Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian kompos eceng gondok terhadap pertumbuhan dan hasil tanaman kacang hijau. Penelitian ini telah dilaksanakan pada lahan pekarangan rumah di Desa Blang Lancang Kecamatan Jeunieb Kabupaten Bireuen dari bulan Desember sampai dengan bulan Maret tahun 2018. Rancangan yang dilakukan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) non faktorial yang terdiri dari 6 taraf perlakuan pemberian kompos eceng gondok, terdiri yaitu : K0 = Kontrol, K1 = 5 ton/ Ha , K2 = 10 ton/ Ha, K3 = 15 ton/ Ha, K4 = 20 ton/Ha, K5 = 25 ton/ha dan K6 = 30 ton/ Ha. Peubah yang diteliti dalam penelitian ini terdiri dari tinggi tanaman, jumlah cabang produktif, berat polong pertanaman, berat polong perplot, berat biji pertanaman, berat biji perplot, bobot 100 biji dan jumlah akar. Hasil penelitian menunjukkan bahwa perlakuan kompos eceng gondok berpengaruh sangat nyata terhadap tinggi tanaman pada umur 45 HST, berat polong pertanaman, berat polong per plot. berat biji pertanaman, berat biji per plot, bobot 100 biji dan jumlah akar tanaman kacang hijau. Perlakuan kompos eceng gondok terbaik dijumpai pada perlakuan 20 ton/ha (K4) Kata Kunci: Pemberian Kompos, Eceng Gondok, Kacang Hijau

Abstract

South Tapanuli , North Tapanuli, Humbang Hasundutan and Dairi districts are in the Sumatera Utara Province. These four districts are producers of the Arabica debt variety of Arabica coffee and are the source of the varieties used as plant material for research.  The aim is to determine the dosage of magnesium fertilizer through the soil and leaves on the vegetative growth of Arabica coffee of the Sigarar Utang Variety which experiences symptoms of magnesium deficiency. This research was designed by factorial Completely Randomized Block Design consisting of 2 factors, namely the dose of magnesium fertilizer 4 levels, namely M0 (0 g / plant), M1 (10 g / plant), M2 (20 g / plant) and M3 (30 g / plant) applied through the soil and leaves and the source of the variety source 4 levels, namely B1 (South Tapanuli), B2 (North Tapanuli, B3 (Humbang Hasundutan), B4 (Dairi) with 3 replications. The variables observed were the increase in plant height (cm), Leaf Area (cm2) and Magnesium nutrient content in coffee leaf tissue (%). The results showed that the treatment of magnesium fertilizer doses through soil and leaves and the source of the Sigarar Utang Variety had a significant effect on the results. The level of magnesium fertilizer dose treatment of 30 g / plant applied through soil and leaves resulted in maximum increase in plant height (cm), leaf area (cm2) and magnesium nutrient content in coffee leaf tissue (%). The highest and best source of the Sigarar Utang Variety was produced by varieties from Dairi district and the response of the plant to the application of magnesium fertilizer was more maximal absorption of nutrients through soil and leaves, so that the magnesium nutrient content in the tissue leaves (%) and plant height increase (cm) are higher than the source level of other Sigarar Utang Varietties

Abstract

Climate change poses a growing threat to global coffee production, while agroforestry systems are increasingly recognized for their ecological and economic benefits, including their potential to enhance carbon sequestration. This study aimed to analyze the carbon stock of the Gayo coffee agroforestry system in Bener Meriah Regency. Field data were collected using a purposive sampling approach based on canopy density and accessibility, covering 16 plots measured between July and September 2024. Carbon estimation was conducted using the RaCSA method developed by ICRAF. The results show that Gayo coffee agroforestry represents a complex system with diverse plant species contributing to carbon storage. The highest carbon stock is recorded for Petai (Parkia speciosa) at 28.98 ton C/ha, while the lowest occurs in red chili (Capsicum annuum L.) at 0.034 ton C/ha. The total measured carbon stock reaches 2,115.072 ton C, with an average of 124.416 ton C/ha. These findings demonstrate that the Gayo coffee agroforestry system provides a substantial contribution to climate change mitigation through aboveground carbon storage. The study concludes that enhancing agroforestry-based coffee farming has ecological and economic benefits and strengthens opportunities for implementing low-carbon agricultural certification and social forestry programs. Future research may further explore belowground carbon and long-term carbon dynamics across different management intensities.
