Postgraduate Program of Faculty of Animal Science UGM held a Public Lecture “Application of R-Statistical Software in Research Data Analysis in the Field of Animal Nutrition.” The lecture was held on Wednesday, 17 March 2021. Ahmad Sofyan, S.Pt., M.Sc., Ph.D. from the Indonesian Institute of Sciences or Lembaga Ilmu Pengetahuan Indonesia (LIPI), was the speaker of the public lecture, guided by the moderator Dr. Ir. Chusnul Hanim, M.Sc., IPM., ASEAN Eng., a lecturer at the Faculty of Animal Science UGM.
In his lecture, Ahmad Soyfan conveyed program introduction, problematic experiments, experimental design, data analysis (ANOVA and ANCOVA), and further information. Participants needed to analyze several case studies and provided usable research designs. The speaker also conveyed the research systematics so the research could be published, included several stages such as designing experiments, collecting and analyzing data, writing or drafting and proofing English, submitting or selecting journals, and journals being accepted or published.
“The experimental design is different between homogeneous and heterogeneous samples. For example, a homogeneous sample with one treatment factor can use a rancangan acak lengkap (RAL) or a completely randomized design (CRD). A heterogeneous sample consists of a single block and a double block. In one treatment factor, for a single block, uses a rancangan acak kelompok (RAK) or a completely randomized block design (RBD). The stage for a double block uses bujur sangkar latin (BSL) or a Latin Square Design (LSD),” said Ahmad Sofyan. Related materials and recommendations for journal publication were explained by the speaker.
