Analisis Ekologis Meiofauna Interstisial di Sekitar Pulau Pannikiang, Kabupaten Barru

Meiofauna were organisms that live in the interstitial. Synonyms were meiobentos. Meiofauna can also be interpreted as a small group of metazoans that sits between microfauna and macrofauna. This was caused by a very small body size and position was hidden in the sediments and did not provide direct benefits to humans (economic benefits). Meiofauna generally known only by scientists who pursue marine biology and ecology. This study aimed to determine the ecological water quality index based on the island of interstitial meiofauna Pannikiang, Barru district. The results showed that the class was the class that dominates the nematode composition and density of meiofauna in Pannikiang Island. Nematodes were very instrumental in the classroom enrich and enhance the productivity of aquatic ecosystems. Based on the ecological value of the index, the index of diversity (H'), Uniformity (E), and dominance (D) showed that P. Pannikiang have good water quality with the diversity of species and the spread of the number of individuals of each species were equal, a unified community and did not find any species that dominate the surrounding waters. Meiofauna ecology index indicates that the water condition in P. Pannikiang not currently experiencing a very severe ecological pressure, meaning that in a stable community structure, environmental conditions is excellent. Therefore, we need public participation and coordination among agencies in the District. Barru to maintain the condition of these waters

PEMANFAATAN TUMBUHAN SEKITAR SEBAGAI OBAT TRADISIONAL BAGI WARGA DESA PUUNDOHO KAB. KOLAKA UTARA

dipercaya mempunyai khasiat sebagai obat secara tradisional sehingga dapat digunakan sebagai upaya pengobatan mandiri. Desa Puundoho adalah salah satu desa yang terletak di Kab. Kolaka Utara, Sulawesi Tenggara. Mayoritas penduduk desa memiliki pekarangan dan kebun yang luas dikarenakan penduduk desa umumnya adalah petani. Pekarangan sebagai lingkungan hidup menyediakan berbagai sumber daya alam yang belum dimanfaatkan secara optimal, salah satunya adalah pemanfaatan tumbuhan sekitar. Banyak tumbuhan yang belum diketahui peranannya sebagai obat tradisional. Hal ini menyebabkan penduduk sangat tergantung pada obat-obatan kimia meskipun hanya untuk menangani penyakit ringan saja. Selain itu, tumbuhan tersebut dianggap gulma sehingga acapkali dimusnahkan, baik dengan penyemprotan herbisida ataupun dengan pembabatan. Hal ini tentu akan mengganggu ekosistem serta diversitas tumbuhan di lingkungan ini. Kondisi ketidaktahuan masyarakat Desa Puundoho, menjadi alasan dilakukannya pengabdian masyarakat ini. Tujuan kegiatan ini adalah untuk mengoptimalkan peranan tumbuhan yang ada disekitar sebagai upaya pengobatan mandiri serta untuk mendukung animo masyarakat “bact to nature”. Metode yang digunakan pada kegiatan ini adalah menggunakan ceramah yang sifatnya mengedukasi para peserta yang terdiri dari beberapa warga desa. Hasil pengabdian menunjukkan bahwa terjadi peningkatan pengetahuan masyarakat desa yang hadir pada saat kegiatan pengabdian tentang pemanfaatan tumbuhan sekitar sebagai obat tradisional. Hal ini terlihat dari kemampuan para peserta untuk menjawab pertanyaan dari tim pelaksana

Analisis Ekologis Meiofauna Sebagai Bioindikator Di Pesisir Pantai Losari, Makassar

Abstract.  The research aims to analyze ecological value of meiofauna as bioindicator in Losari Coast, Makassar. The total meiofauna abundance was 66791 indv/m2, consisted of 12 phylum and 91 species/genus. The stations located at the mouth of the Jeneberang River, Tanjung Merdeka, and the Tallo River  are research sites with high levels of abundance, due to the presence of organic contaminants produced by surrounding anthropogenic activity that trigger high growth of meiofauna.  ostracoda, oligochaeta, tunicata and ciliophora are the phylum with high levels of abundance compared to other meiofauna, as it that phylum has a high adaptability to the entry of pollutant material in the water. Diversity index and evenness indicates  the meioufauna in the Losari Coast categorized by a high level of diversity and evenly distributed. While  dominance index indicated that no dominant meifauna species, except at research stations located around the Losari Beach reclamation project.
