Judul: Evaluasi Kecernaan Hay Hijauan Jagung Muda Umur 17 Hari sebagai Alternatif Sumber Hijauan untuk Pedet Hasil Penyapihan Dini
Abstrak: Hay of young corn forage age 17 day (hjm17) has a great potential as forage because of its high nutrient content, smooth teksture, and high production. This experiment used 9 post-weaning male calves (4-5 months) which weaned early with body weight 97.2 ± 10.14 kg. This experiment used completely randomized design with 3 treatments and 3 replications. The treatments were P1 (calf starter + 100% elephant grass/control), P2 (calf starter + 50% hay hjm17 + 50% elephant grass), and P3 (calf starter + 100% hay hjm17). Variables observed were dry matter digestibility, organic digestibility, fiber digestibility, acid digestible fiber (ADF) and neutral digestible fiber (NDF digestibility). The data were analyzed by analysis of variance. The results of this experiment showed that hay hjm17 did not show any significance effect on dry matter digestibility, organic digestibility, fiber digestibility, and neutral digestible fiber (NDF), but it give significance effect on ADF digestibility (P<0,05). The result of this research showed that hay hjm17 can be used as forage for early weaned calves especially as elephant grass subtituted on dry season and area with hay hjm17 potential. Key words: digestibility, early weaned calves, hay hjm17.

Judul: Production and Quality of Forage Maize Pertiwi 3 Varieties given Different Fertilizer Treatment and Harvesting Age in The Green Fodder System
Abstrak: Penelitian ini bertujuan mengevaluasi produksi dan kualitas jagung varietas Pertiwi 3 yang ditanam secara green fodder. Penelitian ini menggunakan rancangan acak kelompok faktorial yang terdiri dari 3 faktor nutrisi yaitu P1 (kontrol), P2 (larutan pupuk organik cair NASA), dan larutan anorganik P3 (AB Mix), dan 3 faktor umur panen yaitu T1 8 hari setelah tanam (HST), T2 12 HST dan T3 16 HST dengan 4 ulangan kelompok. Data dianalisis dengan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa terdapat pengaruh interaksi yang signifikan antara larutan hara dan umur panen. Pemberian larutan nutrisi AB Mix dan umur panen 16 HST meningkatkan tinggi tanaman, ketebalan akar dan biomassa segar hijauan secara nyata. Namun, aplikasi larutan nutrisi AB Mix tidak mempengaruhi kualitas hijauan jagung. Perlakuan pupuk anorganik AB Mix dan umur panen 16 HST menghasilkan kualitas jagung pakan hijau terbaik dengan bahan kering 14,77%, protein kasar 21,97% dan serat kasar 14,47%., The experiment aimed to evaluate the biomassa production and the quality of corn Pertiwi 3 Varieties given different fertilizer treatment and harvesting age. This study used factorial blok randomized composing of 3 nutrition factors, namely P1 (control), P2 (liquid organic fertilizer solution NASA), and P3 (anorganic AB mix solution), and 3 harvesting age factors, namely T1 8 day after sowing (das), T2 12 das and T3 16 das with 4 group replications. Data were analyzed with Analysis of Variance (ANOVA) and further followed by Duncan test. The results showed that there was a significant interaction effect between nutrietion solution and harvesting age. Application of AB mix nutrition solution and 16 das harvests significantly increased the height of the plants, root thickness and fresh biomass of green fodder. However, application of AB mix nutrition solution did not affect green fodderquality of corn. Anorganic fertilizer treatment AB mix and 16 das resulted in best green fodder corn quality with dry matter 14.77 %, a crude protein 21.97 % and crude fibers 14.47 %.

Judul: Karakterisasi Film SrTiO3 terhadap Variasi Pendadah RuO2 dan Kecepatan Putar dengan Metode Chemical Solution Deposition
Abstrak: Telah berhasil dibuat film SrTiO3 terhadap variasi konsentrasi pendadah RuO2 0%, 2%, 4%, dan 6% dan variasi kecepatan putar (rpm) diatas substrat silikon tipe-p (100), menggunakan metode Chemical Solution Deposi dengan bantuan spin coating berkecepatan 6000 rpm, 8000 rpm, dan 10000 rpm selama 30 detik dalam kelarutan 2 M. Film diannealing pada suhu 850 oC selama 8 jam dengan kenaikan suhu 1.67 oC/menit. Sampel dikarakterisasi menggunakan Spektrofotometer Ocean Optics USB4000, XRD, SEM, dan EDX, sehingga didapatkan ketebalan film 1.247 μm sampai 2.599 μm dengan energi bandgap sebesar 3.03 eV sampai 3.255 eV. Diperoleh nilai parameter kisi a sebesar 3.4782221 Å sampai 3.950636 Å, sehingga struktur kristalnya berbentuk kubus (α = β = γ = 90o).
