    Full text link
    Permasalahan utama pada penelitian ini adalah rendahnya kemampuan siswa kelas IV SD Inpres 4 Kasimbar dalam menggunakan huruf kapital pada sebuah karangan. Untuk mengatasi masalah tersebut, peneliti melakukan penelitian tindakan kelas (PTK) dengan penerapan metode latihan. Penggunaan metode tersebut bertujuan untuk meningkatkan kemampuan siswa dalam menggunakan huruf kapital pada sebuah karangan di kelas IV SD Inpres 4 Kasimbar. Desain penelitian adalah penelitian tindakan kelas (PTK) dengan mengacu pada modifikasi spiral yang dikemukakan Kemmis dan Mc Taggart yang dilakukan dalam beberapa tahap, yaitu 1) perencanaan tindakan, 2) pelaksanaan tindakan, 3)observasi dan 4) refleksi. Metode yang digunakan adalah metode latihan. Subjek penelitian ini adalah siswa kelas IV yang berjumlah 17 orang siswa, 8 orang siswa laki-laki dan 9 orang siswa perempuan. Penelitian dilakukan dalam dua siklus. Hasil observasi kegiatan guru pada siklus I diperoleh nilai 78% berada dalam kategori cukup, pada siklus II diperoleh nilai 98% berada dalam kategori sangat baik. Untuk hasil observasi kegiatan siswa pada siklus I diperoleh nilai 76%, berada dalam kategori cukup, pada siklus II diperoleh nilai 96,00% berada dalam kategori sangat baik. Hasil belajar pada siklus I nilai ketuntasan belajar klasikal 70,59%. Pada siklus II nilai ketuntasan belajar klasikal 94,12%. Hal ini berarti pembelajaran pada siklus II telah memenuhi indikator keberhasilan dengan nilai rata-rata ketuntasan belajar klasikal memperoleh nilai minimal 85%, maka dapat disimpulkan bahwa penelitian dalam meningkatkan kemampuan menulis huruf kapital pada karangan melalui penerapan metode latihan dapat meningkatkan kemampuan siswa di kelas IV SD Inpres 4 Kasimbar

    Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan pupuk hijau cair azolla dan kihujan terhadap pertumbuhan dan fraksi serat (NDF dan ADF) rumput signal (Brachiaria decumbens).Penelitian menggunakan stek rumput signal, pupuk hijau cairazolla dan kihujan, serta EM4. Penelitian disusun berdasarkan rancangan acak lengkap dengan 3 perlakuan dan 5 kali ulangan.Perlakuan terdiri dari P0 (tanpa pupuk), P1 (pupuk azolla) dan P2 (pupuk kihujan).Parameter yang diamati adalah pertumbuhan tanaman meliputi tinggi tanaman, jumlah anakan, luas daun dan produksi bahan kering, fraksi serat (NDF dan ADF). Hasil penelitian menunjukkan bahwa penggunaan pupuk hijau cair azolla dan kihujan berpengaruh nyata (P0,05) terhadap jumlah anakan dan produksi bahan kering rumput signal. Pupuk hijauan cair azolla dan kihujan juga tidak berpengaruh nyata (P>0,05) terhadap kandungan NDF dan ADF rumput signal. Kesimpulan penelitian ini adalah pemberian pupuk hijau cair azolla dan kihujan mampu meningkatkan pertumbuhan rumput signal khususnya tinggi tanaman dan luas daun, dan cenderung meningkatkan jumlah anakan dan produksi bahan kering.Penggunaan pupuk hijau cair azolla dan kihujan pada taraf P1 dan P2 belum mampu menurunkan fraksi serat (NDF dan ADF) rumput signal

    The research has been carried out about determining the subsurface resistivity values by using the VLF method in waste disposal (TPA) Gampong Jawa Banda Aceh. Measurement target is for investigate allegations of contaminant substances are disposed by the public at these locations based on the response of the magnetic and electric fields. The tools used are the T-VLF device with two electrodes and using three stations, namely the transmitter JJF4 Japan, NWC Australia and UMS Moscow. Broad expanse of measurements on L1 and L2 is 200 m, L3 and L4 is 150 m. There are 74 measuring points with spacing of 10 m. The result of this experiment showed that the four layers can be divided into two layers with different resistivity values. The first layer at a depth of 0-15 m with apparent resistivity of 2-25 Ωm, allegedly at this layer contained the contaminant substances. The second layer at a depth of 15 m with apparent resistivity of 25-101 Ωm, in this layer are water-resistant coating that can withstand water into and out of the landfill

    Hybrid method for selection of the optimal process of leachate treatment in waste treatment and valorization plants or landfills

    “The final publication is available at Springer via http://dx.doi.org/10.1007/s10098-014-0834-4”Leachate from waste landfill or treatment plants is a very complex and highly contaminated liquid effluent. In its composition, it is found dissolved organic matter, inorganic salts, heavy metals, and other xenobiotic organic compounds, so it can be toxic, carcinogenic, and capable of inducing a potential risk to biota and humans. European law does not allow such leachate to leave the premises without being depolluted. There are many procedures that enable debugging, always combining different techniques. Choosing the best method to use in each case is a complex decision, as it depends on many tangible and intangible factors that must be weighed to achieve a balance between technical, cost, and environmental sustainability. It is presenting a hybrid method for choosing the optimal combination of techniques to apply in each case, by combining a multicriteria hierarchical analysis based on expert data obtained by the Delphi method with an analysis by the method of VIKOR to reach a consensus solution.Martín Utrillas, MG.; Reyes Medina, M.; Curiel Esparza, J.; Cantó Perelló, J.
