PENGARUH PEMBERIAN EKSTRAK TAUGE TERHADAP PERTUMBUHAN BIBIT BALANGERAN (Shorea balangeran) DI PERSEMAIAN BALAI PENERAPAN STANDAR INSTRUMEN LINGKUNGAN HIDUP DAN KEHUTANAN (BPSILHK) BANJARBARU

Abstract

ABSTRACT. The presence of balangeran (Shorea balangeran) in its natural habitat has started to decrease, due to the high demand for balangeran. One way to preserve balangeran is through exsitu cultivation. The growth of balangeran can be optimized through the application of growth regulators (ZPT) using the appropriate concentration. This study aims to determine the percentage of survival, concentration and effect of bean sprout extract on the growth of balangeran seedlings. Randomized Completely Design method was used in this study. The treatments used were 4 and each treatment was repeated 20 times so that the number of seedlings used was 80. Analysis of field results using Smirnov Kolmogrov normality test and homogeneity test according to Barlett's variance. Based on the results of the study, it was found that the percentage of living seedlings of Balangeran (Shorea balangeran) during the study was 100% in each treatment, the application of bean sprout extract with a concentration of 150 g/l water produced the best response in height increase (4.7cm), number of leaves increase (14 strands) and diameter increase (1.9 mm) and the application of ZPT produced no significant effect on the height increase of Balangeran seedlings, but a significant effect on diameter and a very significant effect on the number of leaves

ABSTRAK. Keberadaan balangeran (Shorea balangeran) di habitat aslinya sudah mulai berkurang, hal tersebut karena banyaknya permintaan akan balangeran. Salah satu cara untuk menjaga kelestarian balangeran melalui pembudidaya secara exsitu. Pertumbuhan balangeran dapat dioptimalkan melalui pengaplikasian zat pengatur tumbuh (ZPT) menggunakan konsentrasi yang sesuai. Penelitian tersebut bertujuan supaya menemukan persentase hidup, konsetrasi serta dampak pemberian ekstak tauge pada pertumbuhan bibit balangeran. Metode Rancangan Acak Lengkap (Randomized Completely Design) digunakan dalam penelitian ini. Perlakuan yang digunakan sebanyak 4 dan masing-masing perlakuan dilakukan pengulangan 20 sehingga jumlah bibit yang dipakai 80. Analisis hasil lapangan memakai uji normalitas Smirnov Kolmogrov serta uji homogenitas sesuai ragam Barlett. Berdasarkan hasil penelitian ditemukan bahwa persentase hidup bibit balangeran (Shorea balangeran) selama penelitian 100% setiap perlakuan, Pemberian Ekstrak Tauge dengan konsentrasi 150 gr/l air menghasilkan respon terunggul untuk pertambahan tinggi (4,7cm), pertambahan total daun (14 helai) serta pertambahan diameter (1,9 mm) serta pemberian ZPT menghasilkan pengaruh tidak nyata pada pertambahan tinggi bibit balangeran, tetapi berdampak nyata pada diameter serta berpengaruh paling nyata terhadap total daun.
