Abstract

Pemanfaatan limbah puntung rokok dan daun kelor sebagai biopestisida merupakan inovasi ramah lingkungan untuk mengurangi dampak negatif pestisida kimia. Limbah puntung rokok yang mengandung senyawa seperti nikotin dan alkaloid potensial sebagai pengendali hama alami. Daun kelor yang kaya alkaloid dan polifenol juga meningkatkan efektivitas biopestisida dalam menghambat hama dan meningkatkan pertumbuhan tanaman. Kegiatan pengabdian ini dilaksanakan di Desa Pulau Semambu, Kabupaten Ogan Ilir, Sumatera Selatan dengan metode studi lapangan, pelatihan masyarakat, pembuatan, serta aplikasi langsung biopestisida pada tanaman yang terdampak hama. Pengujian menunjukkan bahwa biopestisida dari limbah puntung rokok dan daun kelor mampu membasmi hingga 100% populasi hama jangkrik dalam waktu 10 menit, tanpa menimbulkan kerusakan pada tanaman hias. Sosialisasi dan pelatihan melibatkan ± 30 warga, dimana 100% responden menyatakan tertarik mencoba membuat biopestisida sendiri di rumah. Oleh karena itu, program ini direncanakan untuk dikembangkan lebih lanjut melalui pendampingan berkala dan penyediaan panduan praktis bekerjasama dengan Karang Taruna Desa Pulau Semambu agar masyarakat dapat melakukan pembuatan biopestisida secara mandiri. Hal ini sesuai dengan 97% masyarakat menyatakan terbuka terhadap kegiatan pengabdian sejenis selanjutnya. The utilization of cigarette butts and Moringa leaves as biopesticides is an environmentally friendly innovation to reduce the negative impact of chemical pesticides. Cigarette butts containing compounds such as nicotine and alkaloids have potential as natural pest control. Moringa leaves, which are rich in alkaloids and polyphenols, also increase the effectiveness of biopesticides in inhibiting pests and increasing plant growth. This community service activity was carried out in Desa Pulau Semambu, Ogan Ilir Regency, South Sumatra with field study methods, community training, making, and direct application of biopesticides on plants affected by pests. Tests showed that biopesticides from cigarette butt waste and moringa leaves were able to eradicate up to 100% of the cricket’s pest population within 10 minutes, without causing damage to ornamental plants. The socialization and training involved ± 30 residents, where 100% of respondents expressed interest in trying to make their own biopesticides at home. Therefore, this program is planned to be further developed through regular mentoring and provision of practical guidelines in collaboration with the Karang Taruna of Desa Pulau Semambu so that the community can make biopesticides independently. This is in accordance with 97% of the community expressing openness to further similar community service activities.

Abstract

Acid Mine Drainage (AMD) generated by coal mining is commonly regarded as an environmental liability, yet it may also serve as a secondary source of Rare Earth Elements (REEs). This study evaluated the distribution, classification, and recovery potential of REEs in AMD water and sedimentation pond sludge from a coal mining area in South Sumatera, Indonesia. Four AMD water samples were collected from different mine pits, while two sludge samples were obtained from the inlet and outlet of a sedimentation pond. REEs concentrations were determined using Inductively Coupled Plasma–Mass Spectrometry, and recovery potential was assessed using the Outlook Coefficient and the relative proportion of critical REEs. The results showed that REEs concentrations in AMD water were low, ranging from 0.0005 to 0.449 ppm, with PIT 1 exhibiting the highest concentration under strongly acidic conditions. However, sludge samples exhibited considerable REEs enrichment with total concentrations of 178.13 ppm and 59.09 ppm at the inlet and outlet of the sedimentation pond, respectively. The preliminary outlook analysis showed low potential for direct recovery of REEs from AMD water, but sedimentation pond sludge, especially at the outlet, showed a promising outlook due to its combined high total REEs concentration and high critical content. This study showed that REEs can be recovered and concentrated in solid phases of AMD treatment systems. In addition, the sludge was a more viable and environmentally friendly secondary source.
