Most of the peatlands in Pesisir Selatan, West Sumatra have been converted into agricultural activities. Due to drainage, the peat decomposition process becomes faster. The activity of β-glucosidase is one of the enzymes that can be used as an indicator of the decomposition of organic matter and produces greenhouse gas emissions, likes CO2. Therefore, this study was conducted to identify the activity of β-glucosidase in several land uses in Pesisir Selatan peatlands. Observations were performed in several land-use types consisting of agricultural land (LP), bare land (LT), shrubs (SB), smallholder oil palm plantations (PSr), private company oil palm plantations (PSs), and forests (H). The activity of β-glucosidase was analyzed by using salicin and Na-acetate methods. The results of this study showed that the highest β-glucosidase activity was found in agricultural land use (LP). Based on the land use types, the activity of β-glucosidase follows agricultural land (LP) 3.42 μg.g-1.jam-1 > bare land (LT) 2.26 μg.g-1.jam-1 > shrubs (SB) 1.63 μg.g-1.jam-1 > smallholder oil palm plantations (PSR) 1.31 μg.g-1.jam-1 > private company oil palm plantations (PSs) 1.28 μg.g-1.jam-1 > forest (H) 0.80 μg.g-1.jam-1. Soil characteristic that significantly affects enzyme activity is water content where the higher the water content, the lower the β-glucosidase activity, and vice versa. Based on this study can be concluded that the change in land use from natural land to agricultural land triggers an increase in the activity of enzymes in decomposed peat materials.Key words: β-glucosidase, enzyme, palm plantation, land-use, peatland

The area at the foot of Mount Talang is one of the areas that excellent in agriculture, especially the cultivation of horticultural crops. In the northern area with steep slope conditions, the local community applies an intensive monoculture cropping system, this will accelerate land degradation in the long term. This study aims to examine the physicochemical properties of monoculture agricultural land in the northern foothills of Mount Talang on several slopes. This research was conducted with a survey method, soil sampling was carried out by means of purposive random sampling, on monoculture agricultural land on slopes > 45%, 25-45%, 15-25%, and 8-15% and forest as control, at a depth of 0 -20cm and 20-40cm. The results showed that the soil texture that dominates at the forest and monoculture agricultural land are dusty loam. Soil water content increases with increasing soil layer depth, soil water content in monocultures 25-45% (73.72%) is the highest. Soil volume weight ranging from 0.4-0.6 g / cm3 has the same tendency at both soil depths. The total pore space of forest land and monoculture agricultural land is a large average of 75% with high criteria. The highest soil organic C content was found in monoculture agricultural land with a slope of >45%. The pH value of H2O for all land uses was 5.15-5.29 and the pH for KCl was 4.5-5.2 for acid criteria. The cation exchange capacity was above 40 me/100g (very high criteria), the total N content was 0.8-1.6% with very high criteria, too. Based on the researchs data, the physicochemical properties of monoculture agricultural land on several slope classes matched the physiochemical conditions of the forest. The potential for land degradation is still minimal even though it is on the upper slopes of the foot of Mount Talang. However, monoculture farming while maintaining soil organic matter content must remain a priority for agricultural land management in this area.Key words: monoculture land, forest, slope, North area of foot Mount Talang

The experiment to obtain residue compost of rice straw (S) and tithonia (T) for reduce commercial fertilizers (CF) input and that effect for rice production. This research was arranged in Completely Randomized Block Design (RBD) with three replications of six treatments. The residue treatments are; A (input Urea 200 kg ha-1 (Ru) + SP-36 100kgha-1 (Rp)+KCl 75 kgha-1 (Rk)), B (Ru+2Rp), C (S 5 tonsha-1+ R), D ( S 5 tonsha-1+Ru+Pstarter (Ps)), E (T, 2,.5 tonsha-1 + J, 2,.5 tonsha-1 + 75%Ru+Ps), F (T, 2,.5 tonsha-1 + J, 2,5tonsha-1 +50%Ru+Ps). Data of research were statistically analysed. If the F-calculated was significantly different, they would be further analysed using LSD 0.05. The results showed that residue of T, 2,5 tonha-1 could reduce CF by 50 kg Ureaha-1 (25% R), 75 kg KCl ha-1 (100% R) and 90 kg SP-36ha-1 (90% R) with production 6,66 tonsha-1 Husk Rice (HC). If it is based on farmer tradition, residue of T could reduce CF by 50 kg Ureaha-1 (25% R), and 190 kg SP-36 ha-1 0.95.Key words : compost, residue, rice, straw, tithonia
