Pengendalian Gulma Kelapa Sawit (Elaeis guineensis Jacq) di Kebun Seed Garden Buatan, PT Inti Indosawit Subur, Riau.

Abstract

Gulma di lahan kelapa sawit yang tidak dikendalikan menurunkan hasil panen sehingga perlu pengendalian gulma yang efektif dan efisien. Magang memiliki tujuan umum meningkatkan kemampuan teknis dan manajerial dalam kegiatan budidaya kelapa sawit serta tujuan khusus menambah pemahaman dalam pengendalian gulma di Kebun Seed Garden Buatan, PT Inti Indosawit Subur, Riau. Magang dilaksanakan di KSB, PT Inti Indosawit Subur, Pangkalan Kerinci, Pelalawan, Riau pada bulan Januari sampai Mei 2023. Metode yang digunakan metode langsung (data primer) dan tidak langsung (data sekunder). Pengamatan data primer gulma dengan NJD menunjukkan gulma yang dominan di areal piringan yaitu Eleusine indica menunjukkan SDR tertinggi yaitu 45,28% pada TBM, 30,92% pada TM muda, dan 27,14% pada TM tua. Centotheca lappacea nilai SDR tertinggi pada TM muda 35,42% dan TM dewasa 55,7%. Cyperus kyllingia nilai SDR tertinggi gulma ini pada TBM yaitu 46%, TM muda yaitu 50,05%, dan TM dewasa 27,29%. Asystasia gangetica nilai SDR tertinggi di TM dewasa senilai 17,03%. Pengendalian gulma di KSB dilaksanakan dengan cara manual, kultur teknis, kimiawi, dan mekanis. Penting dilakukan pengawasan mengenai kondisi alat semprot agar penggunaan biaya pengendalian lebih efisien. Persentase tingkat penggunaan APD sebesar 58% dan tergolong rendah.

Uncontrolled weeds in oil palm fields reduce yields so effective and efficient weed control is needed. The internship has a general objective to improve technical and managerial skills in oil palm cultivation activities and a specific objective to increase understanding in weed control in the Artificial Seed Garden, PT Inti Indosawit Subur, Riau. The internship was carried out at KSB, PT Inti Indosawit Subur, Pangkalan Kerinci, Pelalawan, Riau from January to May 2023. The methods used were direct (primary data) and indirect (secondary data). Observation of primary weed data with NJD showed that the dominant weed in the disk area, namely Eleusine indica, showed the highest SDR of 45,28% in TBM, 30,92% in young TM, and 27,14% in old TM. Centotheca lappacea had the highest SDR value in young TM at 35,42% and mature TM at 55,7%. Cyperus kyllingia had the highest SDR value in TBM at 46%, young TM at 50,05%, and mature TM at 27,29%. Asystasia gangetica had the highest SDR value in mature TM at 17,03%. Weed control in KSB is carried out by manual, technical culture, chemical, and mechanical means. It is important to monitor the condition of the spray equipment so that the use of control costs is more efficient. The percentage of PPE usage rate is 58% and is classified as low.
