Abstract

Crumb rubber is one of Indonesia’s agroindustry export commodities. This industry faces environmental problems due to their wastes, both liquid and air. The source of air pollution is commonly from drying process that emitted odor from its evaporation and heating phenomena. Industry uses wet scrubber technology as air pollution control from emitted odor from drying process. Preliminary identification in noncontrolled wet scrubber shown that wet scrubber efficiency around 47%. Low efficiency wet scrubbing process causes rain drop of water vapor around drying process. This research used electrochemical based sensor MICS 5524 as ammonia monitoring instrument, assisted with arduino as microcontroller to regulate water discharge through valve controlling scrubbing process. This electrochemical based sensor reads ammonia based on voltage reads by Arduino microcontroller. Ammonia reading then control scrubbing process by adjusting valve opening for spray water distribution. Wet scrubber efficiency increases to 66,96% due to water scrubbing control, also can save water utilization as high as 61,90%, followed by absence of rain drop contains ammonia around drying process area.

Abstract

Teknologi wetscrubber sebagai pengendali cemaran udara terutama partikulat telah banyak digunakan pada berbagai peralatan proses di industri. Umumnya, kondisi wetscrubber pada industri kecil dan menengah tidak dilengkapi dengan unit kontrol air proses, sehingga terjadi in-efisiensi penggunaan air proses yang berakibat pada cemaran air yang dibuang ke badan lingkungan. Dirancang sebuah kegiatan penelitian dengan mengacu pada; modifikasi mekanisme penyerapan cemaran partikulat emisi, dengan mereview data analisis cemaran partikulat di industri pada pengendalian partikulat tanpa kontrol penggunaan air proses; penerapan kontrol proses berbasis mikrokontroller pada operasional penggunaan air proses digunakan untuk mengetahui kinerja penghematan air proses sebagai spray water. Beban partikulat divariasi sebagai tiga tingkatan beban partikulat dan digunakan sebagai penentu efisiensi pengikatan terhadap beban partikulat. Hasil ujicoba peralatan dengan perangkat kontrol yang dilakukan dalam dua variasi formulasi proses yaitu 100-300-600 dan 200-400-600, meskipun tidak menunjukkan perbedaan nyata efisiensi antar kedua formulasi tersebut mampu meningkatkan efisiensi penghematan air proses rata - rata sebesar 59,8% dengan kata lain, mampu mengurangi cemaran ke badan lingkungan sebesar 32,3 liter/jam. Simulasi pembebanan partikulat dilakukan dengan wetscrubber dengan sampel partikel berdiameter < 2,5 µm dan laju partikulat 1 m/detik.

Abstract

Dry Rubber Content (DRC) describes a rubber particle percentage in natural rubber latex. In this paper, the relation between forward light scattering profiles of natural latex and rubber contents is reported for dry rubber content latex. The profile, characterized by Full Width at Half Maximum (FWHM), is increasing linearly with respect to rubber content. The measurement was performed immediately after latex being tapped with necessary addition of acetic acid. This addition was meant to prevent latex coagulation. There is a high linear correlation between DRC and FWHM of both domain: one and two dimension. This is indicated by correlation factor which are higher than 0.9 for both of domains and sufficient in DRC determination.

Abstract

Laju pertumbuhan industri, transportasi dan aktivitas domestik menyebabkan konsumsi hidrokarbon secara global sebagai bakar mengalami kenaikan tiap tahun. Diperkirakan konsumsi hidrokarbon global di tahun 2019 mencapai 96 juta barel per hari. Hidrokarbon yang dipersyaratkan dalam Peraturan Pemerintah No. 41/1999 tentang Pengendalian Pencemaran Udara adalah sebagai NMHC (Non Methane Hidrocarbon). Konsentrasi NMHC lebih ditujukan untuk membatasi fungsinya sebagai senyawa prekursor ozon. Badan Lingkungan Hidup (BLH) Provinsi Jawa Tengah selama 3 tahun terakhir telah melaksanakan pemantauan rutin udara ambien di 35 kota dan kabupaten di Jawa Tengah. Inventori NMHC ini untuk melihat korelasi pencemar dengan sumber penghasil emisi yang dibedakan atas lokasi yang mewakili pemukiman, industri dan lalu lintas. Hasil analisis menunjukkan paparan konsentrasi NMHC di industri, mempunyai kecenderungan lebih tinggi dibandingkan NMHC di wilayah pemukiman maupun padat lalu lintas.

Abstract

Penentuan konsentrasi partikulat pada teknologi wetscrubber umumnya menggunakan prinsip light scattering. Kesamaan prinsip kerja dengan low cost particulate sensor membuka peluang pemanfaatan low cost particulate sensor sebagai unit pengukur konsentrasi partikulat dalam modifikasi proses teknologi wetscrubber. Low cost particulate sensor yang digunakan adalah SHARP GP2Y1010 dikorelasikan dengan Sensydine Nephelometer sebagai referensi. Laju partikulat yang melalui kedua peralatan tersebut disimulasikan dari hasil pembakaran obat nyamuk, dengan periode pengambilan data selama 6-7 jam. Data hasil pembacaan SHARP GP2Y1010 dianalisis secara least square fitting dan dikorelasi linier terhadap Sensydine Nephelometer dengan hasil R2 cukup tinggi mencapai 0,88 dan pola pembacaan partikulat yang identik secara grafik.

Abstract

The coal used as a primary fuel in an Indonesian power plant produces sulfur dioxide emission from its burning process. Several testing and monitoring methods developed, from laboratory analysis, CEMs based instrument, and absorption spectroscopy method developed for this purpose. Differential Optical Absorption Spectroscopy (DOAS) method based on Lambert-Beer law used as emission quantification. DOAS instrumentation developed in this research to measure sulfur dioxide as one of the emission parameters. Sulfur dioxide generated from the reaction between the sulfuric acid and dilute sodium sulfite. CCD spectrometer used to measure sulfur dioxide spectrum intensity at 260 to 350 nm absorption cross-section. There is a high correlation between sulfur dioxide gas produced by that reaction to spectrum intensity, with coefficient determination (r2) 0.9783, 0.9822, 0.9866, 0.9928 or coefficient correlation (r) 0.989, 0.991, 0.993, and 0.996 from lowest range concentration to highest range concentration. Precision analysis from gas calibration standard using Horwitz ratio indicates instrument setup precise enough with 0.504 Horwitz ratio, according to its acceptable range. The suspended particulate matter may interfere with UV penetration into CCD detector in emission simulation test using gasoline generator exhaust that causes 2.5 times deviation error between typical 800 ppm concentrated sulfur dioxide from chemical reaction and gasoline generator exhaust.
