Peningkatan Produktivitas Sadapan Getah Pinus Melalui Penggunaan Stimulansia Organik Berbahan Aktif Nanas Muda (Ananas comosus)

Abstract

Stimulansia anorganik mampu meningkatkan produktivitas getah pinus, tetapi berdampak negatif dibandingkan stimulansia organik ramah lingkungan. Penelitian ini bertujuan mengukur produktivitas getah pinus dari penggunaan stimulansia organik nanas muda, menganalisis pengaruh konsentrasi dan besarnya nilai tambah perlakuan stimulansia nanas muda. Penelitian dilakukan di RPH Leuwiliang menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan, yaitu kontrol, stimulansia nanas muda konsentrasi 10%, 20%, 30% dan SR-25. Analisis data menggunakan Welch’s ANOVA dan uji lanjut Games Howell. Hasil penelitian menunjukkan bahwa pemberian stimulansia berpengaruh nyata terhadap produktivitas getah pinus. Produktivitas tertinggi diperoleh pada stimulansia nanas muda konsentrasi 20% sebesar 6,543 g/quarre/hari atau meningkat 84,75% dibandingkan kontrol, meskipun lebih rendah dari perlakuan SR-25 sebesar 10,400 g/quarre/hari atau meningkat 193,65%. Nanas muda berpotensi sebagai stimulansia organik alternatif karena mampu meningkatkan produktivitas getah dengan biaya relatif murah, ramah lingkungan dan lebih aman terhadap kesehatan pohon dibandingkan stimulansia anorganik.

Inorganic stimulants are able to increase pine resin productivity, but have a negative impact compared to environmentally friendly organic stimulants. This study aims to measure pine resin productivity from the use of unripened pineapple organic stimulant, analyze the effect of concentration and added value of the unripened pineapple stimulant treatment. The research was conducted at RPH Leuwiliang using a Completely Randomized Design (CRD) with five treatments, namely control, unripened pineapple stimulant at concentrations of 10%, 20%, 30%, and SR-25. Data analysis used Welch's ANOVA and the Games-Howell post hoc test. The results showed that the application of stimulants had a significant effect on pine resin productivity. The highest productivity was obtained with the unripened pineapple stimulant at a concentration of 20% of 6.543 g/quarre/day or an increase of 84.75% compared to the control, although lower than the SR-25 treatment of 10.400 g/quarre/day or an increase of 193.65%. Unripened pineapple has potential as an alternative organic stimulant because it is able to increase resin productivity at a relatively low cost, is environmentally friendly, and is safer for tree health compared to inorganic stimulants.
