Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemanfaatan limbah cangkang telur ayam (Es) sebagai pupuk organik cair (POC) terhadap karakteristik morfologi Mucuna bracteata (Mb). Penelitian ini dilaksanakan pada bulan Mei sampai dengan Juni 2021 di laboratorium terpadu Politeknik LPP Yogyakarta. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) Non Faktorial yaitu dosis POC yang berbeda yang terdiri dari P0 (kontrol), P1 (25 ml POC), P2 (50 ml POC), P3 (75 ml POC) dan P4 (100 ml POC). Karakteristik morfologi yang diamati yaitu tinggi tanaman, jumlah daun dan bobot basah tanaman. Analisis data dilakukan menggunakan Anova dengan tingkat kepercayaan 5%, apabila terdapat perbedaan nyata pada perlakuan dilakukan uji lanjut menggunakan Ducan Multiple Range Test (DMRT). Hasil penelitian menunjukan terdapat pengaruh nyata terhadap pemberian POC pada perlakuan P3 (75 ml POC) pada seluruh variabel karakteristik morfologi yang diamati, yaitu tinggi tanaman (12,17 cm), jumlah daun (7,46 helai) dan bobot basah tanaman (7,67 gram). POC diduga mampu menambah makrohara sekunder pada media tanam Mb terutama Ca dan Mg. Makrohara sekunder Ca berperan penting dalam diferensiasi sel sehingga akan berpengaruh terhadap tinggi tanaman dan jumlah daun pada Mb, sedangkan mikro hara Mg berperan sebagai prekusor pembentukan klorofil pada daun Mb.Kata kunci: cangkang telur, makrohara sekunder, morfologi, Mucuna bracteata,

Abstract

The transformation of the oil palm industry toward more efficient production systems has accelerated the implementation of mechanization in plantation operations. The success of mechanization adoption is determined not only by the availability of technology but also by the readiness of human resources to accept and utilize such technology. This study aims to analyze the level of technology readiness for intensive mechanization implementation in on-farm operations within PT Perkebunan Nusantara IV (PalmCo). A quantitative descriptive approach was employed using the Technology Readiness Index (TRI), which consists of four dimensions: optimism, innovativeness, discomfort, and insecurity. Data were collected through questionnaires distributed to respondents from six PalmCo estates representing Regions I, II, and III. The study covered mechanization in land preparation and planting, fertilization, maintenance and weed control, harvesting, and transportation activities. Data were analyzed by calculating the technology readiness index and classifying the results into low, medium, and high technology readiness categories. The results showed that mechanization in land preparation and fertilization achieved TRI values of 3.437 and 2.966, respectively, indicating Medium Technology Readiness. In contrast, weed control and harvesting-transportation activities recorded TRI values of 2.866 and 2.804, respectively, indicating Low Technology Readiness. Optimism was identified as the most influential dimension contributing to technology readiness across all mechanization activities. The lower readiness levels were mainly associated with plantation topography, limited supporting infrastructure, and the absence of fully integrated mechanization implementation. These findings provide valuable insights for PalmCo in developing more effective mechanization strategies tailored to the operational characteristics of oil palm plantations.
