Abstract

Ekosistem Mangrove merupakan ekosistem unik di pesisir sebagai pelindung daratan baik pelindung dari abrasi, intrusi dan sebagai habitat berbagai macam spesies. Besarnya fungsi mangrove ini akan sangat disayangkan ketika terjadi kerusakan karena akan berdampak ke berbagai aspek seperti matinya spesies, berubahnya garis pantai karena abrasi, masuknya air asin ke air tanah dan lain sebagainya sehingga perlunya pemeliharaan ekosistem ini. Pemeliharaan ini perlu dilakukan dengan pengenalan kondisi kawasan ini sehingga tindakan yang akan dilakukan lebih tepat. Tujuan penelitian ini adalah untuk mengenali kondisi ekosistem mangrove dan lingkungannya antara lain ancaman, kerentanan dan kerusakan yang bisa terjadi. Metode penelitian ini menggunakan analisis kualitatif semi-kuantitatif dengan statistik sederhana.. Pengambilan data dilakukan dengan analisis data sekunder dan observasi lapangan. Data yang diperoleh dianalisis menggunakan indeks ancaman gelombang terhadap ekosistem mangrove meliputi tinggi gelombang, arus, bentuk garis pantai dan ada tidaknya karang penghalang. Indikator tersebut merupakan indikator yang memperkuat besarnya energi gelombang. Kemudian mengguanakan indeks kerentanan mangrove dari gelombang meliputi luasnya vegetasi mangrove, zonasi mangrove dan fungsi hutan mangrove. Indikator tersebut akan memperkuat kondisi kerentanan mangrove dari gelombang. Selanjutnya tingkat kerusakaan menggunakan persamaan bencana, dimana tingkat ancaman dan kerentanan saling menguatkan terhadap kerusakan. Hasil analisis setiap indikator diklasifikasikan ke dalam 3 kelas menurut Rumus Sturgess, sedangkan tingkat kerusakan terhadap gelombang dikelaskan menurut matrik Peraturan KA BNPB No 02 Tahun 2012 yang dimodifikasi. Hasil penelitian antara lain (1) Ancaman gelombang terhadap ekosistem mangrove di Kawasan Konservasi Pulau Dua pada tingkat sedang (2) Kerentanan ekosistem mangrove terhadap gelombang di Kawasan Konservasi Pulau Dua pada tingkat sedang (3) Berdasarkan kondisi ancaman dan kerentanan maka dapat dilihat tingkat kerusakan pada kelas sedang. Dengan pengenalan kondisi ini diharapkan dapat menjadi pedoman bagi pemerintah maupun masyarakat untuk bertindak sebagai upaya pengantisipasian dan pengurangan kerusakan ekosistem mangrove dikarenakan gelombang.Keywords: ancaman, kerentanan, mangrove

Abstract

Vitamin E  ditemukan oleh Evans dan Bishop pada tahun 1922 sebagai nutrisi penting dalam fungsi reproduksi mamalia. Kemudian ditemukan kembali pada tahun 1950 oleh Klaus Schwarz dalam konteks sistem antioksidan  seluler (bersama asam amino dan selenium). Vitamin E yang meliputi tokoferol dan tokotrienol, merupakan molekul larut lemak yang memainkan peran penting dalam kesehatan mamalia, namun  hingga saat ini, pemahaman mengenai mekanisme  kerja dan fungsi hayatinya masih terbatas. Vitamin E hanya disintesis oleh organisme fotosintetik, salah satunya tumbuhan hijau. Kajian ilmiah ini mengupas fungsi  hayati  vitamin E  pada tumbuhan serta perannya pada  mamalia  (meliputi  peran baru  di luar antioksidan),  didasarkan pada aspek ekofisiologis.  Vitamin E  pada tumbuhan diketahui  memiliki peran sebagai pelindung tilakoid dari cekaman oksidatif, serta sebagai antioksidan dalam respon pertahanan fotosintesis. Hal ini serupa dengan peran pada hewan, bahwa vitamin E mencegah terjadinya penyakit kronis, terutama yang terkait komponen cekaman oksidatif: penyakit jantung, aterosklerosis, dan kanker. Melalui kajian ilmiah secara komprehensif dan mendalam ini, ditemukan beberapa fungsi vitamin E di luar fungsi spesifiknya sebagai antioksidan pada tumbuhan maupun mamalia, terutama peran penting yang ditemukan pada tokotrienol.  Vitamin E  mencegah peroksidasi lipid selama masa dormansi benih, perkecambahan, dan perkembangan awal benih  (pada tumbuhan), memiliki peran dalam ‘cell signaling’, daya proteksi DNA, lemak, protein, dan berperan dalam respon imun  (pada mamalia).   Tokotrienol, sebagai salah satu jenis vitamin E, perlu mendapatkan perhatian lebih karena memiliki fungsi anti-oksidatif, anti-hiperkolesterolemik, anti-angiogenik, dan neuroprotektif yang berbeda dengan tokoferol. Penelitian tambahan diperlukan untuk menentukan situs intraseluler spesifik yang mempengaruhi fungsi tokotrienol untuk sepenuhnya memahami mekanisme efek anti-kanker dan apoptosis. Selain itu, nilai potensi senyawa ini sebagai agen kemoterapi dalam pencegahan dan pengobatan berbagai kanker perlu diteliti lebih lanjut.  Kata kunci: Vitamin E, Fungsi Hayati, Tumbuhan, Mamalia

Abstract

Black rice (Oryza sativa L.) is one of germ plasm where there are many found in Indonesia. The popularity of black rice growing in line with public awareness for consuming a functional food. But the scientific study of black rice germ plasm in Indonesia still classified as low, especially the scientific study of the molecular genetik diversity. Information of molecular genetik diversity adequately on black rice germ plasm is one of the cornerstone for the development of action strategies for conservation the varieties of black rice in Indonesia in a sustainable way. The scientific study which is expected to be implemented in the form of research on black rice molecular genetik diversity is an approach of DNA barcode. Most of the genes that utilized as DNA barcode on plants is on chloroplasts DNA (cpDNA). cpDNA having the benefit characteristics for genetik diversity study compared with nuclei DNA (nDNA ) and mitochondria mtDNA. Characteristic of these is (1) the cpDNA genome have a small size and stable structure, (2) More conservative with lower average nucleotide substitution and (3) no recombination and uniparental heritable. This article discussed a potential DNA sequences of nucleotides from chloroplast DNA to give information on the genetik diversity of black rice, namely rbcL gene. Until now, NCBI database collected 143 partial sequence of rbcL gene. The number of partial sequence that has been collected is using as comparation facilitate to investigation the genetik diversity of Indonesia black rice. In the future, DNA barcode os expected to be implemented in the research.Keywords: genetik diversity, DNA barcode,rbcL gene,Indonesian local black rice

Abstract

Globalization and the development of science and technology causehuman needs increase. This has an effect on land use, especially in watershed areas. Serayu is one of watershed in Central Java which is have problems related to land use, which occurs in the upper of the watershed.Agricultural Intensification, deforestation, an increase in population are factors that drives land use change in the upper of Serayuwatershed.Utilization of watershed areas that ignore spatial rules causes pollution and land degradation. That condition happened and this makes the Serayuwatershed one of the priority watersheds for rehabilitation in Indonesia.Remote Sensing (RS) and Geographic Information Systems (GIS) are tools that used to analyze land use changes that occurred in 2009-2019. Land use classification is derived from the interpretation of Sentinel Image 2 and land use maps in 2009. Land use is classified into six classes; water bodies (rivers, lakes, ponds), built-up areas, shrubs, forests, agriculture (rice fields, fields), empty land.
