Abstract

Usaha kopi organik dapat dijadikan sebagai salah satu alternatif dalam meningkatkan mutu kopi robusta di Indonesia. Penelitian ini bertujuan untuk mengetahui pemberian pupuk guano dan growmore terhadap pertumbuhan bibit kopi robusta. Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Jabal Ghafur Glee Gapui Sigli mulai Februari sampai April 2017. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola faktorial 4x3 dengan 3 ulangan. Faktor pertama pupuk guano terdiri dari 4 taraf yaitu 1 bagian pupuk guano dengan 2 bagian tanah (1:2), 1 bagian pupuk guano dengan 3 bagian tanah (1:3), 1 bagian pupuk guano dengan 4 bagian tanah (1:4) dan 1 bagian pupuk guano dengan 5 bagian tanah (1:5). Faktor kedua konsentrasi growmore terdiri dari 3 taraf yaitu 1 gr/liter air, 2 gr/liter air dan 3 gr/liter air. Hasil Penelitian menunjukkan bahwa pupuk guano berpengaruh nyata terhadap jumlah helai daun dan panjang akar.  Pemberian konsentrasi growmore berpengaruh nyata tehadap jumlah helai daun. Adanya interaksi nyata antara pupuk guano dan konsentrasi growmore terhadap diameter pangkal batang 90 HST.Kata Kunci : Guano, growmore, kopi robusta

Abstract

Soil surface charge and cation exchange are important parameters of soil fertility in tropical soils. This study was conducted to investigate characteristics of surface charges and cation exchanges on four soil orders of the dryland in  Aceh Besar district. The soil order includes Entisols Jantho (05o16’58.41” N; 95o37’51.82” E), Andisols Saree (05o27'15.6" N; 95o44'09,1" E), Inceptisols Cucum (05º18’18,37” N; 95º32’48,04” E), dan Oxisols Lembah Seulawah (05o27’19,4” N; 95o46’19,2” E). The charge characteristics of surface charge are evaluated from the parameter of DpH (pHH2O-pHKCl), variable charge (Vc), permanent charge (Pc), and point of zero charges (PZC). In contrast, cation exchange properties are evaluated from several soil chemical properties, such as soil organic matter (SOM), base saturation (BS), cation exchange capacity (CEC), and effective CEC (ECEC). The results show that the four pedons of soil in the hilly dryland of Aceh Besar include a variable charge because it has a PZC, which is characterized by a negative surface charge with a PZC of pHH2O and has CEC dependent soil pH. PZC value varies from 3.21 – 5.26 and sequentially PZC Andisols Oxisols Entisols Inceptisols. The total CEC value differs considerably from ECEC and the sum of cations. CEC total of the soils varies from 12.8 – 34.4 cmol kg-1, whereas the ECEC values vary from 2.72 – 8.66 cmol kg-1. The highest variable charge percentage is found in Andisols Saree. In contrast, the highest permanent charge is found in Inceptisols Cucum and is positively correlated with pHH20, PZC, CEC, and sums of cations or ECEC. Improving soil quality in hilly dryland soils in Aceh Besar District can be done by decreasing the PZC status of soils with organic amendments and fertilizers or increasing the pH by using liming.

Abstract

ABSTRAKPengolahan tanah menjadi faktor penting terhadap pertumbuhan dan produksi tanaman padi, dimana proses pengolahan yang baik akan menghasilkan pertumbuhan yang optimal. Metode lintasan lintasan hand traktor pada saat pembajakan menjadi salah satu upaya untuk menciptakan keadaan tanah yang baik bagi pertumbuhan tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh perlakuan lintasan hand traktor dan bajak terhadap pertumbuhan dan hasil padi. Penelitian dilaksanakan di lahan sawah Desa Paloh Tungoh, Kecamatan Keumala, Kabupaten Pidie. Penelitian menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri dari 2 faktor. Faktor pertama, Lintasan (L0: tanpa lintasan, L1: 3 lintasan dan L2: 5 lintasan) dan faktor kedua, penggunaan bajak (B0: tanpa bajak dan B1: menggunakan bajak). Parameter yang diamati yaitu tinggi tanaman 15, 30, 45 dan 60 HST, jumlah anakan 15 dan 30 HST, panjang akar dan berat gabah basah. Hasil penelitian menunjukkan bahwa perlakuan 3 kali lintasan (L1) berpengaruh sangat nyata terhadap jumlah anakan 15 dan 30 HST, panjang akar dan berat gabah basah, namun tidak berpengaruh nyata terhadap tinggi tanaman padi umur 15, 30, 45 dan 60 HST dengan nilai terendah pada perlakuan L1 dan L2. Penggunaan bajak (B1) berpengaruh sangat nyata terhadap tinggi tanaman padi umur 15, 30, 45 dan 60 HST, jumlah anakan umur 15 dan 39 HST, panjang akar dan berat gabah basah. Terdapat interaksi antara perlakuan lintasan traktor dan penggunaan bajak terhadap panjang akar dengan perlakuan terbaik dijumpai pada L1 dan B1. ABSTRACTSoil cultivation is an important factor in the growth and production of rice plants, where a good processing process will produce optimal growth. The trajectory method at the time of plowing is one of the efforts to create good soil conditions for plant growth. This study aims to determine the effect of trajectory and plow treatment on rice growth and yield. The research was carried out in the Paddy Fields of PalohTungoh village, Keumala District, Pidie Regency. This study used a factorial randomized block design (RAK) consisting of 2 factors. The first factor is the track (L0: no track, L1: 3 passes and L2: 5 passes) and the second factor is the use of plows (B0: no plow and B1: using plow). Parameters observed were plant height 15, 30, 45 and 60 DAP, number of tillers 15 and 30 DAP, root length and wet grain weight. The results showed that the treatment of 3 passes (L1) had a very significant effect on the number of tillers 15 and 30 DAP, root length and wet grain weight, but had no significant effect on the height of rice plants aged 15, 30, 45 and 60 DAP with the lowest value at L1 and L2 treatments. The use of plow (B1) had a very significant effect on the height of rice plants aged 15, 30, 45 and 60 DAP, the number of tillers aged 15 and 39 DAP, root length and wet grain weight. There is an interaction between tractor trajectory treatment and the use of plows on root length with the best treatment found at L1 and B1.
