ABSTRACT

This study aims to determine the effect of the growth of oil palm seedlings on the concentration of liquid fertilizer from palm oil processing factory waste and to determine the best growth effect on the concentration of liquid organic fertilizer from palm oil processing factory waste. This research was conducted from May to October 2022 at the Greenhouse, UPTD Martapura Slaughterhouse, Banjar Regency. This study was structured using a one-factor complete check design (CRD) with 5 treatments and 4 repetitions, so that 20 experimental units were obtained. The distance between polybags is 30 cm x 40 cm. Each experimental unit consisted of 4 polybags of oil palm seeds, making a total of 80 polybags of oil palm seeds. The dose used was 100 ml for each plant, with concentrations given starting from the control or without POC administration, 40 ml 1-1, 60 ml-1 and 80 ml 1-1. The results showed that there was no significant effect of giving POC from palm oil processing factory waste on seedling height, number of leaves, leaf width, leaf length, and stem diameter. However, there is a significant effect on the wet weight of the oil palm seedlings. The treatment of POC administration of palm oil processing factory waste with concentrations of 20 ml 1-1, 40 ml 1-1, 60 ml-1 and 80 ml 1-1 showed better results than the control in observing seedling height, leaf width, leaf length, stem diameter and wet weight.

Penelitian ini bertujuan untuk mengetahui pengaruh pertumbuhan bibit kelapa sawit terhadap pemberian konsentrasi pupuk cair limbah pabrik pengolahan kelapa sawit dan mengetahui pengaruh pertumbuhan terbaik terhadap pemberian konsentrasi pupuk organic cair limbah pabrik pengolahan kelapa sawit. Penelitian ini dilaksanakan pada Mei sampai Oktober 2022 bertempat di Rumah Kaca, UPTD Rumah Potong Hewan Martapura, Kabupaten Banjar. Penelitian ini disusun menggunakan rancangan ack lengkap (RAL) satu factor dengan 5 perlakuan dan 4 pengulangan, sehingga didapat 20 satuan perrcobaan. Jarak antar polybag adalah 30 cm x 40 cm. Tiap satuan percobaan terdiri dari 4 polybag bibit kelapa sawit sehingga berjumlah 80 polybag bibit kelapa sawit. Adapun dosis yang digunakan adalah 100 ml pada tiap tanaman, dengan konsentrasi yang diberikan mulai dari kontrol atau tanpa pemberian POC, 40 ml 1^-1, 60 ml^-1 dan 80 ml 1^-1. Hasil penelitian menunjukan bahwa Tidak adanya pengaruh nyata pemberian POC limbah pabrik pengolahan kelapa sawit terhadap tinggi bibit, jumlah daun, lebar daun, Panjang daun, dan diameter batang.  Tetapi terdapat pengaruh nyata pada berat basah bibit kelapa sawit. Perlakuan pemberian POC limbah pabrik pengolahan kelapa sawit dengan konsentrasi 20 ml 1^-1, 40 ml 1^-1, 60 ml^-1 dan 80 ml 1^-1 menunjukan hasil lebih baik daripada kontrol pada pengamatan tinggi bibit, lebar daun, panjamg daun diameter batang dan berat basah.

Kata kunci: pupuk organik cair; Prenursery; kelapa sawit.
