Abstract

Dugong is the only herbivory mammals in the sea and mainly feed on seagrasses. Population of dugong tends to decrease in all ofits range as an impact from hunting, fishing activities and habitat degradation. In South Sulawesi-Indonesia, recent informationabout dugong population is unknown due to limited observation. Last dugong existence reported from Barranglompo Island in1991. This research aim to reveal the existence of dugong in Spermonde Archipelago. Result of this study showed from 1992to 2017, only 6 individu of dugong were observed. In 2006, one live dugong accidentally found roaming near Samalona Island.This encounter was successfully recorded by video camera. Four years later, one dead dugong found trapped in fishing net nearLantangpeo village, Tanakeke Island and sold to local fishermen for consumed. In 2014, one dugong grazing track was alsofound in Tanakeke Island near Balandatu Village. Information from 2016, reported two dugongs in seagrass meadow aroundPuntondo and Laikang Bay. Last report on 31 January 2017, showedone decomposed body from young dugong stranded inBarranglompo Island. The death cause remaining unknown. From interview with some witnesses and local fishermen, dugongaccidentaly found trapped, drown and dead in fishing net that set up around seagrass meadow. Captured dugong will on sale andslaughtered for its meat.With only once encountered alive in 25 years (which recorded by video camera), it can be concludedthat dugong population in Spermonde archipelago were extremely rare, heavily threatened and facing extinction.Keywords: dugong, sighting, Spermonde Archipelago, South Sulawesi

Abstract

The Research on “Coral Coverage in Baranglompo Island and Bone Batang Island Based on Reef Check Method” was conductedin April 2016. The aims of this study was to determine and to compare the condition of reefs in Baranglompo and Bone BatangIslands based on the percentage of life coral cover by using Reef Check methods. This study also aims to determine whichfactors that most affect the percentage of coral cover on each island i.e: abiotic factors (temperature, salinity and substrate inthe form of rock, rubble, sand, silt/clay); biotic factors (soft coral, recent killed coral, algae, sponges, fish and invertebratesassociate) and anthropogenic factors (garbage, ilegal fishing/bombs, stun, anchors, nets) were also investigated. Percentage oflife coral cover obtained by Line Intercept Transect (LIT) along 100 meters at a depth of 3 meters and 10 meters. The resultsshowed that the condition of coral reefs in Baranglompo was classified as moderate with an average percentage coral coverageof 42% at a depth of 3 meters and 27% at a depth of 10 meters. While the condition of coral reefs in Pulau Bone Batang wasrelatively good with average coral cover of 51% at 3 meters depth and moderate with average coral cover of 39% at 10 metersdepth. Condition of coral reefs in Bone Batang is better than Baranglompo islands. Anthropogenic impacts in the form of wasteis the most influential factor on coral cover on the island Baranglompo. Whereas fishing activities by using dinamite are thefactors that most influence on coral cover on the island of Bone Batang.Keywords: Coral coverage, Baranglompo island, Bone Batang island, Reef Check

Abstract

Penelitian tentang inventarisasi spesies tumbuhan di pulau Barrangcaddi yang berpenduduk padat telah dilakukan. Tujuan penelitian ini adalah untuk mengetahui jenis-jenis tumbuhan asli, tumbuhan introduksi dan tumbuhan invasif di Pulau Barrangcaddi. Kegiatan sampling dilakukan dengan metode purposive sampling. Data diambil dengan mencatat semua spesies tumbuhan yang ditemukan selama penjelajahan di pulau Barrangcaddi. Seluruh sampel di foto. Sampel tumbuhan yang tidak diketahui namanya, di ambil bagian-bagiannya, kemudian dikoleksi dan diidentifikasi di laboratorium Ilmu Lingkungan dan Kelautan, Departemen Biologi, Fakultas MIPA, Universitas Hasanuddin. Identifikasi sampel menggunakan buku: An Annotated Check-List of The Vascular Plants of The South China Sea and Its Shores oleh Turner et al. (2000) dan Mangrove Guidebook for Southeast Asia oleh Wim Giesen et al. (2007) untuk spesies hutan pantai; Tropical flowering plants: a guide to identification and cultivation oleh Kirsten Albrecht Llamas (2003) untuk spesies tanaman hias dan tanaman budidaya/introduksi serta Nonnative Invasive Plants of Pacific Coast Forest. A Field Guide for Identification oleh Gray et al. (2011) dan Guide to The Naturalized and Invasive Plants of Southeast Asia oleh Arne Witt (2017) untuk spesies tumbuhan invasif. Dari hasil penelitian di pulau Barrangcaddi tercatat sebanyak 142 spesies tumbuhan dari 51 suku. Sebagian besar didominasi oleh tanaman hias dan budidaya (introduksi) dengan 103 spesies dari 42 suku diikuti spesies asli (native species) dengan jumlah 29 spesies dari 19 suku. Spesies invasif tercatat paling sedikit dengan jumlah 10 spesies dari 5 suku. Sebagian besar tutupan vegetasi dari spesies asli telah hilang akibat alih fungsi lahan menjadi permukiman.
