Judul: Keragaman Gen CSN3 Ekson 4 pada Kambing Peranakan Etawah di BPTU KDI-HPT Pelaihari Kalimantan Selatan
Abstrak: Etawah grade goat as one of Indonesian local animal genetic resources has advantages, one of which is its high milk yield. CSN3 gene is a member of casein fragment related to protein and casein contents. The aim of this study was to identify polymorphisms of CSN3 in Etawah grade goat from BPTU KDI-HPT Pelaihari, South Kalimantan using the PCR-RFLP method. Polymorphisms of CSN3 gene were identified of 115 blood samples using PstI restriction enzyme that cuts the fragment of CTGCA|G. CSN3 amplification resulted 407 bp which is located at exon 4 was performed with annealing temperature 60 °C for 20 seconds. The results of PCR-RFLP analysis indicated that the analyzed CSN3 gene of Etawah grade goat which have monomorphic F allele was 100%.

Judul: Identifikasi keragaman gen β-Kasein (CSN2) pada kambing peranakan etawah, saanen dan persilangannya dengan metode PCR-SSCP
Abstrak: Casein genetic polymorphisms are important and well known due to their effects on quantitative traits and properties of milk. β-kasein gene is directly related to the quality and properties of milk. A protocol for the rapid and simultaneous genotyping of β-kasein alleles was conducted by single strand conformational polymorphism polymerase chain reaction (SSCP-PCR) method in goat. Screening β-kasein gene variability in 3 dairy goat breeds was conducted for Etawah Grade (77 samples), Saanen (67 samples) and PESA (Crossbreed Etawah Grade with Saanen) (29 samples) in Bogor and Sukabumi. The objective of this research was to identify polymorphism of the β-kasein (CSN2) gene in dairy goat. This research found three alleles of the β-casein gene, ie CSN2*A, CSN2*C, dan CSN2*O. In most breeds, CSN2*O occurred in the lowest frequency. The identification of the CSN2 gene variability in the goat breeds indicated the highly of the A allele. The CSN2*A allele had a high frequency in Saanen in Cijeruk (0,66); Etawah Grade in Cariu (0,62); and PESA in Cariu (0,54). While the CSN2*C allele had a high frequency in PESA in Balitnak (0,83); Etawah Grade in Ciapus (0,48); and Saanen in Taurus (0.38). Based on the results of chi-square analysis, found that Saanen in Cariu and Taurus were not in Hardy-Weinberg equilibrium.

Judul: Pengukuran Engagement pada Permainan Orbital-X, Permainan Pertahanan Menara Sirkular
Abstrak: Jenis permainan pertahanan menara (tower defense) adalah sebuah gaya permainan yang memiliki tantangan tersendiri untuk menyusun sebuah strategi melawan musuh dengan menempatkan menara pertahanan yang tepat. Permainan dalam tugas akhir ini adalah permainan pertahanan menara yang memiliki konsep berbeda, yaitu dengan menaruh menara pertahanan di posisi tengah dan menara lainnya berputar sirkula. Sebelum permainan disebarkan, dibuat 2 buah kuesioner, yaitu kuesioner pra-permainan dan pasca permainan untuk mengukur engagement pemain. Kuesioner pra-permainan diberikan kepada 5 orang. Kemudian, mereka diberi waktu untuk memainkan Orbital-X selama satu minggu. Setelah itu, kelima responden diberikan kuesioner pasca permainan untuk mengukur engagement ketika bermain. Hasil pengukuran engagement pada aspek immersion, pemain sangat setuju dengan pertanyaan “Saya dapat dengan mudah menggunakan kontrol Orbital-X dan saya dapat menguasainya dengan cepat” dan pemain sangat tidak setuju dengan pertanyaan “Interaksi yang terjadi dalam dunia game yang saya mainkan sama halnya seperti saya berinteraksi di dunia nyata”.
