Planting of oil palm in peatland has been limited by soil physical, chemical properties, and hydrology, that`s way needed improvement on those matters to increase the productivity of peat and oil palm in peat soil by compacting. The purpose of this compacting is to improve the soil's physical, chemical properties, and soil moisture. A sampling of soil, water, and leaf were done in consecutive block 5,4,3,2,1,0 year after compacting and of planting done 4 years 10 months, 3 years 9 months, 2 years 9 months, 1 year 10 months, 11 months and 2 months, control used in this trial are origin condition (forest). Increasing bulk density was found at compacting block with 30 cm depth from the surface with the lower in 2 years after compacting at 0.09 g/cm3 and highest 4 years after compacting 0.4 g/cm3. In-depth of 60 cm from surface was found no increasing the bulk density 3 years after compacting 0.0 g/cm3 and the highest on 5 years after compacting 0.3 g/cm3 compared to forest. Decreasing on permeability in-depth 30 cm at 4 years after compacting 7.47 cm/jam and close to forest permeability 51.11 cm/hour is 2 years 43.6 cm/hour. As represent rise capillary consistently water content ≥ 80% achieved at depth 20 cm of surfaces on all block. Compaction doesn't regard pH, C organic, basa's saturation, capacity exchange cation. On depth 30 cm P-total lower on s without compaction at 599.6 ppm and above 871.6 ppm on 5 yr than forest 585 ppm. P available most low 58.1 ppm happens on 4 yr afters is compacted and p available forest 53.9 ppm. Nutrient content B, Cu and Zn at soil not influenced by compaction. Fosfor (P) in water increases with added years after compaction lower at 39.1 mg/L in the block without compaction compare of forest that 40.8 mg/L.

The aim of this research was to studied the nature of soil chemistry and growth of agarwood (Aquilaria malaccensis) as an intercropping plant in palm oil land plantations that applied EFBPO compost and biochar. The study was conducted in Bukit Kemuning from May 2018 to December 2019. This study used randomized block design. The treatment is applied EFBPO compost and biochar with 7 levels, namely : without EFBPO compost and biochar, gived 0.5 kg EFBPO compost per a plant, gived 0.5 kg EFBPO biochar per a plant, mixed at dose 0.25 kg EFBPO compost and 0.25 kg EFBPO biochar per a plant, gived 1 kg EFBPO compost per a plant, gived 1 kg EFBPO biochar per a plant, mixed at dose 0.5 kg EFBPO compost and 0.5 kg EFBPO biochar per a plant. Each treetment was repeated 3 times. The observed parameters were soil chemical properties, chlorophyll content, plant height, number of branches, diameter of the stem and leaf area. The results showed that the provision of EFBPO compost or biochar at dose of 0.5 kg or 1 kg per a plant and mixed both at a dose of 0.25 kg and 0.25 kg or 0.5 kg and 0.5 kg per a plant to increase Organic C, P total, K total, KTK and decrease Al dd each 61.83%-102%, 17.18%, 28.04%-64.09%, 23.98% and 14.29%-57.14% compared to control. It also increases plant growth, such as increases plant height, number of branches, diameter of the stem, and leaf area, each 0.67%-56.72%, 5.50%-22.17%, 7.69%-52.88% and 5.73%-125% compared to control.

The growth of oil palm plants, such as height, additional fronds, and stem diameter, depends on the soil condition and its physical properties. Good soil physical properties will support the growth of oil palm plants. On marginal lands such as ex-mining land and sub-soil soil that has poor soil physical properties, improvements must be made. Thus, palm oil cultivation on ex-mining land or subsoil land can grow well. This research aims to study solid application to various soil conditions to improve the growth and physical properties of oil palm plants. The land applied by solid is an ex-mining land subsoil land. Meanwhile, the land with flat topography has not been degraded as a control. The data analysis carried out is an orthogonal contrast test, between control with solid application and without solid application, between solid application with without solid, between among solid application (ex-mining and subsoil land), between among without solid application (ex-mining and subsoil land). The research result shows that soil physical properties and plant growth applied with solid are better than without solid, lower bulk density value, higher total pore space and water holding capacity, taller plant growth, higher palm branches quantity, larger stem diameter. Solid application in ex-mining is lower than solid application on sub-soil, with lower water holding capacity value and lesser palm fronds addition. Without solid application on ex-mining sites, the results are worse than no solid application on sub-soil, with lower water holding capacity and lower plant height. Control is better than solid and without solid applications, higher plants, higher addition of frond quantity, and larger stem diameter.

The area of oil palm plantations in Indonesia continues to increase, along with that, Palm oil mill also increases. Each Palm oil mill produces liquid waste (LWPOF) in large numbers that can be utilized. The aim of this research was to study the main effect of LWPOF application and the number of biopores and their interactions on micro nutrient content and oil palm growth. The research was conducted in oil palm plantations at the Faculty of Agriculture, Riau University from June to December 2019 in the form of experiments arranged according to a completely randomized factorial design. The first factor is the LWPOF dose which consists of 3 levels (7,5 liters, 10 liters, and 12,5 liters) and the second factor is the amount of biopores consisting of 3 levels (2, 4, and 6), repeated 3 times and there were 3 experimental plants, so that 81 units of experimental plants were obtained. The parameters observed consisted of leaf micro nutrient content, plant height increase, number of fronds, midrib width, and thickness of oil palm fronds. From the experiment, known that 7,5 liters plant increases the nutrient content of copper, and the LWPOF dose of 12,5 liters increases the height, number, width and thickness of oil palm fronds, while the number of biopores 2 and 6 increases leaf manganese nutrient content. 7,5 liters of planting followed by the number of biopores in 6 biopores increases the nutrient content of manganese in the leaves and the number of midribs of oil palm plants.

This study seeks to determine the impact of palm oil wastewater, the number of biopore holes, and their interaction on oil palm plant growth and Dystrudepts soil physical properties. This study was carried out between December 2019 and April 2019. This research was conducted using a 3x3 factorial experiment with a Randomized Block Design; each treatment was replicated three times, and each experimental unit contained three plants for 81 experimental plants. The first variable was the dosage of palm oil effluent, which consisted of 7.5 liter/plant/2 weeks, 10 liters/plant/2 weeks, and 12.5 liters/plant/2 weeks. The second factor had three levels: two biopore holes/plants, four biopore holes/plants, and six biopore holes/plants. Analysis of variance (ANOVA) was applied to the data. If the treatment is markedly different, a second test is conducted using the 5% level of the Honest Significant Difference (BNJ) test. (1) Palm oil mill effluent at a concentration of 7.5 liters/plant increased the total pore space. The effluent from a palm oil mill at a rate of 12.5 liters per plant decreases BD and PD while increasing final plant height, midrib length, leaf length, and chlorophyll content. (2) Adding two biopores per plant increased plant height, midrib length, and leaf width. The presence of four biopores per plant decreased BD and PD and increased leaf length and chlorophyll content. Six openings per plant biopores have an effect on increasing the total pore space, and (3) The interaction between LCPKS doses of 12.5 liters/plant and the number of biopores of 6 holes/plant decreases BD and increases total pore space, plant height, frond length, leaf length, and leaf breadth.
