Abstract

Tanaman kopi termasuk ke dalam komoditas penting di Indonesia. Pada tahun 2003, produktivitas kopi di Indonesia mencapai 725 kg/ha dan menurun 0,41% di tahun 2016 menjadi 722 kg/ha. Perubahan iklim diperkirakan memiliki dampak negatif terhadap produksi tanaman kopi. Beberapa kemungkinan untuk mengurangi efek dari perubahan iklim yaitu berupa mitigasi dengan cara mengimplementasikan tanaman naungan. Potensi semberdaya air berupa simpanan air tersedia dalam tanah sangat diperlukan dalam hidrologi pertanian dan manajemen air. Tutupan vegetasi seperti tanaman penaung memiliki peran besar dalam menentukan infiltrasi. Nilai simpanan air dapat diketahui dengan memperhitungkan kandungan air di dalam tanah. Masukknya air ke dalam tanah dapat diukur menggunakan single ring infiltrometer dan analisis neraca air. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh perbedaan naungan pada tanaman kopi terhadap infiltrasi dan simpanan air di dalam tanah. Penelitian dilaksanakan di kebun kopi Desa Amadanom, Kecamatan Dampit, Kabupaten Malang pada bulan Februari hingga Mei 2018. Metode penelitian yang digunakan yaitu observasi lapang dan analisa laboratorium dengan mengunakan Rancangan Acak Kelompok (RAK) terdiri dari 3 perlakuan dan 5 ulangan. Jenis naungan yang digunakan yaitu tanaman kopi dengan naungan sengon, tanaman kopi dengan naungan pisang dan tanaman kopi dengan naungan durian. Parameter yang diamati yaitu infiltrasi dan kandungan air di dalam tanah yang dilakukan dalam 3 periode serta berat isi, berat jenis, porositas, pori makro, tekstur dan struktur sebagai pendukung penelitian. Hasil penelitian menunjukkan bahwa perbedaan naungan pada tanaman kopi memberi pengaruh nyata (p<0,05) terhadap infiltrasi air dengan total infiltrasi tertinggi terdapat pada tanaman kopi naungan sengon (309,968 ± 5,855 mm) dari total curah hujan sebesar 354,731 mm. Hasil pengamatan simpanan air, perbedaan naungan pada tanaman kopi tidak memberi pengaruh nyata (p>0,05) terhadap jumlah simpanan air di dalam tanah. Nilai simpanan air terus mengalami penurunan. Nilai tertinggi tanaman kopi naungan durian sebesar (287,0 ± 15.086 mm) di minggu 1 dan terendah pada tanaman kopi naungan sengon sebesar (239.4 ± 10.871 mm) di minggu 5.

English Abstract

Coffee plants belong to important commodities in Indonesia. In 2003, coffee productivity in Indonesia reached 725 kg/ha and decreased 0,41% in 2016 to 722 kg/ha. Climate change is expected on the production of coffee crops. Some possibilities to reduce the effects of climate change are mitigation by implementing shade plants. Potensial water resources in the form of available water storage in the soil are indispensable in agricultural hydrology and water management. Vegetation cover such as shade plants has a big role in determining infiltration. The value of water storage can be determined by measured the water content in the soil. The entry of water into the soil can be measured using a single ring infiltrometer anda water balance analysis. This research aimed to understand the influence of different shade on coffee plants toward infiltration and water storage in the soil. This research was held on the Coffee plant in Amadanom village, Dampit, Malang on February 2018 until April 2018. The research used field observation and laboratory analysis as a research method with applying Randomized Block Design (RBD) that consists of 3 treatments and 5 repetitions. This study used three types of shade named a coffee plant with sengon shade, coffee plant with banana shade and coffee plant with durian shade. The parameters observed were infiltration and water content in the soil conducted in 3 periods as well as the bulk density, particle density, porosity, macro pore, texture and structure as researech support. The results showed that the differences of shade on coffee plants gave a significant effect (p<0,05) toward infiltration of water with the highest total of infiltration found in coffee plant with sengon shade (309,968 ± 5,855 mm) from total rainfall 354,731 mm. The results of water storage observation showed that the differences of shade in coffee plants have no significant effect (p>0.05) toward the amount of water storage in the soil. The value of water storage in the soil continued to decrease. The highest value in the coffee plant with durian shade was (287,0 ± 15,086 mm) in the first week and the lowest value found in the coffee plant with sengon shade (239.4 ± 10.871 mm) in the fifth week.
