Abstract

Perairan pantai Kota Makassar, termasuk dua muara sungai yang mengapit, yaitu Sungai Jeneberang dan Sungai Tallo banyak mendapat inputan logam dari badan sungai dan dari daratan utama, berupa limbah industri dan limbah perkotaan.  Penelitian ini bertujuan untuk menentukan distribusi spasial konsentrasi Pb, Cd, Cu, dan Zn serta fraksi bioavailable di sedimen perairan pantai Kota Makassar. Penelitian dilakukan di wilayah perairan pantai Kota Makassar, mulai dari muara Sungai Jeneberang hingga muara Sungai Tallo. Pengukuran logam dilakukan pada sedimen berukuran < 63 μm. Spesiasi logam pada fraksi sedimen ditentukan dengan metode Community Bureau of Reference (BCR) Three-steps Sequential method yang menghasilkan fraksi exchangeable dan acid soluble, reducible, serta oxidisable. Interpolasi sebaran spasial logam di sedimen dilakukan dengan menggunakan teknik Sistem Informasi Geografis (SIG) yaitu block kriging (BK) dengan  program Arc View.  Sebaran logam sangat ditentukan oleh input atau sumber dari daratan dimana sebaran spasial logam Pb, Cd, Cu, dan Zn di sedimen meningkat ke arah utara pantai Kota Makassar.  Sebaran spasial fraksi 1 (terlarut dalam asam, acid reducible) logam Pb dan Cu tidak berbanding lurus dengan sebaran konsentrasi totalnya  di sedimen. Sedangkan sebaran spasial fraksi 1 logam Cd dan Zn berbanding lurus dengan sebaran konsentrasi totalnya di sedimen.

Abstract

Marine debris is defined as material that is solid, persistent, manufactured or processed, and deliberately or not-deliberately left in the marine environment. Marine debris comes in many shapes and forms, ranging in size from microscopic microplastics to large vessels. Marine debris is a big and growing global problem, pose threats to marine life sustainability. Plastic is a major component of marine debris, and single-use packaging accounts for an increasing part of the global marine debris load. Research on marine debris was conducted on coastal areas and Small Island of South Sulawesi destined for local tourism, i.e., Karama beach, Bodia beach and Mandi beach (Galesong, Takalar District), Tanjung Bayang beach, Akkarena beach and Lae-lae island/also known as Bob beach (Makassar City). This research was aimed at identifying marine debris according to its types, size, and mass. Debris was collected in a 25 x 60 m transect with direction 30 m towards land and waters, respectively, with 3 replication transects at every location, whilst collections of debris were conducted during low and high tides. Current (direction and speed) and waves (incoming direction and height) were also measured as supporting parameters. Surrounding sampling location characteristics were also recorded. The result showed that Karama beach is found with highest total marine debris mass in Takalar (36.44 kg), whilst in Makassar, the Lae-lae island was found to be the highest with debris mass (43.22 kg). Plastic was predominant debris at all sampling locations with percentages of 62.7 – 86.6%. Lastly, the predominant size was macro-debris (25-100 cm).
