Respon Morfo-Fisiologis Cabai Rawit (Capsicum frutescens L.) terhadap Genangan Air dan Pemberian Bakteri Rhizosfer Leguminosae
No full textCayenne pepper is known to be susceptible to various types of flooding by showing various negative responses. This study seeks to ascertain the influence of PGPR on the adverse effects of floods on cayenne pepper as a means to mitigate farmer losses. The study used a completely randomized design on cayenne pepper which was given treatments in the form of control without PGPR (K(-)), control with PGPR (K(+)), flooding treatment for 2 days with PGPR 7 days later (P(+)) and without PGPR (P(-)) each with 10 reps. The two-way ANOVA test reflected that flooding had a significant effect on the response of plant height increase, petiole curvature angle, and wilting. In contrast, PGPR application had a significant effect on plant height increase and number of branches. The interaction of flooding and PGPR application significantly affects the increase in plant height but not the number of leaves, the number of branches, the angle of curvature of the petiole, and wilting. It was concluded that the application of PGPR can reduce the adverse effects of flooding on cayenne pepper farming.Cabai rawit diketahui rentan terhadap berbagai jenis banjir dengan menunjukkan berbagai respon negatif. Penelitian ini bertujuan untuk mengetahui peran PGPR terhadap dampak negatif genangan air pada tanaman cabai rawit sebagai salah satu solusi untuk mengurangi kerugian petani. Penelitian menggunakan rancangan acak lengkap pada cabai rawit yang diberikan perlakuan berupa kontrol tanpa PGPR (K(-)), kontrol dengan PGPR (K(+)), perlakuan genangan air selama 2 hari dengan pemberian PGPR 7 hari setelahnya (P(+)) dan tanpa pemberian PGPR (P(-)). Hasil uji two way Anova menunjukkan bahwa genangan air berpengaruh signifikan terhadap respon pertambahan tinggi tanaman, sudut kelengkungan tangkai daun dan kelayuan sedangkan pemberian PGPR berpengaruh signifikan terhadap pertambahan tinggi tanaman dan jumlah cabang.

Pengaruh Problem Based Learning Berbantuan Media Colors By Numbers Terhadap Kemampuan Berhitung Siswa Sekolah Dasar
Full text linkMathematics subjects with the development of numeracy skills are two inseparable things because numeracy skills encourage students to develop critical, logical and creative thinking. The ability to count also has great relevance in students' lives because it is directly related to everyday situations. However, there is a problem faced by students at SDN Kramat 06, namely their lack of numeracy skills. Through field observations, there are findings that show that numeracy skills at SDN Kramat 06 are still relatively low. This is shown in the learning outcomes and oral test scores carried out in class which are still relatively low. This situation is because the use of conventional learning models makes students passive and the teacher is too dominant so that students can only listen to the explanation given. The selection of the Problem Based Learning Model assisted by Colors by Numbers media is expected to improve students' numeracy skills. The results of statistical analysis show that the Problem Based Learning model assisted by Colors by Numbers media makes changes to improving the numeracy skills of class IV students at SDN Kramat 06. This is reflected in the results of the experimental class achieving better numeracy skills than the control class and the use of the Problem Based Learning model with the help of Colors by Numbers media has a significant effect on the numeracy skills of class IV students at SDN Kramat 06
