Abstract

This study aims to determine the chemical characteristics of peat soil in various depths of water drainage. This research was conducted in Rasau Jaya General Village Rasau Jaya Sub-district, Kubu Raya Regency. Soil analysis was conducted at Soil Chemistry and Soil Fertility Faculty of Agriculture, University of Tanjungpura Pontianak. Soil sampling is done by disturbed soil sampling method and done by diagonal. Soil sampling was conducted on 3 plot of land observation, consisting of P0 without drainage channel, P1 drainage water channel depth 30 cm and P2 water depth of drainage channel 60 cm. Each plot is 40 x 50 m in size and there are 5 observation points. Each observation point there are 2 depths of 0-20 cm and 20 - 40 cm. The method used is descriptive data analysis to see comparison of chemical characteristics of peat soil in each plot of land P0, P1, and P2 which contained some water depth of drainage channel. The parameters observed in this study were soil reaction (soil pH), cation exchange capacity (CEC), base saturation (KB), N-total (%), P available (ppm), K (cmol (+) 〖kg〗 ^ (-1)), Ca (%), Mg (%), C-Organic (%). Keywords: Chemical Characteristics, Peat, Drainage.

Abstract

ABSTRACT Utilization of Alluvial soil as a growth medium, often faced with various limiting factors such as varying levels of fertility, diverse soil acidity, low organic matter content and availability of nutrients, especially nitrogen, phosphorus, and potassium.The is research was conducted in the Faculty of agriculture experiments station, Tanjungpura University. The Method used in the study was field experiment with complete design of stacaments of oil palm empty fruit bunces compost application. The compost application consists of p1 = 0 g/polybags, p2 = 105 g/polybags, p3 = 155 g/polybags, p4 = 205 g/ polybags, p5 = 255 g/polybags. Each treatment is repeated 4 times and each unit ansist of one melon plant per polybag thus thare was 20 plant for field experiment. The results showed that the compost of palm oil blanks is real effect on the soil pH observation variable, but has no noticeable effect on the absorption of nitrogen, phosphorus, and potassium plant and dry weight of plants. Based on the results of the analysis, it can be seen that soil pH before treatment is 4.15 (very sour), after given the average treatment of soil pH increases range from 6.10 (somewhat sour)-6.86 (Neutral). Nitogen-Total soil before treatment is 0.72 % (high), after treatment increased to 0.79 %-0.96 % (very high). -Available soil before treatment is 9.67 ppm (very low), after treatment increased to 33.99 ppm (height)"“43.17 ppm (very high). Potassium can be exchanged before the treatment of 0.33 cmol (+) kg-1 (medium), after which the treatment is increased to 0.48 cmol (+) kg-1 (medium)"“0.81 Cmol (+) kg-1 (high). Based on the results of the research of the average-the highest rate of compost is the effect of oil palm waste for nitrogen absorption, phosphorus, potassium and dry weight of plants in the treatment of P4 (205 g tkks). This has been optimized for the optimal compost delivery of palm oil to the alluvial soil. Key words: Palm Oil, Composting, Alluvial Soil

Abstract

Evaluasi lahan merupakan suatu pendekatan atau cara menilai potensi sumber daya lahan. Hasil evaluasi lahan akan memberikan informasi dan arahan penggunaan lahan yang diperlukan, dan akhirnya nilai harapan produksi yang kemungkinan akan diperoleh. Penelitian ini bertujuan mengidentifikasi faktor-faktor pembatas untuk tanaman lada dan karet di Desa Trikembang Kecamatan Galing Kabupaten Sambas.Penelitian ini dilaksanakan di Desa Trikembang, Kecamatan Galing, Kabupaten Sambas. Analisis sampel tanah di Laboratorium Kimia dan Kesuburan Tanah, Fakultas Pertanian, Universitas Tanjungpura. Penelitian ini dimulai dari 09-11 juli 2018. Hasil penelitian menunjukkan bahwa terdapat satu Satuan Peta Tanah yaitu Typic Fluvaquents. Kesesuaian lahan aktual pada jenis tanah Typic Fluvaquents (SPT 1) adalah tidak sesuai permanen (N2) dengan faktor penghambat untuk tanaman lada dan karet yaitu drainase, media perakaran dan retensi hara. Rekomendasi perbaikan pada SPT 1 adalah pembuatan saluran drainase, pemupukan, pengapuran, tanpa olah tanah yang berlebihan, penggunaan bibit unggul serta teknik budidaya yang baik maka kesesuaian lahan potensial untuk tanaman lada dan karet pada SPT 1 menjadi cukup sesuai (S2).
