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

Air limbah industri bakery memiliki karakteristik kandungan organik, lemak, dan surfaktan yang tinggi. Keberadaan surfaktan pada air limbah dapat mengganggu proses degradasi kandungan organik dan lemak pada instalasi pengolahan air limbah khususnya pengolahan secara biologis/lumpur aktif. Studi ini membahas tentang performa integrasi system stripper-lumpur aktif yang diaplikasikan untuk mengolah air limbah industry bakery dalam skala full scale. Proses stripper dilakukan dengan menggunakan kolom yang diintegrasikan dengan bak aerasi pada kisaran HRT (waktu tinggal) 24 jam. Proses stripper memberikan efisiensi enurunan COD dan surfaktan tertinggi sebesar 96% dan 80%. Proses lumpur aktif digunakan untuk mengolah keluaran dari proses stripper dengan karakteristik lumpur aktif MLSS 4000-4500 mg/L, FM/ rasio 0,268, sludge age 11 hari dan HRT 24 jam, proses degradasi dengan lumpur aktif ini mampu memberikan efisiensi penurunan COD dan surfaktan sebesar 79% dan 88%. Hasil penelitian menunjukkan bahwa unit IPAL dengan menggunakan sistem stripper-lumpur aktif memiliki efisiensi penurunan COD, TSS, dan BOD sebesar 98,9%, 87,9%, dan 96,4%, sehingga sistem ini merupakan teknologi yang tepat untuk diterapkan pada pengolahan limbah industri bakery.

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.
