ABSTRAKKata kunci: dampak, manajemen, Pulau Selayar, sampah plastik, sosial-ekonomi ABSTRACT Enormous plastic debris has been stranded on Selayar island shore during the west monsoon due to its position which is directly faced Java sea. Plastic debris had impacted social and economy of Selayar fishermen. The research was aimed to determine the composition, density, and distribution of the plastic debris; it impacts to social and economy. Line transect was used as the research method to quantify the numbers and width of the plastic debris spread. The size of plastic debris that was researched about >2,5 cm which categorized as macro litters. The research was conducted in February to March 2016. The impacts of plastic debris were reduce income from tourism, fishing industry, disrupting fishing operations, requiring clean-up, and repairing vessel. Direct costs for repair and clean-up fishing vessels was about 192.9 million rupiahs per year and repair fishing gears was about 156.2 million rupiahs per year. The plastic debris consists of plastic bottle, plastic cup, rope and fish net, gas matches, plastic box, buoy, food packaging, toothbrush and syringe. The average of plastic debris about 9.5 ± 2.7 item/m 2 and weight about 229.2 ± 109.9 g/m 2 .

ABSTRAKBioaktif antioksidan merupakan substansi yang penting bagi kesehatan manusia. Karang lunak telah diketahui memproduksi bioaktif dengan keragaman struktur dan aktivitas biologi, termasuk memproduksi bioaktif antioksidan. Tujuan penelitian ini adalah untuk mendapatkan bioprospeksi karang lunak dari perairan Teluk Palu sebagai penghasil antioksidan. Penelitian meliputi pengambilan sampel, identifikasi, ekstraksi (maserasi) karang lunak, skrining konstituen kimia, pengujian aktivitas antioksidan (penangkapan radikal DPPH), dan penentuan IC 50 . Pengambilan sampel dilakukan di Teluk Palu, pesisir desa Kabonga Besar, Kabupaten Donggala, Sulawesi Tengah. Berdasarkan bentuk koloni monomorfik, tujuh sampel karang lunak yang digunakan pada penelitian ini termasuk dalam genus Sinularia, Dampia dan Sarcophyton. Analisis konstituen kimia mengindikasikan adanya senyawa saponin, fenolik, triterpenoid, dan alkaloid. Hasil pengujian aktivitas antioksidan dengan metode DPPH, menunjukkan ekstrak kasar karang lunak menunjukkan persentase inhibisi radikal DPPH yang lemah. Hasil pengujian aktivitas antioksidan (metode DPPH) dari fraksi hasil partisi tujuh ekstrak kasar karang lunak berpotensi sebagai antioksidan dengan kategori kuat sampai lemah. Dari hasil penelitian dapat disimpulkan bahwa ekstrak karang lunak asal Teluk Palu berpotensi sebagai sumber antioksidan. Karang lunak di pesisir Desa Kabonga Besar didominasi oleh genus Sinularia. ABSTRACTThe antioxidants substances are important for human health. Soft corals have been known to produce compounds with a variety of structural and biological activities, including bioactive antioxidants. The aim of this research was to obtain information of soft coral bioprospection from Palu Bay as an antioxidant. The research included sampling, identification, extraction (maceration) of soft corals, screening of chemical constituents, antioxidant activity assay (DPPH's radical scavenger), and determination of IC 50 . Soft coral samples were collected from Palu Bay, coastal village of Kabonga Besar, Donggala District, Central Sulawesi. Based on the shape of the monomorphic colony, seven soft coral samples that were used in this study belong to the genus Sinularia, Dampia and Sarcophyton. Analysis of chemical constituents indicated the presence of saponin compounds, phenolics, triterpenoids, and alkaloids. The results of the antioxidant activity by DPPH method showed that soft coral crude extracts have a weak percentage of DPPH's radical inhibition, while the results of the fraction had potential to be antioxidants with strong to weak categories. From the results of this study, it concluded that the soft coral extracts from Palu Bay have the potential as a source of antioxidants. The genus Sinularia dominates soft coral on the coast of Kabonga Besar Village.

Program Kemitraan Masyarakat Stimulus (PKMS) Pemantauan Ikan Endemik Banggai Cardinalfish (BCF) Pasca Tsunami di Teluk Palu bertujuan untuk meningkatkan pengetahuan dan ketrampilan siswa/siswi SMKN 6 Palu terhadap ikan endemik BCF dan habitatnya. Kemampuan tersebut semakin penting dalam konteks pembangunan berkelanjutan dan perubahan iklim. Dengan demikian, pengetahuan mengenai ikan endemik BCF serta keterampilan memantau ikan tersebut merupakan life skills yang sangat berguna bukan hanya bagi mereka tetapi bagi komunitas dimana mereka berada, baik selama duduk di bangku sekolah maupun nantinya di tengah masyarakat. Tahap Pelaksanaan PKMS ini melalui penyuluhan pelatihan teknis bioekologi dan cara pemantauan ikan endemik BCF secara daring yang di sampaikan oleh narasumber teknis, kemudian dilanjutkan dengan penerapan skala kecil dilapangan oleh tim pelaksana. Hasil Survei menunjukkan bahwa adanya perubahan yang sangat signifikan baik itu menyangkut jumlah populasi maupun mikrohabitat ikan endemik BCF

Mangroves are plants with good tolerance to salinity changes, developing a chemical defense system with pharmacological value. This study aimed to obtain a GC-MS profiles of Rhizophora apiculata mangrove leaves extract, which could scavenge DPPH radicals and inhibit the growth of Listeria monocytogenes, Salmonella typhimurium, and Pseudomonas aeruginosa. The research included sampling, extraction (maceration with MeOH:DCM), identification of chemical profiles using GC-MS spectra analysis, assaying for antibacterial activity (well diffusion method), and antioxidants (DPPH radical scavenging). Mangrove leaves sampling was carried out on Laemanta, Parigi Moutong, Central Sulawesi. Based on the leaves' characteristics and tips, the types of roots, fruits, and flowers, the mangrove leave samples were identified as R. apiculata. The GC-MS profiles of R. apiculata leaves extract was dominated by mome inositol (75.6%). The antibacterial assay showed at a concentration of 100 mg/mL of R. apiculata leaves extract showed weak to strong antibacterial activity, with the inhibition zone diameter of P.

Catfish is one of potential fisheries products in Central Sulawesi, but this fact is not in line with community consumption level. Catfishes contain protein and fatty acid which are good for health. The use of catfishes as fish chips become one of the way out to increase the community consumption level. This research aims at knowing the effect of catfishes protein concentration toward chemical content (water content, ash content) and organoleptics. The research result shows that the treatment of catfishes protein concentration is unsignifficantly effect the water and ash content, besides the result of hedonic test shows that the concentration signifficantly effect the taste, the smell and the texture of catfish chips but unsignifficanly effect the colour of it. The treatment by adding 200 g of catfish was being the panels’ most favorite treatment with a score of 4.5 or with the rounding 5 indicated as favored.
