Abstract

Fiddler crabs (Uca spp.) are distributed widely in tropical and subtropical areas in the world. They live in the sandy and muddy bay habitats of intertidal zone. This study aimed to find species abundance, microhabitat and population density of fiddler crabs in mangrove conservation area of Pantai Panjang, Bengkulu.  The sampling was conducted for three months started from December 2013 to February 2014. Sampling locations were decided purposively on the area consist of four microhabitats, i.e. sandy, muddy, muddy around decay plant roots and around mangrove roots. Samples of Uca were collected from 1x1 m of sixty quadrants.   The results found seven species of fiddler crabs i.e. U. perplexa, U. lactea, U. jocelynae, U. forcipata, U. triangularis, U. rosea, and U. dussumieri. They were distributed at four microhabitats. The microhabitats of U. perplexa, U. lactea, U. jocelynae, U. forcipata, U. triangularis, U. rosea, and U. dussumieri were around mangrove roots and sandy, around mangrove roots, muddy, muddy, muddy around decay plants, muddy and sandy areas, respectively. Among those species, U. perplexa was the most abundant population whereas U. dussumieri was the less one. Popolation density of fiddler crabs were U. perplexa  5.48  ind/m2, U. lactea 4.25 ind/m2, U. jocelynae , 1.47 ind/m2, U. forcipata 0.28 ind/m2,  U.triangularis 0.18 ind/m2,  U. rosea 2.17 ind/m2 and U. dussumieri 0.12 ind/m2.Key words: Mangrove, microhabitat, population, Uca spp.

Abstract

Trametes versicolor merupakan salah satu fungi pendegradasi kayu dari golongan white rot fungi yang memiliki kemampuan dalam menghasilkan enzim ekstraseluler, yaitu cellobiose dehydrogenase (CDH). Enzim CDH memiliki dua domain, yaitu domain flavin dan domain heme yang dihubungkan oleh 25 asam amino yang kaya akan serin dan treonin. Penelitian ini bertujuan mendeteksi CDH yang dihasilkan oleh T. versicolor baik secara kualitatif maupun kuantitatif. Deteksi CDH dilakukan melalui empat  tahap, yaitu: uji kualitatif enzim ekstraseluler, produksi CDH pada media cair, pengukuran aktivitas CDH menggunakan DCIP sebagai akseptor elektron dan selobiosa sebagai substrat, serta analisis bobot molekul CDH dengan elektroforesis SDS-Page. Hasil penelitian menunjukkan terbentuknya zona bening disekitar fungi setelah perlakuan congo red dan NaCl yang mengindikasikan bahwa T. versicolor menghasilkan enzim ekstraseluler. Produksi CDH dilakukan dengan menumbuhkan fungi di media YPD dan media minimal guna menginduksi produksi CDH. Pengukuran aktivitas enzim CDH belum berhasil dilakukan dan berdasarkan hasil SDS-PAGE, sebagian besar enzim CDH dari T. versicolor dihasilkan dalam bentuk domain flavin.  Kata kunci : Cellobiose dehydrogenase, SDS-Page, Trametes versicolor

Abstract

Sudah umum diakui bahwa biologi adalah dasar penguasaan dan pengembangan ilmu serta pemanfaatan teknologi pertanian, perkebunan, kehutanan, perikanan, kedokteran, kesehatan, lingkungan, dan disiplin ilmu-ilmu serta teknologi lain yang kegiatannya ditumpukan pada sumber daya alam hayati. Dalam beberapa dasawarsa terakhir kita menyaksikan bahwa biologi dan segenap cabang spesialisasi serta ranting-ranting superspesialisasinya maju dengan pesatnya, akan tetapi disiplin terapan yang lain juga tumbuh melesat dengan lebih cepat lagi karena dipacu oleh desakan kepentingan yang sangat bersifat antroposentris. Jika dulu tergelar jarak waktu panjang sampai belasan tahun antara temuan ilmiah potensi kemampuan jamur Penicillium notatum untuk menekan pertumbuhan bakteri (1929) dan penerapan luasnya sebagai obat suntik antibiotik penisilin (1944) yang sangat terkenal, sekarang hanya diperlukan waktu bulanan saja untuk dapat mengambil manfaat praktis sebuah pengungkapan spektakular bioteknologi.

Abstract

Uji provenan untuk memilih materi genetik surian yang akan dilibatkan dalam program pemuliaan telah dilakukan di Candiroto, Jawa Tengah dengan menguji 15 provenans dengan rincian 5 provenans dari Jawa Barat, 8 provenas dari Jawa Tengah dan 2 provenans dari Jawa Timur. Desain pengujian berbentuk square plot (5 x 5), 25 pohon setiap blok, 3 replikasi dengan jarak tanam 3 x 3m pada areal seluas 1,2 Ha. Pengamatan periodik dilakukan dengan melakukan pengukuran beberapa sifat pertumbuhan penting antara lain bentuk batang dan indeks volume kayu. Pemilihan kedua sifat tersebut berdasarkan peruntukan kayu surian adalah untuk bahan kayu pertukangan yang dipersyaratkan memiliki bentuk batang lurus, silindris dengan tinggi bebas cabang seoptimal mungkin, serta mampu menghasilkan volume kayu yang maksimal. Pengamatan pada umur 11 tahun terhadap bentuk batang dilakukan berdasarkan skor 1 – 5 sedangkan indeks volume batang dihitung tanpa dikalikan angka bentuk. Hasil pengamatan menunjukkan bahwa nilai rerata bentuk batang surian terdistribusi paling banyak pada pada rentang skor 2,03 – 4,21 dengan nilai rerata 3,2 yang mengindikasikan bentuk batang surian cenderung lurus mulai dari setengah tinggi bebas cabang hingga batang lurus setinggi bebas cabang. Pengamatan indeks volume seluruh provenans berada pada kisaran 0,11 - 0,33 m3 denga nilai rerata sebesar 0,23 m3. Analisis varian menunjukkan kedua sifat tersebut sangat dipengaruhi asal provenans. Hasil uji Duncan menunjukkan bahwa peringkat seluruh provenan untuk kedua sifat tidak selaras. Berdasarkan sifat bentuk batang dan indeks volume dari seluruh provenans yang diuji maka peluang menetapkan provenans terbaik untuk ditetapkan sebagai sumber materi genetik untuk pembangunan populasi pemuliaan telah dapat dilakukan karena data yang digunakan telah memenuhi setengah daur penebangan. Keterbatasan jumlah famili dan individu yang di plot uji provenans dapat dilengkapi dengan infusi atau penambahan materi genetik dari provenans terpilih tersebut dengan tetap mempertimbangkan area koleksi yang mewakili sebaran provenas dan kecukupan jumlah famili. Untuk mendapatkan panduan dalam infusi materi genetik maka diperlukan informasi keragaman genetik, sehingga koleksi materi genetik lanjutan yang akan dilakukan dapat lebih efektif.

The tofu liquid waste has a high organic matter content and potential for biogas production as an alternative fuel source through anaerobic process . In general , biogas contains 50-80 % methane , CO2 , H2S and water . The treatment of tofu liquid waste into biogas is beneficial for the owner tofu factory not only contribute to protecting the environment but also increase revenue by reducing fuel consumption in the tofu production. The purpose of thr program to follow up of the PKM - M ( Student Creativity Program Society) to provide an introduction the treatment of tofu liquid waste  into biogas as a fuel alternative and its application in the factory tofu owned by Mr. Jarwanto in Sumber Rejeki Village Rt 40 / Rw 7 Sidodadi District, Masaran Central Java . The methods of implementation through the simple design instrument with the principal part of digestive (digester) , raw material intake hole , out let of the products digestion sludge (slurry) , and the distribution pipes for biogas formed . In the tank digester is contain methane bacteria to decompose of organic matter and produce of biogas . The gas formed subsequently channeled into the pipes that are designed such that it can be directly utilized in such a way for example to the stove . The outcome this program to reduce the impact of environmental pollution as well as optimize the utilization of precisely and useful for the production of biogas that is easy and economical Keywords : tofu liquid waste , biogas , treatment , alternatif fuel
