Taman Nasional Sembilang merupakan salah satu taman nasional yang terletak di Sumatera Selatan dan menjadi kawasan mangrove terbesar di barat Indonesia. Sebagian besar wilayah mangrovenya telah mengalami alih fungsi menjadi tambak pasang surut. Hal ini menyebabkan timbulnya kekhawatiran kerusakan mangrove di taman nasional. Salah satu upaya untuk mempertahankan wilayah mangrove adalah dengan melakukan sistem silvofishery, yaitu penanaman mangrove dan budidaya bandeng dilakukan secara bersamaan di tambak. Penelitian ini bertujuan untuk menganalisis kualitas air dan kondisi nutrien di tambak di daerah restorasi silvofishery di Taman Nasional Sembilang. Penelitian dilakukan dengan metode purposive sampling di tambak silvofishery, tambak non-silvofishery, dan badan air sungai di seluruh wilayah taman nasional. Pengukuran dilakukan terhadap parameter kualitas air dan kandungan nutrien khususnya nitrat dan fosfat. Hasil penelitian menunjukkan bahwa kehadiran tanaman mangrove di daerah tambak mampu memperbaiki kandungan oksigen dan pH air tambak. Mangrove juga menunjukkan kemampuan dalam mengikat nitrat yang secara tidak langsung akan mencegah air tambak dari polusi. Namun, kandungan fosfat tinggi menunjukkan bahwa tanaman mangrove muda di wilayah restorasi belum mampu mengikat nutrien ini secara signifikan. Hasil penelitian ini menunjukkan bahwa hutan mangrove sangat bermanfaat bagi kegiatan budidaya tambak karena kemampuannya dalam menyerap polutan nutrient. Kata kunci: silvofishery; kolam; nitrat; fosfat; Taman Nasional Sembilang Sembilang National Park is one of the national parks which is located in South Sumatera and became the largest mangrove area in western Indonesia. Most of the mangroves area in this national park has been experiencing conversion to be tidal ponds. This has resulted in concerns on mangrove forest destruction in the park. One of the efforts to maintain mangroves area is by applying silvofishery system, which is mangrove planting and cultivation of milkfish in ponds performed simultaneously. This study aims to investigate the water quality and nutrient condition in the ponds in the area of silvofishery restoration at Sembilang National Park. The study was conducted by purposive sampling method in the silvofishery ponds, non-silvofishery ponds, and river water bodies throughout the park. Measurements conducted on water quality parameters and nutrient content, especially nitrate and phosphate. The results showed that the presence of mangrove in the ponds area is able to improve the oxygen content and pH of pond water. Mangroves also demonstrated the ability to bind nitrates which indirectly will prevent the pond water from pollution. However, the high phosphorus content showed that young mangrove plants in the restoration area have not been able to significantly bind the of this nutrient. The results of this study showed that mangrove forests are very beneficial for aquaculture activities because of its ability to absorb nutrient pollutants.

The Impact

Eleven billion microplastic particles are entangled in coral reef ecosystems in the Asia - Pacific Region. The presence of microplastics in coral reef ecosystems in Indonesia, especially in the Karimunjawa Marine National Park, was found as many as 22.7 and 12.8 particles / kilogram samples in two locations. The presence of microplastics in coral reef ecosystems allows threats to the health of coral reefs. Therefore, the importance of this study is to complement the data on the distribution of microplastics in the Karimunjawa Marine National Park as an initial step for conservation and mitigation of the impact of plastic/ microplastic pollution. Sampling using purposive sampling method. Sediment collection using SCUBA set and sediment grab at a depth of 3 - 5 meters. ± 1000 g of sediment was taken and stored in double zip lock plastic. The samples were then analyzed by microplastics in the Tropical Marine Biotechnology Laboratory, FPIK UNDIP. The results showed that the greatest abundance of microplastics was in the Karang Tengah area with the number of microplastics 96 particles / kilogram, and the farthest in the Ujung Gelam and Lego was 11 particles / kilogram. Research shows that the abundance of microplastics in areas with human activities such as tourism, ports, and boat routes has a high abundance compared to conservation areas or areas with little human activity. It is hoped that the available data from this type of research will be able to produce decisions on conservation measures in Karimunjawa Marine National Park.  Sebelas miliar partikel mikroplastik terjerat pada ekosistem terumbu karang di Kawasan Asia – Pasifik. Keberadaan mikroplastik pada ekosistem terumbu karang di Indonesia, khususnya di Taman Nasional Laut Karimunjawa, ditemukan sebanyak 22,7 dan 12,8  partikel/kilogram sampel di dua lokasi. Keberadaan mikroplastik di ekosistem terumbu karang memungkinkan adanya ancaman terhadap kesehatan terumbu karang. Oleh karena itu pentingnya penelitian ini untuk melengkapi data sebaran mikroplastik di Kawasan Taman Nasional Laut Karimunjawa sebagai langkah awal konservasi dan mitigasi dari dampak polusi plastik/mikroplastik. Pengambilan sampel menggunakan metode purposive sampling. Pengambilan sedimen menggunakan SCUBA set dan sediment grab pada kedalaman 3 – 5 meter. Sedimen diambil ± 1000 gr dan disimpan dalam plastik double zip lock. Sampel kemudian dianalisis mikroplastik di laboratorium Tropical Marine Biotechnology, FPIK UNDIP. Hasil menunjukkan bahwa kelimpahan mikroplastik terbesar pada daerah karang tengah dengan jumlah mikroplastik 96 partikel/kilogram, dan terkecil pada perairan ujung gelam dan lego yaitu sebanyak 11 partikel/kilogram. Penelitian menunjukkan bahwa kelimpahan mikroplastik didaerah dengan aktivitas manusia seperti pariwisata, pelabuhan, dan jalur kapal memiliki kelimpahan tinggi dibanding dengan daerah konservasi atau daerah dengan aktivitas manusia yang kecil. diharapkan dengan data yang tersedia dari penelitian sejenis ini, mampu menghasilkan keputusan terhadap langkah konservasi di Taman Nasional Laut Karimunjawa.

Ekosistem mangrove memiliki fungsi ekologis sebagai penyerap dan penyimpan karbon. Mangrove menyerap CO2 pada saat proses fotosintesis, kemudian mengubahnya menjadi karbohidrat dengan menyimpannya dalam bentuk biomasa. Tujuan penelitian untuk mengestimasi simpanan karbon pada tegakan dan substrat mangrove yang berada di Desa Pasar Banggi dan Desa Tireman, Kabupaten Rembang. Pengambilan sampel dilakukan pada bulan Juni - Juli 2018. Metode yang digunakan yaitu purposive sampling method dan eksploratif, dengan dasar pertimbangan berupa jenis, kerapatan serta diameter pohon mangrove. Pengambilan sampel dilakukan di tiga stasiun dengan kondisi rapat, sedang dan jarang. Setiap stasiun penelitian dibagi menjadi tiga plot penelitian, pengukuran diameter pohon dilakukan pada transek ukuran 10 x 10 m, diameter yang di ukur pada setiap plot yaitu hanya kategori pohon (diameter ≥ 5 cm). Berdasarkan hasil penelitian, didapat bahwa simpanan karbon pada tegakan mangrove di Desa Pasar Banggi sebesar 9.620,451 ton/ha, dan Desa Tireman sebesar 4.633,618 ton/ha, sedangkan estimasi simpanan karbon pada substrat mangrove di Desa Pasar Banggi sebesar 920,982 ton/ha dan Desa Tireman sebesar 471,929 ton/ha. Mangrove ecosystems have ecological functions as carbon sinks and stores. Mangroves absorb CO2 during photosynthesis, then convert it to carbohydrates by storing it in the form of biomass in the body parts of mangrove plants. Research on the estimation of carbon stocks is very necessary to support the improvement of world climate. The sampling was conducted on June 2018 until July 2018. This research used  purposive sampling and explorative method, with the consideration of the type, density and diameter of mangrove trees. Conducted in three stations with varying in the mangrove ecosystem conditions. Each research station was divided into three research plots, tree diameter measurements were carried out on 10 x 10 m transects, the diameter measured in each plot was only trees (≥ 5 cm diameter). The result of this research, it is found that carbon storage in mangrove stands Pasar Banggi Village is 9,620,451 ton/ha, and Tireman Village is 4,633,618 ton/ha. While  estimated carbon storage the mangrove substrate in Pasar Banggi Village is 920,982 ton/ha and Tireman Village is 471,929 ton/ha. These result that estimates carbon storages in mangrove stands are greater than estimates of carbon storage on mangrove substrate. The estimation of carbon storage in the mangrove stands increases with increasing of plant biomass and mangrove density, while estimates of carbon storage on the substrate are tsuspected to be more influenced by organic matterial and the location reseach.
