ANALISIS IMPLEMENTASI KURIKULUM 2013 DI SMA NEGERI 3 REJANG LEBONG, BENGKULU

This study aimed at analyzing qualitatively the implementation of K13 curriculum which has long been applied in the state senior high school number 3 of Rejang Lebong. The data were garnered using observations and interviews for the sake of eliciting information to answer the proposed problem. The other technique considered important was documentation to see the curriculum-based depictions and loads in the existing documents. After the data were gathered, the selection of data was undertaken in order to be displayed in findings; the data were analyzed and discussed; and they were concluded as the ultimate answer to the formulated problem. The present study drew a conclusion that the implementation of k13 curriculum ran well although some obstacles were faced such as learning facilities. The entire school’s community seemed to be committed to carry out the mandate of this national educational system’s law such as training for teachers’ competence, doing the duties of making lesson plans in the form of RPP and syllabi, providing a monthly report concerning the implementation of learning by teachers, and carrying out evaluations alongside giving guidance for teachers’ performances.

Inter-Accession Variation for Salt Tolerance in Proso Millet Panicum Miliaceum L.

Exploration of genetic variation in natural population with subsequent selection for improved salt tolerance is an excellent strategy to utilize salt affected soils. In order to assess inter-accesional variation for salt tolerance in Panicum miliaceum L., 18 local accessions were screened at germination, seedling (0, 60, 120 and 180 mM NaCl)and adult stage by growing at varying levels of NaCl. In a set of 18 accessions of Panicum miliaceum accessions 008208, 008210 and 008215 were tolerant and accession 008216 salt sensitive at both these initial growth stages, while accession 008230 was tolerant at germination stage but intermediate at the seedling stage. Although the degree of salt tolerance in some accessions of P. miliaceum maintained at two early growth stages, it varied in most of the accessions at both initial growth stages. Moreover, none out of 18 available accessions of P. miliaceum was able to maintain the degree of salt tolerance consistently at all growth stages, i.e. germination, seedling and adult vegetative growth stages. Net CO 2 assimilation rate (A) was positively correlated with salt tolerance in terms of growth and yield. From the data for gas exchange attributes, photosynthetic pigments, ion accumulation it is suggested that lower transpiration rate (E) and higher water use efficiency (WUE measured as A/E) in salt tolerant P. miliaceum accessions seems to be responsible for lower rates of uptake and accumulation of Na + in photosynthetic tissues that resulted in higher photosynthetic efficiency and hence salt tolerance. Moreover, from the data for correlations among each of A, g s , C i and E in P. miliaceum accessions it is suggested that salt-induced decline in photosynthetic efficiencywas found to be associated partially with stomatal factors. Generally, P. miliaceum accessions having better plant water status and lower Na + accumulation had lower oxidative damage and higher photosynthetic capacity. It was suggested that extent of Na + accumulation in the leaves determine the activities of antioxidant enzymes and photosynthetic capacity, indicating that ROS detoxification is only one of the important components salt-stress tolerance. Taken overall, considerable intra-specific variation for salt tolerance was observed in P. miliaceum accessions. Reduction in growth and grain yield of all accessions were due to high accumulation of Na + and Cl - , low RWC, and low photosynthetic rate. Of these physiological attributes, photosynthetic rate, chlorophyll ‘a’, Na + exclusion and K + /Na + ratio were considered as potential physiological indicators for salt tolerance in P. miliaceum can be used in breeding programs meant for improving salt tolerance
