Abstract

Utilization of ex-mining land for agricultural extensification is an opportunity to solve the problem of food and environment. This paper discusses prospective utilization of ex-mining land for agricultural extensification. Mining area equipped with a business license for mining in Indonesia is around 2.2 million ha under Coal Concession Agreement, and 2.9 million ha under the Contract of Effort. A part of land is already finished being mined, and be managed properly in order to benefit the community and not damage the environment. The initial steps that need to be done is mapping of mined lands, included a status of ownership (land tenure), so that subsequent use of both for agriculture and other businesses can be sustainable. Land reclamation is necessary to increase capacity and efficiency for biomass production. Determination of land use types, should be based on land tenure, bio-physical conditions of land, and the needs of the community or local government. In the future, mining land management requirements is not enough simply by opening a feasibility study for mining operations, but need to be accompanied also with itsclosure plan (planning of closures), which includes environmental protection and mitigation of socio-economic problems. This needs to be one of the terms of the granting of mining permits.

Abstract

The objectives of this research are : (1) to find enrichment substance from various organic material to increase the effectiveness of the soil conditioner, (2) to study the effect of humic substance contained in organic matter on soil properties and crop productivity. Research preceded by humic substance extraction from various organic matter. Reseach was conducted at green house using Ultisols from Taman Bogo, Center of Lampung. The experimental design used a factorial with four replications, treatment that tested were factor I: some organic material: municipal waste compost, manure compost, coal and peat, whereas factor II: enrichment types: extracted (HLS) and no extracted. The results of the research showed that HLS (humic like substances) from peat contained the highest humic substances (humat and fulvic acid), whereas HLS from manure contained the lowest humic substance. Manure was better applied in the form of compost than HLS. Organic materials with a high C/N ratio and low nutrient content (i.e. coal, peat, municipal wastes), that was applied in HSL form did not effect plant growth and biomass production significantly.

Abstract

Forest conversion to coffee-based farming systems has raised concern among many stakeholders since it may create serious impact to the deterioration of forest functions, declining soil productivity in particular and land degradation in general. Study on the impact of forest conversion on changes of soil quality, and the role of coffee for soil quality recovery has been conducted at Bodong and Laksana Sub Village of Sumberjaya Village, West Lampung. In Laksana, the observed landuse consisted of young (< 3 years) coffee plantation, mature (> 10 years) coffee, mix farming (multistrata), caliandra and forest, while in Bodong are young and mature coffee plantations and forest. The soil quality parameters used in this experiment were soil organic matter status and soil physical properties. Changes of soil quality as affected by forest conversion to coffee farming depends on soil resistance (resilience to structural break down). Soils with low resistance are easier to degrade than those with high soil resistance. The mix (multistarata) system shows better impact on soil quality than monoculture system does.

Abstract

Summary Pseudomonas fluorescens PG7II.1, Flavobacterium sp. PG7II.2, and  Pseudomonas diminuta PG7II.9 have a potential to produce exopolysaccharide which help the  formation and stabilization of soil aggregate. These bacteria have been isolated from the rhizosphere of Saccharum officinarum.  Exopolysaccharide production in ATCC 14 liquid medium with sucrose was higher than that obtained from glucose, lactose, and 4-hydroxyphenil acetic acid       (4-HAA) as a carbon sources. Producing of exopolysaccharide from these bacteria were 8.04 (P. fluorescens PG7II.1), 2.0 (Flavo-bacterium sp. PG7II.2) and 1.82 mg/mL (P. diminuta PG7II.9). Aggregate Stability Index (ASI) of mineral soil material was 114 when inoculated by these isolates after 60 days incubation period at ambient temperature. The ASI value of inoculated mineral soil material significantly different with uninoculated. The optimum of bacterial suspension to increase aggregate stability of mineral soil material was 12.5% (v/w) consisted of 109 CFU per mL.  Ringkasan          Pseudomonas fluorescens PG7II.1, Flavobacterium sp. PG7II.2, dan Pseudomonas diminuta PG7II.9, memiliki potensi dalam menghasilkan eksopolisakarida untuk pem-bentukan dan kemantapan agregat tanah. Ketiga bakteri tersebut diisolasi dari rhizosfer Saccharum officinarum. Sukrosa merupakan sumber karbon terbaik untuk produksi eksopolisakarida di dalam medium cair ATCC 14 apabila dibandingkan dengan glukosa, laktosa, dan 4-hydroxyphenil acetic acid  (4-HAA). Eksopolisakarida yang dihasilkan dari ketiga bakteri tersebut masing-masing 8,04 (P. fluorescens PG7II.1); 2,0 (Flavobacterium sp. PG7II.2) dan 1,82 mg/mL (P. diminuta PG7II.9). Inokulasi ketiga isolat tersebut ke dalam bahan tanah mineral memberikan indeks stabilitas agregat (ASI) sebesar 114 setelah 60 hari inkubasi pada suhu ruang. Nilai indeks ini berbeda secara nyata apabila dibandingkan dengan bahan tanah mineral tanpa inokulan. Jumlah suspensi bakteri yang diperlukan untuk meningkatkan nilai indeks stabilitas agregat di dalam bahan tanah mineral secara optimum ialah 12,5% (v/b), dengan jumlah populasi bakteri 109 CFU   per mL.
