub-bituminous as activated carbon raw material had been utilized especially in mining field as adsorbent of dangerous heavy metal compound resulted in mining activity. Carbon from coal was activated physically and chemically in various temperature and particle sizes. Characterization was carried out in order to determine the adsorbent specification produced hence can be used and applied accordingly. Proximate and ultimate analysis concluded anthracite has fixed carbon 88.91% while sub-bituminous 49.05%. NaOH was used in chemical activation while heated at 400-500°C whereas physical activation was conducted at 800-1000°C. Activated carbon has high activity in adsorbing indicated by high iodine number resulted from analysis. SEM-EDS result confirmed that activated carbon made from coal has the quality in accordance to SNI and can be used as adsorbent in acid water treatment.

Abstract

It has been investigated of the laboratory effluent treatment using coagulant Alum sulphate (AS) and Poly Aluminum Chloride (PAC). This research purposes to get the best doses of coagulant in waste water treatment. Parameter focuses are Total Dissolved Solid (TDS), Fe, Mn, Cr, and Ammoniac (NH3). The result shows the Alum sulphate was more effective. The effectiveness of pollutant decrease is 58,80% of TDS, 99,14% of Fe, 98% of Cr, 77,24% of Mn, and 23,18% of Ammoniac, respectively.Keywords: Laboratory wastewater, Alum sulphate, Poly Aluminum Chloride, Heavy metals, Coagulation

Abstract

Study of igneous rocks derived from Ogowele Village and Village Toli-Toli Bajugan has been conducted to determine the magnetic minerals contained in the igneous rocks, as well as determine the crystal system, lattice constants and field diffraction by comparison sieve 60 mesh and 80 mesh. Process characterization and analysis using X-Ray Diffraction (XRD). Characterization and analysis of the results showed that the compound was detected both rock samples Fe3O4, SiO2, Al2O3 and MnO2. Igneous rocks derived from Ogowele village is dominated by compounds SiO2 (quartz) by 52% and rocks from Bajugan village dominated by the compound Fe3O4 (magnetite) by 40%. The crystal structure is cubic and hexagonal compound to compound Fe3O4 SiO2. Fe3O4compound cubic lattice constants are a = b = c is 8.375 Å. To compound the hexagonal SiO2 ie a = b of 4.898 Å and c of 5.385 Å. Field diffraction on Fe3O4compound is (3 1 1) and the SiO2 compound that is (1 0 1).Keywords: X-Ray Diffraction, Fe3O4 Compound, SiO2 Compound, cubic, hexagonal

Abstract

Research had been carried out on tidal marshes condition at tertiary channel Muliasari Village and the effect of land user behavior on water and soils quality. The aimed of research is to evaluate water and soil quality and potent pollution due to fertilizer and pesticide utilization. The research methods are survey and qualitative approach using observation and directed interview with questionnaire aid. Water and soils samples were taken by purposive sampling method. Measurement obtained soils has pH 4.59 and 3.92 for TC4 and TC5 respectively. Cation exchange capacity is 21.65 mg/100 g or TC4 and 20.62 mg/100 g for TC5. C-organic contained in both TC4 and TC5 are very high whereas Total-N is moderate hence ratio C/N has moderate value. P2O5 detected as 81.55 ppm at TC4 and 36.06 ppm at TC5. According to Soils Research Centre Bogor, TC4 and TC5 has moderate value of N (35%) while P and K very high (81.55 ppm and 103.32 ppm). Scoring result concluded that soils is in good health and has 76% (TC4) and 73% (TC5). Storet method confirmed score result for soils as B-class or in good condition. According to these result, TC4 and TC5 of Muliasari Village was lightly polluted and still has good prospect as crops land. Key Words: Tidal zone, Water quality, pollution
