Judul: Effective water harvesting for soil moisture Management on upland farming
Abstrak: Air termasuk faktor produksi yang vital bagi tanaman sehingga untuk mencapai produksi tanaman yang optimal harus dijamin penyediaan airnya. Pada usahatani lahan kering, pengelolaan dan penyediaan air tergantung waktu dan curah hujan. Distribusi hujan yang tidak menentu dan tidak merata sepanjang tahun merupakan kendala dalam perencanaan dan pengembangan usahatani lahan kering. Air hujan yang jatuh di areal lahan kering harus dikelola agar semaksimal mungkin dapat dimanfaatkan oleh tanaman yang ada di permukaan lahan tersebut. Bagian air hujan yang mengalir di permukaan tanah (runoff) harus dikendalikan dan dikelola agar lebih banyak yang masuk ke dalam tanah.

Abstrak: Kekurangan air merupakan faktor utama penurunan produksi dan kegagalan panen di lahan kering. Irigasi dengan air tanah atau air permukaan pada musim kemarau di lahan kering Lampung dpat meningkatkan produksi palawija dan hortikultura, indeks pertanamanan dari 200 menjadi 300 % serta pendapatan petani, namun masih terjadi pemborosan air irigasi sebanyak 10,5 mm/hari., Innadequate irrigation water is the main factor causing low productivity of the upland agriculture in Indonesia. Water supplement through various methods of irrigation practices gave significant increase to almost all of productivity. On the other hand, the water use efficiency (WUE) under the conventional floading system, is generally low.

Judul: Mitochondrial DNA Gene Organization and Phylogenetic Relationship of Naja siamensis
Abstrak: Naja siamensis is one of Asiatic cobra in the Family of Elapidae, known as a cryptic snake. It has many morphological variations that lead to misidentification. Misidentification can cause the wrong concept in developing antivenom types due to high snakebite cases occur in Thailand. Thus, an accurate species identification using a molecular approach is crucially required. Mitochondrial DNA has been used widely in snake molecular studies. These studies were aimed to determine the arrangement of the N. siamensis partial mitochondrial genes using reptile-oriented primers and to reveal the phylogenetic relationship among other species of Asian cobra. DNA extraction was carried out based on the standard DNA salting-out protocol and was conducted by bioinformatics analysis using BLASTn and MEGA 6 software. Gene annotation was performed against N. kaouthia complete genome. A total of 3121 bp of N. siamensis mtDNA genes were sequenced consisting of partial of six regions: 16S rRNA, ND1, tRNA-Ile, CRII region, tRNA-Leu, tRNA-Gln, and COI genes. The mtDNA gene organization of N. siamensis was predicted to has a similar pattern with the common Elapidae mtDNA gene organization. This study showed that there is a monophyletic form in Naja genus and N. kaouthia is the closest species with N. siamensis based on partial 16S rRNA and ND1 gene.
