Pengelolaan Produksi Tanaman Hias Hamparan Vinca (Catharanthus roseus) dan Celosia (Celosia argentea) di PT. Bina Usaha Flora, Cianjur, Jawa Barat

Abstract

Kegiatan magang dilaksanakan pada bulan Januari – Mei 2021 di PT. Bina Usaha Flora, Cianjur, Jawa Barat. Kegiatan magang bertujuan meningkatkan pengetahuan dan keterampilan mengenai teknik pengelolaan produksi usaha tanaman hias, terutama tanaman hias hamparan, termasuk jadwal produksi mulai dari persiapan tanam hingga siap panen, dan kriteria panen tanaman Celosia argentea dan Catharanthus roseus. Kegiatan tambahan dalam magang yaitu mempelajari pengaruh aplikasi retardan paclobutrazol pada Celosia argentea untuk menghasilkan tanaman yang pendek dan seragam. Ketinggian Celosia argentea bisa mencapai 100 cm yang membuat tanaman mudah rebah dan kesulitan dalam transportasi. Pengukuran pertumbuhan pada vinca meliputi tinggi tanaman, jumlah cabang sekunder, jumlah bunga, dan diameter bunga. Pengukuran pertumbuhan Celosia argentea meliputi tinggi tanaman, jumlah daun, jumlah cabang sekunder, jumlah ruas, jumlah bunga, dan ukuran bunga. Kegiatan budidaya tanaman hias yang dilakukan meliputi persiapan media semai, persemaian, persiapan media tanam, pindah tanam, penyiraman, pemumpukan, pengendalian hama penyakit, dan panen. Hasil pengamatan kriteria panen tanaman Vinca menunjukkan hasil yang sesuai dengan kriteria perusahaan. Aplikasi retardan paclobutrazol pada konsentrasi 10 ppm dengan cara disiram pada media efektif dapat mengurangi tinggi tanaman Celosia dan memenuhi kriteria yang diinginkan perusahaan.

The internship activities was carried out in January – May 2021 at PT. Bina Usaha Flora, Cianjur, West Java. This aims of the internship is to increase knowledge and skills about production management and cultural techniques in ornamental plants, particularly of bedding plants, including production schedule from planting preparation until ready to harvest, the harvest criteria of Celosia argentea and Catharanthus roseus. An additional activity was conducted during the internship, i.e. to study the effects of retardant paclobutrazol application in Celosia argentea in order to produce short and compact plants. Celosia argentea height could reach 100 cm which make them prone to lodging and more difficult to transport. Growth measurement on Vinca included plant height, number of branches, number of flowers, and diameter of flowers to determine harvest criteria. Growth measurement on Celosia argentea included plant height, number of leaves, number of branches, number of internodes, number of flowers, and diameter of flowers. Cultivation activities include preparation of nursery media, nurseries, preparation of planting media, transplanting, watering, fertilizing, controlling pests and diseases, and harvest. The harvest criteria of Vinca has been conducted in accordance with the company’s criteria.
