Abstract

Air merupakan sumber daya alam yang sangat penting bagi kelangsungan hidup manusia. Sumber daya air harus dilindungi agar manusia dan makhluk hidup lainnya dapat memanfaatkannya dengan baik. Air sungai yang keluar dari mata air biasanya mempunyai kualitas yang sangat baik. Namun dalam proses pengalirannya air tersebut akan menerima berbagai macam bahan pencemar. Terutama pada saluran drainase primer pengeringan IV Bukit Keminting Kelurahan Palangka, Kecamatan Jekan Raya, Kota Palangka Raya. Pencemar tersebut berupa limbah domestik yang berasal dari aktivitas penduduk dan perumahan penduduk yang membuang limbah ke sungai tanpa pengolahan terlebih dahulu, padahal mayoritas warga yang bermukim disekitar drainase masih memanfaatkan air tersebut. Oleh karena itu dilakukan pengujian kadar asiditas dan alkalinitas di sekitar saluran drainase. Pengambilan sampel dilakukan di sepanjang aliran drainase dan ditentukan kadarnya dengan menggunakan metode titrasi. Hasil penelitian menunjukkan rata-rata asiditas sebesar 35 mg/L. Berdasarkan PERMENKES No. 416/MEN.KES/PER/IX/1990, asiditas sampel masih memenuhi baku mutu air bersih. Sedangkan untuk kadar alkalinitas rata-rata sebesar 980 mg/L telah melebihi baku mutu air menurut Peraturan Pemerintah Nomor 82 Tahun 2001 Tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air. Kata kunci: asiditas, alkalinitas, baku mutu air.

Abstract

Habaring Hurung is one of the sub-districts in Bukit Batu District, Palangka Raya City, where most of the people work as farmers of vegetables and various types of flowering plants, such as Kenanga Flowers (Cananga odorata). However, the abundance of Kenanga flowers has not been utilized optimally by residents. Therefore, this service activity aims to improve entrepreneurial skills among people of productive age in Habaring Hurung Subdistrict by making reed diffuser aromatherapy products from Kenanga flowers. This service activity is carried out based on the ABCD method (asset-based community development) on September 4, 2023, at the Habaring Hurung Sub District Office Hall with 34 participants. The results showed that the activity participants stated the activity theme according to what was needed. Apart from that, the material presented is also easy to understand, so it can increase participants' knowledge and skills in processing Kenanga flower reed diffuser aromatherapy. This activity is expected to provide local residents with the knowledge and skills to utilize local materials in products of high economic and useful value.
