Abstract

Tanaman padi (Oryza sativa L.) merupakan tanaman pangan penting yang telah menjadi makanan pokok lebih dari setengah penduduk dunia. Penurunan produksi padi dapat disebabkan oleh sistem tanam tanaman padi yang digunakan petani. Sistem tanam dalam budidaya padi akan mempengaruhi hasil produksi padi. Produksi padi dapat ditingkatkan melalui penggunaan sistem tanam yang tepat. Penurunan produksi padi ini tergantung adanya faktor-faktor produksi yang digunakan yaitu seperti sistem tanam, dan serangan organisme pengganggu tanaman. Keberadaan OPT juga dapat dipengaruhi oleh sistem tanam yang digunakan. Salah satu OPT yang keberadaannya dipengaruhi oleh sistem tanam yaitu gulma. Tujuan penelitian ini untuk mengetahui pengaruh pengendalian gulma dan sistem tanam padi terhadap hasil dan pertumbuhan tanaman padi. Berdasarkan hasil penelitian disimpulkan bahwa Perlakuan penegndalian gulma tidak memberikan pengaruh terhadap pertumbuhan pengamatan tinggi tanaman, jumlah anakan dan jumlah malai. Tetapi berpengaruh terhadap hasil bobot gabah per tanaman, bobot gabah per plot dan berat 1000 butir. Pada perlakuan P1 (pengendalian secara manual) merupakan perlakuan terbaik. Perlakuan sistem tanam menunjukkan tidak berpengaruh terhadap pertumbuhan pengamatan tinggi tanaman, jumlah anakan dan jumlah malai. Tetapi berpengaruh terhadap hasil bobot gabah per tanaman dan bobot gabah per plot. Pada perlakuan J2 ( jajar legowo 6:1) merupakan sistem tanam terbaik. Perlakuan interaksi antara pengendalian dan sistem tanam menunjukkan tidak berpengaruh terhadap pertumbuhan dan hasil.

Abstract

Terung merupakan komoditas hortikultura penting di Indonesia, namun produktivitasnya sering terkendala oleh penurunan kesuburan tanah akibat penggunaan pupuk anorganik secara berlebihan. Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian pupuk organik cair (POC) daun kelor dan komposisi media tanam berbasis pupuk kandang kambing terhadap pertumbuhan dan hasil tanaman terung. Penelitian dilaksanakan menggunakan Rancangan Acak Kelompok (RAK) dua faktor, yaitu konsentrasi POC daun kelor (0, 75, 150, dan 225 ml/L) dan komposisi media tanam (tanpa pupuk kandang, perbandingan 1:1, dan 1:2 antara pupuk kandang kambing dan tanah), dengan tiga ulangan. Hasil menunjukkan bahwa perlakuan POC daun kelor dan media tanam berpengaruh nyata terhadap beberapa parameter pertumbuhan dan hasil, terutama tinggi tanaman, jumlah daun, jumlah buah per tanaman, dan berat buah. Kombinasi perlakuan terbaik ditemukan pada konsentrasi POC 150 ml/L dengan media tanam 1:1, yang memberikan peningkatan signifikan pada jumlah daun dan panjang buah. Temuan ini menunjukkan bahwa integrasi POC daun kelor dan pupuk kandang kambing dapat menjadi alternatif ramah lingkungan untuk meningkatkan produktivitas terung.

Abstract

Abstract This study aims to analyze the effect of silicon (Si) application on soil microbial populations, particularly bacteria, nitrogen (N) and phosphorus (P) uptake under various growing media conditions, and its implications for corn (Zea mays L.) growth. The experiment used a completely randomized factorial design with two factors: Si concentration (0, 5, 10, and 15% SiO₂) and type of soil condition (standard soil, high-N soil, P-deficient soil, and high-organic-matter soil). The results showed that Si fertilizer application increased bacterial populations by 18.87% in the control medium, 134.6% in high-N soil, 134.7% in P-deficient soil, and 20% in high-organic matter soil, while the application of 15% Si in P-deficient soil increased P uptake by 53.7% compared to without Si, and in high-N soil, the application of 15% Si reduced tissue N content but increased its utilization efficiency. The increase in P uptake occurred through ionic competition between SiO₄⁴⁻ and PO₄³⁻ at the uptake site, while the decrease in tissue N content indicated Si's role in optimizing N utilization. Leaf Si content was relatively higher in all treated media compared to the control, followed by a tendency toward increased plant dry weight and stomatal number. These results indicate that Si application under nutrient stress conditions can balance N and P availability and improve physiological parameters supporting growth.

Abstract

Lack of proficiency in badminton backhand shots was the driving force behind this study. Through analysis during the initial observation, the researcher found that there were still training patterns that had yet to be considered so that they were more reproduced in games. There was no variety of exercises applied. Therefore, researchers researched to determine the effect of the drill training method on badminton backhand shot skills. This type of research is quantitative research using the "pre-experimental design" research method, namely One-Group et al. The population in this study were all PB—Sarma Pangkalpinang athletes, totaling 20 people. The sample in this study was all members of the population. The data analysis technique in this study uses normality tests and hypothesis testing. The count value of 18.728 is higher than the t table value of 1.729, which means that Ho is not true and Ha is true. This means that the study titled "The Effect of the Drill Training Method on Badminton Backhand Hit Skills at Club PB. Sarma Pangkalpinang" has a significant effect.
