The long-term cultivation of tobacco (Nicotiana tabacum) plant in the Sindoro mountainous zone of Central Java has resulted in soil quality degradation that could affect economic development in the region if sustainable production practices are not identified. The objective of the study was to identify appropriate indicators for assessing soil quality on tobacco plant. The quantitative soil quality indicators were total organic-C, pH, available P and available K (chemical), soil depth, bulk density, AWC (available water capacity) and soil aggregate stability (physical), and qCO2 (soil respiration), MBC (microbial biomass carbon) (biological). The decreases in the soil aggregate stability, available water capacity, cation exchange capacity, soil respiration, microbial biomass carbon and total organic-C; or increases in bulk density (compaction), available P, available K and total nitrogen indicated the decrease in soil quality due to long-term tobacco production. The result of this research showed that the change of soil quality had occurred in Sindoro Mountain. The Soil Quality Index (SQI) for three land use systems in Sindoro mountain (forest, mixed farm, and tobacco) were 0.60, 0.47, and 0.57, respectively. The comparison of these rates with soil quality classes showed that the soil quality presented moderate to good level of quality; class SQI.

Degraded agricultural lands in the arid tropics have low soil organic carbon (SOC) and hence low productivity. Poor farmers that their livelihoods depend highly on these types of lands are suffering. Cropping strategies that are able to improve the soil productivity are needed. In the present study, some intercropping models of food crops with bio-energy crop of castor (Ricinus communis L.) were tested to assess their potential to improve the degraded land productivity. The intercropping models were: (1) castor - hybrid maize, (2) castor – short season maize, (3) castor – mungbean, and (4) castor –short season maize – mungbean. The results show that yields of the component crops in monoculture were relatively the same as in intercropping, resulted in a high Land Equivalent Ratio (LER). The highest LER (3.07) was calculated from intercropping castor plants with short season maize crops followed by mungbean with intercropping productivity of IDR 15,097,600.00 /ha. Intercropping has a great potential to improve degraded agriculture land productivity and castor is a promising plant to improve biodiversity and area coverage on the land.

Four packages of peanut technologies, PTB1 (soil tillage, certified seed, dibbling with 40cmx10cm and 2 seeds/hole, seeds treatment, fertilizer 200 kg/ha Phonska (NPK fertilizer), and pests control with IPM methods), PTB2 (similar to PTB1 except for no seed treatment and fertilizer of urea for 50 and SP36 for 100 kg/ha), PTB3 (similar to PTB2 except for 40x15cm spacing and fertilizer of urea 50 kg/ha), and PTP (famer practice, uncertified seeds, irregular spacing, no seed treatment, no fertilizer, and no pest control) were examined the agronomic adaptability and economy value in pumice stone mining land at the Akar-akar Village of North Lombok District. Each package that was applied on an area of 0.5 ha was repeated three times at different farmers group. Economic analysis was performed to obtain revenue over variable costs (RAVC) and marginal benefit cost ratio (MBCR). The results showed that the highest fresh pod yield (4.50 t/ha) and the highest dry pod yields (2.30 t/ha) were observed for PTB1. These values, however, did not significantly different from those of other PTP treatments. The lowest fresh and dry pod yields were observed for at PTP treatment and these were significantly different from all PTB treatments. The highest of net income of farmers from the application of package of technologies was obtained from the PTB1 (Rp 8.970.00), while the highest MBCR value was obtained from the PTB3 (5.51). This indicated that the PTB3 was the promising peanut package of technology that may be applied on abandoned pumice stone mining land.

Competition between food crops and bioenergy crops in using agricultural lands should be avoided. Bioenergy crops such as Jatropha, should be grown on underutilized or degraded agricultural lands only to improve the land productivity and land coverage. Yield potential of five Jatropha curcas L. accessions of West Nusa Tenggara, Indonesia was evaluated on a degraded agriculture land at district of Kayangan, North Lombok, Indonesia. The experiment was conducted using a Randomized Complete Block Design with three blocks, and 24 plants per plot of each accession for five years. Yield components showed significant differences among accessions. Better yield performance was showed by West Lombok, Sumbawa, and Bima accessions e.g. 6.004 kg/ha, 5.885 kg/haand 5.548 kg/haat five years of age respectively. However, the yearly yield improvement was reduced after the plant reached three years of age and it was not followed by a geometrical progression based on dichotomy brancing system of the Jatropha. The high yielding accessions have a good potential to be grown on degraded agricultural lands to produce bioenergy as well as to reduce soil erosion.

Publisher : Brawijaya University

An experiment involving the application of organic matters, either fresh or composted, application of bioagent Trichoderma sp. was conducted to suppress basal stem rot caused by S. rolfsii on peanut. The research was conducted at dry land in Amor-Amor North Lombok District with the pump water well system. The experiments were arranged as split plot design with the main plot was pathogen inoculation and non pathogen inoculation. As sub-plot were the addition of organic matters and or addition of bioagent Trichoderma sp. plus two control treatments. Pathogen S. rolfsii applied as fragment mycelia of 1 x 10 6 fragment/ mL with the number of 10 L/plot. Inoculation of the pathogen was conducted when seedlings were about one month old. The bioagent Trichoderma sp. was applied 50 g/plot as powder in the same time of organic matters application (before planting the seeds). The results showed that application of composted organic matters reduced disease incidence 6-10%, while application as fresh organic matters reduced 1-6%. Combination between application of bioagent Trichoderma sp. with fresh and or composted organic matters suppressed disease incidence 8-10% and 8-12% respectively. Application of bioagent alone on planting medium reduced disease incidence 7.5%. Application of composted organic matters with bioagent Trichoderma sp. increased the number of fresh plant biomass 4.93-11.78 kg.

The productivity of private forest land by using agroforestry of Canna edulis Ker aims to achieve food security at the smallholder level. The purpose of this study was to determine the effect of agroforestry cropping patterns on productivity and quality of Canna edulis Ker tuber on private forest land. The study was conducted in dry area of the private forest land who are administrativelyincluding Tenggerraharja Village area, SukamantriSubdistrict, Ciamis District, West Java Province, Indonesia. The planting of Canna edulis Ker was implemented under the 32 months old Manglieta glauca BI stands. The main plots were three pruning intensity of Manglietia glauca BI stands i.e. P0 (0 % ) , P1 (50%), and P2 (75%). The sub plots were three planting spaces of Manglietia glauca BI, i.e. S1 (2m x 2m), S2 (2m x 3 m), and S3 (3m x 3m). The planting of Canna edulis Ker by monoculture technique was conducted as a comparison. The results showed that the interaction of planting space and pruning intensity gave a significant result on height growth, wet weight and dry weight of plant, wet weight and dry weight of Canna edulis Ker tuber. The growth of Canna edulis Ker that ranged from 181.85 cm (P0S1) to 186.30 cm (P1S1) were higher than the monoculture system on Canna edulis Ker (138.20 cm). The wet weight and dry weight of tuber that ranged from 2089.3 g and 1429.99 g (P2J2) to 3695.5 g and 2678.09 g (P1S2), whreas those in the monoculture system on Canna edulis Ker were 2363.1 g and 1528.7 g. However, the protein, fiber and carbohydrate contents of P0S1, P1S1, P2S1 treatments were lower than those of the monoculture system on Canna edulis Ker. The planting pattern of agroforestry were able to improve the plant height of Canna edulis Ker tuber but giving less percentage of carbohydrate and protein of tuber than the monoculture.

Kalilo River is one of the sights that is always visible to the people who come cross to Banyuwangi. However, there are many trash and animal (human) defecation in the Kalilo river that may impair the beautiful scenery of the river. This study was aimed to measure whether or not the physical, chemical and bacteriological parameters of the river water meets the criteria of Class II Water Quality Standard. River water samples were collected from upstream, midstream and downstream of the Kalilo river for suspended solid, sulfate, total phosphate, BOD, COD, DO, anionic detergent, total coliforms. Results of water analysis showed that the suspended solid, sulfate, total phosphate, BOD, COD, DO, anionic detergent, total coliform contents exceeded standard limit of the of Class II Water Quality Standard. Such conditions affect physical, environmental and economic development of the district. A Communal Waste Treatment Plant, Anaerobic Baffle Reactor (ABR), is recommended to overcome the problems.

Journal of Degraded and Mining Lands Management Vol 1, No 3 (2014)
Publisher : Brawijaya University

Land degradation was exacerbated and its management was challenged by population growth and global climate change. The impacts of land degradation on food security, ecosystem services and biodiversity become a more serious problem particularly in developing countries. Biochar, based on the current research findings, is capable to amend degraded lands. This paper reviewed relevant biocharproperties and identified the opportunities of its using for recovering deteriorated lands.Biochar was traditionally recognized as a good absorbent, energy source, and its ash was used by farmers to recover soil fertility. Recent findings revealed that application of biochar improved soil water retention, enhanced soil aggregation, decreased soil bulk density and increased soil infiltration. It also increased soil cation exchange capacity, soil pH, mineral nutrients, reduced nutrient leaching, support microbial population and activities, and suppressed the pest. The sorption capacity of biochar to soil and water pollutants such as Pb, Cu,Ni, Cr, Cd,dioxine, atrazine, and concurrently eliminatedthe environmental problems such as hypoxia, eutrophication, and algae bloom, have also been investigated. Investigation on its role to mitigate climate change revealed that biochar is capable in reducing greenhouse gasesemissions such as CO2, N2O, and CH4. All those beneficial effects of biochars were attributed to its high porosity, large surface area and surface charge, high carbon, ash and nutrient content, and its stability to be degraded. Thus, biochar could be potential for ameliorating degraded lands.
