The study evaluated the possibility of using mangrove plantation to treat municipal wastewater. Two types of pilot scale (100 × 150 m2) free water surface constructed wetland were set up. One system was a natural Avicennia marina dominated forest system. The other system was a newly planted system in which seedlings of Rhizophora spp., A. marina, Bruguiera cylindrica and Ceriops tagal were planted in 4 strips. Municipal wastewater was retained within the systems for 7 and 3 days, respectively. The results indicated that the average removal percentage of TSS, BOD, NO3-N, NH4-N, TN, PO4-P and TP in the newly planted system were 27.6-77.1, 43.9-53.9, 37.6-47.5, 81.1-85.9, 44.8-54.4, 24.7-76.8 and 22.6-65.3, respectively. Whereas the removal percentage of those parameters in the natural forest system were 17.1-65.9, 49.5-51.1, 44.0-60.9, 51.1-83.5, 43.4-50.4, 28.7-58.9 and 28.3-48.0, respectively. Generally, the removal percentages within the newly planted system and the natural forest system were not significantly different. However, when the removal percentages were compared with detention time, TSS, PO4-P and TP percentages removed were significantly higher in the 7-day detention time treatment. Even though the removal percentages were highly varied and temporally dependent, the overall results showed that mangrove plantation could be used as constructed wetland for municipal wastewater treatment in a similar way to the natural mangrove system.

Mangrove forests are unique ecosystems that have ecological, biological and socio-economic functions. The function of mangrove forests on the environment is very important especially in the coastal and oceanic regions. Mangrove forests providers of wood, leaves as raw material for medicines, and natural dye. This study aims to inventory the diversity of species of mangrove vegetation in Mendalok Village, Sungai Kunyit Subdistrict, Mempawah Regency. The benefits of this study are to provide the data on mangrove forest vegetation as basic data for local government and related agencies in efforts to protect and preserve mangrove forests in Mendalok Village, Sungai Kunyit Subdistrict, Mempawah Regency. Inventory the tree in mangrove forest used a line with measured 200 meters. There are 6 lines and the distance between the lines as far as 100 meters. The lines of observation are placed by purposive sampling. The results of research found 11 types of species and consisted of 6 genera. The genera are Avicennia, Bruguiera, Ceriops, Rhizophora, Soneratia and Xylocarpus. The species found were Avicennia alba, Avicennia marina, Bruguiera cylindrica, Bruguiera gymnorrhiza, Bruguiera parviflora, Ceriops decandra, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, Sonneratia caseolaris, Xylocarpus mollucensis. Diversity of mangrove species in Mendalok Village, Sungai Kunyit Subdistrict, Mempawah Regency was high and should be maintained for conservation and ecotourism area.

Daerah penelitian terletak di Kabupaten Nabire, Papua yang sebagian besar wilayahnya ditutupi endapan Kuarter. Penelitian bertujuan untuk mengungkap dinamika Kuarter serta interval proses pengendapan berdasarkan aspek sedimentologi dan stratigrafi. Metode yang dilakukan adalah pemboran dangkal menggunakan hand auger sebanyak 48 titik. Hasil pengeboran menunjukkan  7 (tujuh) fasies pengendapan, yaitu: endapan limpah banjir, endapan cekungan banjir, endapan sungai, endapan rawa bakau, endapan pantai, endapan laut dekat pantai, dan batuan pra-Holosen. Berdasarkan rekonstruksi penampang stratigrafi, kelompok fasies pengendapan tersebut terbagi menjadi dua interval periode pengendapan. Interval periode pengendapan pertama merupakan fasies muka airlaut tinggi (transgresi) dan tersusun atas sistem laut dan sistem rawa. Interval periode pengendapan kedua merupakan fasies muka airlaut rendah (regresi) dan tersusun atas sistem laut, sistem rawa dan sistem sungai. Hasil pentarikhan umur menggunakan metode pentarikhan radiokarbon menunjukkan bahwa batas antara periode pertama dan periode kedua terjadi pada kisaran umur 9.200-10.700 tahun yang lalu. Kemunculan sistem sungai pada periode kedua diakibatkan oleh turunnya muka air laut. Kondisi ini menunjukkan kecenderungan tingkat energi semakin mengecil, berkaitan dengan jumlah volume air ketika itu. Jumlah volume air tersebut berhubungan dengan tingkat kelembapan yang bergantung pada siklus perubahan iklim. Fasies endapan rawa bakau dicirikan dengan keterdapatan Rhizophora sp., Sonneratia alba, dan Bruguiera cylindrica, terjadi penipisan endapan gambut pada fasies tersebut. Peristiwa tersebut menunjukkan bahwa iklim menuju ke kering. Munculnya fasies pantai di bagian tengah fasies endapan rawa bakau membuktikan bahwa ketika muka airlaut turun secara global, secara lokal muka airlaut tinggi pada periode tertentu. Gejala ini cenderung berkaitan dengan turunnya dasar cekungan (base level) akibat tektonik.Katakunci : Muka air laut, tektonik, iklim, Holosen, Nabire

Mangrove litter production is important in the displacement of organic matter from mangrove vegetation to water such as in the coast of West Muna Regency. However, one factor influencing it is the frequency of rainfall. This research, therefore, aims to determine the influence of the frequency of rainfall in mangrove ecosystem by obtaining data through the fractional wet weight. The results showed that the biomass fraction with the largest amount were Rhizophora mucronata, Rhizophora apiculata, and Sonneratia alba with of 31.59; 31.07; and 30.96%, respectively, while the lowest was Rhizophora stylosa, Bruguiera cylindrica, and Bruguiera gymnorrhiza with of 30.07; 30.10; and 31.95%, respectively. The species with the largest leaf litter production was Bruguiera cylindrica, with of 1.72 g.m-2.day-1 which occurred in April and the lowest was Rhizophora apiculata, 0.24 g.m-2.day-1 in August. The species with the largest leaf litter production was Bruguiera cylindrica, 1.96 g.m-2.day-1 which occurred in May and the lowest was Sonneratia alba, 0.29 g.m-2.day-1 in August. In addition, the species with the largest fruit litter production was Rhizophora apiculata, 1.76 g.m-2.day-1 in April and the lowest was Sonneratia alba, 0.32 g.m-2.day-1 in September. The total litter production was 18,75 g.m-2.day-1 consisted of 6,69 g.m2.day-1 leaf litter, 6,54 g.m-2.day-1 branch litter, and 5,52 g.m-2.day-1 fruit litter. The higher the frequency of the rain, the greater the litter production.   Keywords: biomass fraction, seasonal litter production, West Muna Regency

Penelitian dilakukan pada bulan Mei sampai bulan September 2017 bertujuan untuk memperoleh informasi tentang keragaman, potensi jenis dan kandungan karbon pada hutan mangrove, di Kepulauan Lepar Pongok, Bangka Selatan. Metode yang digunakan yaitu pusposive sampling, setiap lokasi dibuat sepuluh plot contoh ukuran 10m x 10 m jarak antar plot 50 m, dalam plot tersebut dibuat sub plot ukuran 5 m x 5 m untuk tingkat belta dan 2 m x 2 m untuk tingkat semai. Hasil penelitian di lokasi tersebut didominasi oleh <em>Rhizophora mucronata</em> Blume, <em>Rhizophora apiculata </em>Blume,<em> Bruguiera cylindrica</em> W.et.A., dan<em> </em><em>Sonneratia caseolaris </em>(L) Engl. dengan kerapatan masing-masing 886 pohon/ha, 626 pohon/ha, 495 pohon/ha dan 263 pohon/ha. Regenerasi hutan mangrove di lokasi penelitian cukup baik, untuk jenis <em>Sonneratia caseolaris </em>(L) Engl. regenerasinya tidak sempurna yaitu tidak terdapat di tingkat belta. <em>Rhizophora mucronata</em> Blume mempunyai biomassa sebesar 146,75 ton/ha diikuti oleh jenis <em>Rhizophora apiculata </em>Blume sebesar 102,25 ton/ha dan <em>Bruguiera cylindrica</em> W.et.A. sebesar 98,42 ton/ha. Total biomassa di lokasi penelitian sebesar 387,51 ton/ha.<strong> </strong>Biomassa hutan mangrove berdasarkan jenis di Kepulauan Lepar Pongok didominir jenis <em>Rhizophora mucronata</em> Blume sebesar 358,62 ton/ha (setara 179,31 ton C/ha atau 658,07 ton CO<sub>2</sub>/ha).
