Abstract

Penelitian survey mengenai kajian sifat kimia, sifat fisik tanah dan hubungannya dengan produktivitas tanaman pala di Kabupaten Minahasa, Provinsi Sulawesi Utara yaitu di Kecamatan Mandolang yang terletak pada ketinggian 109-555 m dpl. Analisis tanah di Laboratorium Kimia dan Kesuburan Tanah Balai pengkajian Teknologi Pertanian Sulawesi Selatan. Sampel tanah diambil dari masing-masing lokasi secara kompositĀ  untuk di analisis di laboratorium. Analisis tanah meliputi tekstur, pH, C-Organik, N-Total, P-Tersedia, K-Total, Ca, Mg, Na KTK, dan Kejenuhan Basa. Hasil penelitian menunjukkan areal pertanaman pala bertekstur lempungĀ  dengan pH agak masam hingga netral, kandungan C-Organik rendah dan kadar N,P dan K rendah, KTK tinggi dan nilai kejenuhan basa sedang, kadar Ca dan Mg tinggi sedangkan kadar Na rendah, sehingga karakteristik tanah di areal pertanaman pala memenuhi syarat untuk budidaya pala dengan catatan perlu penambahan pupuk N,P dan K.

Every child develops in various unique ways, but there are several general developments that can be identified in elementary school children, namely children aged 6 to 12 years. As for physical development, at this age children experience rapid body growth, fine and gross motor skills continue to develop. As for the cognitive development of children during this period, they acquire higher cognitive abilities. In social development, children at this time understand and are involved in more complex social interactions. During this period of emotional development, children learn to manage emotions better, identify and express feelings more accurately. The aim of this research was to find out specifically the development of children during elementary school. In this research, the author uses a type of research in the form of library research. From this research, the researcher concluded that aspects of a child's development can be influenced by the surrounding environment. Therefore, teachers and parents should have knowledge in efforts to maximize aspects of a child's development because, if every aspect can develop well, then the child is able to carry out tasks. the task of development is also good.

Abstract

Difficulties in speaking include students being able to convey messages well but still using their mother tongue, being embarrassed and nervous about speaking in front of the class and even forgetting what they are going to convey. Role-playing is an effective learning model in improving students' speaking skills. This model can help students become more active, independent and happy during the learning stage. This research aims to determine the effect of the role-playing learning model on students' speaking skills. By applying a quantitative approach and quasi-experimental design, this research involved a population of 112 students. The research sample consisted of 59 students, where class IV A as the experimental class included 31 students and class IV B as the control class consisted of 28 students. The instrument used in this research is a non-test technique in the form of a performance test. Hypothesis testing is carried out using the t test after first carrying out a normality test. The results of the significance value (2-tailed) of 0.001 < 0.05 indicate that the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted.
