AbstrakAlga merupakan mikroorganisme fotosintesis yang tidak memiliki tubuh sejati dengan distribusi lingkungan yang sangat luas dan memiliki banyak fungsi, salah satunya sebagai indikator perubahan lingkungan. Wilayah Cekungan Bandung telah dilakukan penelitian dari beberapa aspek. Akan tetapi, penelitian terutama dari aspek alga yang memperlihatkan perubahan lingkungan belum dilakukan pada daerah tersebut. Penelitian ini dilakukan untuk melihat bagaimana perubahan lingkungan dari endapan sag pond bekas Danau Bandung pada wilayah Cekungan Bandung menggunakan keberagaman alga dan ukuran butir sedimen. Metode asam dilakukan untuk memisahkan alga dari endapan, serta deskripsi batuan dilakukan untuk melihat ukuran butir endapan pada lokasi penelitian. Analisis data dan pemodelan dilakukan dengan mengelompokkan alga sesuai dengan kondisi habitatnya yang terbagi menjadi kelompok Pinnularia, Euglena, Acrinastrum dan Dinobryon. Hasil penelitian menunjukkan bahwa lokasi penelitian mengalami empat kali perubahan lingkungan yang dibagi kedalam zona-zona dan subzona. Setiap zona tersebut diawali dengan kondisi air tercemar yang ditandai oleh peningkatan kelompok Euglena dan ukuran butir halus dari sedimen. Sedangkan pada bagian akhir, perairan memperlihatkan kondisi air normal yang ditunjukkan dengan peningkatan kelompok Pinnularia dan ukuran butir sedimen yang menjadi lebih kasar.AbstractAlgae is known as a photosynthetic microorganism that donâ€™t have a true body with very broad distributions of the environment. Algae have a lot of functions, one of which is an indicator of environmental change. The Bandung Basin area has been researched from several aspects. However, research especially from the algae aspect that shows environmental changes, has not been carried out in this area. This research was conducted to see how the environmental changes of Lake Bandung sag pond deposits in the Bandung Basin by using algae diversity and grain size deposits. The acetolysis method is carried out to see algae content in the sediment, and rock description is carried out to see the grain size of the sediment in the study area. Furthermore, data analysis and modeling were conducted by grouping algae according to environmental conditions which are divided into Pinnularia group, Euglena group, and other groups. The result showed that the study area occurred four times in environmental changes which were divided into zones and subzones. Each zone initially had polluted water conditions characterized by an increase in Euglena groups and the fine grain size of sediment. While in the end, the waters showed normal water conditions characterized by an increase in Pinnularia group and the grain size of the sediment became coarser.

The research area is located in the Muara Teweh, North Barito, Central Kalimantan. The cocking coal deposits are well known as they were produced from this area. Upper part of Tanjung Formation is target coal production. The study objectives are to analyze paleoenvironment and to determine the relative age of coal deposits based on palynological data. Preparing palinological analysis used standard procedure by hydrofluoric acid method.Palynomorphs data grouped into six types of ecology, and the sequence is as follows ; fresh water and lowland (41,75 %), brackish water swamp (30,10%), Peat and freshwater swamp (17,96%), marine element (7,77 %), back mangrove (1,46%) and upland element (0,97). Palmae pollen is very dominant, especially from freshwater and peat swamp that grow around coastal area i.e. Dicolcopollis, Proxapertites cursus, Proxapertites operculatus, Longapertites and Palmaepollenites kutchensis. Although marine fossil found, but the frequency less than one percent, that was the evidence of influence sea water to swamp area. The palynomorphs indicate the coal sedimented at upper delta plain. Fossil index of relative age consist of Proxapertites cursus, Proxapertites operculatus, Magnastriatites howardi Verrucatosporites usmensis, Retistephanocolpites , and Ixonantes type which refer to Late Eocene.

The central role of Mahakam River in the construction of Mahakam Delta is to supply sediment from terrestrial to the river mouth. The river upstream comes from Mount Camaru and the downstream part terminate at Makasar Strait. The surrounding area of the river is overgrown by wet tropical flora that produces pollen. The existence pollen in river sediments as an indicator that sediment came from terrestrial, and foraminifera as an indicator that sediment came from marine. The ratio changes of pollen to foraminifera show that there were differences of sediment source supply. The study was conducted at the river mouth. A shallow core, 200 cm depth, composed of sand and mud and sandy mud, from it taken vertically 11 samples to be analyzed pollen and foraminifera. Sample preparation was using standard methods acetolysis. Meanwhile, sample preparation of foraminifera using Hydrogen Peroxide method. Pollen found at all samples, but foraminifera only found in 8 samples. The data indicating that sedimentation process in the mouth of a river not only gets sediment supplies from terrestrial but also from marine. The quantity of pollen and foraminifera varies vertically. The frequency of pollen much higher than foraminifera that indicates of source sediments dominance came from terrestrial which carried by Mahakam river current. Sonneratia caseolaris pollen continuously found in all samples. Stictogongylus vandiemensis is species foraminifera the most common that followed by Ramulina confossa, both of them come from the sea particularly from the shallow sea.

Proxapertites have become one of the most significant indicators of ancient rock in Indonesia. Walat Formation is one of the oldest rocks exposed in Sukabumi, West Java, Indonesia. These Proxapertites have not been described in detail about their characteristics in previous studies, especially on Walat Formation. Therefore, knowing the characteristics of Proxapertites becomes interesting, especially in Walat Formation, which can be a reference for the characteristics of the late Eocene Proxapertites (37.8 - 33.9 million) in Indonesia. Acetolysis method was carried out for the preparation of pollen and spores; description and determination were carried out to see the characteristics of Proxapertites that present in Walat Formation. Result, there are three types of Proxapertites. Proxapertites operculatus have sizes 23 – 86 µ with average 40.5 (P) and 51.1 (E) µ, index PE 0,43 - 1, Peroblate – Subspheroidal – Oblate Spheroidal, Fine-Reticulate ornamentation, and Asymmetric Monosulcate aperture. Proxapertites cursus have sizes 23 – 86 µ with average 39.8 (P) and 49.8 (E) µ, index PE 0.51 - 1, Oblate – Subspheroidal – Oblate Spheroidal, Reticulate ornamentation, and Asymmetric Monosulcate aperture. Whereas Proxapertites psilatus have sizes 29 – 75 µ with average 42.3 (P) and 52.5 (E) µ, index PE 0.58 - 1, Oblate – Subspheroidal – Oblate Spheroidal, Psilate ornamentation, and Asymmetric Monosulcate aperture. These three Proxapertites can be distinguished by their type of ornamentation. Meanwhile, other aspects have similar characteristics and are affected by the appearance of individual pollen on the slide during preparation.

Fungsi geopark salah stunya adalah konservasi bentang alam di suatu kawasan meliputi konservasi sumber genetik. Hutan mangrove yang berada disekitar Pantai Cikadal sebelum mengalami kerusakan merupakan kawasan hutan dengan tingkat heterogenitas tinggi (data BKSDA). Tumbuhan mangrove mengalami kerusakan parah akibat penebangan berlebihan oleh masyarakat sekitar. Tujuan penelitian untuk menganalisis struktur tumbuhan mangrove sebelum mengalami kerusakan berdasarkan data polen. Sampel daimbil pada lima titik di lahan mangrove pada kedalaman 50 cm. Preparasi sampel menggunakan metode standar asam hiroflorid. Kegiatan reboisasi mangrove di mulai tahun 2012 yang melibatkan masyarakat pecinta lingkungan (POKMASI, Kelompok Masyarakat Konservasi). Reboisasi masih sangat terbatas dikarenakan ketersediaan bibit dari perhutani. Spesies yang ditanam adalah Rhizhopora mucronata dan Rhizophora apiculata. Program reboisasi perlu ditingkatkan untuk mencapai hasil yanng optimal. Hasil penelitian polen dari kedalaman 50 cm yang diambil dari kawasan mangrove menunjukkan perbedaan yang sangat signifikan dalam struktur jenis tumbuhan mangrove. Ditemukan delapan belas jenis tumbuhan mangrove yang pernah tumbuh di kawasan tesebut, duabelas jenis diantaranya punah. Avicennia yang pada saat ini eksistensinya terancam dan sangat sulit ditemukan, pernah menjadi tumbuhan utama pembentuk mangrove sebelum mengalami kerusakan. Sedikitnya ada lima jenis Avicennia dan dua jenis Rhizophora yang merupakan dua genus dominan pada saat itu.

Delta Kaligarang terletak di Utara Pesisir Semarang. Tujuan dari penelitian ini ialah untuk mengetahui dinamika lingkungan pengendapan yang terjadi di Delta Kaligarang, Semarang melalui analisis ukuran butir, material organik dan inorganik dari sembilan puluh contoh sampel. Hasil yang diperoleh menunjukkan adanya dua lingkungan pengendapan berdasarkan karakteristik sedimentologi (besar butir dan organik) yakni lingkungan energi relatif rendah (suspension load) dan lingkungan berarus turbulen (tidal). Selain itu, juga terdapat kenaikan nilai material organik dan inorganik, yang disertai adanya perubahan besar butir. Terlihat bahwa lapisan pada kedalaman 0-31 meter mengalami kenaikan nilai organik, seiring dengan besar butir yang berukuran silt. Hal tersebut berbeda dengan lapisan pada kedalaman 32-45 meter, di mana terdapat perselingan satuan batuan silt dan sand, serta nilai material organik turun.Kaligarang Delta is located in the North Semarang Coast. The objective of this research is to describe dynamic environmental changes in Kaligarang Delta based on grain size, organic and inorganic matters analyzes from ninety samples. The results indicated that two conditions occurred: low-energy-suspension-load environment and tidal (turbulent) environment. Furthermore, the increase of organic and inorganic matters coincides with the grain size distribution. At depth 0-31-meter, organic matter increased that coincident with silt grain size. At depth 32-45 meter the lithology shows interspersed of silt and sand.

Penduduk Kampung Pasir Angling sebgian besar sebagai peternak dan petani. Mereka membuat kandang sapi secara tradisional. Kualitas kandang belum memenuhi syarat kebersihan. Fases sapi belum dimanfaatkan secara optimal, mereka membuang fases ke sungai Cikapundung yang menjadi sumber pencemaran, dilain pihak air sungai Cikapundung adalah bahan baku air minum PDAM Kota Bandung. Peningkatan kandang tradisional menjadi kandang bersih dan ramah lingkungan adalah tujuan dari pengabdian kami. Telah dilakukan upgrade sebuah kandang sapi dari kandang tradisional berlantai kayu, menjadi kandang bersih berlantai plsester dilengkapi dengan saluran pembuangan dan bak tampungan feses. Uprage kandang mampu meningkatkan kebersihan susu, mengurangi ketergantungan terhadap pupuk buatan dan mengubah kebiasaan membuang limbah ternak ke Sungai Cikapundung menjadi bahan produktif pupuk Kascing yang ramah lingkungan
