Abstract

Spons merupakan salah satu invertebrata filum Porifera yang menghasilkan senyawa aktif dengan berbagai variasi struktur dan salah satu aktivitas biologinya adalah sebagai antimikroba. Penelitian ini bertujuan untuk mengetahui ekstrak spons yang dapat menghambat pertumbuhan mikroba dan potensi senyawa aktif antimikroba dari spons asal perairan Pulau Barrang Lompo. Mikroba uji yang digunakan adalah Escherichia coli, Salmonella typhii, Staphylococcus aureus, dan Candida albicans. Bahan uji diperoleh dengan maserasi 14 buah sampel spons dengan metanol yang dilanjutkan dengan partisi berturut-turut menggunakan kloroform dan metanol, selanjutnya dilakukan uji KLT-bioautografi terhadap ekstrak yang aktif. Hasil penelitian menunjukkan bahwa ekstrak metanol dari sampel spons dengan kode BRLP-009 dan BRLP-010 mempunyai aktivitas paling potensial sebagai antimikroba.

Abstract

This paper provides an explanation of the condition of phytoplankton in the estuary waters of the west coast of South Sulawesi. The study was carried out on four estuaries namely Tallo, Marusu, Polong and Battoe with spatial sampling from inside the estuary to the outside of the estuary. The results obtained were found in three classes, namely Bacillariophyceae class, Cyanophyceae class, and Dinophyceae class with 19 phytoplankton genera. With an abundance of phytoplankton ranging from 352 - 5304 cells / L, the highest abundance is in the Tallo estuary. Meanwhile, the highest diversity index (H ') was found in Tallo estuary and the highest dominance index (D) was in Tallo estuary. Parameters that characterize high abundance estuaries are nitrate and TSS.

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).

Abstract

Sponges is one of the invertebrate Porifera phyla that produce active compounds with various structures and one of the biological activity as antimicrobial. The purpose of this research was to find out the sponge extracts that can inhibit microbial growth and potential of antimicrobial active compounds from sponge at Barrang Lompo Island. The microbes used were Escherichia coli, Salmonella typhii, Staphylococcus aureus, and Candida albicans. The sponge extracts were obtained by maceration 14 sponge samples with methanol, followed by partition using chloroform and methanol, then TLC-bioautography toward the active extract. The results showed that methanol extracts of sponge with code BRLP-009 and 010 have the most potential effect as antimicrobial agent.
