Abstract
Agroforestri banyak dikembangkan di Indonesia karena manfaat ekonomi bagi masyarakat, manfaat sosial, ekologi dan konservasi budaya. Program Unit Percontohan Usaha Pelestarian Sumber Daya Alam (UP - UPSA) dikembangkan sebagai media penyuluhan guna meningkatkan pemahaman dan partisipasi warga dalam pelestarian sumber daya alam dan konservasi tanah dan air. Penelitian ini bertujuan untuk mengevaluasi laju dekomposisi berbagai jenis seresah di berbagai macam penggunaan lahan yang berbeda. Penelitian ini dilaksanakan pada akhir Februari hingga akhir Mei 2024 di lahan UP - UPSA Desa Tawang Argo, Kecamatan Karangploso, Kabupaten Malang. Perlakuan yang diuji disusun menurut Rancangan Acak Kelompok (RAK), dengan 2 faktor yang diuji. Faktor 1, Jenis seresah: (1) Mix seresah Pinus + Kopi (BMP) (2) Mix seresah Pinus + Alpukat + Lemon + Sayur (PALS), (3) Mix Pinus + Pisang (PPS), dan (4) seresah Kubis saja (TMS). Faktor 2, Sistem penggunaan lahan: (1) Plot Mix BMP, (2) Plot Mix PALS, (3) Plot Mix PPS, (4) Plot monokultur TMS. Pengamatan laju dekomposisi dilakukan menurut metode TSBF (Tropical Soil Biology and Fertility), yaitu berdasarkan penurunan berat masa seresah yang diuji per waktu pengamatan (minggu ke 2, 4, 6, 8, 10, dan 12). Contoh seresah dimasukan ke litter bag ukuran 30 x 25 x 2 cm3. Variabel yang diamati adalah penurunan massa seresah tiap waktu pengamatan, iklim mikro (suhu tanah, suhu udara, kelembaban tanah, kanopi), serta kualitas seresah (C- organik, N total, C/N rasio, lignin, polifenol) yang dilakukan pada saat awal percobaan saja.
English Abstract
Agroforestry is widely developed in Indonesia because of its economic benefits for the community, social benefits, ecology and cultural conservation. The Natural Resource Conservation Business Pilot Unit (UP - UPSA) program was developed as a medium for extension to increase public understanding and participation in natural resource conservation and soil and water conservation. The purpose of this study was to evaluate the decomposition rate of various types of litter in various different land uses. This study was conducted from February to May 2024 in UP – UPSA plot (in UB Forest area), in Tawang Argo Village, Karangploso District, Malang Regency. The treatments tested were arranged according to a Randomized Block Design (RAK), with 2 factors tested. Factor 1, Type of litter: (1) Mix Pine + coffe (BMP), (2) Mix of Pine litter + avocado + lemon + vegetables (PALS) , (3) Mix Pine + banana (PPS), and (4) Cabbage litter only (TMS). Factor 2, Land use system: (1) BMP Mix Plot, (2) PALS Mix Plot, (3) PPS Mix Plot, (4) TMS monoculture plot. Observation of decomposition rate was conducted according to the TSBF (Tropical Soil Biology and Fertility) method, based on the weight loss of the tested litter mass per observation time (weeks 2, 4, 6, 8, 10, and 12). Litter samples were inserted into 30 x 25 x 2 cm3 litter bags. The variables observed were the decrease in litter mass per observation time, microclimate (soil temperature, air temperature, soil moisture, canopy), while litter quality (C-organic, total N, C/N ratio, lignin, polyphenols) were analyzed prior the experiment.
