Abstract

Tujuan penelitian ini adalah mengetahui dinamika Nipah (Nypa fruticans Wurmb.) di muara Banjir Kanal Timur Semarang berdasarkan bukti polennya. Sampel sedimen diambil pada bulan Maret 2014 dengan pengeboran menggunakan bor tangan berdiameter 4 cm sedalam 2 m pada titik koordinat pengeboran: 06° 56’ 26.9” S dan 110° 26’ 41.9” E. Sampel sedimen dipotong tiap 5 cm dan dibuat preparat mikroskopis dengan metode Asetolisis. Berdasarkan pengamatan didapatkan hasil bahwa telah terjadi dinamika Nipah (Nypa fruticans Wurmb.) berdasarkan kehadiran polennya pada kedalaman yang berbeda. Polen Nipah ditemukan mulai pada sampel yang terletak pada kedalaman 186 cm (KS200-4), dan kehadiran polen Nipah terakhir di sedimen muara Banjir Kanal Timur Semarang adalah pada sedimen yang terletak pada kedalaman 12 cm dari permukaan (KS50-39) dan tidak ditemukan lagi pada sedimen di atasnya. Kondisi ini berkorelasi keadaan terkini dengan tidak ditemukannya komunitas Nipah di sekitar area muara Banjir Kanal Timur Semarang. Kata kunci: Nipah; polen; asetolisis; Banjir Kanal Timur

Abstract

Thirty sediment samples had been taken from the Tapak Formation of Kedung Randu areas, Banyumas, to reconstruct the diversity of mangrove flora from this area the past. This samples were processed for palynological slides used standard palynology preparation method. The microscopic identification of palynomorphs were done to identify taxa of paleoflora. Fifty-six types of pollen and spores fossils had been identified and 22 types were mangrove pollen-spores fossils. This fossils could be grouped into major mangrove (Zonocostites ramonae/Rhizophora type, Spinizonocolpites echinatus/Nypa fruticans, Florschuetzia levipoli/Soneratia caseolaris and Avicennia type); group of minor mangrove (Retitricolporites sp./Excoecaria sp., Discoidites novaguenensis/Brownlowia type, Camptostemon and Acrostichum aureum), and a group of plant associations (Retitricolporites equatoralis/Calophyllum type, Dicolpopollis sp./Calamus type, Racemonocolpites sp./Oncosperma, Marginipollis concinus/Barringtonia, Pandaniidites sp. /Pandanus, Terminalia catappa, Ilexpollenites sp./Ilex, Stellatopollis sp./Croton type, Acanthaceae type, Cyperaceaepollis/Cyperaceae, Podocarpidites/Podocarpus, Aglaia type, Haloragacidites/ Casuarina and Verrucatosporites usmensis/Stenochlaena palustris. Stenochlaeniidites papuanus and Podocarpus imbricatus were found in the samples. Tapak Formation was included in the last section of the Podocarpus imbricatus/Dacrycarpidites australiensis Zone of Java Palynological Zonation, and this formation was in the age of Late Pliocene towards Pleistocene. Key word: Tapak Formation; major-minor-plant associations of mangrove; palynological zonation

Abstract

The Marsh of Jombor Klaten is a natural swamp that was once small swamps surrounded by villages and hills located in the lower mainland and serves to hold rainwater. Environmental has changed from the lowlands into the aquatic environmentand the more widespread the diversity of types of flora around the Swamp Jombor has been changed.The diversity of types of flora can be known through the morphology of the pollen and spores. The purpose of this research is to know the diversity of plant species based on morphology of pollen and spores found in Swamp sediment Jombor. Sampling is done by drilling sedimentary soil clays Swamp Jombor on three points with the first location code RWJ (3) at a depth of 2 m situated around the keramba, the second code RWJ (4) at a depth of 1.5 m, and third code RWJ (5) at a depth of 0.35 m located around the inlet.The sample preparation using method asetolisis, then morphological characteristics observed pollen and spores. Calculated the number of each type of pollen and spores.The data obtained were analyzed using pollen and spore morphology of description. The data obtained were analyzed using pollen morphology characteristics and description of the spores found in the swamp Jombor. The results showed that the morphology of the pollen and spores found in Swamp sediment Jombor has a variation of shapes and sizes. The flora type obtained from the sediments Swamp Jombor as much as 28 type, including 8 typearboreal pollen (AP), 9 typenon arboreal pollen (NAP), and 11 type of spores. Types of flora that dominates is the NAP family Gramineae (80,10%) which indicates the plant a tree instead of in the form of shrubs or herbaceous were more developed in marsh of Jomborenvironment. Keywords: Jombor, morphology, pollen, spore, diversity.
