Carbon emissions from oil palm development on deep peat soil in Central Kalimantan Indonesia

ABSTRAK Tanaman kelapa sawit ditanam hampir pada semua jenis tanah seperti gambut, liat berlempung dan lempung berpasir dengan proporsi kandungan tiap tekstur tanah berbeda-beda dilapangan. Cendawan mikoriza arbuskular (CMA) merupakan mikroorganisme tanah yang berperan sebagai mikroba perombak, membantu tanaman dalam penyerapan unsur hara dari tanah. Penelitian ini bertujuan mengidentifikasi jenis dan populasi spora mikoriza pada beberapa tekstur tanah dipertanaman kelapa sawit. Penelitian dilakukan pada 3 (tiga) lokasi perkebunan kelapa sawit di Kabupaten Sampit, Kalimantan Tengah, yaitu di lahan PT. Sapta Karya Damai (SKD), PT. Agro Bukit dan areal pertanaman kelapa dan kelapa sawit milik petani di Samuda besar. Penelitian dilaksanakan pada bulan Maret sampai dengan Juni 2015. Pengambilan contoh tanah dilakukan secara Purposive Sampling. Analisis contoh tanah dilakukan di Laboratorium Pengujian Balittro - Bogor. Parameter yang diamati, yaitu pH, kelembaban tanah, jenis dan jumlah populasi spora mikoriza. Hasil penelitian menunjukan bahwa mikoriza yang ditemukan adalah dari jenis Glomus dengan populasi bervariasi menurut jenis tanah, yaitu berkisar antara 175,3 - 283 buah per 100 mg tanah. Populasi tertinggi, yaitu 283 spora per 100 mg tanah ditemukan pada jenis tanah gambut di perkebunan kelapa sawit PT. Agro Bukit yang belum berproduksi (umur <5 tahun). Populasi terendah, yaitu 175,3 spora per 100 mg tanah ditemukan pada tektur tanah liat berlempung di lokasi perkebunan kelapa sawit PT. Agro Bukit yang telah berproduksi normal (umur >10 tahun).Kata kunci : Cendawan, mikoriza, tekstur, tanah, kelapa sawit. Identification of The Fungie Micorhyza Asbuscular on Saveral Soil Textures at Oilpalm Plantation, Central Kalimantan ABSTRACT Oil palm trees planted in virtually all types of soil such as peat, clay and sandy clay with argillaceous proportion of the content of each soil texture is different in the field. Arbuscular mycorrhizal fungie (FAM) is a soil microorganisms that act as microbial crusher, helps plants to absorb nutrients from the soil. This study aims to identify the types and populations of mycorrhizal spores in soil texture on oilpalm plantation. The study was conducted at three (3) locations oil palm plantations in the district of Sampit, Central Kalimantan, namely in te area of PT. Sapta Karya Damai (SKD), PT. Agro Bukit and coconut plantations and oil palm farmers in Samuda Besar. The experiment was conducted in March and June 2015. Soil sampling is purposive sampling. Analysis of soil samples carried out in the Laboratory Testing Balittro - Bogor. The parameters observed were pH, soil moisture, type and number of mycorrhizal spores population. The results showed that mycorrhizae are found are of the type Glomus with a population varies according to the type of soil ranged between 175.3 to 283 pieces per 100 mg of soil. The highest population, namely 283 spores per 100 mg of soil found in the peat soil types in PT. Agro Bukit oil palm plantations wihich is not yet in production (<5 years). Lowest population is 175.3 per 100 mg of spores found in soil texture argillaceous clay in PT. Agro Bukit oil palm plantations who have production (>10 years).Keywords : Fungi, michorrizal,textur, soil, oil palm.

Nutrients Availability

The increment of peat soil productivity meets through ameliorant addition. Ameliorant sources can be obtained from oil palm plantation and electric steam power station waste. The study aimed at investigating the ability of the oil palm fruit empty bunch (OPFEB) biochar, palm oil boiler ash (POBA) and coal fly ash (CFA) as alternative ameliorants besides compost to improve nutrient availability in peat soil of Central Kalimantan. Treatments tested were OPFEB biochar, POBA, CFA, compost, OPFEB biochar+compost, POBA+compost, and CFA+compost. The seven treatments were arranged in a completely randomized design of single factor with four replications. The results revealed that the ameliorants increased peat soil pH at a rate of 0.7 compared to those in initial soil used and available P of 135.7% even though there was no significant increment of exchangeable cations of K, Ca and Mg. Mixing of biochar, POBA or CFA with compost improved nutrients availability in peat soil.

Four Levels

Development of oil palm plantation on peatland was faced with hydrophobicity problem caused by over drained. Hydrophobicity could reduce water retention and nutrient availability in the peat soil. Beside of proper water management application, addition of soil ameliorant which contain iron could increase stability and improve peat soil fertility. The study was conducted to obtain the effect of steel slag on peat soil properties and hydrophobicity. In this study, peat soil was incorporated with steel slag and incubated in 60 days period. The research was employed completely randomized design (CRD) factorial 2 x 2 x 4. First factor is peat maturity consists of two levels: sapric (S) and hemic (H), while the second factor is soil moisture which also consist of two levels: field capacity (W1) and dry (under the critical water content) (W2). The third factor is steel slag dosage which consist of four levels: 0 g pot (TB0), 7.17 g pot (TB1), 14.81 g -1 -1 pot (TB2), and 22.44 g pot (TB3). The result showed that application of steel slag significantly increase of soil pH, ash content, and water retention at pF 4.2. Furthermore, application of steel slag significantly reduce time for water reabsorption (wettability) in sapric. On the other hand, there are negative corellation between water penetration and soil pH, ash content, and water retention at pF 4.2. Overall, application of steel slag could increase wettability and prevent peat soil hydrophobicity.

ABSTRACTPopulation of soil palm weevil pollinator Elaeidobius kamerunicus FAUST and its impact on fruit setvalue at clay, sandy and peat soil types in central Kalimantan, di IndonesiaOil palm weevil pollinator Elaeidobius kamerunicus Faust plays an important role in the increasing oilpalm fruit set value. Along with the development of oil palm, fruit set problems occurred in recentdecades in some parts of Indonesia. An experiment was carried out on a seven years old oil palmplantation located at Selangkun Estate, Kotawaringin Barat, Central Kalimantan, Indonesia to find outthe influence of population E. kamerunicus on pollination efficiency at clay, sandy and peat soil types.Relative to other soil types, a high weevil population on male (50,811 weevils/ha ; 72 weevils/spikelet)and female (219 weevils) inflorescences had been recorded at clay soil. Fruit set value on clay soil 58.9%and significantly different with sandy soil of 49.8% and peat soil of 46.4%. Population E. kamerunicusper ha influenced fruit set value at clay, sandy and peat soil types. Number of E. kamerunicus visitedfemale inflorescences did not influenced fruit set value at clay, sandy and peat soil types.Keywords: Clay soil, Elaeidobius kamerunicus, fruit set, peat soil, population, sandy soil ABSTRAKSerangga penyerbuk kelapa sawit Elaeidobius kamerunicus FAUST berperan penting dalam peningkatannilai fruit set kelapa sawit.
