Abstract

The aim of this experiment is to evaluate the impact of chitosan-NPK slow-release fertilizer (CS-NPK SRF) on the germination and growth of silk tree and rice in different planting patterns, as well as to assess the nutrient release rate of the SRF. The germination test followed a complete randomized design, incorporating a single factor (fertilizer type), namely no fertilizer (F0), SRF CS 0.5% weight 0.03 g (F1), SRF CS 0.5% 0.01 g (F2), SRF CS 0.7% 0.03 g (F3), SRF CS 0.7% 0.01 g (F4), and conventional NPK fertilizer (F5). The growth test utilized a 2-factor split-plot design, with the primary factor being the planting pattern (sengon/rice monoculture-SM/RM and sengon-rice agroforestry-AF) and the second factor being the fertilizer type. Results indicate that F2 and F4 yielded the highest germination and growth values in both plants, although not significantly different from F0. These findings suggest that CS-NPK SRF has the potential to enhance plant growth. The AF pattern exhibited lower growth compared to SM/RM, attributed to plant competition. CS-NPK SRF demonstrated a slower nutrient release (47.65% N; 85.01% P; 31.80% K) compared to conventional fertilizers. This slow release could potentially reduce nutrient loss to the environment while enhancing plant nutrient absorption.

Abstract

Land use changes in forest areas for specific purposes (KHDTK)in Mandiangin, South Kalimantan affect the vegetation diversity loss and physical soil properties changes. This study aimed to analyze vegetation characteristics and soil physical properties across different land cover types (rubber/RB, bare land/BL, simple agroforestry/SA, complex agroforestry/CA, and natural forest/NF) on various slope positions (above, middle, and bottom). The method used was purposive sampling for vegetation analysis in 5 land cover types and 3 slope positions with three replications (45 plots). Parameters observed for soil physical properties were Bulk Density (BD), Particle Density (PD) and Porosity The total number of individuals in NF, SA, CA, RB, and BL in order is (1,713,333, 1,035,000, 768,333, 444,167, 375,000 individuals/ha individuals). The dominant species in natural forests are alaban and bangkal gunung, complex agroforestry namely rambutan, durian, nangka, avocado, matoa and mahoni, simple agroforestry namely jengkol, kemiri and mahoni, rubber plantations namely karet, bare land namely karamunting. The highest bulk density was found in natural forest and rubber (1.21 g/cm³). The highest porosity was found in bare land (53.34%) and the lowest in rubber (44.57%). These findings indicate that variations in land cover and slope significantly affect soil physical properties, which is important for sustainable land management. Keywords: Agroforestry, land use covers, soil physical properties

Abstract

Soybeans is one of important food sources in Indonesia mainly as protein resources. The needs of soybeans which increasing and lower number of cultivation land causes soybeans import. Soybeans productivity improvement could be done by agroforestry system. Mindi and sentang are a fast growing species which famously cultivated at this time. One of benefit gained from agroforestry system is providing sources of organic material. Planting combination between mindi and sentang with soybeans could give organic material such as from mindi leaves and sentang leaves. This research aimed to examine the response of soybeans growth to the additional of leaves. The experimental design used was Complete Random Design (CRD) with single factor and seven treatments (control, dry whole, dry chopped, dry powder, wet whole, wet chopped, and wet powder. This research shows that the addition of sentang leaves does not impact to the diameter and height growth. The additional of mindi leaves give not significantly different to the growth of soybeans diameter, total dry mass, and total wet mass. The additional of sentang leaves give effect to the growth of number of leave, total wet mass, total dry mass and total pud mass. The additional of mindi leaves give significant impact to the height, number of leaves, and pot mass. The treatment give best impact to total pud mas was sentang dry leave chopped and mindi dry leave whole.Key words: Agroforestry, Azadirachta excelsa, Glycine max, Melia azedarach

Abstract

Perkebunan Bangelan PTPN I Regional 5 terletak di Desa Bangelan, tepatnya di Kecamatan Wonosari, Kabupaten Malang, Jawa Timur. Total luas areal konsesi Perkebunan Bangelan adalah 883,20 hektare, yang terdiri dari dua divisi perkebunan: Afdeling Besaran dan Afdeling Kampung Baru. Akibat perubahan iklim, Perkebunan Bangelan mengalami penurunan produksi kopi. Penyebab penurunan ini antara lain terganggunya sistem pembungaan akibat perubahan iklim yang tidak terjadi, serangan hama yang menyerang tanaman kopi, serta serangan gulma yang menyerap unsur hara sehingga terjadi persaingan antara tanaman kopi utama dengan gulma. Tujuan penelitian ini adalah menganalisis keanekaragaman vegetasi dalam sistem agroforestri kopi dan mengestimasi cadangan karbon pada berbagai pola agroforestri. Metode yang digunakan dalam penelitian ini adalah purposive sampling, berdasarkan tegakan agroforestri yang representatif. Sebanyak 27 petak dibuat dengan ukuran masing-masing 20 m x 20 m. Petak-petak tersebut tersebar pada tiga petak per tahun tanam, dengan luas total 1,08 ha. Kombinasi dominan pada sistem agroforestri yang diterapkan Kebun Bangelan dalam penelitian ini adalah campuran tanaman sengon, jabon, lamtoro, dan kopi Robusta. Salah satu tujuan pola tanam ini adalah untuk mengatur intensitas cahaya matahari yang masuk, yang oleh pengelola Bangelan disebut sebagai metode "tabur bintang". Jenis tanaman yang dominan untuk semua kelas semai, tiang, pancang, dan pohon adalah Leucaena leucocephala dan Coffea Robusta. Rata-rata stok karbon sebesar 21,86 ton, dan total stok karbon sebesar 196,74 ton. Total stok karbon tertinggi sebesar 29,24 ton, yaitu pada tahun tanam 1935. Pola agroforestri yang memadukan beragam jenis naungan dengan kerapatan tajuk terbukti paling efektif dalam mendukung keanekaragaman hayati dan meningkatkan penyerapan karbon.
