RINGKASAN

Telah dilakukan kegiatan pengabdian masyarakat mengenai pengenalan teknik pengolahan limbah anodisasi menjadi produk alum, aluminium hidroksida, dan alumina kepada masyarakat industri pelapisan logam di daerah Klayatan Malang Jawa Timur. Tujuan kegiatan ini adalah untuk menyadarkan masyarakat akan bahaya limbah anodisasi, memotivasi maasyarakat agar mau mengolah limbahnya, memberikan bekal ketrampilan pengolahan limbah, dan menjalin hubungan berkesinambungan. Kegiatan pengabdian masyarakat dibagi menjadi 3 tahap, yaitu persiapan, kegiatan penyuluhan-pelatihan, dan monitoring pasca pelatihan. Pada tahap persiapan disiapkan berbagai dokumen terkait penjaringan peserta dan evaluasi, penyiapan pameran produk dan uji kimia kualitas produk, penyiapan bahan dan alat praktek. Peserta yang terjaring 13 orang dari 30 orang yang direncanakan. Pada tahap kegiatan penyuluhan-pelatihan dilakukan penyuluhan tentang bahaya limbah anodisasi dan pelatihan pengolahan limbah. Peserta yang hadir 10 orang. Pada tahap monitoring pasca pelatihan dilakukan monitoring ke industri terkait penerapan pengolahan limbah di lapangan oleh peserta. Peserta yang hadir 14 orang. Dari kegiatan ini dapat disiumpulkan bahwa 88,85 % peserta kegiatan sadar akan bahaya limbah anodisasi bagi kesehatan, 100% masyarakat (peserta kegiatan) paham akan potensi ekonomi limbah anodisasi dan termotivasi untuk mengolah limbahnya, 100% masyarakat (peserta kegiatan) terampil mengolah limbah anodisasi menjadi produk , terutama aluminium hidroksida, dan 100% masyarakat (peserta kegiatan) bersedia menjalin hubungan yang berkesinambungan dengan akademisi terkait pengolahan limbah anodisasi.

SUMMARY The recycling technology of disposal from anodization industry to produce new products such as aluminium, aluminium hydroxide and alumina has been introduced to the people living nearby the industry, in Klayatan Malang, East Java. The whole activity was aimed to raise the awareness of the danger of the disposal to the people, to give recycling skill and to initiate a long term cooperation between the tutor and the people participants. The public service activity was performed in three steps: preparations, workshop and after workshop survey. The first step consist of the preparation of all documents related to the recruitment of participants and the evaluation forms, the preparation of products exhibition and the chemical assessment of the poducts, and the procurements of needed materials and tools. There was 13 participants engaged in this step, less than the aimed 30 persons. In the second step, the workshop, a lecture was given to 10 participants about the daanger of the wastewater released from the anodization industry. In the last step, 14 participants was performing visitation to an anodization industry to see their wastewater treatment facility. It was possible to conclude, from this activity, that 88,85% of the participants were aware of the danger of the disposal released from the anodization industry to their health, all of the participants were well-informed about the economical prospective of the awste and motivated to recycle it, all of the participants were well-trained to recover the minerals contained in the wastewater and reuse them into products, especially the aluminium and all of the participants were willing to preserve the contact with the tutor related to the recycling of wastewater
