PENURUNAN TIMBAL PADA AIR LIMBAH  INDUSTRI BATIK MENGGUNAKAN ARANG BIJI SALAK DENGAN BERBAGAI VARIASI MASSA DAN WAKTU KONTAK 
Ridha Auliya Haq1, Saudin yuniarno2, Suparmin3

Latar Belakang: Kadar timbal (Pb) pada air limbah batik perlu diturunkan untuk menghindari dampak buruk pada lingkungan dan kesehatan masyarakat. Pengolahan menggunakan biosorben mampu menurunkan kadar Pb pada air dengan beberapa variasi, salah satunya menggunakan arang biji salak. Tujuan penelitian ini mengetahui efektifitas arang biji salak dengan variasi massa dan waktu kontak dalam menurunkan kadar Pb air limbah batik.

Metodologi: Penelitian quasi eksperimen ini menggunakan dengan rancangan acak lengkap (RAL). Sampel penelitian diambil dari salah satu industri dengan air limbah batik lebih dari 0,1 mg/l. Penelitian ini terdapat 10 variasi perlakuan pemberian arang biji salak yaitu waktu 30, 60 dan 90 menit dengan massa 0.6, 0.8 dan 1gram yang dikombinasikan serta kontrol.

Hasil Penelitian: Hasil menunjukan efektifitas penurunan Pb air limbah batik yang berbeda pada perlakuan dibandingkan dengan kontrol, yaitu pada waktu 30 menit massa 0,6 gram 85.226%; waktu 30 menit massa 0,8 gram 85.942%; waktu 30 menit massa 1gram 87.15%; waktu 60 menit massa 0,6 gram 90.572%; Waktu 60 menit massa 0,8 gram 89.373%; waktu 60 menit massa 1 gram 92.753%; waktu 90 menit massa 0,6 gram 88.405%; waktu 90 menit massa 0,8 gram 88.405%; waktu 90 menit massa 1 gram 89.09%.

Kesimpulan: Penambahan arang biji salak mampu mengurangi kadar Pb dengan efektifitas tertinggi adalah 92,753% pada perlakuan waktu 60 menit massa 1 gram.

ABSTRACT

REDUCTION OF Pb CONTENT IN WATER WASTE OF BATIK INDUSTRY USING CHARCOAL OF SALAK SEED WITH MASS AND CONTACT TIME VARIATION
Ridha Auliya Haq1, Saudin yuniarno2, Suparmin3

Background: lead (Pb) levels in batik waste water needs to be lowered to prevent the cause of enviroment damage and public health. Processing using biosorbent can reduse Pb level in water with some variation, one of them using charcoal of salak seed. This research aimed at identifying the effectivity of charcoal of salak seed with mass and contact time variation in reduce Pb content obatik waste water.

Methodology: this was a quasi experimental study with a completely randomized design (CRD). Sample of this reseach was taken from one industry with batik wastewater over 0.1 mg / l. There were 10 variations treatment from charcoal of salak seed. There are 30, 60 and 90 minutes for contact time. 0.6, 0.8 and 1gram for mass and control.

Results: There were any differences in the effectivity of each treatment, compare to control in decreasing the Pb levels in batik waste water. At time 30 minutes  mass 0.6 g was 85.226%; time 30 minutes mass 0.8 g was 85.942%; time 30 minutes mass 1 g was 87.15%; time 60 minutes mass 0.6 g was 90.572%; time 60 minutes mass 0.8 g was 89.373%; time 60 minutes mass 1 g was 92.753%; time 90 minutes mass 0.6 g was 88.405%; time 90 minutes mass 0.8gram was 88.405%; time 90 minutes mass 1 g was 89.09%.

Conclusion: The addition charcoal of salak seed can reduce Pb level with the most effective was 92,753% at treatment time 60 minutes mass 1 g.

Keywords: Heavy Metal, Pb, Charcoal Salak Seed.
