Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian Atonik dalam berbagai konsentrasi terhadap pertumbuhan mata tunas okulasi bibit karet pada stadium stum mata tidur. Bibit stum mata tidur merupakan bibit yang mata tunasnya belum tumbuh. Kelebihannya adalah ringan, mudah diangkut, dan biayanya murah. Namun persentase kematian bibit cukup besar dibandingkan dengan stadium lain. Karena itu perlu untuk diberi beberapa perlakuan untuk meningkatkan pertumbuhan mata tunas pada stum mata tidur tersebut. Salah satu hal yang dapat digunakan untuk membantu pertumbuhan mata tunas adalah dengan pemberian hormon atau zat pengatur tumbuh. Konsentrasi yang digunakan adalah Atonik 0,5 ml/liter air, Atonik 1 ml/liter air , Atonik 1,5 ml/liter air , dan tanpa penggunaan Atonik. Sedangkan perlakuan dasar diberikan sama terhadap semua bibit karet. Hasil penelitian menunjukkan bahwa konsentrasi Atonik 1,5 ml/liter air memberikan pengaruh paling baik dan berbeda nyata terhadap pertumbuhan mata tunas okulasi bibit karet pada semua parameter pengamatan, yaitu panjang tunas, jumlah daun dan diameter tunas, dibandingkan dengan perlakuan konsentrasi Atonik lainnya

There are several stages of work in oil palm plantations that require special attention, one of which is oil palm harvesting work because this work requires skills other than physical strength. Harvesters are required to be skilled in harvesting and have knowledge of correct harvesting techniques both in terms of harvest quality and quantity because this work is directly related to fresh fruit bunches (FFB). The research aims to determine the characteristics and level of knowledge of harvesters regarding palm oil harvesting techniques. The data used is questionnaire data as primary data. Before being distributed to respondents, the questionnaire was tested for validity, then continued with a reliability test. The data was analyzed using mathematical calculations. Employees at PT. Alam Jaya Persada is male with 100%. The age of 100% harvest employees falls within the productive age group, namely 18-53 years. The majority of education, 69.4%, only received elementary school education.
