Abstract

Soil is a natural medium that is one aspect of supporting the life of all living things, including plants. Soil chemical properties greatly affect the growth process of oil palm plants, especially in the production process of oil palm fruit bunches. The purpose of this study was to determine the soil's chemical properties in oil palm plantations. The method used in this study is a descriptive method by conducting surveys and laboratory analysis. Soil samples were taken randomly at a depth of 0-20cm at four points of plantation land. Several parameters have been analyzed, such as pH, total N, CEC and exchangeable Al (Al-dd). Soil samples were analyzed at the Laboratory of Soil Research Indonesian Oil Palm Research Institute (PPKS) Medan. Determination of the criteria for assessing soil chemical properties based on the soil fertility standards issued by the Soil Research Center (BPT) Bogor (2009). The results of the analysis showed that the soil pH was slightly acidic, total N was low, CEC was low and Al-dd was very low.

Abstract

Penelitian ini bertujuan untuk menguji pengaruh metode drill terhadap keterampilan passing bawah dalam permainan bola voli pada siswa kelas 6 SDN Cinurman. Menggunakan pendekatan kuantitatif dengan metode quasi-eksperimen. Sampel penelitian melibatkan 30 siswa kelas 6 SDN Cinurman yang dipilih melalui teknik purposive sampling, kemudian dibagi menjadi kelompok kontrol dan kelompok eksperimen. Pengumpulan data dilakukan melalui pre-test dan post-test keterampilan passing bawah. Data yang terkumpul dianalisis menggunakan Microsoft Excel dan SPSS Versi 26. Hasil penelitian menunjukkan bahwa kelompok kontrol, yang berlatih tanpa metode drill, mengalami peningkatan rata-rata keterampilan passing bawah dari 19,20 (pre-test) menjadi 26,20 (post-test), atau sekitar 3,64% dari hasil pre-test. Sementara itu, kelompok eksperimen yang menggunakan metode drill menunjukkan peningkatan rata-rata yang lebih signifikan, dari 20,66 (pre-test) menjadi 31,33 (post-test), dengan peningkatan sebesar 5,16% dari hasil pre-test. Hasil analisis data diperoleh nilai t-hitung 25,298 dan t-tabel 1,701, dengan nilai signifikansi 0,000. Karena t-hitung 25,298 > 1,701 dan nilai signifikansi 0,000 <  0,05, dapat disimpulkan bahwa terdapat perbedaan yang signifikan. Ini berarti hipotesis alternatif (Ha) diterima dan hipotesis nol (Ho) ditolak. Dengan demikian, penelitian ini menyimpulkan bahwa metode drill memberikan peningkatan persentase keterampilan passing bawah yang lebih besar dibandingkan latihan tanpa metode drill

Abstract

Background: Parental parenting styles play a crucial role in children's personality development, influencing various aspects such as self-esteem, independence, and social skills. Objective: The purpose of this study is to analyze the influence of parental parenting styles on children's personality development in high school students, focusing on how authoritative, authoritarian, permissive, and neglectful parenting styles affect children's character. Method: This study uses a quantitative approach with a correlational design. Data were collected through questionnaires given to parents and students, as well as interviews to obtain more in-depth information about the parenting styles applied. Data analysis was performed using regression tests to determine the influence of parenting styles on children's personality development. Result: Parental parenting styles have a significant influence on children's personality development. Authoritative parenting is associated with better self-esteem, independence, and social skills, while authoritarian and permissive parenting tends to hinder children's positive development. Conclusion: Good parenting, remarkably authoritative parenting, has a significant influence on the development of a healthy child's personality. Therefore, parents are expected to employ supportive parenting styles, enabling children to develop into independent, confident individuals with strong social skills. Contribution: This study makes a significant contribution to the literature in the field of developmental psychology and family counseling.
