Judul: Konstruksi pustaka genom dan sekuensing genom total Kakao (Theobroma cacao L.)
Abstrak: The availability of reference genome sequence of cocoa (Theobroma cacao L.) allows the full potential of the other cocoa plant genetic variation to be read and used for breeding through whole genome reading by next generation sequencing (NGS). This study describes a modification of CTAB method for extracting genomic DNA contains high polysaccharides and polyphenols, genomic library construction and whole genome sequencing using methods by Illumina. High quality of genomic DNA indicated by integrity of the molecule have been produced. Genomic libraries have been constructed were 314-485 bp in size. Base generated reach 391.93 Gbp, with genome size reach 566.9 Mbp. The quality of readings by NGS high enough with 67.9-81.3% of reading has quality value above Q30. Error rate occurs at 0.20-1.14%. Genomic library have been constructed possesses good quality and the data from sequencing were ready for further analysis.

Judul: Konstruksi dan Analisis Kualitas Pustaka Genom Jagung (Zea mays (L.)) untuk Sekuensing Genom Total
Abstrak: Whole genome sequencing and analysis of the maize genome is one of the ways to accelerate the increase in corn breeding and to improve the understanding of the genetic and genomic information maize. The purpose of this study is to construct genomic libraries of four maize genotypes in Indonesia (Sp010BB-3-2- 2-1-B, LK2-45, PSG59-8 (early maturing) and LBP54-50 (pulut)) and analyze the quality of the results of genomic libraries total genome sequencing. Genomic library construction performed in vitro by attaching adapters to the ends of DNA fragments. Clasterization and sequencing of genomic library in this research were conducted by using cBOT claster generation and Next Generation Sequencing HiSeq2000. The amount of base produced during the sequencing process as many as 287.1 Gbp. Cluster genomic library generated with Q values above 30 scores ranged from 80.8 – 87.9%. Base reading error rate during the sequencing process was 0.32 – 0.51%. Over all sequencing results showed that quality of the genomic library cluster was belong to the ideal category.

Judul: Karakteristik lompatan hidrolik terhadap pelimpah terjunan pada saluran segi empat
Abstrak: Aliran dengan kecepatan tinggi dalam kondisi superkritis yang melintasi bangunan pelimpah, sebelum bergerak lebih jauh ke arah hilir saluran dimana bilangan Froude (F) lebih besar dari satu harus diubah menjadi aliran subkritis dimana bilangan Froudenya lebih kecil dari satu. Aliran yang meninggalkan kaki pelimpah merupakan aliran yang memiliki kandungan energi yang amat berarti sehingga dapat menimbulkan pengikisan yang besar. Pengubahan bilangan Froude dari kondisi superkritis ke subkritis dimaksudkan agar terjadi perubahan kandungan energi, sehingga aliran menjadi non erosive. Agar daya erosive aliran dapat berkurang, maka biasanya pada bagian hilir dari bangunan pelimpah dibuatkan suatu bangunan peredam energi. Erosi yang terjadi di hilir bangunan pelimpah dapat disebabkan dari keberadaan bangunan pelimpah itu sendiri, maupun bangunan peredam energi yang kurang tepat. Hal ini terutama menyangkut beberapa kejadian lompatan hidrolik yang timbul pada bangunan peredam energi tersebut.. Suatu metode yang efektif untuk menjamin bahwa lompatan hidrolik selalu terjadi pada daerah yang dilindungi, adalah dengan menggunakan bangunan peredam energi yang terdiri dari beberapa tipe dengan..dst
