Judul: Pengaruh Wafer Ransum Komplit Limbah Tebu dan Penyimpanan terhadap Kualitas Sifat Fisik
Abstrak: Pucuk dan ampas tebu merupakan salah satu hasil ikutan yang dihasilkan oleh perkebunan tebu dan industri pengolahan gula, yang dapat dimanfaatkan sebagai salah satu sumber serat pada pakan ternak. Pucuk dan ampas tebu yang dihasilkan pada sepanjang musim penghujan dapat dimanfaatkan sebagai pakan alternatif saat musim kemarau. Penelitian ini bertujuan untuk mengetahui kualitas sifat fisik (kadar air, berat jenis, kerapatan, dan aktivitas air) wafer pucuk dan ampas tebu dengan penyimpanan selama enam minggu. Pembuatan wafer ransum komplit diharapkan dapat memudahkan dalam penyimpanan. Wafer komplit memiliki kualitas nutrisi yang cukup lengkap dan memudahkan dalam penanganan karena bentuknya padat kompak sehingga memudahkan dalam penyimpanan dan transportasi (Trisyulianti, 1998).

Judul: The Shelf Life of Complete Feed Wafers contains Corn Husks with Propionic Acid and Salt as Preservatives
Abstrak: Klobot jagung merupakan limbah pertanian yang dapat diolah menjadi wafer pakan komplit karena mengandung serat kasar yang tinggi. Wafer yang tidak langsung dikonsumsi ternak akan disimpan. Penyimpanan wafer juga perlu dilakukan untuk mempertahankan ketersediaan pakan terutama pada musim kemarau. Penelitian ini bertujuan mengevaluasi daya simpan dan kualitas wafer yang diberi asam propionat dan garam serta disimpan selama 6 minggu. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) faktorial (3 x 3) dengan 3 ulangan. Faktor L adalah lama penyimpanan dengan 3 taraf waktu (0, 3, 6) minggu. Faktor P adalah pengawet dengan 3 perlakuan (kontrol, asam propionat, garam). Parameter yang diuji meliputi organoleptik, kadar air, aktivitas air, serangan serangga, sebaran jamur, wafer durability index, dan biaya produksi. Terdapat interaksi antara lama penyimpanan dan penambahan pengawet pada parameter kadar air, aktivitas air, dan WDI (P<0,05). Lama waktu simpan wafer terbaik adalah 3 minggu dengan penambahan garam yang bernilai kadar air, aktivitas air, dan WDI berturut-turut (13,24 %; 0,636; 70,24 %)., Corn husks are agricultural waste that can be processed into complete feed wafers because they contain high amounts of crude fiber. Wafers that is not directly consumed by cattle will be stored. Wafers storage is also carried out to maintain feed availability, especially during the dry season. This study aimed to evaluate the shelf life and wafers quality added with propionic acid and salt and stored for 6 weeks. The research design used was a factorial Completely Randomized Design (CRD) (3 x 3) with 3 repetitions. The L factor was the storage time with 3 time levels (0, 3, 6) weeks. Factor P was a preservatives with 3 types (control, propionic acid, salt). Parameters tested include organoleptic, water content, water activity, insect attacks, mold distribution, wafer durability index (WDI), and production costs. There was an interaction between storage time and the addition of preservatives on the water content, water activity, and WDI (P<0,05). The best storage time for wafers was 3 weeks and the addition of salt with the values of water content, water activity, and WDI (13,24 %; 0,636; 70,24 %).

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.
