Sagu (Metroxylon spp) merupakan tumbuhan palem tropika basah, memiliki adaptasi kuat untuk tumbuh pada lahan marjinal seperti lahan tergenang air tawar, lahan gambut, dan air payau. Penelitian bertujuan :(1) melakukan analisis untuk menjelaskan sifat pertumbuhan sagu dalam komunitas alami, (2) mengungkapkan preferensi habitat tumbuhan sagu, (3) melakukan analisis interaksi tumbuhan sagu dengan faktor lingkungan, dan (4) mengungkapkan potensi tegakan dan produksi pati sagu. Penelitian berlangsung di tiga wilayah di pulau Seram, Maluku secara keseluruhan, tentu dengan menggunakan sampling, bukan menggunakan metode sensus pada bulan Maret-Nopember 2009. Hasil penelitian menunjukkan bahwa struktur populasi sagu dalam komunitas alami mengikuti pola pertumbuhan muda dengan tingkat kematian pada fase semai sekitar 85. Di Pulau Seram terdapat lima jenis sagu yaitu tuni, makanaro, sylvestre, rotang, dan molat. Sagu tuni merupakan spesies dominan dengan penguasaan habitat mencapai 43,3%. Serta memiliki daya adaptasi yang tinggi pada berbagai tipe habitat. Dalam beradaptasi dengan kondisi habitat tergenang, perakaran sagu mengalami modifikasi arah pertumbuhan menuju permukaan air dengan jumlah yang lebih banyak. Dalam komunitas sagu terjadi asosiasi antarspesifik secara negatif dengan Jaccard indeks < 0,2. Variabel iklim, tanah, dan kualitas air rawa yang memiliki peran kuat dalam pertumbuhan sagu masing-masing adalah intensitas cahaya surya mikro, kapasistas tukar kation (KTK), dan kandungan kalsium air. Di Pulau Seram terdapat potensi populasi rumpun sagu sekitar 3,2 juta rumpun dengan jumlah tegakan fase pohon mencapai 1,5 juta batang. Jenis sagu tuni dan sylvestre merupakan jenis sagu potensial dengan kapasitas produksi masing-masing 566,04 kg dan 560,68 kg/batang.

Seiring dengan peningkatan jumlah penduduk di daerah pesisir, tekanan terhadap ekosistem pantai semakin meningkat pula. Untuk mengetahui dampak dari aktifitas anthropogenik terhadap status hara (karbon, nitrogen dan fosfor) pada lamun telah dilaksanakan penelitian pada dua pulau di Kepulauan Spermonde yakni Pulau Barranglompo dan Bonebatang. Kedua pulau ini mendapat tekanan anthropogenik berbeda. Sampel diambil dari daun lamun Enhalus acoroides pada tiga stasiun dengan jarak berbeda dari garis pantai pada masing-masing pulau. Hasil pengukuran hara menunjukkan bahwa konsentrasi nitrogen di Pulau Barranglompo jauh lebih tinggi dibandingkan Pulau Bonebatang. Nilai rasio C:N yang lebih rendah dan nilai rasio N:P yang lebih tinggi di Pulau Barranglompo memperkuat hal ini. Perbedaan ini mengindikasikan pengaruh dari pengayaan hara akibat aktifitas anthropogenik yang semakin meningkat. Hal ini didukung oleh nilai Total Padatan tersuspensi yang jauh lebih tinggi di Pulau Barranglompo dibandingkan Pulau Bonebatang. Aktifitas anthropogenik yang paling potensial mempengaruhi komposisi hara di Pulau Barranglompo adalah pembuangan sampah rumah tangga dan aliran limbah cair dari rumah penduduk di sekitar pantai. Kata kunci: lamun, hara, rasio C:N:P, aktifitas anthropogenik, Barranglompo, Bonebatang As human population increase in coastal areas, significant pressure to the coastal ecosystem increase as well. In order to reveal possible impacts of anthropogenic activities to the nutrient status of seagrasses, a study has been done in two small islands within Spermonde Archipelago i.e. Barranglompo and Bonebatang Islands. Currently, these two islands are facing different anthropogenic pressure. Samples of seagrass Enhalus acoroides were collected from three stations based on their different distances from the shoreline. Results of the nutrient measurements showed that nitrogen concentrations in Barranglompo Island were significantly higher than those in Bonebatang Island. This was supported by lower C:N ratios and higher N:P ratios in Barranglompo Island. This difference indicated influence of nutrient enrichment due to increased anthropogenic activities. Significantly higher Total Suspended Solid (TSS) values were also a strong evidence of this process. Potential anthropogenic activities affecting nutrient composition in Barranglompo Island are domestic sewage disposal and drainage of liquid household sewage. Key words: seagrass, nutrient, C:N:P ratio, anthropogenic activities, Barranglompo, Bonebatang

Penelitian ini bertujuan untuk menganalisis, menguraikan struktur, dominasi vegetasi mangrove, zonasi, dan permudaan alami di Pulau Kaledupa Taman Nasional Wakatobi. Sampling vegetasi menggunakan metode transek garis dan metode plot. Data vegetasi mangrove diperoleh melalui pengamatan dari setiap plot. Untuk strata pohon, tiang dan sapihan, parameter yang diamati meliputi nama spesies, jumlah individu masing-masing spesies, dan ukuran diameter batang setinggi dada. Sedangkan untuk strata semai dihitung jumlah cacah individu masingmasing spesies. Data periode dan tinggi penggenangan pada saat air pasang, diukur pada plot pengamatan setiap hari selama 30 hari. Dominasi vegetasi mangrove ditentukan dengan parameter nilai penting, zonasi dengan parameter kerapatan relatif, dan permudaan alami vegetasi mangrove dianalisis dengan menggunakan nilai kerapatan total semai setiap plot pengamatan. Hasil penelitian menemukan bahwa komunitas mangrove di Pulau Kaledupa pada strata pohon didominasi oleh spesies Bruguiera gymnorrhiza, strata tiang didominasi oleh spesies Rhizophora mucronata, dan pada strata sapihan dan semai didominasi oleh spesies Ceriops tagal. Zonasi mangrove di Pulau Kaledupa terdiri atas empat zona, yaitu Zona R. mucronata, R. apiculata, Ceriops tagal, dan C.decandra. Tinggi penggenangan air laut merupakan faktor pengendali terjadinya zonasi mangrove di Pulau Kaledupa. Spesies C.tagal dan C.decandra memiliki tingkat permudaan alami baik, sedangkan spesies R. mucronata, R.apiculata, B.gymnorrhiza, Xylocarpus granatum, Sonneratia alba, dan Avicennia marina memiliki permudaan secara alami rendah. Kata kunci: Vegetasi mangrove, zonasi, struktur, komposisi This research was aimed to describe the structure, dominance of mangrove vegetation, zonation, and natural regeneration at Kaledupa Island of Wakatobi National Park. Sampling of vegetation used line transect and plot methods. Data of mangrove vegetation was obtained through observation of each plot at all growth phases (trees, poles, sapling and seedling) covering species name, number of individual of each species, and size of the breast height diameter of stem. Data of water inundation at high tide was measured at each observation plot. Observation was conducted for 30 days. Dominance of mangrove vegetation was determined by importance value parameter, zonation by relative density parameter and natural regeneration by seedling density. Results of this research found that mangrove community at Kaledupa Island at trees stratum were dominated by species Bruguiera gymnorrhiza, poles stratum was dominated by species Rhizophora mucronata, and at sapling and seedling stratum were dominated by species Ceriops tagal. Mangrove zonation at Kaledupa Island consisted of four zones, that are R. mucronata, R. apiculata, C. taga, and C. decandra zone. Height of seawater inundation is controlling factor of formation of mangrove zonation at Kaledupa Island. Species C. tagal and C. decandra had high level of natural regeneration, while species R.mucronata, R. apiculata, B. gymnorrhiza, Xylocarpus granatum, Sonneratia alba, and Avicennia marina had low natural regeneration. Key words : mangrove, zonation, structure, composition

The invasion of the planter's rhododendron (Melastoma malabatrichum) in Way Kambas National Park caused the loss of the sumatran tiger preys feeding ground, therefore efforts were made to eradicate the plant. This study aimed to compare the presence of sumatran tiger preys between M. malabatrichum-invaded location and eradicated location. Eradication was carried out by removing M. malabatrichum on a plot measuring 80 x 60 m2. To record the animal visit, the camera traps were placed at the eradicated and invaded location of M. malabatrichum for comparison. The results showed that the M. malabatrichum eradicated location was more frequently visited by sumatran tiger preys. At the M. malabatrichum eradicated location, camera traps recorded 19 species of wild boar having the highest encounter rate (55.23) followed by sambar deer (33.24), and long-tailed macaque (17.43). Meanwhile, at the M. malabatrichum invaded location, camera traps recorded 13 species with wild boar having the highest encounter rate (30.56), followed by sambar deer (14.75), and long-tailed macaque (14.48). Thus, the eradication of M. malabatrichum had a good impact on increasing the number of sumatran tiger preys due to the availability of feed after being free from M. malabatrichum invasion.
