Abstract

Abstrak. Ikan gelodok atau Mudskipper merupakan ikan yang hidup di daerah pasang-surut. Ikan ini mampu berjalan di atas lumpur, bahkan mampu memanjat akar-akar mangrove. Informasi tentang kajian mengenai ikan gelodok di Indonesia masih sedikit. Untuk itu diperlukan informasi lebih lanjut tentang jenis-jenis ikan dan tipe habitat yang paling sering ditemukan ikan gelodok. Penelitian dilaksanakan pada bulan Maret 2014 sampai dengan April 2014. Pengambilan contoh ikan gelodok pada 3 daerah yaitu, pantai, mangrove dan sungai/saluran. Identifikasi jenis ikan gelodok mengacu pada Kottelat et al., (1993). Selanjutnya dihitung kepadatan ikan sesuai titik pengamatan. Hasil penelitian ditemukan 4 jenis ikan gelodok yaitu: Boleophthalmus boddarti, Periophthalmus chrysospilos, Periophthalmus gracilis dan Periophthalmonodon schlosseri. Rata-rata kepadatan ikan gelodok selama masa penelitian adalah 9 ind/m2 untuk di wilayah pantai, 1 ind/m2 di wilayah mangrove dan 6 ind/m2 pada saat kondisi air laut pasang. Pada saat kondisi air laut surut, kepadatan ikan gelodok adalah 4 ind/m2 untuk daerah pantai, 2 ind/m2 untuk daerah mangrove dan 7 ind/m2 untuk daerah sungai. Pada daerah pantai umumnya di jumpai jenis Periophthalmus chrysospilos. Pada daerah mangrove lebih sering dijumpai jenis Periophthalmus gracilis. Pada daerah sungai lebih dominan jenis Boleophthalmus boddarti dan Periophthalmonodon schlosseri. Kata kunci: ikan gelodok, identifikasi, tipe habitat.

Abstract

X. granatum is one of mangrove plants that may exist in extreme environments. This plant contains secondary metabolites for further study. Complete Random Design (CRD) was used with 5 treatment of light intensity (0%, 25%, 50%, 75% and 100%) of X. granatum seedlings. Results showed that 100% shade (0% light intensity) provided the highest growth response, but does not necessarily provided optimum growth response. The total content of polyisoprenoid in 0% shade was of 0,153 ml little bit higher than 75% of 0.144 ml. TLC analysis of the results showed that the concentrations of dolichol in treatment 0% shade was higher in  the root and the leaves of X. granatum seedlings compared to 75% shade treatment . Keywords: Mangrove, Non Saponifiable Lipids ( NSL ), Polyisoprenoid, Xylocarpus granatum.

Abstract

Deteriorating of mangrove cause many impacts it deteriorate happen because too many land clearing activities in mangrove for harber, public building, and fishponds. Dergadation of mangrove should immediately resolved, one of them is with rehabilitation in mangrove areas use fungi which are expected to increase growth of plants and can be survive. The research was conducted from June 2014 until January 2015 using Completely Randomized design (CRD). There are 3 types of fungi treatment with five replications. Fungi that use are  A.flavus, A.terreus, and T.harzianum. Application of T. harzianum gave the best result on seedling growth of Ceriops tagal spesies with an average height is 2.68 cm, a diameter is 0,226 cm, leaf area is 89.89 cm2, and total dry weight is 4.02 g. They are  compared with control seeds and the provision of other fungi.   Keywords: Ceriops tagal, fungi, rehabilitation, seedling.

Abstract

Mangroves has a special ability to adapt with extreme environmental conditions. This condition allows mangroves to produce secondary metabolites as chemical defenses for their sustainability. Polyisoprenoid is one of the secondary metabolites which unknown function. The purpose of this study is to analyze the growth of S. alba seedling in responsse to shade variations and salinity concentration and its influence on the concentration of long-chain polyisoprenoid. The research was conducted from August to December 2014 using Factorial Completely Randomized design with shade treatment of 0%, 25%, 50%, and 75% along with salinity levels of 0%, 1.5% and 3%. Analysis of non-saponifiable lipid content and polyisoprenoid was done by comparing the leaves and roots of S. alba seedlings in variation 0% shade and 3% with salinity variations and in 75% shade with 3% salinity. The results showed that growth of S. alba seedling was optimum variation of 0% shade and 3% salinity showing 100% growth, 2.6 cm height, 0.17 mm diameter, 0.113 g fresh weight root, 0, 08 g dry weight root, 0.15 g wet weight shoot, 0.05 g dry weight shoot, 4 leaves number and ratio shoot and roots was 0.59. Polyisoprenoid content obtained at 190,5 ml in leaves an 133,4 ml in roots from variation 0% shade and with 3% salinity but in 75% shade with 3% salinity at 185,2 ml in leaves and 231,9 ml in  roots. Polyisoprenoid may play an important role in adapting the availability light intensity, which polyisoprenoid concentration increased with reducing light intensity on S. alba seedlings.Keywords : Mangroves, S. alba, shade, salinity, polyisoprenoid

Abstract

Mangrove condition deteriorating lead to the quality and quantity of mangrove seedlings wane. To improve and get better mangrove seedlings, then the required rehabilitation of mangroves. One of the efforts is the use of various types of fungi that can enhance the growth of mangroves for the better. This research can provide information on the types of fungi are able to increase growth of seedling R mucronata. This study was conducted from June 2014 until January 2015 using a completely randomized design (CRD) with treatment application types of fungi and five replications. There are three types of fungi namely A. flavus applied,  A.terreus T. harzianum. Application of Trichoderma harzianum gave the best results on seedling growth parameters R. mucronata, with an average height of 15.48 cm, a diameter of 0.47 cm, 1375.43 cm2 leaf area, and total dry weight of 119.50 g higher than the average of control and another fungi.Keywords: Rhizophora mucronata,  Fungi,  Mangrove, Rehabilitation.

Abstract

Condition of mangrove area has been decreasing due to the degradation and conversion of mangrove for other land use. Therefore, it is necessary for rehabilitation on mangrove land. This study aimed to test the ability of various types fungi on a field scale then to compare the ability of fungi to increase the growth of mangroves and to establish a type of fungi that have a greater ability to promote the growth of mangroves.  B. gymnorrhiza seed was used with 4 treatments. The results showed a response Bruguiera gymnorrhiza seedlings treated with the fungi Aspergillus flavus applications, Aspergillus terreus, and Trichoderma harzianum effect on seedling growth. T. harzianum showed the best results compared to other fungi on all parameters of observation with an average height of 10,45 cm, an average diameter of 0,56 cm, average leaf area rat 104,87 cm2, and the total dry weight of 2, 65 g. All parameters observed fungal applications only affected on height growth and total dry weight significantly on B. gymnorrhiza seedlings.Keywords: Bruguiera gymnorrhiza, mangrove, rehabilitation, Trichoderma harzianum

Abstract

Mangrove forest is one of coastal ecosystems that have high productivity. Recently, mangrove damaged either directly or indirectly. Direct damage for example logging, timber harvesting, settlement construction and ponds manufacturing, ports and roads construction, and arrest biota in mangrove ecosystems. Furthermore, indrectly threat maybe caused by coastal dredging, disposal of waste and industrial waste in the sea and the coast, coastal and marine mining, and deforestation. As a result above-mentioned threat of degraded mangrove forests.   Therefore, it is needed for rehabilitation efforts. The research was conducted in September 2014 to January 2015 using a completely randomized design (CRD) with treatments of A. flavus, A. tereus and T. harzianum and with five replications. Results showed that different fungi treatment provided different growth response. The highest mean of height growth obtained from B. cylindrica  seedlings treated with A. tereus that was 7.29 cm. The largest diameter was obtained seed treated with T. harzianum by 0.42 cm. The highest value of dry weight obtained from seedlings treated with fungi A. tereus that was 1.74 g. The largest leaf area obtained from seedlings treated with fungus of T. harzianum, that was 402.23 cm2.Keywords: A. flavus, B. cylindrica , fungi, Mangrove, T. harzianum.
