Abstract

Taman Nasional Gunung Gede Pangrango (TNGGP) Jawa Barat merupakan salah satu taman nasional yang mengkonservasi jenis anggrek. Penelitian ini bertujuan untuk mengetahui spesies anggrek apa saja yang terdapat di Resort PTN Wilayah II Selabintana TNGGP, mengetahui tingkat keanekaragaman jenis anggrek, dan mengetahui pohon inang yang digunakan sebagai habitat anggrek epifit. Penelitian dilakukan di Resort PTN Selabintana TNGGP pada lokasi I, II, dan III. Metode pengambilan data dilakukan dengan Visual Encounter Survey (VES) di sepanjang jalur dengan radius ke kanan dan ke kiri 1 meter. Hasil penelitian ditemukan 7 jenis anggrek yakni Liparis pallida, Coelogyne sp., Appendicula angustifolia, Bulbophyllum angustifolium, Eria multiflora, Oberonia sp., dan Ceratostylis sp.. Spesies yang paling dominan ditemukan adalah Liparis pallida, Ceratostylis sp., dan Coelogyne sp. Tingkat keanekaragaman jenis anggrek di Resort PTN Selabintana tergolong sedang. Pohon inang yang digunakan sebagai habitat anggrek epifit adalah Schima wallichii, Ficus sp., Cyathea sp., batang pohon yang sudah mati dan ranting jatuh.

Abstract

Pakcoy (Brassica rapa) is one type of vegetables that belongs to the mustard group and is widely consumed by the community. Pakcoy production in 2023 was 686,876 tons. Efforts to increase the amount of pakcoy production can be done with proper fertilization techniques using fertilizers. The use of organic fertilizers is the right solution in overcoming these problems. Organic waste around the community, such as banana kepok peels and fronds can be used as organic fertilizer. The purpose of this research is to obtain information about the effectiveness of Liquid Organic Fertilizer (LOF) of banana kepok peel and fronds on pakcoy growth. This study used an experimental method with a Randomized Group Design (RGD) consisting of 5 LOF treatments and each treatment consisted of 4 replicates, so that the total number of 20 experimental units. The LOF concentrations given are A1 (0%), A2 (10%), A3 (25%), A4 (50%) and A5 (75%). The growth parameters observed were plant height, number of leaves, leaf width and wet weight. The results of data analysis using the ANOVA test showed a significant effect on all treatments. This was followed by a Duncan test to determine which treatments had significantly different averages. It was concluded that the use of LOF with treatment concentration A2 (10%), effectively increased the growth and yield of pakcoy. Thus, it is suitable to be recommended as an alternative fertilizer for pakcoy cultivation.
