Although Gyrinops versteegii has been domesticated by local community in Sragen Regency, the environmental factor and species which high compatibility with G. versteegii still not know yet. The objectives of this s have have n research were 1) o know which one of those vegetation communities that gives the best the diameter and height t growth of the domesticated G. versteegii 2) to know the environmental factors that influenced the growth of the , and diameter and height of the domesticated G. versteegii. Sampling was done systematically with a plot of size 20 20m × for trees, 10 10m for poles, and 5 5m for saplings with a total of 28 plots. SPSS Program version 22 was used for × × cluster, one-way anova, correlation, and multiple regression analysis. The results showed that for achieving the best G. versteegii growth, the G. versteegii should be planted under the community group which was dominated by Paraserianthes falcataria, T grandis, Gliricidia sepium and Eugenia aquea. Environmental factors affecting . , diameter growth of G. verteegii were organic carbon of the soil and the vegetation density. Meanwhile the environmental factors affecting the height growth of G. versteegii were temperature, light intensity, relative light intensity, organic carbon, C N ratio, P, Mg, air humidity, and clay content.
Respon fisiologis domba dipengaruhi oleh kondisi lingkungan seperti perubahan iklim dan pakan. Terbatasnya lahan pertanian dan padang penggembalaan menyebabkan sulitnya memperoleh rumput sebagai pakan sumber serat. Tujuan dari penelitian ini yaitu untuk mempelajari efek pemberian kangkung kering dan limbah tauge sebagai pakan pengganti rumput terhadap respon fisiologis domba ekor tipis jantan (umur kurang dari 1 tahun) dan palatabilitas limbah tauge dan kangkung kering sebagai pengganti rumput. Perlakuan pakan yang diberikan yaitu P0 (50% konsentrat+50% rumput), P1 (50% konsentrat+50% kangkung kering), and P2 (50% konsentrat+50% limbah tauge). Parameter yang diamati yaitu palatabilitas, suhu rektal, denyut jantung dan laju respirasi. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan 3 macam perlakuan pemberian pakan dan 4 ulangan. Data yang diperoleh dianalisis dengan ANOVA dan uji lanjut Tukey. Hasil penelitian menunjukan bahwa perlakuan pemberian pakan tidak berpengaruh nyata (P>0,05) terhadap suhu rektal, denyut jantung dan lju respirasi. Palatabilitas pakan yang paling baik adalah pakan P2 (50% konsentrat+50% limbah tauge). Kesimpulan dari penelitian ini, limbah tauge dan kangkung kering memiliki palatabilitas yang baik dan tidak berpengaruh nyata terhadap respon fisiologis domba ekor tipis sehingga dapat digunakan sebagai pengganti rumput.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
